Abstract

The present disclosure discloses an all-terrain vehicle including a frame; a trailing arm, an upper tie rod and a lower tie rod. A front end of the trailing arm is connected to the frame. An inner end of the upper tie rod is connected to the frame and an outer end of the upper tie rod is mounted at a rear end of the trailing arm. An inner end of the lower tie rod is connected to the frame and an outer end of the upper tie rod is mounted at the rear end of the trailing arm. The lower tie rod is located below the upper tie rod. An included angle between the upper tie rod and the lower tie rod being a, and a satisfies a relationship: 0°<a<5°.
