Abstract

The invention discloses a fault monitoring system and method for an automobile transfer case, and relates to the technical field of vehicle-mounted monitoring equipment. The fault monitoring system comprises a rotating speed sensor, a monitoring device and an upper computer, wherein the rotating speed sensor is arranged on an output shaft of the transfer case, and the sensing surface of the rotating speed sensor faces the gear tooth top and the gear tooth root of the output shaft and is used for monitoring the real-time rotating speed of the output shaft; the monitoring device is in signal connection with the rotating speed sensor, is used for comparing the real-time rotating speed of the output shaft with a normal rotating speed threshold value and sends a clutch alarm signal when the real-time rotating speed is less than the normal rotating speed threshold value; the upper computer is in signal connection with monitoring equipment and is used for displaying the real-time rotating speed of the output shaft and displaying clutch alarm information according to whether the monitoring equipment sends the clutch alarm signal. By means of the fault monitoring system for the automobile transfer case, the working state, working time and fault information of the transfer case can be relatively comprehensively monitored, and fault alarm can be carried out, so that the accuracy and automation degree are high.

Description

technical field [0001] The invention relates to the technical field of on-board monitoring equipment, in particular to a system and method for fault monitoring of an automobile transfer case. Background technique [0002] With the development of current automobile technology, the functions of automobiles are becoming more and more abundant. In order to meet the functional requirements of multi-axis drive and various working conditions, it is generally necessary to use a transfer case to distribute and transmit the original power. The transfer case is the key component for distributing and outputting the engine power, and it is the basic condition to ensure the realization of energy conversion and other functions of the vehicle. If the transfer case of the car fails, the performance of the entire vehicle will be greatly reduced, and the power generation function and air conditioning function that rely on the output of the transfer case as an energy source will be completely ...
