TRANSMISSION 722.6 in MODEL 163, 170, 202, 208, 210 with touch shift
TRANSMISSION 722.6 in MODEL 215, 220, 240
Transmission 722.6 is an electronically controlled 5-speed transmission with a lockup clutch in the torque converter. The ratios for the gear stages are achieved by 3 planetary gearsets. The 5th gear is designed as a low-rev gear with an overdrive ratio.
Shifting is initiated electronically. The gears are shifted by the corresponding combination of 3 hydraulically actuated multi-disk brakes, 3 hydraulically actuated multi-disk clutches and 2 mechanical freewheels.
Basically transmission 722.6 with electronic control offers the following advantages:
- Reduced fuel consumption
- Greater ease of shifting
- Favorable spacing by 5 gears
- Long service life and high reliability
- Low maintenance costs
The torque converter housing and transmission housing consist of a light-metal allow. Both housings are bolted together and are centered via the external plate carrier of the multi-disk brake at the front. A coated intermediate panel seals the two components.
The oil pump as well as the external plate carrier of the front multi-disk brake are bolted to the torque converter housing.
The mechanical part of the transmission 722.6 consists of a drive shaft, output shaft, a sun gear shaft and 3 planetary sets which are coupled to each other.
The electrohydraulic control unit is screwed onto the transmission housing from below. The end of the transmission is formed by an oil pan made of sheet steel.
The oil pressure of the torque converter lockup clutch and center multi-disk clutch is supplied via bore holes in the drive shaft. The oil pressure to the rear multi-disk clutch is supplied via the output shaft. The lubricating oil is supplied and distributed by additional bore holes in both shafts. Oil is supplied to all bearing points of the gearsets as well as to the freewheels and shifting elements.
The parking lock gear and drive flange are connected to the output shaft by gearing.
Freewheels F1 and F2 optimize shifting. The front freewheelF1 is supported on the extension of the stator shaft on the transmission end and connects in the locking direction the sun gear of the front planetary gearset with the transmission housing.
The rear freewheel F2 connects in the locking direction the sun gear of the center planetary set with the sun gear of the rear planetary set. The electrohydraulic control unit is comprised of a light alloy shift plate for the hydraulic control and an electric control unit.
The electronic control unit consists of a plastic shell which combines all the electric components. The shell is mounted on and bolted to the shift plate. Conductor tracks which are laid in the supporting body make the connection between the electrical components and a 13-pin plug socket.
