INDEPENDENT SUSPENSION AXLE TYPE DIFFERENTIAL HAVING A RIGID AXLE TYPE DIFFERENTIAL FUNCTION AND METHOD CONTROLLING THE DIFFERENTIAL

摘要

Independent suspension axle differential type having a rigid axle type differential function according to the present invention is to seek to improve the off-road riding comfort and smooth by selecting the rigid axle or axle independent suspension type, as needed; First and second constant-speed driving force to the rear wheel (23, 25) a joint (27, 29) to the rear driving system of the rear-wheel and four-wheel drive vehicle for transmitting the first and second constant-velocity joint provided on both sides of the differential 21 27 and 29 the first and second constant-velocity joint (27, 29) for selectively rigid axle type with independent suspension selected to be operated by the driver so as to realize the axle-type switches 31, a selection switch to limit the vertical oscillation of the of the rigid axle type, or independent suspension is driven or stopped in accordance with the selection operation of the axle-type hydraulic pump 33 to the hydraulic pressure generated fed or discharged, the hydraulic pump is operated expansion by hydraulic pressure supplied from the (33) first and second a constant-velocity joint (27, 29) opposite thereto and two sides of the differential housing 39 so as to bind the upper and lower swing the first and second constant-velocity joint (27, 29), first and second hydraulic cylinders (35, 37) is located between the It consists of a.
