Conversion of two wheeled motorcycle to a three wheeled trike configuration

摘要

A kit and method of motorcycle to trike conversion using a mono-coupe style overlay plate on both sides of the rear swing arm and a non-straddle differential design incorporating hollow metal tube axles and high thrust load maximum surface area bearings, the having a differential assembly comprising a non-straddle differential, a frame, and an axle assembly comprising an axle, wherein the non-straddle differential is supported by the axle.

主权项

1. A kit for converting a two-wheeled motorcycle into a three-wheeled motorcycle, comprising:
a differential assembly comprising a non-straddle differential within the differential assembly, an access hole through the differential assembly, and a bearing located proximal to or at the access hole, wherein the bearing is constructed and located such that engine output load is distributed across the bearing; a frame comprising at least two side plates and at least one supporting cross bar connecting the at least two side plates together, whereby the differential assembly is located between the at least two side plates and does not contact either of the at least two side plates; an axle assembly comprising an axle and an axle support tube, wherein the axle is hollow, wherein the axle passes through the axle support tube and extends through the access hole into the differential assembly, and wherein the axle support tube is attached to the frame and the axle is rotatably supported in the axle support tube by a bearing; a drive sprocket attached to the differential assembly whereby rotation of the drive sprocket causes the rotation of the differential assembly; a planetary gear attached to the axle, and a sun gear attached within the differential assembly and operatively connected to the planetary gear, whereby rotation of the differential assembly causes movement of the sun gear, movement of the sun gear causes rotation of the planetary gear, and rotation of the planetary gear causes rotation of the axle; and an axle stub for connecting the axle to the planetary gear, whereby the axle stub fits within the axle and within an access hole in the planetary gear, wherein the non-straddle differential is supported by the axle, and whereby the non-straddle differential runs directly on the axle, and whereby the differential assembly and the frame are placed between an opening left when a stock rear tire of the two-wheeled motorcycle is removed and replaced with the kit.
