Bearing type military off-road vehicle rear wheel cover assembly and welding method thereof

Abstract

The invention discloses a bearing type military off-road vehicle rear wheel cover assembly and a welding method thereof. The rear wheel cover assembly comprises a rear wheel cover outer plate, a chassis suspension system mounting mechanism welded on the rear wheel cover outer plate, a chassis suspension system wheel jump limiting mechanism welded on the chassis suspension system mounting mechanism and the rear wheel cover outer plate, and an accessory mounting mechanism which is welded on the rear wheel cover outer plate and is used for accessories such as an auxiliary fuel tank, a back door pedal and a rear traction member; the rear wheel cover outer plate is formed by welding a high-strength bulletproof steel plate MAG, the front face and the back face of a weld joint are welded in a gas shielded welding mode, so that it is guaranteed that the lap joint of the steel plate is completely welded, and then the strength of the rear wheel cover outer plate is guaranteed. According to structural design and selected materials, impact of certain explosives at the bottom of the vehicle can be resisted, safety of members and goods in the vehicle can be effectively protected, the structure is novel and ingenious, the manufacturing process is reasonable, and the strength can meet the functional requirements of bearing, bulletproof and impact resistance of the military off-road vehicle.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and more specifically relates to a load-bearing military off-road vehicle rear wheel cover assembly and a welding method thereof. Background technique [0002] The main function of the car body is to protect the driver and form a good aerodynamic environment. A good body can not only bring better performance, but also reflect the personality of the owner. In terms of form, the car body structure is mainly divided into two types: non-load-bearing and load-bearing. A car with a non-load-bearing body has a rigid frame, also known as a chassis frame. The body body is suspended on the vehicle frame and connected by elastic elements. The car with load-bearing body has no rigid frame, but the front, side, rear, floor and other parts are strengthened. The body and the underframe together form the rigid space structure of the body. In addition to its inherent carrying function, this load-bearing bo...

AI Technical Summary

Problems solved by technology

At present, the floor structure of passenger cars and commercial vehicles such as load-carrying cars and pickups is relatively simple. The rear floor structure is composed of a rear floor panel and a number of floor reinforcement beams. There are no mid-floor, wheel housing and other structures. The materials are generally galvanized steel and High-strength steel for stamping, with a plate thickness of 0.7-1.5mm, is formed by resistance spot welding, and can only carry people and objects in general. The floor does not have a strong load-bearing capacity and lightning-proof and bullet-proof level in terms of structure, strength and materials. It cannot meet the functional requirements of military off-road vehicles for bearing, bulletproof and impact resistance
