Abstract
A braking system for a motor vehicle includes a brake housing, a drum brake arranged in the brake housing, a brake shoe, a brake actuator and an electric machine. The drum brake has a brake drum and the brake shoe is arranged to apply a friction torque to the brake drum. The brake actuator is arranged to radially displace the brake shoe towards the brake drum to apply the friction torque. The electric machine has a rotor coupled to the brake drum and arranged to be coupled to a wheel of the motor vehicle. The braking system may include a brake cooling circuit arranged for dissipating heat from the drum brake.
Claims20
A braking system of a motor vehicle which can be electrically driven by means of an electric machine, wherein the braking system comprises a drum brake with a brake drum, to which friction torque can be applied by means of at least one brake shoe which can be displaced radially in the direction of the brake drum by a brake actuator, and the electric machine has a rotor which is coupled in a torque-transmitting manner to at least one vehicle wheel of the motor vehicle,
- wherein:
- the drum brake is accommodated in a brake housing and the brake drum is connected to the rotor of the electric machine in a torque-transmitting manner.
A braking system for a motor vehicle, comprising:
- a brake housing;
- a drum brake arranged in the brake housing and comprising a brake drum;
- a brake shoe arranged to apply a friction torque to the brake drum;
- a brake actuator arranged to radially displace the brake shoe towards the brake drum to apply the friction torque;
- and
- an electric machine comprising a rotor coupled to the brake drum and arranged to be coupled to a wheel of the motor vehicle.
