REGENERATIVE BRAKE CONTROL BOOSTER CAPABLE OF INCREASING THE RESPONSE RATE OF REGENERATIVE BRAKING FORCE IN PANIC BRAKING

摘要

PURPOSE: A regenerative brake control booster is provided to heighten the response rate of a brake by generating differential pressure for high pressure in case of panic braking. ;CONSTITUTION: A regenerative brake control booster comprises a casing coupled with a front cell and a rear cell hermetically, a diaphragm and a power piston dividing the casing into a constant pressure chamber and a transformation chamber, a valve housing(120) coupled with the rear cell hermetically and provided with a housing space(121) on the inside in the longitudinal direction, an input shaft(140) receiving pressure force from a brake pedal, a control plunger(150) having multistage steps and connected with the input shaft to form pedal force on the brake pedal, a valve body(130) installed to the housing space of the valve housing and attached with the input shaft and the control plunger, an output shaft(160) connected with the control plunger to transfer force to a master cylinder, a poppet valve(180) opening and closing an inside space(131) of the valve body according to the operation of the input shaft, a silencer(136) reducing noise of air influent to the inside space of the valve body, and a filter(137) removing dust contained in the influent air, wherein a slot(145) is formed in the input shaft to make partial air flow in the transformation chamber directly without passing through the silencer and the filter when air flows in the valve body.;COPYRIGHT KIPO 2011
