Abstract
A pedal simulator is disclosed. The pedal simulator according to an embodiment may include a cylinder of which a side is connected to a reservoir storing a pressing medium and another side is connected to a wheel cylinder, the cylinder including an internal space in which the pressing medium is stored, and a piston of which a portion is movable back and forth by a brake pedal inside the cylinder, the piston configured to provide a reaction force corresponding to a pedal effort of the brake pedal while moving back and forth and discharge the pressing medium stored in the internal space of the cylinder toward the wheel cylinder.
Claims20
A pedal simulator comprising:
- a cylinder of which a side is connected to a reservoir storing a pressing medium and another side is connected to a wheel cylinder, the cylinder including an internal space in which the pressing medium is stored;
- and
- a piston of which a portion is movable back and forth by a brake pedal inside the cylinder, the piston configured to provide a reaction force corresponding to a pedal effort of the brake pedal while moving back and forth and discharge the pressing medium stored in the internal space of the cylinder toward the wheel cylinder,
- wherein the piston comprises:
- a push rod connected to the brake pedal;
- a first flange provided at an end to which the push rod is coupled;
- and
- a second flange provided at another end positioned inside the cylinder,
- wherein the cylinder further comprises a feeling damper configured to be compressible according to a back-and-forth movement of the piston,
- wherein the feeling damper comprises a feeling damper housing configured to fix the feeling damper to the cylinder, and
- wherein the feeling damper housing comprises a feeling damper inserting groove which an end of the feeling damper is inserted in and fixed to;
- and a fixing member coupled to the cylinder.
