The invention includes first and second motors, first and second differential mechanisms, and first to eighth decoupling mechanisms. The first and second motors transmit power to left and right wheels. First differential mechanisms distribute the power from the first and second motors. The first and second mechanisms are interposed between the first differential mechanism and the left front wheel and between the differential mechanism and the left rear wheel. The third and fourth decoupling mechanisms are interposed between the first motor and the first decoupling mechanism and between the first motor and the second decoupling mechanism. The fifth and sixth decoupling mechanisms are interposed between the second differential mechanism and the right front wheel and the right rear wheel, respectively. The seventh and eighth decoupling mechanisms are interposed between the second motor and the fifth decoupling mechanism and between the second motor and the sixth decoupling mechanism.

Some embodiments relate to a vehicle corner module (VCM) connectable to a VCM-connection interface of a reference-frame of a vehicle platform (e.g. for regulating motion of a vehicle). Some embodiments relate to a multi-interface connection-element for connection of multiple electronic or flow vehicle subsystems of a vehicle to a Vehicle Corner Module (VCM). Related methods are disclosed herein.

A vehicle operating device including an operating member operable by a driver and configured to: issue, to a drive system, a command to apply a drive force in a forward direction when a first-direction operation of the operating member from its neutral position in a first direction is performed in a state in which the vehicle is at a stop or running forward; issue, to the drive system, a command to apply a drive force in a backward direction when a second-direction operation of the operating member from the neutral position in a second direction different from the first direction is performed in a state in which the vehicle is at a stop or running backward; and issue, to a brake system, a command to apply a braking force as an opposite-direction-operation-dependent braking force when the second-direction operation is performed in a state in which the vehicle is running forward.

A portal assembly has a housing for attachment to the vehicle axle and enclosing a gear assembly having an input gear linked to the axle shaft for rotating around a first rotational axis and an output gear positioned within a second lower rotational axis that converts rotation of the input gear to rotation of the output gear. An output axle is driven by the output gear for transferring rotational force to a unit bearing located outside of the housing. The unit bearing is attached to and transfers rotational force to a wheel hub.

The present teachings relate generally to a small remote vehicle having rotatable flippers and a weight of less than about 10 pounds and that can climb a conventional-sized stairs. The present teachings also relate to a small remote vehicle can be thrown or dropped fifteen feet onto a hard/inelastic surface without incurring structural damage that may impede its mission. The present teachings further relate to a small remote vehicle having a weight of less than about 10 pounds and a power source supporting missions of at least 6 hours.

A vehicle includes a frame, a first support member including a first end, a second end and an intermediate portion supporting a first axle receiver, a first bellows mounted to the first end of the first support member, a second bellows mounted to the second end of the first support member, a second support member including a first end portion, a second end portion and an intermediate section supporting a second axle receiver, a third bellows mounted to the first end portion of the second support member, a fourth bellows mounted to the second end portion of the second support member, a first drive unit including a first transmission mounted to the first support member, and a first electric motor connected to the first transmission, and a second drive unit including a second transmission mounted to the second support member, and a second electric motor connected to the second transmission.

A trailer for towing by a power vehicle is provided and generally includes a frame and a tandem wheel assembly. The frame forms an undercarriage chassis which the tandem wheel assembly is positioned there under. The undercarriage chassis includes a rear wheel assembly, a front wheel assembly, and an extension assembly moving the front wheel assembly between trailing position and a self-propelled position where the rear wheel assembly and the front wheel assembly are positioned to equally support the undercarriage chassis.

A drivetrain system includes a first drive gear driven by a first motor and a second drive gear driven by a second motor. The first drive gear and the second drive gear are arranged along the axis. The first drive gear includes a first extension and the second drive gear includes a second extension arranged radially within and axially overlapping the first extension. The drivetrain system includes a system of bearings arranged between the first drive gear and the second drive gear, either drive gear and a stationary component, or a combination thereof. In some embodiments, the drivetrain system includes a clutch assembly arranged between the first drive gear and the second drive gear that interfaces to the first drive gear and to the second drive gear. The clutch assembly allows the drive gears to be locked or otherwise engaged to improve torque transfer.

A transmission for an at least partially electrically driven vehicle includes two electric machines which are rotationally driveable in a first direction and in a second direction. The transmission further includes an output shaft at least indirectly operatively connected to the first and second electric machines, a first freewheel clutch that at least indirectly transmits a drive power of the first electric machine to the output shaft with a first ratio when the first electric machine rotates in the first direction, and a second freewheel clutch that at least indirectly transmits the drive power of the first electric machine to the output shaft with a second ratio when the first electric machine rotates in the second direction. Additionally, the transmission includes at least one first gear stage in power flow between the first or second freewheel clutch and the output shaft to rotate the output shaft in a third direction.

An electric vehicle transmission (7) includes an input shaft (10), an output shaft (11), a first planetary gear set (P1), a second planetary gear set (P2), and a third planetary gear set (P3). The input shaft (10) is provided for coupling to an electric machine (6). A first shift element (A), a second shift element (B), and a third shift element (C) are provided at least functionally as well. Also disclosed is a drive system (4), a vehicle drive train (5), and an electric vehicle.
