As shown in fig. 1, reference numeral a is a shock absorber support, and reference numeral b is a tubular trailing arm.
The outer longitudinal arm plate 1 and the inner longitudinal arm plate 2 are integrally formed by punching inner plates and outer plates and are formed by U-O forming.
Compare in current pipe fitting trailing arm body and bumper shock absorber support combination welded structural style, current trailing arm body and bumper shock absorber support combined type structure have that the structure is simpler, the performance is more superior, machining efficiency is high, the quality is more stable, the advantage that the cost is lower.
The outer plate 1 and the inner plate 2 of the longitudinal arm are compounded by welding, and one end of the outer plate and one end of the inner plate are integrated with a mounting point of a shock absorber.
