Integrated seal for automatic gear

摘要

The seal has a structure (10) in the annular space between a main driven shaft (1), a wheels' half-shaft (2) and the automatic gear's housing (3). A set of radial rubber seals (11-12) is integrated in the structure. They consists of one part (11) with a sealing lip (20) resting against the main driven shaft, and containing an annular spring (21) and a protective ridge (22). A second part (12) has a sealing lip (25) resting against the half-shaft, and a sealing lip (26) resting against a deflector plate (27) acting as a seal against dust and impurities penetrating. The surface sealing element (13) consists of a polymer-based adhesive layer.
