Abstract

The invention discloses an auxiliary frame. The auxiliary frame comprises a front cross beam, a first longitudinal beam, a rear cross beam and a second longitudinal beam which are connected in sequence, and the front cross beam, the first longitudinal beam, the rear cross beam and the second longitudinal beam are connected to form a rectangular frame structure; and the connecting face, connected with the first longitudinal beam and the second longitudinal beam, of the rear cross beam is an inclined face, and the end, connected with the front cross beam, of the first longitudinal beam and the end, connected with the front cross beam, of the second longitudinal beam are provided with notch grooves for buckling the front cross beam. According to the invention, the types of materials requiredfor producing the auxiliary frame are reduced, the mold opening cost is saved, and meanwhile, the welding process requirement is reduced.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a sub-frame. Background technique [0002] In electric vehicles, the sub-frame is an important component of the vehicle chassis. As the carrier of key components such as front and rear suspensions, it plays an important role in the safety, handling and NVH performance of the vehicle. The sub-frame is the frame that supports the suspension of the front and rear axles. The suspension is connected to the body through the sub-frame. The key point of the design is to realize the lap connection of the frame to the surrounding structures through the design of the frame structure, including the swing arm, Guiding mechanisms such as tie rods and trailing arms; supporting structures such as suspension brackets; connecting structures such as car bodies, etc. In addition, the modal and stiffness requirements of the subframe must be met. Therefore, in the current automobile research and dev...
