Abstract
A sealing system includes a shaft seal plate, a seal guide having a tab, and a shaft seal coupled to the seal guide. A guide slot is formed in the shaft seal plate, and the tab extends into the guide slot. The shaft seal is configured to form and substantially maintain a seal at an axle bar as the axle bar rotates and pivots. The seal guide is configured to translate relative to the shaft seal plate as the axle bar pivots, and the tab is configured to block a rotation of the seal guide and the shaft seal relative to the shaft seal plate as the axle bar rotates.
Claims18
A sealing system, comprising:
- a shaft seal plate, wherein a guide slot is formed in the shaft seal plate;
- a seal guide comprising a tab and a seal guide extension, wherein the tab extends in a first direction into the guide slot and the seal guide extension extends in a second direction that is substantially perpendicular to the first direction;
- a shaft seal coupled to the seal guide extension, wherein the shaft seal is configured to form and substantially maintain a seal at an axle bar as the axle bar rotates and pivots, the seal guide is configured to translate relative to the shaft seal plate as the axle bar pivots, and the tab is configured to block rotation of the seal guide and the shaft seal relative to the shaft seal plate as the axle bar rotates;
- and
- a boot comprising a first end statically attached to the shaft seal plate and a second end statically attached to the seal guide extension,
- wherein the seal guide extension is positioned between the second end of the boot and the shaft seal along the first direction.

A suspension system, comprising:
- an axle housing;
- and
- a sealing system, comprising:
- a shaft seal plate coupled to the axle housing, wherein a guide slot is formed between the shaft seal plate and the axle housing;
- a seal guide comprising a tab and a seal guide extension, wherein the tab extends in a first direction into the guide slot and the seal guide extension extends in a second direction that is substantially perpendicular to the first direction;
- a shaft seal coupled to the seal guide extension, wherein the shaft seal is configured to form and substantially maintain a seal at an axle bar of the suspension system as the axle bar rotates and pivots, the seal guide is configured to translate relative to the shaft seal plate as the axle bar pivots, and the tab is configured to block rotation of the seal guide and the shaft seal relative to the shaft seal plate as the axle bar rotates;
- and
- a boot comprising a first end statically attached to the shaft seal plate and a second end statically attached to the seal guide extension,
- wherein the seal guide extension is positioned between the second end of the boot and the shaft seal along the first direction.
6 more elements
A sealing system for a suspension system, comprising:
- a shaft seal plate, wherein a guide slot is formed within the shaft seal plate;
- a seal guide comprising a tab, a seal guide extension, and a seal guide bushing, wherein the tab is configured to extend in a first direction into the guide slot and the seal guide extension extends in a second direction that is substantially perpendicular to the first direction;
- a shaft seal coupled to the seal guide extension, wherein the shaft seal is configured to form and substantially maintain a seal at an axle bar of the suspension system as the axle bar rotates and pivots, the seal guide is configured to translate relative to the shaft seal plate as the axle bar pivots, the tab is configured to block rotational movement of the seal guide and the shaft seal relative to the shaft seal plate as the axle bar rotates, and the seal guide bushing is configured to block lateral movement of the seal guide along the axle bar via contact with an annular protrusion of the axle bar;
- and
- a boot comprising a first end statically attached to the shaft seal plate and a second end statically attached to the seal guide extension,
- wherein the seal guide extension is positioned between the second end of the boot and the shaft seal along the first direction.
