By the direct proportional selection with separate pressure modulation for each clutch, the
pressures to the clutches, taking part in the gear change, are controlled. In this way, a hydraulic
overlab of the clutches to be engaged and disengaged is achieved.
This is leading to fast shiftings without traction force interruption.
At the shifting, the following criteria are considered:
- Speed of engine, turbine, central gear train and output.
- Transmission temperature.
- Shifting mode(Up-, down-, reverse shifting and gear engaging from neutral).
- Load level(Full- and partial load, traction, coasting inclusive consideration of load cycles during the
shifting).
The system pressure valve is limiting the maximum control pressure to 16+2 bar and releases the
main stream to the converter and lubricating circuit.
A converter relief valve is installed in the converter inlet, which protects the converter against high
internal pressures(Opening pressure 9bar).
Within the converter, the oil transfers the power transmission according to the well-known
hydrodynamic principle(See torque converter, page 3-3).
In order to avoid cavitation, the converter must be always completely filled with oil.
This is achieved by a converter back pressure valve, following the converter, with an opening
pressure of about 3.5bar.
The oil, escaping from the converter, is directed to a oil cooler.
The oil is directed from the oil cooler to the transmission and from there to the lubricating-oil circuit
so that all lubricating points are supplied with cooled oil.
In the electro-hydraulic control unit there are 6 pressure regulators installed.
5) GEAR SELECTOR(DW-3)
The gear selector is designed for the
mounting on the left side of the steering
column. The positions(Speeds) 1 to 4 are F
