Assembly for increasing motorcycle wheel count

摘要

An assembly for converting a motorcycle from a two wheel vehicle into a three wheel vehicle having alternate left and right side front wheels. The assembly is constructed to cooperate with an underlying motorcycle frame without physically altering the underlying motorcycle frame. The assembly includes a center frame assembly that is securable to the underlying motorcycle frame and which aligns a support tube of the assembly with a passage defined by a head tube of the motorcycle frame. Respective A-arm assemblies are pivotably secured to alternate lateral sides of the center frame assembly and a steering arm is pivotably attached to each A-arm assembly. A tie rod extends inboard from each steering arm to an area bounded by the center frame assembly and operatively cooperates with a steering shaft that passes through the head tube and the support tube to effectuate turning of the left and right side front wheels.

主权项

1. A kit for converting a motorcycle into a three-wheeled vehicle, the kit comprising:
a first A-arm assembly and a second A-arm assembly; a steering arm pivotably connected to one of the first and second A-arm assemblies, respectively; an axle extending in an outward lateral direction from each steering arm, each axle constructed to rotationally support a wheel; a center-frame assembly having each of the first and second A-arm assemblies pivotably connected thereto such that the first and second A-arm assemblies are oriented on opposite lateral sides of the center-frame assembly, the center-frame assembly including a plurality of fore and aft oriented members wherein an aft end of each fore and aft oriented member includes a clamp portion that is shaped to overlap a portion of the motorcycle frame that is proximate thereto; a pair of tie rods each having a first end connected to a respective steering arm and a second end that is positioned within a cavity bounded by the center-frame assembly; and a support tube defined by a generally elongate body having a first end secured to the center-frame assembly and a second end that is oriented to engage a neck of a motorcycle frame, the support tube having a passage formed therethrough that is shaped to receive a steering shaft wherein a first end of the steering shaft is pivotably connectable to each tie rod and a second end of the steering shaft is oriented to extend through the neck of the motorcycle frame when the support tube is aligned with the neck of the motorcycle frame.
