    摘要： A power steering and limited slip differential system is provided with a main booster (14) generating a steering effort for front wheels (121, 122), a directional control valve (16) having a pair of reaction chambers (56, 57) and a friction clutch (26) disposed between a differential gear mechanism (25) and a driving wheel axle (119) for rear wheels (123, 124) and is further added with an auxiliary booster (15) generating a compensation steering effort for the front wheels (121, 122) and a clutch control air cylinder (27) for coupling and decoupling the friction clutch (26).
    In the system, an injection pressure control valve (18, 19) injects compensating pressure oil into the auxiliary booster (15) and the reaction chambers (56, 57) of the directional control valve (16) in response to a vehicle speed and steering effort at the beginning of steering and steering back and concurrently controls the pressure of the injected compensating pressure oil, and a air pressure control valve (28) charges and discharges operating compressed air to and from the clutch control air cylinder (27) in response to the vehicle speed and the steering angle of the front wheels (121, 122), and further in response to the slipping at one side and the both sides of the rear wheels (123, 124) and thereby controls the air pressure of the clutch control air cylinder (27).
