Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a damping shock absorber with adjustable installation angle. Background Art

[0002] In the suspension system of a car, elastic elements vibrate due to impact. In order to improve the driving smoothness of the car, shock absorbers are generally installed in parallel with elastic elements to suppress the shock caused by the rebound of the spring after shock absorption and the impact from the road. The lower end of the shock absorber is generally connected to the axle through a pin shaft to keep it fixed, and the upper end is generally fixed to the shock absorber seat through 3 to 4 fasteners. The load generated by the impact of the road is transmitted to other parts through the shock absorber. The installation angle and the size of the fasteners of each car are different, and the interchangeability is poor. Therefore, the design of the shock absorber and the mounting seat needs to meet certain accuracy and strength requirements. Once designed, the installation angle and damping force are fixed.

[0003] During the driving process of the car, the bouncing of the wheels will cause the car suspension to move together. During the process, the shock absorber will experience extension, contraction, twisting and other rotation states. When in the twisting state, the shock absorber will also twist. If the twisting cannot be released, it will accelerate the failure of the shock absorber, thereby reducing the service life of the shock absorber.

During installation, the bearing 18 in the mounting seat 19 is used to adjust the installation angle of the shock absorber. When vibration occurs, the torsion generated in the process can be released.

There are three riveted mounting bolts on the upper mounting seat 19, and the upper end of the shock absorber is connected to the vehicle body with a second flange nut 24. When the vehicle moves relative to the vehicle due to vibration, the piston inside the shock absorber will reciprocate in the cylinder, and the oil will repeatedly flow from one cavity to another through different small holes to form a damping force.

[0026] If a torsion state occurs during driving, the torsion state will be fine-tuned and the torsion force will be released at the same time, thereby extending the service life of the shock absorber. At the same time, an electrical control structure is added to the shock absorber to change the damping of the shock absorber according to road conditions during driving, thereby achieving free switching between the "hard suspension" and "soft suspension" states, thereby improving driving comfort.

[0027] The utility model adopts a rotatable mounting seat 19 to match the installation requirements of different installation angles and hole distances at one time, and adopts a CDC assembly 30 for adjustment to improve the accuracy and increase the controllability to fine-tune the shock absorber, thereby achieving the function of meeting different installation angles and extending the service life.
