Fender bracket based on cast aluminum process

Abstract

The present invention provides a fender bracket processed using a cast aluminum process, relating to the technical field of automotive parts, comprising: a vehicle frame body; a mounting and connecting assembly disposed on a side of the vehicle frame body; a fender bracket body having a V-shaped structure connected to the side of the vehicle frame body via the mounting and connecting assembly; and a fender mounting plate fastened to the front side of the fender bracket body. By adopting semi-solid cast aluminum and a structural design to replace the conventional cast steel structure, the machining allowance is small and the machining efficiency is high, thereby achieving lightweight automotive parts. This solves the problem that conventional fender brackets use cast steel structures, which are bulky and heavy, and that cast steel parts have large casting allowances, resulting in excess strength, large machining allowances, low machining efficiency, and part weight often exceeding the designed weight, making it difficult to meet automotive lightweighting requirements.
