Description

Low NVH and high durability's bandage formula lug

Technical Field

The utility model relates to a lug technical field especially relates to a bandage formula lug of low NVH and high durability.

Background

Lifting lugs on the existing market are mostly of pure rubber structures or metal-containing vulcanization molding structures. The pure rubber structure, the lug can be stretched by a wide margin under the extreme condition, and its durability can descend by a wide margin. The metal-containing vulcanization molding structure relates to the problems of large volume, heavy weight and high cost, does not meet the requirement of lightweight design in the current vehicle market, and simultaneously needs to carry out anticorrosive treatment on the metal surface after the completion of products due to the fact that most of the metal-containing vulcanization molding structure uses iron metal, so that the cost of the products is further increased. In addition, in the process of treating the metal surface, the risk of environmental pollution is easily generated.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of above-mentioned technique, and provide a bandage formula lug of low NVH and high durability.

The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: the utility model provides a low NVH and high durability's bandage formula lug which characterized in that: the rubber binding belt comprises a polyester fiber binding belt and a rubber body, wherein a lifting hole is formed in the rubber body, and a plurality of pressing lines are arranged at the joint of the polyester fiber binding belt and are assembled around the rubber body.

Preferably, thin arms with arcs are arranged on two sides of the rubber body, and the polyester fiber binding bands penetrate through the space between the thin arms and the rubber body.

The utility model has the advantages of simple structure, reasonable design, light weight, and capability of meeting the requirements of low rigidity and high durability of customers. Thereby obtaining good driving comfort and safety of the exhaust system; because the polyester fiber binding band is used as a limit, the durability of the product is greatly improved, the manufacturing cost of the product is reduced, the product has good quality, and the product can be better appreciated by customers. Meanwhile, the new product design and process application greatly improve the application range of the product, greatly improve the company technology and provide precious experience for the development of similar products in the future.

Detailed Description

The following detailed description of the preferred embodiments of the present invention is provided in connection with the accompanying drawings. As shown in figures 1-5, a bandage type lifting lug with low NVH and high durability is formed by assembling a polyester fiber bandage 1 and a rubber body 2. A plurality of pressing lines are arranged at the joint sewing position of the polyester fiber binding band and assembled around the rubber body, so that the rubber body does not have too large stretching amount and plays a certain limiting role; the destructive power of bandage can exceed 2000N to when the lug bearing, the bandage has shared most gravity, has promoted the durability of lug greatly. The manufacturing process of the polyester fiber bandage is mature and stable, the production efficiency is high, and the cost is low. The rubber body material adopts ethylene propylene rubber with low price, and the material can meet the working condition requirement of the exhaust system for a long time at high temperature. Some optimization is also carried out on the structural design of the product: in order to meet the requirement of low rigidity in the Z direction, the supporting arm parts on the two sides of the product are designed into thin arms 3 with certain radian, the thickness of the thin arms is only close to the wall thickness of the assembling holes, so that the durability can be improved, and the stress of the lifting lugs is uniformly distributed to each rubber stress point.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.

Claims (1)

1. The utility model provides a low NVH and high durability's bandage formula lug which characterized in that: the rubber body is provided with a lifting hole, and a plurality of pressing lines are arranged at the joint sewing position of the polyester fiber binding band and assembled around the rubber body; thin arms with radians are arranged on two sides of the rubber body, and the polyester fiber binding band penetrates through the space between the thin arms and the rubber body.
