Abstract

The invention relates to a lining structure, which is provided with two lining sleeves with independent structures, wherein the two lining sleeves with independent structures are fixedly connected through sleeves at the upper end and the lower end to form an integral lining sleeve, so that the integral lining sleeve cannot be separated when the lining sleeve is stressed. Each bushing consists of a rubber inner tube, a rubber main body and a rubber outer tube, and the rubber inner tube and the rubber outer tube are connected into a semicircular bushing structure through the rubber main body. The bushings with two independent structures meet the requirement of loading performance by changing the main rubber structure and the rubber hardness and the formula respectively. The two sleeves are connected with the rubber inner tube in an interference fit manner, so that the integral bushing can be prevented from being separated by the stressed rubber inner tube. Any one of the two bushings with independent structures is provided with a clamping groove structure on the rubber inner pipe for accurately positioning the pressing direction of the bushing. The invention has the advantages of simple structure, low requirements on production process and skeleton manufacturing, and the like, and can solve the defect that the existing bushing cannot greatly debug rubber performance with larger difference on two sides.

Description

a bushing structure

technical field

The invention relates to a bushing structure, which belongs to the technical field of auto parts product structure.

Background technique

In the process of automobile development, with the different requirements of automobile types and performance, there are more and more performance requirements for bushing products, and more and more technologies are developed accordingly. In order to meet the customer's loading and performance requirements, it is necessary to design a bush with different performance in different directions, and the performance requirements in different directions are quite different. The existing technology can meet the production and processing, and the existing production technology and skeleton structure can meet the manufacturing requirements. In order to meet the above requirements, a new bushing structure needs to be proposed.

Contents of the invention

The object of the present invention is to propose a bushing structure which meets various performance requirements.

In order to achieve the above object, the technical solution of the present invention is: a bushing structure with two independent bushings, and the two independent bushings are fixedly connected by the upper and lower ends of the bushing to form an integral bushing to ensure When the bushing is stressed, the integral bushing will not separate.

Further, each bushing is composed of a rubber inner tube, a rubber main body, and a rubber outer tube, and the rubber inner tube and the rubber outer tube are connected through the rubber main body to form a semicircular bushing structure.

Further, the two bushings with independent structures can meet the loading performance requirements by changing the rubber main structure, rubber hardness and formula respectively.

Further, the interference fit connection between the two bushings and the rubber inner tube can prevent the rubber inner tube from being separated by force on the whole bush.

Further, any one of the rubber inner tubes of the two independent bushings is provided with a slot structure for precise positioning of the pressing direction of the bushing.

Compared with the prior art, the bushing structure of the present invention has the following beneficial effects:

1. The present invention can adjust the rubber structure of the main spring bodies on both sides according to the performance requirements of different road conditions of customers.

2. The invention can adjust the rubber hardness and formula of the main spring bodies on both sides according to the performance requirements of different road conditions of customers.

3. The present invention can accurately locate through the slot in the middle of the inner tube, so as to ensure the accurate assembly of the bushing and ensure the performance in the specified direction.

4. The present invention avoids the problem of separation of inner tubes under stress of the bushing through the interference fit structure of the two inner tubes and the casing.

Detailed ways

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

The present invention is a brand-new bushing structure, as shown in Fig. 1, Fig. 2 and Fig. 3, the present invention mainly solves bushings with large differences in performance requirements in different directions.

The bushing structure is composed of bushing A and bushing B, through the interference fit with the bushing a2 and bushing b8, to ensure that the bushing will not be separated when the bushing is stressed; bushing A and bushing B are independent The two bushing structures can adjust the rubber structure of the bushing (such as diameter, radian, thickness, etc.) Press-fitting direction of the bushing. A brand new bushing structure is realized through the above design.

Wherein, bushing A is composed of A rubber inner tube 1 , A rubber main body 3 , and A rubber outer tube 4 . The A rubber inner tube 1 and the A rubber outer tube 4 are connected into one body through the A rubber main body 3 . Bushing B is composed of B rubber inner tube 5, B rubber main body 6, and B rubber outer tube 7. The B rubber inner tube 5 and the B rubber outer tube 7 are connected into one body through the B rubber main body 6 .

When the bushing A is connected with the bushing B, the semicircular A rubber inner tube 1 and the semicircular B rubber inner tube 5 are merged, and then the upper sleeve a2 and the lower sleeve b8 are fixedly connected into one body.

A rubber inner tube 1 or B rubber inner tube 5 has a card slot structure.

Structural description of the present invention is as follows:

(1) The present invention can adjust the rubber structure of the main spring bodies on both sides according to the performance requirements of different road conditions of customers;

(2) The present invention can adjust the rubber hardness and formula of the main spring bodies on both sides according to the performance requirements of different road conditions of customers;

(3) The present invention can accurately locate the bushing through the slot in the middle of the inner tube, thereby ensuring the accurate assembly of the bushing and ensuring the performance in the specified direction;

(4) The present invention avoids the problem of separation of the inner tube under stress of the bush through the interference fit structure of the two inner tubes and the casing.

In summary, the present invention can flexibly adjust the performance of the bushings on both sides through the two-petal bushing structure, and because the bushing has a simple structure, it does not involve a difficult production process, and the traditional vulcanization mold equipment and technology can meet the production requirements. need. The structure of the product is simple, and the structure and matching process of outsourced parts are very common. While reducing the difficulty of the manufacturing process, the invention can conveniently adjust the performance requirements on both sides of the bushing, and greatly improves the debugging of the existing bushing.
