Abstract
A belt pulley decoupler is provided which is to be arranged on a crankshaft of an internal combustion engine and has a hub provided for coupling to the crankshaft, and a connecting flange of which a distal face is in abutment with the hub in order to transmit torque from the hub to a belt pulley. The connecting flange having a geometry to facilitate a form fit for torque transmission both on the distal face and also on a proximal face which is intended to come into contact with a torsional vibration damper.
Claims17
A belt pulley decoupler for arrangement on a crankshaft of an internal combustion engine comprising:
- a hub configured for coupling to the crankshaft and a connecting flange of which a distal face is in abutment with the hub to transmit torque from the hub to a belt pulley, wherein the connecting flange has a geometry to facilitate a form fit for torque transmission both on the distal face and also on a proximal face which is arranged to contact a torsional vibration damper, wherein the hub has a geometry on two end faces thereof to facilitate a torque-transmitting form fit between the crankshaft and the hub on one hand and between the hub and the connecting flange on the other hand.
A belt pulley decoupler for arrangement on a crankshaft of an internal combustion engine, comprising:
- a hub configured for coupling to the crankshaft, wherein the hub includes axial toothing on first and second end faces, the axial toothing on the first end face configured to facilitate a torque-transmitting form fit between the crankshaft and the hub;
- a connecting flange having a distal face in abutment with the second end face of the hub to transmit torque from the hub to a belt pulley, wherein the connecting flange includes axial toothing on the distal face to facilitate a form fit for torque transmission between the connecting flange and the hub;
- and
- a first torsional vibration damper arranged to contact a proximal face of the connecting flange, wherein the hub, the connecting flange, and the first torsional vibration damper are arranged to be coaxial in this order away from the crankshaft.
A belt pulley decoupler for arrangement on a crankshaft of an internal combustion engine comprising:
- a hub configured for coupling to the crankshaft and a connecting flange of which a distal face is in abutment with the hub to transmit torque from the hub to a belt pulley, wherein the connecting flange has a geometry to facilitate a form fit for torque transmission both on the distal face and also on a proximal face which is arranged to contact a torsional vibration damper, wherein the torsional vibration damper is designed with a geometry that facilitates a form fit on the proximal face of the connecting flange facing away from the hub.
