Abstract
An apparatus and a method for the testing of synchronizing devices. In contrast to a conventional apparatus, in which only one rotating transmission gear or rather its synchronizing cone cooperates with a nonrotating synchronizing ring, it is now possible to test a complete synchronizing device consisting of two transmission gears, two synchronizing rings and one gear-shift sleeve with a hub. A transmission gear is fixedly connected to a rigid frame, the other transmission gear is connected to the drive through a drive shaft. The hub with the gear-shift sleeve is coupled with a flywheel mass on the driven side. The flywheel mass on the driven side is during a first shifting operation connected to the drive and is accelerated to the driving speed for testing. The flywheel mass now rotating at the driving speed is then again delayed until standstill through the synchronizing device during a second shifting operation.
