SELF-CONTAINED CONTINUOUSLY-VARIABLE TRANSMISSION WITH MECHANICAL INTEGRAL TORQUE CONVERTER HAVING AUTOMATIC DRIVE CONTROL

摘要

The invention relates to a transmission for automotive use, comprising a planetary gear system that receives power in the planetary holder and initially transmits said power in a direct manner with low passage ratio by means of the sun gear and subsequently transmits said power in a regulated manner to preserve optimal engine power by means of a planetary gear system mounted inside a cylindrical booster which has an increasing diameter and is coupled to the annular gear and consists of a roller system having a system of rolls and grooves for appropriate adherence to the cone, which receive traction from the conical booster and transmit said traction to a central variable speed gear depending on the required torque that is measured by a sensor mechanism mounted in the sun gear, which can be regulated to maintain an output torque for overdrive or economy. The sun gear is coupled to a shaft (which initially serves as a transmission) having a spiral slot that places the receiving system in the longitudinal position corresponding to the required power in order to contact a given diameter of the cone while synchronizing the change of ratio by subtracting the difference in speeds between the shaft coupled to the central gear and that of the sun gear.
