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 crossbeam 100 includes a crossbeam upper plate 110 and a crossbeam lower plate 120, and the crossbeam upper plate 110 and the crossbeam lower plate 120 are snapped together and welded to form a Image 6 The box-shaped structure shown. There is a notch 111 at the end of the upper beam plate 110, where the longitudinal arm 200 is fully clamped between the upper beam plate 110 and the lower beam plate 120, and then welded, so that, with figure 1 Compared with the structure in which the longitudinal arm 1 and the cross beam 2 are directly overlapped and welded, the force and moment transmitted from the longitudinal arm 200 to the cross beam 100 are uniform, and cracks are less likely to occur. from Figure 4 It...

Abstract

The invention provides a longitudinal arm of a torsion beam suspension frame. The longitudinal arm comprises a longitudinal arm upper plate and a longitudinal arm lower plate, wherein the longitudinal arm upper plate and the longitudinal arm lower plate are buckled together for forming a box-shaped structure, and a spring tray is integrally formed on the longitudinal arm lower plate. The invention also provides the torsion beam suspension frame adopting the longitudinal arm. The longitudinal arm and the torsion beam suspension frame have the advantages that the structural intensity is high, and the tearing fracture cannot easily occur.

Description

technical field [0001] The invention relates to the field of automobile suspension, in particular to a longitudinal arm of a torsion beam suspension and the torsion beam suspension. Background technique [0002] Torsion beam suspension (also known as torsion beam suspension) is one of the suspension types used for the chassis of the car, such as figure 1 with figure 2 As shown, its main structure includes a longitudinal arm 1, a beam 2, a spring tray 3, a 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 driving manipulation, the vehicle load and the unevenness of the road surface feedback cause the spring 4 to compress or rebound, and then transmit it to the cross beam 2 through the longitudinal arm 1, and pass through Beam 2 produces torsional transmission or counteracts its motion process. The key to the movement o...
