725.0 transmission

The 9-speed automatic transmission 9G-Tronic As a result of 725.0 transmission computer system analysis and synthesis, transmission engineers solved this problem by means of only 4 planetary gear sets and 6 gear shifting mechanisms, 725.0 transmission. No items found matching the search criteria. The span of gear ratios is equal to 9.

V12 engine models continue to use the older Mercedes-Benz 7G-Tronic transmission. By the end of unsurpassed ratio span among longitudinal automatic transmissions for passenger cars. Development took place at the group's headquarters in Stuttgart-Untertuerkheim. Technical and economic progress is reflected in 9 forward gears [a] out of 10 main components, [b] compared to 7 forward gears [c] out of 11 main components [d] in the direct predecessor. It is fully electronic controlled. Torque converter lock-up can operate in all 9 forward gears. These ordinates are positioned on the abscissa in strict accordance with the proportions of the sun gears' teeth numbers relative to those of their rings.

No items found matching the search criteria. The span of gear ratios is equal to 9. Despite two additional gears and the maximum torque up to Nm, 9G-Tronic requires the same amount of space for positioning as its predecessor. Three speed sensors monitor the operation of the gearbox and provide the TCU with relevant information for efficient gear shifting. Three different modes of operation allow the driver to pre-select an appropriate algorithm of gear shifting. It improves driving comfort and reduces the noise level. The 9G-Tronic transmission has 3 driving modes:.

These ordinates are positioned on the abscissa in strict accordance with the proportions of the sun gears' teeth numbers relative to those of their rings. Consequently, the output ratios on the 3rd ordinate carrier of the third planetary gearset follows closely those of the actual transmission. This advantageous geometric construction sets us free from Willis' famous and tedious formula, because all calculations are exclusively determined by lengths ratios, respectively teeth numbers on the abscissa for the 4 epicyclic ratios, and of rotational speeds on the 3rd ordinate for the 10 gear ratios.
