Description

Technical Field

[0001] The utility model relates to the technical field of automobile shock absorbers, in particular to an automobile shock absorber device which can be quickly disassembled and repaired. Background Art

[0002] Hydraulic shock absorbers are widely used in automobile suspension systems. The principle is that when the frame and the axle make reciprocating relative motion and the piston moves back and forth in the cylinder of the shock absorber, the oil in the shock absorber housing repeatedly flows from the inner cavity through some narrow pores to another inner cavity. At this time, the friction between the liquid and the inner wall and the internal friction of the liquid molecules form a damping force on the vibration.

[0003] Shock absorbers are vulnerable parts during the use of automobiles. The quality of shock absorbers will directly affect the smoothness of the car's driving and the life of other parts. Therefore, we should keep the shock absorbers in good working condition. Therefore, it is necessary to disassemble part of the shock absorbers when checking or replacing them. Application number: 202121674334.9, discloses a quick-replacement and repair automobile shock absorber. The magnet inside the special bolt adsorbs the part that needs to be fixed, and the special bolt is fixed through the tightening mouth at one end of the special bolt or inserted into the round groove through the round rod. The special screw is rotated to fix the circular fixing plate to the bottom of the car. When the device needs to be disassembled for maintenance, the hexagonal clamping rod can be removed, and the arc clamping block can be rotated out of the sealing strip by rotating the sleeve, and taken out from the arc clamping groove to disassemble the main body of the device.

[0004] In the prior art, when the automobile shock absorber works at high intensity, the oil temperature inside the shock absorber will rise. The high temperature will cause the shock absorber oil to expand, causing the seals to age and be damaged, thereby causing oil leakage. At the same time, it will also cause the throttle hole to wear and become larger, affecting the damping effect of the shock absorber.

[0005] Based on this, a vehicle shock absorber device capable of rapid disassembly and maintenance is now provided, which can eliminate the drawbacks of the existing device. Utility Model Content

The setting of the power rod 3 facilitates the transmission of energy generated by the car during bumping and facilitates the operation of the shock absorber. A mounting bracket 4 is fixedly connected to the bottom of the power rod 3. The setting of the mounting bracket 4 facilitates the installation of the entire shock absorber device. Two mounting holes 5 are provided on the surface of the mounting bracket 4. A spring upper seat 8 is fixedly connected to the top of the shock absorber body 1, and a damping spring 9 is fixedly connected to the bottom of the spring upper seat 8; the buffer unit is arranged on the top of the spring lower seat 2, and is used to protect the shock absorber from wear and tear, and to prevent the damping spring 9 from being seriously worn and thus causing a decrease in the shock absorption effect; the cooling component is arranged on the top of the shock absorber body 1, and is used to cool the shock absorber body 1, and to prevent the shock absorber from aging and damage to the seal due to the expansion of oil at high temperature;

[0033] In one embodiment, Figure 2 As shown, the buffer unit includes two damping plates 6 stacked together, the two damping plates 6 are fixedly connected to the top of the spring lower seat 2, the tops of the two damping plates 6 are fixedly connected with spring baffles 7, the tops of the spring baffles 7 are fixedly connected to the bottom ends of the damping springs 9, the two damping plates 6 are made of polymer materials, and the spring baffles 7 and the damping springs 9 are made of high carbon steel;

[0034] The two damping sheets 6 are provided to reduce noise and vibration, and the spring baffle 7 is provided to prevent the damping spring from rushing out of the transmission position, thereby ensuring the stability of the vehicle.

[0035] In one embodiment, Figure 4 As shown, the cooling component includes a dust cover 10 with a filter screen, the dust cover 10 is fixedly connected to the top of the spring upper seat 8, the top of the dust cover 10 is fixedly connected to a cylinder cavity 11, and the interior of the cylinder cavity 11 is provided with a water circulation component for cooling the shock absorbing body 1.

[0036] The dust cover 10 is provided to prevent excessive dust and dirt from adhering to the shock absorber when the car is driving, thereby corroding the shock absorber and reducing the service life of the shock absorber. The cylinder cavity 11 is provided to facilitate the installation of the water tank 12 and also protect the internal structure.

[0037] In one embodiment, Figure 4As shown, the water circulation component includes a water tank 12, which is fixedly connected to the inner wall of the cylinder cavity 11, and the inner wall of the water tank 12 is slidably connected with a piston 13 adapted thereto. A cooling pipe 14 is wound around the surface of the shock absorbing body 1, and both left and right ends of the cooling pipe 14 penetrate the bottom of the spring upper seat 8 and extend to the interior of the cylinder cavity 11. One end of the cooling pipe 14 is connected to the left side of the water tank 12, and the other end is connected to the right side of the water tank 12.
