Abstract
The present invention concerns a brake system creating redundancy in electromechanical brakes. At least two drive units are provided at each single brake for activation of the brake. The at least two units may be controlled and/or energized separately. To safeguard the function the control and/or energy source systems are formed in two nets. The at least two units of each brake are connected to separate nets. The at least two units may be separate electrical motors.
Claims17
A brake system characterized in that each single brake has a redundancy regarding activation and that at least two drive units are provided at each single brake for activation of said each single brake;
- and
- characterized in that the at least two units are one motor package with thermally and electrically insulated winding packets in an stator portion and a common rotor on a common shaft.
A brake system for a motor vehicle, said brake system comprising:
- a plurality of brakes, each brake of said plurality of brakes having a corresponding brake actuator;
- wherein the brake actuator of at least one of said plurality of brakes comprises:
- a plurality of separately operable brake application units;
- a source of electrical energy corresponding to each brake application unit of said plurality of brake application units;
- and
- said source of electrical energy for energizing said corresponding brake application unit, which results in said corresponding brake application unit being capable of actuating said corresponding brake without other brake application units.
