Gearbox production: Optimization – the eternal quest
”To achieve consistent quality, you need to continuously synchronize customer expectations and your search for optimization potential” said Tomoyoshi Sator, Senior Vice President Corporate Quality Assurance Division, Jatco Ltd. at the 11th CTI Symposium USA in May 2017 in Novi, Michigan. Jatco’s example is another clear reminder that tomorrow’s biggest challenge involves continuously self-optimizing internal processes (particularly in production), not meeting requirements in different markets or achieving breakthroughs in drive system frugality. That means manufacturers need to work out how to ensure consistent quality and efficiency across all international facilities – and also bring new and promising methods into production.

Formula 1 Expert Fritz Indra: The Automotive Sector is Under Pressure.
The automotive sector is under pressure. Aside from all internal trouble a considerable part of the pressure in the industry is caused by legislation, Fritz Indra says. All car manufacturers are currently pushing electrification, which may also be a strategy to take the bull by the horns. But in the opinion of the Austrian engine designer and Formula 1 expert, the current trend towards the electric car should be regarded in a more critical way than it currently is the case. Especially with regard to climate protection, he says, because electric cars aren’t as clean as they are expected to be. Continue reading
CTI Mag: P3 Hybridization of Manual Transmissions
In terms of cost and fuel efficiency, manual transmissions still take a leading position. However, solutions are needed to make them compatible with future ADAS and powertrain hybridization. The GETRAG modular upgrade concept offers a scalable approach, adding automation and electrification on a common MT platform.

CTI Mag: Modification of Surface Structure and Geometry on Gears
Walter Graf, Reishauer AG, Switzerland
Demands placed on today’s automotive transmissions include, among others, low gear noise levels (NHV), weight reduction, fuel economy, increased longevity and high power density. Modify¬ing the surface structures and flank geometry can lead to higher transmission performance in line with these demands. Continuous generating grinding can contribute to higher transmission performance in several ways. This paper touches on three relevant features that generating grinding contributes to ground gears, and by extension, to the entire transmission. Two of these features, Low Noise Shifting (LNS) and Polish Grinding positively alter the surface structure, and the third, Twist Control Grinding (TCG) adds control over the gear flank geometry and the surface bearing ratios.

6th CTI Symposium and Transmission Expo in China
International transmissions experts meet up for the sixth time in Shanghai
25 – 27 September 2017, Shanghai
Düsseldorf/Shanghai June 2017 – The next International CTI Symposium ’Automotive Transmissions, Hybrid & Electric Drives’ takes place on 25 – 27 September 2017, when automobile experts will gather in China for the sixth time to exchange ideas on transmission technology developments. With 8 lecture series, 60 presentations, 7 keynote speeches and the satellite exhibition ’Transmission Expo’, the event will provide a powerful framework for high-ranking Chinese and international automobile and transmission manufacturers and suppliers. The focus will rest on strategies, new components and development tools for conventional and alternative drives.
The post report of the US Transmission Symposium is out now!
Increasingly, transmissions are becoming part of a connected system that extends beyond the
powertrain and the vehicle. So it’s not surprising the 11th CTI Symposium USA grew again with
now 660 participants, three-quarters of them from North America. Transmission developers’
work is becoming more and more intricate – and with electrification growing, Continue reading
