摘要： A centrifugal clutch mechanism couples a first driven element to a drive element for rotary torque transmission at a first speed range from a rotary drive source to a load when the rotation of the drive source is lower than a predetermined reference speed. The centrifugal clutch mechanism includes a double-arm coupling lever pivoted to the drive element, a clutch pad or shoe pivoted to one end of the coupling lever and having a surface engagable with an inner surface of the first driven element, and a pair of centrifugal weights carried on the other end of the coupling lever. At least one flat spring is yieldably fastened to the weight or to a stop rigid on the drive element to be frictionally engaged by the stop or the weight, thereby resisting frictional oscillation of the clutch shoe on the coupling lever during a transition range between completely coupled and completely uncoupled mode of operation of the centrifugal clutch. The flat spring or springs may be so arranged as to be engaged by the coupling lever proper. A second driven element is coupled to the drive element by a one way clutch mechanism for rotary torque transmission at a second speed range, at which time the centrifugal clutch will be uncoupled.

摘要： An automatic transmission system has a controllor for controlling the slip rate of a clutch in accordance with the amount of depression of an accelerator pedal instead of controlling the ON/OFF condition of the clutch by a control signal when it is discriminated that the gear change position of a transmission and the amount of depression of the accelerator pedal are in the predetermined states. In a predetermined condition, the slip rate of the clutch is adjusted in accordance with the amount of depression of the accelerator pedal so as to put the clutch in a semi-engaged condition, thereby enabling the speed of the vehicle to be controlled within a very low speed range simply by operation of the accelerator pedal.

摘要： A differential device includes a pair of propeller shafts extending into a housing, a pair of side gears connected respectively to the propeller shafts, and at least one pair of element gears having screw gear portions meshing respectively with screw gear portions of the side gears. The element gears have respective coupling gear portions meshing with each other. In order to improve a drive torque distribution, either pitch diameters or helix angles of the screw gear portions of the two side gears are different from each other. In order to reduce the overall diameter of the differential device, a spline portion and the screw gear portion of at least one of the two side gears are spaced from each other along an axis of the side gear, the spline portion serving to connect the side gear to the mating propeller shaft.

摘要： Input and output members (19), (28) and a clutch disc (32) are coaxially rotatable relative to each other, the clutch disc (32) being frictionally engageable with the input member (19). A coil-would spring (33) is wound around the input member (19) and connected at its ends to the clutch disc (32) and output member (28). An electromagnetic coil (26) may be energized to attract the clutch disc (32) into frictional engagement with the input member (19), causing the coil-wound spring (33) to tightly wind around the input member (19) and drivably connect the input member (19) to the output member (28). A spring (41) quickly and smoothly disengages the clutch disc (32) from the input member (19) when the coil (26) is de-energized. A plurality of pins (36) extending through the clutch disc (32) ensure parallel movement of the clutch disc (32) toward and away from the input member (19). The spring (41) is in the form of an annular plate spring and is resiliently flexed by means of hard rivets (43) projecting from a cover (34). The spring (41) slides on the rivets (43) during engagement and disengagement of the clutch disc (32), thereby minimizing friction and abrasion.

摘要： A parallel-axis gear differential includes pairs of element gears (34) mounted within pockets (36) formed in a differential housing (10). Each element gear includes a first gear section (38) for meshing with one of two side gears (30 or 32), a second gear section (40) for meshing with the first gear section of its mating element gear, and a stem section (42) for interconnecting the first two gear sections. Associated with each pair of pockets are two passageways (44, 46) for providing respective paths for the flow of lubrication fluid between the exterior of the housing and the respective meshing gear sections (38, 40) of each pair of element gears (34). Further, the shape of each pair of pockets (36) is modified between its apron portions (a) and its opening (b) to increase the space between the pocket and the mating surfaces of the element gears. This increased space at the pocket opening allows a greater volume of lubricating fluid to be moved by the rotating teeth of element gears, reducing the fluid pressure between the interior portion of the pockets and the surface of the element gears, and thereby increasing the flow of lubricating fluid to facilitate lubrication.

摘要： Input and output member (21), (28) and a clutch disc (32) are coaxially rotatable relative to each other, the clutch disc (32) being frictionally engageable with the input member (21). A coil-wound spring (33) is wound around the input member (21) and connected at its ends to the clutch disc (32) and output member (28). An electromagnetic coil (26) may be energized to attract the clutch disc (32) into frictional engagement with the input member (21), causing the coil-wound spring (33) to tightly wind around the input member (21) and drivably connect the input member (21) to the output member (28). A generally tubular cover (34) surrounds the coil-wound spring (33), the spring means (40) moving the clutch disc (32) toward engagement with the cover (34) when the coil (26) is de-energized. A resilient, non-magnetic spacer (51) is fixed to the clutch disc (32) between the clutch disc (32) and the cover (34) which serves the dual function of absorbing vibration and preventing ohmic engagement of the clutch disc (32) with the cover (34) which would cause leakage of magnetic flux and failure of the coil (26) to engage the clutch (11) when the clutch disc (32) becomes worn.

摘要： In a vehicle clutch control apparatus having an actuator for operating a friction clutch and a controller for controlling the actuator, whereby a first data representing a semi-engaging zone is obtained by the controller just after the engine is started and the vehicle is driven to move, the apparatus has a data generator for producing a second data relating to the magnitude of the load of the vehicle and a unit for correcting the first data in accordance with the second data. As a result, data representing the actual semi-engaging zone of the clutch depending upon the load conditions of the vehicle at that time can be obtained, so that it becomes possible to realize an appropriate semi-engaging operation even when the load of the vehicle has changed.
