Driving cab frame structure with wide vision

Abstract

The invention belongs to the technical field of vehicle engineering, and particularly relates to a driving cab frame structure with wide vision. The driving cab frame structure with the wide vision comprises a rear window frame and two side window frames; each side window frame comprises a squared-shaped upper special pipe, a first lower special pipe, a rear special pipe and a front special pipe; the rear window frame comprises a second lower special pipe and a first bending plate; a protruded portion and two first glass gluing surfaces towards the outer side of the driving cab are installed on rear special pipes, upper special pipes, the first lower special pipes, the front special pipes and the second lower special pipe in a full-length mode; a second glass gluing surface, the first glass gluing surfaces of the second lower special pipe, the first glass gluing surfaces of the two rear special pipes are located on the same plane; and the first glass gluing surfaces of each rear special pipe, each upper special pipe, each first special pipe and each front special pipes are located on the same plane. The driving cab frame structure with the wide vision has the beneficial effects that the weight of the driving cab is reduced; a procedure of forming plates by butt welding and gluing of glass can be omitted; deformation is lowered; manufacturing precision is easy to ensure; special pipes are high in strength, small in cross section, good in vision effect.

Description

technical field [0001] The invention belongs to the technical field of vehicle engineering, and in particular relates to a driver's cab frame structure with a wide field of view. Background technique [0002] At present, the main bulldozer cab structure on the market, especially the rear structure of the cab, mostly adopts the main frame welded by square tubes, and then welds and bends plates on the square tubes to install glass (bonded glass), Install sealing strips, connections between square tubes and sealing structures. Due to the complex structure, more materials, and more welding of pipes and plates, the cab with this structure has cumbersome manufacturing processes, heavy structure, and serious welding deformation. The resulting cab has large dimensional errors. Manufacturing precision, the manufacturer has to invest a lot of tooling and fixtures, and increase the shaping and correction process in the subsequent production process, the cost of the cab produced in thi...

Due to the complex structure, more materials, and more welding of pipes and plates, the cab with this structure has cumbersome manufacturing processes, heavy structure, and serious welding deformation. The resulting cab has large dimensional errors. Manufacturing precision, the manufacturer has to invest a lot of tooling and fixtures, and increase the shaping and correction process in the subsequent production process, the cost of the cab produced in this way is very high; and the cab takes up a large area due to the plate, resulting in glass area Small, limited field of view, affecting the driver's operation
