A drive transmission apparatus includes a dog clutch including a dog gear assembly and a dog ring, which are configured for rotation about a rotational axis and relative axial adjustment between an engaged condition in which torque can be transmitted between the dog gear assembly and the dog ring, and a disengaged condition in which torque cannot be transmitted. The dog gear assembly includes a dog gear, a retractable dog assembly configured for movement relative to the dog gear between an extended position and a retracted position, and a control element that controls movement of the retractable dog assembly. The dog ring includes a plurality of first dogs and the dog gear assembly includes a plurality of second dogs that engage the first dogs in the engaged condition, and that are disengaged from the first dogs in the disengaged condition. The second dogs include a plurality of fixed dogs that are mounted on the dog gear and a plurality of retractable dogs of the retractable dog assembly.

A hybrid module is configured for arrangement in a torque path upstream from a transmission and downstream from an internal combustion engine. The hybrid module includes a hybrid drive unit including an electric motor including a rotor. The hybrid module also includes a torque converter and a connector non-rotatably fixing the rotor to the torque converter. The connector includes a first section non-rotatably fixed to the rotor, a second section non-rotatably fixed to the torque converter and a retainer axially fixing the first section and the second section together in an intermeshing arrangement so the first section and the second section are non-rotatably fixed together.

A clutch device configured for a transmission may include a first body and a second coaxially mounted to the first body; a friction element mounted between the first body and the second body; a friction piston configured to axially press the friction element by use of hydraulic pressure; a retractable mechanism including a dog clutch, which is configured to restrict rotation between the first body and the second body, and repeatedly engaging and disengaging the dog clutch by repeatedly applying pressure in axial direction thereof; and an operation piston configured to provide pressure to the retractable mechanism in an axial direction of the retractable mechanism.

An electric drive axle including a first gear and an idler shaft having a second gear and a third gear disposed thereon, wherein the second gear cooperates with the first gear. A clutch assembly selectively couples a planetary gear system to one of the second gear and the third gear, wherein the planetary gear system is configured to produce a predetermined gear ratio between the second gear and the third gear.

A dual-shaft clutch varying speed device includes a drive unit, an input shaft, an output shaft, a housing, at least an odd-numbered clutch unit and at least an even-numbered clutch unit. The input shaft having an input gear is coupled with the drive unit. The output shaft, having an end thereof penetrate through the input shaft and the drive unit, has at least an odd-numbered output gear and at least an even-numbered output gear. The housing has a housing gear. The at least one odd-numbered clutch unit being furnished at the inner part of the housing has an odd-numbered clutch shaft and an odd-numbered clutch gear which is meshed with the odd-numbered output gear. The at least one odd-numbered clutch unit has an even-numbered clutch shaft and an even-numbered clutch gear which is meshed with the even-numbered output gear.

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.
