Publication number: 20230030761Abstract: 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.Type: ApplicationFiled: December 24, 2020Publication date: February 2, 2023Applicant: DAYCO EUROPE S.R.L.Inventors: Roberto RONCHETTO, Alessio COURTIAL, Gregorio LUCIANI
