Front auxiliary frame aluminum alloy mounting support and vehicle

Abstract

The invention discloses a front auxiliary frame aluminum alloy mounting support. The front auxiliary frame aluminum alloy mounting support is arranged between a front auxiliary frame and a cabin boundary beam, and comprises an aluminum alloy support body, and a connecting plate extending upwards is arranged on the edge of the upper end of the support body. The side face, opposite to the connectingplate, of the support body is fixedly connected with a reinforced plate, and the upper portion of the connecting plate and the upper portion of the reinforced plate are fixedly connected with the twoopposite side faces of the cabin boundary beam correspondingly. A vertically through threaded through hole is formed in the support body, and the threaded through hole and a second mounting hole in the cabin boundary beam are coaxially formed. The front auxiliary frame aluminum alloy mounting support can be low in weight, and the connecting problem that an existing mounting support of a steel structure and an aluminum alloy cabin boundary beam must be rivetted is solved, so that the rigidity and strength of an auxiliary frame mounting point meet requirements. The invention further discloses avehicle. The vehicle comprises the front auxiliary frame and the cabin boundary beam. The front auxiliary frame is fixedly connected with the cabin boundary beam through the aluminum alloy mounting support.

Description

technical field [0001] The invention relates to the technical field of automobile bodies, in particular to an aluminum alloy mounting bracket for a front sub-frame and a vehicle. Background technique [0002] Lightweight technology is an important technical means to achieve energy saving and emission reduction of automobiles. For this reason, various car companies have begun to design and develop all-aluminum or steel-aluminum hybrid bodies. The side beams of the body cabin are made of aluminum alloy profiles to achieve simple manufacturing and good collision energy absorption. sex. [0003] The structural performance requirements of the front mounting point of the front subframe on the side beams of the engine room are relatively high. Traditional models use steel structural parts and steel side beams to be connected by welding. see figure 1 , as shown in the structure of the installation point of the existing front sub-frame, when the material of the engine room side bea...
