Abstract

The invention discloses a hydraulic start-stop device, comprising a prime mover system, a first hydraulic system, a second hydraulic system and an electrical control system, the prime mover system includes an engine, and is used to provide energy; the first hydraulic system is used to provide power to the prime mover system The energy is transferred and converted, and the energy is output by external work to complete the expected action or function of the equipment; 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 is used to detect The state parameters of the prime mover system, the first hydraulic system, and the second hydraulic system; if the working device driven by the first hydraulic system and the second hydraulic system does not move, and no operation command is received, the engine is shut down. The hydraulic start-stop device provided by the invention has few additional components and occupies a small space; it can reduce the model selection specification of the engine, reduce the total cost of the working machine, and reduce 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 start-stop device. Background technique [0002] Operating machinery includes engineering machinery, agricultural machinery, mining machinery, sanitation machinery, engineering vehicles, industrial equipment, etc. Among them, the power system of the working machine is divided into two categories: one is to use the energy provided by the environment, such as the use of mains power; the other is to use the prime mover carried by the working machine itself, such as internal combustion engine, electric motor and other prime movers. [0003] For working machines with self-contained internal combustion engines, in the process of design and use, there will generally be energy consumption problems of internal combustion engines, especially energy consumption problems under low power output conditions. [0004] In the prior art, the energy consumption of the int...
