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.

In recent years, cars equipped with automatic gearboxes have gained much more popularity on automotive markets than their manual analogs, especially in the USA and Japan. According recent studies, the market share of cars with automatic transmissions reached 90 %. Germany also follows this trend – one in two cars registered till the end of summer 2018 had an automatic gearbox. Undoubtedly, major manufacturers of powertrain components and other spare parts pay close attention to this automation shift, and ZF Aftermarket is not an exception. The company has added two dozen torque converters supplied by Sachs for motor car gearboxes to its wide range of OE quality car components.

In addition to its numerous parts for Mercedes cars, ZF is now providing Sachs torque converters (TC) for 6HP gearboxes for cars manufactured by other major automakers (BMW, Audi, Porsche, Skoda, VW etc.). According to ZF Aftermarket (ZF Group division) officials, Sachs TCs are perfect for innovative automatic gearboxes. These products have a space-saving design, thus fitting into even the smallest installation space while still ensuring high operating characteristics.

Sachs TCs are also notable for a high hydro-dynamic power flow density and a high rate of adoptability to requirements of car manufacturers. TCs guarantee ideal operation when moving the car from standstill – no matter whether on hilly road surface or in stop-start traffic – offering great driving experience. If a lock-up clutch is additionally mounted on a TC provided by Sachs, it increases the mentioned advantages even higher. The design of the TC lock-up clutch includes a lock-up itself and torsional balancer which keep the transmission from wear and tear during start-up, transmit power more effectively, decrease power losses and the level of noise, and enhance driving dynamics.



Torque converter lock-up explained


The TC is a key unit in automatic gearboxes. This component is an external unit which transmits torque from the engine to the gearbox and serves as a hydraulic clutch to accelerate with the help of two turbines (driving and driven) rotating in the transmission fluid. TCs convert torque from the engine. Because of high loads torque converters often get out of order.

To prevent early wear of the automatic gearbox and its units, ZF Aftermarket encourages drivers to change the ATF every 100,000 km – ensuring that the Sachs TC and related parts in the automatic gearbox always provide best performance characteristics.


About Sachs

The German company Sachs was founded in 1895. It is one of the largest suppliers of original spare parts for major automakers since 1930. In 2011 ZF Sachs was incorporated to ZF Friedrichshafen AG. Every year, Sachs produces more than 500 million shock absorbers, more than 150 million clutches, and more than 4 million torque converters. More than 50 global automakers prefer the reliability of Sachs products.
