A signal detection system and method for a hydromechanical gearbox

Abstract

A signal detection system and method for a hydraulic mechanical gearbox, using the ECU control unit of the hydraulic mechanical gearbox as the central controller, and realizing the hydraulic mechanical Transmission action control and information storage. Specifically: the ECU control unit of the hydraulic mechanical transmission will realize the status signals of the detected torque converter pump wheel speed, turbine speed, oil temperature, clutch signal, transmission neutral gear, reverse gear signal, etc. The communication and information storage of the controller and memory provide data sources for the automatic adjustment of heat dissipation power of the radiator of the hydraulic mechanical transmission, clutch overload protection, reversing radar, slow-moving warning and fault diagnosis, and avoid hydraulic pressure caused by slow-moving high temperature and clutch high temperature. Mechanical gearbox damage problems, while providing users with reversing radar prompts, fault diagnosis and other functions.

Description

technical field [0001] The invention relates to a signal detection system and method for a hydraulic mechanical gearbox, belonging to the field of automobiles and the technical field of special vehicle chassis. Background technique [0002] In order to meet the use requirements of modern military vehicles, it is required that the use status of the hydromechanical gearbox can be detected and stored. [0003] In particular, the reliability requirements of super-heavy military vehicles are high, so the data package requirements for vehicle health management are proposed, and the status detection of hydraulic mechanical gearboxes needs to be comprehensive, real-time and accurate. In the prior art, the speed change mechanism of the vehicle transmission system is only required to realize basic functions such as speed change, and it is impossible to detect the use status of the torque converter, retarder, clutch, gearbox and other components subordinate to the hydraulic mechanical ...

AI Technical Summary

Problems solved by technology

In the prior art, the speed change mechanism of the vehicle transmission system is only required to realize basic functions such as speed change, and it is impossible to detect the use status of the torque converter, retarder, clutch, gearbox and other components subordinate to the hydraulic mechanical transmission. Failure to establish a state detection foundation for fault warning, fault intervention, fault diagnosis, etc., will not effectively guarantee the safety of the hydraulic mechanical gearbox, or even the safety of the vehicle
