Described torsion bar soldering member comprises torsion bar, be positioned at the torsion bar anchor at torsion bar two ends and be positioned at 2 discs at torsion bar middle part, and torsion bar, torsion bar anchor and 2 discs that are positioned at the torsion bar middle part link into an integrated entity by welding manner, wherein on torsion bar anchor
Fixing2 welded nuts are arranged;
Described torsion bar stabilizing member has opening on one side, snaps between the disc of two, torsion bar middle part by this opening, and the torsion bar stabilizing member can not sway;
2 bolts assemblies of the torsion bar soldering member that is equipped with the torsion bar stabilizing member by torsion bar anchor on the crossbeam of torsion beam soldering member, 1 bolts assemblies is on the crossbeam brace panel.
Its further technical scheme is: described torsion bar stabilizing member is Rubber Parts, structure triangular in shape, the centre has the circular hole by torsion bar, with torsion bar be interference fit; There is opening on one side that described torsion bar stabilizing member contacts with crossbeam, with described crossbeam interference fit, by press fit on torsion bar.
Because the semi-independent rear suspension of the present invention's automobile torsion beam is demountable structure, be assembled by torsion beam soldering member, torsion bar soldering member and the torsion bar stabilizing member of separate structure, so the semi-independent rear suspension of automobile torsion beam of the present invention has following beneficial effect:
1. the torsion bar soldering member that is welded as a whole separately of torsion bar, torsion bar anchor, pad, be convenient to the shot-peening application, and it first carried out electrophoretic painting, refills and join the torsion bar stabilizing member, can effectively guarantee torsion bar and support life-span thereof.
2. the torsion bar stabilizing member is assemblied on the torsion bar soldering member by the mode of extruding, is convenient to assembly and disassembly, has reduced torsion bar twisting stress and exciting; And guarantee that described torsion bar stabilizing member can not come off in the work such as torsion beam distortion.
3. the torsion bar soldering member is bolted on the crossbeam of torsion beam soldering member, is convenient to change torsion bar, and processing is simple, cost is low.
