Abstract

A two-wheel drive motorcycle having an electric motor driving the front wheel, an embodiment of the present invention, in addition to a conventional rear wheel drive train. The front wheel drive disclosed herein may be adapted to conventional telescoping (or shock-absorbing) front fork suspension systems. The front wheel drive of the two-wheel drive motorcycle may be applied to a number of different types of motorcycles including motocross, enduro, dual-sport and touring motorcycles.

Claims

1. An electric powered front wheel drive system for a motorcycle having a conventional or other rear wheel drive train, comprising:

an electric motor integrated into the front wheel hub;

said electric motor'"'"'s wires (cable) are routed up the front suspension forks to a controller mounted near the front of the motorcycle;

said controller comprises hardware and software which receives feedback signals from many sensors, receives power from a battery, and outputs power to the electric motor;

said controller receives power from a battery near the rear of the motorcycle.

2. The front wheel drive system for a motorcycle defined in claim 1, wherein said controller'"'"'s feedback signals from sensors may include, but are not limited to, throttle demand (position), front brake demand (position or pressure), rear wheel speed, volts, amps, or driver inputs to an instrument panel.

3. The front wheel drive system for a motorcycle defined in claim 1, wherein said controller regulates the power to the electric motor based on rear wheel slip, and or throttle demand, and or brake demand.

4. The front wheel drive system for a motorcycle defined in claim 1, wherein said controller may reduce or eliminate the fly-wheel effect by using accelerometers to detect when the motorcycle has left the ground (now airborne), then reducing power to the front wheel electric motor.

5. The front wheel drive system for a motorcycle defined in claim 1, wherein said electric motor can act as a generator to re-charge the battery under multiple driving conditions, including but not limited to, braking, coasting, and steady high speeds.

6. The front wheel drive system for a motorcycle defined in claim 1, wherein said battery is not limited to traditional chemical type batteries, but may be a hybrid chemical and super capacitor battery.

7. An alternate embodiment of the invention defined in claim 1, wherein one or two electric motors are mounted on the upper stationary portion of the front telescoping forks. Power is transmitted to the front wheel hub, by mating gears and telescoping spline shafts.
