A testbed with interchangable transmissions. The transmission models vary from classic four speed transmissions to modern seven, eight, and nine speed configurations. The efficiency
A four-speed transmission with two planetary gears and five clutches. The test sequence steps through the four forward gear ratios, switches to neutral, and then applies a brake clutch to
A fixed helicopter transmission testbed. The gasoline engine provides power that is sent to the main and tail rotors through planetary gearsets. The main rotor shaft is considered rigid,
This model shows a test harness for a Ravigneaux 4-speed transmission. The subsystem uses the Ravigneaux Gear block and five friction clutches to implement four forward ratios plus
A Simpson transmission with three forward speeds and one reverse speed. Two planetary gear sets are linked with a common sun gear. Two disk friction clutches and two band brakes determine
A simple two-speed transmission. Two clutches control which gear is selected. A brake is connected to the output shaft and can be controlled independently.
