An aircraft cabin blower system comprises a cabin blower including a compressor configured to provide air to a cabin of the aircraft; a variable drive system configured to drive the compressor and including an electric variator and a summing gearbox; and a main transmission configured, when operating in a blower mode, to receive mechanical power from a gas turbine engine and input mechanical power to the summing gearbox in a forward direction; and configured, when operating in a starter mode, to receive mechanical power from the summing gearbox and input mechanical power to the gas turbine engine. The aircraft cabin blower system further includes a first one-way rotation device adapted to permit free rotation of the main transmission in the forward direction and to prevent rotation of the main transmission in a reverse direction opposite to the forward direction.

A transmission mechanism is provided with an output gear drivingly coupled to at least one of a pair of output members and placed coaxially with the pair of output members. A direction in which a rotating electrical machine and an inverter device are arranged side by side in an axial view is defined as a first direction. A direction perpendicular to both an axial direction and the first direction is defined as a second direction. A first output member that is one of the pair of output members is placed between the rotating electrical machine and the inverter device in the first direction, at a position in the second direction where both the rotating electrical machine and the inverter device are placed. The output gear is placed in such a manner as to overlap each of the rotating electrical machine and the inverter device in the axial view.

An axle assembly having an interaxle differential unit. The interaxle differential unit includes first and second side gears and a gear nest but does not have a case. The gear nest includes a spider having at least one spider shaft, a pinion gear that is rotatably disposed on the spider shaft, and a pinion gear retainer that is fastened to the spider shaft to retain the pinion gear.

The invention relates to a method for producing a differential housing having at least one machined bearing body and a machined gearing. In order to improve the differential housing in terms of production technology and/or function, the differential housing which has the bearing body is cast from a nodular cast iron material before the differential housing which has the bearing body and the gearing is machined.

The present document relates to an electric drive axle comprising an electric motor, a first planetary gear set, a second planetary gear set, and a differential assembly. The electric motor is drivingly connected or drivingly connectable to the differential assembly via the first planetary gear set and via the second planetary gear set.
