Abstract

The utility model discloses a hydraulic jack system for a motor vehicle. The hydraulic jack system comprises a pressure rod and an oil tank. The hydraulic jack system is characterized in that a piston is connected below the pressure rod; the piston is positioned in a pump cylinder; the lower right part of the pump cylinder is connected with the oil tank through an oil-absorption one-way valve; the lower left part of the pump cylinder is connected with a cylinder barrel of a large cylinder through an oil pressure one-way valve; a large cylinder lifting plunger piston which also serves as a cylinder barrel of a small cylinder is arranged on the inner bottom part of the cylinder of the large cylinder; the large cylinder lifting plunger piston which also serves as the cylinder barrel of the small cylinder penetrates through the cylinder barrel of the large cylinder; the top end of the large cylinder lifting plunger piston which also serves as the cylinder barrel of the small cylinder partially extends out of the cylinder barrel of the large cylinder; the lower left part of the cylinder barrel of the large cylinder is connected with the oil tank through a descending stop valve; a small cylinder hollow plunger piston is arranged on the inner bottom part of large cylinder lifting plunger piston which also serves as the cylinder barrel of the small cylinder; a working oil cavity (a) is formed in the small cylinder hollow plunger piston; a working oil cavity (b) is formed out of the lower end of the small cylinder hollow plunger piston through a one-way valve; the lower left part of the working oil cavity (b) is connected with the oil tank through a one-way valve. The hydraulic jack system for the motor vehicle is reasonable in structure, and the work efficiency of the jack is improved by increasing the jacking speed of idle load.

Description

A kind of hydraulic pressure of motor vehicle jack system
Technical field
The utility model relates to a kind of hydraulic pressure of motor vehicle jack system.
Background technology
Hydraulic jack is the indispensable instrument of the power actuated vehicles such as walking machine, construction machinery and equipment, vehicle, for the lifting operation of midget plant simple maintenance.Hydraulic jack thrust output is very large, but its plunger of traditional jack is in the null process of ascent stage, and the lifting speed that its ascending velocity is in contact with it after load is equally slow, has affected like this work efficiency, makes work efficiency lower.
Summary of the invention
Thereby technical problem to be solved in the utility model is to provide a kind of rational in infrastructure, hydraulic pressure of motor vehicle jack system of improving jack work efficiency by improving unloaded lifting speed.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of hydraulic pressure of motor vehicle jack system, comprise depression bar and fuel tank, it is characterized in that: described depression bar below is connected with piston, described piston is positioned at pumping cylinder inside, described pumping cylinder lower right is connected with fuel tank by oil sucting one-way valve, described pumping cylinder lower left is connected with vat cylinder barrel by force feed check valve, described vat cylinder barrel inner bottom part is provided with the vat lift ram little cylinder cylinder barrel of holding concurrently, described vat lift ram is held concurrently, and little cylinder cylinder barrel passes vat cylinder barrel and top end part stretches out outside vat cylinder barrel, and described vat cylinder barrel lower left connects fuel tank by decline stop valve.
The described vat lift ram little cylinder cylinder barrel inner bottom part of holding concurrently is provided with little cylinder hollow plunger.
In described little cylinder hollow plunger, be provided with working oil chamber a.
Described little cylinder hollow plunger is provided with working oil chamber b by check valve outside lower end.
Described working oil chamber b lower left connects fuel tank by check valve.
The beneficial effects of the utility model are: thus rational in infrastructure, by improving unloaded lifting speed, improve jack work efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model system architecture schematic diagram.
In figure: 1-depression bar; 2-fuel tank; 3-piston; 4-pumping cylinder; 5-oil sucting one-way valve; 6-force feed check valve; 7-vat cylinder barrel; The 8-vat lift ram little cylinder cylinder barrel of holding concurrently; 9-decline stop valve; The little cylinder hollow plunger of 10-; 11-check valve.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of hydraulic pressure of motor vehicle jack system, comprise depression bar 1 and fuel tank 2, depression bar 1 below is connected with piston 3, piston 3 is positioned at pumping cylinder 4 inside, pumping cylinder 4 lower rights are connected with fuel tank 2 by oil sucting one-way valve 5, pumping cylinder 4 lower lefts are connected with vat cylinder barrel 7 by force feed check valve 6, vat cylinder barrel 7 inner bottom parts are provided with the vat lift ram little cylinder cylinder barrel 8 of holding concurrently, vat lift ram is held concurrently, and little cylinder cylinder barrel 8 passes vat cylinder barrel 7 and top end part stretches out outside vat cylinder barrel 7, and vat cylinder barrel 7 lower lefts connect fuel tanks 2 by decline stop valve 9.
Vat lift ram little cylinder cylinder barrel 8 inner bottom parts of holding concurrently are provided with little cylinder hollow plunger 10.
In little cylinder hollow plunger 10, be provided with working oil chamber a.
Little cylinder hollow plunger is provided with working oil chamber b by check valve 11 outside 10 lower ends.
Working oil chamber b lower left connects fuel tank 2 by check valve 11.
More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
