ABSTRACT:
A self-propelled, three-wheeled vehicle includes a power-driven single front wheel used also for steering the vehicle and two transversely spaced apart rear wheels. The front wheel is rotatably mounted on a front frame which is pivotally connected to a rear frame to allow steering movement of the front frame. The rear wheels are connected to the rear frame, which supports the rider or riders, by a parallelogram-type balancing linkage which allows the vehicle frames and the rider to lean into turns and also to remain upright when the vehicle passes over or is parked on laterally inclined terrain. The front wheel is driven by one or more hydraulic motors supported by the front frame. Hydraulic pressure to the motor(s) is supplied from an engine-driven pump assembly supported by the rear frame.
