Abstract
A clutch brake is provided that includes a brake housing adapted to be non-movably secured relative to a driveline master clutch. The brake housing includes a through-hole sized to allow passage of a shaft and at least one source of magnetic flux. The clutch brake also includes an armature secured for rotation with the shaft and positioned axially adjacent the brake housing in a disengaged state. At least a portion of the armature is adapted to move axially on the shaft in the presence of magnetic flux to contact the brake housing in an engaged state and inhibit rotation of the armature and the shaft.
Claims30
A clutch brake, comprising:
- a brake housing adapted to be non-movably secured in an axial direction relative to a driveline master clutch, the brake housing including at least two sources of magnetic flux and a through-hole sized to allow passage of a shaft;
- and
- an armature secured for rotation with the shaft and positioned axially adjacent the brake housing in a disengaged state, at least a portion of the armature adapted to move axially on the shaft in the presence of magnetic flux to contact the brake housing in an engaged state and inhibit rotation of the armature and the shaft, wherein the armature includes a number of slots positioned to separate lines of magnetic flux generated by a first source of magnetic flux from lines of magnetic flux generated by a second source of magnetic flux.
A driveline clutch assembly, comprising:
- a master clutch for transmitting rotational power between a prime mover and a transmission input shaft
- a release bearing and a release bearing actuating member adapted to move the release bearing to engage and disengage the master clutch;
- and
- a clutch brake, including:
- a brake housing adapted to be non-movably secured in an axial direction relative to the master clutch, the brake housing including at least one source of magnetic flux and a through-hole sized to allow passage of a shaft;
- and
- an armature secured for rotation with the shaft and positioned axially adjacent the brake housing in a disengaged state, at least a portion of the armature adapted to move axially on the input shaft in the presence of magnetic flux to contact the brake housing in an engaged state to inhibit rotation of the armature and the input shaft.
A combination brake and bearing cap, comprising:
- a brake housing adapted to secure a component of a bearing seal, the brake housing including a bearing seal retaining surface, at least one source of magnetic flux, and a through-hole sized to allow passage of a shaft;
- and
- an armature secured for rotation wit the shaft and positioned axially adjacent the brake housing in a disengaged state, at least a portion of the armature adapted to move axially on the shaft in the presence of magnetic flux to contact the brake housing in an engaged state to inhibit rotation of the armature and the shaft.
