Lockable differential

摘要

In an economic differential both the axle drive shaft gears driving the vehicle wheels are driven with a fixed transmission ratio by one shaft. The axle drive shaft gears each respectively comprise an outer part, that is an internally toothed ring, and an inner part. Fixed to this is a rotatably mounted worm, which meshes with the internal toothing. The worm is driven either by an oil pump, controllable by a valve, or by an electric motor.
