Control system for an electromotive wheel brake

The invention concerns a control or adjustment system for a wheel brake operated by an electric motor. Brakes of this type are fitted with an electric motor which presses the friction blocks against the brake disk. Two problems need to be addressed. One is to transmit as sensitively as possible an application force which will cause the vehicle to decelerate as required. The second is to set a clearance following braking. That clearance must be maintained as accurately as possible. The control strategies are different in each case. It is therefore proposed that the electric motor should be actuated via an electronic servo booster (49) which, depending on the particular problem to be addressed, is itself actuated either via a deceleration controller (46) or via a position controller (52).

Electromechanical braking device

The invention relates to an electromagnetic brake system (50). To actuate a disk brake (52), the brake system is provided with two electric motors (86, 92) whose rotary movements are superimposed by a threaded roller gear (60) which forms a differential drive system and converted to linear motion. Using both electric motors (86, 92) as drives facilitates rapid correction of clearance and subsequently, once one electric motor (86, 92) has been switched off, generation of a high braking force with the electric motor (92, 86) which has the higher step-down ratio. Another advantage is the system redundancy, i.e. in the event of failure of one of the electric motors (86, 92) the brake system (50) can be fully released by the other motor.

Hydraulic vehicle brake with blocking means

A hydraulic vehicle brake (10) has a hydraulic chamber (16) in which a brake piston (18) can slide in a sealing manner along an axis (A). The brake piston (18) acts upon a friction member and can be pushed by hydraulic pressure fed into the hydraulic chamber (16) into an actuation position in which it presses the friction member against a rotor (brake disk, brake drum, etc.). To enable the brake (10) to be used also as a parking brake, besides its function as a hydraulic service brake, a spindle/nut arrangement (24) driven by an electric motor (42) and extending coaxially to the axis (A) of the brake piston (18) is provided. The nut (30) of the spindle/nut arrangement (24) is secured against rotation and by rotating the spindle (26) can be moved along the axis (A) either up to or away from the brake piston (18), depending on the direction of rotation. In order to obtain a compact and economic design, the output shaft (46) of the electric motor (42) extends from the side of the electric motor (42) away from the brake piston (18) in a parallel direction to the axis (A), from which it is laterally spaced apart. Moreover, a reducing gear (44) with a reducing ratio in the order of 200:1 is connected between the electric motor (42) and the spindle (26), the electric motor (42) and the reducing gear (44) being designed as subassemblies (40) that can be handled separately.
