Clutch thermal model test method

Abstract

The invention relates to a clutch thermal model test method, and belongs to the technical field of analysis and test. The clutch thermal model test method includes the steps: making first-phase preparations and testing; starting a temperature acquisition module and a computer to realize real-time monitoring of the temperature of a temperature sensor; enabling a clutch pressure plate to engage with a driven plate to a preset torsion position of a torque and starting to enable the clutch to achieve the slipping depth required to test, and then realizing instant separation when keep slipping until achieving the preset time; and utilizing the temperature acquisition module and the computer to read and store the effective temperature change curve, and comparing and analyzing the effective temperature change curve and a thermal model temperature change curve analyzed by software, so as to realize real effectiveness of the thermal model temperature change curve. The clutch thermal model test method has the advantages that the related equipment and devices used by the clutch thermal model test method are common in the market; the clutch thermal model test method is easy to operate and accurate in data. The clutch thermal model test method is used for acquisition and analysis of the temperature change rule curves generated at different combination depth and different slipping time of the clutch.

Description

technical field [0001] The invention belongs to the technical field of analysis and testing, and in particular relates to a testing method for temperature changes produced in a clutch slipping process, and is especially suitable for dry-type diaphragm spring clutches. Background technique [0002] The clutch is located between the engine and the transmission. It is a part of the vehicle transmission system that is directly connected to the engine. The dry dual clutch transmission is currently accepted and recognized by users due to its fast shift response and high transmission efficiency. However, due to the sliding friction strategy and the software-controlled clutch action of the dry-type dual-clutch automatic transmission, it is more likely to cause the clutch to overheat, resulting in decreased clutch performance, reduced wear life, friction plate ablation, deformation and cracking, pressure plate ablation, deformation and Cracking, etc., will eventually cause the vehicl...

Problems solved by technology

However, due to the sliding friction strategy and the software-controlled clutch action of the dry-type dual-clutch automatic transmission, it is more likely to cause the clutch to overheat, resulting in decreased clutch performance, reduced wear life, friction plate ablation, deformation and cracking, pressure plate ablation, deformation and Cracking, etc., will eventually cause the vehicle to lose its driving function. Moreover, the current clutch design mainly uses analysis software such as ANSYS for thermal model analysis, and no actual test is performed to verify the accuracy of the data.
