ABSTRACT:
A go-cart vehicle, made from high strength, molded engineering plastics, has a steering shaft tilt assembly which includes a steering shaft (66) slidable in a pivot bushing (70) carried by a bracket (73). The shaft pivots at a U-joint (78) and the bracket (73) pivots at its base. The bracket carries a detent--a cylinder (94) attached to the base (74) of the bracket (73). The cylinder (94) has a number of holes (93) to engage a latch pin (92) which is controlled by a release lever (95) operated by a release button (102). The shaft (66) may be adjusted to varying angles of tilt by moving the latch pin from hole to hole which motion causes the bushing, shaft and bracket to pivot in unison as the shaft slides in the bushing. The vehicle combines a change in caster angle (12) to about 12 degrees with a short, rigid chassis (2) and a live axle (45) to make it possible to turn a sharp corner at speeds of 20 mph or less. The engine (4) is positioned at the lateral midpoint of the vehicle and a crankshaft extension (21) is employed. The power train includes a drive ring (34) that directly engages the wheel spokes (38) by means of an integrally molded, toroidal boss (36) provided with grooves (37) mating with the spokes (38) to drive the same. A one-piece unitary wheel (111) wherein the tire (112) is fitted on a flat rim (115) of the wheel (111) molded of plastic, which rim (115) is then completed with an ultrasonically welded flange (116) to make the wheel (111), including the tire, a unit that cannot be separated.
