TRANSMISSION SYSTEM AND METHOD OF CHANGES FIRST GEAR RATIO Russian patent published in 2017 - IPC F16H37/04 F16H3/00 

FIELD: transportation.

SUBSTANCE: invention relates to a transmission system of a vehicle. The transmission system comprises an input shaft, which can be connected to the control source, and an output shaft, which is connected to the load. The transmission system also contains the clutch unit, which is connected to the input shaft, and the first and the second outputs. Also, the transmission system comprises a first clutching means, which is disposed between the inlet and first outlet, and a second clutching means, which is disposed between the inlet and the second outlet, and means for switching stage gear, which is disposed between the inlet and the first or second output, and the transmission unit , the first and second sub-transmissions. Wherein, the first output of clutching module is connected to the first input of the transmission module and the second input of clutching module is connected to the second input of the transmission module. The first and second sub-transmissions comprise an input shaft and an output shaft, which are connected to the inputs and outputs of the transmission unit and comprise one gear stage. Transmission stages are arranged between the input and output shafts.

EFFECT: increase in transmission reliability is achieved.
