An actuation system includes a power drive unit that drives a plurality of drive shafts that each has a first end individually connected to the power drive unit. The power drive unit includes a geartrain including a plurality of individual gears that are offset relative to each other along the gearbox, and a motor-driven rotation of one of the plurality of individual gears drives rotation of the other individual gears, and each of the plurality of individual gears rotates to drive rotation of a respective one of the plurality of drive shafts. A plurality of torque brakes is mounted to the gearbox, the torque brakes being mechanically coupled to respective individual gears and drive shafts. When the torque being passed through is above a predetermined threshold value, a locking of one of the torque brakes stops rotation of all gears simultaneously to maintain positional symmetry in the actuation system.

A gearbox comprises a differential gear train. The differential gear train comprises a ring gear assembly, a sun gear assembly, and a planetary carrier assembly connected to a planetary gear mechanism. The planetary carrier assembly comprises side plates. The side plates combine with gears to form high-pressure volume units and low-pressure volume units, and a throttle channel is connected between two volume units. The high-pressure volume unit is constructed in a meshing zone of the gears. All high-pressure volume units are connected and communicated with each other by means of a high-pressure oil channel on the planetary carrier assembly. The gearbox can reduce the volume of the high-pressure volume unit, simplify the structure and process, and improve the transmission efficiency and reliability

The present invention pertains to a drive connection for coupling an engine to a gearbox of a machine and which provides a fluid-tight sealing. Accordingly, a drive connection for coupling an engine to a gearbox of a machine is suggested, which comprises a housing having an inner cavity that extends from a first open end of the housing to a second open end of the housing and which is configured for accommodating and enclosing a clutch. The housing defines a first coupling interface at the first open end for coupling the drive connection to an engine and a second coupling interface at the second open end for coupling the drive connection to a gearbox, Furthermore, each coupling interface comprises a sealing member, wherein the housing and sealing members are configured to fluidically seal the inner cavity, when the drive connection is in a coupled state.

A geared motor includes a gear unit, a first, a second, or a third electric motor, and an adapter part situated between the gear unit and the electric motor. On its side facing the electric motor, the adapter part has a first, a second, and a third centering device, and on the side facing away from the electric motor, it is connected to the gear unit. The centering devices are radially set apart from one another, and the second centering device is situated radially between the first and third centering devices. The electric motor has an axially protruding centering ring, which is centered by only a single one of the centering devices of the adapter part, and the other centering devices are radially set apart from the centering ring and/or have no centering function, e.g., for the centering ring.
