Definitions
- the invention relates to a device for measuring the temperature of a gear oil according to the preamble of claim 1.
- the invention has for its object to provide a device for measuring the transmission oil temperature, which offers increased reliability with little effort.
- a device for measuring the temperature of the oil in a transmission housing of a transmission is proposed with a temperature sensor that can come into contact with the oil in the transmission.
- the temperature sensor is arranged outside the oil sump in the gearbox.
- the temperature sensor comes into contact with the oil during the operation of the transmission via the wetting with spray oil.
- the spray oil is whirled up by rotating elements of the transmission, the rotating elements in an advantageous embodiment being gear wheels of the transmission.
- the temperature sensor is arranged in the immediate vicinity of a speed sensor with a rotating dial, so that the spray oil is sprayed through the dial onto the temperature sensor.
- Another advantageous embodiment shows a temperature sensor which comes into contact with the oil via a lubricating oil circuit during operation of the transmission.
- the temperature sensor can be arranged in the pressure region of the lubricating oil circuit, can be arranged directly in components of the transmission control electronics, or is integrated in a transmission switching device that contains the electronics and the shift actuator system.
- a further advantageous embodiment shows the temperature sensor integrated in another sensor, in particular in a speed sensor.
- the signals of a sensor of the transmission which is not primarily used for temperature detection can be evaluated in an electronic circuit for detecting the temperature.
- the internal resistance of a speed sensor can be detected and the change in the temperature of the gear oil in an electronic circuit can be evaluated by changing the internal resistance.
- Fig. 1 shows a transmission with a splash oil
- Fig. 3 shows the temperature sensor in a pressure oil line
- Fig. 4 shows the direct connection of the temperature sensor to the transmission control electronics.
- a transmission 2 which has an input shaft 6, an output shaft 8 and a clutch actuator 10 in a transmission housing 4.
- a plurality of gearwheels are located on the input shaft 6 and a main shaft 12 of the transmission 2.
- the gearwheel 14 shown here hurls while rotating while the transmission 2 is in operation Gear oil from the oil sump 16 in the gear housing 4 around.
- a gear actuator 18 is provided, which is embedded in the gear housing 4 here.
- the transmission actuator 18 contains both the transmission electronics and the shift actuator system.
- a temperature sensor 20 is located on the underside of the gear actuator 18 outside of the oil sump 16.
- the temperature of the transmission oil can be evaluated in an electronic evaluation unit, for example in the transmission actuator 18.
- a counting disc 38 is also set in rotation by the gear wheel 14.
- the oil sump 16 is connected to a pressure oil line 26 via a pump 24. At least one opening 28 is provided on the pressure oil line 26 of a lubricating oil circuit, from which spray oil sprays onto the temperature sensor 20, shown schematically by the arrow 30.
- Fig. 3 the same reference numerals have been used for the same components.
- branches from the pressure oil line 26 branch, in which the temperature sensor 20 is arranged directly.
- the transmission oil flows through or around the temperature sensor 20 directly.
- a circuit board 34 is schematically shown within the transmission actuator 18. shows.
- the temperature sensor 20 is directly connected to the printed circuit board without plug connections or arranged on the latter itself.
- the temperature sensor 20 can also be replaced by a speed sensor 36 used at the same location or in the immediate vicinity, the signals of which can also be used for evaluating the temperature in an electronic circuit, for example on the printed circuit board 34 within the transmission actuator 18.
- the speed sensor 36 can interact with a counting disk 38 (see FIG. 1), the rotation of which causes gear oil to be thrown onto either the temperature sensor 20 and the speed sensor 36.
