Dump truck frame with alien-shaped longitudinal beams and sub-frame function

Abstract

The invention provides a dump truck frame with alien-shaped longitudinal beams and a sub-frame function, wherein the front section of the left longitudinal beam of the frame has an L-shaped cross section, the rear section has a Z-shaped cross section, and a rectangular notch is cut in the rear upper part; the cross section of the L-shaped front section has a small height and a small size, the cross section of the Z-shaped rear section has a large height and a large size, and a transition section is arranged in the middle of the left longitudinal beam; and the right longitudinal beam and the left longitudinal beam are symmetrical. The dump truck frame with the alien-shaped longitudinal beams and the sub-frame function can give play to functions of a common truck frame and a dump truck sub-frame, so that no sub-frame is needed when a dump truck with the structure is used, consumption of materials can be reduced, and whole-truck curb weight can be reduced. In this way, production cost can be reduced, and economical efficiency of use is greatly improved. In addition, components such as a hydraulic oil cylinder support horizontal beam used for container lifting and an oil tank bearing horizontal beam can be connected and installed more conveniently. The dump truck frame with alien-shaped longitudinal beams and the sub-frame function can be widely applied in the damp trucks.

Description

technical field [0001] The invention relates to the technical field of dump truck manufacturing, in particular to a special-shaped longitudinal beam dump truck frame with the function of a sub-frame. Background technique [0002] The current dump truck generally adopts the subframe, which is used to install the cargo box lifting cylinder, the cargo box turning shaft support and the longitudinal beam supporting the cargo box, and the subframe is required to have sufficient strength and rigidity. Therefore, more materials with a certain quality must be used to manufacture the subframe, which has a higher production cost, and because it increases the curb weight of the vehicle, it is not conducive to the economy of use. [0003] Although there is a dump truck frame with the function of a sub-frame, the left and right longitudinal beams of the frame still adopt the groove structure of the traditional truck longitudinal beams, and the front part of the frame is installed with dri...

AI Technical Summary

Problems solved by technology

Although it can better meet the requirements of installing driving, engine and other components, due to the small overall width of the upper wing surface of the frame supporting the cargo box section at the rear, the distance between the longitudinal beams of the two bottom plates of the cargo box matching it is small, and the cargo The cantilever part of each floor beam of the box is large in size and easy to be damaged

In addition, the riveting installation of cargo box lifting hydraulic cylinder, hydraulic oil tank support beam and other components is also difficult
