초록 ▼

A brake system actuator which is actuated to increase pressure delivered to a wheel brake through a drive transfer mechanism powered by a variable torque electric motor, the actuator piston being retracted by a substantially constant torque spiral spring which is preloaded to drive transfer means in the opposite direction when the motor is deenergized. This is particularly useful in a brake actuator which is a component of a vehicle wheel brake and wheel anti-lock control system.

대표청구항 ▼

A wheel brake pressure control actuator comprising: a housing having a cylinder bore formed therein, a linearly movable piston reciprocably movable in said bore and defining with one end thereof a variable pressure chamber, an inlet port and an outlet port connected with and communicating with said chamber, said inlet port being adapted to selectively receive brake fluid and introduce same into said chamber, said outlet port being adapted to be in fluid communication with a brake fluid pressure actuatable wheel brake; a variable torque output electric motor having a rotatable drive member, rotatable drive transfer means connected with said drive member and having a linearly movable driven output member connected with said piston, said motor being selectively electrically actuated in one rotary direction to move said piston through said drive transfer means in one linear direction in said bore to decrease the volume of said variable pressure chamber and therefore pressurize brake fluid therein; and a normally preloaded spring connected to said rotatable drive transfer means and continually urging said piston in the other linear direction in said bore tending to increase the volume of said variable pressure chamber and therefore to decrease the brake fluid pressure therein, said spring being further loaded by movement of said piston in the chamber volume decreasing direction and acting through said drive transfer means, upon sufficient electrical deactuation of said motor in said one rotary direction and in concert with any brake fluid pressure in said chamber acting on said piston, to move said piston in the other linear direction in said bore to increase the volume of said variable pressure chamber.
