Problems solved by technology

[0009] In order to overcome the above problems, the present invention provides a sub-frame welded with hollow cast aluminum and aluminum profiles to meet the target requirements for strength and rigidity of the sub-frame in a compact layout space, save weight, and improve The dynamic rigidity of the mounting point of the suspension solves the difficult problem of integral casting of the large aluminum sub-frame, and meets the MacPherson and double-wishbone suspension requirements for the layout, function and collision safety of the sub-frame. Advantages of rigidity and light weight

Abstract

The invention belongs to the technical field of passenger car components, and in particular relates to a sub-frame welded with hollow cast aluminum and aluminum profiles; it includes a left hollow cast body, a right hollow cast body, a front beam, a middle beam, a rear beam, and a left front control arm installation Bracket, left front body mounting hole support column, left rear control arm mounting bracket, left middle body mounting hole support column, left rear body mounting hole support column, right front control arm mounting bracket, right front body mounting hole support column, right rear control arm mounting Bracket, right middle body mounting hole support column, right rear body mounting hole support column, powertrain front suspension mounting bracket, powertrain left rear suspension mounting bracket and powertrain right rear suspension mounting bracket; Difficulties in integral casting of aluminum sub-frames meet the MacPherson and double-wishbone suspension requirements for sub-frame layout, function and collision safety, and also have the advantages of high strength, high rigidity, and light weight.

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...
