System and method for monitoring range gear transmission gear

Abstract

The invention discloses a system and method for monitoring a range gear transmission gear. The system comprises a detecting system, a single-chip microcomputer controller and a display panel installed in a cab. The detecting system comprises two rotating speed sensors, a gear detecting device and an auxiliary box gear detecting device, wherein the two rotating speed sensors are installed on a transmission and used for measuring the rotating speed of an output shaft of the transmission and a middle shaft of a main box, and the gear detecting device and the auxiliary box gear detecting device are installed at the positions of a gear shifting handle. The single-chip microcomputer controller is connected with the detecting system and the display panel. By means of the system and method, the two rotating speed sensors are adopted, the rotating speed of the transmission is directly monitored through the single-chip microcomputer controller, the rotating speed of an engine is indirectly monitored through the single-chip microcomputer controller, various indication signals sent by the display panel are monitored, analyzed and combined according to the gear detecting device installed on the gear shifting handle, safety operation of the range gear transmission can be guaranteed, damage to the manual transmission is reduced, the service life of an auxiliary box synchronizer is prolonged; meanwhile, various safe or dangerous signals are given to a driver, and the travelling safety is guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of transmission safety devices, and particularly relates to a monitoring system and a monitoring method for the gears of a range gear transmission. Background technique [0002] The transmissions used on commercial vehicles mainly include automatic transmissions and manual transmissions. At present, manual transmissions occupy a dominant position in the domestic transmission market. The general manual transmission has no gear display and safety prompt function. If there is no gear display, sometimes it may happen that the gear is not in place, but the driver is not aware of it. The engine overspeed can only be passively protected by the engine itself. If the engine itself does not have overspeed self-protection function, shifting overspeed may cause damage to the engine. For the range gear manual transmission, the auxiliary box synchronizer is a wearing part. If the driver shifts to a low gear when the vehic...

AI Technical Summary

Problems solved by technology

Due to the negligence of the driver or the abnormal flameout of the transmission, the transmission may not be in neutral when the engine is ignited. At this time, the car may suddenly shift forward, which not only affects the performance and life of the car transmission system, but also may be dangerous.
