Description

Technical Field

[0001] The utility model relates to the technical field of vehicle shock absorbers, in particular to an adjustable shock absorber upper bracket. Background Art

[0002] A shock absorber is used to suppress the oscillation when the spring rebounds after absorbing shock and the impact from the road surface. It is widely used in automobiles to accelerate the attenuation of the vibration of the vehicle frame and the body, so as to improve the ride comfort of the vehicle. When passing through an uneven road surface, although the shock-absorbing spring can filter the road vibration, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jump.

[0003] In the vehicle suspension system, due to the vibration generated by the elastic element being impacted, in order to improve the ride comfort of the vehicle, a shock absorber is installed in parallel with the elastic element in the suspension. To attenuate the vibration, most shock absorbers used in the vehicle suspension system are hydraulic shock absorbers. Its working principle is that when the vehicle frame (or body) and the axle vibrate and relative movement occurs, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly flows from one cavity through different pores into another cavity. At this time, the friction between the hole wall and the oil and the internal friction between the oil molecules form a damping force on the vibration, converting the vehicle vibration energy into oil heat energy, which is then absorbed by the shock absorber and dissipated into the atmosphere. When the cross-sectional area of the oil passage and other factors remain unchanged, the damping force increases or decreases with the relative movement speed between the vehicle frame and the axle (or wheel), and is related to the viscosity of the oil.

[0004] It can be seen that the shock absorber adjusts the vehicle vibration by converting the vehicle mechanical energy into heat energy, thereby improving the driving comfort, and is an essential component of the suspension system. However, in the actual use process, the installation hole position of the shock absorber upper bracket is fixed, and the applicable range is small. When matching different suspensions and axles, the axle jump amount changes, or there is an error between the actual axle jump and the design during the vehicle use. In the above situations, there are risks such as the shock absorber being pulled and damaged or compressed and jammed, which not only affects the vehicle ride comfort but also greatly reduces the service life of the shock absorber. Summary of the Utility Model

The diameter of the stepped platform is larger than the diameters of the shock absorber connecting rod and the bracket connecting rod, so that a stepped structure can be formed between the stepped platform and the shock absorber connecting rod, and between the stepped platform and the bracket connecting rod.

[0007] A further improvement of the present utility model is that the bracket body is a C-shaped frame. The adjustment holes A are provided on the closed side of the bracket body. An extension plate is provided on the open side of the bracket body.

[0015] A further improvement of the present utility model is that the stepped platform is a cylindrical structure, and the stepped platform, the shock absorber connecting rod, the bracket connecting rod, the screw A and the screw B are coaxially arranged.

[0016] As can be seen from the above technical solutions, the beneficial effects of the present utility model are as follows: The design of this bracket is reasonable and the structure is simple.

[0026] Specifically, the bracket body 1 is a C-shaped frame. At least three adjustment holes A101 are provided, and the three adjustment holes A101 are arranged vertically on the closed side of the bracket body 1; an extension plate 102 is provided on the open side of the bracket body 1, and two bolt holes 103 arranged symmetrically up and down are provided on the extension plate 102. A fixing bolt 6 for connecting the vehicle frame 8 is inserted into the bolt holes 103, and a fixing nut C7 is screwed on the fixing bolt 6.

[0027] During installation, the staff can install the bracket body 1 on the vehicle frame 8 through the fixing bolt 6 and the fixing nut C7, and the three adjustment holes A101 can provide different installation positions for the kingpin body 2. By adjusting the installation position of the kingpin body 2, the installation position of the shock absorber 9 can be changed.

[0028] The kingpin body 2 includes a stepped platform 201.
