Compared with the prior art, the utility model has the following beneficial effects:

The connecting arm can further buffer through the buffer springs, and meanwhile, the buffer springs close to the connecting arm can be extruded along the buffer springs, so that the buffer effect on the connecting arm is better, and because the buffer springs are compressed and have different degrees, the buffer springs are mutually coordinated and protected, the buffer springs cannot be compressed for a long time to play a role in buffering and are damaged, and the service life of the buffer assembly can be prolonged.

Drawings

Fig. 1 is a schematic structural view of a front axle knuckle arm according to an embodiment of the present utility model.

Fig. 2 is a schematic view of a buffer assembly in a front axle knuckle arm structure according to an embodiment of the present utility model.

In the above figures: the connecting device comprises a cross rod 1, a mounting piece 2, a connecting arm 3, a mounting groove 4, a mounting disc 5, a fixing ring 6, a connecting ring 7, a buffer ring 8, a first connecting block 9, a buffer spring 10, a second connecting block 11 and a fixing bolt 12.

Detailed Description

The technical scheme of the utility model is further described below with reference to the accompanying drawings and examples.

As shown in fig. 1-2, an embodiment of the present utility model provides a front axle knuckle arm structure, including:

The novel horizontal rod comprises a horizontal rod 1, wherein mounting pieces 2 are mounted at two ends of the horizontal rod 1, a mounting groove 4 is formed in the front end of the horizontal rod 1, the mounting groove 4 penetrates through the bottom of the horizontal rod 1, a mounting disc 5 is movably mounted in the mounting groove 4, a connecting arm 3 is mounted at the bottom of the mounting disc 5, a weight reduction groove is formed in the connecting arm 3 in a penetrating mode, and the mounting disc 5 is mounted in the mounting groove 4 through a bolt and swings in the direction perpendicular to the axial direction of the bolt;

A buffer assembly; the buffer component comprises a fixed ring 6 fixed at the bottom of the cross rod 1, and the fixed ring 6 is fixedly connected with the bottom of the cross rod 1 through a fixed bolt 12; the upper end of the connecting arm 3 is provided with a buffer ring 8 which is propped against the connecting arm, the buffer ring 8 is a rubber ring, and the buffer ring 8 is connected with the connecting ring 7 through viscose; the upper end of buffer ring 8 installs go-between 7, be fixed with a plurality of buffer springs 10 between go-between 7 and the solid fixed ring 6, a plurality of buffer springs 10 are annular array and distribute, gu fixed ring 6 is last fixedly connected with first connecting block 9, fixedly connected with second connecting block 11 on the go-between 7, buffer springs 10's both ends and first connecting block 9, second connecting block 11 fixed connection.

The detailed working process of the utility model is as follows:

1. When the connecting arm 3 swings at the mounting disc 5, the connecting arm 3 can squeeze the buffer ring 8, the connecting arm 3 can be buffered through the buffer ring 8 and the connecting arm 3 can be protected at the same time, so that the connecting arm 3 can not be contacted with the cross rod 1 to cause abrasion, and the connecting arm 3 swings to squeeze the buffer ring 8 and then squeeze the connecting ring 7, so that the buffer spring 10 squeezed at the connecting ring 7 is compressed, the connecting arm 3 can be further buffered through the buffer spring 10, and meanwhile, the buffer spring 10 near the side is also squeezed along, and the buffer effect on the connecting arm 3 is better;
