Abstract
Abstract An articulated vehicle includes a forward section and a rear section, each supported by a pair of axially aligned wheels. A transmission is supported by the frame of the forward section and is connected to drive the wheels of both sections. A motor is mounted on the transmission rearwardly of the vehicle seat. A bracket is pivotally supported on a generally vertical pivot between two vertically spaced bracket plates on the rear of the front section. A generally horizontal sleeve is supported by the bracket and extends through the front of the frame of the rear section to pivotally connect the two sections.
