Embodiment Construction

[0036] Combine Figure 3 to Figure 6 In the first embodiment of the present invention, the torsion beam suspension includes a cross beam 100, a longitudinal arm 200 and a spring tray 300, and the cross beam 100 is connected to the longitudinal beam 200. Wherein, the cross beam 100 includes a cross beam upper plate 110 and a cross beam lower plate 120. The cross beam upper plate 110 and the cross beam lower plate 120 are buckled together and welded to form a Image 6 Box structure shown. There is a gap 111 at the end of the upper beam 110, where the trailing arm 200 is completely clamped between the upper beam 110 and the lower plate 120, and then welded and connected. figure 1 Compared with the structure in which the longitudinal arm 1 is directly overlapped and welded with the beam 2, the force and moment transmitted by the longitudinal arm 200 to the beam 100 are uniform, and cracks are not easily generated. From Figure 4 It can be seen more clearly that the trailing arm 200...

Abstract

The present invention provides a trailing arm of a torsion beam suspension, comprising a trailing arm upper plate and a trailing arm lower plate, the trailing arm upper plate and the trailing arm lower plate are buckled together to form a box-shaped structure, the longitudinal arm The lower arm plate is integrally formed with a spring tray. The present invention also provides a torsion beam suspension using the above-mentioned trailing arm. The structure of the invention has high strength and is not easily torn.

Description

Technical field [0001] The invention relates to the field of automobile suspension, in particular to a trailing arm of a torsion beam suspension and a torsion beam suspension. Background technique [0002] Torsion beam suspension (also known as torsion beam suspension) is one of the suspension types used for the load-bearing of automobile chassis, such as figure 1 with figure 2 As shown, the main structure includes the trailing arm 1, the cross beam 2, the spring tray 3, the reinforcing connecting plate 5, etc., and the whole is connected by welding. The torsion beam suspension structure is that during the operation of the vehicle, due to the unevenness of the road surface and the driving manipulation, the vehicle load and the left and right feedback of the road surface, the spring 4 compresses or rebounds, and then is transmitted to the beam 2 through the trailing arm 1 The beam 2 produces a process of torsion transmission or offsetting its movement. The key to the movement of...
