Abstract:
1. A hydraulic coupling for use in a vehicle rive train including a pair of rotary members, said hydraulic coupling comprising: a housing in fluid communication with a source of pressurized fluid; a gear case supported for rotation by said housing and operatively coupled to the rotary members; a coupling mechanism non-rotatably supported within said housing and adjacent said gear case, said coupling mechanism operable to selectively couple the pair of rotary members together; a fluid path extending between said housing and said coupling mechanism, said fluid path including a first aperture formed in said housing and having a first diameter at a longitudinal axis, a second aperture formed in said coupling mechanism, a rigid conduit having a first portion extending through said first aperture in said housing and having a diameter less than said first diameter of said first aperture so as to define an adjustment gap such that said rigid conduit can move out of alignment with said longitudinal axis in response to a misalignment between said first and second apertures, and a second portion that is sealingly received in frictional engagement in said second aperture in said coupling mechanism such that said rigid conduit provides resistance to torque imposed upon said coupling mechanism.
