A method of manufacturing a driving drum includes: molding a first cylindrical member including first large- and small-diameter parts, a diameter of an outer circumferential surface of the first small-diameter part being smaller than that of the first large-diameter part; molding a second cylindrical member having second large- and small-diameter parts, a diameter of an inner circumferential surface of the second large-diameter part corresponding to the diameter of the outer circumferential surface of the first small-diameter part, a diameter of an inner circumferential surface of the second small-diameter part corresponding to that of the first small-diameter part, and the diameter of the inner circumferential surface of the second small-diameter part being smaller than that of the second large-diameter part; and forming a first cam groove between the first and second small-diameter parts and forming a second cam groove between the first and second large-diameter parts.

A drivetrain system including an axle assembly that may have an electric motor module, a gear reduction module, a drive pinion, a differential assembly, an auxiliary shaft, and a shift collar. The shift collar may selectively couple the auxiliary shaft, the drive pinion, and the gear reduction module in various combinations.

In a vehicle drive transmission device, a transmission includes an intermesh first engagement device, a frictional second engagement device, a first drive device configured to drive the first engagement device, and a second drive device configured to drive the second engagement device. The first drive device includes a first shift drum, a first cam mechanism configured to convert rotational motion of the first shift drum into linear motion, and a first transmission mechanism configured to perform the linear motion. The second drive device includes a second shift drum, a second cam mechanism configured to convert rotational motion of the second shift drum into linear motion, and a second transmission mechanism configured to perform the linear motion. The first shift drum and the second shift drum are connected so as to rotate integrally with each other via a drive shaft. A drum drive source is provided to drive the drive shaft.

A drive mechanism that drives an axially moving portion in an axial direction includes a drive portion that reciprocates a first member along an intersecting direction that is a direction that intersects the axial direction, a conversion portion that converts a reciprocating motion of the first member along the intersecting direction into a reciprocating motion of a second member along the axial direction, and a connecting portion for connecting the second member and the axially moving portion such that the axially moving portion reciprocates along the axial direction as the second member reciprocates along the axial direction.

A first cylindrical member including protrusions on an end face is formed in an axial direction, the end face having projections and recesses in the axial direction so as to correspond to cam profiles of first and second cam grooves, a second cylindrical member having an end face having projections and recesses so as to correspond to the projections and the recesses of the first cylindrical member is formed, and at a position where the projections and the recesses of the first cylindrical member correspond to the projections and the recesses of the second cylindrical member, the protrusions of the first cylindrical member are joined to the end face of the second cylindrical member, to thereby form the first cam groove on an inner side of the protrusions in the circumferential direction and form the second cam groove on an outer side of the protrusions in the circumferential direction.

An actuating unit for actuating shift elements of a transmission (G) includes a shaft (1) at least partially configured as a hollow shaft and at least three shift elements (A, B, C, D). At least two of the at least three shift elements are spatially separated from each other by at least one of the three shift elements. A first actuating element (S1) is configured as a hollow shaft and a second actuating element (S2) is guided within the first actuating element (S1). A mechanical coupling of the two actuating elements (S1, S2) with the at least three shift elements (A, B, C) takes place through a plurality of recesses (11, 12, 13) in the shaft (1) and through at least one recess (21) in the first actuating element (S1) in such a way that the at least two shift elements (A, B, C, D) spatially separated from each other are actuatable by precisely one of the two actuating elements (S1, S2).
