Product Description
• Hydrodynamic coupling
section „Functioning principle of the hydrodynamic coupling“, page 18
Changing over the
hydrodynamic
circuits
The transmission control switches automatically from one hydrodynamic circuit to an-
other, depending on the vehicle speed and engine load stage. The torque converter is
filled in the lower speed range and the hydrodynamic coupling is filled in the upper
speed range. There is no interruption in traction during the changeover process.
Power transferPower in the turbo transmission is transmitted in the filled circuit by the mass forces of
the operating fluids (power transmission oil). The projected traction is only achieved
once the power transmission oil reaches operating temperature.
Once the traction command is issued, it may take a second before the hydrodynamic
circuits on the turbo transmission are filled.
Power transmission
oil
Apart from transferring power, the oil in the turbo transmission is also used for lubri-
cating, cooling and controlling the turbo transmission. Because the power transmis-
sion oil in the turbo transmission has to meet very stringent requirements, only power
transmission oils approved by Voith may be used.
Waste heatWaste heat is generated in traction mode. This heat is dissipated by the coolant circuit
on the diesel engine.
Pumps
Primary endThe following pumps are connected to the primary end:
• Filler pump for the hydrodynamic circuits
The filler pump supplies power transmission oil to all hydrodynamic circuits and lu-
brication points.
• Control oil pump
The control oil pump supplies power transmission oil to the control lines.
Secondary endThe following pumps are connected to the secondary end:
• Lubricating pump
The lubricating pump supplies power transmission oil to the lubrication points.
Electrical components
The following electrical components are used:
• Sensors
• Actuators
• Wiring
• Plug connections

3.3.2 Functioning Principle of the Main Components
Functioning principle of the torque converter
The diesel engine drives pump impeller 1 via the step-up gear. The mechanical en-
ergy generated by the diesel engine is converted into hydrodynamic energy in the
power transmission oil.
Adjacent turbine wheel 2 harnesses the hydrodynamic energy by decelerating and re-
directing the power transmission oil and converts it back into mechanical energy.
The torque produced in the turbine wheel depends on the volumetric flow, degree of
redirection and speed of the power transmission oil. The turbine torque reaches its
peak when the turbine is not running and decreases with increasing turbine speed.
The power consumption of the pump impeller is only slightly influenced by the respec-
tive turbine speed.
Guide wheel 3 has the task of optimising and maintaining a constant supply direction
to the pump impeller regardless of the output flow direction at the turbine wheel. The
guide wheel absorbs the torque differential between the pump impeller and the turbine
wheel and thereby achieves the torque conversion.

Product Description
Functioning principle of the hydrodynamic coupling
The diesel engine drives pump impeller 1 via the step-up gear. The mechanical en-
ergy generated by the diesel engine is converted into hydrodynamic energy in the
power transmission oil.
Adjacent turbine wheel 2 harnesses the hydrodynamic energy by decelerating and re-
directing the power transmission oil and converts it back into mechanical energy.
The pump torque and turbine torque for a hydrodynamic coupling are identical.
Functioning principle of the reversing unit
The reversing unit consists of a hydraulically actuated reversing cylinder and accom-
panying sliding shaft.
Direction of rotation
A or B
The reversing cylinder meshes the corresponding gear wheels for the selected direc-
tion of rotation. The mechanical energy can be transferred to the output shaft.

Product Description
The reversing unit is electronically activated and monitored by the transmission con-
trol. The various operating conditions that arise during the reversing process are mon-
itored by different sensors.
3.4 Flow of Power in the Turbo Transmission
The fully automatic turbo transmission measures the input speed of the diesel engine
and transfers the corresponding output speed to the transmission output drive de-
pending on the operating conditions.
The torque of the diesel engine is transferred to the drive shaft on the turbo transmis-
sion via a torsional vibration damper.
The gear wheel on the drive shaft transfers the torque to the toothed primary shaft on
the turbo transmission via the step-up gear.
The following are fastened to the primary shaft:
• Torque converter pump impeller
• Hydrodynamic coupling pump impeller
The torque resulting at the turbine wheel when the torque converter or hydrodynamic
coupling is filled is transferred to the output drive via the secondary shaft.
The following are fastened to the secondary shaft:
• Torque converter turbine wheel
• Hydrodynamic coupling turbine wheel
• Hydrodynamic brake rotor
When the hydrodynamic brake is filled, the adjustable braking torque acts on output
drive via the rotor.
The direction of rotation of the output flange depends on the position of the sliding
shaft in the reversing unit.
• Direction of rotation A:
Output direction of rotation identical to input direction of rotation
• Direction of rotation B:
Output direction of rotation opposite to input direction of rotation

weight of the turbo transmission including attachments.
The lifting eye bolts on the turbo transmission are only designed to bear the total
weight of the turbo transmission without attached parts. If the total weight of the turbo
transmission increases as a result of attached parts, these lifting eye bolts can only
be used after consulting Voith.

5.3 Installing the Turbo Transmission
5.3.1 Transmission Suspension
Rubber elements are used for statically determinate suspension of the turbo transmis-
sion in the main frame of the rail vehicle.
This type of transmission suspension with rubber elements reduces the transfer of
structure-borne sound and vibrations from the turbo transmission to the main frame.
The turbo transmission must be installed by competent personnel from the vehicle
manufacturing company in accordance with the manufacturer's instructions.
Observe the following in addition to the existing operating instructions:
Outline drawing, register 2
Any modifications, attachments oder conversions of the turbo transmission must not
be implemented without approval from Voith.
NOTICE
The turbo transmission may be damaged if dirt enters the turbo
transmission or moisture condenses on the mounting surfaces.
Only unpack the turbo transmission directly before installation in the vehicle.
Only remove the plastic caps and adhesive tape directly before connecting
pipelines.
