A two wheeled throwable robot comprises an elongate chassis with two ends, a motor at each end, drive wheels connected to the motors, and a tail extending from the elongate chassis. The throwable robot includes a pair of torque limiting mechanisms, each torque limiting mechanism being operatively coupled between a motor and a drive wheel. Each torque limiting mechanism comprises a drive flange portion, a driven flange portion and a plurality of rollers. A spring element provides a ring force that biases the rollers toward the driven flange portion.

An electric axle assembly having dual motors and dual disconnects allowing for selectably disconnecting either one of the motors so that either motor may operate as the primary drive motor. Each of the dual motors is coupled to a layshaft, and each disconnect is positioned between a gear reduction at the output of the motor and a gear reduction connected to the layshaft. The layshaft is coupled to a differential via a clutch and gear set, the gear set providing a two-speed transmission for power delivered from the layshaft to the differential.

A military vehicle include a driveline. The driveline includes a first driver including an engine, an energy storage system, an accessory drive coupled to the engine, a transmission coupled to at least one of the front axle or the rear axle, and a second driver coupled to the engine and the transmission. The accessory drive includes a plurality of accessories and a first motor. The first motor is electrically coupled to the energy storage system. The first motor is positioned to facilitate selectively driving the plurality of accessories. The second driver includes a second motor electrically coupled to the energy storage system.

An electric vehicle includes: an electric motor; a wheel that is driven by the electric motor; a power transmission mechanism that defines at least a part of a power transmission path between the electric motor and the wheel and that transmits rotational power of the electric motor to the wheel; a wheel brake that is provided on the wheel; an electromagnetic brake that stops rotation of the electric motor; and a controller that maintains a control value of a rotation speed of the electric motor at 0 and activates the electromagnetic brake when a vehicle speed becomes lower than or equal to a predetermined value close to 0.
