Description
Technical field
The utility model relates to a kind of wet clutch dynamic characteristic measuring field, particularly about a kind of wet clutch friction pair temperature measurement system.
Background technology
Wet clutch is the clutch coupling that surface of friction pair has fluid cooling and lubrication, fluid can take away the heat produced in clutch coupling cohesive process at any time, plurality of advantages such as having little, the long working life of wearing and tearing compared with dry clutch, control is simple, smooth engagement, torque capacity are large, stable performance, noise are low.By means of its good control performance and thermal diffusivity, wet clutch is used widely on numerous endless-track vehicle and engineering machinery.Wet clutch as the critical component in comprehensive actuator, by the combination of friction disc and steel disc be separated the transmission and cut-out that realize power.Due to the sliding wear of friction disc and steel disc in the process that clutch coupling engages, gearshift moment friction disc temperature rise can be caused too high, too high temperature affects road holding and gear shifting characteristic by causing the performance parameters such as the size of friction factor, the moment of friction transmitted, friction pair contact area and wear extent that larger change occurs, even there is the ablation of friction disc, crackle, glue together, stick up the phenomenon such as edge and fatigue breakdown, cause the reduction of the reliability of clutch coupling work, shorten, lost efficacy and even affect the mission life of whole kinematic train and car load serviceable life.A large amount of real vehicle practice and research prove, it is the most important reason causing multi-plate wet clutch friction disc to lose efficacy that the clutch coupling internal temperature field that the heat of friction in wet clutch cohesive process causes changes.Therefore dynamic temperature measurement system and the temp measuring method of researching and developing wet clutch cohesive process friction pair are significant for research wet clutch and trouble saving.
Due to the complicacy of wet clutch under High Rotation Speed state, bring great difficulty to the test of wet type Clutch Dynamic Characteristic.At present, the measurement for wet clutch friction pair temperature is only confined to the laboratory simulation conditions researching stage, subject matter show the simulation of operating mode and real vehicle gap large; The temperature signal low-response gathered, error is large; Temperature measuring equipment is too simple, and signal type is single, only can measure or displays temperature, and the temperature data recorded can not be used for studying the clutch coupling Heating mechanism under clutch coupling sliding wear state.At present, people, on the wet clutch operational factor basis obtained, by setting up the relevant fever phenomenon of finite element model analysis and temperature model, expect the inefficacy of the improvement prevention wet clutch from physical arrangement, material.But, fail so far to set up effectively, the model friction of wet clutch temperature of being generally acknowledged accurately accurately.
