Abstract

A hub assembly includes a retainer housing, a retaining member, a biasing element, and an occlusion. The retainer housing includes a wheel mounting sleeve and a pin sleeve. The wheel mounting sleeve includes an axle bore configured to receive an axle. The pin sleeve has a first end and a second end. The pin sleeve includes a conduit between the first end and the second end. The first end is in fluid communication with the axle bore. The retaining member and the biasing element are in the conduit. The retaining member is configured to engage a groove in an axle. The biasing element is configured to bias the retaining member towards the axle bore. The occlusion is proximate to the second end of the pin sleeve. The occlusion is configured to inhibit the retaining member from exiting the conduit at least prior to coupling the hub assembly to a wheel.

Claims

1. A wheel assembly comprising:

an axle bore;

a pin sleeve including a first end in fluid communication with the axle bore, a second end, and a conduit between the first end and the second end;

a retaining member at least partially in the conduit of the pin sleeve, the retaining member configured to operatively engage a groove in an axle and comprising a chamfered end extending into the axle bore, the chamfered end shaped to transversely displace the retaining member upon movement of an axle into the axle bore, the retaining member includes a flat surface configured to prevent rotation of the retaining member;

a biasing element at least partially in the conduit, the biasing element configured to bias the retaining member towards the axle bore; and

a restraining element configured to prevent the retaining member from exiting the second end of the pin sleeve, wherein the restraining element comprises a deformation.

2. The wheel assembly of claim 1, wherein the retaining member comprises a pin.

3. The wheel assembly of claim 1, wherein the first end of the pin sleeve includes a shoulder extending into the conduit, wherein the retaining member includes a lip wider than the shoulder, and wherein the lip and the shoulder interact to prevent the retaining member from exiting the first end of the pin sleeve.

4. The wheel assembly of claim 1, wherein the deformation comprises a plurality of ledges.

15. The wheel assembly of claim 4, wherein the plurality of ledges comprises four ledges circumferentially spaced by 90°

.

18. The wheel assembly of claim 1, wherein the deformation comprises a heat deformation.

5. A wheel assembly comprising:

an axle bore;

a pin sleeve including a first end in fluid communication with the axle bore, a second end, and a conduit between the first end and the second end;

a retaining member at least partially in the conduit of the pin sleeve, the retaining member configured to operatively engage a groove in an axle, the retaining member shaped to move towards the second end of the pin sleeve upon movement of the axle into the axle bore;

a biasing element at least partially in the conduit, the biasing element configured to bias the retaining member towards the axle bore; and

a restraining element configured to prevent the retaining member from exiting the second end of the pin sleeve, wherein the restraining element comprises a deformation.

6. The wheel assembly of claim 5, wherein the retaining member includes a flat surface configured to prevent rotation of the retaining member.

7. The wheel assembly of claim 5, wherein the retaining member comprises a pin.

8. The wheel assembly of claim 5, wherein the first end of the pin sleeve includes a shoulder extending into the conduit, wherein the retaining member includes a lip wider than the shoulder, and wherein the lip and the shoulder interact to prevent the retaining member from exiting the first end of the pin sleeve.

9. The wheel assembly of claim 5, wherein the deformation comprises a plurality of ledges.

16. The wheel assembly of claim 9, wherein the plurality of ledges comprises four ledges circumferentially spaced by 90°

.

19. The wheel assembly of claim 5, wherein the deformation comprises a heat deformation.

10. A wheel assembly comprising:

an axle bore;

a pin sleeve including a first end in fluid communication with the axle bore, a second end, and a conduit between the first end and the second end;

a retaining member at least partially in the conduit of the pin sleeve, the retaining member configured to operatively engage a groove in an axle, the retaining member shaped to prevent rotation of the retaining member;

a biasing element at least partially in the conduit, the biasing element configured to bias the retaining member towards the axle bore; and

a restraining element configured to prevent the retaining member from exiting the second end of the pin sleeve, wherein the restraining element comprises a deformation.

11. The wheel assembly of claim 10, wherein the retaining member includes a flat surface configured to prevent rotation of the retaining member.

12. The wheel assembly of claim 10, wherein the retaining member comprises a pin.

13. The wheel assembly of claim 10, wherein the first end of the pin sleeve includes a shoulder extending into the conduit, wherein the retaining member includes a lip wider than the shoulder, and wherein the lip and the shoulder interact to prevent the retaining member from exiting the first end of the pin sleeve.

14. The wheel assembly of claim 10, wherein the deformation comprises a plurality of ledges.

17. The wheel assembly of claim 14, wherein the plurality of ledges comprises four ledges circumferentially spaced by 90°

.

20. The wheel assembly of claim 10, wherein the deformation comprises a heat deformation.
