Fifth cast beam of frame of heavy truck

Abstract

The invention provides a fifth cast beam of a frame of a heavy truck, belonging to the heavy truck. The fifth cast beam is characterized by mainly consisting of a beam body, a front push rod support and a rear push rod support, wherein the front push rod support and the rear push rod support are arranged in an inner chamber of the beam body, the beam body is shaped as a box provided with a cavity, and mainly consists of a top plate, a bottom plate, a left side plate and a right side plate which are cast into a whole, the left side plate and the right side plate are vertical panels which are arranged symmetrically, front lightening holes and rear lightening holes are formed on surfaces of the left side plate and the right side plate, the top plate is biased forwards relative to the bottom plate, the bottom plate is an symmetrically arranged butterfly plate, symmetric arc-shaped recesses are formed on a front edge and a rear edge of the top plate, turnup reinforcing rib plates are arranged at the front edge and the rear edge of the bottom plate, the front push rod support and the rear push rod support are symmetrically arranged in a rectangular space at the middle part of the beam body, and are cast into a whole, side plate mounting holes are arranged on the left side plate and the right side plate respectively, riveting through holes are respectively formed on the top plate in a bilaterally symmetrical manner, and bolt connecting holes are formed on the bottom plate respectively in a bilaterally symmetrical manner. The fifth cast beam provided by the invention has the advantages of high torsion resistance, high deformation resistance and long service life.

Description

technical field [0001] The invention belongs to a frame of a heavy truck, in particular to a fifth beam of a frame of a heavy truck. Background technique [0002] The fifth beam of the existing heavy-duty truck frame is mostly a steel stamping part. Although the overall state is stable after installation, the fifth beam is seriously twisted and deformed when the load is large, which often causes the frame and balance suspension to be damaged. The damage to the frame will reduce the service life of the frame. Contents of the invention [0003] The object of the present invention is to propose a casting fifth beam of a heavy truck frame, which is cast steel material and integrally cast, and the thrust rod support is combined to improve the overall strength, and further improve the quality of the fifth beam and the vehicle. shelf life. [0004] The object of the present invention is achieved in this way: a cast fifth beam of a heavy truck frame (hereinafter referred to as t...
