  • Gear change for a vehicle with recovery of the axial play due to differential thermal expansion
    Patent number: 5370014
    Abstract: A gear change for a vehicle comprising an external box made from an aluminum alloy, a main group, a driving shaft of which is adapted to be driven by an engine of the vehicle and a driven shaft of which may be drivingly connected with the driving shaft via a plurality of pairs of gears defining different transmission ratios, and an auxiliary epicyclic group connected in cascade with the main group in which the driven shaft is loaded axially by an elastic member which maintains it in contact with an axial abutment elements to ensure its correct axial positioning upon variations in play due to differential thermal expansion with respect to the box.
