Abstract
The utility model discloses an oil pressure damping device with an external oil way. The oil pressure damping device is composed of an oil cylinder, a piston and an auxiliary oil way. The oil pressure damping device is characterized in that the external oil way is arranged at one end of the oil cylinder in a parallel mode, the external oil way is provided with a hydraulic motor 7, one end of the hydraulic motor is communicated with a lower end oil way of the oil cylinder through a one-way valve 1 and a one-way valve 2 which are arranged reversely in a parallel mode, and the other end of the hydraulic motor is also communicated with the lower end oil way of the oil cylinder through a one-way valve 3 and a one-way valve 4 which are arranged reversely in a parallel mode. On the basis that the damping performance of the oil pressure damping device is not affected, the heat-dissipating problem of the oil pressure damping device is well solved, and therefore the exchanging period of hydraulic oil in the oil pressure damping device is prolonged, and cost is well saved. Moreover, energy generated during the oil pressure exchanging process is recycled, energy is saved, the environment is protected and practicability is strong.
Description
Technical field
The utility model belongs to the hydraulic shock-absorption manufacturing field of equipment.
Background technique
Damping device is widely used in the various mechanical systems, and the existence of damping device must be accompanied by the loss of energy.Existing damping device substantially all is that energy loss lost in kinetic energy was changed on the market, and in addition, the oil circuit of existing damping device all is arranged in the oil cylinder, when ordinary use, be unfavorable for the hydraulic oil heat radiation, the oil temperature is high, and the replacement cycle of hydraulic oil is shorter in the oleo-gear.
The model utility content
In view of the above deficiency of prior art, the purpose of this utility model is, obtains a kind of oil damp device with external oil circuit, makes it to overcome the above shortcoming of prior art.
The purpose of this utility model is to realize by following means:
A kind of oil damp device with external oil circuit, formed by oil cylinder, piston and auxiliary oil circuit, it is characterized in that, be arranged in parallel outside oil circuit in the termination of oil cylinder, outside oil circuit has an oil hydraulic motor 7, and an end of oil hydraulic motor is communicated with the lower end oil circuit of oil cylinder by the inverted one-way valve 1 of a pair of parallel connection and 2; The other end of oil hydraulic motor also is communicated with the lower end oil circuit of oil cylinder by the inverted one-way valve 3 of a pair of parallel connection and 4.
The utility model compared with prior art, on the basis that does not influence the oleo-gear shock absorbing characteristics, well solved the heat dissipation problem of oleo-gear, thereby prolonged the replacement cycle of hydraulic oil in the oleo-gear, well saved cost, and recycle the energy of oil pressure conversion process, energy-conserving and environment-protective, practical.
Description of drawings is as follows:
Fig. 1 is the structural representation that the utlity model has the oil damp device of external oil circuit.
Embodiment
Below in conjunction with accompanying drawing, structure of the present utility model is described in further detail.
As shown in the figure, the oil damp device with external oil circuit is made up of oil cylinder, piston and auxiliary oil circuit.Be arranged in parallel outside oil circuit in the termination of oil cylinder, outside oil circuit has an oil hydraulic motor 7, and an end of oil hydraulic motor is communicated with the lower end oil circuit of oil cylinder by the inverted one-way valve 1 of a pair of parallel connection and 2; The other end of oil hydraulic motor also is communicated with the lower end oil circuit of oil cylinder by the inverted one-way valve 3 of a pair of parallel connection and 4.Oil hydraulic motor is provided with throttle valve 5 and 6 to the oil return branch road of oil cylinder.
Its working principle is:
In draw stage, the oil pressure in the rod chamber increases, and hydraulic oil drives oil hydraulic motor 7 by 6,3,10,2 successively and rotates, and gets back to rodless cavity at last.
At compression stage, the oil pressure in the rodless cavity increases, and hydraulic oil drives oil hydraulic motor 7 by 5,1,10,4 successively and rotates, and gets back to rod chamber at last.
In two processes, because the filler opening identical (all advancing from left end) of oil hydraulic motor 7 so the oil hydraulic motor rotation direction is identical, thereby is realized than stable rotation.
Oil hydraulic motor can be selected micro-hydraulic motor for use, such as the micro-hydraulic motor of YM8 type.Whole system can be made an integrated package, will significantly reduce volume like this, and saves cost more.
The utility model has well solved the heat dissipation problem of oleo-gear on the basis that does not influence the oleo-gear shock absorbing characteristics, thereby has prolonged the replacement cycle of hydraulic oil in the oleo-gear, has well saved cost.Oleo-gear has very widely in all trades and professions to be used, and adds electricity generating device and takes up room afterwards not quite, and at automobile, train can be promoted the use of on the mining car.The repacking cost is low, and income is fast, and is practical, energy-conserving and environment-protective.
