Description
Technical field
This utility model relates to technical field of hydraulic, is specifically related to a kind of novel hydraulic lift system.
Background technology
What engineering truck active suspension was commonly used is electrichydraulic control hydraulic suspension, it controls process and is formed closed-loop control system by sensor and controller etc., running status according to vehicle, send control command to actuator according to the control law set in good time, flowed by regulation fluid, adjusting the most locked suspension of damped coefficient or regulation bodywork height.But current active hydraulic lift system controls oil cylinder by electrical system and responds, cost is high, and reliability is poor.And there will be during the hydraulic cylinder action of traditional suspension that system pressure is high, energy consumption is big, noise is big, action is impacted and unstable and oil cylinder occurs the phenomenon of clamping stagnation in motor process, regulation cannot be made automatically according to surface conditions rapidly in the case of without electrichydraulic control.
Utility model content
The purpose of this utility model is the defect for prior art and deficiency, it is provided that a kind of simple in construction, novel hydraulic lift system reasonable in design, easy to use, it may ensure that road conditions can be responded by engineering truck timely and accurately.
For achieving the above object, the technical solution adopted in the utility model is: it comprises hydraulic cylinder, accumulator, balanced valve, servo valve, overflow valve, check valve, variable pump, oil absorption filter, fuel tank；Oil absorption filter it is provided with in fuel tank；Fuel tank is connected with variable pump through fuel sucking pipe；Variable pump outlet connects check valve；The other end of check valve connects overflow valve, servo valve；Servo valve connects hydraulic cylinder rodless cavity；Servo valve is connected with balanced valve, accumulator in turn on the big chamber in-line of hydraulic cylinder rodless cavity；Hydraulic cylinder rod chamber is connected with balanced valve, servo valve respectively；Servo valve connects fuel tank through oil return pipe；
Described servo valve is 3-position 4-way servo reversing valve, and Median Function uses y-function；
Described balanced valve is made up of check valve and main valve plug；
After using said structure, this utility model has the beneficial effect that a kind of novel hydraulic lift system described in the utility model, the response road conditions that it can be automatic accurate；When its hanging oil cylinder can automated to respond to carry out stretching motion according to road surface, fluid passes in and out accumulator, to reach to absorb the effect of impact, reduce energy consumption and noise simultaneously, and avoid hydraulic shock and cause oil cylinder malfunction, and have simple in construction, arrange rationally, the advantage such as cost of manufacture is low.

Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is further described.
Referring to shown in Fig. 1, this detailed description of the invention is provided with oil absorption filter 4 in the technical scheme is that fuel tank 5；Fuel tank 5 is connected with variable pump 6 through fuel sucking pipe；Variable pump 6 outlet connects check valve 7, to play the effect of protection pump；The other end of check valve 7 connects overflow valve 3, servo valve 8；Servo valve 8 connects hydraulic cylinder rodless cavity 9-1；Servo valve 8 is connected with balanced valve 2, accumulator 1 in turn on the big chamber in-line of hydraulic cylinder rodless cavity 9-1；Hydraulic cylinder rod chamber 9-2 is connected with balanced valve 2, servo valve 8 respectively；Servo valve 8 connects fuel tank 5 through oil return pipe；
Described servo valve 8 is 3-position 4-way servo reversing valve, and Median Function uses y-function；
Described balanced valve 2 is made up of check valve and main valve plug；
In this embodiment, variable pump 7 provides oil sources；Servo valve 8 controls hydraulic cylinder direction and speed；Accumulator 1 absorbs impact, reduces energy consumption；Balanced valve 2 prevents big chamber in-line rapid decompression from causing oil cylinder to decline；Overflow valve 3 makees relief valve and uses, and carries out overload protection；
When servo valve 8 is positioned at middle position, working connection is closed, and the piston of hydraulic cylinder 9 floats, and may move under external force, variable pump 7 not off-load (pump is in minimum injection rate state)；Balanced valve 2 prevents big chamber in-line rapid decompression to cause oil cylinder to decline；
When servo valve 8 is positioned at left position, variable pump 6 provides pressure oil through fuel tank 5, flows through check valve 7, servo valve 8, balanced valve 2, accumulator 1 enter hydraulic cylinder rodless cavity 9-1；Hydraulic oil in hydraulic cylinder rod chamber 9-2 flows to fuel tank 5 through servo valve 8；The biggest chamber in-line upward pressure is relatively low, and the main valve plug on balanced valve 2 is closed；Hydraulic cylinder 9 piston is promoted right lateral by pressure oil；When hydraulic cylinder 9 piston right lateral to right-hand member termination or walk to can not the position of right lateral again time, big chamber in-line upward pressure raises, and overflow valve 3 is opened, and pressure oil is just through the direct oil sump tank 5 of overflow valve 3；
When servo valve 8 is positioned at right position, variable pump 6 provides pressure oil through fuel tank 5, flows through check valve 7, servo valve 8 enters hydraulic cylinder rod chamber 9-2；The biggest chamber in-line upward pressure raises, and the main valve plug on balanced valve 2 is opened, and the hydraulic oil in hydraulic cylinder rodless cavity 9-1 flows to fuel tank 5 through accumulator 1, balanced valve 2, servo valve 8；Hydraulic cylinder piston is promoted left lateral by pressure oil；The big chamber in-line rapid decompression that prevents balanced valve 2 causes oil cylinder to decline (now balanced valve spool is opened, inoperative)；When hydraulic cylinder 9 piston left lateral to left end termination or walk to can not the position of left lateral again time, the oil circuit pressure of hydraulic cylinder rod chamber 9-2 raises, and overflow valve 3 is opened, and pressure oil is just through the direct oil sump tank 5 of overflow valve 3.
The above, only in order to the technical solution of the utility model to be described and unrestricted, other amendment or equivalent that the technical solution of the utility model is made by those of ordinary skill in the art, without departing from the spirit and scope of technical solutions of the utility model, all should contain in the middle of right of the present utility model.
