The specific embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in detail.
As shown in Figure 1 to Figure 3, the supporting seat 1 of torsion bar spring comprises welding support assembly 11, and welding support assembly 11 comprises mainboard 111, side plate 112, base plate 113, seat ring 114, and base plate 113, side plate 112, seat ring 114 surround mainboard and be welded to connect with mainboard.Two side plates 112 are oppositely arranged, and base plate 113 is oppositely arranged with seat ring 114, and seat ring 114, two side plates 112 all contact with mainboard 111 is vertical.
In the seat ring 1 of supporting seat, be provided with rubber cushion assembly 12, rubber cushion assembly 12 has fixedly central siphon, prevents that operator's compartment side direction from jumping, eliminating the effect of side force.Preferably, supporting seat 1 comprises that rubber cushion assembly 12, rubber cushion assembly 12 are positioned at seat ring 114, and rubber cushion assembly 12 coordinates with the inwall of seat ring 114, and a side of rubber cushion assembly 12 has flange 121, and flange 121 is waled the outer wall of seat ring 114.Rubber cushion assembly 12 is pressed into the inwall of seat ring 114 by particular jig, the inwall of the outer ring of rubber cushion assembly 12 and seat ring 114 is interference fit, and flange 121 is positioned at a side of close central siphon assembly 4 on seat ring 114, and flange 121 has the effect that prevents operator's compartment axial jump.
