Clutch aging detection method and system

Abstract

The invention relates to the technical field of detection of automobile clutches, in particular to a clutch aging detection method. A position sensor is installed on a clutch in advance for acquiringthe displacement of a power part in the clutch and further forming a displacement signal. The method further comprises the following steps that a processor reads the flywheel torque, engine rotating speed and displacement signal output by an engine; the processor calculates the current transmission torque of the clutch according to the flywheel torque and the engine rotating speed; and the processor is combined with the displacement signal to calculate the reduction amount of the transmission torque of the clutch at the same position, and then the abrasion aging value of the clutch is calculated according to the reduction amount. According to the technical scheme, the clutch aging detection method and system have the beneficial effects that the system and method for automatically detectingthe aging degree of the clutch are provided so that the aging abrasion degree of the clutch can be judged more accurately under the condition that the clutch is not disassembled, automobile maintenance personnel can replace the seriously aged clutch in time, and the safety performance of an automobile is improved.

Description

Technical field[0001]The present invention relates to the detection technology field of automobile clutches, and in particular to a method and system for detecting aging of clutches.Background technique[0002]In automobiles that use clutches, whether it is a manual transmission, a manual transmission or a dual-clutch transmission, the clutch is required to realize the transmission and disconnection of power between the transmission system and the engine. As the car’s service life increases, the clutch will often continue to wear and age during its life cycle. After the clutch wears and ages, its transmission torque characteristics will also have huge changes, which will affect the handling, power and safety of the vehicle. Adverse effects. However, the degree of aging of the clutch is closely related to the driving habits of the driver. Because the driving conditions and habits of each car driver are different, the degree of wear and aging of different vehicles of the same model is a...

Problems solved by technology

With the increase of the service life of the car, the clutch tends to continue to wear and age during its life cycle. After the clutch wears and ages, its transmission torque characteristics will also undergo a huge change, which will have a great impact on the handling, power and even safety of the vehicle. bad influence

However, the aging degree of the clutch is closely related to the driver's driving habits. Since the driving conditions and habits of each driver are different, the wear and aging degrees of different vehicles of the same model are also very different.

The wear and aging degree of the clutch can only be estimated by the driver's own experience, and the operation mode cannot be effectively optimized according to the wear and aging condition
