Mounting assembly for drive shafts in universal joint yokes

A mounting assembly for a universal joint, comprising of:

• a yoke including first and second wings between which a driving shaft is provided, said wings having respective holes;
• a bolt having a head and a stem, and said bolt being arranged transversely to said wings;
• and
• a sleeve receiving the stem of said bolt so that, in an assembled position, said sleeve exerts a pressure on a surface of said driving shaft preventing its axial movement, wherein the stem of said bolt has at least a first, threaded end portion, a second, non-threaded adjacent portion, and a third portion, a diameter of said second portion being slightly larger than an inner diameter of said sleeve, so that when said bolt is inserted into said sleeve, said sleeve expands resulting in an increase of its outer dimensions against said surface of said driving shaft blocking it axially in position as it is pressed against said yoke, and said third portion of said bolt having a diameter slightly larger than said second portion, and said third portion of said bolt is received in one of said holes with no part of said third portion being covered by said sleeve, thereby seating said bolt with respect to said yoke.
