Embodiment 1

[0024] Embodiment 1 is: a new inner skeleton of the bushing, refer to image 3 with Figure 4 As shown, it includes a bushing connecting pipe 1a and a connecting flange 1b. The connecting flange 1b is provided with a fastening structure 2 integral with it. The fastening structure 2 includes a fastening pad 2a integrally provided with the flange; The solidity of the gasket 2a and the connecting flange 1b and the bushing connecting pipe 1a are uniformly arranged so as to avoid slipping and loosening; refer to Figure 5 As shown, the thickness of the fastening pad 2a is at least 1mm, which can ensure the wear resistance of the fastening pad 2a. The strength of the fastening pad, the radius of the first half-round corner 2a1 is 1R, and the second half-round corner 2a2 is 0.5R; so that the first half-round corner 2a1 and the second half-round corner 2a2 are tangent to each other, so that the fastening pad 2a and the connecting flange 1b The strong integral connection improves the...

Embodiment 2

[0026] The second embodiment is: a new inner skeleton of the bushing, refer to Image 6 , Figure 7 with Figure 8 As shown, the fastening structure 2 also includes a friction assembly 2b, which is arranged on the A-fitting surface 1a0 of the fastening pad around the bushing connecting pipe 1a, thereby increasing the friction of the A-fitting surface 1a0 of the fastening pad, so that it is compatible with The mounting surfaces of the mounting bolts are tightly locked together to avoid slipping and loosening; the friction assembly 2b includes at least one circle of friction grooves 20, the cross section of the friction grooves 20 is a tooth-like structure, the depth of the friction grooves 20 is 0.1mm, and the number of friction grooves 20 5 friction grooves 20 are evenly distributed on the A assembly surface 1a0 of the fastening pad in turn, and the tooth spacing of each friction groove 20 is 0.5mm; refer to Figure 9 As shown, four friction grooves 20 are also provided on t...

Abstract

The invention relates to a novel bush inner framework. The novel bush inner framework comprises a bush connecting pipe and a connecting flange. A fastening structure integrated with the connecting flange is arranged on the connecting flange. The fastening structure comprises a fastening pad integrated with the connecting flange. According to the novel bush inner framework, the fastening structureis arranged on the connecting flange, particularly, the fastening pad integrated with the connecting flange, and when the fastening pad and a mounting bolt are locked and connected, the fastness thatthe fastening pad, the connecting flange and the bush connecting pipe are integrally arranged is utilized, and therefore the novel bush inner framework is prevented from slipping and loosening; and the reliable fastness of the novel bush inner framework is guaranteed.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a novel bushing inner frame. Background technique [0002] The inner frame of the bushing is a kind of auto parts, such as figure 1 Is the existing bush inner skeleton structure; such as figure 2 The inner skeleton of the bush shown in the figure is connected with the outer jacket through the rubber lining to form a shock-absorbing bush; while the shock-absorbing bush is connected with the front frame or the rear frame mainly through the upper and lower installation ends of the inner skeleton of the bush. The shock-absorbing bush is connected to the vehicle frame by being connected with mounting bolts. However, the fastening performance of the existing inner frame of the bushing is poor, and the upper and lower mounting end faces are flat and the mounting bolts are prone to slipping, loosening and unable to be locked, resulting in serious swings between the shock-absorbing ...
