1、AE-29 Design Practices Passenger Car Automatic T ransmissions Design Practices Passenger Car Automatic T ransmissions Design Practices Passenger Car Automatic T ransmissions Fourth Edition Fourth Edition Fourth Edition Since the mid Twentieth Century, automatic transmissions have benefited drivers b

2、y automatically changing gear ratios, freeing the driver from having to shift gears manually. The automatic trans- missions primary job is to allow the engine to operate in its speed range while providing a wide range of output (vehicle) speeds automatically. The transmission uses gears to make more

3、 effective use of the engines torque and to keep the engine operating at an appropriate speed. For nearly half a century, Design Practices: Passenger Car Automatic Transmissions has been the “go-to” handbook of design consider- ations for automatic transmission industry engineers of all levels of ex

4、perience. This latest 4th edition represents a major overhaul from the prior edition and is arguably the most significant update in its long history. In summary, this team has put together the most definitive handbook for automatic transmission design practices available today. Virtually all existin

5、g chapters have been updated and improved with the latest state-of-the-art information and many have been significantly expanded with more detail and design consideration updates; most notably for torque converters and start devices, gears/splines/chains, bearings, wet friction, one-way clutch, pump

6、s, seals and gaskets, and controls. In fact, all new chapters have been added, including state-of-the-art information on: lubrication; trans- mission fluids; filtration, and contamination control. Finally, details about the latest transmission technologiesincluding dual clutch and continuously varia

7、ble transmissionshave been added. This edition is made possible in part through sponsorship by The Lubrizol Corporation.
