A suspension system for a wheeled vehicle is provided, the suspension system being adapted to support at least one wheel of the vehicle and comprising at least one shock absorbing device adapted to be activated as a result of the motion of the at least one wheel in a substantially vertical direction, the suspension system further comprising electrical power generating means in fluid connection with the at least one shock absorbing device so that the activation of said at least one shock absorbing device results in electrical power being generated. Furthermore, the suspension system comprises means for absorbing at least partially the electrical power generated, the absorption of electrical power resulting in the stiffness of said at least one shock absorbing device being varied as a function of the electrical power absorbed.
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.
