Embodiment Construction

[0033] like image 3 As shown, a rear axle final drive and bushing assembly assembly process of the present invention includes the following steps:

[0034] Step 1. Weld the steel plate seat 4 and the shock absorber bracket 5 on the left half-shaft casing 1 and the right half-shaft casing 2 respectively to form the left half-shaft casing assembly and the right half-shaft casing assembly;

[0035] Step 2. Synchronously, the components of the final drive assembly 6 are sequentially assembled into the rear axle housing 3 on the assembly line to form the final drive drive assembly;

[0036] Step 3. Press the left half-shaft bushing assembly and the right half-shaft bushing assembly formed in step 1 into the rear axle main reducer assembly formed in step 2 at the same time by hot pressing process, and finally form the rear axle main reducer with bushing assembly.

[0037] The rear axle main reducer and sleeve assembly assembly equipment and process provided by the present inventi...

Abstract

The invention discloses commercial vehicle rear axle main speed reducer and sleeve assembly assembling equipment and process. A left half axle sleeve assembly and a right half axle sleeve assembly arepressed into a rear axle shell hole in a rear axle main speed reducer assembly at the same time by adopting a double-end hot pressing process. Double-end hot-pressing process equipment and a corresponding assembling process are adopted for assembling of the rear axle main speed reducer and the sleeve assembly, the problems of press-in depth fluctuation and scrap iron extrusion caused by the left-right pressure difference can be effectively solved, and the product quality stability and performance are guaranteed.
