Problems solved by technology

However, its disadvantage is that the water absorption capacity of the water-absorbing parts is limited. Once the water evaporates, it is not only difficult to effectively cool down the shock absorber, but also seriously affects the ventilation and heat dissipation on the surface of the shock absorber, aggravating the temperature rise, and reducing the temperature of the shock absorber. The vibrator causes harsh working conditions, which seriously affects the service life of the shock absorber

Embodiment 1

[0025] Such as figure 1 Shown: a water-cooled shock absorber, including a shock absorber body 1 and a water jacket 2 arranged outside the body 1, and the water jacket 2 is provided with a water inlet 5 and a water outlet 4. Both the inner wall of the water jacket 2 and the outer wall of the body 1 are provided with partitions 3 , and the water jacket 2 is a metal part welded with the body 1 as an integral structure.

Embodiment 2

[0027] Such as figure 2 Shown: a water-cooled shock absorber, including a shock absorber body 1 and a water jacket 2 arranged outside the body 1, the outer body 1 is set with a cooling tube 10, and the water jacket 2 and the cooling tube 10 is an integral structure, and both ends of the heat sink 10 are crimped on the body 1 through the ring piece 6 . The gap between the inner wall of the heat sink 10 and the body 1 is filled with thermal conductive silicone grease. The water jacket 2 is provided with a water inlet 5 and a water outlet 4 . A partition 3 is arranged in the water jacket 2, and both the water inlet 5 and the water outlet 4 are connected with the automobile water circulation system. Both the water jacket 2 and the heat sink 10 are metal parts with good thermal conductivity.

Embodiment 3

[0029] Such as image 3 , Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the water jacket 2 is made of cold-resistant, heat-resistant and pressure-resistant (PP+EPDM) rubber material, and a diaphragm 31 is arranged inside the water jacket 2, so that The two ends of the water jacket 2 are hermetically connected to the body 1 through a sealing member, the sealing member is a sealing ring, and the sealing ring includes an inner ring 7, an outer ring 8 and a ring arranged between the inner ring 7 and the outer ring 8 The cross-section is a sloped annular structure 9 with a triangular structure. The inner ring 7 has a slope structure that fits with the sloped ring structure 9. When sealing, first put the inner ring 7 on both ends of the water jacket 2, and then place the slope The ring structure 9 is placed between the water jacket 2 and the body 1, and the outer sleeve 8 is threadedly connected with the inner ring 7. By tightening the outer ri...

Abstract

The invention discloses a water-cooled shock absorber. The water-cooled shock absorber comprises a shock absorber body and a water jacket which is arranged outside the shock absorber body, wherein a water inlet and a water outlet are formed in the water jacket. According to the water-cooled shock absorber, the water jacket allowing water flow to pass is arranged outside the cylindrical wall of the shock absorber body, heat of the high-temperature shock absorber body is transmitted to low-temperature water in the water jacket through heat transmission conducted when the low-temperature water flows through the water jacket, heat is taken away through the circulating flowing of the water, in this way, effective cooling of the shock absorber is achieved effectively, the shock absorber operates in a good working condition, carbonization of oil in the shock absorber or volume expansion of the shock absorber is avoided, the occurrence rate of accidents such as oil leakage is reduced, and the service life of the shock absorber is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of temperature reduction and cooling of shock absorbers, in particular to a water-cooled shock absorber. Background technique [0002] The shock absorber is the main damping element of the vehicle suspension system. It plays the role of accelerating the attenuation of the vibration of the frame and the body to improve the ride comfort and comfort of the vehicle. Generally speaking, the damping mainly comes from the throttling of the small hole of the liquid in the cylinder. The mechanical energy generated by the vibration is converted into heat energy after the throttling of the small hole, which makes the temperature of the liquid in the shock absorber rise and the viscosity of the liquid changes. The damping size of the shock absorber will cause a large change in the performance of the shock absorber. The higher the temperature, the lower the damping, the worse the damping performance, and even gradually f...
