Embodiment Construction

[0042] Refer to figure 1 , figure 2 , An off-road vehicle composite material trailing arm, the trailing arm 6 includes a support frame layer; the support frame layer is covered with an adhesive film layer; the outer side of the adhesive film layer is covered with a carbon fiber material layer 2.

[0043] The carbon fiber material layer 2 adopts a 45-degree alternately layered interwoven carbon fiber cloth, and the number of layers of the carbon fiber material layer 2 is 6-20.

[0044] The connecting portion of the trailing arm 6 and the wheel assembly 8, the connecting portion of the shock absorber lower ear piece 9 of the shock absorber 5, the connecting portion of the trailing arm front ear piece and the upper and lower corners of the trailing arm are made of aluminum material 4 is used as the core material; the remaining part uses the balsa material 1 as the core material to build the supporting frame of the trailing arm; the aluminum material 4 and the balsa material 1 are conn...

Abstract

The invention belongs to the technical field of an automobile and particularly relates to an off-road vehicle composite trailing arm and a manufacturing method thereof. The trailing arm includes a support frame layer, an adhesive film layer and a carbon fiber material layer are laid on the outer side of the supporting frame layer, and a supporting frame is composed of a balsa wood material, an aluminum material and super glue. The trailing arm is advantaged in that the mass of the trailing arm is effectively reduced while good mechanical properties are guaranteed, and the trailing arm has goodimpact resistance, is not prone to breakage and breakage, still has a high safety coefficient under severe driving conditions and guarantees safety of a driver, a new structural connection form for the structure is provided, the aluminum material is partially pre-buried in the carbon fiber material layer, a part of the aluminum material is externally processed into the mounting hole, so a weldingerror of a traditional trailing arm structure is eliminated.

Description

Technical field [0001] The invention belongs to the technical field of automobiles, and specifically relates to an off-road vehicle composite material trailing arm and a manufacturing method thereof. Background technique [0002] Nowadays, people have higher and higher requirements for the performance of off-road vehicles, and the unsprung mass of off-road vehicles is an important measure of the performance of off-road vehicles. Among them, the weight reduction of the trailing arm has become the goal of many off-road vehicles. At present, off-road vehicles generally use tailor-welded steel pipe and steel stamped towing arms, which are too large in quality and low in strength; in addition, these two types of trailing arms require different degrees of welding technology, resulting in different degrees of welding errors . Summary of the invention [0003] The invention provides an off-road vehicle composite material trailing arm and a manufacturing method thereof. The trailing arm a...
