Description
Technical field
The invention belongs to cushion technique fields, are related specifically to a kind of damping of electric vehicles device.
Background technology
Damper is mainly used for buffering because of ground the impact vibration caused in face of vehicular impact to driver, is driven with improving
The auto parts machinery of personnel's comfort.Spring in damper plays a part of to mitigate impact, and " big energy one-shot " is become " small
Energy repeat impact ", and damper is exactly gradually to reduce " small capacity hump ".If you opened what damper had broken down
Vehicle, you can know from experience through the spring that repercussions ripple after each pit-hole, fluctuating, and damper is exactly used for inhibiting this spring
's.There is no damper to will be unable to the rebound of control spring, serious spring will be will produce when encountering rugged road surface, when excessively curved
The forfeiture of tire earth-grasping force and tracking can be caused because of the concussion above and below spring.
In the prior art, as the Chinese invention patent of Patent No. 201420299835.7 discloses, including：Damper
Seat, damper upper plunger and damping spring, the both ends of the damping spring are individually fixed in the shock absorber bearing and the damping
On device upper plunger, the lower end of the damper upper plunger is liftably plugged in the sleeve of the shock absorber bearing, the damping
The lower part of device seat is provided with shock absorber mounting board, and oil pipe mounting-positioning holes are provided on the shock absorber mounting board.This structure
The both ends of damping spring of damper be directly anchored on shock absorber bearing and damper upper plunger, once therefore this damper group
After dress, the elastic resistance of damping spring is constant, and the requirement to spring also accordingly improves, therefore there is flexible for this damper
Property difference and the not strong disadvantage of practicability.
Invention content
The present invention, which provides, a kind of to be convenient for carrying, is easy to use, suitable for the respirator of field emergency.
To achieve the goals above, the present invention adopts the following technical scheme that：
A kind of damping of electric vehicles device, including shock absorber bearing, piston rod, damping spring, baffle ring, the first mounting plate and the second installation
Plate is installed with the first mounting plate on the top of the shock absorber bearing, baffle ring is provided with the seat of shock absorber bearing；Damper
Seat is internally provided with sleeve, and the piston rod is movable to be mounted in sleeve；Is fixedly connected on the piston rod
One end of two mounting plates, the damping spring is fixedly connected on baffle ring, and the other end of damping spring is fixedly mounted on piston
On the end of bar；Further include gas-tight silo and piston cylinder cover, the sleeve connection in the shock absorber bearing has a gas-tight silo, sleeve with it is close
The junction in envelope storehouse is provided with piston cylinder cover, and the piston cylinder cover and gas-tight silo form the enclosure space of a sealing；It is described
Gas-tight silo in be filled with high pressure gas.
The damper of the present invention has dual shock absorption effect, the high pressure gas in damping spring and gas-tight silo, when damping bullet
Piston rod will act on piston cylinder cover when spring is compressed to a certain amount of, i.e., carried out to the high pressure gas in gas-tight silo further
Compression, tool will not accomplish in one move there are one cushioning effect during compressed gas, during damping effect increases not
The phenomenon that will produce moment all standing.
Further, the pressure in the gas-tight silo is 0.4 ~ 0.6MPA, and preferred pressure is 0.45MPA, such height
Body of calming the anger can also further compress, and play the effect of bumper and absorbing shock.
Further, further include cushion pad, the piston cylinder cover and barrel contacts are provided with cushion pad on one side, avoid living
Stopper rod directly liquidates with piston cylinder cover, damages piston rod or piston cylinder cover.
Further, the maximum compressibility of the damping spring is 20cm, the use specification of damping spring is defined, not
With suitable damping spring can be chosen on the electric vehicle of purposes as needed.
Further, the top of the piston rod and piston cylinder cover are at a distance of 10cm.
The advantage of the invention is that using dual shock absorption effect, with high pressure gas and damping spring as the damping factor,
Play cushioning effect first is damping spring, best in the damping effect of certain damping range internal damping spring, if but prominent
So by excessive external force, high pressure gas will play cushioning effect, and the superposition of this damping effect is submissiveer；Integral manufacturing
Simply, there is very strong practicability and usability.
