Non-circular pulley drive technology

Automotive engines are now commonly used by the system and multi-valve variable valve timing technology, which camshaft to the pulse load multiplied, resulting in engine vibration rate increase, affecting vehicle NVH (noise, vibration and smooth) performance, but also on synchronization Tape and other parts damage. In order to maximize low offset this vibration, Leiden (Litens) SmartSprocketTM company invented the non-circular gear technology (CTCcamshaft torque cancellation tech-nology) (Figure 8), which, cam pulley instead of the traditional pure circular, but elliptical or other non-round. In the course of this operation can be offset most of the amplitude, with a 40% reduction in the force and its components, saving and life-enhancing fuel consumption.

Modular and integrated transmission system

The so-called modular transmission is the transmission belt is when (including transmission of the band, round bodies and tension) and the front-end engine auxiliary drive system (in addition to transmission of the drive also includes generators, air conditioning, water pumps, etc.) integrated in the together, users can be assembled to meet the intensive car production now, the complex production process simplified. Gates has developed a system that GEMl0TM yes.

Gates, the company has also developed an integrated auxiliary drive system (Electro-Mechanical Drive, EMD), and adapted to 14 V/42V electrical systems, life has reached 240,000 and 500,000 km of the start number. The system has been in the Peugeot, GM and other new development of 42 V power / starter system applications.
