Abstract
A half-shaft assembly includes a first constant velocity (CV) joint, a second CV joint and an axial movement joint connected between the first CV joint and the second CV joint. The axial movement joint includes a first shaft coupled to the first CV joint and a second shaft coupled to the second CV joint, wherein mechanical input received on the first shaft is communicated to the second shaft, and wherein the second shaft slides axially within the first shaft. The axial movement joint further includes an axial boot cover coupled on a first end to the first shaft and on a second end to the second shaft that accommodates axial movement of the first shaft relative to the second shaft.
Claims18
A recreational vehicle comprising:
- a frame;
- a plurality of trailing arms;
- a plurality of ground engaging members, each ground engaging member including a wheel, wherein at least one wheel is secured to the frame via one of the trailing arms;
- an engine;
- a driveline connected to the engine;
- a half-shaft assembly configured to communicate power from the driveline to one of the plurality of wheels, the half-shaft assembly comprising:
- an axial movement joint having:
- a first shaft and a second shaft, wherein rotational input received on the first shaft is communicated to the second shaft, and wherein the axial movement joint allows axial movement of the first shaft relative to the second shaft, the axial movement joint having an axial boot cover coupled on a first end to the first shaft and on a second end to the second shaft that accommodates axial movement of the first shaft relative to the second shaft, wherein either the first shaft or the second shaft is at least partially hollow;
- and
- a plurality of ball bearings retained within a cage positioned between the first shaft and the second shaft to allow axial plunge or movement of the second shaft relative to the first shaft;
- a first constant velocity (CV) joint coupled to transmit rotational input received from the driveline to the first shaft, the first CV joint having a first CV boot cover;
- and
- a second CV joint coupled to transmit rotational output received from the second shaft to one of the plurality of wheels, the second CV joint having a second CV boot cover.
