Problems solved by technology
The power from the transmission or the engine is transmitted to the power take-off through a pair of meshing gears, and the power is transmitted to other equipment through the meshing transmission of another pair of gears and the cooperation between the gear and the shaft. The disadvantage is that the process of shifting gears needs to be stopped first. , cut off the power transmission process, resulting in a waste of time, when there is no load, the noise between the gears is too large, reducing user satisfaction
And it will cause the fire fighting vehicle to stop and change gears. When stepping on the clutch and shifting to neutral gear, connect the gear at one end of the water pump to the output shaft through the coupling sleeve, then shift to gear and release the clutch.
Cannot realize dynamic switching during vehicle driving

The invention relates to a power takeoff device with a synchronizing mechanism. The power takeoff device comprises two sets of gear reducers consisting of three gears, a transmission shaft, an outputshaft, an involute external spline hub and a synchronizer. The three gears are composed of an input gear, an intermediate gear and an output gear which are sequentially connected with one another. Theinput gear and the intermediate gear form the first set of the reducer. The input gear is a driving gear, and the intermediate gear is a driven gear. The input gear is installed on the transmission shaft connected with an engine. The intermediate gear and the output gear form the second set of the reducer. The intermediate gear is a driving gear, and the output gear is a driven gear. The output gear is matched with the output shaft through a needle bearing for idling. The synchronizer is installed on the output shaft, the output gear is connected with a combining sleeve in the synchronizer through the involute external spline hub fixed in the output shaft direction, and thus power can be output through the combining sleeve.
Description
technical field [0001] The invention relates to a power take-off device with a synchronous mechanism, in particular to a power output device for the field of special fire trucks. Background technique [0002] The directional distribution of special vehicle power system is one of the core needs of users, such as vehicle winch transmission, dump truck, explosives on-site mixing vehicle and automobile lifting oil pump, fire truck water pump, and various auxiliary devices in construction machinery, such as Air compressors, fuel pumps, waste collectors, refrigerators, etc., are important components in the field of vehicle power because the power take-off can provide continuous and stable power output. [0003] At present, most of the transmission forms of mainstream power take-offs on the market are gear transmission. The power from the transmission or the engine is transmitted to the power take-off through a pair of meshing gears, and the power is transmitted to other equipment...
