The pressure sensor 31 is electrically connected to the display through the host, and the laser rangefinder 18 is electrically connected to the display through the host.
When the automobile chassis is tested, the second hydraulic rod 7 is contracted, and the second hydraulic rod 7 pulls the bracket 6 to rotate towards the outer side direction of the bottom plate 1. The chassis of the vehicle is then positioned above the floor 1 and the wheels are supported by the two motorized pulley 3 in the support base 4. The second hydraulic stem 7 is then extended so that the pressure plate 19 presses against the upper end of the chassis of the vehicle. At this time, the pressure received by the pressure sensor 31 is displayed on the display, and the pressure displayed on the display is equal to the pressure of the pressure plate 19 against the chassis of the automobile.
When the pressure of the pressing plate 19 on the chassis of the automobile is adjusted, the first motor 8 rotates first, so that the first gear 9 drives the second gear 10 to rotate. Because the first gear 9 and the second gear 10 are both eccentrically arranged, the first rotating shaft 15 is gradually far away from the output shaft of the first motor 8 in the process that the first gear 9 drives the second gear 10 to rotate. In the process that the first rotating shaft 15 is far away from the output shaft of the first motor 8, the first rotating shaft 15 drives the sliding block 14 and the second sliding frame 17 to slide downwards. At the same time, the first spring 13 is compressed.
During the downward movement of the second carriage 17, the second motor 20, the third gear 21, the fourth gear 22, the push rod 24, and the first slide plate 25 move downward. The second spring 29 is pressed and compressed during the downward movement of the first slider 25. After the second spring 29 is pressed, the pressure of the second spring 29 to the pressure sensor 31 increases, so that the pressure of the pressing plate 19 to the chassis of the automobile increases.
When the pressure value displayed on the display approaches the pressure value set by the pressure plate 19 on the chassis of the automobile, the first motor 8 is turned off. The first motor 8 carries out band-type brake, prevents first gear 9 and second gear 10 rotation.
Then, the second motor 20 drives the third gear 21 to rotate, and because the third gear 21 and the fourth gear 22 are both eccentrically arranged, the second rotating shaft 23 is gradually far away from the output shaft of the second motor 20 and drives the push rod 24 and the first sliding plate 25 to move downwards in the process that the third gear 21 drives the fourth gear 22 to rotate. Because the diameters of the third gear 21 and the fourth gear 22 are equal, the diameters of the first gear 9 and the second gear 10 are equal, and the diameter of the third gear 21 is smaller than the diameter of the second gear 10. Therefore, in the process of driving the fourth gear 22 to rotate by the third gear 21, the push rod 24 and the first sliding plate 25 move downwards, so that the pressure of the pressing plate 19 on the chassis of the automobile can be accurately controlled. When the pressure value displayed on the display is equal to the set pressure value of the pressing plate 19 on the chassis of the automobile, the second motor 20 is turned off, the second motor 20 is used for contracting brake and preventing the first gear 9 and the second gear 10 from rotating. The second motor 20 drives the fourth gear 22 to rotate through the third gear 21, so that fine adjustment of the pressure plate 19 on the chassis of the automobile is realized.
During testing, the motorized pulley 3 is started, the motorized pulley 3 drives the wheels to rotate, and vibration of the chassis of the automobile is monitored in real time through the laser range finder 18. The pressure of the pressure plate 19 on the automobile chassis can be changed, vibration detection of the automobile chassis under different load pressures is realized, and the damping effect of the automobile suspension beam is judged according to the result of the vibration detection of the automobile chassis.
The first hydraulic rod 5 can drive the supporting seat 4 above the first hydraulic rod to move upwards to different heights, so that the height of the automobile cantilever can be independently adjusted. And then the pressure of the pressing plate 19 on the automobile chassis is regulated so that the pressure value of the pressing plate 19 on the automobile chassis is equal to the set pressure value of the pressing plate 19 on the automobile chassis. The vibration detection device can realize full vibration detection on the automobile chassis under different test working conditions, and the vibration absorption effect of the automobile suspension beam on the automobile chassis can be detected under different test working conditions.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
