PEDAL SIMULATOR FOR ACTIVE BRAKE SYSTEM

摘要

Disclosed herein is a pedal simulator for an active brake system. The pedal simulator includes a simulator block provided therein with a bore, a first reaction unit including a first reaction piston slidably installed in the bore, a first damping member installed at the first reaction piston, and a first reaction spring compressed by the first reaction piston, and a second reaction unit including a second reaction piston provided in the bore to support the first reaction spring and slide in the bore, a damping housing connected to the simulator block to be spaced a certain distance apart from the second reaction piston, a second reaction spring installed between the second reaction piston and the damping housing to be compressed by the second reaction piston, and a second damping member installed in the damping housing to contact the second reaction piston.

1. A pedal simulator for an active brake system installed at a master cylinder to receive hydraulic pressure according to a driver's pedal force to provide pedal feel to the driver, the pedal simulator comprising:
a simulator block provided with an oil hole formed at an upper portion thereof to be connected to the master cylinder, and provided therein with a bore to communicate with the oil hole; a damping housing coupled to the bore to seal a lower end of the bore; a first reaction unit provided in the bore and adapted to provide reaction force by being pressed by oil introduced from the master cylinder; a second reaction unit supported by the damping housing and adapted to provide reaction force by being compressed according to pressing of the first reaction unit; and an elastic member provided to the second reaction unit and adapted to provide reaction force by contacting an upper end of the damping housing when the second reaction unit is compressed and moved a certain distance.
