Description
Technical Field
The utility model belongs to the technical field of car front truck sub vehicle frame assembly accessory, especially, relate to a preceding control arm.
Background
The front suspension control arm of the automobile belongs to a suspension guide part, is connected with a frame and a steering knuckle, and plays a role in transferring force and moment of wheels and an automobile body and ensuring that the wheels jump relative to the whole automobile in a certain motion track. At present, most of manufacturing processes of vehicle McPherson front suspension control arms adopt a traditional stamping and machining mode to form a spliced control arm structure, and the connection and installation of the vehicle front suspension control arms, a vehicle body and wheels adopt a three-end connection mode, namely, one end of each front suspension control arm is connected with the wheels, and the other two ends of each front suspension control arm are connected with a load-bearing vehicle body. But the bearing capacity of the existing control arm is relatively weak, the control arm is not easy to take in welding, the plate materials are wasted, the product performance strength is low, meanwhile, the sleeve welding part is low in strength and easy to deform, the safety coefficient of the automobile is reduced after the product is installed, and the technical problem of great potential safety hazard exists.
In view of this, the present invention is especially provided.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the prior art, the utility model aims at providing a preceding control arm strengthens the safety index of car, reaches the lightweight design and reduces panel waste simultaneously, strengthens structural strength again when reducing raw materials cost, environmental protection and energy saving.
In order to realize above-mentioned purpose, the utility model provides a pair of preceding control arm, including being curved preceding control arm body, the both ends of preceding control arm body are bush end and ball pin link end respectively, inwards sunken formation recess between bush end one and the ball pin link end, the recess is equipped with technology wash port, welding locating hole, technology via hole, light bracket mounting hole and technology wash port from the bush end to ball pin link end orientation in proper order, the bush end is equipped with the through-hole that is used for installing the pressure hinge, ball pin link end is equipped with bulb pin mounting hole, is in the outside extension of preceding control arm body outer arc department between technology via hole and the light bracket mounting hole forms the technology boss that has the technology swell, the opening direction of technology boss is downward and opposite with groove opening direction.
Preferably, the number of the light bracket mounting holes is two;
preferably, the number of the ball stud assembling holes is three, and the ball stud assembling holes are distributed in a triangular shape;
preferably, the front control arm body is made of a high-strength plate SZBS 800;
preferably, the front control arm body is integrally formed by punching.
The utility model provides a pair of preceding control arm has following beneficial effect:
the utility model discloses effectively avoided the bearing capacity that prior art exists low, structural strength is on the low side, there is the potential safety hazard in traveling, and the welding is difficult for taking, useless rate is high, cause the extravagant technical problem of sheet material, be the poroid technology via hole of opposite sex through the increase, make preceding control arm body easily take when the welding, it is extravagant to reduce the sheet material, design into the decurrent technology boss of opening with the sleeve simultaneously, through increase the technology swell on the technology boss, make its performance and intensity have very big increase, prevent that the product from warping, reinforcing car factor of safety, make the car reach the lightweight, energy-conservation is the environmental protection again, simple structure portation, increase overall structure intensity when reducing raw materials cost.
