Frame structure suitable for heavy electric drive special vehicle chassis

Abstract

The invention discloses a frame structure suitable for a heavy electric drive special vehicle chassis. The frame structure comprises a left longitudinal beam and a right longitudinal beam which are symmetrically arranged, a front end is connected with the left longitudinal beam and the right longitudinal beam through a front beam, and the middle of the left longitudinal beam and the middle of the right longitudinal beam are supported by a plurality of beam welding parts, a plurality of tail beam welding parts, a plurality of motor supporting seat welding parts and a plurality of steering reinforcing beam welding parts. A power unit upper supporting beam welding part and a power unit lower supporting beam welding part serve as a middle supporting beam, and support is provided for installation of a battery pack and a controller. According to the novel frame structure, all system interfaces can follow the traditional vehicle type structure, the arrangement space of the upper system interfaces is sufficient, the novel frame structure can serve as a universal frame, the frame structure is reasonable in design, novel in form and high in bearing capacity, the good cross-country performance and passing performance of a chassis can be guaranteed, and the novel frame structure is quite suitable for a novel full-electric-drive heavy special vehicle.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a frame structure suitable for the chassis of heavy-duty electric-driven special vehicles. Background technique [0002] Traditional trucks generally use a non-load-bearing frame, and the frame structure generally uses "C"-shaped longitudinal beams and channel steel to form a trapezoidal frame, while special vehicles have the characteristics of large load-bearing mass, high stability and good passability. The traditional "Z" type, "C" type and "" type longitudinal beam structure are usually adopted, and the integral beam is interspersed between the longitudinal beams, and the entire frame is formed by riveting, screwing or welding. Provides solid support for a good ride. [0003] As the development trend of the current automobile field, electric drive vehicles also have development needs for electric drive heavy-duty special vehicles. The frame composed of tradi...
