摘要: A center differential (17) including a clutch pack (33), a cam ramp actuator (31) for moving the friction discs (65,67) toward an engaged position, and a viscous coupling (29) which will have a “slip speed” representative of the speed difference between the front (11) and rear (23) wheels. There is a one-way clutch (57) disposed between the output (49) of the viscous coupling (29) and the first ramp plate (51) to transmit positive torque when the vehicle is in a forward gear, but negative torque is not transmitted, for example, during braking. An override mechanism (55) is provided, including a plurality of spring biased pins (107), such that, below a predetermined speed of rotation, positive torque can also be transmitted when the vehicle is in reverse gear. The pins (107) are associated with flyweight members (97) so that, above the predetermined speed, the pins are disengaged, and positive torque can be transmitted only in forward gear.

摘要: A differential device (17) for use in a four wheel drive system, the device including a viscous coupling (29), a ball ramp actuator (31), and a clutch pack (33). Under normal driving conditions, most of the torque is transmitted to the front drive wheels (11), and the device (17) rotates as a unit. If the front wheels (11) begin to slip, the input shaft (15) and input coupling member (35) rotate faster than the output coupling member (43), thus transmitting torque to the output coupling member (43). This torque is transmitted to the first ramp plate (51) of the ball ramp actuator (31), displacing the actuator from its neutral position (FIG. 3), such that the second ramp plate (52) begins to load the clutch pack (33) and transmit torque from the housing (25) to the output shaft (19), and from there to the rear drive wheels (23). The device (17) includes a housing (25) which preferably comprises a unitary member having a plurality of axially-extending grooves (77) which receive mating ridges (79) on the outer surface of the input coupling member (35), and ears (81) on the outer friction discs (65). Rollovers (76,83) at opposite ends of the housing retain the various components, thus providing a simple and inexpensive housing and method of assembly of the device.

摘要: Selectively engagable auxiliary leaf springs (38) for vertically supporting a vehicle chassis (32) on an axle assembly (22) in parallel with main suspension springs (34). Forward and rear ends (38b, 38a) of the auxiliary leaf springs are pivotally attached to the vehicle chassis and the axle assembly, and pivotal movement of the forward ends (38b) is inhibited or prevented by engagement of actuator assemblies (56 or 100 or 170) to engage the auxiliary leaf springs. A control system automatically engages the actuator assemblies in response to load added to the vheicle and/or vehicle steering movement and/or rapid vehicle acceleration.
