ZF 8HP 8-Speed Automatic Transmission

ZF has developed a new automatic transmission for cars with eight speeds that can achieve more than 6% fuel savings. The priority aim in development, however, was not the maximum number of gears, but minimum consumption. ZF engineers had set the bar high to produce a new benchmark for automatic car transmissions. The second generation of the ZF 6HP 6-speed transmission, that entered production only in 2006, defines standards that are hard to top: reaction times faster than human perception, direct engine linkage by early-stage torque converter lock-up and intelligent, adaptive control software, that almost reads the driver's intentions from his foot. But the new transmission is capable of even more - it saves (even more) fuel. It also guarantees ultimate driving enjoyment, as well as the variability needed to be able to use future technologies. http://www.zf.com/corporate/en/products/innovations/8hp_automatic_transmissions/8hp_automatic_transmission.html

Automatic Transmission, How it works ?
Help us to make future videos for you. Make LE's efforts sustainable. Please support us at Patreon.com ! https://www.patreon.com/LearnEngineering The operation of an automatic transmission is explained here with help of animation. Allison-1000 transmission model, which has 6 speed and reverse is used for this purpose. The video starts with an explanation of planetary gear set. Just by engaging few clutch packs different output speed can be achieved in automatic transmission. A brief introduction of the torque converter is also given here. Here is the 2D version of the video. In my opinion this video is more helpful than the 3D video to understand the technology. https://youtu.be/Ugao6jTyM7k Like us on FB : https://www.facebook.com/LearnEngineering Voice-over artist :https://www.fiverr.com/mikepaine
