Embodiment
Single hydraulic fluid port steering pump working principle of the present invention is can realize flow control principle and pressure control principle on metering pump working principle basis.Metering pump working principle is to be embodied as steering system to provide pressure versus flow, and pressure versus flow is directly proportional, and the pressure of output is relevant with load, and the flow of output is directly proportional to rotating speed, and rotating speed more high flow capacity is larger.Flow control principle is that the flow that guarantees steering pump input redirect system is tending towards constant.
Flow control principle: produce pressure drop and form pressure reduction when pumping oil pocket fluid by flow control damping hole, larger by the larger pressure reduction of damping hole flow, and damping hole two ends fluid acts directly on respectively the two ends of flow control valve, when pressure reduction has been broken flow control valve state of equilibrium, valve has overcome spring force and has started mobile under the effect of pressure reduction, using oil pocket communicates with oil spilling mouth, fuel-displaced cavity segment flow overflows through flow-off, make to be tending towards constant by the output flow of oil outlet input redirect system, realize flow control.If engine speed improves output flow and increases, control valve displacement amount has added overflow openings increase, and overfall flooded traffic just increases, thereby has stablized output flow, has guaranteed that driver sails and handles feel and Security at high-speed downstream.
Pressure control principle: when induced pressure reaches the cracking pressure that boost pump is set, during pressure maximum, cone valve is opened, and realizes overflow, defines system maximum pressure.
Single hydraulic fluid port steering pump structure of the present invention as depicted in figs. 1 and 2, the pump housing 25 tops are provided with filler opening 31, in the pump housing 25, be provided with oil-feed side plate 26 and fuel-displaced side plate 18, axle 1 runs through oil-feed side plate 26 and fuel-displaced side plate 18 centers of being installed on, locating stud 28 runs through oil-feed side plate 26, stator 24, fuel-displaced side plate 18 to be connected on the pump housing 25, has limited rotary freedom.Gear 2 and bearing 5 are installed in axle 1 one end, and gear 2 carrying pump input power transmission, install back-up ring 4 between gear 2 and bearing 5.In the pump housing 25, be provided with guiding valve 7, guiding valve 7 one end are provided with spring 12, guiding valve 7 inside are provided with cone valve 8, between cone valve 8 one end and guiding valve 7, be provided with spring 9, guiding valve 7 has one end of spring 12 to connect delivery connection 17, fuel-displaced 17 one end that connect are connected with pump housing valve opening, and connection part seals by combination mat 16, and the other end is connected with fuel-displaced pipeline.The pump housing 25 one end are provided with pump cover 20, fixing by Steel Cable Baffle Ring 15 between pump cover 20 and the pump housing 25, mounting spring 19 between fuel-displaced side plate 18 and pump cover 20, and spring 19 is pressed in fuel-displaced side plate 18 end faces and has limited axial position and played again floating effect.Rotor 22 is arranged in stator 24 endoporus, under the driving of axle 1, rotate, make to be mounted in it flat the dishing out of blade 23 in rotor 22 slotted eyes, blade 23 forms closed containing cavity, and by the oily fenestra on oil-feed side plate 26, fluid is sucked with stator 24 negative cambers, oil-feed side plate 26, fuel-displaced side plate 18.When rotor 22 forwards stator 24 negative cambers to, fall journey part, because cavity volume reduces, compressed fluid flows out by the fuel-displaced fenestra of fuel-displaced side plate 18, and the fluid of outflow is controlled flow by damping hole, through delivery connection 17, enters steering system.Flow into flow control guiding valve 7 has one end of spring 12 simultaneously.Part fluid enters flow control relief valve without spring 12 ends.Because the flow of the damping hole of flowing through can produce pressure reduction, when pressure reduction is more than or equal to spring 12 power, the balance of guiding valve 7 is broken, and guiding valve 7 produces mobile, using oil pocket communicates with oil spilling mouth, fuel-displaced cavity segment flow overflows through flow-off, makes output flow be tending towards constant, realizes flow control principle.Act on the fluid of spring 9 ends, by conical valve base upward pressure damping hole, act on cone valve 8, when system pressure is more than or equal to spring 9 pre-set up several, cone valve 8 is opened and overflow, has limited the maximum pressure of system, realizes pressure control principle.Spring 19 guarantees that fuel-displaced side plate 18, stator 32 can closely be connected, and guarantee that design performance is achieved.Pack the bearing 5 of the pump housing 25 and centering and the transmission accuracy of composite bearing 21 assurance axles 1 into, realize performance accuracy.On axle 1, be positioned at oil-feed side plate 26 1 side mounting framework oil sealings 6, outside framework oil seal 6 sealing functions are for guaranteeing that air is not inhaled into and oil pocket fluid does not leak.
The present invention is described by embodiment, and those skilled in the art know, without departing from the spirit and scope of the present invention, can carry out various changes or equivalence replacement to these features and embodiment.In addition, under instruction of the present invention, can modify to adapt to concrete situation and material and can not depart from the spirit and scope of the present invention these features and embodiment.Therefore, the present invention is not subject to the restriction of specific embodiment disclosed herein, and the embodiment within the scope of all the application's of falling into claim belongs to protection scope of the present invention.
