Abstract:
1. 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.
