AI Technical Summary

Technical Problem

The problem of motorcycle rear swingarms wearing out and eventually breaking due to the tension they experience during vehicle acceleration or deceleration.

Method used

A self-unloading motorcycle rear swingarm was designed, employing a connecting mechanism and a buffer mechanism, including a connecting beam, a blocking block, and an elastic block. The deformation of the blocking block and the bending of the elastic block absorb the force, preventing the motorcycle rear swingarm from breaking.

Benefits of technology

It effectively absorbs the force of the motorcycle's rear swingarm during acceleration or deceleration, preventing breakage. When damaged, only the vulnerable connecting beam needs to be replaced, saving materials and ensuring that the rider can continue riding to the repair shop.

Abstract

This utility model relates to the field of motorcycle parts technology, specifically disclosing a rear swingarm fork for a self-unloading motorcycle. It includes a front axle sleeve with two sets of first load beams. A crossbeam is positioned between the two sets of first load beams. Each set of first load beams has a rotatable second load beam, and the first and second load beams are not in contact. A connecting mechanism and a buffer mechanism are provided between the first load beam and the corresponding second load beam. The connecting mechanism is located outside the first and second load beams, and the buffer mechanism is located inside the first and second load beams. This invention solves the technical problem that when the vehicle accelerates or decelerates, the drive chain exerts an upward or downward pulling force on the swingarm, which can cause wear and tear on the rear swingarm of a self-unloading motorcycle, ultimately leading to breakage.
