The slide-bar type liquid-level height acquisition instrument is simple in structure, rapid and efficient, is used for providing the accuracy detection for signals of the liquid level, and meanwhile improves efficiency of the detection of the liquid level.
Description
Technical field
The utility model relates to the sensing detection technology, relates in particular to the detection of gear reducer lube liquid level.
Background technology
The bottom of speed reduction unit needs to add a certain amount of lubricating oil, is used for the gear of running is realized effectively lubricating.Along with the continuous operation of speed reduction unit, lubricating oil can constantly run off.So the liquid level that sensor is gathered lubricating oil is set, seems necessary.Using for reference widely used float-ball type liquid level sensor in the automotive field, is a kind of effective scheme.By the pointer of ball float drive swept resistance under the effect that oil mass changes, change the resistance of swept resistance, the electric current that flows through the oil mass indicating gauge is changed, the pointer of indicating gauge is done corresponding mobile at index dial, reach the purpose of indicating oil mass.Because swept resistance is installed in the speed reduction unit, be subjected to the restriction in speed reduction unit internal height and space, the swept resistance pointer is very short, the distance of sliding is generally at 20-30mm, circle surplus the coil of swept resistance also only has tens to 100, therefore certain corresponding mobile coil turn of oil mass variation is less, and resolution is very low, and the oil meter pointing accuracy is scholar 10%.
The utility model content
The utility model provides a kind of slide bar type liquid level Acquisition Instrument of simple in structure, quickness and high efficiency, is used for providing liquid level signal is accurately detected, and improves the efficient that liquid level detects simultaneously.
For realizing above-mentioned purpose, the technical solution adopted in the utility model is that a kind of slide bar type liquid level Acquisition Instrument comprises: shell, coil, its two formed resistor disc; The pointer of ball float, slide bar and swept resistance is the integral body of an interlock, is installed in speed reduction unit; Described resistor disc is installed in outside the speed reduction unit; The length of described resistor disc is 100mm, and the coil turn that is wound on the described shell is 200 circles, and described shell is arc.
Compare with conventional art, the utility model increases length with the described resistor disc of swept resistance, increase the number of turn of coil, the swept resistance sheet is fixed on the arc shell that designs, the pointer of swept resistance is lengthened, increase sweep radius, identical oil mass is changed in the mobile distance of resistor disc strengthen, reach the purpose that improves resolution.Simultaneously, for not being subjected to the restriction of speed reduction unit inner space, swept resistance and shell are installed in outside the speed reduction unit.
Owing to adopt such scheme, the precision that sensor detects can improve greatly, with the supporting use of digital oil mass indicating gauge, can make the oil mass pointing accuracy reach scholar 1%.And simple in structure, easy to install and use, need not do any change to former car speed reduction unit.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model slide bar type liquid level Acquisition Instrument.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model, the similar elements label represents similar elements in the accompanying drawing.As mentioned above, the utility model provides a kind of slide bar type liquid level Acquisition Instrument, makes its simple in structure and easy operating and use more.
As shown in Figure 1, among the embodiment.3 is shell, and 4 is coil, its two formed resistor disc.Ball float 1, slide bar 2 are the integral body of an interlock with the pointer 5 of swept resistance, be installed in speed reduction unit, the swept resistance pointer 5 that has lengthened is installed in outside the speed reduction unit, and the upper angle that the angle of ball float 1 upper and lower movement and swept resistance pointer move at swept resistance sheet 1 is linear.The variation of oil mass in the speed reduction unit, ball float 1 is subjected on the buoyancy function, float down, drive slide bar 2, swept resistance pointer 5 is done corresponding mobile at the wire-wound resistor disc, thereby change the voltage on the swept resistance pointer 5, because the variation oil mass of each circle coil correspondence significantly reduces than traditional sensor, be that certain oil mass variation makes the pointer of swept resistance increase greatly at the sensor that the mobile coil ratio of wire-wound resistance uses now, and the magnitude of voltage that every circle coil detects when being contacted by the pointer of swept resistance is exactly the check point that we need, check point is many, resolution is just high, so accuracy of detection also just obtains improving.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection domain of the present utility model to any simple modification, equivalent variations and modification that above embodiment does.
