Description
Technical field
The utility model relates to the low pressure oil way system in the oil supply system for vehicle, refers to especially a kind of fuel-quantity transducer device.
Background technology
Fuel-quantity transducer generally is installed in the vehicle fuel tank, by induction installation, the liquid level in the fuel tank is changed, and is converted to variable-resistance resistance change, thereby is converted into the device of the variation of electric signal.Using the most general fuel-quantity transducer just at present is float+wire resistor formula sensor, and its structure is that wire resistor is connected with float, drives wire resistor by float and changes, to realize the effect of induction fuel tank liquid level.
The fuel-quantity transducer device that generally uses at present, because rheostat adopts the Wound-rotor type variable resistor, it mostly is manual coiling or semi-mechanization coiling, be subjected to the restriction of manufacturing process etc., the number of turn, coil-span, the resistance welded of coiling, and the key parameter such as resistance wire diameter is difficult to control cause the problems such as its in use resistive conductor ablation, short circuit, wearing and tearing be inhomogeneous to take place frequently, generally only be 100,000 times～200,000 times serviceable life, and the problems referred to above can't be properly settled always.
Under this impact, the electric signal output accuracy of the existing survey sensor device that uses is not high, can accurately not monitor oil mass and oil mass situation of change in the fuel tank.
The utility model content
The purpose of this utility model is by the improvement to fuel-quantity transducer, thereby the electric current of realizing electrical signal accurately changes, and monitors accurately, reliably the interior fr of fuel tank and the situation of change of amount of fuel.
Another purpose of the present utility model is to solve existing fuel-quantity transducer short problem in serviceable life.
The utility model is achieved through the following technical solutions:
A kind of fuel-quantity transducer device includes electrical signal, base plate, sensor, connecting rod and float; Described sensor includes sensor shaft, rheostat carrier, rheostat and probe; Described float is connected by the probe of connecting rod with sensor, and described sensor shaft, rheostat carrier, rheostat and probe are connected successively, and described sensor shaft is fixed with base plate, electrical signal connecting sensor shaft.
Described base plate is for fixing on the fuel tank top inner wall.
Rheostat in the described sensor is the thick film resistor type rheostat.
The beneficial effect that the utility model is compared with prior art is:
1, under identical principle, structure has been carried out innovation, invention, this novel structure, succinct, and can effectively solve existing fuel-quantity transducer life-span weak point, poor reliability, the problem that permanance is low.
2, adopt the thick film resistor type rheostat, its thick-film resistor is printed on the rheostat carrier by computer control, and even thickness is controlled, and resistance evenly distributes, and thick-film resistor can be realized serviceable life 1,000,000 times because its material behavior makes it more wear-resistant.

Embodiment
The below describes embodiment of the present utility model in detail, and the example of described embodiment is shown in the drawings, and wherein identical or similar label represents identical or similar element or the element with identical or similar functions from start to finish.Be exemplary below by the embodiment that is described with reference to the drawings, only be used for explaining the utility model, and can not be interpreted as restriction of the present utility model.
Fuel-quantity transducer, changes the liquid level in the fuel tank by induction installation for being installed in the vehicle fuel tank, is converted to variable-resistance resistance change, thereby is converted into the device of the variation of electric signal.
A kind of fuel-quantity transducer device includes electrical signal 1, base plate 2, sensor, connecting rod 7 and float 8; Described sensor includes sensor shaft 3, rheostat carrier 4, rheostat 5 and probe 6; Described float 8 is connected by the probe 6 of connecting rod 7 with sensor, and described sensor shaft 3, rheostat carrier 4, rheostat 5 and probe 6 are connected successively, and described sensor shaft 3 usefulness base plates 2 are fixing, electrical signal 1 connecting sensor shaft 3.Described base plate 2 is fixed on fuel tank 9 top inner wall; Rheostat 5 in the described sensor is thick-film resistor slidingtype rheostat.
Described fuel-quantity transducer device, its rheostat 5 is connected with the connecting rod 7 of float.Float 8 positions change and change along with the liquid level in the fuel tank 9, by connecting rod 7, liquid level in the fuel tank 9 is changed the resistance change that is converted into fuel-quantity transducer rheostat 5, to realize the curent change by rheostat 5, and pass through electrical signal 1 with its output, realize the control to fuel tank 9 fuel amounts.
Use thick-film resistor slidingtype rheostat, rheostat is connected with float by connecting rod, and the thick film rheostat is connected with electrical signal, by float the variation of fuel tank liquid level is converted to rheostatic resistance change, thereby realize the curent change of electrical signal, monitor accurately, reliably the residual fuel amount in the fuel tank.
Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that in the situation that does not break away from principle of the present utility model and spirit and can carry out multiple variation, modification, replacement and modification to these embodiment that scope of the present utility model is by claims and be equal to and limit.
