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

[0026] Such as figure 1 Shown: an air-cooled shock absorber, including a shock absorber body 1 and a number of heat sinks 2 arranged outside the body 1, the heat sink 2 is an annular fin structure, and is evenly arranged outside the body 1 .

Embodiment 2

[0028] The difference between this embodiment and Embodiment 1 is that: the body 1 is provided with a heat dissipation cylinder 3, and the heat dissipation cylinder 3 is fixedly sleeved outside the body 1 through fixing parts 4 such as bolts, rivets or sealing rings, so that The cooling fins 2 are arranged on the cooling tube 3, and thermal conductive silicon grease is filled between the cooling tube 3 and the shock absorber body 1, and the cooling fins 2 are provided with reinforcing ribs connecting each cooling fin.

Embodiment 3

[0030] Such as figure 2 , image 3 Shown: an air-cooled shock absorber, including a shock absorber body 1 and a number of cooling fins 2 arranged outside the body 1, the cooling fins 2 are on the same plane as the central axis of the body 1, and The central axis is the central line and is distributed radially.

Abstract

The invention discloses an air-cooled shock absorber which comprises a shock absorber body and a plurality of radiating fins distributed outside the body. The radiating fins made of aluminum foils or copper aluminum alloy and the like have fine heat-conducting property are arranged outside the cylinder wall of the shock absorber body, heat generated by the shock absorber is conducted to the radiating fins through fine heat transfer effects of the shock absorber body and the radiating fins and is dissipated by air flow through large-area contact of the radiating fins and air, so that the shock absorber is effectively cooled and works under a fine working condition, carbonization or volume expansion of oil in the shock absorber is avoided, accidents such as oil leakage are decreased, 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 an air-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 fa...
