Description

Technical Field

[0001] The utility model relates to the field of automobile parts, in particular to a suspension bushing used for an automobile. Background Art

[0002] Automobile suspension is the general term for all force-transmitting connection devices between the frame and the axle. Its function is to transmit the force acting between the wheels and the frame, and to cushion the vibration generated by the vehicle to ensure that the car can run smoothly. The suspension requires an open bushing assembly for automobile suspension. The bushing is a matching part used on the outside of mechanical parts to achieve sealing, wear protection and other functions.

[0003] The existing bushings for automobile suspension have the following problems: 1. The bushing assembly is inconvenient to install, which brings inconvenience to loading and unloading; 2. The bushing is not provided with a protective component on the outside, which is easy to be damaged when hit, thereby affecting the suspension. Therefore, there is room for improvement. Utility Model Content

[0008] Preferably, the upper protective plate and the lower protective plate are located between the two collars.

[0009] The beneficial effects of adopting the above technical solution are:

[0010] 1. The sleeve ring fixes the two ends of the bushing, and then the upper bushing and the lower bushing are fixedly mounted on the outside of the suspension. The insertion of the clamping block and the clamping groove in the upper bushing and the lower bushing limits the upper bushing and the lower bushing, making the combination more stable. At the same time, this connection method facilitates the loading and unloading of the bushing in the suspension.

[0011] 2. The bushing is more durable by setting the wear-resistant layer inside the upper bushing and the lower bushing.

[0012] 3. The upper and lower protective plates cooperate with the first telescopic rod, the second telescopic rod, the first spring and the second spring to protect the upper and lower bushings, so that the bushings are not easily damaged when impacted, thereby increasing their service life.
