When fixed frame 1 deflects relative to support base 2 to front side, fixed frame 1 passes through rotating bar 9, guide rod 10, first
Rack gear 11, first gear 12 drive first gear axis 13 to rotate, and the first ratchet 25 on first gear axis 13 rotates,
Then the rotation of the second ratchet 26 is driven by the first pawl 27, second ratchet 26 rotates so that the first friction dish axle 15 and thereon
Frictional disk rotation, the rotation direction on the first turntable shaft and the 4th ratchet 33 and the 4th pawl 36 allow the second friction dish axle at this time
24 rotations it is contrary, the second friction dish axle 24 and frictional disk thereon will not rotate, and phase will occur for two frictional disks
Pair rotation.When fixed frame 1 deflects relative to support base 2 to rear side, i.e., fixed frame 1 occurs reversely to revolve around rotor 4
Turn, first gear axis 13 rotates at this time, the rotation of the first ratchet 25, and the first ratchet 25 cannot drive the second spine by the first pawl 27
Wheel 26 and the first friction dish axle 15 rotate.So that fixed frame 1 is easy to reset when deflection to the left.
When rotor 4 occurs mobile relative to support base 2 to the left, i.e., fixed frame 1 is done relative to support base 2 along rotor
4 axial forward direction movements, fixed frame 1 drive second gear by gear frame 17, L shape pipe 18, the second rack gear 20, second gear 21
Axis 22 rotates, and second gear axis 22 rotates at this time, then third ratchet 32 thereon rotates and drives the 4th by third pawl 34
Ratchet 33 rotates, and the rotation of the 4th ratchet 33 drives the second friction dish axle 24 to rotate, and frictional disk will turn in the second friction dish axle 24
Dynamic, the rotation direction in the second friction dish axle 24 allows the first friction dish axle 15 to revolve with the second ratchet 26 and the second pawl 30 at this time
What is turned is contrary, and the first friction dish axle 15 and frictional disk thereon will not give birth to rotation, and opposite rotation will occur for two frictional disks
Turn.When rotor 4 moves to the right relative to support base 2, i.e., fixed frame 1 is done relative to support base 2 along the anti-of 4 axial direction of rotor
To movement, second gear axis 22 is rotated at this time, and third ratchet 32 rotates, and the rotation of third ratchet 32 will not pass through 34 band of third pawl
Dynamic 4th ratchet 33 and the second friction dish axle 24 rotate, so that i.e. sidesway to the right when being resetted after fixed frame 1 is mobile to the left
It is dynamic, the resistance very little for needing to overcome.
The fixed frame 1 relative to support base 2 side is deflected over initial position backward when, the first rack gear 11 and first gear
12 are disengaged from.Relative to support base 2, lateral deviation turns that only two frictional disks could be made more than after initial position fixed frame 1 forward
Occur opposite rotation, then such fixed frame 1 is reset to this process of initial position after lateral deviation goes to initial position backward
In, because the first rack gear 11 is not engaged with first gear 12, it will not make two frictional disks that opposite rotation, such second pressure occur
Fixed frame 1 can be reset to initial position by the energy of the deformation savings of spring 8, not will cause because the effect of frictional disk cannot make
The case where fixed frame 1 resets very well.
When movement occurs to the right for the rotor 4 more than initial position relative to support base 2, the second rack gear 20 and second
Gear 21 is disengaged from.Fixed frame 1 is mobile only more than after initial position to the left relative to support base 2, can just make two frictions
Opposite rotation occurs for disk, and such fixed frame 1 moves right beyond after initial position, then is reset to this process of initial position
In, the second rack gear 20 and second gear 21 are not on meshing state, will not make two frictional disks that opposite rotation, the first pressure occur
Fixed frame 1 can be reset to initial position by the energy of 7 deformation of spring savings, not will cause because the effect of frictional disk cannot make admittedly
Determine the case where frame 1 resets very well.
The frictional disk connected in the first friction dish axle 15 is the first frictional disk 39, and the first friction dish axle 15 drives first
Frictional disk 39 rotates, and the first frictional disk 39 is moved axially along the first friction dish axle 15, the first frictional disk 39 and first bearing seat 14
Between have the first friction pressure spring 40 covered in the first friction dish axle 15, the frictional disk that connects is in the second friction dish axle 24
Second frictional disk 41, the second friction dish axle 24 drive the rotation of the second frictional disk 41, and the second frictional disk 41 is along the second friction dish axle 24
Axial movement has the second friction pressure spring covered in the second friction dish axle 24 between the second frictional disk 41 and second bearing seat 23
42, under the action of the first friction pressure spring 40 and the second friction pressure spring 42, the first frictional disk 39 and the second frictional disk 41 are closely pasted
It closes.
When specifically used, motor is mounted on fixed frame 1 present invention, and pedestal 3 is installed on vehicle frame.Motor shakes
It is dynamic, fixed frame 1 relative to support base 2 lateral deviation turns forward when, will drive the rotation of first gear axis 13, first gear axis 13 passes through the
One ratchet 25, second ratchet 26 etc. drive the first friction dish axle 15 to rotate, and then the first frictional disk 39 rotates, the second frictional disk 41
Because the effect of the 4th ratchet 33 and the 4th pawl 36 will not be driven by the first frictional disk 39, the first frictional disk 39 and the second friction
Disk 41 relatively rotates, and friction consumption energy plays damping effect.When fixed frame 1 moves to the left relative to support base 2,
It will drive the rotation of second gear axis 22, second gear axis 22 drives the second friction dish axle by third ratchet 32 and the 4th ratchet 33
24 rotations, and then the second frictional disk 41 rotates, the first frictional disk 39 is because the effect of the second ratchet 26 and the second pawl 30 will not
It is driven by the second frictional disk 41, the first frictional disk 39 relatively rotates with the second frictional disk 41, and friction consumption energy plays and subtracts
Shake effect.
The present invention converts frictional heat for vibration by the relative friction of two frictional disks and consumes, and damping effect is obvious, vapour
In the process of moving, by the new-energy automobile damping device, the vibration reached on motor can be obvious for the vibration that vehicle frame generates for vehicle
