Abstract
The invention belongs to hydraulic elements, particularly relates to a high-pressure large-displacement automobile power steering pump supplying oil from a rear end, which comprises a positioning pin I and II (10, 12), a front pressure plate (8), a stator (2), a rotor (4), a blade (3), a rear pressure plate (5) and a pump cover (6), wherein an annular groove (1-1) is machined at the left end surface of a large chamber of a pump body (1) of the high-pressure large-displacement automobile power steering pump supplying oil from the rear end, so that a high-pressure region is formed by the annular groove, together with the front pressure plate (8) and a seal ring (1-3) in an annular groove (1-2) of the front pressure plate; the tighter sticking effect of the front pressure plate, a rear pressure plate and the surface of the stator is achieved through high-pressure structures at two ends of the high-pressure large-displacement automobile power steering pump supplying oil from the rear end, thus the volumetric efficiency of the steering pump can be improved, the inner leakage quantity can be reduced, and energy sources can be saved; by the high-pressure structures at two ends, oil supply to the root part of a rotor groove can be increased simultaneously, the lubricating effect of the rotor groove and the end surface is improved, and the service life is prolonged.
Description
Technical field
The invention belongs to hydraulic element, the fuel-displaced high-pressure large-displacement automobile power steering pump in particularly a kind of rear end.
Background technique
At present, along with China's rapid development of economy, the heavy-duty highway transport vehicle, the market share of heavy engineering car increases year by year, this class vehicle-mounted great, road conditions are abominable, steering system often is in high temperature, high pressure conditions.The blade type steering pump of automobile of existing structure, under high temperature, high pressure operating mode since interior discharge increase, two ends of rotor face and groove root fuel feeding deficiency, lubricated insufficient and two ends of rotor face are subjected to force unbalance, make abrasion deformation in rotor end-face and rotor short time, the steering pump working pressure descends, hard steering.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, but discharge, raising volumetric efficiency in a kind of minimizing, the fuel-displaced high-pressure large-displacement automobile power steering pump in the rear end that increases the service life are provided.
The technological scheme that technical solution problem of the present invention adopts is: the fuel-displaced high-pressure large-displacement automobile power steering pump in rear end comprises locating stud one, two, preceding pressure plate, stator, rotor, blade, back pressure plate, pump cover, be characterized in an annular groove of left side processing in the big chamber of the fuel-displaced high-pressure large-displacement automobile power steering pump pump housing in the rear end, make it with preceding pressure plate and before seal ring in the pressure plate annular groove cooperate and set up the zone of high pressure.
The invention has the beneficial effects as follows: fuel-displaced high-pressure large-displacement automobile power steering pump two ends, rear end high voltage structures can make forward and backward pressure plate and the sturdy effect of stator face compacter, thereby improves the volumetric efficiency of steering pump, discharge in reducing, energy saving; But the complete symmetry balancing rotor of pressure at two ends plate both ends of the surface are stressed, prevent that the end wear of rotor is too fast; The two ends high voltage structures can strengthen the fuel delivery to the rotor root simultaneously, improves the lubrication effect of rotor and end face, increases the service life.

Embodiment
Embodiment with reference to accompanying drawing 1～3, installs axle 9 in the rear end fuel-displaced high-pressure large-displacement automobile power steering pump pump housing 1, axle 9 left end headgears dress actuation gear 11 is fixed with key and nut.Pressure plate 8, stator 2, back pressure plate 5, pump cover 6 before the left side is provided with successively in the pump housing 1 big chamber, install the connection location with locating stud 1 between preceding pressure plate 8, stator 2 and the rear fender 5, install the location with locating stud 2 12 between the pump housing 1 and the preceding pressure plate 8, be fixed with rotor 4 on the axle 9 with respect to stator 2 correspondences, radial plug-in mounting blade 3 on the rotor 4, valve 7 is equipped with in below, the pump housing 1 big chamber.An annular groove 1-1 of left side processing in the pump housing 1 big chamber, the seal ring 1-3 that makes it to reach in the preceding pressure plate annular groove 1-2 with preceding pressure plate 8 cooperates formation zone of high pressure D, forms laminated oil zone B and oil suction district C between blade 3 and stator 2 and the forward and backward pressure plate 8,5.
The working principle of the fuel-displaced high-pressure large-displacement automobile power steering pump in rear end is: engine power rotates in stator 2 by actuation gear 11 and axle 9 driving rotors 4, blade 3, with volume-variation takes place in the seal space of forward and backward pressing plate 8,5, pressure oil is discharged.Forward and backward pressure plate 8,5 forms the zone of high pressure respectively, implement pressure compensation, make between forward and backward pressure plate 8,5 and the assembly fit compacter, improve the steering pump volumetric efficiency, forward and backward pressure plate 8,5 is the groove root fuel feeding of rotor 4 by oilhole jointly, make surface of friction pair obtain sufficient lubrication, increase the service life.
Claims (1)
1. fuel-displaced high-pressure large-displacement automobile power steering pump in rear end, comprise locating stud one, two (10,12), preceding pressure plate (8), stator (2), rotor (4), blade (3), back pressure plate (5), pump cover (6), a left side processing annular groove (1-1) that it is characterized in that the big chamber of in the rear end fuel-displaced high-pressure large-displacement automobile power steering pump pump housing (1), make it with preceding pressure plate (8) and before seal ring (1-3) in the pressure plate annular groove (1-2) cooperate and set up the zone of high pressure.
