Abstract

The invention provides a heavy-duty automobile front lower protection part to solve the problems that it is difficult to reduce the weight of the heavy-duty automobile front lower protection part andthe energy absorption effect is poor. The heavy-duty automobile front lower protection part is characterized in that the heavy-duty automobile front lower protection part comprises a front anti-collision transverse beam, a left support, a right support, a left inclined support and a right inclined support; the left inclined support is fixedly connected between the left end of the front anti-collision transverse beam and the left support; the right inclined support is fixedly connected between the right end of the front anti-collision transverse beam and the right support; the left inclined support, the right inclined support, the left support and the right support each comprises a hollow regular section with reinforcing ribs; the whole front anti-collision transverse beam is of an arc-shaped structure, the cross section of the front anti-collision transverse beam is of a hollow unequal-thickness irregular special-shaped structure with flanges and reinforcing ribs, and the flanges are located on the inner side face of the front anti-collision transverse beam; and the wall thickness of the connection positions of the front anti-collision transverse beam, the left inclined support, the right inclined support, the left support and the right support is larger than the wall thickness of the positions.

Description

technical field [0001] The invention belongs to the technical field of automobile protection, and in particular relates to a front and lower protection of a heavy-duty automobile. Background technique [0002] The front and lower protective parts of heavy-duty vehicles are of great significance, which can effectively prevent small vehicles from getting into the bottom during a frontal collision, and reduce the degree of injury in traffic accidents. Due to the limitations of the heavy-duty vehicle chassis and the structural form of the front of the vehicle, it is difficult for heavy-duty vehicles to meet regulatory requirements under the conditions of light structure and easy installation. For this reason, it is of great significance to develop a heavy-duty vehicle front and lower protection with reliable strength, light weight and collision energy absorption characteristics, which is easy to install and easy to maintain. Contents of the invention [0003] In order to solv...
