A protection device for a sealing ring and associated sealing system for a vehicle transmission component includes a plug which can be joined by means of a bayonet coupling together with an annular element configured to fit coaxially within the sealing ring in order to protect it during the insertion of a rotating shaft inside the sealing ring. The plug is provided with a cup portion which can be coupled in a fluid-tight manner inside a sleeve portion of the annular element by end sections of the sleeve and cup portions, the end sections being delimited by facing conical surfaces having different angles and are coupled together by an interference fit.

Protection device for a sealing ring, in particular an oil sealing ring for vehicle transmission components and associated sealing system

An integrated protection component for a sealing ring and associated sealing system for a vehicle transmission component, including a plug that can be inserted inside the sealing ring and an annular element for protecting the sealing ring during insertion of a rotating shaft is provided. The annular element includes a flange-shaped end and a tubular side wall that directly comes into engaging contact with the sealing ring and receives inside it the rotating shaft. The first end being provided with a handle, the plug engaging in a removable manner with the annular element and the tubular side wall being provided with a first weakened zone formed longitudinally alongside a second, radially formed, weakened zone of the first end so as to break following a pulling force exerted manually on the handle.
