Real-time detection method for clutch engaging state of loader dead axle type gearbox

Abstract

The invention discloses a real-time detection method for the clutch engaging state of a loader dead axle type gearbox. A microprocessor is adopted in the method, wherein the input end of the microprocessor is connected with a loader gear switch, the output end of the microprocessor is connected with the gearbox with a clutch, a first speed sensor and a second speed sensor are arranged on an input gear and an output gear of the gearbox respectively, and the output ends of the two sensors are connected with the feedback end of the microprocessor. The detection method comprises the steps that an expected gear signal is output to the microprocessor, and the microprocessor judges the clutch at the engaging gear according to the gear signal; then, the speed ratio of the first seat and the second senor is detected in real time, and the clutch is normal if the speed ratio is equal to a preset value in preset time; if the speed ratio exceeds the error range of the preset value, the clutch has the slip fault. The real-time detection method can achieve the purpose that when a certain gear or all gears of the loader are not available due to the abrasion of a certain clutch friction plate of the dead axle type gear body, the fault point can be accurately diagnosed in time.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a method for real-time detection of the clutch engagement state of a fixed-shaft gearbox for a loader. Background technique [0002] With the development of loaders, the fixed-shaft gearbox is gradually being widely used due to its advantages of high transmission efficiency, simple structure, easy guarantee of machining and assembly accuracy, convenient maintenance, and low cost. a kind of like figure 1 The loader fixed-shaft gearbox shown, the gearbox includes an input shaft I with an input gear 2, an output shaft V with an output gear 16, a first intermediate shaft II, a second intermediate shaft III and a third intermediate shaft Shaft IV, wherein the first intermediate shaft II is provided with the first transmission gear 3, the first direction clutch 4 for driving the loader forward, the first gear 5, the first gear clutch 6 and the second transmission gear 7;...
