Abstract

An axle assembly for a motorcycle having a plurality of drive wheels. The axle assembly is configured to permit a user to replace an endless power-transmitting element without substantially disassembling the axle housing assembly.

Claims (21)

1. An axle assembly that is configured for use in a motorcycle having a pair of driven wheels, the axle assembly comprising:

a case;

a drive member coupled to the case, the drive member comprises a pulley or a sprocket that is configured to engage an endless power transmitting element;

a pair of bearings mounted to opposite ends of the case; and

a carrier housing assembly having a carrier housing and a pair of bearing caps, each of the bearings being received between the carrier housing and an associated one of the bearing caps to support the case for rotation relative to the carrier housing assembly about a rotational axis, the carrier housing having a first opening, which is configured to receive the endless power transmitting element there through, and a second opening that is adapted to cooperate with the first opening to permit air to flow through the carrier housing when the motorcycle is driven.

2. The axle assembly of claim 1 , wherein the case is part of a differential assembly having a pair of output members, and wherein the axle assembly further comprises a pair of shafts that are adapted to transmit rotary power from the output members to the driven wheels.

3. The axle assembly of claim 2 , further comprising a pair of axle tubes that are coupled to opposite ends of the carrier housing, each of the axle tubes housing a corresponding one of the shafts.

4. The axle assembly of claim 3 , wherein each axle tube comprises a bearing mount and the axle assembly further comprises a pair of shaft bearings, wherein each of the shaft bearings is mounted on an associated one of the shafts and is axially slidably received into an associated one of the bearing mounts.

5. The axle assembly of claim 4 , further including a pair of retaining plates, each of the retaining plates abutting a side of a corresponding one of the shaft bearings so that each shaft bearing is disposed between the carrier housing and one of the retaining plates.

6. The axle assembly of claim 5 , wherein the retaining plates are configured to cooperate with the bearing mounts to apply a clamping force to outer races of the shaft bearings to inhibit rotation of the outer races relative to the bearing mounts.

7. An axle assembly that is configured for use in a motorcycle having a pair of driven wheels, the axle assembly comprising:

a differential assembly having a differential case and a differential gearset received in the differential case;

a drive member coupled to the differential case, the drive member comprising a pulley or a sprocket that is configured to engage an endless power transmitting element;

a pair of sealed bearings mounted to opposite ends of the case; and

a carrier housing assembly having a carrier housing and a pair of bearing caps, each of the bearings being received between the carrier housing and an associated one of the bearing caps to support the case for rotation relative to the carrier housing assembly about a rotational axis, the carrier housing comprising a front surface that is configured to face toward a front wheel of the motorcycle, the front surface defining an unsealed opening that is configured to receive the endless power transmitting element therethrough;

wherein the carrier housing is configured to permit air to flow therethrough during operation of the axle assembly.

8. The axle assembly of claim 7 , further comprising a pair of axle shafts drivingly connected to output members of the differential gearset.

9. The axle assembly of claim 8 , further comprising a pair of axle tubes that are coupled to opposite ends of the carrier housing, each of the axle tubes housing a corresponding one of the axle shafts.

10. The axle assembly of claim 7 , wherein the differential assembly is sealed to inhibit ingress of dirt and debris into the differential case.

11. The axle assembly of claim 7 , wherein a Zerk fitting is coupled to the differential case.

12. The axle assembly of claim 7 , wherein the carrier housing encircles the drive member.
