PULSE VARIATOR OF TRANSPORT VEHICLE Russian patent published in 2013 - IPC F16H47/04 F16H29/08 

FIELD: motor vehicle industry.

SUBSTANCE: pulse variator includes a drive shaft and a driven shaft, mechanism for conversion of rotation of drive shaft to torsion oscillations of pulsating shaft with possibility of controlling the span of those oscillations. Pulsating shaft is connected to the shaft of reversible hydraulic machine of volumetric displacement. Its housing is installed on bearings inside an oil tank. The first inlet-outlet channel of reversible hydraulic machine has the possibility of being interconnected with the tank through the first channel with a check valve and through the second channel parallel to the first channel, which is provided with a safety valve. The second inlet-outlet channel of reversible hydraulic machine is interconnected with the tank through the channel that is open constantly. Housing of reversible hydraulic machine is connected to solar gear of planetary reduction gear, the epicycle of which has an additional gear rim of external engagement, which is kinematically connected to drive shaft of pulse variator. Carrier of planetary reduction gear is connected to drive shaft of pulse variator.

EFFECT: simplifying the device and improving reliability of pulse variator.
