Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories and equipment, in particular to a low-temperature resistant rubber bushing at the front end of an automobile. Background Art

[0002] Automobile shock-absorbing rubber bushings are automobile shock-absorbing components, mostly installed on automobile swing arm components, and are used to connect parts such as shafts and holes where shock absorbers are installed on automobiles. Among them, rubber generally uses natural rubber and chloroprene rubber, but also materials such as nitrile rubber, silicone rubber and butyl rubber. Bushings are accessories used outside mechanical parts to achieve sealing, wear protection and other functions. They refer to ring sleeves that act as gaskets. Automobile bushings generally consist of three parts: a metal shell, an intermediate rubber sleeve and an inner tube. The three parts are connected together to form a complete bushing.

[0003] When the existing rubber bushing is used, the bushing is generally directly and firmly connected to the outside of the metal shell, which is not easy to remove. Moreover, after long-term wear and tear, the rubber bushing is more closely attached to the inner tube, and the edge becomes thinner, making it more difficult to remove.

[0004] This case was created to solve the above problems. Utility Model Content

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: a low-temperature resistant rubber bushing for the front end of a car, comprising an inner tube and a rubber sleeve, the inner tube is provided with a rubber sleeve tightly wrapped around the inner tube, the end of the inner tube is provided with a convex ring, the inner side wall of the inner tube is provided with a protruding circular ring, an auxiliary separation structure is provided above the inner tube, and the auxiliary separation structure includes a top cover, a connecting column, and a spring.

[0009] Preferably, one end portion of the spring is fixedly connected to the bottom surface of the top cover. The top cover is circular, and a plurality of connecting columns are circumferentially provided on the bottom surface. The connecting columns are rotatably connected to the bottom surface of the top cover.

[0010] Preferably, the other end of the connecting column is fixedly connected to an external expansion piece, the bottom of the external expansion piece is an arc that contracts downward, the bottom of the external expansion piece is perpendicular to the convex ring, and parallel to the side wall of the inner tube.

[0011] Preferably, the connection between the connecting column and the external expansion piece is fixedly connected by a clip and a piece, and the surface of the end of the external expansion piece is smooth.

[0012] Preferably, the arc angle of the end portion of the outer expansion piece is 30 degrees, the arc-shaped slope of the end portion of the outer expansion piece is outward, and the lowest point is located on the same straight line as the connection between the rubber sleeve and the inner tube.

[0013] (3) Beneficial effects

[0014] After adopting the above technical solution, the utility model has the following advantages compared with the existing technology: the utility model provides a low-temperature resistant rubber bushing for the front end of an automobile, which can support one end of the spring by arranging a protruding ring in the inner wall of the inner tube. When the spring is placed on it, the top cover is pressed downward to compress the spring, and the connecting column moves downward and outward, so that the end of the outer expansion piece extends into the rubber sleeve to expand the rubber sleeve, and the rubber sleeve is expanded. The bottom of the outer expansion piece is in an arc shape, so that the rubber sleeve can be easily expanded without damaging the rubber sleeve, making it easy to remove and separate.

[0019] The present invention will be further described in detail below through the accompanying drawings and examples.

[0020] like Figure 1-3 As shown: A low-temperature resistant rubber bushing for the front end of an automobile, comprising an inner tube 1 and a rubber sleeve 2. The inner tube 1 is provided with a rubber sleeve 2 that tightly wraps the inner tube 1. The end of the inner tube 1 is provided with a convex ring 3. The inner side wall of the inner tube 1 is provided with a protruding circular ring. An auxiliary separation structure is provided above the inner tube 1. The auxiliary separation structure comprises a top cover 4, a connecting column 5, and a spring 7. When the rubber sleeve 2 needs to be removed, the auxiliary separation structure is placed directly above the inner tube 1, and the lower end of the spring 7 is placed on the circular ring inside the inner tube 1. Then, the top cover 4 is pressed downward, and the spring 7 contracts. At this time, the connecting column 5 moves downward, and the bottom end of the outer expansion piece 6 is inserted into the connection between the rubber sleeve 2 and the inner tube 1. As the top cover 4 is pressed downward, the connecting column 5 rotates outward to drive the outer expansion piece 6 to expand, pushing the rubber sleeve 2 outward. At this time, the rubber sleeve 2 can be easily removed.

[0021] One end of a spring 7 is fixedly connected to the bottom surface of the top cover 4. The top cover 4 is circular, and a plurality of connecting columns 5 are provided circumferentially on the bottom surface. The connecting columns 5 are rotatably connected to the bottom surface of the top cover 4. Pressing the top cover 4 downward drives the connecting columns 5 to rotate outward and then drives the outward expansion piece 6 to expand outward.

[0022] The other end of the connecting column 5 is fixedly connected to an external expansion piece 6. The bottom of the external expansion piece 6 is an arc that contracts downward to ensure that the rubber sleeve 2 will not be damaged when the external expansion piece 6 expands the rubber sleeve 2 outward. The bottom of the external expansion piece 6 is perpendicular to the convex ring 3 and parallel to the side wall of the inner tube 1.

[0023] The connection between the connecting column 5 and the outer expansion member 6 is fixedly connected by a clamp and a member 9. The surface of the end of the outer expansion member 6 is smooth, and burrs and sharp corners are removed, which further prevents damage to the rubber sleeve 2.

[0024] The arc angle of the end of the outer expansion piece 6 is 30 degrees, and the arc slope of the end of the outer expansion piece is outward. The lowest point is on the same straight line as the connection between the rubber sleeve 2 and the inner tube 1. The rubber sleeve 2 is made of vulcanization and sandblasting processes as a whole to ensure that it can remain stable at low temperatures.

[0025] The above description is based on the embodiments for inspiration. Through the above description, relevant personnel can make various changes and modifications without departing from the scope of the invention. The technical scope of this new type of use is not limited to the content of the specification, and its protection scope must be determined according to the scope of the claims.
