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.

Transmission module for a hybrid drive vehicle

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.

Transmission module provided with a hydraulic actuator

A pulley unit has a hub configured to be connected to a crankshaft, a pulley coaxial to the hub and supported in a rotationally free manner with respect thereto, a clutch interposed between the hub and the pulley, and an actuator for controlling the clutch, The clutch has an inner disc rotationally coupled to the hub and an engagement portion housed inside the pulley, a mobile member axially movable between an engagement position in which the mobile member rotationally couples the pulley to the engagement portion of the inner disc and a disengagement position in which the pulley is rotationally free with respect to the inner disc, and an elastic element acting on the mobile member to push it towards the engagement position.

Pulley for a motor vehicle engine

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.

An exhaust valve rocker arm assembly operable in a combustion engine mode and an engine braking mode includes: a rocker shaft defining a pressurized oil supply conduit; a rocker arm that receives the rocker shaft and rotates around the rocker shaft, the rocker arm having an oil supply passage therein; a valve bridge that engages a first exhaust valve at a first foot and a second exhaust valve at a second foot; and a capsule assembly disposed on the rocker arm having a capsule body that moves between first and second capsule positions, wherein, in the first capsule position, the capsule body is in a retracted position in the rocker arm offset from the valve bridge, wherein, in the second capsule position, the capsule body extends rigidly for cooperative engagement with the valve bridge.

Self-retracting hydraulic engine brake system

A valve motion measurement assembly is provided for a cylinder valve of an internal combustion engine provided with a valve stem and with a valve head. The valve motion measurement assembly includes a valve position sensor, a supporting bracket provided with at least one sensor seat for the valve position sensor, and a sensor target element configured to be coupled to the valve stem at a distance from the valve head to follow the motion of the cylinder valve. The valve position sensor interacts with the sensor target element for determining the position of the cylinder valve.

Valve motion measurement assembly for an internal combustion engine

A tappet includes a housing with a blind bore and with a shelf groove arranged on the inner wall of the bore; a main body slidably arranged in the bore of the housing, wherein the main body comprises a first shoulder; a secondary body telescopically arranged to the main body and having a second shoulder; a spring device arranged between the first shoulder and the second shoulder; and a locking device extendable from the main body for cooperation with the shelf groove.
