Rail road car truck and fittings therefor

A rail road freight car truck has a truck bolster and a pair of side frames, the truck bolster being mounted transversely relative to the side frames. The mounting interface between the ends of the axles and the sideframe pedestals allows lateral rocking motion of the sideframes in the manner of a swing motion truck. The lateral swinging motion is combined with a longitudinal self steering capability. The self steering capability may be obtained by use of a longitudinally oriented rocker that may tend to permit resistance to deflection that is proportional to the weight carried across the interface. The truck may have auxiliary centering elements mounted in the pedestal seats, and those auxiliary centering elements may be made of resilient elastomeric material. The truck may also have friction dampers that have a disinclination to stick-slip behaviour. The friction dampers may be provided with brake linings, or similar features, on the face engaging the sideframe columns, on the slope face, or both. The friction dampers may operate to yield upward and downward friction forces that are not overly unequal. The friction dampers may be mounted in a four-cornered arrangement at each end of the truck bolster. The spring groups may include sub-groups of springs of different heights

Method of limiting angle between lengthwise axes of interconnected cars bodies

FIELD: transport. SUBSTANCE: every car body seats on one rotary bogie. Angle between lengthwise axes of coupled cars bodies is actively influenced by controlled electric actuator unless said angle takes preset value. This preset value is defined by turn angles (relative angles) of rotary bogies relative to appropriate car bodies. In compliance with first version, said angle is adjusted by kinetic and/or potential energy of car spring suspension. In compliance with second version, force acting at coupling hinge is measured to use it for adjustment of actuator. When said force varies said angle with departure from preset magnitude, said actuator is locked or stays locked.

Rail vehicle with a load carrier

The invention relates to a railed vehicle comprising a load-bearing carrier (1) in the form of a bogie frame pertaining to a two-axle bogie, whereby said load-bearing carrier (1) is supported by spring elements (2) on two pairs of wheels (4,4; 4,4). Each wheel (4) is provided with a strut rod (9) extending in the direction of the wheel housing, which is coupled respectively on one end to a wheel support (3) by means of coupling points (8, 10), adjacent to an associated wheel (4), and to the load-bearing carrier (1) on the end thereof. The pairs of wheels can turn in respect of the load-bearing carrier. In order to achieve a turning movement of the pair of wheels for a curved radial adjustment dependent upon the radius of the curved track currently travelled upon, the strut rods (9) are respectively coupled directly to the coupling points (10) directly on the load-bearing carrier (1). The coupling points (10) of the strut rods (9) of at least one pair of wheels (4, 4) on the load-bearing carrier (1) are located above the coupling points (8) of the strut rods (9) on the associated wheel support (3) in relation to the plane determined by the contact points (6) of the wheels (4) on the tracks (7) if the strut rods (9) are orientated in the direction of the wheel housing towards a central area between two pairs of wheels.

The guiding system can be performed with a center balancer disposed in the middle of the coach body or, in a second embodiment, with an independent guiding system for each of the bogies, being constituted by a balancer (36), the turning axle of which is integral with a center frame (1) disposed on each bogie, and a bar (37) is joined to the upper end of the balancer (36), the other end of which is united to a support (38) which is integral with the coach body, the lower end of the balancer (36) having a bar (39) joined to it, the opposite end of which is integral with the outside case of an oscillant fork (6) which, in turn, is integral with a frame (4) carrying the rolling assemblies, the balancer (36) having other joint (40) located above its turning axle and disposed equidistant from a lower joint with regard to the turning axle of the balancer, the bars (41) and (42) being united to this joint (40). <IMAGE>

Self steering, three-axle bogie

The invention relates to a self-steering, three-axle bogie, in particular for a rail vehicle, comprising wheel sets ( 8, 9, 10 ) and wheel set bearing housings ( 2, 3, 4, 5, 6, 7 ) allocated to said sets. According to the invention, the outer wheel sets ( 8, 10 ) are counter-coupled and can be displaced in a longitudinal direction and the central wheel set ( 9 ) can be displaced in a transverse direction and is included in the control system. The wheel set bearing housings ( 2, 4, 6 ) on one side of the running gear and/or the wheel set bearing housings ( 3, 5, 7 ) on the other side of the running gear are coupled exclusively to the wheel set bearing housings ( 2, 3, 4, 5, 6, 7 ) lying on the same side and neighbouring wheel set bearing housings ( 2, 3, 4, 5, 6, 7 ) are coupled to a first rotary lever ( 14, 26 ) that is connected so that it can rotate to the corresponding wheel set bearing housing ( 4, 5 ) of the central wheel set ( 9 ), by means of a steering linkage-rotary lever configuration.

Rail vehicle undercarriage with a load bearing implement

A rail vehicle undercarriage comprises a load bearing implement 1 in the form of the bogie frame of a two-axle bogie, wherein the load bearing implement 1 is supported on two wheel pairs 4, 4; 4, 4 by means of spring elements 2. One respective steering rod 9 that extends in the running direction of the wheels is provided per wheel 4, wherein said steering rods are coupled to the wheel carrier 3 adjacent to the corresponding wheel 4 with one end and to the load bearing implement with their other end in coupling points 8, 10. The wheel pairs can be turned relative to the load bearing Implement. In order to achieve a turning movement of the wheel pairs towards a curve- radial adjustment which depends on the curve radius of the currently used track, the respective steering rods 9 are directly coupled to the load bearing implement 1 in coupling points 10. In addition, the coupling points 10 of the steering rods 9 of at least one wheel pair 4, 4 are, referred to the plane defined by the contact points 6 between the wheels 4 and the rails 7, situated above the coupling points 8 of the steering rods 9 on the corresponding wheel carrier 3 when the steering rods 9 point toward the central region between two wheel pairs in the running direction of the wheels.

SELF-ADJUSTMENT DEVICE FOR BOGIES

Steering railway bogie

The present invention is directed to a railway bogie with a mounted vehicle body including a frame; a plurality of wheelsets and steering linkages linking the wheelsets so that the wheelsets can cooperate to be in steering alignment. The bogie has a wheelset body linkage pivotally connecting the steering linkages with the bogie body so to position the body relative to the wheelsets and two alignment rams to position the body relative to the frame. The bogie also has sensors for monitoring the yaw angle and yaw velocity. The sensor input is then processed to estimate track curvature and determine the train speed and yaw velocity of the vehicle body. The processor then actuates the alignment rams to adjust the position of the body relative to the frame in response to the track curvature and current frame positions to minimize wheel contact creepage and maximize bogie stability.

Passive steering for piece rail road bogie

传统的三件式铁路货车转向架由于刚性侧架限制轮对而妨碍了轮对实现与弯曲段的径向对准。侧架还由于轮对轴承和侧架导框颌部之间的有限间隙而限制轮对与弯曲段径向对准。本发明扩宽了侧架导框颌部以允许轮对偏转并与弯曲段径向对准。侧架由弹性体垫和轴承适配器支撑在轮对上。本发明使用弹性体垫的刚度在俯仰运动中压缩，该俯仰运动允许轮对在侧架的扩宽的颌部中以弧形向前或向后运动。弹性体垫的刚度还允许轮对使垫扭转，从而允许轮对与弯曲段径向对准。垫的弹性刚度足以在轮对与直的轨道对准时恢复。
