Abstract
The utility model discloses a novel oil gas suspension system. The novel oil gas suspension system mainly comprises suspension oil cylinders, a one-way valve, a damp regulating valve, a reversing valve, a locking valve, an energy accumulator, a control unit, a hydraulic oil pipe and a control circuit. When an engineering vehicle runs in a normal road surface, the reversing valve is located at a lower position, and a left suspension oil cylinder and a right suspension oil cylinder work independently; when the engineering vehicle runs in a cross-country road surface, the reversing valve is located at an upper position, and the left suspension oil cylinder and the right suspension oil cylinder work in an interconnecting mode; and when the hydraulic oil pipe used for connecting the left suspension oil cylinder and the right suspension oil cylinder is damaged, the reversing valve is enabled to be located at the lower position, and then the left suspension oil cylinder and the right suspension oil cylinder work independently. In addition, the damp of the suspension system can be adjusted by adjustment of the damp regulating valve. The novel oil gas suspension system has the advantages that running requirements of the engineering vehicle on various road surfaces can be met, damage on the hydraulic oil pipe used for connecting the left suspension oil cylinder and the right suspension oil cylinder from hydraulic impact of the system can be effectively reduced, and the vehicle can continue to run even if the hydraulic oil pipe is damaged.
Description
Technical field
The utility model relates to a kind of vehicle hydro-pneumatic suspension system, belongs to vehicle hydro pneumatic suspension control technology field, a kind of specifically particularly novel hydro-pneumatic suspension system of engineering truck of vehicle that is used for.
Background technology
At present, hydro-pneumatic suspension system is because of its superior nonlinear spring characteristic and good damping performance, and is widely used in various engineering trucks, for example fluid-type hoisting crane, mine dumping car and wheeled loading-unloading vehicle etc.
Existing hydro-pneumatic suspension system mainly is divided into two kinds: free-standing hydro-pneumatic suspension system and interconnection type hydro-pneumatic suspension system.When travelling on the average highway road surface, the damping shock absorption effect of stand alone type and interconnection type hydro-pneumatic suspension system is suitable, and the both can satisfy the vehicle ' requirement; But when travelling on more abominable cross-country road, the interconnection type hydro-pneumatic suspension system can better reduce the outer angle of roll of wheel with respect to free-standing hydro-pneumatic suspension system, and improves the operability and the travelling comfort of vehicle.The left and right sides suspension oil cylinder of interconnection type hydro-pneumatic suspension system links to each other by hydraulic oil pipe; the erratic destruction that is subjected to from the hydraulic efficiency impact of suspension oil cylinder of hydraulic oil pipe meeting; these hydraulic efficiency impact meetings make hydraulic oil pipe produce endurance failure, produce problems such as hydraulic oil leakage, pipeline rupture through regular meeting.Particularly on large engineering vehicle, the hydraulic oil pipe span that connects left and right sides suspension oil cylinder is big, and oil pipe is easier to be damaged, if hydraulic oil pipe destroys, whole vehicle can't continue to advance.
Summary of the invention
At the defective of above-mentioned hydro-pneumatic suspension system, the purpose of this utility model provides a kind of hydro-pneumatic suspension system that can realize that stand alone type and interconnection type transform mutually.When travelling on the average highway road surface, hydro-pneumatic suspension system is in free-standing mode of operation, both can satisfy the rideability of engineering truck, can reduce the impact to hydraulic oil pipe again; When travelling on abominable cross-country road, hydro-pneumatic suspension system is in the interconnection type mode of operation, can satisfy the operability and the ride comfort of vehicle.Particularly when hydraulic oil pipe is damaged, can make suspension system be in free-standing mode of operation, make vehicle continue to travel.
The described novel hydro-pneumatic suspension system that the utility model provides mainly comprises suspension oil cylinder, check valve, damping control cock, change-over valve, detent valve, energy storage, control unit, hydraulic oil pipe and control path.Wherein, check valve is in parallel with dash pot valve, and an end links to each other with the rod chamber of suspension oil cylinder, and the other end links to each other with change-over valve; The other end of change-over valve divides two-way, and one the tunnel links to each other with detent valve with energy storage, and another road links to each other with the detent valve of opposite side by hydraulic oil pipe; Detent valve links to each other with the rodless cavity of suspension oil cylinder; Control unit links to each other with detent valve with change-over valve by control path.
Preferential, described check valve, damping control cock, change-over valve are formed an integrated dispensing unit.
Preferential, described integrated dispensing unit does not directly link to each other with energy storage with the rod chamber of hydraulic ram by any hydraulic oil pipe.
Preferential, described change-over valve is the two-position three way electromagnetic ball valve.
Preferential, described detent valve is the bi-bit bi-pass electromagnetic ball valve.
Preferential, described damping control cock is adjustable flow regulating valve.
Novel hydro-pneumatic suspension system described in the utility model can be used for the operation of travelling of various engineering trucks on various road surfaces.When travelling operation on normal highway, it is the next that control unit is in change-over valve by control path, and this moment, left and right sides suspension oil cylinder was in free-standing mode of operation; When travelling operation on abominable cross-country road, it is upper that control unit is in change-over valve by control path, and this moment, left and right sides suspension oil cylinder was in the interconnection type mode of operation; When the hydraulic oil pipe that connects left and right sides suspension oil cylinder was damaged, it was the next also can change-over valve to be in by control unit, makes left and right sides suspension oil cylinder be in free-standing mode of operation.In addition, can make the damping shock absorption effect of suspension system can satisfy the various operating conditions that travel by adjusting the damping control cock.If make hydro-pneumatic suspension system be in rigid state, it is upper detent valve to be in by control unit, and the rodless cavity of suspension oil cylinder and energy storage are disconnected.
Advantage of the present utility model and beneficial effect: the utility model combines the advantage of existing stand alone type and interconnection type hydro-pneumatic suspension system, not only can satisfy the travel requirement of operation of the various ground-surfaces of engineering truck, but also can actv. reduce and reduce hydraulic efficiency impact that suspension system produces to being connected the destruction of left and right sides suspension oil cylinder hydraulic oil pipe, prolong its service life.In addition,, also can make vehicle continue the operation of travelling, improve the rideability of vehicle even when hydraulic oil pipe is destroyed.
