Differential and thrust washer therefor
A thrust washer and a differential containing a thrust washer. The differential has a housing, a spider and one or more spider gears. The thrust washer includes a body having an annular shape and a width configured to approximately match with a width of the one or more spider gears. The thrust washer is further configured to engage with the spider to prevent or reduce the thrust washer from rotating relative to the housing when the thrust washer is installed in the differential.
1. A thrust washer for a differential having a housing, a spider, and one or more spider gears, the thrust washer comprising:
a thrust washer body comprising an annular shape having a width configured to approximately match a width of the one or more spider gears and conform to a shape of the spider gears and further configured to engage with the spider to approximately prevent the thrust washer from rotating relative to the housing when the thrust washer is installed in the differential,
wherein the body is configured to have a slope along the width configured to conform with an inner diameter of the housing such that the slope engages with the housing to reduce separation of a first portion and a second portion of the thrust washer body.
2. The thrust washer of claim 1 , wherein the spider comprises at least one spider arm and wherein the thrust washer comprises at least one engagement mechanism having a size and a shape to engage with an outer diameter of the at least one spider arm to engage the thrust washer with the spider.
3. The thrust washer of claim 2 , wherein the at least one spider arm comprises four arms, the at least one engagement mechanism comprises four apertures, and each of the four apertures are positioned and oriented to engage a respective one of the four arms when the thrust washer is installed in the differential.
4. The thrust washer of claim 1 , wherein the first portion and the second portion are configured to assemble around the spider and the spider gears.
5. The thrust washer of claim 4 , wherein the first portion and the second portion are configured to provide a gap between the first portion and the second portion when assembled to allow the flow of debris or the like.
6. The thrust washer of claim 1 , wherein the thrust washer has a continuous ring shape.
7. The thrust washer of claim 1 , wherein the thrust washer comprises a gap across the width of the thrust washer.
8. A differential comprising:
a housing;
a spider and one or more spider gears;
at least two side gears positioned and oriented to engage the one or more spider gears within the housing; and
a thrust washer positioned between the housing and the at least one spider gear, the thrust washer comprising:
a body comprising an annular shape having a width configured to approximately match with a width of the one or more spider gears and further configured to engage with the spider to prevent the thrust washer from rotating relative to the housing when the thrust washer is installed in the differential,
wherein the body is configured to have a slope along the width configured to conform with an inner diameter of the housing and the slope engages with the housing to reduce separation of a first portion and a second portion of the body.
9. The differential of claim 8 , wherein the spider comprises at least one spider arm and wherein the thrust washer comprises at least one engagement mechanism having a size and a shape to engage with an outer diameter of the at least one spider arm to engage the thrust, washer with the spider.
10. The differential of claim 9 , wherein the at least one spider arm comprises four arms, the at least one engagement mechanism comprises four apertures, and wherein each of the four apertures are positioned and oriented to engage a respective one of the four arms when the thrust washer is installed in the differential.
11. The differential of claim 8 , wherein the slope along the width also conforms to a shape of the spider gears.
12. The differential of claim 8 , wherein the first portion and the second portion are configured to assemble around the spider and the spider gears.
13. The differential of claim 12 , wherein the first portion and the second portion are configured to provide a gap between the first portion and the second portion to allow the flow of debris or the like.
14. The differential of claim 8 , wherein the thrust washer has a continuous ring shape.
15. The differential of claim 8 , wherein the thrust washer comprises a gap across the width of the thrust washer.
16. The differential of claim 8 , wherein the thrust washer comprises a single contiguous body.
17. A thrust washer for a differential having a housing, a spider, and one or more spider gears, the thrust washer comprising:
a thrust washer body comprising an annular shape having a width configured to approximately match a width of the one or more spider gears, the thrust washer body comprising:
a first portion and a second portion, wherein each of the first and second portions are configured to engage with the spider to prevent the thrust washer from rotating relative to the housing when the thrust washer is installed in the differential and are also configured such that a slope along the width conforms with an inner diameter of the housing and engages with the housing to reduce separation of the first portion and the second portion.
