Title:
ENGAGEMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/115248
Kind Code:
A1
Abstract:
When engaging a piece (7) with a sleeve (8), the engagement device (1) controls an actuator (9) so as to move the sleeve (8) closer to the piece (7) while the piece (7) is rotating in the negative rotation direction with respect to the sleeve (8) (the direction in which the small tooth surfaces (11a) of the dog teeth (11) of the piece (7) and the small tooth surfaces (12a) of the dog teeth (12) of the sleeve (8) face and draw towards each other). After a specified stroke condition relating to the movement of the sleeve (8) with respect to the piece (7) is satisfied, the engagement device controls a first motor generator (MG1) so that the rotation speed of the piece (7) goes from a negative number to 0 or higher. As a result, engagement can be reliably accomplished and durability can be improved.
