INDEPENDENT WHEEL SHIFTABLE WHEEL DRIVES
Described herein are systems and techniques for utilizing a powered axle that includes a plurality of transmissions. The powered axle may include separate transmissions to power wheels on opposite ends of the powered axle. Each transmission of the powered axle may be operated independently of the other transmission. As such, the plurality of transmissions of the powered axle may be shifted independently of each other. Various control schemes may be provided for operation of such transmissions.

SYSTEMS AND METHODS FOR CONTROLLING SKID-STEER POWER MACHINES
A power machine can include a control device configured to select a ground-engagement mode from a plurality of ground-engagement modes. An operator input can be received from an operator input device to command movement of one or more drive actuators to provide turning travel. The one or more drive actuators can be commanded to provide modified turning travel based on the selected ground-engagement mode.

EFFICIENT WHEEL
An electrical family car, including: an electrically driven motor; and wheels with a radius larger than 90 cm. In such cars one of the dominating energy losses is directly related to the car axial to wheel friction. The car efficiency could therefore be increased by increasing the car wheel diameter which could yield a larger traveling distance for the same axial to wheel friction related energy loss.

Electric transaxle with integral power generating device
The invention comprises a transaxle having an electric motor that is controlled by a vehicle user and that drives at least one output axle. The transaxle includes a power generating device that powers the electric motor and a reduction gear train engaged to and driven by the electric motor. The transaxle includes a common housing in which the power generator, the electric motor, and the reduction gear system are each disposed. In dual-axle systems, the transaxle also includes a differential engaged to and driven by the reduction gear system to power a pair of oppositely extending output axles. The differential is also disposed within the common housing.
RUNNING GEAR
Aspects of the invention are directed to running gear for transport devices comprising a guide ring, a wheel carrier configured and arranged to be pivoted within the guide ring about a vertical main axis of rotation and two wheels configured and arranged to be rotated about a common axis of rotation, and an inner ring pivotably mounted in the guide ring via a rotary bearing about the main axis of rotation, and the wheel carrier is pivotably mounted via at least one pivot bearing about a pivot axis perpendicular to the main axis of rotation.

Excavator and method of controlling excavator
An excavator includes a lower travelling body; an upper turning body mounted on the lower travelling body; a hydraulic pump installed in the upper turning body; a travelling hydraulic motor that is a variable displacement type motor configured to move the lower travelling body by being driven by hydraulic oil discharged by the hydraulic pump; and a control device configured to control a motor capacity of the travelling hydraulic motor so as to be switchable between a plurality of levels. The control device switches the motor capacity to a low rotation setting upon detecting that an operation for changing a travelling direction of the lower travelling body is performed.
