A twin-wheel drive module for driving two vehicle wheels which are disposed spaced axially from one another and rotatable around two axes of rotation aligned with one another. For driving each vehicle wheel, provision is made for a traction motor having a motor shaft disposed in parallel to the axes of rotation, a transmission having an input shaft which is connected to the motor shaft of the traction motor and an output shaft in alignment with the axes of rotation, and a second transmission. The second transmission has an input shaft, which is connected to the output shaft of the first transmission, and an output shaft which rotates around a common axis of rotation with the input shaft configured to receive the vehicle wheel.

The technology disclosed herein can include a motor unit having a motor with a motor gear to rotate a drive shaft and a drive gear. A manual input shaft can also be configured to transmit rotation to the drive shaft. The motor can have a central axis that forms an angle of less than 90 degrees with a plane substantially defined by an outer surface of a gear box coupled to the motor. A mounting bracket is configured to allow mechanical communication between the motor unit and an internal ring gear. The internal ring gear can be mounted to a vehicle and a turret can be pivotably disposed within the internal ring gear. A motor unit is mounted on the turret and a drive gear is rotatably mounted on the motor unit and in direct engagement with the internal ring gear.

The present invention relates to a rotary drive (100) comprising: an output shaft (330); a motor (20), acting on the output shaft (330) via a downstream gear mechanism (30); an energy-store module with a linear line of action and with transmission elements (32, 326) to apply pressure circumferentially to an eccentric cam disk (331) arranged on the output shaft (330) for conjoint rotation therewith; and an intermediate shaft (320), being offset in relation said line of action and being provided between the motor (20) and the output shaft (330). The transmission elements (32, 326) comprise a roller lever (32), having a cam-follower roller (326) spaced apart from the intermediate shaft (320), wherein the cam-follower roller (326), pressed circumferentially against the eccentric cam disk (331), interacts with the output shaft (330). The energy-store module is arranged on the motor side in relation to the intermediate shaft (320).

An electric vehicle can include an electric drive capable of moving the vehicles, together with a non-battery operative feature to enhance the performance of the vehicle, such as extending the range or increasing the power. The non-electrical enhanced feature is independent and not integrated with the electric drive, to enable the return of the vehicle design to pure electrical power with minimum modification.

Apparatus and associated methods relate to a motor-less cartridge ring gear engagement module (CRGEM) for a turret-rotating system that includes a main drive gear configured to rotate in a rotation plane, a manual input shaft that extends substantially orthogonal relative to the rotation plane, and a drive shaft that extends substantially orthogonal relative to the rotation plane, where the drive shaft and the manual input shaft extend substantially parallel to one another. In an illustrative example, both the main drive gear and a hand crank may be located on a top surface of the CRGEM. In some embodiments, a manual drive cap may be hingedly coupled to the gearbox and configured to rotate in a vertical plane that is substantially orthogonal to the rotation plane. At least some examples may provide for a hand-operated, manual traverse unit that advantageously does not require electrical power to operate.

A motor vehicle comprises a primary drive machine with a primary drive shaft for receiving or outputting power, a secondary drive machine with a secondary drive shaft for outputting power, and a secondary torque transmission device having an input side and an output side. A torque initiated by the input side and discharged by the output side can be influenced by the secondary torque transmission device. The vehicle further comprises an energy storage device and an output device which supplies the power output to the vehicle. The primary drive machine can be operated in a first operating state in which power is output by the primary drive shaft, and a second operating state in which power is received by the secondary drive shaft via the primary drive shaft and said power can be stored as energy in the energy storing device.
