A dog clutch with ratcheting one-way clutch includes an axis, a dog clutch ring, a first ring, a second ring, and a plurality of rockers. The dog clutch ring has a plurality of first teeth. The first ring includes a plurality of second teeth, complementary to the first teeth, a first spline for receiving a first shaft, and a plurality of first pockets. The second ring includes a plurality of third teeth, complementary to the first teeth, a second spline for receiving a second shaft, and a plurality of second pockets. The plurality of rockers is disposed in a one of the plurality of first pockets or the plurality of second pockets for selectively engaging with the other one of the plurality of first pockets or the plurality of second pockets to prevent rotation of the first ring relative to the second ring in only one rotational direction.

A belt pulley structure of an engine is provided to prevent abnormal noise from generating between a belt pulley and a torsional vibration damper. The belt pulley structure includes a stepped portion that is formed in a shape that blocks a cavity in a radial direction thereof. The cavity is formed at a portion where a belt pulley and a torsional vibration damper face each other.

This work machine is provided with a clutch mechanism which is provided on a motive power transmission path between a drive source and a wheel. The clutch mechanism is provided with: a drive shaft with which drive force from the drive source is transmitted; a key member which is provided so as to be capable of moving relative to the drive shaft; a driven member which is driven by the drive shaft via the key member; an impelling member which impels the key member towards the driven member; and a ratchet holder which is provided with an engagement groove and a guide part, and which is provided so as to be capable of rotating coaxially with the drive shaft.

Methods and systems for a clutch assembly in an electric drive axle of a vehicle are provided. In one example, a clutch assembly in a gear train is provided that includes a locking clutch. The locking clutch includes a gear including a plurality of teeth having at least one tooth with a tapered end, an indexing shaft rotationally connected to an output shaft, a shift collar mounted on the indexing shaft, configured to translate on the indexing shaft into an engaged and disengaged configuration, and including a plurality of teeth on a face, where at least one tooth in the plurality of teeth in the shift collar includes a tapered end, and an indexing mechanism coupled to the shift collar and the indexing shaft and configured to accommodate for indexing between the indexing shaft and the shift collar during shift collar engagement.
