Problems solved by technology

[0004] A power take-off device provided by this application solves or partially solves the technical problem that the power take-off device in the prior art cannot meet the power generation speed requirement of 8000r / min in a specific occasion, and realizes that the power take-off power generation speed reaches 8000r / min. The power port has a gear switching function, and can prevent damage to the power take-off caused by misoperation and shifting. After the input power is interrupted, it can avoid the technical effect of damage to the power take-off when the load generator has a reverse large impact load.

Embodiment Construction

[0073] A power take-off device provided in the embodiment of the present application solves or partially solves the technical problem that the power take-off device in the prior art cannot meet the requirement of the power generation speed of 8000r / min in a specific occasion, and obtains the power of the engine by setting the input shaft , and through at least one intermediate shaft and at least two pairs of speed-increasing gear pairs, the power of the input shaft is increased and transmitted to the output shaft, and the generator is connected to obtain the power of the output shaft. By setting a shift control mechanism in the power take-off gearbox, the shift control mechanism connects the generator to the input shaft through the output shaft, the intermediate shaft, and the speed-increasing gear pair through the shift operation. The power take-off power generation speed reaches 8000r / min, the power take-off port has a gear switching function, and it can prevent the damage of...

Abstract

The invention relates to a power takeoff device. The power takeoff device comprises a power taking gearbox, an input shaft, an output shaft, at least one intermediate shaft, at least two speed-increasing gear pairs and a gear shifting control mechanism. The power taking gearbox is fixed to a vehicle frame. The input shaft is rotationally arranged in the power taking gearbox and connected with an engine. The output shaft is rotationally arranged in the power taking gearbox and connected with an electric generator. The intermediate shafts are rotationally arranged in the power taking gearbox and arranged between the input shaft and the output shaft in parallel. The input shaft is sleeved with a driving gear of the first speed-increasing gear pair of the at least two speed-increasing gear pairs in a spaced mode, and driven gears are fixed to the intermediate shafts. The gear shifting control mechanism is arranged in the power taking gearbox. According to the power takeoff device, the power taking electricity generation rotating speed can reach 8000 r / min; the power takeoff device has the gear shifting function, so that a power takeoff is prevented from being damaged by maloperation gear shifting, and the phenomenon that the power takeoff is damaged due to reverse large-impact loads of the load electric generator is avoided.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a power take-off device. Background technique [0002] At present, most of the power take-off devices used in the chassis mounting system of special off-road vehicles are low-speed power take-offs or gearboxes. The power take-off input comes from the power take-off port of the engine, transmission or transfer case. The power output speed is also low, generally not higher than 3000r / min. [0003] The power take-off device in the prior art cannot meet the requirement of a power generation speed of 8000r / min in a specific occasion, and the power take-off operation may be easily damaged due to a wrong shift operation. device failure. Contents of the invention [0004] A power take-off device provided by this application solves or partially solves the technical problem that the power take-off device in the prior art cannot meet the power generation speed requirement of 8000r / min ...
