Gearbox

摘要

A gearbox for a model car, comprising: a housing; an input gear; an output gear; and at least one intermediate gear. The housing provides a support for each of the input gear, the output gear and each intermediate gear; and in which the gearbox has: a first operating configuration where the input gear, the output gear and at least one intermediate gear are supported by the supports and mesh to form a gear train from input gear to output gear through each intermediate gear supported by the supports; and a second operating configuration where the input gear and the output gear are supported on the supports but fewer intermediate gears are supported by the supports, such that the input gear, the output gear and any intermediate gears supported by the supports mesh to form a gear train from input gear to output gear through any remaining intermediate gears.
