摘要 |
<p>A multiple-ratio transmission (10) with planetary gearing and friction clutch and brake means (56,58,60,68,70) for controlling relative motion of the gearing (22,32) to establish multiple driving ratios between an internal combustion engine (12) and vehicle output shafts (52,54) driving the wheels (72). The clutch (60) and brake means including a forward drive clutch (60) and a reverse drive clutch (56) for establishing torque flow paths through the gearing. The forward drive clutch (60) establishes a torque flow path through the gearing from the engine through a torque output element of the transmission during vehicle startup in forward drive range, and the reverse clutch (56) establishes a corresponding torque flow path during startup in reverse. A mechanical connection between the torque input shaft (16) of the gearing and the crankshaft (14) is characterized by minimal rotating mass, thereby reducing the inertia of rotating mass of the elements of the transmission. <IMAGE></p> |
