ABSTRACT:
An integrated sealing system for automatic transmission made up of a sole part composed essentially of annular structural metal element (10), suitable for assembling in the annular space between the main shaft (1) and semi-shaft of the wheel set (2) and casing (3) of the automatic transmission; and a set of rubber sealing elements to seal all the interstices in that area of the automotive vehicle mechanism, incorporated in the annular structural element (10) formed by radial sealing element (dynamic sealing) (11)-(12); and surface sealing (static sealing); the radial sealing element (11)-(12) consists on the whole of: a first element (11) composed of a rim (20) which seals against the main shaft (1) with a garter type spring (21) to absorb radial efforts; flanges (22) to protect the spring from being released; in addition, the radial sealing element (11)-(12) has a second element (12) consisting of: a rim (25) which seals against the wheel set semi-shaft (2), and a rim (26) that seals against the deflector (27), protects against mud and dust, and is designed to absorb heavy axial motions; the surface sealing element (static sealing) (13) has a thin layer of polymer base glue.
