ABSTRACT:
A mechanism arranged in combination with a multiple ratio transmission for eliminating gear rattle in the various gear ratios and neutral position of the transmission. Such mechanism includes a gear network that is preloaded with a spring arrangement which imparts a spring torque to each gear mesh in the transmission. The spring torque provided by the spring arrangement has a magnitude greater than the inertia torque of the gear meshes arranged in the transmission and is capable of overcoming torsional acceleration imparted to those gear meshes.
