Document Type and Number:
WIPO Patent Application WO/2017/097299
Kind Code:
A3
Abstract:
The invention relates to a belt pulley decoupler (1) for transmitting drive torque from belts of an auxiliary unit belt drive to the shaft of one of the auxiliary units, comprising: - a belt pulley (2), a hub (4, 4') which is to be secured to the shaft, and a series connection which is arranged in the drive torque flow between the belt pulley and the hub and consists of a decoupler spring (12, 12') and a wrap-around band (11) that extends in the direction of the rotational axis (13) of the belt pulley decoupler and is arranged radially between the belt pulley and the decoupler spring. Both ends (14, 17) of the wrap-around band should open out radially when the drive torque is transmitted, the first end of the wrap-around band (14), which extends in the drive torque flow on the belt pulley side, is braced against the inner surface (15) of a first sleeve (16) that is rotationally fixed in the belt pulley, and the second end of the wrap-around band (17), which extends in the drive torque flow on the decoupler spring side, is braced against the inner surface (18) of a second sleeve (19) which is rotationally mounted in the first sleeve.
