Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the utility model partial structural diagram.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：Such as Fig. 1 and Fig. 2 institutes
Show, a kind of damper automatically adjusted, including cylinder body 1 and piston rod 43, interior slide of the cylinder body 1 are provided with first piston 2, second work
The piston 4 of plug 3 and third, the piston rod 43 are connected with third piston 4, and the first piston 2 is lived by trace 22 and the second
Plug 3 is connected, and the piston 4 of first piston 2 and third is respectively arranged with the damping hole 42 of first damping hole 23 and third, on the second piston 3
It is provided with second through hole 31, on the same line, third piston 4 is set in the axle center of the second passage 31 and third damping hole 42
The third passage 41 is equipped with, the second piston 3 is provided with some guide rods 7, and the guide rod 7 passes through third piston 4 and end
Spacing termination 71 is provided with, the overcoat of guide rod 7 is provided with pressure-bearing spring 8, permanent magnetic disk is fixedly installed on the second piston 3
Body 5, third piston 4 are fixedly installed electromagnetism disk body 6, and the electromagnetism disk body 6 produces permanent magnetic disk described in magnetic field suction after being powered
Body 5 is close.
The second piston 3 is provided with second notch 32, and third piston 4 is provided with third and is provided with the third notch 44, institute
The both ends for stating pressure-bearing spring 8 are respectively arranged in the second notch 32 and third notch 44.
Sealing ring 80 is provided with the second piston 3, the sealing ring 80 surrounds the second notch 32 and the permanent magnetic disk
Body 5.
Divided in the cylinder body 1 by the first piston 2, the piston 4 of second piston 3 and third for four cavitys, respectively the first cavity
11st, the second cavity 12, the 3rd cavity 13 and the 4th cavity 14, the first damping hole 23 connect first cavity 11 and described
Two cavitys 12, the second passage 31 connect second cavity 12 and the 3rd cavity 13, and third passage 41 connects
3rd cavity 13 and the 4th cavity 14.
The present apparatus disconnects the circuit of electromagnetism disk body 6, so as to keep second to live when vehicle is exercised on stable road surface
The piston 4 of plug 3 and third is disconnected from each other, so produces space between the two, and this space is exactly the 3rd cavity 13, then in second passage
31 and third in the presence of passage 41, have just connected the second cavity 12, the 3rd cavity 13 and the 4th cavity 14.Now, only first
Piston 2 plays damping action, and damping force is simultaneously little, avoids damper from hindering spring works.
When vehicle will exercise the road surface jolted, the circuit of electromagnetism disk body 6 is switched on, makes its energization, so, just
It can make it that the piston 4 of second piston 3 and third is adjacent to each other.Because second piston 3 is also connected with first piston 2, and resistance is provided with first piston 2
Buddhist nun hole, so the amount of movement of second piston 3 is less, the amount of movement of the third piston 4 is big.Finally the piston 4 of second piston 3 and third is mutually affixed
Close, also, because sealing ring 80 acts on, ensure that the airtight effect inside sealing ring 80, that is, air can not be from the third ventilation
The leakage of the gap on hole 41 and the periphery of guide rod 7 is walked.So now exactly the third piston 4 and first piston 2 produce damping action simultaneously.This
Sample is set, and damping force just becomes greatly, avoids spring from recovering too fast, so as to cause the bounce of vehicle.
The present apparatus is in this way, enable to user to be voluntarily adjusted according to the road conditions of reality and personal feeling, just
Just it is quick.And because regulation is that user is voluntarily adjusted, therefore be not in the situation generation of mistuning.
The scope of protection of the utility model includes but is not limited to embodiment of above, and the scope of protection of the utility model is to weigh
Sharp claim is defined, and any replacement being readily apparent that to those skilled in the art that this technology is made, deformation, improvement are each fallen within
The scope of protection of the utility model.
The utility model provides a kind of technical scheme of the damper automatically adjusted, can be according to the actual demand of user
Regulation damping, so as to suitable for various road environments, provide comfortable take for user and feel.
