Abstract
A unit comprising a transmission shaft and elements of constant-speed joints connected to such shaft has a moment of inertia I.sub.G about an axis perpendicular to the transmission shaft and passing through the center of gravity of the unit which is defined by the relation I.sub.G =m.multidot.h.multidot.l, in which m is the mass of the unit and h and l are the distances between the articulation centers of the two joints and the center of gravity. This arrangement prevents radial vibrations of a driving shaft in the region of the joint to be connected to a wheel.
Claims8
A motor vehicle transmission comprising:
- a driving shaft;
- a driven shaft;
- a transmission shaft extending between said driving and driven shafts;
- first and second constant-speed joints respectively connecting opposite ends of said transmission shaft to said driving shaft and to said driven shaft;
- and
- means for preventing radial vibration of said driving shaft from being transmitted to said driven shaft, said means comprising a construction of a unit comprising said transmission shaft and elements of said first and second joints connected to said transmission shaft such that said unit has a moment of inertia, about an axis perpendicular to said transmission shaft and passing through the center of gravity of said unit, substantially equal to the product of the mass of said unit, the distance from the center of articulation of said first joint to said center of gravity, and the distance from the center of articulation of said second joint to said center of gravity.
