Connecting rod ball round pin rotation-proof structure in, through set up the stopper on the dead lever and the mounting hole external fixation sets up the limiting plate, when tightening the nut, the limiting plate can play to the ball round pin and prevent changeing limiting displacement, the nut installation of being convenient for and the control of tightening moment.

Description

Connecting rod ball round pin rotation-proof structure

Technical Field

The utility model relates to a vehicle structure especially relates to a connecting rod ball round pin rotation-proof structure.

Background

As shown in fig. 1, in the prior art, a mounting bracket 3 is fixedly provided on a damper cylinder 2, a mounting hole 31 is opened on the mounting bracket 3, and a fixing rod 11 of a ball pin 1 of a connecting rod passes through the mounting hole 31.

The end of the fixing rod 11 has an inner hexagonal groove, and is fixed by an inner hexagonal tool when the nut is tightened, so as to prevent the ball pin from rotating. The socket head tool for fixing the ball pin is not common and the structure can not tighten the nut by using a torque wrench, so that the tightening torque of the nut can not be controlled. If the tightening torque is too large, threads of the nut or the ball pin can be damaged, if the tightening torque is too small, the nut can be loosened, the ball pin 1 with the connecting rod moves back and forth on the mounting bracket 3, the effect of the stabilizer bar is reduced or even disappears, and the driving safety is affected.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to prior art's drawback provides a connecting rod ball round pin rotation-proof structure.

The connecting rod ball pin anti-rotation structure comprises a mounting bracket fixedly arranged on a shock absorber cylinder barrel and a ball pin arranged on a mounting hole of the mounting bracket, wherein the ball pin is provided with a fixed rod for penetrating into the mounting hole, and a limit block is arranged on the fixed rod;

a limiting plate is fixedly arranged outside the mounting hole;

when the fixed rod penetrates into the mounting hole, the limiting block clamps the limiting plate.

Connecting rod ball round pin rotation-proof structure in, seted up on the limiting plate with stopper complex prevents that the hole.

In the anti-rotation structure for the connecting rod ball pin of the utility model, the limiting block is in a long circle shape, a triangle shape or a hexagon shape;

the anti-rotation holes are long round holes, triangular holes or hexagonal holes correspondingly matched with the limiting blocks.

Connecting rod ball round pin rotation-proof structure in, through set up the stopper on the dead lever and the mounting hole external fixation sets up the limiting plate, when tightening the nut, the limiting plate can play to the ball round pin and prevent changeing limiting displacement, the nut installation of being convenient for and the control of tightening moment.

Drawings

FIG. 1 is a schematic view of a prior art connecting rod ball pin mounting arrangement;

FIG. 2 is a schematic view of the anti-rotation structure of the connecting rod ball pin of the present invention;

fig. 3 is an exploded view of the anti-rotation structure of the ball pin of the connecting rod of the present invention.

Detailed Description

The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.

As shown in fig. 2 and fig. 3, the anti-rotation structure for the ball pin of the connecting rod of the present invention comprises a mounting bracket 3 fixedly disposed on a cylinder 2 of the shock absorber and a ball pin 1 disposed on a mounting hole 31 of the mounting bracket 3, wherein the ball pin 1 has a fixing rod 11 for penetrating into the mounting hole 31, and a limiting block 5 is disposed on the fixing rod 11; a limiting plate 4 is fixedly arranged outside the mounting hole 31; when the fixing rod 11 penetrates into the mounting hole 31, the limiting block 5 clamps the limiting plate 4. Like this, when tightening the nut, limiting plate 4 can play the stop function of preventing changeing to the ball round pin, the nut installation of being convenient for and the control of tightening moment.

Particularly, the utility model discloses in, can open on the limiting plate 4 with stopper 5 complex prevents that hole 41. When the limiting block 4 is in an oblong shape, a triangular shape or a hexagonal shape, the anti-rotation hole 41 can also be an oblong hole, a triangular hole or a hexagonal hole correspondingly matched with the limiting block 5. That is, the stopper 4 is not limited to the above-mentioned shape, and it is only necessary to insert the stopper 5 into the stopper plate 4 so as not to rotate.

While the embodiments of the invention have been described above, it is not intended to be limited to the details shown, or described, but rather to cover all modifications, which would come within the scope of the appended claims, and all changes which come within the meaning and range of equivalency of the art are therefore intended to be embraced therein.
