'Driven by Efficiency': Voith Presents Sustainable and Efficient Drive and Braking Systems at Busworld 2015
The new DIWA.6 automatic transmission is Voith's response to the rising demand for clean and fuel-efficient vehicles, especially in the context of the Euro-6 requirements. Specifically developed for citybuses, DIWA automatic transmissions are the best prerequisite for economical operations. Compared with its predecessor model, the DIWA.6 can save almost another five percent fuel. Apart from utilizing the topography-dependent gear-shifting program SensoTop, this is made possible by the need-based reduction of the operating pressure and an intelligent start-up management that avoids starting against the active service brake. With the optimized Automatic Neutral Shift (ANS) function the transmission can stay decoupled from the engine for longer, which also saves fuel. Numerous bus operators in Europe rely on the transmission in demanding inner city traffic.
Braking with Water –
the Aquatarder SWR
At the center of the Voith exhibition appearance at the Busworld is also the Aquatarder SWR that is an energy-efficient, resource-sparing component for buses, coaches and trucks. The Voith Aquatarder SWR is the first secondary retarder to brake with water, using the cooling agent of the engine for the process. This means that it does not need an additional operating medium and is able to perform up to 90 percent of all vehicle braking operations wear-free. In addition, it requires only half the installation space compared with its predecessor and is 35 kg lighter.
DIWA SmartNet: Easy and Efficient Driveline Monitoring
With the Voith-developed telemetric system DIWA SmartNet operators are always optimally informed about the condition of their drivelines. Due to high mileages, difficult climatic conditions and the demand for maximum vehicle availability, classic service and maintenance strategies soon reach their limits. Automated data recording and evaluation create a distinctive added value for operators: maintenance and service routines can therefore be planned much easier, and vehicle availability is increased. DIWA SmartNet is an integrated solution for monitoring the driveline and allows fast and direct access to operating data. With the new generation DIWA SmartNet 2.0, data for transmission diagnosis can now also transmitted via WiFi, which allows significant cost savings compared to the mobile radio solution.
Air Compressor Units for EURO-6 Engines
Voith air compressors shown on the exhibition stand are also suitable for the new EURO-6 engines. Produced with aluminum lightweight design, the two-stage compressors are a series feature of Daimler, MAN and Volvo coaches. Thanks to the two-stage principle, Voith air compressors save up to 1 liters of diesel per
100 kilometers. Since 2012 Voith has produced over 200,000 air compressors at its location Zschopau, Germany.
