The end of said damping hole V5 and damping hole VI6 is connected with the big chamber of the hanging oil cylinder of one side respectively, and the other end is connected with the loculus of opposite side 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 damping hole V5 are connected in parallel on by triple valve 11,12 between the loculus 10 of the big chamber 1 of left hanging oil cylinder and right hanging oil cylinder on the oil circuit; Low pressure check valve IV4 and damping hole VI6 are connected in parallel on by triple valve 13,14 on the oil circuit between the big chamber 9 of the loculus 2 of left hanging oil cylinder and right hanging oil cylinder.
The utility model is one low pressure check valve low pressure to be opened valve port and a damping hole and the valve group that is unified into is connected between the big loculus of left and right sides hanging oil cylinder by oil pipe.Damping hole and low pressure check valve are connected in parallel by two tee connections.Energy storage is connected with the loculus of hanging oil cylinder and an end adaptor union of check valve group by a tee connection, and other end adaptor union is connected with the big chamber of hanging oil cylinder.The installation method of damping hole is: an end of damping hole is connected with the big chamber of oleo-pneumatic suspension cylinder, and the other end is connected with the loculus of opposite side oleo-pneumatic suspension cylinder.The installation method of low pressure check valve is: the valve port of low pressure check valve is the big chamber of oleo-pneumatic suspension cylinder dorsad, and promptly fluid can only flow to the big chamber of oleo-pneumatic suspension cylinder, and can not flow to the loculus of energy storage and opposite side suspension cylinder from the big chamber of oleo-pneumatic suspension cylinder.
The beneficial effects of the utility model are: after adopting above-mentioned connection mode, the riding comfort of vehicle obviously improves; Especially the body roll cireular frequency when travelling turning obviously reduces, so vehicle handling stability is significantly improved.Thereby can improve safety, reliability and the traveling comfort of vehicle ' greatly.
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.
