Transmission Testbed

This example shows a testbed with interchangeable transmissions. The transmission models vary from classic four speed transmissions to modern seven, eight, nine, and ten speed configurations. The efficiency and drive ratio can be adjusted by varying the components in each individual transmission configuration. The transmission choices are held in a variant subsystem and are selected by either using the hyperlinks in the model or right-clicking the Transmission subsystem, selecting Variant -> Override using, and the desired variant.


Transmission Variant Subsystem

At this level, the different transmission options are shown as variant subsystems.

The plots below show the input and output speed of the transmission under test. The gear ratios and overall efficiency for the transmission are shown for each gear.
