Including vehicle frame, vehicle bridge and suspension frame structure connecting the two, suspension frame structure includes damper.
Damper, including housing 1, damping magnet, guiding movement are assemblied in the Moveable shock block 3 of enclosure interior and activity subtracts
The connecting rod 2 that shake block 3 is fixedly connected.Upper, middle and lower damping magnet part is disposed with along the guide direction of housing 1 order on housing 1,
Upper damping magnet part includes three the first permanent-magnetic clamps 4 of housing upper, and middle damping magnet part includes in the middle of housing two the
Two permanent-magnetic clamps 5, lower damping magnet part includes three the 3rd permanent-magnetic clamps 6 of lower housing portion, and the magnetic field of middle damping magnet part is strong
Degree is less than the magnetic field intensity of upper and lower damping magnet part, and the pole orientation of adjacent twice permanent-magnetic clamp is radial direction and magnetic pole
In the opposite direction, it is that a complete closed magnetic is constituted between one group and Moveable shock block 3 and housing 1 per the adjacent permanent-magnetic clamp of twice
Road.In other embodiments, each of upper, middle and lower damping magnet part can be arranged in parallel including about at least two
Permanent-magnetic clamp, its quantity can also be adjusted as needed.
The bottom of housing 1 is provided with base 7, the relative plane between base 7 and Moveable shock block 3 and is respectively equipped with lower fixation
Thrust magnetic pole 8 and lower mobile thrust magnetic pole 9, and for homopolar-repulsion state, this structure can prevent Moveable shock block 3 and base 7 it
Between collide and damage.The top of housing 1 is additionally provided with top cover 10, in the relative plane between top cover 10 and Moveable shock block 3
Provided with upper mobile thrust magnetic pole 11 and upper fixed thrust magnetic pole 12, homopolar-repulsion state.Connecting rod 2 subtracts including lower end with the activity
The con-rod only of shake block 3 welding manner connection and upper end are oriented to the body of rod passed by the top cover, and con-rod only is radial dimension
The disk-shaped structure consistent with the radial dimension of Moveable shock block 3, the upper activity thrust magnetic pole 11 is located at the body of rod on connecting rod 2
Periphery, and be correspondingly arranged with the upper activity thrust magnetic pole 11 and upper fixed thrust magnetic pole 12 that magnetic pole is opposite is located at the top cover
On 10, this structure can prevent from colliding and damaging between Moveable shock block 3 and top cover 10.
Rubber seal 14 is additionally provided between Moveable shock block 3 and housing 1, sealing function, Er Qieke can be not only played
To reduce frictional resistance, it is ensured that shock-absorbing capacity gives full play to.Buffer stopper is provided between base 7 and Moveable shock block 3 simultaneously
13, to prevent under fortuitous event, Moveable shock block 3 collides with base 5, cause to damage.Between top cover 9 and Moveable shock block 3
Buffer stopper 13 also is provided with, to prevent under fortuitous event, Moveable shock block 3 collides with top cover 10, causes to damage.
