The clutch mainly comprises a pressure plate, a driven plate and a clutch output shaft, wherein the pressure plate and the driven plate are fixed on one side of the output shaft, a clutch pedal is fixed on the other side of the output shaft, a spring resetting device is arranged on the pressure plate, a friction plate is fixed on the outer side surface of the driven plate, and the friction plate and a flywheel are in friction transmission under a normal state to transmit the power of the engine to the gearbox; after the clutch pedal is stepped on, the output shaft of the clutch moves away from the flywheel on the engine, the friction plate is separated from the flywheel, the engine is separated from the gearbox, and a driver manually shifts gears, so that the friction transmission time of the friction plate is long, the abrasion of the friction plate is very quick, in order to adapt to the abrasion of the friction plate, the initial position of a piston of the existing clutch booster can be slowly adjusted away from the direction of the clutch, and the force applied by the booster can be matched with the thickness of the friction plate. But no test device is available to detect a clutch booster,

The purpose of the invention is as follows: through the simulation test device, the initial position movement adjusting condition of the piston 22 of the clutch booster 20 installed on a real vehicle can be simulated, so that whether the quality problem exists in the aspect of adjusting the initial position of the piston 22 of the produced product, namely the clutch booster 20, is checked.
The infinitely variable speed motor 30 provides initial unidirectional circular motion for a simulation test device, a first-stage speed reducer, a second-stage speed reducer and a third-stage speed reducer are assumed to reduce speed (the speed ratio is 1: 100000) (the speed ratio of a first-stage speed reducer 40 is 1: 20, the speed ratio of a second-stage speed reducer 50 is 1:50, the speed ratio of a third-stage speed reducer 60 is 1: 100), and finally the rotating speed is output through the third-stage speed reducer 60, and after a clutch friction plate is assumed to be used for 30 ten thousand times in the driving process, the friction plate on the clutch is seriously worn, and the use limit is reached, namely the standard that the friction plate needs to be replaced is reached. Therefore, when the simulation test device is used for testing, the minimum test standard of each booster is 30 ten thousand times, and certainly, more than 30 ten thousand times of tests are also possible. Setting 30 ten thousand tests, the initial position of the piston 22 is deviated by 30mm, the thread pitches of the threads on the threaded rod 80 and the adjusting seat 90 are both 1.5mm, uninterrupted 30 ten thousand tests are carried out at the frequency of 24 times per minute, and calculation can obtain the result
T300000/((24/60)) ═ 750000(s) ═ 12500(min)
V＝S/T＝30/12500＝0.0024(mm/min)
ω ═ V/(p · l) ═ 0.0024/((1.5 × 1/100000)) ═ 160 (revolutions/min)
T: continuously maintaining the time required for 30 ten thousand times at the frequency of 24 times per minute
f: frequency 24 times/min
V: distance of displacement of the piston 22 to the right from the initial position per minute
S: 30mm stroke
p: the pitch is 1.5mm
l: speed reducer speed ratio 1:100000
ω: motor rpm
The rotation speed of the continuously variable motor 30 can be set to 160 revolutions/min.
Of course, the 30 ten thousand uninterrupted tests with the frequency of 24 times per minute are only an assumption, the frequency may not be so high or higher in the actual driving process, and the tester can adjust the execution frequency according to different driving environments which can be met by different vehicle types, wherein the execution frequency is lower than 24 times/min or higher than 24 times/min, and the change of the frequency also needs to correspondingly adjust the rotating speed of the infinitely variable speed motor 30.
Of course, the specific rotation speed ratio of each of the first, second, and third speed reducers is not limited as long as the total rotation speed ratio is 1:100000, and for example, the first speed reducer 40 (speed ratio 1:25), the second speed reducer 50 (speed ratio 1:50), and the third speed reducer 60 (speed ratio 1:80) may be selected.
After the predetermined number of tests is completed, the threaded rod 80 needs to be manually reset to simulate the next test of the clutch booster 20. Specifically, the limiting plate 400 is detached from the push rod 70, the adjusting seat 90 is detached from the housing 61, the threaded rod 80 and the push rod 70 are manually moved to the left for resetting, the adjusting seat 90 is then mounted on the housing 61, and the limiting plate 400 and the push rod 70 are fixed. When the stopper plate 400 is detached from the push rod 70, the stopper plate 400 functions to prevent the right end of the spring loading unit 100 from falling off after being detached from the left support plate 12.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
