Problems solved by technology

[0003] The traditional subframe is connected with other parts through welding sleeves. Due to the existence of welding deformation, the dimensional accuracy of the subframe is difficult to control in this structure, resulting in a large installation position of other parts on the subframe. On the other hand, due to the existence of welding heat, the brittleness of sheet metal materials will be strengthened, which will easily lead to material fatigue cracks.
[0004] Due to the application of too many welding processes, the traditional sub-frame will consume more welding materials and increase labor cost

Example Embodiment

[0044] Example

[0045] In the present invention, because the steering gear installation sleeve, stabilizer bar installation sleeve, and subframe have the same structure as the limit bosses in the body installation sleeve, here only the subframe and the body installation sleeve are The structure of the limiting boss is described in detail, and the others are the same as the structure.

[0046] The sub-frame upper plate is provided with a first mounting hole for the sub-frame and the body mounting sleeve, and the sub-frame lower plate is provided with the sub-frame and the body at the position corresponding to the first mounting hole of the sub-frame and the body mounting sleeve Install the second mounting hole of the sleeve; each mounting hole is punched to form three limit bosses at a time. The number of limit bosses can be changed as needed, but there are at least three limit bosses. The limit boss on the upper plate of the frame protrudes toward the lower plate of the subframe,...

Abstract

The invention relates to an auxiliary frame mechanism of an automobile, which comprises an auxiliary frame upper plate, an auxiliary frame lower plate, a steering engine mounting sleeve, a stabilizer bar mounting sleeve and an auxiliary frame and automobile body mounting sleeve, wherein both the auxiliary frame upper plate and the auxiliary frame lower plate are provided with steering engine mounting sleeve mounting holes, stabilizer bar mounting sleeve mounting holes and auxiliary frame and automobile body mounting sleeve mounting holes; limiting bosses/a limiting boss protruding towards the auxiliary frame lower plate are/is arranged on the peripheries/periphery of the steering engine mounting sleeve mounting hole and/or the stabilizer bar mounting sleeve mounting hole and/or the auxiliary frame and automobile body mounting sleeve mounting hole of the auxiliary frame upper plate; and limiting bosses/a limiting boss protruding towards the auxiliary frame upper plate are/is arranged on the peripheries/periphery of the steering engine mounting sleeve mounting hole and/or the stabilizer bar mounting sleeve mounting hole and/or the auxiliary frame and automobile body mounting sleeve mounting hole of the auxiliary frame lower plate.

Description

technical field [0001] The invention belongs to the technical field of automobile chassis and chassis, in particular to an automobile front sub-frame mechanism used for connecting a vehicle body. Background technique [0002] As an important load-bearing part of the car, the subframe supports and connects multiple parts of the car, including key components such as the steering mechanism, powertrain, and stabilizer bar assembly. Its fatigue life and dimensional accuracy play a vital role in the safety and performance of the vehicle. [0003] The traditional subframe is connected with other parts through welding sleeves. Due to the existence of welding deformation, the dimensional accuracy of the subframe is difficult to control in this structure, resulting in a large installation position of other parts on the subframe. On the other hand, due to the existence of welding heat, the brittleness of sheet metal materials will be strengthened, which will easily lead to material fa...
