Hydrodynamic retarder for goods vehicle has rotor, stator, hydraulic pump that supplies circuit for controlling retarder with oil; hydraulic pump can be reversibly connected via clutch to rotor shaft

摘要

The hydrodynamic retarder has a rotor (2), a stator (3) and a hydraulic pump (4) that supplies the circuit for controlling the retarder with oil. The hydraulic pump can be reversibly connected via a clutch (5) to the rotor shaft (6). The clutch is an electromagnetic clutch with an annular electromagnet (7), a clutch plate (8) attached to the rotor shaft, a second (10) attached to the pump shaft (9) and an armature plate (11) connected to rotate with the pump side plate.
