Automatic Transmission Shift Control

Performance of a direct-drive transmission with six shifts (six gears) is compared to a torque converter/automatic transmission with three shifts in Fig. 6.9. Note that the torque converter “broadens” the power transfer bands with the three shifts such that the power line is equally as smooth as the power line produced with six shifts. However, …

Mechanical Transmissions

A vehicle with rear-wheel drive has the components shown in Fig. 6.1. For purposes of discussion, we assume that the mechanical transmission has four gear meshes. (Functionally, a mechanical transmission can be thought of as a black box with gears inside. The meshing of these gears gives an output shaft speed lower than the input …
