Description
Technical field:
The utility model relates to a kind of shock absorption device, specifically is a kind of inflation spring type shock absorber that is connected between fork truck actuating device and the fork truck vehicle frame.
Background technology:
At present, vehicular shock absorber generally comprises piston rod, piston, cylinder body and damping spring; One end of described piston rod is connected with automobile support, and its other end is connected with piston; Described cylinder body is enclosed within piston and piston rod outside; One end of described cylinder body is connected with automotive proplsion; Described damping spring cylinder interior and be supported on piston and cylinder body between.The running car that adopts above-mentioned bumper at not level road or wheel when the obstacle top is crossed, car body bob or vibrations occur because of self gravitation, at this moment, automobile support can drive piston and press down damping spring under the effect of car body gravity, thereby make automotive proplsion and automobile support generation relative displacement, when the automobile obstacle negotiation travels on more flat road surface, the car body vibrations are eliminated, compressed damping spring utilizes bounce to return to initial condition, the shock absorption device of said structure relies on being compressed repeatedly and rebounding of damping spring, thereby has effectively reduced the vibrations that automobile is subjected in the process of moving.Because the damping spring in the said structure bumper is only applicable to the lighter vehicle of a part of car body weight, as motor bike, C-class etc., therefore, for some heavy-dutys vehicle, as fork truck, production firm generally all can only realize cushioning effect by the diameter and the spring external diameter that increase the number of springs in the bumper or increase spring spring silk, but number of springs increase or the increase of spring spring filament diameter and spring external diameter has increased the volume of bumper.In addition, because described damping spring is to be in repeatedly compression and bounce-back state for a long time in vehicle traveling process, so damping spring was easy to because of weariness working reduction of service life.
The utility model content:
The technical problems to be solved in the utility model is, provides that a kind of volume is little, the inflation spring type shock absorber of long service life.
Technical solution of the present utility model is that a kind of inflation spring type shock absorber with following structure is provided: it comprises that the cylinder body of piston, damping spring, left end opening and an end are used for being connected with the fork truck support other end and piston bonded assembly piston rod; Described cylinder body is enclosed within piston and piston rod outside; Described piston and cylinder body bearing fit; The left end of described cylinder body is connected with a cylinder head; Described piston rod and cylinder head bearing fit; Described damping spring be enclosed within on the piston rod body of rod and two end supports between piston and cylinder head; The sidewall of the close cylinder head of described cylinder body is provided with a supplied gas and enters the through hole of cylinder interior; Be connected with a tube-shaped joint on the circumferential surface of described cylinder body; Described tube-shaped joint is connected with through hole.
After adopting above structure, compare with the prior art pressure, the utlity model has following advantage: because the utility model enters the through hole of cylinder interior at described cylinder body near being provided with a supplied gas on the sidewall of cylinder head, therefore, for the heavier vehicle of car body weight, the user can feed the gas with certain pressure by this through hole to cylinder interior, at this moment, the utility model can be under the situation that number of springs or spring spring filament diameter and spring external diameter remain unchanged, promptly guarantee to increase load-carrying capacity of the present utility model, i.e. cushioning ability by gaseous tension under the situation of original constancy of volume.In addition, effect is different separately with having only damping spring in the prior art bumper, damping spring in the utility model is be compressed gas time effect, therefore, amount of compression when it can effectively reduce damping spring work, and reduced damping spring and be in the number of times that is compressed by the limit for a long time, thereby reduced the impaired probability of damping spring, further prolonged service life of the present utility model.

Specific embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As shown in the figure, in this specific embodiment, the utility model inflation spring type shock absorber comprises that the cylinder body 8 of piston 13, damping spring 7, left end opening and an end are connected the other end and piston 13 bonded assembly piston rods 9 by axle bed 1 with fork truck support (not shown); Described cylinder body 8 is enclosed within piston 13 and piston rod 9 outsides; Described piston 13 and cylinder body 8 bearing fits; Be connected with seal ring II10 and guide ring I11 between the inner circumferential surface of the external peripheral surface of described piston 13 and described cylinder body 8; The left end of described cylinder body 8 is connected with a cylinder head 3, and its right-hand member is connected on the fork truck actuating device (not shown) by ear seat 12; Described ear seat 12 is welded on the cylinder body 8; Be connected with " O " shape seal ring 14 between the external peripheral surface of the inner circumferential surface of described cylinder body 8 and described cylinder head 3; Described piston rod 9 and cylinder head 3 bearing fits; Be connected with dust ring 2, seal ring I4 and guide ring II15 between the external peripheral surface of the inner circumferential surface of described cylinder head 3 and described piston rod 9; Described damping spring 7 be enclosed within on piston rod 9 bodies of rod and two end supports between piston 13 and cylinder head 3; The sidewall of described cylinder body 8 close cylinder heads 3 is provided with a supplied gas and enters cylinder body 8 in-to-in through holes 5; Be welded with a tube-shaped joint 6 on the circumferential surface of described cylinder body 8; Described tube-shaped joint 6 is connected with through hole 5.In this specific embodiment, the setting height(from bottom) of described ear seat 12 is higher than the setting height(from bottom) of described axle bed 1, thereby the utility model is in when static, and when promptly fork truck does not move, described damping spring 7 will keep a kind of little tension state always under the effect of fork truck car body deadweight.
Principle of work of the present utility model is: when fork truck travels at not level road or wheel when the obstacle top is crossed, the fork truck car body bob or vibrations occur because of self gravitation, at this moment, the fork truck support can drive piston 13 and press down damping spring 7 and the gas that feeds in the cylinder body under the effect of fork truck car body gravity, thereby make fork truck actuating device and fork truck support generation relative displacement, when the fork truck obstacle negotiation travels on more flat road surface, the car body vibrations are eliminated, gas in compressed damping spring 7 and the cylinder body 8 can utilize the bounce of self to return to initial condition, thereby has effectively reduced the vibrations that automobile is subjected in the process of moving.Volume is little except having for the utility model, the advantage of long service life, it also has highly versatile, promptly the user can feed the gas with certain pressure according to the weight of actual car body in cylinder body, thereby makes the utility model can adapt to different car body weight.
