Drive for coupling starter-generator-electric-machine, has internal-combustion engine with gear transmission, and change-over device, which is held in condition, in which ratio of number of revolution rotary speed is large

摘要

The drive has an internal-combustion engine with gear transmission ratio depending on the number of revolution rotary speed of the internal-combustion engine. A change-over device is provided for the gear transmission change-over, is held in a condition, in which the ratio of the number of revolution rotary speed is large, by using spring action. The change-over device is switched into a condition, in which the ratio number of revolution rotary speed is smaller, with rising number of revolution rotary speed of the internal-combustion engine.
