Double-generator parallel power supply system for vehicles

Abstract

The invention provides a double-generator parallel power supply system for vehicles. The double-generator parallel power supply system for vehicles comprises a first power generator and a second power generator, wherein the first power generator is driven by a motor gear train, and the second power generator is provided with a gearbox and driven by a power takeoff. The gearbox is connected with the power takeoff, an output shaft of the power takeoff drives a power shaft of the second power generator through a transmission mechanism, and parallel power balance output of the two power generators is realized through a power line. The transmission mechanism comprises a power takeoff pulley, a second power generator pulley, a toothed belt and a belt tensioning adjustment mechanism, wherein the toothed belt is used for connecting the power takeoff pulley with the second power generator pulley, the belt tensioning adjustment mechanism is used for tensioning the teethed belt, and the transmission ratio of the power takeoff pulley to the second power generator pulley is 1:3. The gearbox is connected with the power takeoff through a clutch, and excitation coils of the two power generators are serially connected with respective multifunctional adjustors and then connected parallelly to realize parallel power balance output. A protective plate is arranged below the power takeoff to effectively protect a power takeoff generation mechanism and connected onto a left frame and a right frame to be placed horizontally. The second power generator is fixed through a support which is mounted on the gearbox.

Description

technical field [0001] The invention relates to a parallel power supply system of dual generators for vehicles, which belongs to the technical field of vehicle fuel generator sets. Background technique [0002] With the development of intelligence and electrification of military equipment, the upper-mounted equipment of combat vehicles has an increasing demand for electric power, and most military vehicles do not have additional power output capabilities. Combat vehicles basically use fuel-fired generator sets to meet the power needs of the bodywork, which occupy the limited equipment space of the vehicle, and at the same time have problems such as high noise, large emissions, difficult cold start, and inconvenient use. [0003] At present, most equipped vehicles use fuel generators to supply power to the vehicle's upper equipment, which has problems such as emissions, noise, cold start difficulties, and inconvenient use. In addition to solving the problem of cold start of ...

Problems solved by technology

Combat vehicles basically use fuel-fired generator sets to meet the power requirements of the bodywork, which occupy the limited equipment space of the vehicle, and have problems such as high noise, large emissions, difficult cold start, and inconvenient use.

[0003] At present, most equipped vehicles use fuel generators to supply power to the vehicle's upper equipment, which has problems such as emissions, noise, cold start difficulties, and inconvenient use.

In addition to solving the problem of cold start of the vehicle itself, the use of fuel generator sets also needs to solve the problem of cold start of the fuel generator set; when the fuel generator set is used, it needs to be moved out of the car, and regular maintenance is also required
