Reinforced type scrambling motorcycle rear fork

Abstract

The invention discloses a reinforced type scrambling motorcycle rear fork. The reinforced type scrambling motorcycle rear fork comprises two symmetrically arranged fork main pipes and a connecting plate enabling the two fork main pipes to be connected. The fork main pipes are formed by welding two seamless pipes, and the two seamless pipes are in a quadrangle after being bent and welded. Reinforcing plates matched with the fork main pipes in shape are welded to the inner sides of the two fork main pipes. The two seamless pipes are bent and combined into the quadrangle and then are welded to form the fork main pipes of the rear fork, so the structural stability of the rear fork is greatly improved, force borne by all directions is better decomposed, so the rear fork can better adapt to the use environment of a scrambling motorcycle; the reinforcing plates welded to the inner sides of the two fork main pipes further reinforce the structural strength of the rear fork, so it can be guaranteed that the fork main pipes will not deform after being used for a long time, and the rear fork is firm and durable.

Description

technical field [0001] The invention relates to a reinforced rear balancer for off-road motorcycles. Background technique [0002] The motorcycle rear chainstay is one of the important parts of the motorcycle, it is mainly composed of the left and right chainstay main pipes and the connecting plate connecting the left and right chainstay pipes. The rear chainstay is located in the middle and lower part of the motorcycle, generally in the shape of an "H", and is installed between the frame and the axle of the motorcycle to play a supporting and connecting role. The existing motorcycle rear fork is generally directly designed as a single-tube type fork supervisor due to cost reasons. This design has two shortcomings: 1. The pressure on the single tube is uneven and cannot be well decomposed from the motorcycle. 2. The welding stress concentration of the main tube of the single-tube flat fork has a certain impact on the dimensional accuracy of the rear flat fork and the servic...

The existing motorcycle rear fork is generally directly designed as a single-tube type fork supervisor due to cost reasons. This design has two shortcomings: 1. The pressure on the single tube is uneven and cannot be well decomposed from the motorcycle. The impact of all aspects caused by the movement of the car; 2. The welding stress concentration of the main tube of the single-tube flat fork has a certain impact on the dimensional accuracy of the rear flat fork and the service life of the rear flat fork

The rear balance fork of this structure is applied to off-road motorcycles, and the use state is even worse. Therefore, the existing rear balance fork needs to be improved
