An automatic transmission assembly includes a torque converter drivably engaged with a transmission. The torque converter has an impeller with a hub. The hub has an exterior surface, a hub end face, and a first chamfered edge between the exterior surface and the hub end face. A gear has an axial opening, a gear end face, and a second chamfered edge between the axial opening and the gear end face. First and second extensions extend from the second chamfered edge. The first and second extensions extend in a direction normal to the second chamfered edge. During indexing of the torque converter, the first and second extensions contact the first chamfered edge.

A device for transmitting a rotation movement includes first and second force transmission sections, each with a drive input and a drive output, and with a first chain guide. The chain guide is arranged between the drive input and output and accommodates an endless chain, which circulates between the drive input and drive output. A middle force transmission section with a middle drive input and a middle drive output, and with a conduit that is arranged between these. The conduit accommodates a hydraulic fluid and transmits forces between the first and the second force transmission section. The hydraulic fluid circulates between the middle drive input and the middle drive output and transmits push forces between the middle drive input and the middle drive output. The first drive output is coupled to the middle drive input, and the middle drive output is coupled to the second drive input.

A drive device for a vehicle having a combustion engine and a multistage manual transmission having first and second sub-transmissions, each of which has a separate input shaft. A first input shaft of the first sub-transmission couples, via a first clutch, the combustion engine or is assigned an electrical machine. A second input shaft of a second sub-transmission couples, via a second clutch, the combustion engine. The first input shaft is additionally assigned a start-up element having at least one hydrodynamic transfer element, which has first and second functional wheels which together form a working chamber. The working chamber can be filled with fluid in order to generate a hydrodynamic transfer torque such that at least one start-up function, affecting the first sub-transmission, can carried out by way of the start-up element.

The present invention relates to a method for heating a transmission (1) for a working machine having a plurality of hydraulically actuated shifting elements (8; 9; 10; 11; 12; 13). The method involves the sending (III) of a closing signal for closing shifting elements (8; 9; 10; 11; 12; 13) in order to block the transmission (1). In addition, the method entails pulsed actuation (V) for opening and closing of at least one of the closed shifting elements (8; 9; 10; 11; 12; 13) while the transmission (1) remains blocked. Furthermore, the present invention relates to a control unit which is designed to carry out such a method, and to a transmission for a working machine with such a control unit.
