Description

Technical Field

[0001] The utility model relates to the technical field related to automobile triangle arm bushings, in particular to a bushing used on an automobile chassis control arm. Background Art

[0002] The automobile yoke is a swing arm used for balancing support when the car is driving on uneven roads. It swings to balance the support body and shock absorber, thereby reducing the impact force during driving. The working principle of the yoke is similar to that of a universal joint. It can still move in conjunction with the driving and driven parties when the relative positions of the driving and driven parties change. The automobile yoke bushing is the connecting component between the automobile yoke and the subframe. It has the function of shock absorption and wear reduction. It is usually located on the yoke and is an important part of the automobile suspension system.

[0003] For example, announcement number CN204340585U discloses a rear bushing for an automobile triangular arm, comprising a bushing frame, a middle-ring rubber sleeve fixed in the bushing frame, a bushing inner tube fixed in the middle-ring rubber sleeve, and an inner-ring rubber sleeve fixed in the bushing inner tube that has an interference fit with the triangular arm core shaft. By adding a rubber inner ring to the bushing inner tube, when the rubber inner ring is press-fitted with the triangular arm core shaft, the rubber inner ring undergoes elastic deformation to achieve an interference fit; at the same time, the cooperation between the hexagonal triangular arm core shaft and the inner surface of the hexagonal rubber inner ring can prevent the triangular arm core shaft and the bushing inner tube from rotating relative to each other. Compared with the interference fit between metals, the interference fit between the rubber inner ring and the triangular arm core shaft not only reduces the pressing force by more than 2 / 3, but also requires only simple tooling to complete disassembly and assembly during later maintenance. At the same time, the interference fit between the rubber inner ring and the triangular arm core shaft can effectively avoid the risk of damage to the surface coating of the triangular arm core shaft;

[0004] However, the prior art has problems such as poor lubrication effect at the connection between the bushing and the metal part, inconvenience in adding lubricating oil, easy loss of lubricating oil after addition, and difficulty in storage. The bushing's service life is reduced due to wear during long-term use. For example, the comparative patents listed above have such problems.

[0005] For this reason, we propose a bushing for automobile chassis control arm to solve the above problems. Summary of the Invention

[0006] The purpose of the utility model is to provide a bushing for an automobile chassis control arm, so as to solve the problems in the prior art proposed in the above background technology, such as poor lubrication effect at the connection between the bushing and the metal part, inconvenience in adding lubricating oil, easy loss of lubricating oil after addition, difficulty in storage, and reduced service life of the bushing due to wear during long-term use.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solutions: a bushing for a vehicle chassis control arm, comprising a bushing end and a bushing body, wherein the bushing end and the bushing body are integrally formed;

[0008] Also includes:

[0009] The lubricating mechanism is composed of a adding groove, a lubricating channel and a connecting port.

[0010] As a preferred technical solution of the present invention, the adding groove is opened at the right end of the bushing end.

[0011] By adopting the above technical solution, lubricating oil can be added to the adding groove by opening the adding groove at the right end of the bushing end.

[0012] As a preferred technical solution of the present invention, the lubrication channel is opened on the inner side of the bushing body, and the lubrication channel is arranged at equal angles in the bushing body.

[0013] By adopting the above technical solution, the lubrication channel is opened on the inner side of the bushing body, and the lubrication channel is set at equal angles in the bushing body. The lubricating oil in the lubrication channel can fully contact the metal parts, and has a good lubrication effect on the connection between the bushing and the metal parts.

[0014] As a preferred technical solution of the present invention, the adding groove is connected to the lubrication channel through a connecting port, and the lubrication channel is opened at the opening of the inner diameter of the right end of the bushing.

[0015] By adopting the above technical solution, the adding groove is connected to the lubrication channel through the connecting port, and the lubrication channel is opened at the opening of the inner diameter of the right end of the bushing. The lubricating oil can flow into the lubrication channel through the adding groove and the connecting port, and the addition is very convenient.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the bushing used on the triangular arm, through the provision of the lubrication mechanism, can allow the lubricating oil to flow through the addition groove and the connection port to the lubrication channel, and the lubricating channel can play a certain storage role for the lubricating oil, thereby increasing the lubrication time and reducing the number of times the lubricating oil is added. The lubricating oil in the lubrication channel can fully lubricate the connection between the metal part and the bushing, thereby ensuring lubrication when the polyurethane bushing contacts the metal, and increasing the service life of the product;

[0017] A lubrication mechanism is provided, which consists of an adding groove, a lubrication channel and a connecting port. After lubricating oil is added to the adding groove, the lubricating oil flows into the lubrication channel through the connecting port, which can play a certain role in storing lubricating oil, lubricating the metal parts and the bushing, and extending the service life of the bushing.
