摘要:
An actuating system 1 for a wheel brake system of a motor vehicle, wherein the braking action is obtained by means of a rotatable cam element 2 fixed to the motor shaft 8 of an electric motor, with said rotatable cam element 2 abutting against an actuating member 4, so as to laterally displace said actuating member 4, resulting in the braking pads 5 being pressed against the friction element or brake disk. Recovery or adjustment of the backlash or gap arising due to the wear of the brake pads. The motor-cam group or assembly is displaced so as to keep the brake pads 5 in light contact with the friction element or disk but without exerting any unwanted braking action.
摘要:
A new actuating system 1 for a wheel brake system of a motor vehicle is proposed according to the present invention, wherein the braking action is obtained by means of a rotatable cam element 2 fixed to the motor shaft 8 of an electric motor, with said rotatable element 2 abutting against an actuating member 4, so as to laterally displace said actuating member 4, resulting in the braking pads 5 being pressed against the friction element (brake disk). Moreover, means are provided according to the present invention allowing to obtain adequate recovery of the backlash arising due to the wear of the brake pads, with these means comprising displaceable slide means adapted to displace the motor-cam group so as to keep the brake pads 5 in light contact with the friction element but without exerting any unwanted braking action.
