Description

Girder with heavy truck variable section and drop structure

Technical Field

The utility model relates to the field of automobile part manufacturing, in particular to a girder with a heavy truck variable section and fall structure.

Background

The girder is a main bearing part of a truck, almost bears the whole weight of cargoes, the quality of the girder influences the service life and the running safety of the whole truck, and the automobile girder is manufactured by adopting a stamping forming process generally, and the deformation mode is mainly bending, so that the girder plate has high requirements on formability, namely, the steel plate of the automobile girder has good comprehensive performance, enough toughness and good fatigue resistance and cold formability. With the development of the automobile industry, a high-strength steel plate with high strength, high strength and formability, which is reduced in weight and improved in safety, is a main body of automobile plate in the requirements and development directions.

The existing heavy truck girder has various varieties, belongs to straight-through or welded structures, has poor matching performance with parts such as a cab, an engine, an upper stirring tank body and the like, and has complex manufacturing process, low whole strength of the girder and high processing cost.

Disclosure of Invention

The utility model aims to provide a girder with a heavy truck variable section and drop structure, which can improve the matching property of a frame girder and parts such as a cab, an engine, an upper stirring tank body and the like on the premise of ensuring the strength requirement of the parts.

In order to solve the technical problems, the technical scheme of the utility model is as follows:

girder of heavy truck variable section and fall structure, girder body includes left and right longeron, its characterized in that: the left longitudinal beam and the right longitudinal beam are composed of an outer beam and an inner beam, the inner side of the inner beam is provided with a reinforcing plate, the height of the outer beam is lower than that of the inner beam, the front end of the inner beam is obliquely connected with the outer beam, and the left longitudinal beam and the right longitudinal beam are assembled to form an overall layout with low front and high rear and wide front and narrow rear.

The improvement of the technical scheme is as follows: the outer beam, the inner beam and the inner reinforcing plate are integrally formed through laser cutting.

Further improvement of the technical scheme is as follows: the width of the front end abdomen of the left longitudinal beam and the right longitudinal beam is 300mm, and the width of the rear end abdomen is 450mm.

The beneficial effects are that:

compared with the constant-section girder, the girder with the variable section structure saves materials, lightens the weight of the girder and realizes light weight on the premise of ensuring the integral strength. The outer beam and the inner beam are formed by adopting a whole plate mold, so that the efficiency is improved while the process is simplified, the mass rapid production is convenient, the part strength is high, the bearing requirements of the heavy pumping truck are met, and the satisfaction degree of customers is improved.

The girder with the heavy truck variable section and fall structure has the advantages that the left and right longitudinal girders are assembled in the frame assembly to form the whole layout with low front and high rear, wide front and narrow rear. The front end web width of the longitudinal beam is 300mm, the rear end web width of the longitudinal beam is 450mm, the front part of the frame assembly is opened by 940mm, the rear part of the frame assembly is opened by 860mm, perfect matching with the existing main stream cab is realized, a high-power engine has enough installation space, a stirring tank has a stronger bearing body, and the maneuvering flexibility and the firmness and the durability of the whole vehicle are obviously enhanced.
