摘要:
An axle assembly having a tapered spline arrangement. The axle assembly may include a first shaft that may have a first spline and a clutch collar that may have a clutch collar spline that may be disposed in a hole that may receive the first shaft. The first spline and the second spline may be tapered in opposite directions.

When a piece 7 and a sleeve 8 are engaged with each other, an engagement device 1 controls an actuator 9 to move the sleeve 8 in a direction approaching the piece 7 with the piece 7 rotating in a negative rotation direction (a direction in which small tooth surfaces 11a of dog teeth 11 of the piece 7 and small tooth surfaces 12a of dog teeth 12 of the sleeve 8 face and approach each other) relative to the sleeve 8, and further controls a first motor generator MG1 to change the rotation speed of the piece 7 from a negative rotation speed to zero or more after a predetermined stroke condition for the movement of the sleeve 8 relative to the piece 7 is satisfied. Accordingly, it is possible to reliably perform the engagement and improve the durability.

A gardening tool includes a motor (10), a working assembly (20) for performing a function of the gardening tool, and a transmission system (30) for causing the motor (10) to drive the working assembly (20). The transmission system (30) includes a first clutch member (31), a movable member (33) that is moveable from a first position to a second position, a bias member (34) for biasing the movable member (33) to the first position, and a second clutch member (32) configured to rotate with the first clutch member (31) when the movable member (33) is biased to the first position and to rotate relative to the first clutch member (31) when the movable member (33) is located at the second position.
摘要:
An automatic shift apparatus (13) including a rotation shaft (23, 24), a dog clutch gear shift mechanism (252), and a control unit (26). The control unit (26) supplies a predetermined electric current (Ia) to a shaft moving apparatus (313) to move a sleeve (312) in an engaged state engaged with one of a first clutch ring (281) and a second clutch ring (282) and supplies a braking electric current (ID) smaller than the predetermined electric current (Ia) to the shaft moving apparatus (313) to exert a braking force on the sleeve (312), the braking force directed in the opposite direction relative to a direction of movement of the sleeve (312), before a spline (312a) of the sleeve (312) disengages from a first dog clutch portion (281 a) or a second dog clutch portion (282a) of the mentioned one of the first clutch ring (281) and the second clutch ring (282).

A dog clutch control unit for an automatic transmission (13) includes: a dog clutch transmission mechanism including: a rotating shaft; a clutch ring (30, 32, 44, 46); a clutch hub (34); a sleeve (36) fitted to the clutch hub by means of a spline; an axially moving unit (40); a dog clutch portion (30a); and a stroke position sensor (38), the spline having high teeth higher than remaining low teeth, and the dog clutch portion including the same number of clutch front teeth as the high teeth, and the dog clutch portion including clutch rear teeth; and a control unit (10) configured to control an action of the axially moving unit on the basis of a detected position detected by the stroke position sensor.
