Abstract
A brake stroke simulator for achieving good stroke feeling in a vehicular brake apparatus has a first piston being displaceable by receiving a master cylinder pressure, and a second piston disposed so as to form a gap between the second piston and the first piston. A plug is disposed so as to form another gap between the plug and the second piston. A first spring is disposed between the first piston and the second piston so as to urge the pistons away from each other. A second spring is provided for urging the second piston away from the plug. The brake stroke simulator is able to reduce the characteristic variations among individual products.
Claims6
A brake stroke simulator for use with a master cylinder, comprising:
- a first piston displaceable upon receipt of pressure from the master cylinder, the first piston being displaceable over a first distance and a second distance;
- a second piston displaceable with the first piston over the second distance after the first piston has been displaced over the first distance;
- a first spring that urges the first piston away from the second piston;
- a second spring that urges the second piston toward the first piston;
- and
- an elastic member disposed in a contact position between the first piston and the second piston.
