摘要

A power plant (1) for electric earth-moving and agricultural vehicles with four-wheel drive which comprises a supporting chassis (2), an electric motor drive (3) for driving wheels of the vehicle; the motor drive comprises a gear-type reduction and distribution unit (5) which is installed in a housing which is rigidly coupled to the chassis (2), at least two electric motors (8,9) whose body is fixed to the housing, a front longitudinal distribution shaft (13) and a rear longitudinal distribution shaft (14) which protrude from the housing, two differentials (15,16) which are fitted at the ends of the distribution shafts (13,14) and from which a front axle (17) and a rear axle (18) respectively protrude for respective pairs of driving wheels, at least one of the axles being provided with steering elements; and an assembly (23) for an oscillating support of the front axle which is fixed, in a downward region, to a front end of the supporting chassis (2).
