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.

A vehicle having a front axle with a pair of front wheels having a track width adjustable between a wide track and a narrow track; a rear axle with at least one rear wheel; steering means configured to control the turn of the rear wheel when the front wheels are set to the narrow track; track width control means configured to change the track width of the front wheels and to change the wheel base between the front axle and the rear axle such that for the wide track of the front wheels the wheel base is longer than for the narrow track of the front wheels; a locking mechanism configured to lock the track width; wherein each of the front wheels is connected to a dedicated front wheel motor for driving that front wheel and to a dedicated front wheel brake for breaking that front wheel.

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.

An aerodynamic vehicle includes an aerodynamic heat exchanger formed as one or more body panels disposed along an outer surface of the vehicle having one or more fluidic chambers or micro-channels. The aerodynamic heat exchanger is adapted to provide effective and highly efficient heat transfer, and also to provide substantially reduced or negligible contribution to the aerodynamic drag. The aerodynamic heat exchanger may provide adequate heat rejection capacity throughout vehicle operating conditions that advantageously results in increased fuel economy and overall vehicle performance.

Providing a movement control means for detecting a collision between a driving wheel and a step and a catch of a driven wheel by the step and temporarily changing a gravity center control region of a mobile device and moving the mobile device to pass over the step, and a mobile device including the same in order to prevent immovability under an environment having a step or an irregularity. Thus, a mobile device is configured to include: a lower body; an upper body provided in an upper portion of the lower body; a gravity center position adjustment means for changing an angle or a position of the upper body with respect to the lower body; and a driving wheel and a driven wheel provided in a lower portion of the lower body, and during movement in a direction in which the driving wheel is on a front side and the driven wheel is on a rear side, the gravity center position adjustment means inclines or moves the upper body to the front side when the driven wheel passes over the step, and moves the upper body toward an original angle or position after the driven wheel passes over the step.

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 three-wheeled automobile is described herein. The automobile may include a unibody frame, a flexible engine cowling, and a fastener. The unibody frame may include an exposed unibody panel and/or a removable-panel securing fixture disposed adjacent to the exposed unibody panel. The engine cowling may be secured to the securing fixture. The fastener may pass through the engine cowling panel and may be affixed to the securing fixture, thereby securing the engine cowling panel to the unibody frame. The engine cowling panel may pass over the securing fixture and/or behind the unibody panel. The engine cowling panel may be pressed against the unibody panel outwards from the automobile by a bending force in the engine cowling panel such that the exposed unibody panel may prevent bowing of an outside edge of the engine cowling panel directly adjacent to the unibody panel.

A right shock absorber and a left shock absorber are provided on outer sides of a left front wheel and a right front wheel that define a steering allowable space therebetween. At a lower portion of the right shock absorber, an outer edge of a right front fender is positioned farther radially outwards than an outer edge of the right front wheel, and a right guide wall that extends from the outer edge inwards is provided in an upper rear area to the left of the right front wheel. At a lower portion of the left shock absorber, an outer edge of a left front fender is positioned farther radially outwards than an outer edge of the left front wheel, and a left guide wall that extends from the outer edge inwards is provided in an upper rear area to the right of the left front wheel.

A scooter includes a front platform and a driver platform rotatably connected to each other and each having a planar surface. Wheels are rotatably connected to the front platform and the driver platform, and a motor is in at least one of the wheels. The front platform and the driver platform are relatively rotatable between a stowed position in which the planar surfaces are in separate planes and a cargo position in which the planar surfaces are coplanar.

A narrow track tilting vehicle includes an undercarriage centered over a contact point, an upper chassis configured to pivot about a mobile longitudinal axis, and a cradle assembly configured to allow the mobile axis to move laterally relative to the contact point. In wheeled embodiments, the configuration of the carriage allows the upper chassis to tilt in response to centrifugal forces, while allowing the wheels to remain perpendicular to a level surface along which the vehicle is traveling. When the vehicle is traveling along a surface that is canted relative to the level surface, the configuration of the carriage allows to the upper chassis to remain upright relative to the level surface, and the wheels to extend perpendicular to the canted surface.
