Transmission System Description and Operation

Transmission System Description and Operation

This 3-shaft transmission has the following advantages:

•	Compact construction

•	Improved smooth-running performance

•	Better shift quality

•	High torque transmission

Location of the Shafts

The following cross-sectional diagram shows the location of the respective shafts in the M32-6 transmission, as per the 3-shaft principle.

•	(1) Upper main shaft

•	(2) Input shaft

•	(3) Lower main shaft

•	(4) Differential gear

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.

Location of the Gear Wheels

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.

Power Flow in the Individual Gears

The following diagrams shows the flow of power in the individual gears.
