Fig. 1 is a kind of upper piece schematic diagram of the rear suspension control arm for multi link formula independent suspension of the present invention.
Fig. 2 is a kind of bottom sheet schematic diagram of the rear suspension control arm for multi link formula independent suspension of the present invention.
Fig. 3 is a kind of reinforcing plate schematic diagram of the rear suspension control arm for multi link formula independent suspension of the present invention.
Fig. 4 is a kind of generalized section of the rear suspension control arm for multi link formula independent suspension of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings the invention will be further described for explanation and specific embodiment.
As shown in Figures 1 to 4, a kind of rear suspension control arm for multi link formula independent suspension, is box including mutually overlap joint
Shape structure upper piece 1 and bottom sheet 4, it is described upper piece 1 and bottom sheet 4 overlap in a plane 7, it is described upper piece 1 be provided with spring peace
Tankage, the bottom land of the spring mounting groove is provided with the first dispersive stress hole 2, and the bottom sheet 4 is provided with the installation of stabiliser bar thrust
Frame 5.
As shown in Figures 1 to 4, it is described upper piece be provided with the second dispersive stress hole 3.
As shown in Figures 1 to 4, the bottom sheet 4 is provided with flange 6.
As shown in Figures 1 to 4, the bottom sheet 4 is provided with rounding.
As shown in Figures 1 to 4, it is described upper piece three reinforcing plates 8 are provided between 1, bottom sheet 4.
As shown in Figures 1 to 4, upper piece 1 thickness is 2.5mm, and the thickness of bottom sheet 4 is 2.5mm；The depth of spring mounting groove
H1=49mm, width h2=120mm；The thickness of reinforcing plate is respectively：3mm, 3mm and 3.5mm；Curl around punching hole fillet R=5mm, turns over
Edge lengths L=3.5mm；The diameter in the first dispersive stress hole 2 is respectively D1=8mm, a diameter of D2=12 in the second dispersive stress hole 3
mm；Become Fillet Feature R1=8mm, R2=12mm, R3=10mm.
A kind of rear suspension control arm for multi link formula independent suspension that the present invention is provided has the characteristics that：
1st, the mounting surface of spring mounting groove is recessed, and pit is deeper, and such design for being characterized as spring achieves very big sky
Between.
2nd, bottom sheet 41 is overlapped with upper piece in a plane 7, it is to avoid complicated trimming during punching press to bottom sheet, up and down
The overlap joint of piece coordinates more simple.
3rd, the weld seam of fluctuating plate is in a plane 7 and tendency is regular, and welding usability is good, weldquality reliability.
4th, because the vertical load of rear overhang is mainly delivered to control arm by spring, so the spring mounting groove bottom surface of control arm
Stress is especially severe.This kind of overlap joint scheme, in the big region of stress the moment of inertia in section is increased, and the improvement to stress is more bright
It is aobvious.
5th, there is the feature of a circle flange 6 at the perforate edge of bottom sheet 4, and the inertia in section reduces stress and become apparent from away from increase,
And the maximum of stress is occurred in flange Fillet Feature, it is to avoid the stress concentration at trimming edge, the durable of structure more may be used
Lean on.
6th, reinforcing plate 8 is increased inside control arm, in the region of high stress the first dispersive stress hole 2 and the second dispersion is increased
Stress hole 3, makes stress branch more uniform.
7th, the stress level of structure is improved using rounding corner characteristics are become in the region of high stress.
A kind of rear suspension control arm for multi link formula independent suspension that the present invention is provided has advantages below：
1st, the design that spring mounting groove mounting surface sinks, increased the arrangement space of suspension miscellaneous part.
2nd, the fluctuating plate of control arm is welded into an overall box like structure, has enough rigidity and intensity to bear from wheel
Various load.
3rd, the good manufacturability of punching press and the welding of control arm, part manufacture has good stability and reliability.
4th, the reinforcing plate 8 for increasing and dispersive stress hole, make the stress branch of structure uniformly rationally, improve control arm fatigue
Endurance life.
5th, simplify structure, simplify assembling, can solve multi link arrangement space anxiety, control arm processability of product structure,
The problem of fatigue endurance.
Above content is to combine specific preferred implementation further description made for the present invention, it is impossible to assert
The present invention be embodied as be confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of without departing from present inventive concept, some simple deduction or replace can also be made, should all be considered as belonging to the present invention's
Protection domain.
