Testing system and testing method for static friction torque of clutch

Abstract

The invention provides a testing system and a testing method for static friction torque of a clutch. The testing system comprises a driving motor, a gear shifting speed reducer, a torque sensor, a clutch assembly, a clutch control mechanism, a transmission shaft, a fixing device, a frequency converter, an upper computer, a data acquisition system and a hydraulic station. The upper computer is connected with the data acquisition system and the driving frequency converter; the data acquisition system is connected with the torque sensor; the driving frequency converter is connected with the driving motor through a cable; the driving motor is connected with the gear shifting speed reducer; the gear shifting speed reducer is connected with the torque sensor; the torque sensor is connected withthe clutch assembly; the clutch assembly is connected with the clutch control mechanism; the clutch control mechanism is connected with the transmission shaft; the transmission shaft is connected withthe fixing device; and the hydraulic station is connected with the clutch control mechanism through an oil pipe. The testing system can conveniently and accurately measure the static friction torqueof the clutch. A running-in test is finished according to a clutch testing standard. No component which is detached is required, and the static friction torque of the clutch can be conveniently and accurately tested.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to a clutch testing system and testing method, in particular to a testing system and testing method capable of measuring clutch static friction torque. Background technique [0002] As we all know, for a traditional tractor, the clutch is one of the important components of the tractor. The clutch is a key transmission assembly connecting the engine and the transmission. It can reliably transmit all the torque generated by the engine to ensure a smooth start of the tractor, reduce the impact load of the drive train during the tractor start process, limit the transmission overload of the drive system, and make the It effectively disengages power. The driving disc of the clutch is connected to the engine, and the driven disc is connected to the transmission. When the clutch is engaged, the output torque of the engine is transmitted to the transmission and the subsequent transmissio...

Problems solved by technology

Compared with the two, the connection of the first test method is time-consuming and laborious, the driving force is uneven, and there are potential safety hazards; the second test method reduces the accuracy of the measurement data because the driving capacity of the hydraulic motor is affected by the oil temperature, and Easy to pollute the environment

[0005] Therefore, the above two test methods have shortcomings
