It states one end outer wall that piston rod 2 is located in fuel tank 1 and is provided with electromagnetic coil combination, the electromagnetic coil combination includes being set in
Skeleton 3 on 2 outer wall of piston rod and the coil 4 being wrapped on the annular groove being equipped in skeleton 3,3 outer wall of skeleton and store oil
There are the clearance space passed through for magnetorheological fluid between 1 inner wall of cylinder, the cable-through hole I passed through for coil 4 is equipped in the middle part of the skeleton 3
5,2 center of piston rod be equipped with axially through wire guide, the mistake passed through for coil 4 is radially equipped on the wall of piston rod 2
String holes II 6, the cable-through hole II 6 are connected to cable-through hole I 5 and wire guide respectively, and the coil 4 sequentially passes through cable-through hole I 5 and mistake
The conducting wire 7 worn in string holes II 6 and wire guide is connect, and the wire guide is located at one end in fuel tank 1 and is filled with sealant 8,
Electromagnetic coil combination is avoided to be in contact with fuel tank, it is not high to fuel tank inner hole roughness requirements, it is easily worked, and to coil
Sealing effect is good, safe and reliable；Without being sealed to coil, reduces seal point, reduce oil liquid and oozed out along conducting wire
Risk.
In the present embodiment, 2 outer wall of piston rod is equipped with the counterbore for mounting framework 3, and it is heavy that the skeleton 3 is fixed on
Kong Shang, convenient for assembly.
