Actuator for braking control of car, has braking assistance device including cam driven in rotation by motor and roller in sliding contact with cam to be driven in translation by rotation of cam and cause movement of actuating arm

摘要

The actuator has an actuating arm (1) mechanically connected to a brake pedal for transmitting a braking force (2) exerted by a driver of a vehicle on the brake pedal. A braking assistance device includes a cam (52) driven in rotation by a motor (3) and a roller (42) in sliding contact with the cam to be driven in translation by the rotation of the cam and cause movement of the actuating arm according to increasing braking force during the depression of the pedal brake by the driver.
