The F40-6 is a 6-speed manual gearbox. This manual gearbox is an all-synchromesh 3-shaft transmission.
This 3-shaft transmission has the following advantages:
| • | Compact construction |
| • | Improved smooth-running performance |
| • | Better shift quality |
| • | High torque transmission |
The following cross-sectional diagram shows the location of the respective shafts in the M32-6 gearbox, as per the 3-shaft principle.
| • | Upper main shaft (1) |
| • | Input shaft (2) |
| • | Lower main shaft (3) |
| • | Differential gear (4) |
In this transmission angular cone bearings are used for all shafts. These bearings require a certain amount of play and pretension. The required amount of bearing play and pretension is achieved at the production stage by using shims under the angular cone bearing in the transmission housing.
This diagram shows the location of the gear wheels on the respective shaft.
Lower main shaft | Input shaft with 1st/2nd gear | Upper main shaft | |||
1 | 1st gear wheel | 5 | 3rd/5th gear wheel | 8 | 4th gear wheel |
2 | 2nd gear wheel | 6 | 6th gear wheel | 9 | 3rd gear wheel |
3 | 5th gear wheel | 7 | 4th gear wheel | 10 | Reverse gear wheel |
4 | 6th gear wheel | -- | -- | -- | -- |
A particular benefit of this 3-shaft transmission is that the gear wheel for 3rd gear is also used for 5th gear.
The following diagrams shows the flow of power in the individual gears.
The gears of the F40-6 gearbox will be shifted via a cable linkage system.
