Description

Technical Field

[0001] The utility model relates to the technical field of air suspensions, in particular to a trailer air suspension shock absorbing device. Background Art

[0002] The suspension is one of the important assemblies on the car. It connects the frame and the wheels elastically. Its main task is to transmit all forces and moments acting between the wheels and the frame, and to buffer the impact force transmitted to the frame by the uneven road surface and reduce the vibration caused thereby, so as to ensure that the car can run smoothly. The traditional trailer air suspension shock absorption device usually includes an airbag suspension system and a shock absorber. In these devices, the heat dissipation problem of the shock absorber has always been an important challenge. Since the shock absorber is affected by factors such as friction and compression during operation, a certain amount of heat will be generated. If the shock absorber cannot effectively dissipate this heat, it may lead to performance degradation, shortened life or even damage.

[0003] Therefore, we propose a trailer air suspension shock absorbing device. Utility Model Content

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a trailer air suspension shock absorbing device.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a trailer air suspension shock absorbing device, including a trailer air suspension and a trailer wheel, a placement cavity is opened on one side of the trailer air suspension, a shock absorber is installed on the trailer air suspension, a slot is opened on the trailer air suspension, a side wall and a bottom of the shock absorber are respectively opened with a plurality of first through holes and a second through holes, a heat dissipation fan is fixedly connected at the center position of the inner cavity of the placement cavity, two air outlet ends of the heat dissipation fan are connected with connecting pipes, and air outlets are connected on the side wall surfaces of the two connecting pipes.

[0006] Preferably, a heat dissipation fin with an annular structure is fixedly connected to the top of the shock absorber.

[0007] Preferably, the connecting pipe is of L-shaped structure, and the air outlet is arranged on the side wall surface of the connecting pipe close to the shock absorber.
