Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical engineering, and particularly relates to a shock absorber for special vehicles. Background Art

[0002] Special vehicles refer to various special tank trucks, various special motor vehicles, and van motor vehicles; or motor vehicles equipped with fixed special instruments and equipment inside for monitoring, fire fighting, cash transportation, medical treatment, television relay, radar, X-ray inspection, etc. engaged in professional work. Special vehicles are designed based on the structural characteristics of the vehicle itself. Compared with the traditional structural form of the chassis of ordinary trucks, the chassis and the overall structure of the vehicle are quite special, specially designed, and rarely use general-purpose assembly parts.

[0003] At present, an existing shock absorber for special vehicles does not have an installation mechanism. The shock absorber may not be firmly fixed on the vehicle, resulting in easy loosening or falling off during driving, thus affecting the safety and stability of the vehicle. The shock absorber with unstable installation may fall off during vehicle driving, causing serious safety hazards and even possible traffic accidents. At the same time, due to the lack of a firm installation, the performance of the shock absorber may gradually decline over time, resulting in a poor shock absorption effect after long-term use of the vehicle.

The installation mechanism is arranged around the upper mounting plate. The installation mechanism includes a round hole, an installation thread groove, and an installation bolt. The round hole is opened inside the periphery of the upper mounting plate. The installation thread groove is arranged inside the round hole. The installation bolt is threadedly connected inside the round hole and threadedly connected with the installation thread groove.

[0007] As a preferred solution of the utility model, a shock absorption mechanism is arranged at the bottom of the upper mounting plate.

[0009] As a preferred embodiment of the present utility model, rectangular plates are movably connected to the outer sides of the bottom of the upper movable block and the top of the lower movable block. Square notches are formed in the inner sides of the rectangular plates, and the square notches are movably connected to the upper movable block and the lower movable block respectively.

[0010] As a preferred embodiment of the present utility model, circular grooves are formed in the four circumferences of the inner side of the rectangular plate. Fixed frames are fixedly connected to the left and right ends of the inner side of the rectangular plate. Frame threaded grooves are formed in the inner sides of the top and bottom of the fixed frame.

A lower fixing shaft is fixedly connected to the inner side of the lower fixing plate, and the lower fixing shaft is movably connected to the lower circular ring sleeve frame.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. For this special vehicle shock absorber, by setting the installation mechanism, it can effectively ensure the stability of the shock absorber during the use of the device in the vehicle driving process, prevent it from shifting or falling off when being impacted. The installation threaded groove allows the installation bolt to rotate and adjust within a certain range, and the position of the shock absorber can be finely adjusted according to the actual needs of the vehicle and the installation space to achieve the best installation effect and shock absorption performance. The design of the installation bolt also facilitates the disassembly and maintenance of the shock absorber.

[0015] 2. This special vehicle shock absorber can effectively absorb and buffer the vertical impact force generated during vehicle driving by setting up a shock absorption mechanism. When the vehicle is driving on an uneven road surface, the spring reduces the vibration transmitted to the vehicle body through its elastic deformation, thereby improving the riding comfort. After the spring absorbs the impact force, the shock absorber controls the rebound speed of the spring through its internal damping mechanism to prevent the spring from rebounding excessively and causing vehicle instability, ensuring the smoothness of the vehicle during driving. Through the coordinated work of the spring and the shock absorber, the shock absorber can effectively reduce the vibration and impact suffered by the vehicle during driving, thereby improving the driving stability of the vehicle, which is particularly important for special vehicles because they often need to work under harsh road conditions or high-speed driving conditions.

[0040] Working principle:

[0041] When in use, fix the upper mounting plate 1 to the designated position of the special vehicle. Use the mounting bolts 203 to firmly fix the upper mounting plate 1 to the special vehicle through the circular holes 201 and the mounting threaded grooves 202. Fix the lower mounting plate 18 to another designated position of the special vehicle, ensuring that the lower mounting plate 18 is aligned with the upper mounting plate 1. Fix the upper movable block 301 to the bottom of the upper mounting plate 1, fix the lower movable block 303 to the top of the lower mounting plate 18, install the spring 302 between the upper movable block 301 and the lower movable block 303, ensure that the shock absorber 304 is correctly installed inside the spring 302 and fixedly connected to the lower movable block 303. Connect the upper fixing plate 4 to the front and back of the left and right ends at the bottom of the upper mounting plate 1. Install the upper fixing shaft 5 inside the upper fixing plate 4, sleeved the upper circular ring sleeve 6 on the front and back of the upper fixing shaft 5, and ensure its movable connection. Install the rectangular plate 7 on the outer sides of the bottom of the upper movable block 301 and the top of the lower movable block 303, ensure that the square notch 9 of the rectangular plate 7 is movably connected to the upper movable block 301 and the lower movable block 303. Open circular grooves 8 around the inside of the rectangular plate 7, fix the fixing frame 10 to the left and right ends inside the rectangular plate 7, thread the fixing bolts 12 through the circular grooves 8 and the frame threaded grooves 11 of the fixing frame 10. Open sliding rectangular grooves 13 at the top and bottom of the fixing frame 10 and install sliders 14. Fix the inner fixing shafts 15 to the front and back of the sliders 14, fix the limit discs 16 to the front and back of the inner fixing shafts 15, and ensure that the inner fixing shafts 15 are movably connected to the upper circular ring sleeve 6 and the lower circular ring sleeve 17.

Install the lower fixing shaft 20 inside the lower fixing plate 19 and ensure its movable connection with the lower circular ring sleeve 17.

[0042] In summary: The round holes 201, installation threaded grooves 202, and installation bolts 203 contained inside the installation mechanism 2 can ensure the stability of the shock absorber during vehicle operation, preventing displacement or detachment during impact. The installation threaded grooves 202 allow the installation bolts 203 to rotate and adjust within a certain range, enabling fine-tuning of the shock absorber's position according to the actual needs of the vehicle and the installation space to achieve the best installation effect and shock absorption performance. The design of the installation bolts 203 also facilitates the disassembly and maintenance of the shock absorber. When inspection, repair, or replacement of the shock absorber is required, quick disassembly can be achieved by loosening the installation bolts 203 without the need for destructive disassembly. The springs 302 and shock absorbers 304 contained inside the shock absorption mechanism 3 can absorb and buffer the vertical impact forces generated during vehicle operation. When the vehicle is driving on an uneven road surface, the springs 302 reduce the vibrations transmitted to the vehicle body through their elastic deformation, thereby improving ride comfort. After the springs 302 absorb the impact forces, the shock absorbers 304 control the rebound speed of the springs 302 through the damping mechanism inside to prevent excessive rebound of the springs 302 and ensure vehicle stability during driving. Through the coordinated operation of the springs 302 and shock absorbers 304, the shock absorber can effectively reduce the vibrations and impacts received by the vehicle during driving, thereby improving the driving stability of the vehicle, which is particularly important for special vehicles as they often need to operate under harsh road conditions or at high speeds.
