ABSTRACT:
A differential speed limiting device is for limiting the relative rotational speed between a first member and a second member of a differential which are capable of independent rotation about a common axis of rotation. A plurality of friction discs are alternatively secured to the first and second members and capable of being axially compressed to generate frictional contact therebetween tending to reduce the relative rotation between the first and second members. A peristaltic pump is mounted relative to the members so that relative rotation therebetween produces a peristaltic pumping of fluid which can be applied to the input side of a force multiplier to cause an output side of the force multiplier to operate an annular bellows to produce the axial movement required to compress the plurality of friction discs.
