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.

The present disclosure discloses an electric assembly and a vehicle having the same. The electric assembly includes: a box assembly; a motor, disposed in the box assembly; a transmission, disposed in the box assembly, where the transmission is power-coupled to the motor; and a controller, disposed outside the box assembly, and fixedly connected to the box assembly.

An axle assembly for a low floor vehicle is described herein. The axle assembly includes an axle housing and a drive unit for driving a wheel assembly. The axle housing including a first gearbox, a second gearbox and a cradle assembly coupling the first gear box to the second gear box. The axle assembly includes first and second hub assemblies that form a first axis of rotation. The first gearbox includes an electric motor that is coupled to a transmission used to rotate an output shaft. The first gearbox also includes a differential mounted for rotation with the transmission and a first drop box mounted for rotation with the differential. The axle assembly also includes a portal axle mounted for rotation with the first drop box and extends from the first gearbox to the second gearbox wherein the portal axle forms a second axis of rotation that is offset from the first axis of rotation of the hub assemblies. The second gearbox includes a second drop box mounted for rotation with the portal axle and is adapted to drive the second hub assembly.

A lubricant supported electric motor assembly includes an electric motor module, a shifting and first stage module, and a final drive module sequentially operably interconnected with one another for producing drive torque that is ultimately conducted to a wheel of a vehicle. The electric motor module includes a stator and a rotor defining an internal rotor cavity. The shifting and first stage module is disposed within the internal rotor cavity and includes a first planetary gear reducer assembly and an output gear selectively coupleable to said first planetary gear reducer assembly. The final drive module is disposed adjacent the shifting and first stage module and includes a second planetary gear reducer assembly operably coupled with the output gear. A shifting mechanism establishes selective coupling between the first planetary gear assembly and the output gear to transfer adjustable torque from the shifting and first stage module to the final drive device.

A drive axle of an electric vehicle has first and a second drive wheels (R1, R2) with wheel axles (a1, a2), a first electric machine (EM1) and a second electric machine (EM2) with a common rotation axis (m), a transmission (G3) with a transmission input shaft (EW) and a transmission output shaft (AW), and an axle differential (DI) with a differential input (DIK) and two differential output shafts (3a, 3b). The first electric machine (EM1) is connected to the transmission input shaft (EW) and the transmission output shaft (AW) is connected to the differential input (DIK). The second electric machine (EM2) can be connected as an additional drive when necessary.

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.

A driving force transmitting device includes an axle housing and a transaxle main body. The axle housing includes a supporting body and two shafts extending in opposite directions from the supporting body. The supporting body has an internal space. The transaxle main body is supported by the supporting body. The axle housing further includes a first breather plug. The first breather plug is fixed to the supporting body and is configured to discharge a gas in the internal space to an outside. The transaxle main body includes a gear mechanism, a case that accommodates the gear mechanism, and a second breather plug. The gear mechanism is configured to transmit a driving force. The second breather plug is fixed to the case and is configured to discharge a gas in the case to the outside. The second breather plug is located in the internal space.

A portal gear box assembly for an all-terrain vehicle includes a portal gear box housing with a set of gears contained therein, and a plurality of heat-radiating fins extending from the housing wall and effective to radiate heat from the housing at a faster rate than would be radiated in the absence of the fins. The fins may extend outward or inward from the housing, and may be formed integrally with one or more of the walls of the housing, or may be removably attached to the housing. Preferred fins comprise a generally rectangular, planer surface extending radially from a wall of the housing.

A portal gear box assembly for an all-terrain vehicle includes a sealed portal gear box housing having an interior housing space that contains a set of gears for linking an axle to an output shaft. An expandable space is in fluid communication with the interior housing space, and is adapted to allow pressurized fluid contained in the interior housing space to flow into the expandable space, thus expanding the volume of the expandable space and reducing the pressure within the interior housing space. The expandable space may be provided in the form of a bellows whose volume can be changed by expansion or contraction of a fluid contained therein. A fluid is contained within the portal gear box housing and within the expandable space.

The expandable space may be mounted externally to the portal gear box housing, and may be connected to the portal gear box housing by a conduit effective for allowing fluid to pass between the portal gear box housing and the expandable space. The expandable space and its connecting conduit are effective for allowing air to flow from within the portal gear box housing to the expandable space when an increased air pressure within the portal gear box is encountered, thus mitigating against a build-up of air pressure within the portal gear box housing.
