VARIABLE PEDAL FEELING ADJUSTMENT DEVICE

摘要

Disclosed is a variable pedal feeling adjustment device. A pedal simulator includes a simulator block formed with an oil hole connected to a master cylinder through a passage and a bore communicating with the oil hole, a damping housing slidably installed in the bore while being restricted in rotation, a first reaction unit provided in the bore and configured to provide reaction force by being pressurized by oil from the master cylinder, and a second reaction unit supported by the damping housing and configured to provide reaction force by being pressurized by the first reaction unit. An auxiliary simulator includes an auxiliary chamber connected to the passage through a connection passage, an auxiliary piston slidably provided in the auxiliary chamber, and an auxiliary spring to elastically support the auxiliary piston. A control valve is installed to the connection passage to control transfer of hydraulic pressure to the auxiliary chamber.

1. A variable pedal feeling adjustment device to adjust a pedal feeling provided for a driver by hydraulic pressure caused by pedal effort of a driver, comprising:
a pedal simulator including a simulator block formed with an oil hole at an upper portion thereof and a bore therein, the oil hole being connected to a master cylinder through a passage to receive hydraulic pressure caused by pedal effort of a driver and the bore communicating with the oil hole, a damping housing slidably installed to a lower portion of the bore to seal a lower end portion of the bore while being restricted in rotation, a first reaction unit provided in the bore and configured to provide reaction force by being pressurized by oil supplied from the master cylinder, and a second reaction unit supported by the damping housing and configured to provide reaction force by being compressed by pressurization of the first reaction unit; an auxiliary simulator including an auxiliary chamber connected to the passage through a connection passage, an auxiliary piston slidably provided in the auxiliary chamber, and an auxiliary spring to elastically support the auxiliary piston; and a control valve installed to the connection passage to control transfer of hydraulic pressure to the auxiliary chamber.
