Abstract

The utility model relates to the technical field of swing arms in automobile suspension systems, in particular to a shock absorbing bushing of an automobile swing arm. The shock absorbing bushing comprises an outer shell, a core pipe arranged in the outer shell and shock absorbing rubber arranged between the core pipe and the outer shell. The core pipe and a shaft at the end of the swing arm are fastened, a mounting hole fastened with an auxiliary automobile frame is formed in the face of the outer shell, the shock absorbing bushing and the auxiliary automobile frame are fastened through the mounting hole, the defect that a gap is formed in the auxiliary automobile frame is overcome, control over the size of the whole swing arm is convenient, and assembly precision is improved.

Description

The shock absorbing bushing of automobile swing arm

Technical field

The utility model relates to automobile swing arm technical field, particularly a kind of shock absorbing bushing of automobile swing arm.

Background technology

Swing arm is widely used on the independent front suspension of car, and for connecting between vehicle body and wheel flutter, swing arm one end is connected with subframe or vehicle body on vehicle body by shock absorbing bushing, and the other end is locked with ball end and steering swivel.In prior art, shock absorbing bushing in front suspension swing arm comprise with the shock absorbing bushing of the front assembling of automobile accessory frame and with subframe after the rear shock absorbing bushing of some assembling, two shock absorbing bushings and subframe form a kind of elastomeric connection, are mainly to play effects such as subframe support and dampings.

In prior art, structure with a kind of integral body of shock absorbing bushing of point before automobile accessory frame (headstock direction) assembling, shock absorbing bushing integral body is column, comprise and be arranged on outside shell in a tubular form, the sheathed core pipe in the inside of shell, between core pipe and shell, vulcanize yielding rubber, realize the damping of the fastening and swing arm of core pipe and shell, damping lining is whole to be set in the mounting sleeve arranging on swing arm body, the shell of shock absorbing bushing is pressed in the mounting sleeve of swing arm by press-loading device, thereby realize fixing, for the datum line that the line of centers of shock absorbing bushing and the mounting sleeve of swing arm are arranged overlaps (shown in Fig. 1 and Fig. 2, line of centers C is the datum line of mounting sleeve), thereby realize the assurance to the whole fitted position of swing arm, in prior art, need to measure by the length that measuring tool stretches out the mounting sleeve two ends in swing arm to damping sleeve pipe, so that the mounting sleeve datum line in the line of centers of shock absorbing bushing and swing arm overlaps, when assembling, the shock absorbing bushing in existing this swing arm wastes time and energy, the precision of measuring cannot ensure.

Utility model content

The purpose of this utility model is to provide a kind of shock absorbing bushing of automobile swing arm, with swing arm before point arrange mounting sleeve assembling time, guarantee that the line of centers of shock absorbing bushing and the datum line of the mounting sleeve in swing arm overlap.

For realizing above object, the technical solution adopted in the utility model is: a kind of shock absorbing bushing of automobile swing arm, the shell that comprises circular tube shaped, core pipe is set in shell, the yielding rubber arranging between outer shell-and-core pipe, one side end of described shell is arranged to flange laterally, when the pairing of two shock absorbing bushings is pressed into the mounting sleeve in swing arm, the side end of flange and mounting sleeve against.

Compared with prior art, there is following technique effect in the utility model: when two identical shock absorbing bushing pairings are pressed on the mounting sleeve in swing arm, the flange arranging on shock absorbing bushing shell and the side end of mounting sleeve against time, the line of centers of two shock absorbing bushings and the datum line of the mounting sleeve in swing arm overlap, shock absorbing bushing is simple and practical, without measuring tool, measure, assembly precision is improved.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model and swing arm assembling;

Fig. 2 is the A-A view of Fig. 1.

The specific embodiment

Below in conjunction with Fig. 1 and Fig. 2, the utility model is done to further narration:

A kind of shock absorbing bushing of automobile swing arm, the shell 10 that comprises circular tube shaped, the interior core pipe 20 that arranges of shell 10, the yielding rubber 30 arranging between shell 10 and core pipe 20, one side end of described shell 10 is arranged to flange 11 laterally, when two shock absorbing bushing pairings are pressed into the mounting sleeve B in swing arm, the side end of flange 11 and mounting sleeve B against, shown in Fig. 2, when two identical shock absorbing bushing pairings are pressed on the mounting sleeve in swing arm, the flange 11 arranging on shock absorbing bushing shell and the side end of mounting sleeve against time, the line of centers of two shock absorbing bushings and the datum line of the mounting sleeve in swing arm overlap, shock absorbing bushing is simple and practical, without measuring tool, measure, assembly precision is improved.

Further, as preferred version of the present utility model, the both side ends that shell 10 is stretched out at described core pipe 20 two ends, when two shock absorbing bushing pairings are pressed into mounting sleeve B, the end face of the core pipe 20 stretching out near or mutually recline, core pipe 20 end faces that are positioned at flange 11 sides are arranged to annular knurl face, when swing arm is assembled on automobile accessory frame, to fixing passing through by being plugged on the bolt of 20 li of core pipes of putting before swing arm, when nut and bolted, the picture that rolls of the end face of nut and core pipe 20 end faces reclines, solid and reliable.

Finally, described flange 11 is arranged along the anchor ring of the end of shell 10, is consulted Fig. 2, flange 11 is round-corner transition with shell 10, avoid stress to concentrate, prevent in process that shock absorbing bushing is pressed into, when flange 11 is subject to the power of mounting sleeve B side end excessive and fracture failure.
