Problems solved by technology

Since the frame and sub-frame are manufactured separately, the advantages of the integrated structure of the two are not fully utilized. To ensure sufficient strength and rigidity, more materials with a certain quality must be used to manufacture the frame and sub-frame, so that It has high production cost, and because it increases the curb weight of the vehicle, it is not conducive to the economy of use

Embodiment Construction

[0021] A detailed description will be given below in conjunction with the accompanying drawings.

[0022] Such as Figure 1~5 Shown, the parts that need to be installed on the vehicle frame---the rear balance suspension support 17 represents with double dot dash line, does transparent processing. In the four-axle heavy-duty dump truck frame and sub-frame of the integrated structure provided by the present invention, the left longitudinal beam 1 of the vehicle frame is pressed into a groove shape with a special girder steel plate, and the outer sides of the front section and the rear section of the left longitudinal beam 1 of the vehicle frame are Not in one plane, that is, the total width of the front section frame is greater than that of the rear section, so as to ensure the installation needs of engines with larger power and size. Vehicle frame right longitudinal beam 28 is also pressed and formed with special-purpose beam steel plate, and vehicle frame left longitudinal be...

Abstract

A heavy-duty four-axle dump truck frame combined structure in an integrated structure comprises a frame and an auxiliary frame. A frame left longitudinal beam is made of beam steel plates in a channel form; the outer side of a front segment of the frame left longitudinal beam and the outer side of a rear segment thereof are in different planes; a frame right longitudinal beam is also made of beam steel plates by pressing and is symmetric to the frame left longitudinal beam. By means of the heavy-duty four-axle dump truck frame combined structure in an integrated structure, not only normal motor truck frame function can be realized, but also dump truck auxiliary frame function can be realized; the frame and the auxiliary frame are integrated into one structure so that less material is used on the premise that adequate strength and stiffness are guaranteed and therefore, the quality of the whole truck is reduced and production cost is reduced; the heavy-duty four-axle dump truck frame combined structure in an integrated structure can be widely applied in heavy-duty four-axle dump trucks due to its economical efficiency.

Description

technical field [0001] The invention relates to the technical field of dump truck manufacturing, in particular to an integrated four-axle heavy dump truck frame assembly structure. Background technique [0002] Present dump truck is generally all provided with auxiliary frame on vehicle frame, is used for installing cargo box lifting oil cylinder, cargo box overturning shaft support and the longitudinal beam of supporting cargo box. Since the frame and sub-frame are manufactured separately, the advantages of the integrated structure of the two are not fully utilized. To ensure sufficient strength and rigidity, more materials with a certain quality must be used to manufacture the frame and sub-frame, so that It has a higher production cost, and because it increases the curb weight of the vehicle, it is not conducive to the economy of use. Especially for the four-axle heavy-duty dump truck, the above-mentioned problems will be more prominent. Contents of the invention [0...
