Synchronous power takeoff

Abstract

There is disclosed a synchronous power take-off means, which can realize to take out power from vehicle engines ( speed variators or transfercases ) for driving a generator, a gear pump, a water pump, a vacuum pump, an air compressor and the like. It consists of toothed gearing and gear shift operating parts. Between the power take-off gear disposed on the countershaft and the countershaft gear is mounted a synchronous gear ring, which is inserted in the countershaft gear.

Description

Technical field: [0001] The invention relates to a power transmission device, in particular to a synchronous power take-off device. Background technique: [0002] At present, the power take-off devices produced in China generally have shortcomings such as large volume, heavy weight, small transmission torque, and poor craftsmanship. The power take-off device invented by Muncie Company in the United States has patent numbers: 4573365 and 4573366. It is driven by gears and shifted gears. The operation is composed of two parts. The gear transmission part mainly includes: the shell formed by one-time casting of aluminum alloy material, the power take-off gear that is constantly meshed with the transmission gear of the vehicle gearbox (or transfer case), the intermediate shaft, and the combination of the internal spline structure Ring gear (joint sleeve), a pair of constant meshing driven gears (intermediate shaft gear and output shaft gear) and output shaft with external splines...

[0002] At present, the power take-off devices produced in China generally have shortcomings such as large volume, heavy weight, small transmission torque, and poor craftsmanship. The power take-off device invented by Muncie Company in the United States has patent numbers: 4573365 and 4573366. It is driven by gears and shifted gears. The operation is composed of two parts. The gear transmission part mainly includes: the shell formed by one-time casting of aluminum alloy material, the power take-off gear that is constantly meshed with the transmission gear of the vehicle gearbox (or transfer case), the intermediate shaft, and the combination of the internal spline structure Ring gear (joint sleeve), a pair of constant meshing driven gears (intermediate shaft gear and output shaft gear) and output shaft with external splines, two pairs of symmetrical mounting holes are processed on the housing, one pair of mounting holes is A power take-off gear, an intermediate shaft gear, an adapter sleeve (ring gear), and an intermediate shaft are installed; the other pair of mounting holes are installed with an output shaft gear and an output shaft; The casing, which cooperates with the casing of the gear transmission part to form a complete casing structure of the power take-off device, including shift trigger parts, shift forks and shift fork baffles and other components

The fork of the shift fork is located on the joint ring gear of the gear transmission part; when the shift trigger part rotates, the spring detent in the shift trigger part moves accordingly; thus the shift fork baffle rotates, and the shift fork baffle drives the shifter The fork also moves accordingly; the shift fork pushes the joint ring gear to move laterally, so that the power take-off gear and the intermediate shaft gear enter the meshing state or disengage. Its advantages are small size, light weight, high reliability, and large transmission torque, but its replacement The gear operation must be carried out when the power take-off gear is stationary, which brings a lot of inconvenience to the use
