[0002] At present, automotive suspensions are divided into passive suspensions, semi-active suspensions, and active suspensions; among them, the adjustable damping force of the damper of the semi-active suspension and the adjustable operating force of the active suspension can greatly improve the comfort of the car , thus becoming the future development direction of automobile suspension; but whether it is a semi-active suspension or an active suspension, its cooling problem is an important factor that reduces the performance of the suspension
At the same time, the semi-active suspension consumes little energy and is easy to adjust the damping, which has attracted the attention of researchers. However, its performance is not as good as that of the active suspension, because the damper can only generate damping force passively, but cannot actively generate power. Therefore, its adjustment effect on vehicle vibration is not as good as that of active suspension; active suspension has a force actuator that can actively generate force to optimize the vibration characteristics of the suspension. However, the actuator often needs to consume a lot of vehicle energy. Therefore, Difficult to popularize and apply in automobiles

Embodiment Construction
[0034] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and contribute to its implementation.
[0035] Such as Figure 1 to Figure 4 As shown, a self-cooling magneto-rheological damper of the present invention is used in automobile suspension. The magneto-rheological damper includes a damper body 3 as a damping element. The damper body 3 includes a hollow cylinder 37, a first piston 33 disposed in the cylinder 37, and a first piston inserted into the cylinder 37. The piston rod 34 connected by 33 and the exciting coil 31 arranged on the first piston 33. The magneto-rheological damper also includes a cooling device connected to the damper body 3. Since the damper body 3 has a magneto-rheolo...

The invention discloses a self-cooling magneto-rheological damper. The self-cooling magneto-rheological damper comprises a damper body, wherein the damper body comprises a cylinder barrel, a first piston, a piston rod and a magnet exciting coil, the cylinder is internally hollow, the first piston is arranged in the cylinder barrel, the piston rod is connected with the first piston and inserted in the cylinder barrel, and the magnet exciting coil is arranged on the first piston; the magneto-rheological damper further comprises a cooling device connected with the damper body. According to the magneto-rheological damper, the cooling device connected with the damper body is arranged and can cool the damper body, so that it is avoided that the use performance is affected because the temperature of the damper body is too high.
