Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of power steering gear performance test hydraulic pressure installation described in the utility model, comprise Oil pump electrical machinery group 2, on the filler opening of Oil pump electrical machinery group 2, by oil pipe, is connected with oil absorption filter 1, and oil absorption filter 1 connects fuel tank by oil pipe.Be connected with one-way valve 3 and pressure piping filter 5 by oil pipe on the oil outlet of Oil pump electrical machinery group 2, the outlet oil pipe of pressure piping filter 5 is punished into four branch roads at the A point: first branch road is that relief valve 4 is housed, and the branch road be connected with fuel tank; Second branch road is divided into again two little branch roads after reduction valve 6 arrives the D point, one through one-way valve 3, pressure gauge 10 be connected to double-action power cylinder 9 cavity of resorptions, another each and every one one-way valve 3 is connected the power loop of double-action power cylinder 9 epicoeles formations with pressure gauge 10, and be connected with the input end of power steering gear 12; The 3rd branch road is the oil supply loop formed through throttle valve 7, flow detector 8, pressure gauge 10 and double-action servo-cylinder, and is connected with power steering gear 12; The 4th the branch road load circuit that (two branch road principles are identical) is connected with the C point after the B point is divided into two branch roads after reduction valve 6, C point place is divided into again two little branch roads, ramuscule route one-way valve 3, relief valve 4 and a pressure gauge 10 form, and with the rod chamber of double-action resistance oil cylinder, are connected; Another ramuscule route one-way valve 3, relief valve 4 and pressure gauge 10 form, and with the rodless cavity of two-way cylinder, are connected; Be furnished with air-strainer 16 and level meter 17 in described fuel tank.One side of described power steering gear 12 is equipped with double-action power cylinder 9, and swing arm and double-action power-assisted oil cylinder 1 and the first double-action resistance oil cylinder 14, second double-action resistance oil cylinder 15 piston rods are connected.
When Oil pump electrical machinery group 2 starts; fluid is sucked out in fuel tank through oil absorption filter 1; through the A point place in one-way valve 3 and pressure piping filter 5 arrival loops, the effect of pressure piping filter 5 is turbidity test of the whole oil hydraulic circuit oil product of filter cleaning, protects each control valve normal operation.The punishment of A point has four branch roads, and one of them branch road is the branch road that relief valve 4 is housed, and relief valve 4 the effect here is the maximum pressure of protection whole system, and its force value can be by being monitored by pressure gauge 10.Other three branch roads at A point place are input branch road, the fuel feeding branch road that leads to power steering gear 12 that leads to double-action power cylinder 9 and the load branch that leads to the first double-action resistance oil cylinder 14 and the second double-action resistance oil cylinder 15.The oil that leads to double-action power cylinder 9 arrives the D point through reduction valve 6 and is divided into again two little branch roads, one through one-way valve 3, pressure gauge 10 connects double-action power cylinder 9 cavity of resorptions, another is with crossing one-way valve 3, pressure gauge 10 connects double-action power cylinder 9 epicoeles, lead to the oil of power steering gear 12 through throttle valve 7, enter into power steering gear 12 the insides after flow detector 8, by commutator servo-cylinder hydraulic fluid port, after pressure gauge 10, be connected on double-action power-assisted oil cylinder 1 again, the effect of throttle valve 77 has two, one is to adjust the flow that enters power steering gear 12 fluid, its flow value is by flow detector 8 monitoring, the another one effect is to make the inlet of throttle valve 7 produce all the time a back pressure, this back pressure can make fluid enter into the load branch of two-way cylinder by reduction valve 6, reduction valve 6 easily, swimmingly and two load branch of ordering through B on.The effect of reduction valve 6 and reduction valve 6 is that the fluid on A point loop is drawn to a part to load circuit, does not affect again the normal pressure on the commutator oil supply loop simultaneously.The outlet pressure of reduction valve 6 is set as 1~2Mpa(and is greater than one-way valve 3 cracking pressures), through reduction valve 6, fluid out is divided into two branch roads (two branch road same principle) after arriving B point place, branch road arrives C point place and is divided into again two little branch roads, and a ramuscule road is connected with the rod chamber of the first double-action resistance oil cylinder 14 through one-way valve 3, relief valve 4 and pressure gauge 10; Another ramuscule road is connected with the rodless cavity of the second double-action resistance oil cylinder 15 through one-way valve 3, relief valve 4 and pressure gauge 10.
When performance test starts, at first one-way valve 3 is opened, one-way valve 3 closes double-action power cylinder 9 cavity of resorptions generation high pressure moves upward cylinder block, and this high pressure is detected by pressure gauge 10; When cylinder body moves upward to limit switch, one-way valve 3 closes, one-way valve 3 is opened double-action power cylinder 9 epicoeles generation high pressure moves downward cylinder block, and this high pressure is detected by pressure gauge 10; When cylinder body moves downward limit switch, oil cylinder turns to again.Due to the cylinder block surface Machining tooth bar, when cylinder body pumps, drive the commutator running.During power steering gear 12 running, oil through throttle valve 7, flow detector 8 enters power steering gear 12, oil is at the interior generation high pressure of power steering gear 12, at access double-action power-assisted oil cylinder 1 after pressure gauge 10, make 1 side-to-side movement of double-action power-assisted oil cylinder drive power steering gear 12 output swing arms 13 and turn to.The high pressure of power steering gear 12 interior generations is detected by pressure gauge 10.When commutator output swing arm 13 turns to, double-action resistance oil cylinder, double-action resistance oil cylinder produce resistance to keep turning to swing arm 13 steadily to commutate simultaneously, whether the force value by monitoring pressure table 10, pressure gauge 10 and pressure gauge 10 (two pressure gauges 10 should have a table show value and pressure gauge 10 show values to reach the highest simultaneously, and two pressure gauges 10 should be identical value while reaching the highest) is qualified conveniently to monitor power steering gear 12 performances.Double-action power cylinder 9 has two effects here, and first effect is to control the direction that power steering gear 12 rotates, and second effect is to control the frequency that power steering gear 12 rotates.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
