| 20100099527 | DAMPER PULLEY ASSEMBLY HAVING A SAFETY DEVICE - A damper pulley assembly has a hub; a seismic mass connected to the hub to define a dynamic torsional vibration damper; a pulley connected to the hub; elastic means for connecting the pulley in torque-transmitting mode to the hub; and one-way stop means for arresting the pulley in a first stop position with respect to the hub or the seismic mass in a first direction, when the elastic means reach a predetermined torsional load. | 04-22-2010 |
| 20100145591 | DRIVE FOR AN INTERNAL COMBUSTION ENGINE COMPRISING AN OIL WET TOOTHED BELT AND A TENSIONING SHOE - A drive for an internal combustion engine having a predetermined take-up rate (TU) and comprising a drive pulley, a driven pulley, a shoe and an oil wet toothed belt cooperating in contact with a guiding surface of the shoe, presenting an optimised winding angle (α) of the guiding surface to decrease the power dissipated on the toothed belt. | 06-10-2010 |

| 20100255259 | TOOTHED BELT COMPRISING A RESISTANT LAYER AND RESISTANT LAYER THEREOF - There is described a toothed belt comprising an elastomeric material body, in which a plurality of longitudinal filiform resistant inserts is embedded, and a toothing coated by a coating fabric. A resistant layer that increases the resistance to abrasion and thus the resistance to wear of the toothed belt is adhered over the coating fabric. The resistant layer comprises a vulcanisation agent and more than 75% of an elastomer formed by at least one copolymer modified with an unsaturated carboxylic acid salt and obtained from a dien monomer and a nitrile group-containing monomer. The resistant layer is advantageously separated from the fabric and is calendered on the fabric itself. | 10-07-2010 |
| 20100304909 | RESISTANT LAYER FOR A TOOTHED BELT AND TOOTHED BELT THEREOF - There is described a resistant layer for a toothed belt and the toothed belt thereof comprising an elastomeric material body, in which a plurality of longitudinal filiform resistant inserts is embedded, and a toothing coated by a coating fabric. A resistant layer is adhered over the coating fabric, the resistant layer increasing the resistance to wear of the toothed belt and comprising an elastomer formed by a mixture of one or more copolymers, obtained from a dien monomer and a nitrile group-containing monomer, and an anti-friction material selected from the group consisting of molybdenum sulphide, copper powder, graphite, preferably in an amount up to 150 phr. The resistant layer is advantageously separate from the fabric and is calendered on the fabric itself. | 12-02-2010 |
| 20110045929 | PULLEY TENSIONER FOR A BELT DRIVE FOR USE IN CONTACT WITH OIL - A tensioner for a belt drive comprises a pivot defining an axis, a support hinged to the axis and defining a guiding surface preferably having a circular profile, an elastic element for actuating the support and a crown pulley eccentric with respect to the axis and surrounding the guiding surface. The tensioner further comprises a journal bearing to support the pulley on the guiding surface. | 02-24-2011 |
| 20110176939 | DECOUPLEABLE PULLEY FOR CONTROLLING A WATER PUMP - A pulley assembly comprising a locking assembly connected to an input shaft of a water pump, a pulley mounted in a idle condition with respect to the shaft, an armature which is axially mobile in order to selectively cooperate by friction with the pulley, an electromagnet to displace the armature arranged on the axially opposite side of the pulley with respect to the armature, and an elastic element preloaded to maintain the armature in contact against the pulley when the electromagnet is not energised and having a substantially flat shape in its non-preloaded or non-deformed configuration. | 07-21-2011 |
