Description
Technical Field
The utility model relates to an automobile suspension spare part field, concretely relates to control arm under extrusion aluminium alloy.
Background
The existing lower control arm of a rear suspension of a passenger vehicle, particularly the lower control arm of the rear suspension of a heavy-load passenger vehicle, is mainly manufactured by adopting the following schemes:
firstly, a hollow structure is formed by stamping and welding a steel plate;
secondly, a solid or hollow structure is cast by adopting aluminum alloy;
thirdly, adopting a solid structure forged by aluminum alloy;
in the above schemes, although the cost of a single piece is low, the overall weight is large and the cost of the die is high; compared with the first scheme, the second scheme has certain weight reduction effect, but the cost is high, and the yield is low due to casting defects; the third scheme has compact metallographic structure and higher strength, but is limited by a forging process, cannot realize the manufacture of the lower control arm with a complex shape and has high cost.
Disclosure of Invention
The utility model aims at providing a control arm under extrusion aluminium alloy is personally submitted pi font through the structure cross-section and promotes rigidity 50% and bucking stress 50%, has improved the intensity and the rigidity of control arm down, the cost is reduced.
The purpose of the invention is realized by the following technical scheme:
the utility model provides a control arm under extrusion aluminium alloy, includes control arm main part down, the main part on with sub vehicle frame installation side be provided with bush mounting hole 1, with knuckle installation side be provided with fixed ear 5, be provided with local bulge structure 4 in the main part that shock absorber mounted position corresponds, be provided with first punching press hole 2 in the main part that cushion installation cooperation position corresponds under the spring and be used for installing the cushion, be provided with second punching press hole 3 in the main part that cushion corresponds under the spring and be used for the installation location, fixed ear 5 between be provided with straight section structure 6, the section structure of main part be "pi" font.
The beneficial effects are as follows:
the utility model provides a lower control arm structure is different from control arm under the aluminium alloy among the prior art, and it is high to have structural strength, but low in production cost is efficient, the advantage that product yield is high, and the improvement of structure has brought rigidity promotion 50%, and buckling stress promotes 50%, technical effect that the cost is reduced 5% to adopt extrusion aluminium alloy stamping forming technology, the selection of material has brought the weight and has reduced thirty technical effect of percent.

Detailed Description
The invention will be described in further detail with reference to the drawings, in which like parts are designated by like reference numerals throughout the different views and are generally described only once.
As shown in fig. 1, the utility model provides a control arm under extrusion aluminium alloy is applicable to the independent back suspension system of multi-link formula, including control arm main part down, the main part on with sub vehicle frame installation side be provided with bush mounting hole 1, with knuckle installation side be provided with fixed ear 5, be provided with local bulge structure 4 in the main part that shock absorber mounted position corresponds, be provided with first punching press hole 2 in the main part that cushion installation cooperation position corresponds under the spring and be used for installing the cushion, be provided with second punching press hole 3 in the main part that the cushion corresponds under the spring and be used for the installation location, fixed ear 5 between be provided with straight section structure 6, the A-A section structure of main part be "pi" font.
Lower control arm adopt extrusion aluminium alloy stamping structure, through technologies such as section bar extrusion, scale slitting saw, profile blanking, turn-ups, bending, punch a hole and carry out machine-shaping. The lower control arm can be provided with a spiral spring or an air spring, and can be provided with a traditional shock absorber or a shock absorber with continuously adjustable damping force. The lower control arm can meet the requirements of different bearing capacities of the modularized platform vehicle type by increasing or reducing the thickness of the pi-shaped section. The lower control arm is provided with a straight section structure between two mounting holes of the fixing lugs on the same side, and the change requirement within 25mm of the wheel base on the single side of the modularized vehicle type is met by adjusting the length of the straight section.
The utility model discloses an installation as follows: the mounting side of the auxiliary frame and the mounting side of the auxiliary frame are in a bushing mounting hole 1 structure, and an aluminum sleeve is pressed at the punching position of the section body and is flanged and fixed; and the mounting side of the steering knuckle is of a fixed lug 5 structure, and the structure is connected with a steering knuckle bushing through local embossing and punching molding of the profile body, so that the fastening stress is favorably reduced. The local embossing structure 4 is a shock absorber mounting position. Punching press hole 2 is cushion installation cooperation position under the spring, and punching press hole 3 is cushion installation locating hole under the spring.
