Abstract
In some examples, a braking system includes a housing configured to rotate around a torque tube. A disc stack includes a plurality of stator discs are coupled to the torque tube and a plurality of rotor discs rotationally coupled to the housing. An actuator within the torque tube is configured to compress the disc stack. A portion of the torque tube may be configured to insert into an axial assembly of a wheel. The housing may be connected to a portion of a wheel rim. The braking system may be present on a wheel instead of or in addition to a main braking system having a main disc stack.
Claims20
An auxiliary braking system comprising:
- a torque tube defining a wheel axis of a wheel, wherein the torque tube includes an insertion portion configured to insert within a volume defined by an assembly supporting the wheel;
- a housing configured to rotate around the wheel axis relative to the torque tube;
- a disc stack comprising:
- a plurality of rotor discs rotationally coupled with the housing;
- and
- a plurality of stator discs coupled with the torque tube and interleaved with the plurality of rotor discs, wherein the torque tube is configured to limit rotational movement of the plurality of stator discs relative to the torque tube when the plurality of stator discs are coupled to the torque tube;
- and
- an actuator configured to compress the disc stack, wherein the actuator includes an actuator body mechanically connected to the insertion portion of the torque tube.
