Further, elasticity shock-proof type vehicle control arm in, control arm body one end forms a bush hole in two vertical walls punching press respectively, two bush holes set up relatively and all inwards buckle have and turn over along two, the pressure equipment has the bush between two bush holes, increases bush and bush hole contact surface between them through turning over along two, improves its erection stability.

Further, elasticity shock-proof type vehicle control arm in, the bush includes inner tube, well skeleton and the outer tube that the coaxial cup jointed, vulcanize the connection through rubber construction between inner tube and the outer tube. And the design of three layers of frameworks is adopted, so that the strength of the bushing structure is improved.

Furthermore, in the elastic damping type automobile control arm, a drain hole is formed on the bottom plate.

Furthermore, elasticity shock-proof type vehicle control arm in, found the wall and outwards buckle respectively and form to turn over along three, the reinforcing plate is fixed on turning over along three. The contact surface between the reinforcing plate and the vertical wall is increased by turning over the third edge, so that the welding is firmer.

The utility model has the advantages that: the utility model discloses simple structure, reasonable in design, the toper tube-shape that can outwards warp to strut on the mounting hole designs turns over along the structure, is showing the area of contact who has increased mounting hole and bumper shock absorber on the one hand, and on the other hand is through because turning over along a pitch footpath convergent to combine the tension of elasticity hoop, make both contacts more inseparabler, effectively guarantee good connectivity between bumper shock absorber and the control arm, the installation is more firm.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings:

referring to fig. 1 and 2, the elastic damping type automobile control arm in the embodiment includes a control arm body with a U-shaped cross section, and includes a bottom plate 1 and two vertical walls 2 extending upwards from two sides of the bottom plate 1. The bottom plate 1 is recessed upwards to form a shock absorber accommodating cavity 3, the upper end of the shock absorber accommodating cavity 3 is provided with a mounting hole 4 for mounting a shock absorber, a reinforcing plate 6 is covered above the mounting hole 4, and two side edges of the reinforcing plate 6 are correspondingly welded with the two vertical walls 2; the reinforcing plate 6 is provided with a dismounting opening 5 for dismounting the shock absorber, and the section size of the dismounting opening 5 is larger than that of the mounting hole 4. The bottom plate 1 is also provided with a drain hole 7.

With reference to fig. 3 and 4, the mounting hole 4 extends upwards along the hole edge to form a conical cylindrical flange 8, the upper end of the flange 8 is provided with a plurality of axially extending openings 9 along the peripheral wall, and thus the upper end of the flange 8 is divided by the openings 9 to form a plurality of outwardly expandable fastening pieces; the upper end of the turning edge I8 is also sleeved with an elastic hoop 11 used for gathering each fastening piece.
