All-terrain vehicle and rear vehicle frame thereof

Abstract

The invention discloses a rear vehicle frame of an all-terrain vehicle. The rear vehicle frame comprises bent plates, tubular beams and steel channels. The whole bent plates are bent along short edges, and long edges are linear. The two bent plates are opposite and are welded to the two ends of each of the multiple tubular beams. The multiple tubular beams are distributed along the upper long edges and the lower long edges of the bent plates. The two steel channels are located at the two ends of each of the lower long edges of the bent plates. The two ends of each of the two steel channels are welded to the two bent plates. End plates are arranged at the front ends of the two bent plates. A connecting plate is welded to the front end plate through a frame structure. First installation holes are formed in the positions, located at the two ends of each of the upper long edges of the bent plates, of the tubular beams, and second installation holes are formed in the positions, located at the two ends of each of the lower long edges of the bent plates, of the steel channels. The interior of each tubular beam is of a hollow structure, and meanwhile the mass of the bent plates is relatively small. By the adoption of the above structure, the function of the rear vehicle frame is achieved, the strength of the rear vehicle frame is guaranteed as well, and the weight of the rear vehicle frame is reduced. The bearing capacity of the all-terrain vehicle can be guaranteed, the weight is reduced, and the use range of the all-terrain vehicle is broadened. The invention further discloses the all-terrain vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a rear frame of an all-terrain vehicle. In addition, the present invention also relates to an all-terrain vehicle with the above-mentioned rear frame. Background technique [0002] All-terrain vehicles can adapt to complex terrains, overcome special environments such as harsh terrains, craters, and dirt ridges that other vehicles are difficult to pass through, and can also operate smoothly in snowy fields, swamps, tidal flats, lakes and other terrain environments. [0003] All-terrain vehicles are usually articulated double-body structures, including front vehicles, hinged devices and rear vehicles, which are connected by hinged devices; rear vehicles include running gear, rear frames, main fuel tanks and rear compartments , the front end of the rear frame is connected with the hinged device, the running gear is installed below, the rear compartment is installed abov...

AI Technical Summary

Problems solved by technology

Usually, the rear frame is welded by section steel. Although the load-bearing capacity of the rear frame can be guaranteed, the quality of the rear frame is relatively heavy, which makes the quality of the all-terrain vehicle heavier, so that the all-terrain vehicle cannot be limited in weight. Exercising on road conditions limits the scope of application of all-terrain vehicles
