Embodiment Construction

[0015] Examples such as figure 1 with figure 2 As shown, a non-contact gear sensor device includes a shift pull arm 1 and a gear sensor 2, the shift pull arm 1 is fixedly connected with a magnetic induction device 3, and the gear sensor 2 is arranged on the magnetic induction device 3 Within the sensing range, the gear sensor 2 is connected with a sensor bracket 4, and the sensor bracket 4 is fixedly connected with the gearbox housing.

[0016] The magnetic induction device 3 and the gear sensor 2 are independently installed respectively, and the shift pull arm 1 is fixedly connected with the shift shaft 5. When the shift shaft 5 rotates, the shift pull arm 1 and the magnetic induction device 3 rotate accordingly, and the magnetic induction device 3 and the magnetic induction device 3 rotate accordingly. The relative position between the gear sensors 2 changes, and the magnetic flux passing through the gear sensors 2 changes accordingly. The gear sensor 2 outputs a signal th...

Abstract

The invention relates to a non-contact type gear sensing device which comprises a gear shifting pulling arm and a gear sensor, wherein the gear shifting pulling arm is fixedly connected with a magnetic induction device; the gear sensor is arranged in the position within the induction range of the magnetic induction device; the gear sensor and the magnetic induction device are respectively and independently mounted; when gear shifting is performed, the magnetic induction device rotates along with the gear shifting pulling arm, the position of the magnetic induction device relative to the gear sensor is changed, and the change of magnetic flux of the magnetic induction device is received by the gear sensor, so that monitoring of the gear sensor to the change of gear information is realized, accuracy and stability in an output signal are realized, and the service life of the gear sensor is long.

Description

technical field [0001] The invention relates to a gear sensing device, in particular to a non-contact gear sensing device, which belongs to the technical field of machinery. Background technique [0002] The gear sensor is an angle sensor installed on the automatic transmission of the car. It is mainly used in the control system of the automatic transmission of the car. The automatic transmission control system of the car implements precise motion control through the position information of the shift shaft of the automatic transmission provided by the gear sensor. Realize the moving shift and swing shift of the transmission shift fork shaft and the combination of the clutch. The gear sensor is the most important measurement and control link in the automatic transmission control system. Whether the measurement accuracy of the gear sensor determines the reliability, safety and smoothness of the automatic transmission. At present, most of the commonly used gear sensors are con...
