Existing " horn mouth " phenomenon.Driving, braking, turn, hang down and jump etc. under operating mode, control arm mount point is subject to very big loading force, one
There are the problems referred to above in denier, then torque decline, even chassis abnormal sound, bolt falling occurs, causes client to complain, or even vehicle is tight
Damage again, affect passenger safety.
The content of the invention
The purpose of this utility model is the mounting structure for proposing a kind of control arm and subframe, the control arm and subframe
Mounting structure can ensure that the flatness and the depth of parallelism of control arm installation surface, while mounting structure will not produce gap, so as to
The problems such as evading torque decline, chassis abnormal sound, the bolt falling that the problems referred to above cause.
Control arm of the present utility model includes the control of subframe, mounting bracket and trident with the mounting structure of subframe
Arm, the first linking arm of control arm, the second linking arm are flexibly connected respectively with subframe, it is critical only that the mounting bracket by two
The installing plate of side and the connecting plate of centre are integrally formed, and the section of mounting bracket is U-shaped；Both sides installing plate is provided with position pair
The installing hole answered, and the installing plate of side is welded with nut at the position of its installing hole；The upper body of the subframe and lower body
Form an open-ended trench structure；The mounting bracket is fitted and is fixedly welded in trench structure with trench structure；
The end of the second linking arm of control arm is extend in mounting bracket, and by the bolt through the second linking arm and mounting bracket
It is connected with mounting bracket.
Above-mentioned mounting bracket can ensure that the linking arm of control arm second（I.e. front mount point）Flatness, the depth of parallelism, not
Gap can be produced, is met and put before control arm intensity requirement of the stress under various operating modes to structure, so there is no need to secondary car
Frame body makes Integer Coefficients mould to ensure the requirement of fitting surface.In mounting bracket, control arm passes through bolt to nut-welding
Assemble with nut is installed, the gapless assembling mode of lamina is prevented effectively from false torque, improves effective clamping force.Above-mentioned peace
Dress supporting structure is simple, general steel punching press and bending.
Further, the connecting plate of the mounting bracket is provided with the location hole for positioning during punching press, so that punching press is installed
Position is more accurate during support.
Further, round-corner transition between the installing plate and connecting plate, and joint is provided with reinforcement, to reduce stress
Concentrate and strengthen the intensity of mounting bracket.
Further, the edge of the installing plate is provided with flange, to improve the intensity of mounting bracket.
The mounting structure of control arm of the present utility model and subframe is by setting up a mounting bracket, it is ensured that control arm
The flatness and the depth of parallelism of installation surface, and the problems such as producing torque decline, chassis abnormal sound, bolt falling is avoided, with fine
Practicality.

Specific embodiment
It is for example involved to specific embodiment of the present utility model by the description to embodiment below against accompanying drawing
The shape of each component, the mutual alignment between construction, each several part and annexation, the effect of each several part and operation principle etc. make
It is further to describe in detail.
Embodiment 1：
As illustrated, the control arm of the present embodiment includes subframe 1, mounting bracket 2 and three with the mounting structure of subframe
The control arm 3 of fork-shaped, the first linking arm 31 of control arm 3（Mount point after i.e.）, the second linking arm 32（I.e. front mount point）Respectively
It is flexibly connected by bolt with subframe 1, it is critical only that installing plate 21 and the connection of centre of the mounting bracket 2 by both sides
Plate 22 is integrally formed, and the section of mounting bracket 2 is U-shaped；Both sides installing plate 21 is provided with the corresponding installing hole 23 in position, and inner side
