摘要： Various methods and systems are provided for an dual-faced clutch collar for a transmission. In one example, a dual-faced clutch collar positioned on an output shaft of a gearbox comprises a clutch collar spline, where the clutch collar spline mates with the output shaft; a first face having a first set of axially protruding teeth to engage a high torque coupling, the first set of teeth having a first profile; and a second face having a second set of axially protruding teeth to engage a low torque coupling; the second set of teeth having a second profile; the second profile being different from the first profile. The first profile may be a courser tooth profile, to allow for maximum load carrying capacity, and the second profile may be a finer tooth profile, to allow for quicker gear engagements and more neutral space (e.g., due to reduced tooth depths).

摘要： A shifting device for a drivetrain of a motor vehicle, includes a housing which a first and a second drive shaft are rotatably mounted. The first and second drive shafts are arranged coaxially to one another such that they have a common axis of rotation. The shifting device also includes a shiftable clutch device which is arranged between the first and the second drive shaft. The clutch device has an open shift position in which the first drive shaft is freely rotatable with respect to the second drive shaft, and the clutch device has a closed shift position in which the first drive shaft is connected non-rotatably by the clutch device to the second drive shaft. A control element is displaceable in the direction of the axis of rotation of the drive shafts and, depending on its displacement position, shifts the clutch device to the open or closed shift position. The control element is formed by a sliding sleeve which surrounds at least one of the two drive shafts, and a gear element is provided on an outer circumference of the sliding sleeve.

摘要： A dog clutch comprises first (160) and second (170) drive shafts, the drive shafts being connectable to one another by a dual spline connector (150). The dual spline connector is movable along a longitudinal axis of the first (160) and second (170) drive shafts and is provided with an internal spline that mates with an external spline of the first drive shaft. The dual spline connector is further provided with an external spline that upon axial movement may be connected or disconnected to an internal spline of the second drive shaft. Either or both of the external spline of the dual spline connector and/or the internal spline of the second drive shaft is or are provided with means for allowing partial connection of the internal and external splines.

摘要： A transmission includes a gear train, a transmission shaft driven by the gear train, a transmission casing incorporating the gear train and the transmission shaft, an axle driven by the gear train, a power take-off (PTO) unit attached to the transmission casing, and a parking brake. The transmission shaft and the axle are extended parallel to each other. The PTO unit includes a PTO input shaft, a PTO shaft, and a PTO drive train transmitting power from the PTO input shaft to the PTO shaft. The PTO input shaft is connected coaxially to the transmission shaft so as to receive power from the transmission shaft. The parking brake is provided on the transmission shaft or the PTO input shaft.

摘要： An electromagnetic clutch device includes meshing member connected to a first rotational member, a biasing member that biases the meshing member in a direction where a second meshing portion is meshed with a first meshing portion, and a pressing mechanism including a locking portion that presses the meshing member against a biasing force of the biasing member so as to axially move the meshing member. The locking portion is axially immovable relative to the second rotational member, and a cylindrical cam member is provided with a plurality of locked portions to be locked at different axial positions. Locking of the locking portion is shifted from one of the plurality of locked portions to another locked portion placed at a different axial position, and friction torque is caused to synchronize rotation of the first rotational member with that of the second rotational member.

摘要： An exemplary clutch device of an electrified vehicle includes a first member having a plurality of lugs about an axis, and a second member including a plurality of apertures. The plurality of lugs are selectively moveable axially into corresponding apertures to couple together rotation of the first member and the second member. Interfaces between the first member and the second member when under positive torque are angled differently than interfaces between the first member and the second member when under negative torque.
