Abstract
A torque converter includes two differentials, the cage of the first differential receiving the input shaft power and the cage of the second differential driving the power-receiving output shaft. Both differentials have their planet wheels coupled by pairs, the first group constituting a gear train providing a ratio M while the second group constitutes a gear train providing a ratio N, the ratio M/N differing from unity. The converter input shaft is rigid with the first planet carrier while the output shaft is rigid with the second planet carrier cage.
Claims6
A mechanical torque converter operating by differential retroaction, said torque converter comprising:
- a power input shaft;
- a power receiving output shaft;
- first and second differentials, the cage of the first differential being coupled to and receiving the power from said power input shaft, and the cage of the second differential being coupled to and driving said power receiving output shaft;
- and
- said first and second differentials each having planet wheels coupled by pairs such that a first group forms a gear train providing a gear ratio M and a second group forms a gear train providing a gear ratio N, wherein the ratio M/N is other than unity.
