Conventional drive systems for buses offer sustainable transition to the future
HEIDENHEIM, GERMANY. To be a key driver of the mobility transformation with groundbreaking drive solutions is an ambitious commitment that Driventic lives up to every single day. Not just as the independent successor to parts of the drive systems division of international technology group Voith – but above all as a specialist for efficient drive technologies in the commercial vehicle segment, innovative driving force, uncompromising trailblazer, and active partner. This position is grounded in a forward-looking, customer-driven product portfolio for buses, trucks and off-highway applications, individually tailored to the respective requirements of manufacturers and fleet operators and in keeping with the company’s guiding principle: ‘Mobility beyond today’.
CEO Dr. Gregor Wiche points out that, alongside the continuous optimization of the VEDS electric drive system, “the company aims to strengthen and grow its strong market position in conventional solutions, to provide customers with as broad as possible a product range and future-proof solutions across both technology domains”. This approach ensures an ideal combination of openness to innovative technologies, established expertise, and state-of-the-art concepts. Because in the commercial vehicle environment, conventional drive systems continue to provide a reliable, efficient, and cost-effective mobility solution. This generally applies wherever a combination of range, performance and availability is required.
Optimum performance even under the toughest conditions
Whether in the city or the countryside, Driventic’s conventional drive systems consistently meet the most stringent quality standards and deliver peak performance even under the toughest conditions – from powerful acceleration in urban traffic to superior staying power on long routes. Mature and innovative technologies ensure maximum availability, increasing the cost efficiency of the entire vehicle fleet – for reliability without compromise.
Especially for buses, the DIWA NXT automatic transmission serves to bridge the technological gap between diesel engines and alternative technologies. Whether for diesel, CNG, HVO, B100 or H2 drives, the figures speak for themselves. Because to date, a total of more than 400,000 city and intercity buses have been fitted with DIWA automatic transmissions. And these numbers are set to increase.
The right gear at the right time
The great benefit of the DIWA NXT is its optimized efficiency. It features seven gears, a frequency inverter, and a secondary retarder. The optional central recuperation unit (CRU) transforms the DIWA NXT into a fully functional 48 V mild hybrid system, improving fuel efficiency, enabling electric-assist functions, and recovering braking energy – in both city and intercity buses.
What’s more, the DIWA NXT offers other practical features like stop-start functionality, coasting, regenerative braking, and boost support. The entire system is developed and manufactured in accordance with the latest automotive standards, including ISO 26262.
Efficient and eco-friendly drive solution
“Ultimately, all these factors make the DIWA NXT the ideal transmission system that is capable of meeting highly diverse requirements across global markets. Furthermore, it is Driventic’s logical response to the steadily growing demand from manufacturers and fleet operators for efficient and environmentally friendly drive solutions,” explains Dr. Wiche. They are perfectly complemented by other products and systems from the Driventic portfolio that are also redefining efficiency and sustainability in the bus sector. These include world-leading air compressors and the highly elastic vibration damper Hydrodamp.
