SEMI-TRAILER AXLE AND SUSPENSION CONNECTING STRUCTURE

摘要

A semi-trailer axle and suspension connecting structure includes an axle (5), a suspension system and a connecting member arranged on the axle (5) body and a suspension support plate (6) of the suspension system. A locating structure is arranged on the match surface of the axle (5) and the suspension support plate (6) to prevent the circumferentially and axially relative displacement between the axle (5) and the suspension support plate (6). The invention omits a welding process for the axle body and the suspension support plate (6). The axle body  still keeps a good strength structure while the firm connection of the axle body and the suspension arrives, and the stress damage caused by welding is avoided.
