Abstract
The utility model discloses a diaphragm-type damping energy storage cylinder for handling cars. The diaphragm-type damping energy storage cylinder comprises a cylinder berrel (5) and a plunger rod. The cylinder barrel (5) and the plunger rod can move relatively. The plunger rod comprises an upper plunger rod portion (1) and a lower plunger rod portion (9), a membrane (8) is arranged on the inner wall of the lower plunger rod portion (9), and a gasket (7) is arranged between the membrane (8) and the upper plunger rod portion (1). By the membrane-type damping energy storage cylinder, parts like a frame, a connecting-rod driving mechanism, a hydraulic pressure station, a storage battery and electrical components are protected well, vibration is reduced, and impact generated from bumpy pavements is absorbed, so that goods are enabled to be more stable during handling; in addition, by utilizing the membrane-type damping energy storage cylinder, complete cars are protected well, service lives of the cars are prolonged, and comfortableness in operating of the cars is increased.
Description
Technical field
The utility model relates to carrier, relates in particular to a kind of damping of the diaphragm type for carrier accumulation of energy oil cylinder.
Background technique
In the situation that Uneven road is used carrier carrying thing, not only easily shake bad goods, and also very large to the destructiveness of car own, cause body frame structure for automotive intensity, jointed gear unit, storage battery and electrical apparatus element all to easily go wrong, and the travelling comfort of operation is not good.
As depicted in figs. 1 and 2, during 501 incoming pressures are p from pressure oil from the oil transportation mouth to cylinder barrel, plunger rod 101 is extrapolated under the oil pressure effect, backhaul under external force G effect when plunger rod 101 returns for traditional oil cylinder of prior art.
Summary of the invention
The utility model, for deficiency of the prior art, provides a kind of diaphragm type damping accumulation of energy oil cylinder that can reduce vibrations, protection vehicle body.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Diaphragm type damping accumulation of energy oil cylinder, comprise cylinder barrel and plunger rod, between cylinder barrel and plunger rod, can be movable relatively, and plunger rod comprises plunger rod top and plunger rod bottom, and the inwall of plunger rod bottom is provided with barrier film, between barrier film and plunger rod top, is provided with packing ring.
As preferably, plunger rod top is provided with gas charging valve.
As preferably, between cylinder barrel and plunger rod, be provided with dust ring.
As preferably, between cylinder barrel and plunger rod, be provided with support ring.
As preferably, between cylinder barrel and plunger rod, be provided with seal ring.
The utility model can protect the parts such as vehicle frame, jointed gear unit, hydraulic station, storage battery and electrical apparatus element greatly, makes it vibrations and reduces, and absorbs the impact produced because of Uneven road, makes goods more steady in the handling process kind.
Compare with the transmission oil cylinder, the utlity model has following some advantage: 1, the protection hydraulic station that hoists, can reduce the impact to valve body of the instantaneous pressure that produces because of vibrations, can extend the time of hydraulic electric motor moment of torsion moment reinforcement.2, protection vehicle body integral body; while with common oil cylinder, passing through road surface; car can only carry out impact-absorbing by the elastic strain of self; to vehicle frame and linkage mechanism, destroy very large; and diaphragm type damping accumulation of energy oil cylinder can absorb the impact that Uneven road brings; play the protection vehicle frame, kinematic link, the effect of the parts such as storage battery and electrical equipment.3, walking is more steady, because diaphragm type damping accumulation of energy oil cylinder can absorb the impact that Uneven road brings, avoids car moment vibrations, therefore can walk more stably when transporting goods.
In a word, by using diaphragm type damping accumulation of energy oil cylinder, can greatly protect vehicle body integral body, extend car working life, increase the travelling comfort of car operation.
The accompanying drawing explanation
The schematic diagram of the original state that Fig. 1 is the prior art oil cylinder.
The schematic diagram of the state that hoists that Fig. 2 is the prior art oil cylinder.
The schematic diagram of the original state that Fig. 3 is the utility model oil cylinder.
The schematic diagram of the state that hoists that Fig. 4 is the utility model oil cylinder.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
As shown in Figure 3 and Figure 4, the utility model comprises cylinder barrel 5, can make with cylinder barrel 5 plunger rod of relative movement, be located at dust ring 2, support ring 3, seal ring 4 between cylinder barrel 5 and plunger rod, be located at packing ring 7, the barrier film 8 of plunger rod inside, be located at the gas charging valve 6 on plunger rod top 1, gas charging valve 6 is given the interior inflation of barrier film 8.
Plunger rod comprises plunger rod top 1 and plunger rod bottom 9, and 9 inside, plunger rod bottom are provided with barrier film 8, between barrier film 8 and plunger rod top 1, is provided with packing ring 7.Form the air pressure die cavity between barrier film 8 and piston rod.
Working principle of the present utility model:
When the pressure produced as external force G is greater than P2 air pressure in barrier film: during 5 incoming pressures are p from pressure oil from the oil transportation mouth to cylinder barrel, barrier film 8 shrank inwards and then increased air pressure under the oil pressure effect before this, when barrier film 8 internal air pressures are identical with oil pressure P, barrier film 8 stops shrinking, continue input hydraulic pressure oil, then plunger rod top 1 is upwards released together with plunger rod bottom 9 and inner body, during backhaul, plunger rod top 1 and plunger rod bottom 9 backhaul under external force G effect before this, then barrier film 8 backhaul under self P2 air pressure.
When the pressure of external force G generation is less than the interior P2 air pressure of barrier film 8: working principle is similar with the traditional oil cylinder shown in Fig. 2 with Fig. 1, during 5 incoming pressures are p from pressure oil from the oil transportation mouth to cylinder barrel, plunger rod top 1 and plunger rod bottom 9 and internal component are extrapolated under the oil pressure effect, backhaul under external force G effect while returning.
Under the oil pressure environment of sealing, when external force G change to produce oil pressure P and changes, by the Volume Changes of barrier film, make under the prerequisite that plunger rod is constant in sealed volume also relative moving up and down reach corresponding balance, and then reach damping accumulation of energy effect.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
