Description

technical field [0001] The invention belongs to the field of tractors, and relates to a tractor power output torque detection device, in particular to a torque detection device and a detection method for the inner cavity of a tractor gearbox. The device can improve the shifting quality of the tractor and ensure constant power output of the tractor in the same working mode. Background technique [0002] At present, with the increasing market demand for high-power wheeled tractors, especially in Xinjiang and Northeast China, heavy-duty wheeled tractors have occupied a dominant position in the market, and the development of power shift tractors or continuously variable speed tractors is particularly important. protrude. The prominent features of power shift tractors or continuously variable transmission tractors are high degree of intelligence, comfortable driving, light and easy shifting, and can give full play to the working efficiency of the engine according to the actual w...

Problems solved by technology

[0003] Although power shift tractors or continuously variable transmission tractors have relatively intelligent shift functions and comfortable operation modes, there are two problems in shifting gears and complex operations: first, in power shifting, especially When shifting gears within intervals, during the switching process of two different wet clutches, due to problems such as torque, moment of inertia and speed matching, the clutch switching process is often accompanied by a greater sense of frustration; second, in complex operations, it is difficult to operate through the driver. Ensure engine constant power, constant speed output

[0004] In order to solve the two problems of existing tractors, such as the frustration associated with shifting gears and the difficulty in ensuring constant power output during complex operations, it is necessary to develop a torque detection device for tractors, which is installed inside the tractor gearbox. Through the detection mechanism and sensor analysis system , for torque measurement and feedback, real-time monitoring of changes in tractor torque and speed, effective control of the speed difference in the process of matching gear shifting, accurate calculation of engine power output power and speed, to achieve the monitoring function of tractor output power, and improve power shifting Tractor shift quality while ensuring constant tractor power output
