Description

Technical Field

[0001] The utility model relates to the technical field of automobile rear axle air chamber pads, in particular to an automobile rear axle air chamber pad. Background Art

[0002] The air chamber pad is a pad used on the rear axle housing of a car. The air chamber pad is an important part of the car's drive axle. The axle housing is affected by the impact load generated between the wheels and the ground, which may cause the axle housing to deform or break. Therefore, the air chamber pad is used.

[0003] For example, the publication number CN218197751U discloses an air chamber pad that is easy to install, including a pad body, a first docking block and a second docking block. The lower end of the pad body is provided with a first anti-skid plate at the front and rear, and the lower end of the pad body is provided with a second anti-skid plate at the left and right. The utility model overcomes the shortcomings of the prior art. By providing the first anti-skid plate and the second anti-skid plate, after the pad body is placed on the surface of the air chamber support plate, the inner walls of the first anti-skid plate and the second anti-skid plate will contact the side surface of the air chamber support plate, so that the first anti-skid plate and the second anti-skid plate limit the pad body to the upper end of the air chamber support plate. When a person uses a bolt to tighten the first docking hole, it is not easy to cause the placement position of the pad to move, so that the second docking hole on the pad and the docking hole on the air chamber support plate will not be confused, thereby improving the installation efficiency of the pad by the person.

[0004] During the installation process of the existing air chamber pad, it is first connected to the air chamber bracket and then fixed to the rear axle housing with bolts. However, this installation method is prone to loosening of the bolts due to stress, which in turn causes the position of the air chamber pad to shift, affecting the stability of the installation. Therefore, there is an urgent need to design an automobile rear axle air chamber pad. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] See also Figure 1-4 , an embodiment provided by the utility model:

[0023] An automobile rear axle air chamber pad, comprising:

[0024] The device body includes a backing plate body 100, a first anti-skid plate 110, a second anti-skid plate 111 and a welding block 119. The first anti-skid plate 110 and the second anti-skid plate 111 are respectively provided around the top of the backing plate body 100, and the welding block 119 is provided on the outside of the backing plate body 100:

[0025] An upper welding plate 122 is provided on the top of the pad body 100, and a lower welding plate 123 is provided on the bottom of the pad body 100. Docking blocks 126 are provided around the pad body 100, the upper welding plate 122 and the lower welding plate 123. A threaded hole 113 is provided on the docking block 126, and a bolt body 114 is provided inside the threaded hole 113. A first slot 116 is provided on the outside of the bolt body 114, and an insert block 115 is movably installed inside the first slot 116. A second slot 117 is provided on the outside of the upper welding plate 122. The insert block 115 and the first slot 116 are provided on the insert block 115. This design avoids the risk of the insert block 115 loosening due to long-term use, thereby improving the stability of its reinforcement.

[0026] Furthermore, a nylon rope 118 is fixedly installed on the outside of the bolt body 114, and the other side of the nylon rope 118 is fixedly connected to the outside of the plug block 115.
