Brake hydraulic control actuator for vehicles
This brake hydraulic control actuator increases ability to reserve the leaked brake fluid and degree of freedom for the structural layout in the actuator body. The bottom surface of the actuator body ( 10 ) having the cylinder bores ( 43 ) of the low pressure reservoirs ( 40 ) and ( 41 ) thereon is closed and sealed by the pot plate ( 20 ), and the pocket ( 23 ), which projects toward the direction to depart from the bottom surface, is formed in the pot plate ( 20 ).
1. A brake hydraulic control actuator for a vehicle comprising:
an actuator body which has a solenoid valve installed in a hydraulic channel between a brake master cylinder and a wheel brake so as to control brake fluid flowing in and out said wheel brake, low pressure reservoirs which reserve the brake fluid flown from the wheel brake through said solenoid valve, a pump which returns the brake fluid within the pressure reservoirs to said hydraulic channel, and a motor which drives said pump;
a brake fluid leakage outlet hole formed between an pump interior and a bottom surface of an actuator body;
a pot plate which closes said bottom surface of the actuator body having cylinder bores for the low pressure reservoirs; and
a pocket formed on said pot plate projecting toward a direction to be apart from the bottom surface of the actuator body.
2. The brake hydraulic control actuator for a vehicle according to claim 1 , wherein:
said pot plate has plural brackets therearound, and said brackets have rubber mounts.
3. The brake hydraulic control actuator for a vehicle according to claim 2 , wherein:
said rubber mounts comprises a doughnut rubber and an inner bolt installed in a central region of a vibration isolation rubber.
