Forward and reverse mechanism and a vehicle having a recession function

摘要

The present invention low-cost manufacturing, with low running costs, (automatic) motorcycles, trike, forward and reverse mechanism for transmitting a positive reversal possible to rotating body a one-way rotary drive from the power source can also be used on a vehicle such as sidecar I provide. Inserting an A planetary gear 7, the planet carrier 6 for fixing the rotation shaft of the planetary gear, the internal gear 4 as an input or output side to mate with the planetary gear, the planetary carrier and the internal gear and the planetary gear and the fitting to the output or input side to a planetary gear mechanism composed of a sun gear 3 Prefecture, the internal gear and the planet carrier is connected to the internal gear and the sun gear stop the rotation of the planetary gears output by rotating integrally with the sun gear rotates forward, characterized in that the output reversed by stopping the rotation of the planet carrier as well as to release the coupling to allow rotation of the planetary gear and It was the configuration of the forward and reverse mechanism. .BACKGROUND
