Abstract

The utility model discloses a vehicle used swing arm structure, which includes an upper swing arm and a lower swinging arm. The lower swing arm includes a forward swing arm lever and a backward swing arm lever. The forward swing arm lever and the backward swing arm lever form a shape like a Chinese character ''Ba'' with a pedestal equipped on the wider end. The pedestal is connected to the frame with a damping rubber cover inside the pedestal. ''Ba'' shape narrow ends of the forward swing arm lever and the backward swing arm lever are connected to the long sleeve that is hinged to the axle tree. The damping rubber cover can be installed inside the long sleeve. ''Ba'' shape narrow ends of the forward swing arm lever and the backward swing arm lever are installed with a damper seat used to install the damping element. Vehicle used swing arm structure of the utility model can effectively constraint the longitudinal traverse of a suspension swing arm, in particular to that of the outer end of the swinging arm as well as that of a wheel.

Description

The Swing arm for vehicle structure

Technical field

The utility model relates to a kind of Swing arm for vehicle, a kind of specifically swing arm structure that is applied on the vehicles such as farmer's car, trac..

Technical background

At present, the forward mounting swing arm of using on many vehicles is to adopt the four-bar linkage swing arm.Yet this swing arm structure generally has the shortcoming that rod member is yielding, rod member connects complexity and the easy generation of linkwork is become flexible.Illustrated in figures 1 and 2ly be existing a kind of four connecting rod suspension arms structures, the principle of work of this structure is as follows: when the effect that the power that will push away before hanging is arranged under the effect of wheel 101 at propulsive effort, when wheel braking or when running into obstacle, suspension can be subjected to the effect of thrust backward.The hinge-point of pumping arm action 102,103 can not active constraint hang to Y direction (being front and rear direction) mobile.Existing method normally adopts vertically (also being Y direction, fore-and-aft direction) stabilizer rod constraint suspension and wheel to vertically move.For the less vehicle of some free spaces, bring difficulty for the layout of longitudinal stability bar.Therefore, vertically moving of constraint suspension and wheel how reduced again as far as possible to the taking of finite space, and just seems very necessary.

Summary of the invention

For overcoming the above-mentioned technological deficiency of existing product, the utility model provides a kind of simple in structure, novel suspension arms structure of constraint failure-free, but active constraint suspension arms vertically moving of swing arm outer end and wheel particularly.

The technical solution adopted in the utility model is as follows: a kind of Swing arm for vehicle structure, comprise top link and following swing arm, and described swing arm down comprises forward swing armed lever and rear-swing arm bar:

The forward swing armed lever becomes " eight " font with the rear-swing arm bar;

The forward swing armed lever becomes the wide end of " eight " font to be respectively equipped with bearing with the rear-swing arm bar, bearing is connected on the vehicle frame; Further bearing can be microscler bearing, the interior damping gum cover of adorning.

The forward swing armed lever becomes the narrow end of " eight " font to be connected long putting with the rear-swing arm bar, long cover is hinged on the axletree; Can adorn the damping gum cover in the further long cover.

Become the narrow end of " eight " font to be provided with shock absorber bearing with the rear-swing arm bar at the forward swing armed lever, be used to install damper element.

The utility model adopts swing arm under " eight " font, but swing arm is the moving of X, Y, three directions of Z down in the actv. restriction, and restriction swing arm down makes down the swing arm outer end can only swing up and down together with wheel around the rotation of X, Z axle.Because swing arm makes down swing arm the inner improve greatly around the constraint strength that the Z axle rotates together with wheel under " eight " font, can satisfy the travel requirement of vehicle under various pavement conditions and operating mode.Simultaneously,, need not to adopt again the longitudinal stability pull bar, can further reduce rod member quantity, expendable weight, simplified structure, and save installing space, make design more reasonable owing to adopt swing arm under " eight " font.

Description of drawings

Fig. 2 is the cutaway view of following swing arm among Fig. 1;

Fig. 3 is the structural representation of swing arm under the utility model Swing arm for vehicle.

The specific embodiment

As shown in Figure 3, a kind of Swing arm for vehicle structure of the present utility model comprises two preceding armed lever 201 and back armed levers 202 that connect into " eight " font.Forward swing armed lever 201 is respectively equipped with bearing 204,205 with the wide end of 202 one-tenth on rear-swing arm bar " eight " font, and described bearing can be microscler bearing.Bearing 204,205 is hinged on the vehicle frame 104 by gum cover 207.

Swing arm bar 201 and bearing 204, swing arm bar 202 and bearing 205 are by being welded to connect.Be provided with damping gum cover 207 in the bearing 204,205, this damping gum cover 207 is connected for interference with bearing 204,205.The narrow end of forward swing

armed lever

201 and 202 one-tenth on rear-swing arm bar " eight " font is welded on the two ends of long cover 203 respectively, and long cover 203 is hinged on the axletree 105.Also be provided with two damping gum covers 208 in the long cover 203, this damping gum cover 208 also is connected for interference with long cover 203 ends.Forward and backward swing arm bar 201,202 overlaps " eight " font bonded assembly near also being welded with shock absorber bearing 206 near the long cover with long, is used to install damper element.
