TRACTION CONTROL MODULATOR |
摘要 |
G-4371 C-4371 TRACTION CONTROL MODULATOR A vehicle braking actuated traction control system is provided which includes a bored frame fluidly connected with a master cylinder and a wheel brake. A spring biased plunger with a sealing head slidably mounted within the bore isolates the bore from the master cylinder by axial movement of the plunger in a first direction. A piston operatively associated with the plunger is sealably slidably mounted within the bore for creating a variable control volume in the bore in fluid communication with the wheel brake. The piston is connected with the plunger via a spring which biases the plunger away from the piston. A nut is fixably connected with the piston and a drive screw threadably engaged with the piston is reversibly powered by an electric motor which is responsive to the signals given by a controller which is cognizant of avehicle wheel condition. Upon the appropriate signal, the drive screw will power the piston to a position to cause the plunger to isolate the wheel brake from the master cylinder and thereafter modulate the pressure within the wheel brake as commanded by the controller during a traction control cycle.
