Problems solved by technology

[0006] At the same time, after the torsion beam and the bushing are assembled, due to the deformation characteristics (swing) of the rubber during the movement, the outer metal tube of the bushing, the bushing sleeve of the torsion beam and the body sheet metal may cause abnormal noise

Embodiment Construction

[0030] The technical solutions of the present invention are described below through specific examples. The following examples are only exemplary, and can only be used to explain and illustrate the technical solutions of the present invention, and cannot be construed as limitations on the technical solutions of the present invention.

[0031] The introduction of rubber bushings in the suspension system can alleviate the vibration and impact from the road and ensure the stability of the handling. wear and tear. Compared with other parts, the rubber bushing also has the following advantages: the shape of the rubber is not limited, and the spring stiffness ratio in three directions can be properly selected; it can be easily combined with the metal parts firmly, so that the rubber bushing can withstand many The load in the direction not only simplifies the structure, but also reduces the mass of the vehicle; the internal friction of vulcanized rubber is larger than that of metal, a...

Abstract

The invention relates to a rubber bushing, which comprises an outer casing pipe, an inner casing pipe and bushing rubber. From one end to the other end, the outer casing pipe is sequentially provided with a guiding conical section, a front interference fit cylindrical section, an inner necking cylindrical section, a back interference fit cylindrical section and a press mounting bearing plane. The guiding conical section has a small top diameter and forms a cone structure. The inner necking cylindrical section has a smaller diameter than the interference fit cylindrical section. The metal end of the back interference fit cylindrical section is provided with an outward turnup, which forms the press mounting bearing plane. A rubber anti-collision layer is formed on the press mounting bearing plane. According to the technical scheme of the invention, through sectional design and interference fit of the outer casing pipe, no internal defects are generated in a press mounting assembly process, the press mounting tooling can be clear in positioning, the press mounting bearing surface is expanded, the influence of other controlling factors is small, and the potential interference abnormal sound is solved.

Description

technical field [0001] The invention belongs to the technical field of automobile bushings, in particular to a rubber bushing. Background technique [0002] At this stage, the connection between the chassis and the body is mostly a flexible connection, that is, a rubber bush connection. The connection between rubber bushings and sheet metal parts (twist beams, frame, etc.) mostly adopts an interference fit method, and tooling is used to ensure the quality of the fit. Most of this process uses a stroke assembly limit tooling mechanism (the control bush is pressed into the sheet metal part. journey). [0003] In the prior art, the bushing is generally made of an inner metal tube, an outer metal tube and rubber filling and vulcanization between the two, and its connection with the torsion beam is an interference fit (the diameter of the outer metal tube of the bushing is larger than that of the torsion beam bushing) The inner diameter of the tube depends on this interference ...
