Patent ID: 8790205

Claim:
A multi-CVT drive system, comprising: a rotary kinetic power source (P 100 ); an epicyclic gear set (EG 101 ) having a left output shaft ( 1011 ) and a right output shaft ( 1012 ); a first continuously variable transmission (CVT 100 ) and a second continuously variable transmission (CVT 200 ), wherein rotary kinetic power output by the rotary kinetic power source (P 100 ) drives the epicyclic gear set (EG 101 ) and said continuously variable transmissions (CVT 100 ,CVT 200 ) are respectively installed between the left end output shaft ( 1011 ) and the right end output shaft ( 1012 ) of the epicyclic gear set (EG 101 ) and respective individual loads including wheel sets (W 100 ,W 200 ), the respective individual loads being driven by respective ones of the two output shafts ( 1011 , 1012 ), so that the wheel sets (W 100 ,W 200 ) of the individual loads driven by the two output shafts ( 1011 , 1012 ) are enabled to perform variation of the driving speed ratio and the driving torque and drive a combined common load body (L 100 ); and a stabilizer device (SDT 100 ) composed of one of a limited slip differential and a dual shaft connecting device having slip coupling torque and connected to the drive system at the following horizontally and coaxially opposite locations on two sides of the common load body (L 100 ), such that when a differential operation is performed between the two individual loads including wheel sets (W 100 ,W 200 ), the stabilizer device (SDT 100 ) stabilizes operation of the drive system, the slip coupling torque being provided by one of a viscous fluid effect, hydrodynamic damping effect, mechanical friction effect, electromagnetic vortex effect, and power generation reverse torque effect, and the stabilizer device (SDT 100 ) being installed at left and right sides of the common load body (L 100 ).
