Description

Technical Field

[0001] The invention relates to the field of vehicle engineering, in particular to a braking force detection device for vehicle engineering. Background Art

[0002] The braking of a car is the brake, and the braking force is the maximum achievable rolling friction. Because the friction will drop suddenly when rolling changes to sliding, that is, the maximum rolling friction is greater than the sliding friction. At this stage, people need to test the braking condition of the vehicle during the vehicle production process. In vehicle safety, the performance of vehicle braking is a very important link. If the vehicle has braking problems during the process, it will cause serious traffic accidents and bring hidden dangers to people's travel safety.

[0003] The existing braking force detection device for vehicle engineering is used in a braking distance detection or an impact force detection method. The former braking detection will cause great wear to the tires and will be affected by the flatness of the ground, making the detection data inaccurate. The latter braking detection will cause damage to the vehicle body and can basically only detect the same type of vehicle. Its fixed detection device cannot be adjusted according to the size of the vehicle and the spacing between the tires. It has a small scope of application and cannot perform braking force detection on most types of vehicles, which has brought certain adverse effects on people's use process. For this reason, we propose a braking force detection device for vehicle engineering. Summary of the invention

The tachometer 10 can be used to measure the rotation speed of the tire. By using the tachometer 10 in conjunction with the test meter 9, the braking time of the vehicle can be accurately timed so as to detect the braking effect of the vehicle itself. A suction cup 11 is movably connected to one side of the tachometer 10. The sliding grooves 3 are respectively located on both sides of the grooves 12. There are four groups of sliding blocks 4 and suction cups 11. The two groups of suction cups 11 are moved toward each other by moving the screw rod 6. The moving screw rod 6 is movably located at the upper end of the sliding block 4, so that the tire of the vehicle is away from the base 1, and then the suction cup 11 is stably adsorbed on the tire of the vehicle, thereby facilitating the braking force detection of vehicles of different lengths and widths.

[0023] In this embodiment, Figure 3-4 As shown, a groove 12 is provided in the middle of the upper end of the base 1, and a support plate 13 is movably installed in the inner cavity of the groove 12. The two sides of the lower end of the support plate 13 are movably connected with a lifting frame 14, and the lower end of the lifting frame 14 is slidably connected with a slide groove 15. The slide groove 15 is provided on both sides of the upper end of the bottom plate 16, and both sides of the bottom plate 16 are fixedly installed with fixing bolts 17. The two ends of the upper end of the bottom plate 16 are fixedly installed with fixing blocks 18, and a driving motor 19 is fixedly installed on one side of the fixing block 18.

[0025] When the vehicle engineering braking force detection device is used, the support plate 13, the lifting frame 14, the slide groove 15, the bottom plate 16, the fixing bolt 17, the fixing block 18, the driving motor 19, the driving screw rod 20, the movable block 21, the connecting rod 22, and the horizontal rod 23 cooperate with each other to keep the tire of the vehicle away from the base 1, and then the suction cup 11 is stably adsorbed on the tire of the vehicle. When the vehicle passes through the ramp 2 and enters the base 1 above the groove 12, the driving motor 19 drives the driving screw rod 20 to operate, so that the movable block 21 slides and drives the horizontal rod 23 at the upper end of the connecting rod 22 to move, thereby driving the lifting frame 14 to rise and fall, so that the support plate 13 is slowly supported on the bottom of the vehicle and rises, so that the tire is on the support plate 13. The free rotation on the upper part avoids excessive wear of the tire and provides convenience for detection. The tachometer 10 can be used to measure the rotation speed of the tire. Then, by using it in conjunction with the detection meter 9, the vehicle braking time can be accurately timed so as to detect the braking effect of the vehicle itself. The sliding groove 3, sliding block 4, moving motor 5, moving screw 6, moving block 7, support column 8, detection meter 9, and tachometer 10 cooperate with each other to facilitate adjustment according to the position of the wheel. The sliding groove 3 can be used to adjust the distance between the two groups of sliding blocks 4. The moving motor 5 drives the moving screw 6 to run, so that the moving block 7 drives the suction cup 11 to adsorb the wheel, thereby facilitating the braking force detection of vehicles of different lengths and widths.
