摘要： A supplemental pressurized hydraulic supply (103) provides control of a hydraulic coupling (32a,32b,32c) that normally operates in response to differential rotation between a pair of rotary members (26,28) to provide actuation of a clutch (68) that couples the pair of rotary members. A rotary seal assembly (104) of the supply (103) feeds pressurized hydraulic fluid to the coupling to provide supplemental actuation of the clutch (68) that is normally actuated by hydraulic fluid from a hydraulic pump (48) that operates in response to the differential rotation between the pair of rotary members. In one embodiment, the hydraulic coupling (32a) also includes a differential gear set (36). A further embodiment of the hydraulic coupling (32b) includes a clutch (68) having a pair of clutch packs (69) that can be individually actuated by the supplement pressurized hydraulic fluid supply (103). A further embodiment of the hydraulic coupling (32c) has a pair of rotary members embodied by an annular gear (26) and a rotary member (28) extending completely through the coupling.

摘要： A modulating clutch for disposition and use in a motor vehicle drive train includes a disc pack clutch assembly and clutch actuator. The clutch actuator includes an assembly for generating compressive force which is applied to the clutch pack assembly and a preload member which partially engages the clutch pack to provide torque transfer up to a predetermined level without activation of the clutch actuator. Activation of the clutch actuator increases the torque transfer or throughput above the predetermined level. The differential of the present invention thus functions passively as a limited slip differential by allowing torques in excess of the predetermined torque level to slip each axle relative to the driveline input thereby provide a constant, minimum level torque coupling between the driveline and each axle. When the clutch actuator is energized, it may be utilized to control torque transfer at levels above the predetermined level between the input and output of the clutch mechanism. The modulating clutch of the present invention has application in vehicle differentials.

摘要： A four wheel drive system of a vehicle has a transfer clutch capable of varying clutch torque transmitted therethrough from an engine to front wheels. The clutch torque is controlled by a driving force distribution control unit in accordance with a front and rear wheel speed difference determined from signals from front and rear wheel speed sensors. Preferably, the control unit controls a distribution ratio of a front wheel driving force to a rear wheel driving force by controlling the clutch torque of the transfer clutch in such a manner that the distribution ratio decreases as the wheel speed difference increases when the wheel speed difference is positive, that is the front wheel speed is higher than the rear wheel speed, and that the distribution ratio increases as the absolute value of the wheel speed difference increases when the wheel speed difference is negative.

摘要： A motor vehicle four-wheel-drive transmission employs an interwheel differential gear in a first axle, and solely viscous fluid coupling device in a second axle for differential transmission of drive to the road wheels of the second axle only when a speed-difference is established between the first and second road wheels, the two axles being mutually in direct driving connection through respective propeller shafts commonly driven by a change-speed box. In one arrangement of axle with a viscous fluid coupling device, a crown wheel is mounted co-axially on a housing of such coupling device from which nearside and offside half-shafts extend driven by separate sets of "inner" annular plates interleaved with those of an "outer" set of annular plates driven by the housing. In another similar arrangement, two separate viscous fluid couplings are used, the housings thereof being driven by a common crown wheel.

摘要： The disclosure relates to a steering system useful for providing stable control during rear axle steering of harvesters, such as self-propelled windrowers. The steering system utilizes left and right-hand side drive motors, and allows for hydraulic fluid to flow between the left and right-hand side drive motors through crossover lines to regulate a speed differential between wheels when the steering system is actuated into a rear axle steering operation mode.

摘要： A torque distribution control device includes two rotational speed differential responsive type control couplings each having various transfer torque characteristics which differ in the ratio of a transfer torque to a rotational speed differential. The control device selects one of the torque transfer characteristics in response to a signal supplied thereto. When turning the outer wheel side control coupling is supplied with a signal for selecting the transfer torque characteristic that produces a maximum transfer torque for a given rotational speed differential, and the inner wheel side control coupling is supplied with a signal for attaining a non-slip rotational speed differential and for selecting the transfer torque characteristic that produces a transfer torque equal to that produced by the outer wheel side control coupling when the non-slip rotational speed differential is obtained. When the vehicle is running straight ahead, both control couplings are supplied with signals for selecting the transfer torque characteristics that produce maximum transfer torque for a given rotational speed differential.
