A drive includes at least one motor with a drive shaft and at least one output shaft which is in particular mechanically connected to a gear. The drive shaft and the output shaft are aligned substantially axially. The drive shaft and the output shaft each have a coupling portion through which a torque can be transmitted from the drive shaft to the output shaft by mechanical coupling. Each coupling portion is connected to the shaft thereof for rotation therewith and the coupling portions can be mechanically coupled by being axially plugged together.

This bogie and vehicle is provided with: a bogie body; a pair of travel wheels disposed on both sides of the bogie body in a direction intersecting with the traveling direction and capable of rolling motion on the traveling road surface of a track; a guide device guided along a guide rail and rotatably supported to the bogie body about the axial line along a vertical direction; and a pair of motors disposed between the pair of travel wheels of the bogie body and transferring a drive force to the pair of travel wheels.

A bogie for a railway vehicle has at least two track guide units, in particular at least two wheels sets. A traction motor is arranged in the region of one of the track guide units, hereinafter called the first track guide unit. The traction motor drives the first track guide unit. A power converter supplies power to the traction motor driving the first track guide unit. The power converter is arranged in a region of a different track guide unit, which is not driven, i.e., the second track guide unit.

The electric vehicle can include: a payload interface, a payload suspension, a chassis, a set of bumpers, a sensor suite, a controller, a chassis suspension, and an electric powertrain. The electric vehicle 100 can optionally include a payload adapter, a power source, a cooling subsystem, and/or any other suitable components. The electric vehicle functions to structurally support a payload, such as a cargo container (e.g., intermodal container, ISO container, etc.), and/or to facilitate transportation of a payload via railway infrastructure.

Systems and methods are provided for retrofitting, or producing, a truck assembly with a traction motor to propel a rail car or other vehicle. A traction drive frame assembly is an integrated unit combining the traction motor with its transmission means, an arrangement that prevents the traction drive frame from rotating when the traction motor is powered. The traction motor can be positioned in a space between a bolster and an axle of the truck assembly, and a jackshaft assembly can be positioned outside of the space. Then, one or more gears, pulleys, chains, etc. between the traction motor and the jackshaft assembly provide mechanical advantage and amplify torque transmitted from the traction motor to the jackshaft assembly. A second operable connection between the jackshaft assembly and the axle amplifies the torque a second time such that a relatively small traction motor propels a rail car or other vehicle.
