Gear change transmission with different gear ratios

摘要

The different gear ratios for gear change wheel drives use several (dis)engageable transmission stages, actuated in a random sequence. The total gear ratios from the transmission input to output differ by a specified factor between adjacent gears. The gear ratios of the individual stages conform to the four specified versions. Pref. the individual gear stages follow the specified schemes for generating the gear ratios within the four versions for engagement, or bridging over with a gear ratio 1:1.
