TRANSMISSION
Document Type and Number:
Japanese Patent JP2019019891
Kind Code:
A
Abstract:
To reduce wear by properly fitting a sleeve tooth part and a gear tooth part.SOLUTION: A transmission 10 has: a drive mechanism 15 for fitting and releasing a sleeve tooth part 56 of a sleeve to/from a gear tooth part 26 of a gear change gear by imparting a drive force for moving the sleeve to a rotation axis Xa direction to the sleeve; a phase angle difference detection part 92 for detecting a phase angle difference between the sleeve tooth part 56 and the gear tooth part 26; a target trajectory decision part 93 for deciding a target trajectory R of the sleeve tooth part 56 when fitting the sleeve tooth part 56 to the gear tooth part 26 on the basis of the phase angle difference between the sleeve tooth part 56 and the gear tooth part 26; and a drive control part 96 for controlling a drive force Fa imparted to the sleeve by the drive mechanism 15 on the basis of the target trajectory R. In a collision prediction zone C in which a collision of the sleeve tooth part 56 and the gear tooth part 26 is predicted, the drive control part 96 performs a correction for increasing the drive force Fa imparted to the sleeve.SELECTED DRAWING: Figure 8
