SUPPORT SHAFT FOR INTEGRAL VEHICLE-AXLE AND MANUFACTURING METHOD THEREOF

摘要

A support shaft for an integral vehicle-axle includes a main body (10). The main body (10) of the support shaft includes several plate-form parts (11) welded with each other, forming a transversal section of the main body (10) of the support shaft has a hollow shape. A manufacturing method for a support shaft for an integral vehicle-axle is disclosed. The steps of the manufacturing method include welding several pale-form parts prepared into a main body (10) of the support shaft with hollow transversal section. Compared with the conventional integral vehicle-axle, the main body (10) of the support shaft for the integral vehicle-axle according to the subject matter in the invention is formed by several plate-form parts welded and has transversal section with hollow shape. Thus the support shaft of the invention can meet the requirements for flexible manufacturing and fulfill the requirements for application with lower cost.
