摘要： A traction servomotor (74) for supplying a control valve (66) with an operational input independently of an operator pedal assembly (16) in response to a signal supplied to a controller (116) indicating a different rotational spin of the wheels of a vehicle. The traction servomotor (74) has a housing (80) with an input rod (76) with a first section retained in axial openings in the housing and a second section is pivotally connected to the operator pedal assembly (16). The interior of the housing (80) is divided by a diaphragm (96) which is attached to the first portion of the input rod (76). The controller (116) is connected to the housing (80) such that in a first mode of operation wherein the activation of the control valve (66) is dependent on an input from the operator pedal assembly (16) a first fluid pressure is presented to both sides of the diaphragm (96) and in a second mode of operation, a second fluid pressure is presented to one side of the diaphragm (96) to create an actuation pressure differential. The actuation pressure differential acts on and moves the input rod (76) to activate the control valve (66). Activation of the contral valve (66) allows an operational pressure differential to be created in a brake booster (12) and an ECU (34) thereafter selectively controls the communication of pressurized fluid to the driving wheels to effect a brake application in the wheels and absorb some driving torque to synchronize the rotational spin of the wheels.
