Infinitely variable auxiliary drive for motor vehicles

摘要

Infinitely variable auxiliary drive for motor vehicles, comprising a transmission component arranged between the motor vehicle engine and an auxiliary unit assembly for the infinitely variable adjustment of the transmission ratio, comprising a power-branching planetary transmission with one input base, and two output bases, the speeds of which reciprocally influence one another according to known laws of planetary transmission, a current generating induction machine being arranged according to the invention on one output base and the auxiliary unit assembly being fixed to prevent its rotation on the other. A further fundamental embodiment resides in the fact that the infinitely variable transmission component is a current-generating induction machine with two rotatable pole bases 4; 5, one of which is rotationally connected to the engine and the other to the unit assembly. The speed variation is produced by varying slip on the induction machines by controlling the power output of the latter, the electrical energy occurring being fed to the vehicle mains system. In addition to the economic advantages obtainable by virtue of the auxiliary unit speed variability with the assurance of adequate drive speeds at low engine speeds, avoidance of high noise emission at conventionally feasible increased speeds and the possibility of reducing the overall dimensions of auxiliary units, the drive concept according to the invention ...
