Problems solved by technology
[0002] The paddy field environment is a mixed environment of mud and water, and the driving environment is complex. The paddy field power equipment is prone to subsidence and slippage during operation and walking.
The four-wheel drive chassis of most existing paddy field power equipment distributes the power to the front and rear axles through the transfer case. Since the ordinary transfer case is a hard-connected structure, the power distribution ratio of the front and rear axles is 1:1 in four-wheel drive, which is difficult to adapt to. The complex running conditions of paddy fields, and the sophisticated power distribution system in the automobile industry cannot adapt to the harsh muddy water conditions of paddy fields, and the price is expensive

specific Embodiment
[0056] (1) Walking on hard roads
[0057] When walking on hard roads, there is no slippage, adopt the two-wheel drive mode, disconnect the electronically controlled friction clutch 17 of the rear axle drive shaft or disconnect the electronically controlled friction clutch 18 of the front axle drive shaft, the paddy field power equipment chassis only relies on Front or rear wheel drive.
[0058] (2) Paddy field environment walking
[0059] When walking in the paddy field environment, due to the complexity of the environment, the four-wheel drive mode is activated, and the electronically controlled friction clutches of the front and rear axle drive shafts are closed at the same time, and the chassis power distribution control system is activated.
[0060] 1) Example in the state of single wheel slipping (taking the left front wheel 3 slipping as an example):
[0061] When the chassis is running in a paddy field environment and the left front wheel is slipping, the speed of the...

The invention discloses an adaptive power distribution system for paddy field equipment, which includes an engine, a clutch, a speed reducer, a front axle, a rear axle, a transfer case, and a differential, and transmits the power of the engine to the transfer case through the clutch and the speed reducer. The transfer case can distribute the power to the front and rear drive shafts, and the stroke-controllable electronically controlled friction plate clutches are respectively installed on the front and rear drive shafts to control the power of the front and rear drive shafts Transmission, install an electronically controlled brake on the four wheels respectively, its function is to give a certain braking force to the wheel when the wheel is idling and slipping to prevent the slipping caused by the wheel idling, and improve the traction of the chassis in the complex paddy field environment , to ensure the normal running of the chassis.
Description
technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an adaptive power distribution system and method for paddy field equipment. Background technique [0002] The paddy field environment is a mixed environment of mud and water, and the driving environment is complex. The paddy field power equipment is prone to subsidence and slippage during operation and walking. The four-wheel drive chassis of most existing paddy field power equipment distributes the power to the front and rear axles through the transfer case. Since the ordinary transfer case is a hard-connected structure, the power distribution ratio of the front and rear axles is 1:1 in four-wheel drive, which is difficult to adapt to. The complex running conditions of paddy fields, and the sophisticated and complex power distribution system in the automobile industry cannot adapt to the harsh muddy water conditions of paddy fields, and the price is expensive.
