Abstract

The invention provides a vehicle hybrid power system which comprises an engine, a drive bridge, a first motor, a second motor, a third motor, a hydraulic pump, a hydraulic motor, a storage battery pack and a first load. The vehicle hybrid power system is characterized by having at least four operating modes. In the first operating mode, the engine directly drives an input shaft of the drive bridge to rotate; in the second operating mode, the engine drives the first motor to generate power, power generated by the first motor drives the second motor to rotate, and the second motor drives the input shaft of the drive bridge to rotate; in the third operating mode, the engine drives the hydraulic pump to pump oil, hydraulic energy generated from the hydraulic pump drives the first load to work; and in the fourth operating mode, hydraulic energy generated from potential energy of the first load drives the hydraulic motor to rotate, the hydraulic motor drives the third motor to generate power, and the power is stored in the storage battery pack. The vehicle hybrid power system has the advantages that fuel economy of the engine is improved, tail gas exhaust is reduced, energy is saved, and emission is reduced. The invention further provides a container stacker provided with the vehicle hybrid power system.

Description

Technical field [0001] The invention relates to the technical field of power systems for construction machinery, and in particular to a vehicle hybrid power system. In addition, the invention also relates to a container stacker. Background technique [0002] In the prior art, a pure electric drive system is generally used in the construction machinery hybrid power system, which first converts the mechanical energy of the engine into electrical energy, and then converts the electrical energy into mechanical energy through the motor. Although the fuel economy of construction machinery is solved, energy will be lost in the process of multiple conversion of energy, resulting in lower efficiency. [0003] When construction machinery is running at low speed, high speed, and working, the power required for each working condition is different. The use of pure electric drive cannot achieve the effect of maximizing engine efficiency and energy saving. At the same time, during the operation...
