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





248 MPH Without A Gearbox: Direct Drive -- /INSIDE KOENIGSEGG
On this episode, it's a drivetrain nerd's paradise. Christian Von Koenigsegg talks us through the Direct Drive, gas-electric hybrid system that makes traditional gearing obsolete on the 1,500-hp Koenigsegg Regera.





Transmission Oils – High Temperatures
Transmission lubricants are as crucial to the transmission as motor oil is to the engine. The most important function of the oil in a gearbox is the reduction of the friction and wear which harm metal surfaces, leading to premature failure of the moving and rotating metal components. The higher the temperature, the shorter the oil life! Shell lubricants engineers have developed ‘Shell Spirax’, a world-class transmission range of axle, gear and automatic transmission fluids, to enable drivers, fleet owners and owner operators, to select the oil that will deliver Shell’s optimum value, through enhanced wear protection, long oil life, and efficiency.

Audi A7 | THE NEW S-tronic 7 Speed Transmission
Audi has made a great many enhancements to the seven-speed S tronic -- which has superseded the multitronic -- for the A7 Sportback with front-wheel drive. In contrast to the quattro S tronic, the clutches are no longer radially stacked but rather axially positioned one behind the other. They can be separately supplied with oil as needed. Their compact size allows for low moments of inertia at whichever clutch is inactive. Power flows from the output shaft via a spur gear to the pinion shaft first and then to the front-axle differential. The dual-clutch transmission houses a centrifugal governor in its dual-mass flywheel. Its masses, one attached to each side of the flywheel, move so as to offset the engine's torsional vibrations. The centrifugal governor significantly reduces these unwanted vibrations -- particularly between 1,200 and 1,400 rpm. The engine can consequently operate at very low engine speeds. Audi's new seven-speed S tronic has two separate oil supplies. A 4.5-liter circuit of ATF (Automatic Transmission Fluid) services the dual clutch and mechatronics, comprising the control/operation module as well as electronic, electrical and hydraulic components. The wheel set and the differential are lubricated by 3.5 liters of high-viscosity MTF (Manual Transmission Fluid). This division of oil supplies allowed developers to custom-design every component to fulfill its given purpose. ►Gommeblog.it Videos: Video about Cars, Motorbikes, News, Test Auto & Motos, Test Drive, Video Reviews, Motorsport News and Track Lap.
