Description
technical field [0001] The invention relates to the technical field of hybrid vehicle drive, in particular to a drive system and a drive method for a hybrid hybrid concrete mixer truck. Background technique [0002] Concrete mixer truck is a special truck used to transport concrete for construction. Concrete mixer trucks are equipped with cylindrical mixing drums to carry the mixed concrete. During transportation, the mixing drum is kept rotating to ensure that the concrete carried does not solidify. [0003] The power system of the traditional concrete mixer truck is that the engine provides driving force to the vehicle through the drive train, and provides driving force to the mixing tank through the engine power take-off interface and the upper hydraulic system. The rotating speed of the mixing tank is high when driving, which in turn leads to high energy consumption and poor economy of the vehicle. SUMMARY OF THE INVENTION [0004] The invention aims to solve the te...
