Hydrodynamic retarder for motor vehicle, comprises bladed primary wheel and bladed secondary wheel, which together forms working chamber filled with working medium

摘要

The hydrodynamic retarder comprises a bladed primary wheel (1) and a bladed secondary wheel (2), which together forms a working chamber (3) filled with working medium. One of the two wheels is axially displaceable with its bladed subareas (1.1,2.1) corresponding to the other wheel. A delay unit (4) is provided for damping the striking of the wheel against a stop (6) during the axial displacement of the wheel into the braking position or non-braking position.
