Narrow three wheeled vehicle with stabilizing and modular mechanisms
A three-wheeled vehicle includes a vehicle frame supported by a single wheel engaging the ground in the front and two wheels engaging the ground in the rear. The operator area of the vehicle may include seating for a driver and a passenger, one in front of the other. The three-wheeled vehicle is uniquely designed so that it can be easily modified by addition or removal of additional structures after it is purchased. The vehicle is ultra-narrow but achieves stability by unique mechanisms.

a chassis having a front portion and a rear portion, the front portion having a front wheel and a driver seat, and the rear portion having a first rear wheel, a second rear wheel, and a rear axle assembly configured to be selectively moved between a retracted position and an extended position to maintain stability at various speeds, the front portion configured to tilt relative to the rear portion about a tilt axis disposed along a length of the chassis, the rear portion including a hollow main body having at least one battery module configured to power a movement of at least one of the front wheel, the first rear wheel, and the second rear wheel, and at least one passenger seat disposed on the rear portion of the chassis behind the driver seat; and
a prime mover of the chassis configured to move the rear axle assembly configured to be selectively moved between a retracted position and an extended position.
2 . The motorized vehicle of claim 1 , wherein a maximum width of the rear axle assembly in the retracted position is about 880 mm and a minimum width of the rear axle assembly in the extended position is about 1280 mm.
3 . The motorized vehicle of claim 1 , further including at least one electric drive motor and an electric drive motor controller, the at least one electric drive motor attached to one of the front wheel, the first rear wheel, and the second rear wheel, and the electric drive motor controller disposed on the front portion of the chassis, the at least one electric drive motor in electrical communication with the at least one battery module, and the electric drive motor controller in electrical communication with the at least one electric drive motor and configured to permit a driver to control the movement of at least one of the front wheel, the first rear wheel, and the second rear wheel.
4 . The motorized vehicle of claim 3 , where the at least one electric drive motor includes a first rear electric drive motor connected to the first rear wheel, and a second rear electric drive motor connected to the second rear wheel.
5 . The motorized vehicle of claim 4 , wherein each of the first rear electric drive motor and the second rear electric drive motor is connected to the rear axle assembly with rubber torsional axle suspension member.
6 . The motorized vehicle of claim 1 , wherein the driver seat is collapsible.
7 . The motorized vehicle of claim 1 , wherein the at least one passenger seat is collapsible.
8 . The motorized vehicle of claim 1 , further comprising a plurality of connection points configured for attachment of bodywork structure to the chassis.
9 . The motorized vehicle of claim 8 , further comprising the bodywork structure attached to the chassis with at least a portion of the plurality of connection points.
10 . The motorized vehicle of claim 9 , wherein the bodywork structure includes a roll cage.
11 . The motorized vehicle of claim 9 , wherein a total length of the motorized vehicle including the chassis and the bodywork structure is less than about 2400 mm.
12 . The motorized vehicle of claim 1 , further comprising a locking mechanism configured to selectively lock the front portion to the rear portion to militate against a tilt of the front portion relative to the rear portion about the tilt axis.
13 . The motorized vehicle of claim 12 , wherein the locking mechanism is a spring-loaded shot pin disposed on one of the front portion and the rear portion of the chassis.
14 . A motorized vehicle, comprising:
a chassis having a front portion and a rear portion, the front portion having a front wheel and a driver seat, and the rear portion having a first rear wheel, a second rear wheel, and a rear axle assembly configured to be selectively moved between a retracted position and an extended position to maintain stability at various speeds, the front portion configured to tilt relative to the rear portion about a tilt axis disposed along a length of the chassis, the rear portion having a hollow main body, and at least one passenger seat disposed on the rear portion of the chassis behind the driver seat;
at least one battery module disposed in the hollow main body of the rear portion configured to power a movement of at least one of the front wheel, the first rear wheel, and the second rear wheel;
a first rear electric drive motor connected to the first rear wheel;
a second rear electric drive motor connected to the second rear wheel;
an electric drive motor controller disposed on the front portion of the chassis, the electric drive motor controller in electrical communication with the first rear electric drive motor and the second rear electric drive motor and configured to permit a driver to control the movement the first rear wheel and the second rear wheel;
