Problems solved by technology

[0003] At present, the installation of the front suspension control arm and the front longitudinal beam is usually directly welded or bolted with a relatively large and complicated installation structure, so that the connection between the two is relatively rigid.
Therefore, when the car collides, the front suspension control arm will affect the crushing space of the front longitudinal beam, thereby affecting the safety performance of the car
[0004] In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: the existing front suspension control arm installation structure is high in strength, complex in structure, and occupies a lot of crushable space for the longitudinal beam, which greatly affects the front longitudinal beam. The crushing and deformation of the beam during the collision will affect the absorption of collision energy by the body during the collision, which is not conducive to improving safety performance

Embodiment 1

[0021] This embodiment provides a mounting piece for a front cantilever control arm, see figure 1 , figure 2 with image 3 The mounting member 1 is used to mount the front cantilever control arm 2 on the front longitudinal beam 3. The mounting member 1 includes a concave body 101 and a mounting edge 102. The center of the concave surface of the concave body 101 is provided with a bolt hole 103, and the mounting edge 102 can easily fix the mounting member 1 to the front longitudinal beam 3. Preferably, the concave body 101 has a hemispherical structure, and the mounting edge 102 and the concave body 101 are integral members formed integrally. As other embodiments, the concave body 101 may also have a bowl-shaped structure. In this embodiment, the mounting member 1 is fixed to the front longitudinal beam 3 by welding, and preferably a four-point welding method. The four welding points are distributed symmetrically on the front longitudinal beam. The area, that is, the four weld...

Embodiment 2

[0025] An embodiment of the present invention provides a car, which has the mounting part of the front cantilever control arm provided in the first embodiment. The car absorbs the energy of the collision energy very significantly in the event of an accidental collision, thereby greatly improving the installation performance of the car and greatly reducing the risk of drivers and passengers.

[0026] The sequence numbers of the foregoing embodiments of the present invention are only for description, and do not represent the superiority of the embodiments.

Abstract

The invention discloses a mounting part of a front suspension control arm, and belongs to the automobile body structure field. The mounting part is used for mounting a front suspension control arm (2) onto a front longitudinal beam (3), and comprises a concave body (101) and a mounting side (102), a threaded hole (103) is opened in the concave center of the concave body (101), the mounting side (102) is mounted on the lower surface of the front longitudinal beam (3) by welding, riveting or bolt connecting, and the front suspension control arm (2) is mounted on the concave body (101) through a bolt. The invention further discloses an automobile with the mounting part. According to the mounting part of the front suspension control arm and the automobile with the same, the front suspension control arm is mounted on the front longitudinal beam through the mounting part, the mounting part is simple in structure, and convenient to machine by being connected with the front longitudinal beam in a point welding mode; the bolt is arranged on the concave body of the mounting part which is connected with the front suspension control arm through the bolt, so that mounting and dismounting of the front suspension control arm are more convenient, simple and rapid.

Description

Technical field [0001] The invention relates to the field of automobile body structure, in particular to a mounting piece of a front cantilever control arm, which mounts the front cantilever control arm of an automobile on a front longitudinal beam. The invention also relates to an automobile having the above-mentioned mounting member. Background technique [0002] With the rapid development of the automobile industry, the safety performance requirements of automobiles are becoming higher and higher. When an accident occurs in a car, the car body is required to have a good energy absorption effect to maximize the living space of the driver and passengers. Reducing the deformation of the cab is the most basic requirement. The front longitudinal beam is a beam located on both sides of the front part of the car body and under the shock-absorbing tower of the car. It is the main component for building the engine room and load-bearing. It bears the longitudinal force of the car and t...
