Abstract
A concrete mixer truck comprises a vehicle provided with a heat engine and a concrete mixer having a rotating drum and an auxiliary device provided with a unit for generating electric energy that selectively feeds an electric motor connected to the rotating drum. The electric energy generating unit comprises at least an alternator selectively connectable to the heat engine and to a movement unit of the vehicle by means of a gearbox and a power take-off positioned between the clutch of the vehicle and the gearbox. The alternator is configured to convert mechanical energy into alternate electric energy and vice versa. The electric energy generating unit also comprises at least one accumulator and reversible conversion means of electric energy, connected to the accumulator and to the alternator in order to selectively take continuous electric energy from the former and supply alternate electric energy to the latter, to move the drive wheels of said movement unit, or to convert the alternate electric energy produced by the alternator into continuous electric energy to be transferred to the accumulator.
