MOTOR VEHICLE ENGINE RPM CONTROLLER WITH CONVERTER OF TRANSMISSION GEAR RATIO DEPENDING UPON OUTPUT SHAFT LOAD Russian patent published in 2008 - IPC F16H37/08 F16H3/74 B60K17/16 

FIELD: engines and pumps.

SUBSTANCE: invention relates to motor industry. The rpm controller represents a device incorporating a planetary differential gear with driving spider (2) and two various-diameter gear wheels (5, 12). Central gear wheel (5) runs opposite to the running spider (2) to transmit engine power to output shaft (6) via the reduction gear that changes the direction of rotation. Central gear wheel (12) runs in the same direction with spider (2) to transmit rotary motion to output shaft (6) via friction clutch (13). Adjusting actuator with a controlled signal, a function of the engine shaft rpm, varies the rotary motion transmission ratio and allows accelerating or decelerating output shaft (6) along with changing the transmission ratio from its maximum to zero.

EFFECT: automatic adjustment of the engine rpm with variation of transmission ratio in transient behavior.
