Abstract:
1. A drive of an agricultural vehicle, with a combustion engine (M), the drive comprising an infinitely variable electrical and mechanical torque split gear (L) including a generator (G) driven by the combustion engine, electric motors to be driven by the generator, a microprocessor to control the number of revolutions, the torque and/or the direction of revolution of the electric motors, planetary gears each having three shafts, wherein a first input of each planetary gear is connectable with the driven shaft of the combustion engine and a second input of each planetary is driven in synchronism with the shaft of an associated electric motor, and a shift gear (F) acting between outputs of the planetary gears and a wheel drive of the vehicle, the shift gear (F) having at least two input shafts ( 2 , 3 ) each connected to at least one transmission step, each of the at least two input shafts ( 2 , 3 ) being in driving connection with a respective planetary gear (P 1 , P 2 ) via a respective clutch (K 1 , K 2 ), the first input of each planetary gear (P 1 , P 2 ) being driveable by a clutch (KV) from the driven shaft ( 1 ) of the combustion engine (M) and the second input of each planetary gear (P 1 , P 2 ) being driveable by a respective electric motor (S 1 , S 2 ), and at least one of the planetary gear (P 1 , P 2 ) being designed to be locked-up.
