Description

Technical Field

[0001] The utility model relates to the technical field of bushings, and specifically relates to a vehicle connecting rod bushing with adjustable clearance. Background Art

[0002] In the automotive chassis system, the connecting rod bushing, as a key load-bearing and connecting component, is widely used to connect various components of the automotive chassis, such as the suspension system, steering system, etc. The traditional design of the connecting rod bushing usually has a fixed outer diameter and inner diameter, which makes it only meet specific dimensional requirements during the installation process, lacking sufficient flexibility and being difficult to adjust according to actual usage conditions.

[0003] Furthermore, as the vehicle usage time increases, the connecting rod mounting holes in the chassis system will be worn due to factors such as repeated impacts, vibrations, frictions, and high-load operations, resulting in an increase in the hole diameter. When the size of the connecting rod mounting hole changes, the original outer diameter and inner diameter of the bushing often cannot match it, causing a gap between the bushing and the mounting hole. An excessive gap will not only affect the stability and durability of the bushing, but also may lead to poor contact between the bushing and the mounting hole, increasing friction and wear, and further affecting the safety and comfort of the automotive chassis.

[0004] Since the outer diameter and inner diameter of the traditional bushing are fixed and cannot be adjusted according to the worn hole diameter, when the connecting rod mounting hole is worn, it is necessary to replace the bushing and the connecting rod together, resulting in an increase in maintenance costs. Summary of the Utility Model

[0005] Aiming at the above deficiencies existing in the prior art, the purpose of the utility model is to provide a bushing with flexible use and reduced maintenance costs.

[0006] The technical solution adopted by the utility model to achieve the above purpose is: a vehicle connecting rod bushing with adjustable clearance, including an outer cylinder, an inner cylinder, and a rubber spring sleeve. The rubber spring sleeve is fixedly connected to the inner wall of the outer cylinder, and the inner cylinder is fixedly connected to the inner wall of the rubber spring sleeve. The outer cylinder is matched with an outer clearance filling sleeve, and the inner cylinder is matched with an inner clearance filling sleeve. An insertion groove A is provided on the outer wall of the outer cylinder, and an insertion portion A is provided on the outer clearance filling sleeve. The insertion portion A is installed in cooperation with the insertion groove A.

[0007] An insertion groove B is provided on the inner wall of the inner cylinder, and an insertion portion B is provided on the inner clearance filling sleeve. The insertion portion B is installed in cooperation with the insertion groove B.

[0008] There are multiple groups of the outer clearance filling sleeves and the inner clearance filling sleeves, and the thicknesses of the multiple groups of the outer clearance filling sleeves and the inner clearance filling sleeves are different.

[0009] In the above technical solution, both the insertion slot A and the insertion slot B adopt a T-shaped groove structure, and both the insertion part A and the insertion part B adopt a T-shaped block structure;

[0010] One end of both the insertion slot A and the insertion slot B is open, and the other end is closed;

[0011] A fastening part A is provided on the outer cylinder to match the insertion part A, and a fastening part B is provided on the inner cylinder to match the insertion part B.

[0012] In the above technical solution, the fastening part A includes a fastening platform A and a fastening bolt A. One end of the insertion part A is fixedly connected to the fastening platform A. A through hole A is provided on the fastening platform A, and a threaded hole A is provided on the outer cylinder to match the through hole A. The fastening bolt A passes through the through hole A and is threadedly connected to the inside of the threaded hole A.

[0013] In the above technical solution, the fastening part B includes a fastening platform B and a fastening bolt B. One end of the insertion part B is fixedly connected to the fastening platform B. A through hole B is provided on the fastening platform B, and a threaded hole B is provided on the inner cylinder to match the through hole B. The fastening bolt B passes through the through hole B and is threadedly connected to the inside of the threaded hole B.

[0014] In the above technical solution, friction stripes are provided on the inner wall of the outer clearance filling sleeve and the outer wall of the inner clearance filling sleeve.

[0015] The beneficial effects of the present utility model: An outer clearance filling sleeve can be installed on the outer cylinder of the bushing as required, or an inner clearance filling sleeve can be installed on the inner cylinder of the bushing as required. In this way, the outer diameter or the inner diameter of the bushing can be adjusted, so that the bushing can meet the usage requirements of different vehicles, and it has good flexibility. Moreover, when replacing the automotive connecting rod bushing, if the installation hole of the connecting rod has a larger hole diameter due to wear, by replacing the above-mentioned outer clearance filling sleeve or inner clearance filling sleeve, the connection stability between the connecting rod installation hole and the bushing can be ensured, and the situation of directly replacing the connecting rod and increasing the replacement cost can be avoided.
