A leaning vehicle, including a vehicle body, one steerable front wheel and two rear wheels, or two steerable front wheels and one or two rear wheels, a suspension mechanism, a steering mechanism, a steering controller, and an up-down direction acceleration detector attached to the vehicle body or the suspension mechanism. The two steerable front wheels or the two rear wheels are arranged side by side to form a left-right pair of wheels. The up-down direction acceleration detector detects an acceleration in an up-down direction of the leaning vehicle or the vehicle body, generated as one wheel in the left-right pair of wheels passes a bump or a pothole in a road. The steering controller so controls the one or two steerable front wheels that the one or two steerable front wheels are in a free-steering state, so as to swivel around a steering axis freely, based on the detected acceleration.

A three-wheeler including two front wheels and a rear wheel, left and right seats, a steering mechanism steering the front wheels, an electric motor generating a torque by electrical energy, a power transmission mechanism transmitting the torque to the front wheels, and a body frame. A center of gravity of the three-wheeler is more frontward than a front end of the two seats and than a middle point of the wheelbase, and is more rearward than a front end of the electric energy storage device. The seats is, in a top view, partially in a triangle area that has a center of each of the front wheels and the rear wheel as vertices. The electric energy storage device, in the top view, overlaps a foot-resting area and is partially in the triangle area. The electric energy storage device is between the two front wheels.

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; a steering wheel configured to control the turn of the rear wheel when the front wheels are set to the narrow track; track width control 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 braking that front wheel.

A rear suspension for a three-wheeled reverse trike includes a front lever arm pivotably affixed to a frame pivotable about a front lever arm pivot axis. A slider is translatably attached to the front lever arm. A first pushrod is pivotably connected at a first end to the slider and pivotably connected at a second end to at least one of a front upper or lower control arms for the front wheels. A rear lever arm is pivotably affixed to the frame and pivotable about a rear lever arm pivot axis, the rear lever arm extending to a rear lever arm distal end. A rod pivotably connects the front and lever arms. A first pivotable end of the rear upper control arm is pivotably connected to the rear lever arm distal end, and a second pivotable end of the rear upper control arm is pivotably connected to a rear spindle.

The general layout for a front wheel drive, three-wheeled vehicle with two steerable driven wheels in the front of the vehicle, and the motor or motors located in the mid-section of the vehicle. The vehicle is designed for compact motors, in-hub motors, and direct connect motors which allow a significant portion of the vehicle's weight to be moved forward, while integrating location of the passenger seating, steering, and driven wheels allows for a highly stable vehicle. The layout maintains the traditional bucket or bench style seats as found in today's automobiles, and yet allows for weighting and cockpit adaptability for different market demographics.

A three-wheeler including two front wheels and a rear wheel, left and right seats, a steering mechanism steering the front wheels, an electric motor generating a torque by electrical energy, a power transmission mechanism transmitting the torque to the front wheels, and a body frame. A center of gravity of the three-wheeler is more frontward than a front end of the two seats and than a middle point of the wheelbase, and is more rearward than a front end of the electric energy storage device. The seats is, in a top view, partially in a triangle area that has a center of each of the front wheels and the rear wheel as vertices. The electric energy storage device, in the top view, overlaps a foot-resting area and is partially in the triangle area. The electric energy storage device is between the two front wheels.

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.

A leaning vehicle, including a vehicle body, one steerable front wheel and two rear wheels, or two steerable front wheels and one or two rear wheels, a suspension mechanism, a steering mechanism, a steering controller, and an up-down direction acceleration detector attached to the vehicle body or the suspension mechanism. The two steerable front wheels or the two rear wheels are arranged side by side to form a left-right pair of wheels. The up-down direction acceleration detector detects an acceleration in an up-down direction of the leaning vehicle or the vehicle body, generated as one wheel in the left-right pair of wheels passes a bump or a pothole in a road. The steering controller so controls the one or two steerable front wheels that the one or two steerable front wheels are in a free-steering state, so as to swivel around a steering axis freely, based on the detected acceleration.

An antilock brake system is disclosed comprising a first wheel and second wheel disposed on opposite sides of a vehicle. A first electric motor providing torque to the first wheel and a second electric motor providing torque to the second wheel. A sensor monitoring each wheel and a brake on each wheel. A system is described wherein a processor monitors signals from the sensors and increases torque to either wheel when it detects that the wheel is not rotating when another wheel is rotating. Also disclosed is an antilock brake system as above with a third wheel disposed on the rear of the vehicle also comprising a sensor and brake on the third wheel and wherein the processor monitors signals from the sensors to increase torque to either front wheels when it detects that the wheel is not rotating when another wheel is rotating.
