摘要： A transmission for a four-wheel drive vehicle having a multi-speed geartrain (42) and power transfer mechanism (44) incorporated into a common housing assembly (45). The multi-speed geartrain includes a input shaft (46), a mainshaft (48), and a plurality of constant-mesh gearsets arranged for selectively coupling the mainshaft (48) to the input shaft (46) for driven rotation at various speed ratios. The mainshaft (48) can be selectively coupled to the power transfer mechanism (44) for establishing two alternative power transmission routes. In particular, a range shift mechanism (58) is provided for establishing a high-range power transmission route and a low-range power transmission route from the mainshaft (48) to the input of an interaxle differential (60). The torque delivered to the interaxle differential (60) is split between the front (32) and rear (38) drivelines to establish a full-time four-wheel drive mode. As an option, a transfer clutch (200) is provided for automatically controlling slip and torque biasing between the outputs of the interaxle differential (60). A lock-out clutch (184) is provided for permitting the interaxle differential (60) to be locked for establishing a locked four-wheel drive mode. As a further option, a mode clutch can be provided for permitting one of the drivelines to be selectively disconnected from the transmission for establishing a two-wheel drive mode.

摘要： A clutch assembly for automotive vehicle four-wheel drives either in association with an axle disconnect or wheel hub incorporates a power shift mechanism (40) which can be remotely activated either when the vehicle is static, in motion and during either forward or reverse direction of movement to positively drive clutch members (22,30) into and out of engagement with one another. The power shift mechanism (40) includes sealed envelopes in the form of expandable and contractable compartments (44,44′) which in response to a remote control valve will positively shift the clutch members (22,30) into and out of engagement, and the members will remain in the shifted position without the continued application of force until positively shifted away from that position by the power shift mechanism (40).

摘要： To achieve a balance between ensuring four-wheel drive performance during re-acceleration and reducing friction in a drive transmission system during braking when the foot is lifted off an accelerator in a low-speed region when the connected, four-wheel drive mode has been selected. The system for transmitting drive force to the left and right rear wheels (19, 20) comprises a dog clutch (8) and an electronically controlled coupling (16); a 4WD control unit (34) is provided, which controls the engagement and disengagement of the dog clutch (8) and the engagement and disengagement of the electronically controlled coupling (16). In this clutch control device for a four-wheel drive hybrid vehicle, the four-wheel drive hybrid vehicle includes a "disconnected, two-wheel drive mode" and a "connected, four-wheel drive mode." When the foot is lifted off an accelerator in a low-speed region when the "connected, four-wheel drive mode" is selected, the 4WD control unit (34) maintains the "connected, four-wheel drive mode" while the brakes are not depressed, and shifts the mode to the "disconnected, two-wheel drive mode" when the brakes are depressed.
