Abstract

The invention relates to an electric automobile subframe. The electric automobile subframe includes a main beam upper sheet (10), a main beam lower sheet (20), a front cross beam upper sheet (30) and a front cross beam lower sheet (40); the front cross beam upper sheet (30) and the front cross beam lower sheet (40) are of --shaped frame structures; the front cross beam upper sheet (30) and the front cross beam lower sheet (40) are welded into a front cross beam; the main beam upper sheet (10) and the main beam lower sheet (20) are of U-shaped frame structures, and the main beam upper sheet (10) and the main beam lower sheet (20) are welded into a main beam; a left control arm installation support (50) and a right control arm installation support (60) are welded to the left side and the right side of the main beam respectively; and the front cross beam and the main beam are welded into a sealed frame structure, and automobile body installation lining casing tubes (70) are welded to four corners of the sealed frame structure. The electric automobile subframe has a small number of stamping parts under the premise of meeting a design demand, can reduce the stamping and welding processes, can reduce the cost, and can improve the production efficiency.

Description

[0001] [technical field] [0002] The invention relates to the technical field of auto parts, in particular to an electric vehicle auxiliary frame. [0003] [Background technique] [0004] With the energy-saving and emission-reduction requirements of vehicles in modern society, there are more and more electric vehicles. The motor assembly of electric vehicles usually needs to be placed on the sub-frame. In addition to carrying the motor assembly, the sub-frame also needs to install steering gear and control arms. , stabilizer bar and other parts, the subframe needs to have sufficient strength and rigidity to carry the above parts. At present, the existing frame-type sub-frame is often designed with two front and rear beams, upper and lower pieces, and two left and right longitudinal beams, with a total of eight stamping parts welded together. This design has many stamping parts, many welding processes, and high cost. The disadvantages of high production efficiency and low prod...
