Differential assembly and method of assembly
View Patent ↗A method of assembling a differential assembly and a biasing element for a differential wherein the biasing element may be added or removed from an assembled differential without having to remove the pinion shaft. The biasing element is generally a W-spring that includes a center opening and open sides that face the same direction to facilitate the addition or removal of the biasing element.
1. A biasing element comprising:
a center section having a length, said center section including a base opposite an insertion opening, said insertion opening extending said length;
a center opening defined by said center section and including said insertion opening;
a pair of legs disposed on each side of said center section, each of said legs defining a cavity having an open side and wherein each of said center opening, said insertion opening and said open sides face the same direction and wherein said open sides and said insertion opening are each located on an insertion side.
2. The biasing element of claim 1 wherein said center section further defines a pair of side walls extending from said base, and wherein each of said side walls further include engagement detents.
3. The biasing element of claim 2 wherein said detents are opposing arcuate segments defined by said side walls.
4. The biasing element of claim 2 wherein said center section includes a side opening in each of the side walls, said openings further defining said cavities.
5. The biasing element of claim 1 wherein said center section includes a pair of side walls extending between said base and said legs and wherein said legs and said side walls meet at said insertion side.
6. The biasing element of claim 5 wherein said center opening further includes pinion shaft openings defined by said center section and said side walls, said pinion shaft openings being located adjacent to said insertion opening.
7. The biasing element of claim 5 wherein said legs extend away from said insertion side.
8. The biasing element of claim 1 wherein said legs include leg ends and wherein said leg ends are opposite said insertion side.
9. The biasing element of claim 1 wherein said legs include leg ends and wherein said leg ends are on the same side as said base.
10. The biasing element of claim 1 wherein said insertion opening is capable of receiving a pinion shaft.
