[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with illustrations and specific embodiments.

[0026] like Figures 1 to 4 As shown, the utility model provides a shaft sleeve for automobile suspension, comprising a shaft sleeve body 1, a shaft sleeve body 1 having a shaft hole 2 for accommodating a rotating shaft, and further comprising:

[0027] A sealing ring groove 3, wherein a plurality of sealing ring grooves 3 are provided, and the plurality of sealing ring grooves 3 are respectively provided on the inner walls at both ends of the shaft sleeve body 1 and extend along the circumference of the shaft sleeve body 1. The sealing ring groove 3 is used to accommodate a sealing ring, and a first end of the sealing ring is located in the sealing ring groove 3, and a second end of the sealing ring is located on the contact surface between the shaft sleeve body 1 and the rotating shaft. Preferably, the sealing ring is a rubber sealing ring, and cooperates with the shaft sleeve body 1 and the rotating shaft to form a seal to prevent lubrication leakage;

[0028] A lubrication channel 4 is provided on the inner wall of the inner body of the sleeve, and lubricating oil can flow along the lubrication channel 4 and lubricate the contact surface between the sleeve body 1 and the rotating shaft, which helps to reduce friction and prevent overheating, thereby extending the service life of the sleeve;

[0029] The limiting folded edge 5 has a first end which is integrally connected to the sleeve body 1, and a second end which extends to the outside of the sleeve body 1. The limiting folded edge 5 is used to provide positioning support for the installation of the sleeve. A limiting ring groove 6 is provided on the bottom surface of the limiting folded edge 5. The limiting ring groove 6 extends along the circumference of the limiting folded edge 5, and a lubricating oil storage space is formed in the limiting ring groove 6.

[0030] In this embodiment, an oil filling hole 7 is opened on the sleeve body 1, and the first end of the oil filling hole 7 is located on the outer wall of the sleeve body 1. The operator can easily add lubricating oil from the outside of the sleeve without removing the sleeve; the other end of the oil filling hole 7 is connected to the lubrication channel 4, and the lubricating oil enters the lubrication channel 4 through the oil filling hole 7, and flows along the channel to the contact surface between the sleeve body 1 and the rotating shaft to achieve lubrication.

[0031] In this embodiment, the lubrication channel 4 is distributed in a spiral shape, which is used to provide a spiral flow path so that the lubrication oil can evenly cover the contact surface between the sleeve body 1 and the rotating shaft.

[0032] In this embodiment, the first end of the oil filling hole 7 is a countersunk structure, and an oil seal (omitted in the figure) is arranged in the countersunk structure. The oil filling hole 7 is sealed by the oil seal to avoid leakage of lubricating oil and prevent debris or dust from entering.

[0033] In this embodiment, a wear-resistant portion is provided on the inner side wall of the sleeve body 1 , the sleeve body 1 and the wear-resistant portion are integrally connected, and the wear-resistant portion is a component made of copper alloy.

[0034] In this embodiment, a buffering gap 8 is provided at the connection portion between the sleeve body 1 and the limiting fold 5, so that the sleeve has a certain deformation buffer space.

[0035] In this embodiment, a chamfer structure is provided on one end of the shaft hole 2 close to the limiting fold 5. The chamfer structure can guide the rotating shaft to smoothly enter the shaft hole 2. Especially during the installation process, the chamfer can reduce the resistance during installation and make the installation process smoother.

[0036] The practical process and principle of the utility model are as follows: During the installation process, due to the chamfered structure design on the shaft hole 2, the operator can easily introduce the rotating shaft into the shaft hole 2 to ensure the smooth installation. At the same time, the limiting folding edge 5 provides positioning support for the installation of the sleeve to ensure the accuracy of the installation position. When the sleeve is installed, the operator can add lubricating oil to the inside of the sleeve through the oil filling hole 7. The lubricating oil enters the lubrication channel 4 through the oil filling hole 7, and flows along the spiral channel to the contact surface between the sleeve body 1 and the rotating shaft to achieve a uniform lubrication effect. During the driving process of the car, the rotating shaft rotates in the sleeve. Due to the sufficient lubrication of the lubricating oil, the friction and wear are effectively reduced, and the sleeve can maintain a stable operating state. The sealing ring groove 3 and the sealing ring work together to ensure the sealing of the lubricating oil and prevent leakage.

[0037] In summary, this automobile suspension bushing has excellent sealing performance, uniform lubrication effect, convenient maintenance characteristics, good wear resistance and deformation buffering ability. During use, it can ensure the stable operation of the automobile suspension system and improve driving safety and comfort.
