Signal detection system and method for hydraulic force mechanical speed changing box

Abstract

The invention provides a signal detection system and method for a hydraulic force mechanical speed changing box. A hydraulic force mechanical speed changing box ECU control unit is used as a central controller, movement control and information storage of the hydraulic force mechanical speed changing box are realized through two ways of collection built-in sensor state and vehicle control unit interaction. Specifically that the rotate speed of a torque converter pump wheel, turbine rotate speed, oil temperature, a clutch signal, speed changing box neutral position, reverse gear and other statussignals obtained by detection realize communication and information storage with the vehicle control unit and a storage through CAN bus, the hydraulic force mechanical speed changing box ECU controlunit provides data sources for automatic adjustment heat dissipation power of a hydraulic force mechanical speed changing box radiator, the overload protection of a clutch, a reversing radar, an amblecaution and fault diagnosis, the problem that the hydraulic force mechanical speed changing box is damaged caused by the amble high temperature and the clutch high temperature is avoided, and meanwhile functions such as reversing radar reminding and the fault diagnosis are provided for users.

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
