Although this connection and fixing method is simple in structure and easy to operate, it is adopted by most manufacturers, but in actual operation, because the ball stud pin is mostly made of high-strength steel, the clips that constitute the steering knuckle are mostly steel or cast iron. Therefore, the coefficient of friction between the connecting part of the ball stud and the clip provided on the steering knuckle is very small, and the ball stud will move up and down under the action of external force, even if the ball stud ball The position displacement of the hard point of the head part exceeds 1mm, which affects the performance of the control arm and suspension device

Embodiment Construction
[0009] Embodiments of the present invention will now be described with reference to the accompanying drawings.
[0010] Such as figure 1 As shown, a connection device for connecting the control arm and the shock absorber, including a ball stud 10 for connecting the control arm and a steering knuckle 20 for connecting the shock absorber, at the end of the steering knuckle 20 A clamp 21 for fixing the ball stud 10 is provided, and the connecting portion 11 of the ball stud 10 is fixedly connected to the steering knuckle 20 through the pre-tightening bolt 22 provided on the clamp 21. The ball stud 10 A friction block 30 is disposed on the inner peripheral wall of the connecting portion 11 and / or the clip 21 . By setting the friction block on the connecting portion 11 of the ball stud 10 and / or on the inner peripheral wall of the clip 21, the coefficient of friction between the clip 21 and the connecting portion 11 of the ball stud 10 is increased, preventing the ball stud 10 fro...

The invention discloses a connecting device used for connecting a control arm and an absorber. The connecting device comprises a ball head pin used for connecting the control arm and a steering joint used for connecting the absorber; a clip used for fastening the ball head pin is arranged at the tip of the steering joint; a connecting part of the ball head pin is fixedly connected with the steering joint through a pre-tightening bolt arranged on the clip; and friction blocks are arranged on the connecting part of the ball head pin and / or the inner circumference wall of the clip. In the technical scheme, the friction blocks are arranged on the connecting part of the ball head pin and / or the inner circumference wall of the clip, so as to increase the coefficient of friction between the clip and the connecting part of the ball head pin, prevent the ball head pin from moving under the action of external force and ensure a hard point position of a ball head part of the ball head pin to be fixed, so that four wheels of a hanger bracket are ensured to be positioned accurately, and the optimal use performances of the hanger bracket device and the control arm are guaranteed.
Description
technical field [0001] The invention relates to the field of automobile suspension devices, in particular to a connecting device for connecting a control arm and a shock absorber. Background technique [0002] If the car frame or body is directly installed on the axle, it will bump and vibrate up and down due to the unevenness of the road, which will make the members of the car feel uncomfortable or damage the goods. Therefore, the car must be equipped with a suspension device with buffering, vibration reduction and guiding functions. At present, most of the front suspension devices of automobiles use McPherson suspension or double wishbone suspension. No matter which of these two suspensions, it is necessary to arrange a control arm structure. The shock absorbers are connected to achieve the functions of buffering, damping and guiding the vehicle. During specific implementation, the connecting device includes a ball stud and a steering knuckle. The ball head of the ball s...
