  • Patent number: 7952305
    Abstract: A vehicle comprising a rotatable wheel (e.g., three rotatable wheels), a forward drive mechanism including a forward drive motor (e.g., an internal combustion engine), and a reverse drive mechanism. The reverse drive mechanism includes a reverse drive motor (e.g., an electric motor) adapted to move the chassis in the rearward direction, and a reverse drive control programmed to inhibit operation of the reverse drive mechanism when the forward drive motor is off. In one embodiment, the vehicle includes a battery for operating the reverse drive motor, and the reverse drive control is programmed to inhibit operation of the motor when a characteristic of the battery (e.g., an output voltage) falls below a threshold. The vehicle can further include a temperature sensor for the reverse drive motor. In this embodiment, the reverse drive control is programmed to inhibit operation of the reverse drive motor when the temperature of the motor exceeds a threshold.

  • Patent number: 7770683
    Abstract: A three-wheeled vehicle includes a main frame assembly having a steering head disposed on a front portion of the main frame assembly, a front fork assembly pivotably coupled to the steering head, a front wheel rotatably supported by the front fork assembly, a rear frame coupled to a rear portion of the main frame assembly, a rear axle assembly coupled to at least one of the main frame assembly and the rear frame, a pair of rear wheels rotatably supported by the rear axle assembly, an engine-transmission assembly supported by the main frame assembly and positioned between the front wheel and the pair of rear wheels, and a body including a first mounting portion directly mounted to the main frame assembly, and a second mounting portion directly mounted to the rear frame.
