Abstract
A brake assembly coupled to a wheel is disclosed herein. The brake assembly includes a plurality of stator disks, a plurality of rotor disks interleaved with the plurality of stator disks and configured to apply a braking force to the wheel, a pressure plate disposed adjacent a rotor disk of the plurality of rotor disks, a first electric brake actuator disposed adjacent the pressure plate and configured to apply the braking force to the pressure plate, the first electric brake actuator including a parking brake mechanism, and a second electric brake actuator disposed adjacent the pressure plate and configured to apply the braking force to the pressure plate.
Claims20
A brake assembly coupled to a wheel, comprising:
- a plurality of stator disks;
- a plurality of rotor disks interleaved with the plurality of stator disks and configured to apply a braking force to the wheel;
- a pressure plate disposed adjacent a rotor disk of the plurality of rotor disks;
- a first electric brake actuator disposed adjacent the pressure plate and configured to apply the braking force to the pressure plate, the first electric brake actuator including a parking brake mechanism;
- and
- a second electric brake actuator disposed adjacent the pressure plate and configured to apply the braking force to the pressure plate.
A system, comprising:
- a brake assembly coupled to a wheel;
- a first electric brake actuator configured to engage the brake assembly, the first electric brake actuator including a parking brake mechanism;
- a second electric brake actuator configured to engage the brake assembly;
- a controller;
- and
- a memory operatively coupled to the controller, the memory comprising instructions stored thereon that, when executed by the controller, cause the controller to:
- receive a first request to apply a first braking force to the brake assembly;
- send a first signal to the first electric brake actuator and to the second electric brake actuator to apply the first braking force to cause the wheel to stop rotating;
- receive a second request to engage the parking brake mechanism;
- and
- send a second signal to the first electric brake actuator to apply a second braking force to the brake assembly.
A method, comprising:
- receiving, by a controller, a first request to apply a parking brake to a wheel;
- sending, by the controller, a brake signal to a first electric brake actuator to apply a braking force in response to the first request, the first electric brake actuator coupled to a first brake assembly, the first brake assembly coupled to the wheel, and the first brake assembly including the first electric brake actuator and a second electric brake actuator;
- sending, by the controller, a parking mechanism engage signal to the first electric brake actuator to engage the parking brake mechanism of the first electric brake actuator;
- and
- sending, by the controller, a signal to stop applying the braking force by the first electric brake actuator.
