Description
Technical field
The utility model belongs to cushion technique field, is related specifically to a kind of damping of electric vehicles device.
Background technique
Damper, which is mainly used for buffering, causes impact vibration to driver because ground is in face of vehicular impact, is driven with improving
The automobile parts 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 exactly is used to inhibit this spring
's.There is no damper to will be unable to the rebound of control spring, serious spring will be generated when encountering rugged road surface, when excessively curved
The forfeiture of tire road holding and tracking can be caused because of the concussion above and below spring.
In the prior art, as the Chinese utility model patent of Patent No. 201420299835.7 discloses, comprising: subtract
Shake device seat, damper upper plunger and damping spring, the both ends of the damping spring are individually fixed in the shock absorber bearing and described
On damper upper plunger, the lower end of the damper upper plunger is liftably plugged in the sleeve of the shock absorber bearing, described
The lower part of shock absorber bearing is provided with shock absorber mounting board, and oil pipe mounting-positioning holes are provided on the shock absorber mounting board.It is this
The both ends of the damping spring of the damper of structure are directly anchored on shock absorber bearing and damper upper plunger, therefore this damper one
Denier assembling after, the elastic resistance of damping spring be it is constant, the requirement to spring also correspondinglys increase, thus this damper there is
Flexibility difference and not very practical disadvantage.
Utility model content
The utility model, 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 utility model adopts the following technical solutions:
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 peace
Loading board is fixedly 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；Damping
Device seat is internally provided with sleeve, and the piston rod is movable to be mounted in sleeve；It is fixedly connected on the piston rod
One end of second mounting plate, the damping spring is fixedly connected on baffle ring, and the other end of damping spring is fixedly mounted on work
On the end of stopper rod；Further include gas-tight silo and piston cylinder cover, the sleeve connection in the shock absorber bearing has a gas-tight silo, sleeve with
The junction of gas-tight silo is provided with piston cylinder cover, and the piston cylinder cover and gas-tight silo form the enclosure space of a sealing；Institute
Filled with high pressure gas in the gas-tight silo stated.
The damper of the utility model has a dual shock absorption effect, the high pressure gas in damping spring and gas-tight silo, when subtracting
Shake spring when being compressed to a certain amount of piston rod will act on piston cylinder cover, i.e., to the high pressure gas in gas-tight silo carry out into
The compression of one step during compressed gas there is a buffer function will not accomplish in one move, and increase process in damping effect
In the phenomenon that will not generating 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.
It further, further include cushion, the piston cylinder cover and barrel contacts are provided with cushion 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
Suitable damping spring is chosen with can according to need on the electric vehicle of purposes.
Further, the top of the piston rod and piston cylinder cover are at a distance of 10cm.
The utility model has the advantage of using dual shock absorption effect, with high pressure gas and damping spring as damping because
Son, play cushioning effect first is damping spring, best in the damping effect of certain damping range internal damping spring, if but
Suddenly by excessive external force, high pressure gas will play cushioning effect, and the superposition of this damping effect is submissiveer；Whole system
Make simply, there is very strong practicability and usability.
