ABSTRACT:
The invention relates to a hydrodynamic retarder having two independent operating circuits. Opposite a double rotor on the one hand is a stator fixed to a housing, and the rows of vanes concerned are inclined. The other half of the rotor forms with a rotatable stator and a second operating circuit having rows of blades equally effective in both rotational directions. The stator of this second operating circuit can be coupled via a gear unit and a coupling device to the retarder shaft. The gear unit drives the stator in a direction opposite to the direction of rotation of the rotor and with step-up transmission. When braking from a high travelling speed, only the first operating circuit is effective, the stator of the second operating circuit is released by the retarder shaft and freely rotates as well without any braking action. As the speed drops, the coupling device is actuated and the stator of the second operating circuit is driven in the opposite direction, during which the second operating circuit is temporarily emptied. The advantage of this arrangement is high braking force at high speeds of travel, associated with high braking force in the low speed range right down to approx. zero and in both directions of travel, also the retarder does not need to be attached to the gear shift and does not need to feed power in by a driving engine.
