The invention concerns a hydrokinetic coupling apparatus comprising a turbine wheel capable of being interlocked with a driven shaft and housed in an impulse starter wheel with which it can co-operate for hydrokinetic transmission of a torque to said driven shaft, from an input shaft capable of being interlocked with said impulse starter wheel, the turbine wheel and/or the impulse starter wheel being constituted in the form of a wheel (1) including an external doughnut-shaped part (3) fixed on a hub (2) and blades (4) integral with said external doughnut-shaped part (3) and optionally with an internal doughnut-shaped part (8). Said blade wheel (1) is at least partially moulded in one or several parts in synthetic material, in particular a thermoplastic material, a thermosetting material or a synthetic material alloy, said materials being reinforced with resistant fibres.

1. Hydrokinetic coupling apparatus for a lock-up clutch apparatus comprising a turbine wheel coupled to a driven shaft and which is contained within a casing with which it is adapted to cooperate, for hydrokinetically transmitting a torque to the said driven shaft, from a driving shaft which is coupled with an impulse wheel, the impulse wheel being made in the form of a wheel (1) which comprises at least one of an outer toroidal portion (3) and an inner toroidal portion (8), together with blades (4) fixed to the said toroidal portion (3, 8), wherein the blades (4) and the toroidal portion (3, 8) are integrally moulded as a one piece homogeneous body of a synthetic material, which consists of at least one of a thermoplastic material, a thermosetting material, and an alloy of synthetic materials, and wherein said outer toroidal portion is integrally moulded to include an peripheral thickened portion (25) formed with a seating portion for receiving spring members of said lock-up clutch assembly.
