SLIP COUPLING

Vehicle power transmissions

A power transmission system for vehicles comprising a driving member connected to an engine crankshaft, and a driven member connected to a driving wheel, the driving and driven members being connected with each other via a one-way clutch and a friction clutch which are disposed in parallel to each other. The one-way clutch is in a connected state when a forward load is applied to the engine, and in a disconnected state when a back load is applied to the engine. The friction clutch is operated to slip when it receives a torque greater than a predetermined value. With this arrangement, power is normally transmitted from the engine to the driving wheel through the one-way clutch and the friction clutch without any substantial power loss whereas a back load to be transmitted from the driving wheel to the engine in excess of a predetermined value is interrupted by the disconnection of the one-way clutch and the slipping of the friction clutch to prevent the engine from being subjected to any ...

... 1,003,283. Friction clutches. B. HIRANO. Nov. 3, 1961 [Dec. 3, 1960], No. 39393/61. Heading F2L. The pressure engaging a centrifugally or manually-controlled friction clutch in a motor cycle &c. is reduced as the transmitted torque increases, by shear forces acting on one or more non-metallic coupling members in the drive path. As shown, a driving shaft 1 is fast with a drum in which are splined discs 4 interleaved with driven clutch discs carried in a drum 6 rotatable about the driving shaft. Axially-directed non-metallic coupling members in the form of rubber rods 11 transmit torque to a driven gear 10. The clutch is engaged by pressure transmitted through a rod 12. Increasing torque causes the rubber rods 11 to turn relatively to the clutch axis, due to the shear forces developed, and thus reduces the clutch-engaging pressure.

Selective torque clipping mechanism

A torque clipping mechanism embodying the concepts of the present invention is adapted to obviate torque spikes from being imparted to the transmission of a vehicle by the crankshaft of an engine during the start-up and shut-down procedures for that engine. The torque clipping mechanism operates in conjunction with a torque transfer device that is operatively connected between the crankshaft, which delivers torque from the engine, and the rotatable input shaft of a vehicular transmission. A spring is employed to effect the application of the torque transfer device, but the spring allows slippage of the torque transfer device upon the application of a predetermined torsional force to the torque transfer device. Hydraulic fluid acting under centrifugal force is employed to preclude slippage when the rotational speed of the power output shaft exceeds a predetermined rate.

Improvements in or relating to couplings for transmitting torques

551,892. Slipping-clutches. SULZER FRERES SOC. ANON. Sept. 11, 1941, No. 11638. Convention date, Nov. 8, 1940. [Class 80 (ii)] A clutch which slips upon overload comprises friction plates 8 splined to a drum 6 fixed to a gear wheel 2 and co-acting friction plates 5 splined to a spider 4, the plates 5, 8 being pressed together by annular members 10 under the action of springs 11. A pair of axially movable concentric rings A, B engage one another by inclined teeth 13, 14 and are splined to a hub 3 on a shaft 1 and to the spider 4 respectively by teeth 17 .. 20. In operation, torque is transmitted to the spider 4 from the shaft 1 through the rings A, B which, due to the inclined teeth 13, 14, tend to separate the annular members 10. If the torque exceeds a predetermined amount the members 10 move apart and the clutch plates 5, 8 slip. To prevent overheating of the parts easily fusible material 9 is inserted between some of the plates 5, or the friction surfaces may be of such material. Heating up of the dutch then causes the fusible material to be melted and discharged whereupon the annular members 10 are pressed against the side faces of the spider 4, the clearance between the clutch members being great enough, due to the escape of the fusible material, to prevent further clutch engagement. Instead of an easily fusible material a material which breaks up into small particles upon a rise of temperature may be used. The teeth 13, 14 may be axial and the teeth 17 ... 20 inclined.

Torque limiting shaft and sprocket assembly

A driveline component with a first drive member, which is rotatable about an axis, a second drive member and a clutch. The second drive member has a hub, which is supported on the first drive member for rotation about the axis, and a transmission portion. The transmission portion, which is configured to engage a flexible power transmitting member, is disposed about the hub and aligned to a transmission axis that is generally perpendicular to the axis. The clutch has a spring and a set of interleaved clutch plates having portions that are coupled for rotation with a respective one of the first drive member and the second drive member. The spring generates a force that is transmitted through the hub such that the clutch plates frictionally engage one another. The location of the transmission portion relative to the transmission axis is unaffected by wearing of the set of clutch plates.

Slip clutch

A slip clutch acts between a shaft and a housing. The slip clutch includes an oil reservoir within the housing and one or more slipping surfaces disposed in the oil reservoir that are keyed to the shaft and possibly alternately to the housing. The slipping surfaces may include stacked plates or washers. Each of the washers includes an oil groove or other structure on one surface thereof that maintains a consistent film of oil on the washer surfaces. The stacked washers slip relative to one another such that the shaft rotates relative to the housing upon an application of torque that exceeds a predetermined torque.

Power transmission system for snow-removing machine

A power transmission system wherein drive power is transmitted from a drive source to an auger transmission for rotating an auger, and a snow blower is provided. An overload protecting mechanism is located between the snow blower and the auger transmission, thereby absorbing overload to be exerted on a power delivery path between the drive shaft and the auger transmission. Thus, snow-removing operation is not interrupted even when the power delivery path encounters overload. The overload protecting mechanism may comprise, for example, either a friction coupling employing a plurality of friction plates or a rubber coupling employing cushion rubbers. The overload protecting mechanism is located in a large space between the auger transmission and the snow blower, allowing existing space to be effectively utilized.
