Frame of multifunctional special car

Abstract

The invention relates to a frame of a multifunctional special car, belonging to the field of the car. The frame of the multifunctional special car is provided with a front upper frame and is characterized in that the front upper frame and lower frame front small vertical beams are connected through a front small frame; the left and right lower frame front small vertical beams are welded with left and right lower frame vertical beams, and left and right front vertical columns through front first circular tube type cross beams; the upper ends of the left and right front vertical columns are welded at the two ends of the front upper frame and upper cross beams of the front vertical columns are connected with the left and right front vertical columns; the upper cross beams of the front vertical columns are connected with the lower frame front small vertical beams through a connecting frame; lower frame second circular tube type cross beams are welded with the left and right lower frame front small vertical beams and the left and right lower frame vertical beams; the left and right lower frame vertical beams are welded together through front and back third circular tube type cross beams; the lower frame vertical beams are connected with the front ends of upper frame vertical beams through upper and lower frame connecting angle steel; an upper frame rear cross beam is welded between the back ends of the two upper frame vertical beams; and the two ends of lower frame rear circular tube cross beams pass through the left and right lower frame vertical frames and are welded with left and right rear plate spring front lifting lugs.

Description

technical field [0001] The invention relates to the field of vehicles, in detail it is a multifunctional special vehicle frame suitable for farming, animal husbandry and forestry operations. Background technique [0002] As we all know, multi-purpose special vehicles have powerful functions and complex structures, and numerous operating function modules need to be connected to the vehicle conveniently and efficiently. [0003] At present, the traditional trapezoidal frame is mostly used, which is composed of two groove-shaped longitudinal beams parallel to each other with openings facing inward, and some punched groove-shaped longitudinal beams and some punched open groove-shaped beams. Its advantages are simple structure, high bending rigidity, and easy installation of body, compartment and other assembly parts. Its disadvantages are: the driver's seat and the bottom plate are high, and it is inconvenient for the driver to get up and down; the structure is simple, but it ...

AI Technical Summary

Problems solved by technology

Its disadvantages are: the driver's seat and the bottom plate are high, and it is inconvenient for the driver to get up and down; the structure is simple, but it is difficult to install the interface device of the operation module, and the torsional rigidity is small

[0004] Because the traditional trapezoidal frame is used for multi-purpose vehicles, there are high heights between the driver's seat and the floor, inconvenience for the driver to get up and down, difficulty in installing complex operation module interface devices and poor torsional rigidity, etc., which cannot meet the needs of modern multi-purpose special vehicles. frame requirements
