Abstract

The invention belongs to the technical field of passenger car parts, and particularly relates to an auxiliary frame obtained through welding hollow cast aluminum and aluminum profiles. The auxiliary frame comprises a left hollow cast body, a right hollow cast body, a front cross beam, a middle cross beam, a rear cross beam, a left front control arm installation support, a left front car body installation hole supporting column, a left rear control arm installation support, a left middle car body installation hole supporting column, a left rear car body installation hole supporting column, a right front control arm installation support, a right front car body installation hole supporting column, a right rear control arm installation support, a right middle car body installation hole supporting column, a right rear car body installation hole supporting column, a front suspension installation support of a power assembly, a left rear suspension installation support of the power assembly and a right rear suspension installation support of the power assembly. The problem that the inblock cast of the large-scale aluminum auxiliary frame is difficult is solved, the arrangement, function and crashworthiness requirements of Macpherson double wishbone suspension on the auxiliary frame are met, and the advantages of high strength, high rigidity, light weight and the like are achieved.

Description

technical field [0001] The invention belongs to the technical field of passenger car parts, and in particular relates to a sub-frame welded with hollow cast aluminum and aluminum profiles. Background technique [0002] As an important part of the suspension, the subframe is responsible for connecting the body, powertrain, steering gear, stabilizer bar, control arm and other important parts of the car. It has been widely used in the field of passenger cars. [0003] The following types of subframes are used more at this stage: [0004] 1. The sub-frame of stamping and welding of steel plate is the most widely used and cheap in cost, but its weight is relatively large, which is not conducive to the lightweight of the whole vehicle. [0005] 2. The sub-frame welded by steel pipes, this type of sub-frame is currently used on small electric vehicles, and its carrying capacity is low. [0006] 3. Integral cast aluminum sub-frame, the current size of this type of sub-frame is sma...
