All-terrain vehicle and rocker arm structure thereof

Abstract

The invention provides a rocker arm structure of an all-terrain vehicle. The rocker arm structure of the all-terrain vehicle comprises a frame, a rear axle, a left rear rocker arm and a right rear rocker arm, wherein the rear axle is arranged at the rear end of the frame; a left rocker arm pull rod and a right rocker arm pull rod extend from the rear axle; a left rim support and a right rim support which are connected with the left rocker arm pull rod and the right rocker arm pull rod are respectively arranged on two sides of the rear axle; the left rear rocker arm and the right rear rocker arm are respectively arranged on two sides of the frame, extend out from the front end of the frame and are connected with the rim supports; a left shock absorber mounting seat which supports a left shock absorber of the all-terrain vehicle is arranged on the top of the left rear rocker arm; and a right shock absorber mounting seat which supports a right shock absorber of the all-terrain vehicle is arranged on the top of the right rear rocker arm. The shock absorbers of the all-terrain vehicle are directly supported by the left rear rocker arm and the right rear rocker arm; and when swinging vertically, the all-terrain vehicle is supported by the left rear rocker arm and the right rear rocker arm in a swinging manner, therefore, the shock absorption stroke of the shock absorber is increased, and the shock absorption property of a rear suspension is improved. The invention further provides an all-terrain vehicle.

Description

technical field [0001] The invention relates to the technical field of all-terrain vehicles, and more specifically, relates to an all-terrain vehicle and its rocker arm structure. Background technique [0002] All-terrain vehicles are commonly known as "beach vehicles", also known as "all-terrain four-wheel off-road locomotives". The vehicles are simple and practical, have good off-road performance, and generally have no canopy in appearance. Walk freely on the terrain. Because its structure is very similar to that of a motorcycle, and many parts are common to motorcycles, some people call it a "four-wheeled motorcycle". This type of vehicle has a variety of uses and is not limited by road conditions. [0003] For existing all-terrain vehicles, the rear suspension adopts double A-arm rear rocker arms to support the rim support, and the rear rocker arms are fixed on the frame. It can rotate up and down. In order to ensure the stability of the support structure of the rear ...

AI Technical Summary

Problems solved by technology

[0003] For existing all-terrain vehicles, the rear suspension adopts double A-arm rear rocker arms to support the rim support, and the rear rocker arms are fixed on the frame. It can rotate up and down. In order to ensure the stability of the support structure of the rear rocker arm, the half shaft needs to have a large support angle and swing slippage, and the stroke of the shock absorber is limited by the structure of the rear rocker arm. The shock absorption stroke is limited, which affects Overall Rear Suspension Performance
