Description
Technical field:
The utility model relates to a kind of steering gear and switching valve standard performance checkout equipment, belongs to vehicle steering valve and steering gear pick-up unit technical field.
Background technology:
Along with automobile industry develops rapidly, also more and more higher to the usability requirement of steering gear.Power steering stgear is the operating control that utilizes the power of motor car engine to carry out easily, fast turn to.The required direction dish has " portability " during running car when low speed, and " stability " is arranged during high speed, and the former requires the hand-power characteristic light, and the latter requires the hand-power characteristic heavy.But can not 100% after the present automobile power steering entrucking reach this requirement, so before the steering gear entrucking, must will carry out analog detection to steering assembly, we are referred to as the force characteristic test this detection, have only when the force characteristic test has reached design standards, think that just the switching valve force characteristic is qualified.All be to adopt hydraulic oil to test usually in the existing force characteristic process of the test.But when being to use hydraulic oil to test, can cause the steering gear cleanliness to be difficult to guarantee, and cause test experience cost height because of the expense height of hydraulic oil.
Summary of the invention:
The purpose of this utility model is: provide a kind of and replace hydraulic oil in testing process with mixed gas, finishing every test index examines switching valve and steering gear whether to reach design standards, and reduction experimental cost, when testing to solve existing use hydraulic oil, can cause the steering gear cleanliness to be difficult to guarantee, and cause the steering gear and the switching valve standard performance checkout equipment of test experience cost increase problem because of the expense height of hydraulic oil.
The utility model is to realize above-mentioned purpose by the following technical solutions:
A kind of steering gear and switching valve standard performance checkout equipment, it is made of air pressure station, electrical control cubicles, base, input media, pivoted arm, load device, displacement measuring device, it is characterized in that: base rear end is provided with the air pressure station, base one side is provided with electrical control cubicles, the base top is provided with protective window, protective window is provided with display screen, and display screen is connected with electrical control cubicles by lead; Workplace in the protective window is provided with worktable, and the left and right sides of worktable is respectively arranged with displacement measuring device and load device, and the rear end of worktable is provided with pivoted arm, on the described pivoted arm input media is housed.
The utility model advantage compared with prior art is:
This checkout equipment replaces hydraulic oil with mixed gas in testing process, finish every test index
Examine switching valve and steering gear whether to reach design standards, saved the detection cost, reduced pollution, and can well guarantee the cleanliness of surface of the work working environment, reduce the unnecessary cleaning protection of postorder, and unnecessary after sale complaint and complaint.When having avoided existing checkout equipment to use hydraulic oil to test, can cause the steering gear cleanliness to be difficult to guarantee, and cause the problem of test experience cost increase because of the expense height of hydraulic oil.This assay device structures is simple, and working stability is specially adapted to switching valve and steering gear standard performance and detects use.
Description of drawings:
Fig. 1 is the main TV structure synoptic diagram of steering gear and switching valve standard performance checkout equipment;
Fig. 2 is the side-looking structural representation of steering gear and switching valve standard performance checkout equipment.
Among the figure: 1, air pressure station, 2, electrical control cubicles, 3, base, 4, input media, 5, pivoted arm, 6, load device, 7, displacement measuring device, 8, protective window, 9, display screen, 10, worktable.
Embodiment:
This steering gear and switching valve standard performance checkout equipment are made of air pressure station 1, electrical control cubicles, base 3, input media 4, pivoted arm 5, load device 6, displacement measuring device 7, base 3 rear ends are provided with air pressure station 1, air pressure station 1 is made of supercharge pump, pressure pan, voltage stabilizer, exsiccator etc., is mainly used in stable source of the gas is provided when detecting steering gear and switching valve characteristic.Base 3 one sides are provided with electrical control cubicles 2, and base 3 tops are provided with protective window 8, to prevent in the testing process staff being caused unexpected injury.Protective window 8 is provided with display screen 9, and display screen 9 is connected with electrical control cubicles 2 by lead.Workplace in the protective window 8 is provided with worktable 10, and the left and right sides of worktable 10 is respectively arranged with displacement measuring device 7 and load device 6.Displacement measuring device 7 by servomotor, displacement transducer, can constitute by axially movable bracing frame, be used for detecting when steering gear detects axial force the displacement of tooth bar.Load device 6 by servomotor, can axially movable be configured to, be used for giving when steering gear detects axial force the tooth bar two ends to load load and use.
The rear end of worktable 10 is provided with pivoted arm 5, and input media 4 is housed on the pivoted arm 5.Input media 4 is made of servomotor, torsion bar sensor, is mainly used in the characteristic and the unloaded moment that detect switching valve and uses; Pivoted arm 5 is used to adjust the swash angle position (referring to accompanying drawing 1-2) of input media 4.
During this checkout equipment work, tooth bar axial restraint with steering gear, valve, tooth bar is not relatively moved at axial location and steering gear, valve, the input and output gas joint at air pressure station 1 is screwed into the oil inlet and outlet of steering gear, valve respectively, left-right rotation steering gear, valve input end to gas reach till the pressure of regulation, the relation between record input torque and air pressure.If the curved line relation between moment of torsion and air pressure satisfies design standards.Be that decidable steering gear valve characteristic is qualified.The main advantage of this checkout equipment is to reduce by the cycling and reutilization to gas to detect cost, and reduces the pollution of steering gear surface and working environment, reduces client's complaint not up to standard to the steering assembly surface clearness.This assay device structures is simple, and working stability is specially adapted to switching valve and steering gear standard performance and detects use.
