Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile front subframes, in particular to a novel stamping and welding front subframe. Background Art
[0002] In traditional subframes, most of the longitudinal beams are hollow, which will cause a bad collision. Due to limited materials, it cannot absorb all the energy, and the excess energy will be transferred to the body in the cab, thereby injuring the body. Secondly, when the rear point of the vehicle body is far away from the longitudinal beam, the rear part of the subframe in the traditional overlap method cannot obtain sufficient rigidity, especially when the load at the stabilizer bar position is large, there will be strength problems. Therefore, we propose a new stamping and welding front subframe to solve the above problems. Utility Model Content
[0003] The purpose of the utility model is to provide a new type of stamped and welded front subframe, in which a large number of reinforcing plates are arranged in the longitudinal beam, a total of 4 plates, which are cleverly placed in reasonable positions, which not only improves the ability of the subframe to absorb energy in a collision, but also improves the rigidity of the front point of the swing arm and the stabilizer bar. At the same time, the rear point of the vehicle body is connected to the rear point bracket of the vehicle body by the longitudinal beam and the rear cross beam, and the rigidity is improved because the stabilizer bar point obtains closer support.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a novel stamped and welded front subframe, comprising a front subframe body, which is composed of a rear crossbeam, a left longitudinal beam, a right longitudinal beam and a front crossbeam, the left and right ends of the rear crossbeam are respectively connected to the left longitudinal beam and the right longitudinal beam, the rear ends of the left longitudinal beam and the right longitudinal beam are both connected to the front crossbeam, the interiors of the left longitudinal beam and the right longitudinal beam are both provided with reinforcing plates, and the left longitudinal beam, the right longitudinal beam and the rear crossbeam enclose a rear body mounting bracket.
[0005] Preferably, the rear cross beam is arranged parallel to the front cross beam.
[0006] Preferably, the left longitudinal beam is arranged in parallel with the right longitudinal beam.
[0007] Preferably, four groups of reinforcing plates are provided inside the left longitudinal beam and the right longitudinal beam.
[0008] Preferably, the rear vehicle body mounting bracket passes through the left longitudinal beam and the right longitudinal beam.
[0009] Compared with the prior art, the utility model has the following beneficial effects: the new stamped and welded front subframe has a large number of reinforcing plates arranged in the longitudinal beam, a total of 4 plates, which are cleverly placed in reasonable positions, which not only improves the ability of the subframe to absorb energy in a collision, but also improves the rigidity of the front point of the swing arm and the stabilizer bar. At the same time, the rear point of the vehicle body is connected to the rear point bracket of the vehicle body by the longitudinal beam and the rear cross beam, which improves the rigidity of the rear part of the vehicle body as a whole, and because the stabilizer bar point obtains closer support, the rigidity becomes better;
[0010] 1. The left and right longitudinal beams use 4 sets of reinforcement plates, which can absorb collision energy through reasonable layout and improve the dynamic stiffness of the front point of the swing arm and the stabilizer bar;
[0011] 2. The rear point overlap method of the vehicle body is novel. The left longitudinal beam, right longitudinal beam and rear cross beam wrap the rear body mounting bracket, which increases the overall rigidity of the rear part of the vehicle body, supports the mounting point of the stabilizer bar, and reduces strength damage.
