Hydrodynamic from Voith Turbo Turbo
Solutions
100 Years of Hydrodynamics – Anniversary of a Revolutionary Principle The hydrodynamic principle revolutionized technology and turned Voith Turbo Turbo into a worldwide leading company. company. For the first fi rst time it became possible to transmit power wear-free and to realize a completely new form of drive technology: efficient, long-lasting and with unlimited application possibilities. And this has not changed even after 100 years – on the contrary. contrary. All the more mor e reason to t o celebrate this anniversary in style.
1905
Föttinger-Patent
Hermann Föttinger develops the Föttinger Transformer and with it the idea of transmitting mechanical power by fluid virtually wear-free and converting the power factors torque and speed steplessly – the hydrodynamic principle is born.
1927
Voith Schneider® Propeller
Ernst Schneider develops a worldwide unique marine drive which generates thrust steplessly, precisely and fast into all directions.
1930
Herdecke Coupling
Delivery of the first clutch coupling for the drive of the storage pumps at Herdecke hydro power station. To date, over one million Voith turbo couplings have been delivered to customers all over the world.
1933
First Turbo Transmission
Development of the turbo transmission for rail vehicles. To date, approximately 40 000 transmissions have been delivered.
1947
Turbo Coupling with Delay Chamber
The development of the delay chamber and the storage chamber makes it possible for constant-fill turbo couplings to start larges masses even more smoothly with improved characteristic curves.
1949
DIWA® Transmission
The Voith DIWA bus transmission with its unparalleled differential converter is introduced to the experts.
1950
Industrial Converter
Voith now also develops and builds torque converters with guide blade adjustment for industrial applications. Voith Water Tractor
A revolutionary ship’s concept which is particularly effective as it incorporates the Voith Schneider ® Propeller.
1952
Variable-speed Couplings
Development of the Voith variable-speed turbo coupling – its trademark is a radially adjustable scoop tube for direct control of the filling level. It allows dynamic and stepless speed control, for example in pumps, fans and in energy generation.
1954
Geared Variable-speed Couplings
Voith develops the first geared variable-speed couplings. They combine a hydrodynamic variable-speed coupling with a gear stage in a common housing. Flow-controlled TP Clutch Coupling
The first flow-controlled clutch couplings are built.
1961/1965
Hydrodynamic Brake for Rail Applications
First hydrodynamic brake in heavy diesel locomotives. Turbo Reversing Transmission
Voith delivers the first turbo reversing transmission for shunting locomotives.
1965
Retarder
The first retarder marks the triumphant success story of wear-free brakes which operate on the basis of the hydrodynamic principle for coaches and trucks.
1973
Constant-fill Turbo Coupling with Operating Medium Water
Voith Turbo develops the constant-fill turbo coupling using water instead of oil as an operating medium. Especially in mining applications, this innovation by Voith Turbo offers safety and environmental friendliness.
1978
Gas Turbine Starter
The torque converter conquers a new application area as a starting device for gas turbines – more than 3 500 gas turbines from all renowned manufacturers in the world have been started reliably ever since.
1984
Constant-fill Coupling Type TVVS
Voith Turbo is again the trendsetter. The turbo coupling type TVVS with an annular chamber in addition to the delay chamber allows start-up characteristics that had previously been impossible for constant-fill couplings. Belt conveyor drives are the main application area.
1986
Multi-circuit Variable-speed Drive Vorecon ®
The Vorecon – an intelligent combination of mechanics and hydrodynamics. The power-split principle allows very high efficiencies in the range from 1 000 kW to up to 50 000 kW. Today the Vorecon is mainly used as a compressor drive in the oil and gas industry, on and off-shore.
1998
Variable-speed Turbo Coupling with Operating Medium Water
For the first time, a variable-speed turbo coupling operates with the medium water. Fill-controlled Coupling TPKL
Fill-controlled coupling innovation with direct filling and draining cycle
2000
Vosycon
The Vosycon is introduced to the market. A torque converter with integrated lock-up device for starting large compressors, especially in LNG plants. For outputs of up to 250 MW – another impressive innovation by Voith Turbo.
2000
Turbo Transmission
Voith Turbo builds the most powerful turbo transmission to date – the L 620 reU2 – for applications in heavy mainline locomotives.
2002
Aquatarder®
Braking with water for road vehicles? What had not been possible so far, is now a reality with the Voith Turbo Aquatarder, the first of its kind in the world. It uses the cooling water of the engine as an operating medium.
2002
TPL-Syn
New output ranges of up to 10 MW for start-up couplings are possible with the TPL-Syn. It is a combination of a fill-controlled coupling and a mechanical clutch. It combines load-free motor run-ups with smooth start-ups of the driven machine, as well as nominal operation without slip.
2002
DIWA®.5
The further development of the DIWA transmission reaches a new stage: At the IAA, Voith Turbo introduces the DIWA.5 transmission. Voith-Powerpack
Railpack ® goes into series production. The first application takes place in the Minuetto railcar in Italy.
2003
Subsea Converter
A variable torque converter especially for underwater systems. Application: controlling multi-phase pumps for oil production from of up to 3 000 meters below.
2003
Voith Cycloidal Rudder
A pioneering innovation for shipping: the propulsion and manoeuvering element Voith Cycloidal Rudder (VCR). Voith Turbo Fin
By a rotating drum at the end of a fin, the steering force of a Voith Water Tractor can be increased by up to 20 percent.
2004
TurboSyn
A new generation of constant-fill turbo couplings with mechanical lock-up device, which eliminates slip in nominal operation and therefore increases the economy of single drives considerably.
2005
WinDrive®
A drive concept for the wind energy plants of the future. WinDrive – a variable-speed hydrodynamic transmission – allows particularly efficient utilization of wind power stations. A new field of application for hydrodynamics has been created.
