hydrodynamic speed bumps and device for electronic control of a hydrodynamic retarders

摘要

The retarder (1) has a retarder housing (4) and a controller (2) containing at least one control device (3) mounted in the retarder housing. The control device contains a number of electrical components mounted on at least one carrier element. The con device has a housing that is liquid or oil tight and is mounted in the oil sump of the retarder. An Independent claim is also included for an arrangement for electronically controlling a hydrodynamic retarder.
