Consume less fuel, reduce complexity, increase driving comfort and economy, greater availability, drive down maintenance costs – there are many reasons to choose DIWA from Voith and now there is one more: the DIWA Efficiency Package.
The DIWA package, including the topography-dependent gear-shifting program SensoTop and Stop-Start Technology, proves just how much more efficiency you can get from a drive with a perfectly complementary system. This also applies to traffic concepts with high service frequency such as “Bus Rapid Transit” (BRT), where only the most advanced drive technology is capable of achieving the required efficiency.
A new take on a proven principle: Lower consumption and reduced emissions during operation, less complexity and low- er installation costs for the manufacturer.
The standard shifting program for constant availability of optimum shift points – depending on topography, load condition and acceleration.
A technology which scores high not only in economy and efficiency, but also in high levels of comfort for passengers and drivers alike.
Our Smart Services contribute to significantly increasing driver performance, which can reduce power consumption considerably.
Modern combustion engines are becoming cleaner and more efficient, and this trend is increasing due to the Euro 6 regulations which are now in force in many countries. DIWA.6 from Voith is the answer to these increasing requirements: The redesigned housing reliably helps meet the greater demands with respect to noise emissions. Intelligent start-up management and needs-based reduction of operating pressure reduce consumption by up to 5%.
The needs-based reduction in operating pressure is a signifi- cant benefit of the DIWA.6 system, whereby full operating pressure is only produced if it is actually needed. As a result, transmission efficiency is given a significant boost.
An additional converter design is provided for engines with higher torque. The new design of torsional vibration damper allows shifts at even lower engine speeds. The benefits for you are lower consumption and reduced CO2 emissions.
The redesigned transmission housing has targeted ribbing in specific areas, which reduces vibrations and therefore noise emissions. The optimized operating concept also assists in this area. The DIWA.6 is therefore able to meet the more stringent Euro 6 noise guidelines.
DIWA.6 combines automatic shift in neutral (ANS) with intelli- gent start-up management: It prevents starting against the active service brake. With the optimized ANS function, the transmission can stay in neutral for longer, thus saving on fuel. It also makes starting up on level routes more comfortable, so that the driver can effortlessly join moving traffic.
Allows stepless starting and braking across a speed range where other transmissions require two or three gear shifts. This results in up to 50% fewer gear shifts, higher driving comfort – and significantly lower wear in the driveline.
Flat or steep roads? Heavy or light loads? Where some manufacturers exclusively rely on driving dynamics calculations, the inclination sensor provides additional and precise information about the terrain of the route – so that SensoTop can steplessly adapt the gear-shifting points in any situation – for maximum fuel efficiency.
Depending on the topography and the vehicle operation, SensoTop reduces fuel consumption by 2 % to 7 % compared to conventional gear-shifting programs.
These is savings potential that can significantly reduce your operating costs. At the same time, SensoTop makes an active contribution to a cleaner environment, since CO2 emissions are sustainably reduced.
SensoTop also increases the safety of passengers and drivers: The gear-shifting concept eliminates gear hunting at upward gradients and allows comfortable start-ups.
