Abstract
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.
Claims5
A gearbox-transmission for motor vehicles, comprising:
- a first shaft;
- a second shaft arranged in parallel to the first shaft;
- a first gearwheel fixed to the first shaft;
- a second gearwheel rotatably mounted to the second shaft and engaging the first gearwheel;
- means for fixing the second gearwheel to the second shaft to provide a first forward gear;
- a third gearwheel rotatably mounted to the first shaft;
- a fourth gearwheel fixed to the second shaft and engaging the third gearwheel;
- means for fixing the third gearwheel to the first shaft to provide a second forward gear;
- a third shaft arranged in parallel to the first shaft;
- a fifth gearwheel rotatably mounted to the third shaft and in driving connection with the first gearwheel;
- a sixth gearwheel rotatably mounted to the third shaft and in driving connection with the fourth gearwheel;
- and
- means for connecting the fifth gearwheel and the sixth gearwheel to provide a reverse gear.
