Gears and Transmissions is the fourth volume of the Automotive Technology Series publications and is imended for non-specialists and students or engineers who need to know the rudiments of transmission design and have only a general engineering knowledge.
The function of vehicle transmissions is to convert the output of the engine into useful power at the road wheels, while endeavouring to maintain the most efficient use of fuel over a wide range of road speeds. The first chapter considers the increasing importance of the disposition and layout of the transmission and how it is possible to provide greater con
venitince and space for the passengers or load.
Also discussed are the basic engineering requirements of a transmission.
In further chapters the important aspects of transmission function are expounded, and the different types of clutch mechanisms are contrasted. Gearboxes and gearchanging, and how the choice of gear ratios is made for different types of vehicle are discussed. The attainment of these ratios by the use of gearboxes and variable ratio axles is also outlined.
Acttomatic gearboxes and fullyvariable transmissions are also dealt with, and a chapter follows on overdrives and the improvement in fuel economy effected by their use.
The book concludes with a chapter written by D. Thaw on axle and differential designs for cars and commercial vehicles. Published by: Wife Books Ltd.. 42 Russell Square, London, WC1 .
