Abstract
A wheel end assembly includes a first shaft supported on a knuckle secured to a vehicle frame, including first clutch teeth, a second shaft secured to the halfshaft, a coil, and a collar rotatably secured to the second shaft, axially displaceable relative to the first shaft, including second clutch teeth that alternately engage the first clutch teeth due to an electromagnetic field produced by energizing the coil and disengage from the first clutch teeth.
Claims18
A wheel end assembly, comprising:
- an outboard shaft supported on a knuckle secured to a vehicle frame, including first clutch teeth;
- an inboard shaft;
- a coil;
- a plunger;
- a spring biasing the plunger axially away from the outboard shaft;
- a collar rotatably secured to the inboard shaft, axially displaceable relative to the outboard shaft, including second clutch teeth;
- a thrust bearing located axially between the plunger and the collar that transmits axial movement of the plunger to the collar when the coil is energized to engage the first and second clutch teeth.
4 more elements
A wheel end assembly, comprising:
- an outboard shaft, secured to a wheel hub, including an inboard end face having radially extending first dog teeth;
- an inboard shaft;
- a coil;
- a collar, rotatably secured to the inboard shaft and axially displaceable relative to the outboard shaft, including an outboard end face having radially extending second dog teeth that engage the first dog teeth due to energizing the coil.
1 more element
A wheel end assembly, comprising:
- an outboard shaft for transmitting torque to a wheel hub, including radially extending first dog teeth;
- an inboard shaft;
- a coil radially outboard of and axially spaced from the outboard shaft;
- a collar, rotatably secured to the inboard shaft and axially displaceable relative to the outboard shaft, including an outboard end face having radially extending second dog teeth that engage the first dog teeth due to energizing the coil.
