Abstract

The invention discloses a vehicle-mounted hydraulic constant-speed power generation system. The vehicle-mounted hydraulic constant-speed power generation system is composed of a hydraulic pump set formed by connecting a variable pump and an external oil supplement pump in series. The hydraulic pump set is connected with a vehicle-mounted engine for driving the hydraulic pump set and is further connected with a power generation unit, and the power generation unit is composed of a constant-speed hydraulic motor and a permanent magnet power generator and is connected with electric equipment through an inverter. The variable pump and the constant-speed hydraulic motor form a closed type hydraulic system. The invention further discloses a power generation method. According to the power generation method, the vehicle-mounted engine drives the hydraulic pump set, the variable pump provides hydraulic oil for the constant-speed hydraulic motor so as to drive the permanent magnet power generator to work, the variable pump and the constant-speed hydraulic motor form the closed system, and the external oil supplement pump provides oil flow and supplement oil and dissipate heat for the closed system. The vehicle-mounted hydraulic constant-speed power generation system has the advantages of being easy to manufacture, reliable in performance, small in size, light in weight, capable of generating power in a driving mode or a parking mode and high in power generation quality.

Description

Technical field [0001] The invention involves a car -board power generation field of a civilian or military vehicle, especially a vehicle hydraulic constant -speed power generation system and its power generation method. Background technique [0002] The vehicle generator needs to send a stable voltage and frequency power supply, and it is necessary to keep the generator constant speed. This is easy to achieve when the vehicle is parking, but the engine speed changes randomly during the driving process. This requires other hydraulic or mechanical control to control it.Methods to ensure the constant speed of the generator.The car generation method generally has three types: mechanical transmission, car diesel engine, and hydraulic transmission.Due to the disadvantages of mechanical speed adjustment, large volume, and difficulty in layout, mechanical transmission methods are generally only suitable for parking power generation; vehicle diesel engine power generation method has brou...
