Abstract

The invention discloses an oil pressure damping device with an external oil line, which comprises an oil cylinder, a piston and the auxiliary oil line, and is characterized in that the external oil line is arranged in parallel at the end of the oil cylinder; and the external oil line is provided with a hydraulic motor 7, one end of the hydraulic motor is communicated with an oil line at the lower end of the oil cylinder through a pair of inverted one-way valves 1 and 2 arranged in parallel, and the other end of the hydraulic motor is communicated with the oil line at the lower end of the oil cylinder through a pair of inverted one-way valves 3 and 4 arranged in parallel. Based on the situation that the damping characteristic of an oil pressure vibration damper is not influenced, the oil pressure damping device well solves the problem about heat dissipation of the oil pressure vibration damper, so as to prolong the replacement period of hydraulic oil in the oil pressure vibration damper, save the cost, and recycle energy generated in the oil pressure transformation process; and the oil pressure damping device is energy-saving and environment-friendly, and strong in practicability.

Description

A kind of oil damp device with external oil circuit
Technical field
The invention 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.
Summary of the invention
Above deficiency in view of prior art the objective of the invention is, and obtains a kind of oil damp device with external oil circuit, makes it to overcome the above shortcoming of prior art.
The objective of the invention is to realize by following means:
A kind of oil damp device with external oil circuit, form 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 present invention 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 present invention has the oil damp device of external oil circuit.
Embodiment
Below in conjunction with accompanying drawing, structure of the present invention 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 present invention 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 all 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.
