Abstract
A drive axle unit for use in a motor vehicle having a multi-piece axle housing assembly including at least two housing components interconnected via at least one in-situ molded retainer component. A method for securing at least two housing components of an axle housing assembly by injecting a molten material into a pair of aligned mold indentations formed in the two housing components which solidifies to create an in-situ molded retainer component.
Claims22
A drive axle unit for use in a motor vehicle comprising:
- a multi-piece axle housing assembly including at least a first housing component and a second housing component;
- at least one in-situ molded retainer component interconnecting the first and second housing components;
- a pinion shaft assembly;
- and
- a differential assembly;
- wherein the first housing component is an axle housing configured to define a pinion housing segment rotatably supporting the pinion shaft assembly and a differential housing segment rotatably supporting a first portion of the differential assembly, wherein the first housing component defines a first mold groove, and the second housing component defines a second mold groove in alignment with the first mold groove to define a retention mold chamber between the first and second mold grooves, and wherein the at least one in-situ molded retainer component is disposed in the retention mold chamber.
