Embodiment Construction

[0048]In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementations.

[0049]Such asfigure 1 As shown, the first embodiment of the present invention proposes a hydraulic hybrid power device, which includes a prime mover system 100, a first hydraulic system 200, a second hydraulic system 300, and an electrical control system 400. The prime mover system 100 includes a prime mover. To provide energy; the first hydraulic system 200 is connected to the motive power system 100, and is used to transfer and convert the energy provided by the motive power system 100, and perform external work to output energy to complete the expected action or function of the equipment; the second hydraulic system 300 and the motive power The system 100 is connected to absorb and store the energy of the motive power system, and is driven by the stored ene...

Abstract

The invention discloses a hydraulic hybrid power device and a control method thereof. The hydraulic hybrid power device includes a prime mover system, a first hydraulic system, a second hydraulic system and an electrical control system. The prime mover system includes a prime mover for providing energy; The first hydraulic system is used to transmit and convert the energy provided by the prime mover system, and to do work to output energy; the second hydraulic system is used to absorb and store the energy of the prime mover system, and assist the drive of the prime mover system through the stored energy; the electrical control system It is used to detect the state parameters of the prime mover system, the first hydraulic system and the second hydraulic system; and to calculate the state data. When it is identified that the prime mover is overloaded, the second hydraulic system is used to assist the prime mover to work together. The invention has few added components and takes up little space; reduces the model selection specification of the prime mover, reduces the total cost of the operating machinery; and reduces the fuel consumption, emission and noise of the prime mover.

Description

Technical field[0001]The invention relates to the field of power system control, and in particular discloses a hydraulic hybrid power device and a control method thereof.Background technique[0002]Operating machinery includes engineering machinery, agricultural machinery, mining machinery, environmental sanitation machinery, engineering vehicles and industrial equipment. Among them, the power system of work machinery is divided into two categories: one is the use of energy provided by the environment, such as the use of city electricity; the other is the use of prime movers carried by the work machinery, such as internal combustion engines, electric motors and other prime movers.[0003]For work machines that carry internal combustion engines by themselves, in the process of design and use, there will generally be problems with the power selection of the internal combustion engine, that is, how powerful an internal combustion engine should be selected.[0004]For the power selection of i...
