Abstract:
PCT No. PCT/GB96/02255 Sec. 371 Date May 14, 1998 Sec. 102(e) Date May 14, 1998 PCT Filed Sep. 13, 1996 PCT Pub. No. WO97/10449 PCT Pub. Date Mar. 20, 1997An electrically operated disc brake assembly for vehicles of the kind in which a friction member (9) is adapted to be applied to a rotatable brake disc (2) by a brake applying mechanism which includes an electric motor (3) and a transmission which is adapted to apply an axially directed brake applying force to the friction member (9) in response to operation of the motor (3) so that the transmission acts on the friction member (9) at circumferentially spaced locations. This produces a substantially even loading across the friction member/disc interface, reducing the magnitude of the reaction torque. In one embodiment, the transmission comprises a pair of axially spaced screw devices (4,5) which are rotatable by the motor (3) acting through a common gear train (6), and the motor may further be provided at the center of mass of the brake.
