Abstract

The invention provides a method and a system for predicting the service life of a clutch with a displacement sensor booster. The method comprises the following steps: S1, arranging the displacement sensor to detect the position of a piston of the clutch booster through an induction pull rod; S2, recording the initial position, obtained by the displacement sensor, of the clutch booster piston; S3,arranging displacement sensors at intervals for a set mileage; obtaining the current position of a clutch booster piston, when clutch abrasion is judged, calculating the residual abrasion loss, the travel mileage of the unit abrasion loss and the residual endurance mileage, and when the automobile mileage threshold value is reached, outputting the residual abrasion loss, the travel mileage of theunit abrasion loss and the residual endurance mileage. According to the method, the service life of the clutch is predicted, the fault of half-way anchoring of the vehicle caused by insufficient experience or subjective judgment errors of a driver is avoided, and meanwhile, visual clutch use information can be provided for the driver, so that the driver can make a clutch replacement plan.

Description

technical field [0001] The invention belongs to the technical field of commercial vehicle clutch intelligence, and in particular relates to a clutch life prediction method and system with a displacement sensor booster. Background technique [0002] At present, the prediction of the service life of commercial vehicle clutches is mainly based on the driver's driving experience and clutch replacement experience. The driver needs to replace the clutch in time when the clutch is worn to the limit. If the driver is inexperienced or makes a wrong judgment, the vehicle will break down halfway. Secondly, if the driver cannot directly understand the clutch usage, he cannot make a clutch replacement plan in advance. Thirdly, the driver’s driving habits in the initial stage play a key role in the service life of the clutch. For example, in the initial stage, operations such as high engine speed, high-grade start, and large throttle opening will aggravate the slipping of the clutch and ...
