Audi Q5 Off-Road Experience Nashik
Transmission, countless cars ZF 8HP eight-speed.
The 400,000 Rolls-Royce Phantom and 24,000 Ram 1500 don t seem to have much in common one is the ultimate automotive extravagance; the other embodies the blue-collar, the values of the working class but as the cliché goes, appearances can be deceiving Under the disparate body is a shared ZF 8HP automatic transmission with eight gears, the auto parts supplier ZF German base Group and these are not only you can find the 8HP paired with 25 families of different engines in vehicles sold in the US If you count all brands, model, body style, and configuration of the drive train, number of places where this transmission appears is enormous.
The popularity of the 8HP is not all that surprising that current trends in the data industry Adding more speed transmission helps the effectiveness of additional gears allow wider dissemination of reports and allow the engine to maintain engine rpm low whenever possible, saving fuel what makes the 8HP novel, however, is its incredible versatility.
According to Bryan Johnson ZF, the 8HP is popular because it is a great multitasker We design to be as flexible as possible, Johnson says that we sell as a kit, rather than working to adapt to the unique constraints of a manufacturer which keeps costs low and maximize potential applications kit approach even extends authorization of the transmission of design at Chrysler, the automaker to ensure a steady supply for its own vehicles and releasing ZF production risk shortages.
According to Johnson, the 8HP has fewer parts than previous automatic six-speed 6HP the company and fits in the same package, which means manufacturers have to make minimal changes to adapt the 8HP to existing powertrains and must not worry about major structural problems ZF is working more closely with car manufacturers on the software side, electronic control for the calibration of things of transmission such as strategy displacement and speed of gear changes.
But the options 8HP beyond different programming software internal clutch packs can be used according to specific needs of a torque transmission manufacturer has a range of 221 lb-ft to 738 lb-a massive ft, but most land applications between 330 and 550 lb-ft available add-ons include a take-off power for all-wheel drive, an ignition engine shutdown, or even an electric motor of 47 hp at up torque converter for hybrid vehicles.
So far, the 8HP was an automotive success ZF News awarded its PACE award in 2010 for the 8HP and transmission continues to make its way into new models Our experience in cars equipped with the 8HP is that you barely notice when he is working, which is exactly how an automatic transmission must function any criticism of the 8HP have to do with individual tunings of an automobile manufacturer applies rather than the unit itself.
If there is a concern with 8HP, it is pure pervasiveness The greatest risk when a single manufacturer provides so many companies is widespread production delays or reminders if problems Fortunately, the 8HP has a record without problem of transmission to doubt that the same transmission can serve two or even tens of completely different vehicles, ZF is proof that the argument is as stupid as a Rolls confused with Ram.
