Abstract

The invention relates to a non-contact vehicle gear sensor, wherein the axial top part of a shell of the non-contact vehicle gear sensor is equipped with an upper cover plate while the axial bottom part of the shell of the non-contact vehicle gear sensor is provided with a lower cover plate; a circuit board is arranged on the inner side of the upper cover plate; a hall chip is connected to the circuit board; the hall chip is located in the shell; the outer side of the hall chip is equipped with a hollow rotating shaft; a magnetic conducting ring is sleeved on the upper part of the hollow rotating shaft, corresponding to the hall chip; one side wall in the magnetic conducting ring is connected with a magnet; the magnet corresponds to the hall chip; a locating ring is radially arranged on the middle part of the outer side of the hollow rotating shaft; a return spring is sleeved on the hollow rotating shaft on the lower part of the locating ring; and the upper end and the lower end of the return spring are located on the locating ring and the lower cover plate. According to the non-contact vehicle gear sensor disclosed by the invention, the contact abrasion problem is solved; the service life of the sensor is largely prolonged; and the working reliability and the safety are improved.

Description

technical field [0001] The invention belongs to the technical field of sensors, and in particular relates to a vehicle gear position sensor. Background technique [0002] The electric mechanical automatic transmission (AMT) is based on the conventional manual transmission, with an additional set of electronic control devices, which can automatically control the clutch and shift lever of the manual transmission, so that the disengagement and engagement of the clutch are automatic. of. AMT gearboxes combine the advantages of high transmission efficiency of mechanical gearboxes and convenient operation of automatic gearboxes, and are widely used in various types of vehicles. [0003] The AMT gearbox realizes the shifting and swinging shifting of the shifting fork shaft of the gearbox and the engagement of the clutch by controlling the rotation angle of the motor. The gear position sensor is the most important measurement and control link in the AMT transmission system. The ac...
