Technical Field

[0001] The utility model relates to the technical field of rubber bushings, and more specifically, particularly to an automobile shock-absorbing rubber bushing. Background Art

[0002] The function of automobile shock-absorbing rubber bushings is to change the rigid connection of the automobile into a rubber connection or even a hydraulic shock-absorbing connection, thereby improving the ride comfort of the car, making shock-absorbing technology more and more used in automobiles.

[0003] Automobile rubber shock-absorbing bushings generally include three parts: a metal outer bushing, an intermediate rubber body and an inner bushing. The three parts are connected together to form a complete bushing. The common bushing process is to directly connect the metal outer bushing and the inner bushing through the intermediate rubber body. This design structure can easily lead to axial disengagement between the inner bushing and the outer bushing, resulting in poor safety and causing adverse effects.

[0004] In view of this, the existing problems are studied and improved, and a shock-absorbing rubber bushing for an automobile is provided, aiming to solve the problems and improve the practical value through this technology. Utility Model Content

[0010] As a further optimization of the technical solution, the baffle of the automobile shock-absorbing rubber bushing of the utility model is a circular plate-shaped structure, and the baffle is located below the pad through an inner lining tube.

[0011] As a further optimization of the technical solution, the top seat of the automobile shock-absorbing rubber bushing of the utility model is disc-shaped when viewed from above and inverted "T" shape when viewed from the side, and the lower part of the top seat is located in the internal position of the upper part of the outer bushing through a clearance fit sliding manner.

[0012] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0013] 1. The utility model is a shock-absorbing rubber bushing for automobiles.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figures 1 to 3 The utility model provides a specific technical implementation scheme of an automobile shock-absorbing rubber bushing:

[0023] A shock-absorbing rubber bushing for automobiles comprises: an outer bushing 1, a slot 2, a pad 3, a rubber bushing 4, a reinforcing rib 5, an inner bushing 6, a baffle 7, and a top seat 8; the inner wall around the outer bushing 1 is provided with a slot 2 in an integrated structure, and the pad 3 is welded to the lower position inside the outer bushing 1; the rubber bushing 4 is installed inside the upper part of the outer bushing 1 by a clearance fit, and the outer wall of the rubber bushing 4 is provided with a reinforcing rib 5 in an integrated structure; the inner bushing 6 is simultaneously connected to the inside of the pad 3 and the rubber bushing 4 by a clearance fit, and the baffle 7 is welded to the bottom end of the inner bushing 6; the top seat 8 is screwed to the top end of the inner bushing 6 by threads.

[0024] Specifically, the rubber bushing 4 is a disc-shaped structure with a circular hole in the middle, and a plurality of semicircular raised reinforcing ribs 5 are arranged in a circular array on the outer wall of the rubber bushing 4, and in combination with the specification Figure 3 As shown, the rubber bushing 4 is located below the top seat 8 and plays a supporting and shock-absorbing role for the top seat 8 and the inner liner 6 .

[0025] Specifically, the outer liner 1 is a cylindrical structure with a flange at the bottom, and a plurality of semicircular slots 2 are arranged in a circular array on the inner wall of the outer liner 1, and in combination with the instructions Figure 3 As shown, the lower part of the outer liner 1 reserves space for the inner liner 6 to move downward for shock absorption.

[0026] Specifically, the baffle 7 is a circular plate structure, and the baffle 7 is located below the pad 3 through the inner liner 6, and combined with the instructions Figure 3 As shown, the baffle 7 mainly prevents the inner liner 6 from escaping from the backing plate 3 in the outer liner 1 .

[0027] Specifically, the top seat 8 is disc-shaped when viewed from above and is in an inverted "T" shape when viewed from the side, and the lower portion of the top seat 8 is located in an inner position of the upper portion of the outer liner 1 by means of clearance fit sliding.

[0028] Specific implementation steps:

[0029] The working principle of the device is as follows: a shock absorbing structure is formed between the inner liner 6 and the top seat 8 at the top and the outer liner 1 through the rubber bushing 4, and at the same time, the baffle 7 is always located below the pad 3 to prevent the inner liner 6 from falling out, thereby improving the safety performance of the device.
