Abstract
The reactor for a torque converter of the invention comprises a moulded body (32) able to be mounted around a reactor shaft (36) via freewheel (34), being arranged coaxially between an impeller (12) and a turbine (24) along one and the same axis (X—X). The body (32) of the reactor is moulded in thermoplastic and is overmoulded around an outer ring (50) that the freewheel (34) comprises. Advantageously, the body (32) also comprises an axial thrust bearing (60) on the same side as the impeller and an axial thrust bearing (62) on the same side as the turbine, which thrust bearings are moulded with the body. The invention applies to torque converters intended for the automatic transmissions of motor vehicles.
