Inching gear engagement controlling device

Abstract

The invention relates to an inching gear engagement controlling device comprising a signal acquisition circuit, an input control signal circuit, a display circuit, a microcomputer controller, and an output control circuit, wherein the microcomputer controller is used for receiving and detects gear signals acquired by the signal acquisition circuit, displaying the gear signals by the display circuit which is connected with the microcomputer controller, receiving control signals transmitted by the input control signal circuit, and transmitting the control signals to the output control circuit; the output control circuit is used for receiving the control signals from the microcomputer controller to drive an input shaft to carry out micro-rotation to finish an inching gear engagement operation. According to the inching gear engagement controlling device disclosed by the invention, problems that gear engagement is difficult, repeated apical teeth of gear engaging components are impacted, the end surfaces of the gear engaging components are cracked and broken and the like due to the defects of the prior art are solved, the gear engagement times can be reduced, the labor strength of operators is reduced, and the success rate of gear engagement and the operation efficiency are improved; and meanwhile, an interlocking protection function is provided so that a starter, a hydraulic motor and the like of an engine can be protected, the safety and the reliability of vehicle devices are ensured, the damage to the vehicle devices and other train operation accidents caused by the error operation are prevented.

Description

technical field [0001] The invention relates to a jogging gear shifting control device. Background technique [0002] When the vehicle is in gear, at present, the shifting fork is driven by the driving shift device to drive the sliding sleeve to move. Through the engagement between the inner splines of the sliding sleeve and the outer splines of the input shaft and the output shaft, the sliding sleeve will The input shaft and the output shaft are connected as a whole to realize its power transmission. Or the power transmission is realized by meshing the external splines or gears of the sliding sleeve with the splines or gears of the output part. However, during the actual shifting operation, since the teeth and grooves of the splines or gears that need to be meshed are not necessarily in the right alignment state, it often occurs that the "additional teeth" cannot be shifted, and sometimes even due to repeated shifting The top teeth lead to problems such as cracking of the...

However, during the actual shifting operation, since the teeth and grooves of the splines or gears that need to be meshed are not necessarily in the right alignment state, it often occurs that the "additional teeth" cannot be shifted, and sometimes even due to repeated shifting The top teeth lead to problems such as cracking of the end face of the meshing parts, so it is necessary to improve the existing technology to improve the success rate of gear shifting
