The general layout for a front wheel drive, three-wheeled vehicle designed for road use with two steerable driven wheels in the front of the vehicle, and the engine located behind the front of the passenger seating. The vehicle layout is designed for optimal stability and traction by the location of the passenger seating, engine or engines, steering and driven wheels.

The present invention describes an enclosed structure to a 3 wheeler vehicle to provide crash-worthiness (i.e. protection in case of vehicular crash). The structure is further integrated into a crash protection system that absorbs and diverts the crash forces away from it's occupants thus reducing chance of injury and harm to its occupants.

A recumbent tricycle assembly for safely and comfortably riding in a reclined position includes a frame having a front portion that is pivotably coupled to a rear portion. A wheel assembly is rotatably coupled to the frame. The wheel assembly includes a pair of front wheels and a rear wheel. A steering assembly includes a left-hand grip bar and a right-hand grip bar. Manipulation of the left-hand grip bar and the right-hand grip bar steers the frame. A seat is positioned between the front wheels and the grip bars such that each of the left-hand grip bar and the right-hand grip bar is accessible to the user when sitting in the seat. A drive assembly mechanically coupled to the wheel assembly rotates the pair of front wheels and the rear wheel. A brake assembly coupled to the wheel assembly halts rotation of the wheel assembly.

A towable off-road vehicle with a towing engagement system for elevating the vehicle whereby, when engaged for towing with a towing vehicle, only certain wheels that are reversibly lockable for steering are engaged with a road surface over which the off-road vehicle is the be moved.

A vehicle is provided. The vehicle includes a wheel arrangement having a pair of front wheels and a back wheel configuration. The vehicle further includes a frame that is coupled to the wheel arrangement and a steering assembly mounted at a front portion of the frame. The vehicle further includes a battery unit that is disposed on a support portion of the frame and a pedal unit that is mounted at a middle portion of the frame. The vehicle further includes a rear carrier that is proximal to the back wheel configuration and configured to support a cargo container. The vehicle further includes a rear suspension that is mounted on a rear portion of the frame in proximity to the back wheel configuration.

A three-wheeled vehicle may include one rear wheel and two front wheels coupled to a tiltable chassis, such that tilting of the chassis causes a corresponding tilting of the three wheels. The tiltable chassis includes a tiltable body coupled to a non-tilting frame by a pair of rotatable joints, such that the tiltable body is configured to rotate relative to the frame. A fore-and-aft connecting beam of the tiltable body extends beneath the frame to accommodate a battery compartment or other storage on top of the frame. A front tower extends upward from a front end of the connecting beam, above the frame, to couple to a tilt linkage and seat post of the vehicle. A rear tower extends upward from a rear end of the connecting beam to retain the rear wheel.

A wheel hub assembly for a vehicle includes a shaft adapted for operatively connecting to a motor of the vehicle. The shaft including a threaded end portion, and a splined portion including a plurality of external splines; an integral braking hub disposed on and connected to the shaft; a wheel fastened to the integral braking hub by a plurality of fasteners; and a nut fastened to the threaded end portion of the shaft, the wheel being disposed between the nut and the brake disc portion in an axial direction of the shaft. The integral braking hub includes a central hub portion including a plurality of internal splines and a brake disc portion extending radially from the central hub portion, the brake disc portion being integral with the central hub portion and the central hub portion or the brake disc portion defining a plurality of through-holes.

A vehicle configured to operate in a normal steering mode and a differential steering mode is disclosed. The vehicle includes at least three wheels with the first and second wheels disposed on opposite sides of the vehicle. First and second motors, independently controllable by a motor control unit, drive the corresponding wheels. A steering shaft connects a steering mechanism for changing the angle of travel of at least one wheel to a steering wheel, when the vehicle operates in the normal steering mode. When the vehicle operates in a differential steering mode, a steering lock mechanism locks the at least one wheel in a fixed angle of travel, and a sensor senses the direction the steering wheel is turned. The motor controller causes the motor to rotate the first and second wheels at different rotational speeds to turn the vehicle the direction the steering wheel is turned.
