Abstract
An electromotive brake system may include a caliper housing, a first and second friction pads, a brake disk disposed in between, a pressurizing member connected to the second friction pad, a push rod with a push rod groove, an operating disk inserted in the push rod groove, first and second springs, a rotating ramp adapted to convert the rotational movement of a motor into a linear movement of a non-rotating ramp by a ball disposed between the rotating ramp and the non-rotating ramp. The electromotive brake system may further include first and second catching portions, a plurality of teeth and corresponding engaging protrusion of the teeth. The plurality of teeth and the protrusion may have slanted or curved surfaces.
Claims14
An electromotive brake system comprising:
- a caliper housing with a housing groove and a mounting recess;
- a first friction pad fixed to the housing groove of said caliper housing;
- a second friction pad adapted to move toward the first friction pad;
- a brake disk disposed between the first friction pad and the second friction pad;
- a pressurizing member operably connected to the second friction pad and formed with screw threads in an interior circumference of a rear end portion of said pressurizing member;
- a push rod having a threaded front end portion engaging with the screw threads of said pressurizing member and formed with a push rod groove being concave toward a front end of said push rod and at an inner circumference of a rear end portion of said push rod;
- an operating disk inserted in the push rod groove and adapted to selectively rotate the push rod to selectively move the pressurizing member forward with respect to the push rod;
- a non-rotating ramp adapted to exert force on the push rod so as to move the push rod forward;
- a first spring adapted to apply force against the force of the non-rotating ramp to the push rod;
- a rotating ramp mounted in the mounting recess of said caliper housing;
- and
- a ball disposed between the rotating ramp and the non-rotating ramp.
