Abstract: A transmission compounder assembly comprising an input shaft, an output shaft and a one-way clutch operable to establish a direct-ratio drive path between the shafts. A planetary gearset can be selectively engaged to establish a compound-ratio drive path between the shafts. The planetary gearset includes a sun gear, a ring gear fixed to the output shaft, a carrier fixed to the input shaft, and a plurality of planet gears rotatably supported from the carrier and meshed with both the ring gear and the sun gear. A band brake is provided for selectively braking the sun gear. A clutch pack is mounted between the carrier and the sun gear and can be selectively actuated to prevent relative rotation therebetween. The compounder assembly further includes a brake actuator for controlling actuation of the band brake and a clutch actuator for controlling actuation of the clutch pack.

Abstract: A strut for mechanically coupling a driving member to a driven member in a planar one-way clutch is formed in a progressive die from a length of cold-formed metallic stock material such that the strut's diametrical member-engaging end surfaces are coextensive with a pair of cold-formed surfaces of the stock material. A pair of oppositely-projecting "ears" are integrally formed on the strut proximate to one of its end surfaces at one station of the progressive die. The ears cooperate with a complementary recess or pocket formed in one member's planar clutch face to thereby nominally position and maintain the strut's first end surface within the pocket. A surface on each ear is preferably coined at another station of the progressive die to thereby provide a relief which prevents deleterious contact between the ears and the opposed clutch face of the other clutch member.

The first annular cam member is rotatably fixed with respect to the pressure plate. The second annular cam member is rotatable relative to the first annular cam member and has a plurality of second ramped cam surfaces in engagement with the first ramped cam surfaces. The second annular cam member, together with the first annular cam member defines an effective pressure plate thickness relative to the engagement surface. The cam spring is connected with the cam member and rotatably biases the cam members toward an increased cam height.

The bearing housing also includes a pair of spaced gear mounts for supporting the ends of the worm shaft and a worm gear disposed for rotation around a vertical axis. A motor is provided for rotating the worm shaft, the worm being arranged in driving relation with the worm gear. A sleeve is mounted at each end of the worm shaft for movement with the worm shaft in response to longitudinal forces transferred back from the worm gear to the worm.

Abstract: An acceleration sensitive double overrunning clutch is directionally preset by a change in speed, i.e., acceleration, rather than relative rotation. The clutch is especially adapted for use in power transmission devices such as motor vehicle transfer cases. The clutch includes a plurality of rollers disposed in a like plurality of spaces having symmetrically arranged oblique walls formed by adjacent portions of an inner member and a concentric outer member. The rollers are arranged within a spacing cage which is coupled to an annular weight. A speed change, i.e., acceleration or deceleration, shifts the weight and presets the cage and rollers to function in their engaged or overrunning modes in one direction or the other depending upon the direction of such acceleration.

Abstract: A change-speed transmission in the power train of a motor vehicle has a planetary gearing and coaxial radially inner and outer disc clutches, namely a direct clutch and a reverse clutch. At least that clutch which is engaged (i.e., in use) is cooled by a lubricant for the planetary gearing, and the flow of coolant to the clutches is regulated by the axially movable pressure plate of one of the clutches. A jet pump conveys lubricant from the sump in the transmission case into an axially extending channel of the input shaft of the transmission, and such channel forms part of a system of passages which supply coolant at least to that clutch which is then in use to transmit torque from the input shaft to an output element of the transmission.

Abstract: A friction clutch for a motor vehicle includes a cover, a pressure plate, a biasing member and an adjustment mechanism. The adjustment mechanism includes a first annular cam, a second annular cam and a torsional spring and housing assembly. The cover has an axis of rotation. The pressure plate is coupled to the cover for rotation therewith about the axis. The pressure plate has a frictional engagement surface substantially normal to the axis. The biasing member is interposed between the cover and the pressure plate, and biases the pressure plate toward an engaged pressure plate position. The adjustment mechanism is centered about the axis and is located at a first radial distance from the axis. The adjustment mechanism is operably disposed between the biasing member and one of the pressure plate and the cover. The first annular cam is rotatably fixed with respect to the pressure plate and the cover. The second annular cam is rotatable relative to the first annular cam.

Abstract: A hydrokinetic torque converter includes an impeller cover and a bypass clutch. A drive ring is located between adjacent surfaces of the cover and a clutch piston, which moves axially on a support surface. The piston is welded at a radially outer position to thin clutch plate, which is supported at another radial location on the cover. As the piston moves into engagement with the ring and cover, the clutch plate permits this movement by bending elastically. When clutch apply pressure is reduced, energy stored in the clutch plate is used to move the piston out of engagement with the drive ring and cover.

Abstract: For a CVT it is proposed to determine an operating point from the number of revolutions of the primary disc (12) and the number of revolutions of the secondary disc (13). The operating point is assigned to a first characteristic field which has ranges of unauthorized ratios and one range of authorized ratio. If an error occurs, the pressure level in the adjustment area of the secondary disc (pSEK) is increased in a first step. If the error continues an emergency program is activated in a second step.

Left and right electromagnetic clutches connected to the clutch drive shaft are accommodated in left and right side casings. Oil for lubricating the electromagnetic clutches is supplied from an oil pump accommodated in the center casings and driven by the clutch drive shaft through oil passages and axially defied in the clutch drive shaft and left and right output shafts. Thus, the length of the oil passages for supplying the oil from the oil pump to the clutches can be minimized to provide a reduction in size of the power transmitting system.

Abstract: A driving connection is provided for torque transmission in the drive train of a motor vehicle for releasable connection of a crankshaft with a coaxial hydrodynamic torque converter.

Abstract: A ring gear support member is supported radially immovably on the outer circumference of an input shaft through a ball bearing. A brake hub of a reverse brake, as supported by the ring gear support member, is made movable in the circumferential direction relative to the ring gear support member and is urged to a center position by a coil spring. When the reverse brake is applied to couple the ring gear support member unrotatably to a casing, the brake hub is supported through the coil spring by the ring gear support member. As a result, the meshing vibration, as generated at the meshing portion between pinions and a ring gear, can be prevented from being transmitted to the casing through the brake hub, thereby reducing noise.
