Problems solved by technology

However, the front subframe in this patent has an upwardly extending front vehicle body mounting frame. Compared with the front subframe directly connected with the vehicle body, this connection method reduces the rigid connection between the vehicle body and the front subframe. , at the same time, the existence of the mounting frame also aggravates the vibration problem of the front sub-frame

Embodiment 1

[0024] Example 1, such as Figure 1 to Figure 8 As shown, the front subframe assembly of the automobile includes the upper plate 1 of the front subframe and the lower plate 2 of the front subframe. The upper plate 1 of the front subframe has a downward flange 11, and the The lower flange 11 extends to the lower panel 2 of the front subframe so that the upper panel 1 of the front subframe and the lower panel 2 of the front subframe enclose a rectangular box structure, and the front subframe The rear of the assembly is curved. The front part of the front subframe assembly has two opposite protrusions 3, the transition between the front part of the front subframe assembly and the protrusions 3 is smooth, and the front mounting frame 4 is arranged on on the protruding part 3. Both sides of the front subframe assembly are respectively provided with side connecting parts 5, and side connecting parts 5 are provided with side connecting holes 51. The front subframe upper plate 1 and...

Abstract

The invention relates to an automobile front subframe assembly, and belongs to the technical field of automobile frames. An upper plate of the front subframe is provided with a downward lower flanging, the lower flanging extends to a lower plate of the front subframe to enable the upper plate of the front subframe and the lower plate of the front subframe to be enclosed into a rectangular box bodystructure, and a reinforcing edge extending in the horizontal direction is further arranged at the bottom of the lower flanging at the front part of the upper plate of the front subframe; an extension part matched with the reinforcing edge is arranged at the front part of the lower plate of the front subframe, and the reinforcing edge is fixedly connected with the extension part; two mounting grooves with opposite positions are separately formed in both side parts of the front subframe assembly, and front mounting frames are fixedly installed in the mounting grooves; and each front mounting frame is formed by splicing two half frames, and a plurality of supporting pieces are arranged in the two half frames.

Description

technical field [0001] The invention belongs to the technical field of automobile frame, in particular to a front auxiliary frame. Background technique [0002] The subframe is the skeleton of the front and rear axles and is an integral part of the front and rear axles. The sub-frame is not a complete frame, but a bracket that supports the front and rear axles and suspension, so that the axle and suspension pass through it and then connect with the "main frame". It is customarily called "sub-frame". The sub-frame includes the front sub-frame Frame and Rear-Front Subframe, Front Subframe and Rear-Front Subframe are all important parts of a car's chassis. As an important support structure that provides installation positions for components such as stabilizer bars, steering gear, engine mounts, and swing arms, the subframe is a key force-bearing component. NVH (Noise, Vibration, Harshness) performance refers to the performance of the car in terms of noise, vibration and harsh...
