a frame

Abstract

The invention provides a vehicle frame which comprises a reinforcing beam, a first steering window, a second steering window, a steering mechanism and a steering support, wherein one end of the reinforcing beam is connected with a left longitudinal beam, the other end of the reinforcing beam is connected with a right longitudinal beam, the first steering window is arranged on the left longitudinal beam, and the second steering window is arranged on the right longitudinal beam. One end of the steering mechanism is arranged on the first steering window, the other end of the steering mechanism is arranged on the second steering window. The steering support is arranged on the upper portion of one end of the reinforcing beam. Through the arrangement of a steering hydraulic cylinder on the steering support, the steering hydraulic cylinder is connected with the steering mechanism, the stress of the first steering window and the second steering window is changed, and the cracking of the first steering window and the second steering window is avoided. Therefore, the reinforcing beam structure is added to the vehicle frame, so that the stress of the positions of the steering windows is changed, the problem of cracking of the positions of the steering windows is solved fundamentally, and the overall performance of the vehicle frame is improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle engineering, and in particular relates to a vehicle frame. Background technique [0002] In the field of vehicle engineering technology, the function of the frame is to support and connect the various assemblies of the automobile, so that each assembly maintains a relatively correct position, and bears various loads inside and outside the automobile. Therefore, the performance of the frame is more and more important. [0003] At present, the frame form of the super-heavy-duty off-road vehicle chassis adopting oil-gas suspension adopts the ordinary "Z"-shaped longitudinal beam upper plane and welded groove-shaped sub-beam structure. Large features, but this structure has a large amount of welding and large welding deformation, which affects the performance of the frame. In addition, the steering support at the steering window of the frame is subject to a large force, and cracking is prone to occu...
