The utility model aims to provide a double check valve connection type hydro-pneumatic suspension system for improving the driving smoothness and steering stability of the special vehicle. The utility model has the technical proposal that the system comprises one-way valves, suspension oil cylinders and accumulators, and is characterized in that a one-way valve group composed of a low pressure one-way valve III (3) and a high pressure one-way valve V (5) is connected between a big cavity (1) of the left suspension oil cylinder and a small cavity (10) of the right suspension oil cylinder by an oil pipe; and the other one-way valve group composed of a low pressure one-way valve IV (4) and a high pressure one-way valve VI (6) is connected between a small cavity (2) of the left suspension oil cylinder and a big cavity (9) of the right suspension oil cylinder by an oil pipe; and the accumulator I (7) and the accumulator II (8) are respectively communicated with the small cavity of the suspension oil cylinder on one side and the one-way valve group on the other side by tee pipe joints.
Description
Technical field
The utility model relates to a kind of oleo-pneumatic suspension system that improves the novel connection mode of vehicle ' ride comfort and road-holding property, is specially adapted to the large special vehicle operation.
Background technology
At present, the connection mode of oleo-pneumatic suspension system mainly is divided into two classes: not merely vertical oil-gas suspension connection mode and communication type oleo-pneumatic suspension system connection mode.The rigidity transfer characteristics of communication type oleo-pneumatic suspension system is very favorable to the ride comfort that improves vehicle ', but the turning efficiency for vehicle is disadvantageous, in the turn inside diameter process, the vehicle body stable state angle of roll of this connection mode is bigger than vertical oil-gas suspension not merely.Yet,, be disadvantageous to the riding comfort of vehicle though not merely the vertical oil-gas suspension is favourable to improving vehicle handling stability.This patent is a kind of novel oleo-pneumatic suspension system that is proposed under the prerequisite of comprehensive both advantages.
Summary of the invention
The purpose of this utility model is that a kind of double check valve interconnection system oleo-pneumatic suspension system that improves the riding comfort and the road-holding property of special vehicle will be provided.
Above-mentioned purpose of the present utility model is achieved in that accompanying drawings is as follows:
A kind of double check valve interconnection system oleo-pneumatic suspension system is made up of check valve, hanging oil cylinder and energy storage, and the check valve group of a low pressure check valve III3 and high pressure check valve V5 being formed with oil pipe is connected between the loculus 10 of the big chamber 1 of left hanging oil cylinder and right hanging oil cylinder; The check valve group of another low pressure check valve IV4 and high pressure check valve VI6 being formed with oil pipe is connected between the big chamber 9 of the loculus 2 of left hanging oil cylinder and right hanging oil cylinder again; Energy storage I7 and energy storage II8 are communicated with the loculus of the hanging oil cylinder of one side and the check valve group of opposite side by tee connection respectively.
The valve port of said high pressure check valve V5 and high pressure check valve VI6 points to the big chamber 1 of left hanging oil cylinder and the big chamber 9 of right hanging oil cylinder respectively; The valve port of low pressure check valve III3 and low pressure check valve IV4 is the big chamber 1 of left hanging oil cylinder and the big chamber 9 of right hanging oil cylinder dorsad respectively.
Said low pressure check valve III3 and high pressure check valve V5 are connected in parallel between the loculus 10 of the big chamber 1 of left hanging oil cylinder and right hanging oil cylinder; Low pressure check valve IV4 and high pressure check valve VI6 are connected in parallel between the big chamber 9 of the loculus 2 of left hanging oil cylinder and right hanging oil cylinder.
Beneficial effect: after adopting above-mentioned connection mode, the riding comfort of vehicle obviously improves; Especially the vehicle roll angle when travelling turning obviously reduces, so vehicle handling stability is significantly improved.Thereby can improve safety, reliability and the traveling comfort of vehicle ' greatly.

The specific embodiment
Further specify particular content of the present utility model below in conjunction with the accompanying drawing illustrated embodiment.
On the basis of existing communication type oleo-pneumatic suspension system connection mode (consulting Fig. 1), on the connecting line between the loculus 10 of big chamber 1 of left hanging oil cylinder and right hanging oil cylinder, the valve group that a pair of high pressure check valve V5 in parallel and low pressure check valve III3 or high pressure check valve and low pressure check valve are formed.High pressure check valve V5 and low pressure check valve III3 are connected in parallel by two tee connections 11,12.Energy storage I7 is connected with adaptor union 12 with the loculus 10 of right hanging oil cylinder by a tee connection 16.The installation method of high pressure check valve V5 is: the valve port of high pressure check valve IV points to the big chamber 1 of left hanging oil cylinder, and promptly fluid can only flow to the loculus 10 of energy storage I7 and right hanging oil cylinder from the big chamber 1 of left hanging oil cylinder.The installation method of low pressure check valve III3 is: the valve port of low pressure check valve III3 is the big chamber 1 of left hanging oil cylinder dorsad, be the big chamber 1 that fluid can only flow to left hanging oil cylinder, and can not flow to the loculus 10 of energy storage I7 and right hanging oil cylinder from the big chamber 1 of left hanging oil cylinder.
On the connecting line between the loculus 2 of big chamber 9 of right hanging oil cylinder and left hanging oil cylinder, the valve group that a pair of high pressure check valve VI6 in parallel and low pressure check valve IV4 or high pressure check valve and low pressure check valve are formed.High pressure check valve VI6 and low pressure check valve IV4 are connected in parallel by two tee connections 13,14.Energy storage II8 is connected with adaptor union 13 with the loculus 2 of left hanging oil cylinder by a tee connection 15.The installation method of high pressure check valve VI6 is: the valve port of high pressure check valve VI6 points to the big chamber 9 of right oleo-pneumatic suspension cylinder, and promptly fluid can only flow to the loculus 2 of energy storage II8 and left hanging oil cylinder from the big chamber 9 of right hanging oil cylinder.The installation method of low pressure check valve IV4 is: the valve port of low pressure check valve IV4 is the big chamber 9 of right hanging oil cylinder dorsad, and promptly fluid can only flow to the big chamber 9 of right hanging oil cylinder, and can not flow to the loculus 2 of energy storage II8 and left hanging oil cylinder from the big chamber 9 of right hanging oil cylinder.
Fig. 3 and Fig. 4 be adopt three kinds of connection modes the vehicle of oleo-pneumatic suspension system in the turning process, during vehicle roll angle comparison diagram and ride comfort are analyzed, the situation of change comparison diagram of vehicle roll angle.More can improve the riding comfort and the road-holding property of vehicle from the novel as can be seen oleo-pneumatic suspension of figure system.
