The invention relates to a three-wheeled electric vehicle (10) comprising a front-axle device (22) having two steerable front wheels (24a, 24b) which are aligned substantially parallel to each other when traveling straight ahead; a rear-axle device (12) with a driven rear wheel (14); and a vehicle frame (26) on which the front-axle device (22) and the rear-axle device (12) are supported; wherein the front-axle device (22) is designed such that when the steering angle is rotated, the vehicle frame (26) and the front wheels (24a, 24b) may be tilted in the direction of the rotated steering angle. The compactness value KW, which is calculated from the ratio of the distance SP between the front wheels (24, 24B) when arranged substantially parallel to each other for a straight-ahead travel to the wheelbase RS between the front wheels (24a, 24b) and the rear wheel (14), said wheelbase being measured when the front wheels (24, 24b) are positioned for a straight-ahead travel, satisfies the following condition: KW=SP/RS 0.35≤KW≤0.80, in particular 0.62≤KW≤0.78.

An autonomous tilting three-wheeled vehicle comprises a pair of front wheels coupled to a tiltable chassis by a mechanical linkage, such that the pair of wheels and the chassis are configured to tilt in unison with respect to a roll axis of the chassis. An electronic controller of the autonomous vehicle controls a tilt actuator to selectively tilt the chassis. Optionally, a steering actuator is coupled to the front wheels and controlled by the electronic controller to selectively steer the wheels. A sensor configured to measure orientation-dependent information may be coupled to the chassis by a gimbal configured to compensate for vehicle tilt. In some examples, the autonomous vehicle comprises an autonomous delivery robot.

A three-wheeled vehicle is disclosed having a vehicle frame supported by front ground engaging members and a single rear ground engaging member. The vehicle includes an engine positioned forward of an operator area and a swing arm coupled to the single rear ground engagement member. The operator area of the vehicle may include seating for a driver and a passenger.

A μSMET platform system for ferrying supplies to soldiers in combat, evacuating the wounded, and helping transport loads. The μSMET platform system can adjust its geometry to suit specific payloads and adapt to the terrain, is light enough to be carried by a soldier and sturdy enough to evacuate a soldier, and has adequate off-road mobility to follow an infantry unit. The μSMET platform system's variable geometry enhances mobility over challenging terrain: its rear wheel assembly can expand to increase its stability or contract to reduce its profile.

A magnetic crawler configured to navigate on and inspect a ferromagnetic cylindrical surface is provided. The crawler includes a chassis, a controller configured to control the crawler, a probe configured to inspect the cylindrical surface under the control of the controller, and only three articulated magnetic wheels configured to tangentially contact and magnetically adhere to the cylindrical surface. The wheels include two drive wheels respectively coupled to the chassis by two articulation joints and configured to drive the crawler in a desired direction on the cylindrical surface by actively rotating the two drive wheels independently about respective drive axes of rotation by respective drive motors under the control of the controller; and a rear wheel coupled to the chassis by a rear articulation joint and configured to passively rotate about a rear drive axis of rotation in response to the active rotations of the two drive wheels.

The invention relates to a work machine (1, 1.1, 1.2) comprising: a work unit (2, 2.1, 2.2) or a receptacle (16) for a work unit, exactly one primary vehicle axis (3), wheel elements (4) arranged on both sides of the primary vehicle axis (3), drive units associated with the wheel elements (4), at least one control, wherein the control comprises at least one control circuit and effects a self-balancing of the work machine (1, 1.1, 1.2) about the main vehicle axis (3), and a counter-weight (5), wherein a position of the counter-weight (5) relative to the primary vehicle axis (3) is controllable via the control, and therefore the work machine (1, 1.1, 1.2) can be balanced about the primary vehicle axis (3) and controlled in the movement directions thereof via a position shift of the counter-weight (5).

A method for operating an industrial truck having three wheels. During longitudinal travel, two steerable wheels run in succession in a first lane, and a third wheel runs in a second lane. The third wheel initially runs on an inside during a turning in while cornering until the industrial truck, during a further turning in, transitions into a revolving motion. The method includes reducing a drive power as of a specific steering angle during the turning in prior to the revolving motion, and disengaging or reversing a direction of a drive rotation of the third wheel after a delay time which begins with the reducing of the drive power, or, continuously reducing the drive power from the specific steering angle during the further turning in, and disengaging or reversing the direction of rotation of the third wheel when transitioning into the revolving motion.
