Probably every transmission repair specialist was keen on LEGO constructions or at least enjoyed making some minor things with their hands. Here's the game taken to a new level of creativity!

Modern auto industry is full of sophisticated drivetrain technologies which are supposed to make your driving experience even more pleasant and trouble-free. Despite a great abundance of sophisticated technical solutions, it is highly likely that very few people know a transmission solution operating like a manual CVT.

Over recent years engineers developed a lot of gear shifting solutions for different car brands, which may seem a bit unusual for oldtime drivers. In this article we will review the most peculiar gear stick technologies and provide video materials related to these technologies.

Only few people know about transmission concepts which were popular 70-90 years ago. For men of today, these gearboxes may seem very unusual and weird, but even now some gearboxes that date back to those years are quite competitive in comparison with modern transmissions.

Nowadays Extroid CVTs are commonly known as “toroidal” due to the fact that the working surface of driving and driven discs in this transmission has the form of a torus. Extroid CVT is not a V-belt transmission, but a friction drive CVT.

Schaeffler Takes Over Remainder of Compact Dynamics


Schaeffler Takes Over Remainder of Compact Dynamics

In late 2017 Schaeffler Group, a major supplier of automobile and industrial equipment, announced acquisition of the whole share package of Compact Dynamics from SEMIKRON. Schaeffler previously bought the controlling interest (51%) and now the bargain was related to the rest 49 % of shares.


This step is also considered to be a serious investment in future opportunities and a great contribution to diversification of the product range. Compact Dynamics GmbH is specialized in development of electric drives and their control systems. Schaeffler and Compact Dynamics have been collaborating in the field of electric drives for a long time, and as a result designed the e-motor drive used in electric vehicles motor racing.


The takeover deal emphasizes serious intentions of Schaeffler in enhancing its technological expertise in this field. By 2020 Schaeffler plans to invest 500 million euros in the development of serial electric drives and hiring 1,200 new employees. In 2018 Schaeffler will open "E-mobility" division, which will unite all design engineering solutions for hybrid and electric cars.
