Problems solved by technology
Neutral position sensors are generally perforated, switch-type, etc. The signal output of this structure is not very accurate and there is a risk of oil leakage at the switch. The magnet is generally external, and the development cost is high.
[0003] The reversing light switch is generally a mechanical contact type, which has the following disadvantages: (1) It is installed in the gearbox and is easily oxidized due to the high temperature of the gearbox at about 100 degrees Celsius; (2) The contact voltage is relatively large (150-300mv), There are sparks when the contacts are on and off, and the contacts are prone to heat, so they are easy to ablate and disconnect; (3) The life of the contacts is low

The invention provides a position sensor assembly for a manual transmission and the manual transmission. The manual transmission comprises a transmission shell and a gear shift shaft located in the transmission shell. The position sensor assembly comprises a magnetism converging body which is suitable for being arranged on the gear shifting shaft, a sensor which is suitable for being fixed on the outer surface of the transmission shell and is separated from the magnetism converging body by the transmission shell. The sensor is opposite to the magnetism converging body and comprises a shell, a circuit board, a Hall chip, a magnet and a connector clip, wherein the magnet is fixed in the shell. According to the position sensor assembly for the manual transmission, the sensor is arranged on the outer surface of the transmission shell, and therefore due to the fact that the installation manner of the sensor is a non-through manner, the risks of oil leakage of the transmission shell will not exist at the sensor.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a position sensor assembly for a manual transmission and the manual transmission. Background technique [0002] The neutral position sensor is a key component in the car's intelligent start-stop, one-key start and idle speed boosting system. Realization of idle speed boost function. Neutral position sensors are generally perforated, switch-type, etc. The signal output of this structure is not very accurate and there is a risk of oil leakage at the switch. The magnet is generally external, and the development cost is high. [0003] The reversing light switch is generally a mechanical contact type, which has the following disadvantages: (1) It is installed in the gearbox and is easily oxidized due to the high temperature of the gearbox at about 100 degrees Celsius; (2) The contact voltage is relatively large (150-300mv), There are sparks when the contacts are turned on and of...
