Fig. 2 is partial enlarged drawing of the present utility model.
Detailed description of the invention
See accompanying drawing:
Torsion beam suspension, comprises crossbeam 1, and crossbeam 1 two ends are arranged with longeron 2, the lower end of longeron 2 be connected with longitudinal, for the boss plate 3 of installing wheel; Longeron 2 be installed with spring perch 4 with the lower end, junction of crossbeam 1, the longeron 2 on the downside of spring perch 4 is provided with mounting bracket of shock absorber 5, and the downside of spring perch 4 outer wall is also welded and fixed with the upside of shock absorber support 5 outer wall; The upper end madial wall of longeron 2 is provided with stirrup 6.
Crossbeam 1 has thick metal plate punching to form usually, and thickness is generally 5mm ~ 7mm, and the opening shape up or down of crossbeam 1 can adopt U-shaped or V-type, and namely middle part outwardly convex becomes U-shaped or V-arrangement; If necessary, also can adopt the shape of variable section, the performance putting on torsion beam that can be higher.
