Specific embodiment
The present invention is described further below in conjunction with the accompanying drawings：
Referring to accompanying drawing 1, a kind of small four-wheel hydraulic-driven Multifunction outdoor Operation Van walking closed type hydraulic system includes：Fuel tank 1,
Variable pump assembly 2, flushing valve 3, left front hydraulic motor 4, right preceding hydraulic motor 5, repairing overflow valve 6, left back hydraulic motor 7, the right side
Rear hydraulic motor 8, engine 9.
Above-mentioned left front hydraulic motor 4 and the tandem of left back hydraulic motor 7 are connected, after above-mentioned right preceding hydraulic motor 5 and the right side
The series connection of hydraulic motor 8, the hydraulic motor of the above-mentioned left and right sides is connected in parallel；A, B mouthful of above-mentioned flushing valve 3 and variable pump assembly
2 A, B mouthful of corresponding connection；R mouthfuls of above-mentioned left front hydraulic motor 4 is connected with A2 mouthfuls of flushing valve 3, left front hydraulic motor 4
L mouthfuls is connected with A mouthfuls of repairing overflow valve 6；D mouthfuls of above-mentioned repairing overflow valve 6 is connected with R mouthfuls of left back hydraulic motor 7, left
L mouthfuls of rear hydraulic motor 7 is connected with B2 mouthfuls of flushing valve 3；L mouthfuls of above-mentioned right preceding hydraulic motor 5 with A1 mouthfuls of flushing valve 3 even
Connect, right first R mouthfuls of hydraulic motor 5 is connected with B mouthfuls of repairing overflow valve 6；C mouthfuls of above-mentioned repairing overflow valve 6 with the right side after hydraulic pressure
L mouthfuls of motor 8 is connected, and R mouthfuls of right rear hydraulic motor 8 is connected with B1 mouthfuls of repairing overflow valve 6；Above-mentioned repairing overflow valve 6
G mouthfuls be connected with G mouthfuls of variable pump assembly 2；Above-mentioned flushing valve 3T mouthfuls is connected with T2 mouthfuls of variable pump assembly 2；Above-mentioned change
T1 mouthfuls of amount pump assembly 2 is connected with hydraulic oil container.
When vehicle advances walks, the engine 9 starts, and variable pump assembly 2 follows rotation and hydraulic fluid port A is fuel-displaced, liquid
Force feed is by flushing valve 3 and from its A1, A2 mouthful while being given to hydraulic motor L mouthfuls before the R of left front hydraulic motor 4 mouthfuls and the right side, this two
Individual motor starts to rotate, and then hydraulic oil flows to repairing and overflows from hydraulic motor R mouthfuls before the L of left front hydraulic motor 4 mouthfuls with the right side respectively
A mouthful of valve 6 and B mouthful of stream, then again from D mouthful and C mouthfuls of repairing overflow valve 6 and meanwhile to R mouthfuls of left back hydraulic motor 7 with it is right after liquid
L mouthfuls of pressure motor 8, drives two hydraulic motors to rotate, then again from L mouthful of left back hydraulic motor 7 with right rear hydraulic motor 8
R mouthfuls of flow to flushing valve 3 B1, B2 mouthful, then flows back to B mouthfuls of variable pump assembly 2, is thusly-formed a complete loop.
When vehicle rollback is walked, the engine 9 starts, and variable pump assembly 2 follows rotation and hydraulic fluid port A is oil return
Mouthful, hydraulic fluid port B is oil-out, with each hydraulic motor, hydraulic valve bank into a loop.
Referring to Fig. 2, when vehicle turn or it is uneven wait road surface to walk when, vehicle in differential state, now
Repairing overflow valve 6 is started working, and the Fill valve 601 and overflow valve 602 in repairing overflow valve 6 carry out corresponding repairing and overflow
Stream, such as when turning round, before and after interior survey wheel speed it is slow, it is necessary to hydraulic oil it is relatively less, can be built the pressure between two hydraulic motors, reach
During certain pressure overflow valve 602 will overflow, prevent hypertonia and booster and discharge unnecessary hydraulic oil；Two, outside liquid
The speed of pressure motor it is of a relatively high, it is necessary to hydraulic pressure Chuck Steak, now Fill valve 601 will give two hydraulic motors between pipe
Road repairing prevents the oil circuit to be emptied and build the pressure problem, so as to thoroughly solve the problems, such as differential.
When vehicle traveling is on the road surface that the wheels such as ice-snow field, wet and slippery meadow easily skid, the hydraulic pressure of tandem connection
Motor can prevent front side or rear side wheel slip.
During vehicle to run, walking oil circuit in always can some high-temperature liquid force feed flow back to oil from flushing valve 3
Case, takes away partial heat, while understand some new low temperature hydraulic oil adds to hydraulic pressure from fuel tank by variable pump assembly 2
In loop, thus come to lower the temperature to closed hydraulic loop, hydraulic oil temperature is too high in preventing loop.
The present invention provides a kind of simple and reliable structure for small four-wheel hydraulic-driven Multifunction outdoor Operation Van, thoroughly
Solve when vehicle is walked on various road surfaces and encounter differential, slippage problems.
