All-terrain vehicle and its frame

Abstract

The invention discloses an all-terrain vehicle and its vehicle frame. The vehicle frame comprises: an upper main beam assembly including two upper main beams; a lower main beam assembly including two lower main beams; The first connecting beam assembly, the second connecting beam assembly and the third connecting beam assembly are arranged in sequence from front to back, a part of the upper main beam assembly, a part of the lower main beam assembly, the second connecting beam assembly and the third connecting beam assembly The beam assemblies define the installation space of the electric control device and at least one is provided with the installation part of the electric control device. Therefore, by arranging five sets of connecting beam assemblies, the supporting strength of the middle part in the front-rear direction of the vehicle frame can be effectively improved, and the structural stability of the vehicle frame can be improved. Moreover, such setting can facilitate the arrangement of the electronic control device, can effectively separate the electronic control device from the exhaust device, and can prevent high-temperature exhaust gas from affecting the work of the electronic control device.

Description

technical field [0001] The invention relates to the technical field of all-terrain vehicles, in particular to an all-terrain vehicle and its vehicle frame. Background technique [0002] In related technologies, the vehicle frame of all-terrain vehicles is mostly welded and combined by four parts: front assembly, rear assembly, upper assembly and bottom assembly; To the tail, this forms a relatively long heating and high temperature zone, which brings a lot of trouble when arranging oil circuits and electrical components, especially some relatively large and temperature-sensitive electrical components. There is no way to arrange it. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a vehicle frame of an all-terrain vehicle, which has good structural reliability and can rationally arrange various devices so that the overall layo...
