GEARBOX WITH A SYNCHRONIZED REVERSE GEAR

摘要

A gearbox-transmission, especially for power vehicles, with synchronized reverse gear, an intermediate-gearwheel providing for the reversal of direction consists of two loose-gearwheels located on the same axis which is beside the input and output shafts, of which the one loose gearwheel engages the input-shaft via a loose-gearwheel and the fixed-gearwheel of one forward-gear, and the other engages the output-shaft via the loose-gearwheel and the fixed-gearwheel of another forward-gear. The two reverse gear loose-gearwheels are connectable with each other by means of a shift-clutch. In this way no additional gearwheels are needed on the input- and output-shaft for the reverse-gear so that the structural length of such a transmission can correspondingly be reduced.
