Abstract:
An assembly for automatically compensating variations of a spacing between first and second structural members due to manufacturing and/or mounting tolerances, comprising:a bolt having external threads of a first spiral direction, being adapted to extend through said first and second structural members, and comprising a head adapted to be supported against said first structural member, a nut having internal threads of an opposite second spiral direction and adapted to be fixed to said second structural member, and a compensation sleeve having a sleeve-shaped annular member with a through-bore and external threads of said second spiral direction mating to said internal threads of said nut, and a plurality of circumferentially spaced resilient finger sections being defined by longitudinal slots in an end of said sleeve-shaped annular member so as to form a clamping portion-adapted to provide for frictional drag between said compensation sleeve and said bolt, with said compensation sleeve being rotatable relative to said bolt when said is frictional drag has been overcome, such that said bolt when being inserted into said compensation sleeve in an insertion direction and being rotated causes said compensation sleeve to rotate due to said frictional drag therebetween so as to be threaded from said nut in a direction opposite to said insertion direction for compensation of variations in said spacing, and said bolt when said compensation sleeve will have engaged said first structural member is adapted to be rotated relative to said compensation sleeve so as to threadingly engage internal threads of said first spiral direction for clamping said first and second structural members together.
