Problems solved by technology

[0007] However, even if the housing is provided with a sealing member for relieving the impact sound, when the pedaling force of the brake pedal is released, the rattling noise may occur since the shock load may not be completely eliminated
[0008] In addition, although the plurality of rubber dampers provided in the pedal simulator has a high contribution to the characteristic according to hysteresis during pressurization of the brake pedal, since the plurality of rubber dampers have a small hysteresis characteristics, so may reduce pedal feel

Abstract

Disclosed are a friction member and a master cylinder comprising same of the present invention. According to one aspect of the present invention, a master cylinder may be provided, comprising: a cylinder body having a bore formed therein; a piston provided to be retractable in the bore and provided to have a portion protruding from the cylinder body; a housing provided to surround the protruding portion of the piston and having a through hole formed therein so as to allow insertion of an input rod connected to a brake pedal for pressurizing the piston; a friction member, provided between the housing and the piston, for increasing a frictional force with the piston when the piston extends and retracts; and a pedal simulator, connected to the piston, for providing a repulsive force to the brake pedal.

Description

technical field [0001] The present disclosure relates to a friction member and a master cylinder including the same, and more particularly, to a friction member capable of improving pedal feel and reducing noise during operation of a brake pedal and a master cylinder including the same. Background technique [0002] Generally, a vehicle is provided with a brake actuator unit (BAU) for electronically controlling brake hydraulic pressure delivered to caliper brakes mounted on each wheel. [0003] The brake actuator unit includes a master cylinder for generating hydraulic pressure, a reservoir for supplying oil to the master cylinder, a valve block for controlling flow of hydraulic pressure generated from the master cylinder, and An electronic control unit (ECU) that electronically controls the valve block. This brake actuator unit is installed on the vehicle and performs braking action by supplying hydraulic pressure to the caliper brakes installed on each wheel. [0004] Th...
