Embodiment Construction

[0012] Referring to Fig. 1, the lifting lug 7 is provided with an upper pin shaft 1 and a lower pin shaft 6, the upper pin shaft 1 is set with an upper straight cylinder nylon king connecting sleeve 3, the car body 2 is set on the upper straight cylinder nylon king coupling sleeve 3, and the lower pin shaft 6 suits have lower straight cylinder nylon king connecting sleeve 4, leaf spring 5 suits on the lower straight cylinder nylon king connecting sleeve 4.

[0013] Referring to Figure 1, since the connecting sleeve is made of nylon king material, the upper straight nylon king connecting sleeve 3 and the lower straight nylon king connecting sleeve 4, the nylon king material has the characteristics of wear resistance and high temperature resistance, and it is installed on the upper pin shaft 1 And the lower pin 6 is between the upper pin 1 and the lower pin 6 and the car body 2, the leaf spring 5, because it is not a metal material in the middle of the vehicle operation, it is co...

Abstract

The present invention discloses a connecting mechanism capable of reducing the automobile noise which includes a pin, a connection element enclosing on the pin, and a connection sleeve enclosing on the pin and between the pin and the connection element, the connection sleeve is made of nylon king material. The connection sleeve is a straight cylinder nylon king connection sleeve and is formed by connecting two segments of nylon king connection sleeves, the outer side of each segment of nylon king material is extended with a nylon king guard ring. The present invention is a connecting mechanism which is simple in structure, reliable in performance, convenient in manufacturing, low in cost and can reduce the automobile noise.

Description

technical field [0001] The invention relates to a connection mechanism, in particular to a connection mechanism capable of reducing automobile noise. Background technique [0002] There is a damping steel plate between the car body and the wheel to reduce the vibration of the vehicle. The steel plate is installed on the car body through the lifting lug. The upper part is set on the lower pin shaft at the lower end of the lifting lug, and the automobile steel plate sleeve is set between the upper pin shaft and the car body, and between the leaf spring and the lower pin shaft. Because the upper pin shaft, car body, leaf spring, lower pin shaft and Automobile steel plate sleeves are all made of metal materials, and they rub and collide with each other during the operation of the vehicle, resulting in relatively loud noises. For the pin sleeves connected by the automobile steel plate and the vehicle frame and the balance bar pin sleeves on the balance bar, larger noises are als...
