METHOD FOR EVALUATION OF VEHICLE CLUTCH MECHANISM TECHNICAL STATE Russian patent published in 2019 - IPC G01M17/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to vehicle clutch mechanism. Method of evaluation of vehicle clutch mechanism technical condition consists in that testing is carried out in two stages. At the first stage, the crankshaft minimum rpm is set at idle speed, the clutch and direct gear are switched off, and the clutch pedal is released. Maximum forces are recorded on engine supports for the whole test cycle, summed up and average is calculated on supports at least three test cycles. During the next tests, the average maximum value of forces on the engine supports is also determined, the obtained value of forces is compared with the rated value and the "adhesion is correctly" is diagnosed if the obtained value of forces is equal to the rated value, or "the clutch slips" if less. At the second stage of tests at minimum frequency of rotation of the crankshaft the clutch, direct transmission and smoothly release the clutch pedal, fixing forces on the engine supports with the period equal to one revolution of the crankshaft. Diagnosing "disc brake pad surface beating" is diagnosed if there is preliminary force at clutch engagement or "proper engagement" if preliminary force is absent.

EFFECT: higher diagnostic efficiency.
