Integrated sealing system for automatic transmission

An integrated sealing system for an automatic transmission having a main shaft, a semi-shaft of a wheel set, and a casing, the integrated sealing system comprising:

• an annular structural element to be located between the main and semi-shafts, on one hand, and the casing, on the other hand;
• and
• sealing means for sealing all of interstices of an area in which the annular structural element is located,
• wherein the sealing means comprises:
• dynamic radial rubber sealing means located between the annular structural element and the main shaft and the semi-shaft and comprising a first element including a first sealing rim engaging the main shaft, and a second sealing rim engaging the semi-shaft;
• static sealing means located between an external perimeter of the annular structural element and the casing and comprising a layer of a polymer-based glue applied to the external perimeter of the annular structural element;
• a garter spring for biasing the first rim of the first element of the dynamic radial rubber sealing means into engagement with the main shaft and for absorbing radial movement of the main shaft, the first element having flange means against which the garter spring is supported;
• a deflector member, the first element including a third rim engaging the deflector for preventing mud and dust reaching the shafts and for absorbing axial forces;
• and
• grease means provided between the dynamic radial rubber sealing means and the main shaft.
