Description

Technical Field

[0001] The utility model relates to the field of suspension, in particular to a suspension strut assembly. Background Art

[0002] The suspension strut assembly is a general term for all force transmission connection devices between the vehicle frame (or carrier) and the axle (or wheel). It is located between the wheel and the frame and plays an important role in transmitting power and torque. The main function of the suspension strut assembly is to transmit force and torque between the wheel and the frame, while buffering the impact force transmitted from the rough road to the frame or body, reducing the resulting vibration, and ensuring that the car can run smoothly.

[0003] However, the total length of general suspension struts cannot be adjusted. Usually, one type of strut size is determined for one vehicle model, which has poor versatility and low common platform rate. In addition, the damper oil storage cylinder is subjected to lateral force and is prone to bending under force, which affects the quality of the entire vehicle. For this reason, we have proposed a suspension strut assembly. Utility Model Content

The shock absorbing spring 4 is fixedly installed at the bottom of the suspension upper end 1, and the shock absorber 3 is fixedly installed at the bottom of the suspension upper end 1 corresponding to the inside of the shock absorbing spring 4. The suspension lower end 2 is fixedly installed at the bottom of the shock absorbing spring 4, and also includes:

[0027] The outer surface of the suspension lower end 2 is provided with a connection device for changing the installation length of the suspension support;

[0028] The outer surface of the suspension lower end 2 is provided with a handle device for quickly fixing the connecting device.

[0029] Furthermore, the interior of the suspension lower end 2 is hollow, and the bottom end of the shock absorber 3 is fixedly mounted on the inner wall of the suspension lower end 2, and the outer surface of the suspension lower end 2 is threaded.

[0030] Furthermore, the connecting device includes a connecting pipe 5, a fixed upper ring 6, a fixed lower ring 7 and bolts 16. The outer surface of the suspended lower end 2 is movably connected to the connecting pipe 5, and the top of the connecting pipe 5 is movably installed with the fixed upper ring 6 and the fixed lower ring 7 through two bolts 16.

[0031] Furthermore, the fixed upper ring 6 and the fixed lower ring 7 are both semicircular, and the inner surfaces of the fixed upper ring 6 and the fixed lower ring 7 are threaded, and one end of the fixed upper ring 6 and the fixed lower ring 7 is provided with a first connecting hole 12, and the other end of the fixed upper ring 6 and the fixed lower ring 7 is provided with a second connecting hole 14, and the outer surface of the fixed upper ring 6 is provided with an arc groove 8.

[0032] Furthermore, the handle device includes a fixed handle 9, a connecting column 10 and a first threaded nail 11. The outer surface of the fixed upper ring 6 corresponds to the inner part of the arc-shaped groove 8 and the fixed handle 9 is movably connected. One end of the fixed handle 9 is fixedly connected to the connecting column 10, and the middle end of the connecting column 10 is movably connected to the first threaded nail 11.

[0033] Furthermore, the fixed handle 9 is arc-shaped, and a movable groove is opened on one side of the fixed handle 9 , and both ends of the connecting column 10 are fixedly installed inside the movable groove, and a threaded hole 15 is opened at the middle end of the connecting column 10 .

[0034] Furthermore, one end of the first threaded nail 11 passes through the first connecting hole 12 opened in the fixed lower ring 7 and the first connecting hole 12 opened in the fixed upper ring 6 and is threadedly connected to the inside of the threaded hole 15, and one end of the second threaded nail 13 passes through the second connecting hole 14 opened in the fixed lower ring 7 and is movably threadedly connected to the inside of the second connecting hole 14 opened in the fixed upper ring 6.

[0035] Working principle: When the suspension strut needs to be connected and adjusted, firstly, the fixed upper ring 6 and the fixed lower ring 7 are installed on the connecting pipe 5 by means of the bolts 16, and then the second threaded nail 13 is twisted so that the threaded end thereof passes through the second connecting hole 14 on the fixed lower ring 7 and is threadedly installed in the second connecting hole 14 on the fixed upper ring 6, so that one end of the fixed upper ring 6 and the fixed lower ring 7 are installed together, and then the suspension lower end 2 is inserted into the interior of the connecting pipe 5, and when it is adjusted to a suitable height, the fixed handle 9 can be pulled so that the fixed handle 9 can pull the first threaded nail 13 through the connecting column 10. The nail 11 moves toward the inside of the arc-shaped groove 8, so that one end of the fixed upper ring 6 is tightly attached to one end of the fixed lower ring 7, so that the inner surfaces of the fixed upper ring 6 and the fixed lower ring 7 are tightly fixed to the outer surface of the hanging lower end 2, so that the connecting pipe 5 is quickly fixed and installed on the hanging lower end 2. At the same time, the friction between the hanging lower end 2 and the fixed upper ring 6 and the fixed lower ring 7 is increased through the threaded shape of the outer surface of the hanging lower end 2 and the threaded shape of the inner surfaces of the fixed upper ring 6 and the fixed lower ring 7, thereby preventing the fixed upper ring 6 and the fixed lower ring 7 from loosening from the hanging lower end 2.
