Vehicle speed sensor for new energy automobile transmission detection

Abstract

The invention relates to the related technical field of new energy vehicles, and discloses a vehicle speed sensor for new energy vehicle transmission detection, the vehicle speed sensor comprises a shell and a driving shaft, one end of the shell is in threaded connection with a shell cover, a receiving plate is fixedly mounted on one side of the inner wall of the shell, a contact pin is fixedly mounted on the surface of the receiving plate, and one end of the contact pin is positioned on the outer side of the shell. The transmission shaft and the driving shaft are connected through the transmission pipes, meanwhile, the transmission shaft is installed on the shell cover through the bearings, and therefore the multiple strands of transmission pipes are twisted to be in a rope shape through rotation of the driving shaft, power is provided for transmission, and the phenomenon that the driving shaft and the transmission shaft are not coaxial due to vibration is overcome. And when the transmission pipe is screwed in, the transmission shaft has a force trend of outward movement, so that the centering of the transmission shaft is enhanced through the bearing, the movement deviation between the magnetic wheel and the receiving plate is reduced, and finally, the purposes of detection accuracy and low-vibration transmission are achieved.

Description

technical field [0001] The invention relates to the technical field related to new energy vehicles, in particular to a vehicle speed sensor for detecting transmissions of new energy vehicles. Background technique [0002] The vehicle speed sensor detects the vehicle speed of the electronically controlled vehicle, and the control computer uses this input signal to control other functions such as engine idling, torque converter locking of the dynamic transmission, automatic transmission shifting, opening and closing of the engine cooling fan, and cruise control. [0003] In the application process of the vehicle speed sensor, such as the magnetoelectric vehicle speed sensor, the magnetic wheel is usually connected with the rotating shaft of the automobile gearbox, and then when the magnetic wheel rotates through the receiving board, the coil on the receiving board generates an AC signal from the pin Output to the control computer, so as to detect and adjust the moving parts su...
