Abstract: A transmission module for a hybrid drive vehicle configured to be interposed between an internal combustion engine and a transmission of the vehicle has a tray-like support structure configured to be secured to the engine and defines a housing for a clutch to be interposed between a crankshaft of the internal combustion engine and the module. An actuator controls the clutch. The actuator includes an annular chamber provided in the support structure and opens toward the housing, and an annular piston housed in the annular chamber is axially sliding but angularly fixed. A thrust member is coupled in a rotationally free manner to the annular piston, coaxial thereto and operable to cooperate with a control member of the clutch under the thrust of the piston.

Abstract: A transmission module for a hybrid drive vehicle has a tray-like support structure adapted to be fixed to an internal combustion engine and defining a housing for a decoupling clutch, a first power port for connection to an output member of the decoupling clutch, a second power port for connection to an electric machine, and a module transmission having respective transmission members associated with the power ports, and transmission means connecting the transmission members to each other. The power ports are configured so as to be couplable with respective rotating members of the decoupling clutch and of the electric machine by means of respective axially sliding couplings.

Abstract: A transmission module for a hybrid drive vehicle adapted to be interposed between an internal combustion engine and a vehicle transmission has a tray-like support structure defining a housing for a decoupling clutch and adapted to be fixed to the internal combustion engine. A module drive is carried by the support structure and has a first transmission member adapted to be connected to the decoupling clutch by means of a torsional vibration damper and has a second transmission member adapted to be connected to an electric machine. The torsional vibration damper has an actuator defining a centering with respect to the crankshaft and to a transmission torque converter and has a seat for a support bearing with respect to the support structure.

Abstract: Pulley-torsional damper integrated group comprising a hub adapted to be rigidly connected to a drive member and a pulley connected to the hub. The hub comprises an inner tubular wall and an outer tubular wall. The pulley is angularly coupled to said hub by means of the ring made of elastomeric material. The elastomeric ring has an outer surface towards the pulley and an inner surface towards the hub, and an adhesive is arranged on at least one of the outer or inner surfaces.

Abstract: A tensioner for a belt transmission of a motor vehicle engine has a fixed part configured to be constrained to the engine and provided with a pin defining a rotation axis (A), an arm having a hub portion hinged on the pin and rotatable about the axis (A) and an opposite portion rotatably supporting a pulley configured to cooperate with a transmission belt, a main spring interposed between the fixed part and the arm to exert a thrust on the arm such as to rotate the arm towards the belt, a roller bearing supporting the arm on the pin, and a pair of damping devices exerting on the arm opposite actions so as to minimize the load on the bearing.
