After the automobile has a clutch, the gearbox and the engine can be temporarily separated by pressing the clutch pedal, so that the gear of the gearbox can be switched.

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, the 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, the friction plate and the flywheel are in friction transmission under normal state, and the power of the engine is transmitted to the gearbox; when the clutch pedal is stepped on, the clutch output shaft moves away from the flywheel on the engine, the friction plate is separated from the flywheel, and the engine is separated from the gearbox to carry out manual gear shifting by a driver, so that the friction transmission time of the friction plate is relatively long, the abrasion of the friction plate is very rapid, the initial position of the piston of the conventional clutch booster can be slowly adjusted away from the clutch direction in order to adapt to the abrasion of the friction plate, and the applied force of the booster can be matched with the thickness of the friction plate. But there is no test device capable of detecting the clutch booster,

The purpose of the invention is that: the initial position movement adjustment condition of the piston 22 of the clutch booster 20 mounted on the real vehicle can be simulated by the simulation test device, so that whether the produced product, namely the clutch booster 20 has quality problems in adjusting the initial position of the piston 22 can be checked.
The infinitely variable speed motor 30 provides initial unidirectional circular motion for the simulation test device, and presumes that the first, second and third speed reducers decelerate (speed ratio is 1:100000) (speed ratio of the first speed reducer 40 is 1:20, speed ratio of the second speed reducer 50 is 1:50, speed ratio of the third speed reducer 60 is 1:100), and finally, the rotation speed is output through the third speed reducer 60, and presumes that after the friction plate of the clutch is 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 which is required to be replaced is reached. Therefore, when the simulation test device is used for testing, the lowest test standard of each booster is 30 ten thousand times, and more than 30 ten thousand times of tests are also possible. Setting 30 ten thousand tests, wherein the initial position of the piston 22 deviates by 30mm, the pitches of the threads on the threaded rod 80 and the adjusting seat 90 are 1.5mm, and the piston is obtained by calculating 30 ten thousand tests continuously at the frequency of 24 times per minute
T=total number/f=300000/((24/60))=750000(s) =12500 (min)
V＝S/T＝30/12500＝0.0024(mm/min)
Ω=v/(p·l) =0.0024/((1.5x1/100000))=160 (revolutions/min)
T: uninterrupted for 30 ten thousand times at a frequency of 24 times per minute
F: frequency 24 times/min
V: distance to the right of the initial position of the piston 22 per minute
S:30mm stroke
And p: pitch 1.5mm
L: speed reducer speed ratio 1:100000
Omega: motor rpm
The rotation speed of the infinitely variable motor 30 can be set to 160 revolutions/min.
Of course, the frequency of 24 times per minute is only one assumption, the frequency may not be as high or higher in the actual driving process, the experimenter can adjust the execution frequency according to different driving environments which are met by different vehicle types, the frequency is lower than 24 times/min or higher than 24 times/min, and the rotation speed of the infinitely variable speed motor 30 is correspondingly adjusted due to the frequency change.
Of course, the specific rotation speed ratios of the first, second and third speed reducers are not necessarily the same, so long as the total rotation speed ratio is 1:100000, 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.
When the preset number of trials is completed, the threaded rod 80 needs to be manually reset in order to simulate the next 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 moved to the left manually to reset, and then the adjusting seat 90 is mounted on the housing 61 to fix the limiting plate 400 and the push rod 70. When the limiting plate 400 is detached from the push rod 70, the limiting plate 400 plays a role of preventing the right end of the spring-loaded device 100 from falling down after being separated from the left support plate 12.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and 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 and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present invention, which is intended to be covered by the scope of the claims of the present invention.
