CLUTCH THE AXIS OF WHEEL PAIR AND GENERATOR FOR CONNECTION OF CARDAN SHAFT, HAVING KINEMATIC CONNECTION WITH CLUTCH THE AXIS OF WHEEL PAIR OF RAIL VEHICLE, WITH SHAFT CURRENT GENERATOR, MOUNTED ON RAIL VEHICLE

Clutch wheelset axle and generator for connecting cardan shaft, having kinematic connection with clutch wheelset axle rail vehicle, with shaft current generator,

The present invention relates to coupling of clutch wheelset axle and generator for connecting cardan shaft, having kinematic connection with clutch wheelset axle rail vehicle, with shaft current generator, mounted on rail vehicle, in accordance with the station 1 of the formula.

In towed rail vehicles without its own drive, in particular intended for carrying people, current, required for such type of vehicle, is generated mounted on it generator.

Such generator with the help of cardan shaft and step up reduction gear is connected with the axis of the wheelset rail vehicle, so that at rotation of the axis of wheel pair is launched generator. In case with rail vehicle is permitted, that in process of transition between two sections of rails or pointers, or other vozvyshennostyami entire wheel axis, together with cardan shaft and also shaft of generator can be unwanted impact, which can apply considerable harmful generator. For smoothening such of genus impacts necessary between cardan shaft and generator shaft envisage shock absorbing element, possessing elasticity of rubber, which absorbs these shocks.

On Figure 2 and 3 drawings is given form of the such of clutch wheelset axle and generator. Clutch consists of small flange (1) for reception of cardan shaft, enclosed by shock absorbing member (2), having elasticity of rubber. This shock absorbing element (2), in its turn, is surrounded by large flange of (3), which may be mounted to shaft of generator. On the structure, presented on depicted 2 and 3, shock absorbing element along outer contour is provided with a of teeth (4), while large flange has corresponding grooves, and, owing to this shock absorbing element is held in large flange with observance of accuracy this. At that, as a rule, transmission of force is effected by means of large of flange (3) and slots/of teeth (4) on shock absorbing element (2), and also small flange (1) and cardan shaft. In subject case of teeth (4) are made so, that appearing on this section force can be perceived prolongly.

At certain conditions environment or conditions of travel happens, that generator during riding is blocked. Due to this cardan shaft, and together with it wheel axle and wheel of rail vehicle also are interlocked from-rigid of transmission, and, as a result, wheels volokutsya along rails. At that applied damage and wheels, and rails, Besides, formed at friction heat can result to other damages rail vehicle or rail track. To avoid similar injuries of rail vehicle and/or rail track to cushioning member in implementation, on display depicted 2 and 3, are provided separate teeth, which are responsive deformation. When generator is blocked, the force acts on the teeth of the shock absorbing element so, that they are deflected aside, and in the long run one or several teeth of shock absorbing element proskalzyvayut. If such state is stored, then this can result to the, that separate teeth are subjected to wear or finally which break. In this case instead of wheels operates clutch, and described damages on rail track and on vehicle can be avoid. Clutch, diagram on depicted 2 and 3, may be booked in company Siemens ag by the number of the e 86060 - K5710 - A111 - A5.

After appearance of such troubleshoot rail vehicle necessary can be delivered to corresponding repair separation of, to dismantle clutch and replace the shock absorbing element. In such case of arise high costs of transportation, material and mounting operations, and on of repair time rail vehicle may not be used.

Proceeding from above passu can be conclude, in the basis of this invention is-provision of compound wheel axle with generator, which is achieved quickly, simply and with no extra costs on materials.

As a technical solution of this problem is proposed clutch wheel axle and generator according to features point 1 of the formula. Preferred embodiments of this of clutch are connected in corresponding dependent points of the formula.

Advantages of the of clutch wheelset axle and generator, made in accordance with this theory, consists in the fact, that arrangement of internal flange with the possibility of rotation relative to shock and/or to flange drive effect on disconnecting internal flange from external flange so, that at no integrity of element disconnection or rupture of is interrupted transmission of force between shafts a cardan and generator, and they can rotate independently from one another. This means, that in this case in connection with location of internal flange with the possibility of rotation relative to shock and/or relative to flange of drive is not transmission of force, so that in case of blocking generator shaft cardan shaft can rotate without increasing friction and diffusion nnogo formation of heat.

If between inner and outer shafts disengagement element is an integer or not corrupted, then transmission of forces from cardan shaft to shaft of generator is effected by means of this disengagement element, so that generator in state to current usual manner. In case of occurrence of complications on any of sections, in particular, if shaft of generator is blocked, on disengagement element are fed incommensurable with its capabilities force, and it is broken in combination. As a result, process of force transfer is interrupted and cardan shaft can rotate independently from the shaft of the generator without creating considerable friction and large-volume forming at that heat.

Also advantage of clutch wheelset axle and generator, made in according to the present invention, is, that razed disengagement element can be simple way to replace on whole. For replacing disengagement element there is no necessity in dismantling the of clutch, therefore installation of new disengagement element may be performed quickly and economically. To the same such disengagement element is relatively small and cheap part, consequently, can be to avoid considerable of material costs. Besides this, replacement of disengagement element can be to on place, owing to this there is no necessity in delivery of rail vehicle in a repair separation of.

The other course, that as alternative to clutch wheelset axle and generator in according to the present invention can be arranged and on flange of drive, that is similarly relative to driven flange, ; and in this case are stored described above advantages.

At that was proved advantage of kinematic compound disengagement element with external and internal flanges, as a result of which is achieved simplicity and rapidity of its mounting and dismantling.

In preferable structure between flange of drive and inner flange or between driven flange and inner flange should envisage roller bearing, in particular, ball by dshipnik. Owing to this roll bearing, located between flange drive or driven flange with one side and inner flange with the other side, is created definitely directed and together with this relative motion with minimum friction between both flanges. In the long run is created controlled motion relative to shaft of generator and possibility to avoid injuring separate units in a result of generation of heat, which at formed in force technical reasons.

In said improved design, at least one roller bearing preliminarily is pulled with the help of spring, in particular, by means of plate spring. In standard operation conditions of clutch wheelset axle and generator, force is transferred by means of disengagement element and any rotation of the cardan shaft relative to generator shaft is not. In a result of this, roller by dshipnand to is not subject to any or any-either of considerable forces, leading to risk of collision or insufficiency of the lubricant separate elements along dship preparations of rolling, that in turn results in damages roller bearing. It was established, that to avoid above described disorders roller under iii Typen iki should be stress by means of spring, in other words, plate spring.

In accordance with the other preferable form of performing disengagement element has place predefined of breaking. In this case cylindrical mould disengagement element can be changed to conical. At that, it was established, that is expedient arranged place predefined of destruction in zone between inner and outer flanges. Advantage considered of is, that disengagement element, adjustable in zone between the inner and outer flanges, is ruptured so, which can be to avoid pinching part of disengagement element between the inner and outer flanges.

In the following preferable structure disengagement element is located across relative to shaft generator or universal joint. Owing to this mounting or dismantled such disengagement element are outside of clutch, without special its dismantling. Replacement of disengagement element in this case is performed at significant saving of time. Also owing to this disengaging members can be substituted on place, consequently, there is no necessity in expensive transportation rail transport in corresponding repair separation of.

In other selected on the external disengagement element is installed thrust strip or limiter, at that preference given creation of edge projection or rim along the whole perimeter. In a result of this, disengagement element is inserted precisely appropriately and sufficiently deeply in clutch, to provide appropriate of mounting. In that case, if the separating element has place predefined of breaking, then due to strip is provided, the place is arranged in zone between the inner and outer flanges.

In one from selected embodiments disengagement element has hollow shape. This leads to increase of standard resistance on cut and as a result simultaneously leads to Your Exploration flow rates on materials.

In one of preferable enhancements separating element on transverse outer end is provided outside the inner thread and/or on cross inner end has internal thread. Such inner thread facilitates mounting and dismantling separating element or both its ends, and as a result creates possibility of saving further flow rates.

In one of the improved versions of inner thread outside the separating element has larger diameter compared with diameter internal thread inside the separating element. This structure has advantage, that facilitated unit or removal of separating element.

Other advantages of clutch wheelset axle and generator, made in according to the present invention, are given on applied drawings and in disclosed below versions of its realisation. Also, as described above, and given below signs may, within the framework of the present invention, be used separately or in all their combinations. Mentioned below the embodiment of the coupling should be understand not as final and only possible, and opposite to they are set in as examples of its execution. The present invention explained figures drawings, where:

Figure 1 shows schematic cradle type side part of rail vehicle with clutch wheelset axle and generator, made in accordance with the invention;

Figure 2 shows common type of known of clutch wheelset axle and generator;

Figure 3 shows incision lateral projection of clutch wheelset axle and generator according to Figure 2;

Figure 4 shows cut lateral projection of clutch wheelset axle and generator according to the invention;

Figure 5 shows detailed enlargement according to line V-V on Figure 4.

On Figure 1 shown rail vehicle, in this case, railway car 10 for carrying passengers with wheel axis 12 and mounted on it transmission mechanism 14, connected with cardan shaft 16, clutch 18 wheel axle with generator and generator 20 for production of current for of car 10. On the coupling of clutch 18 from the side of drive is installed cardan shaft 16, while on the side of the driven shaft is shaft of generator 20, which is not shown.

On Figure 2 and 3 is presented clutch wheel axle and generator, released firm Siemens ag, which from the side of drive is provided with receiving mechanism for cardan shaft, in its turn connected with elastic shock absorbing member 2. To shock 2 is attached also large flange 3, on which on the side of the driven flange is mounted shaft of generator. Elastic shock absorbing element 2 has a row of teeth 4, which enter corresponding grooves on a large flange of 3. This shock absorbing element 2 damps minor shocks, proceeding from wheel axle, to avoid damage the generator. If all-still blocking generator occurs, the teeth 4 based on occurring forces unbent to side or are sheared so, that clutch slips and is not there is a possibility of transmit force from small of flange 1 on large flange 3. In any case after such increase is required complete replacement of elastic shock absorbing element 2 to new. Also in this case on the background of increase of friction can happen raise of temperature, which may lead to further damage.

Figure 4 and 5 show the first form of of of clutch wheel axle and generator in accordance with the invention, including flange drive 22 for reception of cardan shaft 16, flange power takeoff shaft 24 for reception of generator shaft 20 and shock absorbing element 26, arranged between drive flange 22 and flange of power takeoff shaft 24.

Flange power takeoff shaft 24 consists of internal flange 28, connected with the shaft of the generator, and external flange 30, fixedly mounted on cushioning member 26, possessing elasticity of rubber, at that inner flange 28 and outer flange 30 are constructed separately (are spaced) from each other so, that does not occur any points of contact directly. At the same time inner flange 28 in the known degree of placed inside external flange 30, so that inner flange 28 can rotate inside external flange 30.

Inner flange 28 is held in rotating state by means of two ball bearings 32 on flange of drive 22, both ball of bearing 32 are located remotely or separately from each other by inserts 33a, which excludes distortion of internal flange 28 by imbalance Exploration to flange drive 22.

In a regular mode ball bearing 32 not operates, respectively no considerable value force on ball by dshipnik 32 act. With the aim of up Shunning uncontrolled movement of balls inside body ball bearing 32, which, in its turn, can result to damage the of bearing 32, in coupling of clutch 18 is provided disc spring 31, by means of expanding element ZZ outside acts on ball bearing 32, and in definite degree preliminarily its stretch, so that balls on the body of the ball by dsh Typenickname and 32 approach to installation. In that form of the disk spring 31 is pulled between spacer element ZZ or ball under iii Typen and toth 32 and inner flange 28 and acts in direction of longitudinal axis of clutch 18, T. e. on the side of the ball bearing 32.

Insert 33 and, located between two ball bearings 32, transmits force, originating from plate spring 31 with the first ball bearing 32 on the second ball bearing 32, to also preliminary pull both under iii Typenor ka.

In external flange of 30 is hole 34 and on one line with hole 34 on outer side of internal flange 28 is provided corresponding slot 36, and in such way, disengagement element 38 can be installed through hole 34 so, that it rests in slot 36 of internal flange 28.

Force, outgoing from cardan shaft 16, is transferred through the flange of drive 22 and shock absorbing element 26, possessing elasticity of rubber, on outer flange 30, and further with means of disengagement element 38 is fed on internal flange 28, and thereby to shaft of generator 20, resulting in generation of current in generator 20. In that case, if generator 20 once is blocked and shaft of generator not is launched, then disengagement element 38 is ruptured, and transmission of force is interrupted. But so as flange drive 22 at still is set in motion by the drive shaft 16, then flange drive continues rotating together with drive flange 22 and with shock absorbing member 26, having elasticity of rubber, and with an external flange 30, while the inner flange 28 is in a state of rest. In this case ball by dshipnik 32 provides occurrence of small friction between inner flange 28 and other components of clutch 18, which in its turn, does not cause formation of considerable heat due to friction. At still in case of fracturing of disengagement element 38 Ball bearings 32 avoids canting of flange drive 22 and flange power takeoff shaft 24 relative to each other, in result allows to avoid further damage.

After, as describes problem in generator 20, damaged disengagement element 38 may be is removed a mechanic on place and replaced with whole disengagement element 38, so that rail vehicle 10 again ready again for operation. Moreover, there is no necessity in transportation rail vehicle 10 in a repair separation of, so these operation can be produced on site. Disengagement element 38 is usually in the form of cylinder of hollow mould. Approximately in the middle of the disengagement element 38 is provided use of more thin material, to obtain place predefined of breaking 40.

One side of the disengagement element 38 is formed by edge projection 42, passing along the entire perimeter and protruding outside, which operates in as stop at usage of disengagement element 38 in outer flange of 30. At that edge projection 42 and place predefined of breaking 40 are arranged so, that in assembled form place predefined of breaking 40 precisely enters in clearance between inner flange 28 and outer flange 30. Owing to this is achieved then, that disengagement element 38 is ruptured in zone between inner flange 28 and an external flange 30, so that located above disengagement element 38 of part may not cause any injuries or cause minor damage.

In hole 34 and in slot 36 is provided reinforced bushing 44 for reception of disengagement element 38. This reinforced bushing more are resistant to wear compared with the very inner flange 28 or with outer flange 30, so that these flanges are protected enhanced bushing 44.

On member disconnection 38 in the area of edge protrusion 42 is provided outside the inner thread 46 and from the opposite side there is a from inside inner thread 48, intended for mounting and dismantling disengagement element 38.

Disengagement element 38 together with bushings 44 are arranged radially for simplicity mounting and dismantling disengagement element 38, since only at this design is possible release or establish disengagement element 38 at already collected coupling of clutch 18. At that, inner thread 48 from inside is made in diameter already, than the outer thread 46, thereby tool can pass from internal thread outside 46 to internal thread inside 48.

In case of with the second design, not given in this document, in contrast to to structure, displayed on Figure 4 and 5, drive with the side of the flange 24 is not is a two-component, and flange drive 22. In as this execution similarly described above first construction.

In the third form of execution, which also not shown, is provided two connection element 38, located separately above an external flange, clutch clutch and disengaging members are made similar manner. Also the installation more than two connection elements. In order to achieve uniform distribution of force is expedient ravnoudalennoe separation of connection elements over an external flange.
