Abstract: A bogie for a forestry vehicle is disclosed that includes a bogie body, which has a first wheel hub for arrangement of a first wheel and a second wheel hub for arrangement of a second wheel. The bogie includes a swing arm pivotably hinged at a first end portion on the bogie body, and at a second end portion has a wheel hub for arrangement of a center wheel between the first wheel and the second wheel. The bogie further includes a spring and/or damper element, which at one end portion is hinged on the bogie body and at the other end portion is hinged on the second end portion of the swing arm and by means of which the swing arm is capable of being applied with force. A vehicle, in particular a forestry vehicle, is also disclosed having at least one bogie axle with such a bogie.

Abstract: The invention relates to a power split gearbox for a motor vehicle. The power split gearbox comprises a drive shaft which can be connected to an internal combustion engine in order to feed in torque, a first mechanical branch with a planetary gear mechanism arrangement, an infinitely variable second branch which can be connected to the first branch and comprises two adjustable energy converters which can be coupled to one another in energy terms and can be operated in each case in both directions, and at least one output shaft which can be coupled to the drive shaft via the first and the second branch.

Abstract: The invention relates to a drive device (10) for an automotive work machine, wherein the drive device (10) includes a first hydraulic motor (12a) coupled to a driven shaft (16), a second hydraulic motor (12b) and a coupling device (18), by means of which the second hydraulic motor (12b) can be coupled to the driven shaft (16) for torque addition in a first shift state, and can be decoupled from the driven shaft (16) in a second shift state. The coupling device (18) in turn includes at least one synchronizing body (20) with a conical friction surface (22) coupled to the second hydraulic motor (12b) and a gear wheel (24) with a corresponding friction surface (26) movable relatively to the synchronizing body (20) and coupled to the driven shaft (16).
