Bumper installation structure assembly of motorbike back suspension

Abstract

The invention discloses a bumper installation structure assembly of a motorbike back suspension, comprising a bumper upper connector, a hinging pin shaft and a U-shaped structure connecting frame fixedly connected with a motorbike frame. The dumper upper connector is embedded between two support lugs of the U-shaped structure connecting frame and is articulated with the U-shaped structure connecting frame via the hinging pin shaft, the hinging pin shaft passes through a hinging hole of the dumper upper connector via a shock-absorbing bushing of a coating, the hinging pin shaft is provided with a shaft shoulder abutted against one axial end face of the shock-absorbing bushing, and the hinging pin shaft extends out the other axial end face of the shock-absorbing bushing and the support lugs of corresponding sides of the U-shaped structure connecting frame and is axially fastened. After the bumper installation structure assembly is installed, the shock-absorbing bushing is compressed by the shaft shoulder end face, thus the assembly gap of the shock-absorbing bushing along the hinging pin shaft is efficiently eliminated, the assembly gap is made to become an adjustable factor and the axial movement of the bumper along the hinging pin shaft when in use is avoided so as to eliminate the abnormal sound in running process of the motorbike and the leftward and rightward deflection of a back wheel and to ensure the security of the whole motorbike operation.

Description

technical field [0001] The invention relates to a motorcycle component, in particular to a motorcycle rear suspension shock absorber installation structure assembly. Background technique [0002] Motorcycles are widely used due to their lightness, flexibility, fast driving and strong road adaptability. Because motorcycles are lighter and travel faster than ordinary motor vehicles, and they are often driven on country roads, they will generate greater vibration due to road conditions. In order to alleviate and attenuate the impact and vibration of the motorcycle due to the unevenness of the road during driving, ensure the smoothness and comfort of driving, and help improve the service life of the motorcycle and the stability of the operation, the motorcycle is equipped with front and rear shock absorbers. Because the load of the motorcycle is generally at the rear, the rear shock absorber bears relatively large gravity, and at the same time, it will generate a large impact f...

AI Technical Summary

Problems solved by technology

Due to the uncontrollable deformation moment of the two lugs of the U-shaped connecting parts during assembly, it cannot be monitored during assembly; if the gap is not eliminated during assembly, the rear shock absorber will move axially in the loading hole, causing the driver to Abnormal noises are likely to occur during the process, and the left and right deflection of the rear wheels will affect the safety of the entire vehicle. If the installation is too prone to eliminate the gap in order to solve the above problems, the barrel shock absorber will be damaged during the driving of the motorcycle. When the shock absorber is in use, it forms a lateral force or torque, which causes partial wear on the shock absorber and has an adverse effect on its service life
