Continuously variable transmissions (CVT) made a true revolution in the world of automotive industry. However, CVTs weren’t used widely due to lack of synchronization between the driving shaft and other internal parts. This issue led to cutting of gearing teeth, lack of alignments, and complete wedging. This major problem was solved with the help of the stepper motor specially designed for CVTs.

At the 18th International VDI Congress “Drivetrain for Vehicles”, Schaeffler is showcasing its products for IC-engine, hybrid, and electrified powertrains, which will give a new impulse to further development of automobile technologies corresponding to current environmental standards.

The Viscous Coupling (VC) is the transmission component intended for transmission and leveling of torque from the center drive shaft to the front differential, and on to the front wheels. In contrast to the hydraulic coupling and torque converter, the VC uses a different operating principle: torque is transmitted not through dynamic properties of fluid flow, but thanks to viscous properties of the fluid, which fills the internal space of the VC.

Car transmission technologies are developing at a growing rate and should be serviced with the help of more advanced and efficient diagnostic and repair equipment. Therefore, Cottingham Engineering specialists came up with the idea to refurbish old valve body testing machines (first of all, those running on VBDaq and E-ZEE Shift) for company’s customers or simply to buy unused Hydratest machines and find an appropriate application for them.

Commonly, automatic transmissions go into failsafe mode in case of severe system disruptions to protect the powertrain from damage and to inform the car owner about the necessity to visit the automobile repair shop as soon as possible. In this article we will consider the main peculiarities of the automatic transmission failsafe mode, and delve into the possible causes of this issue.

Recently, it has transpired that Liuzhou ZF Machinery Co., Ltd. (LZZF), a joint enterprise between China’s Guangxi Liugong Machinery Co. and ZF Friedrichshafen AG, announced an agreement for the production of the brand-new off-highway gearbox, the model BP230.
