Abstract

An auxiliary hydraulic motor comprises a fixed casing having a cam, a cylinder block, an internal fluid distributor, and a through shaft which extends inside the casing along the axis of rotation of the cylinder block. The through shaft is constituted by a length of a vehicle transmission shaft. The motor includes an axially moving coupling member suitable, in a first position, for being engaged with the cylinder block and the shaft via first and second mechanical engagement means, and in a second position, for being disengaged from the cylinder block and/or the shaft.
