Description

Technical Field

[0001] The utility model relates to the technical field of vehicle detection, in particular to an electromagnetic separation and combination device for displacement measurement of a sideslip inspection platform. Background Art

[0002] Automobile side slip refers to the interaction force between the wheels and the ground during the driving process of the car due to improper coordination between the toe and the camber angle of the wheels. This force is perpendicular to the driving direction of the car, causing the tires to roll and slide at the same time, which deteriorates the handling stability of the car, increases fuel consumption and accelerates tire wear. If the car is allowed to pass a skateboard that can slide freely in the lateral direction, the skateboard will slide sideways due to the above-mentioned force. By checking the side slip amount of the car, it can be determined whether the two parameters of the toe and camber of the front wheels of the car are properly coordinated. The car side slip test bench is widely used in various occasions such as motor vehicle safety performance testing stations. The main structure of the car side slip test bench includes a bench, a skateboard, a release plate, a linkage reset mechanism, a displacement sensor and other components. The performance of the displacement sensor and the accuracy of the linkage reset mechanism directly affect the accuracy of the test results.

[0003] At present, according to the type of sideslip test bench, there are single-plate sideslip test bench and double-plate linkage sideslip test bench. Single-plate sideslip test bench can only detect the sideslip of a single wheel, but cannot detect the whole vehicle. Double-plate linkage sideslip test bench can detect two wheels at the same time to reflect the sideslip of the whole vehicle.

[0004] The most common problem for all the slide-type side-slip test benches on the market during annual metrological calibration is that the synchronization of the two slides is always out of tolerance. The regulations require that the synchronization should not exceed 0.1 mm, but after one year of use, 60 to 70 percent of them cannot meet the calibration requirements. The main reason is that the performance of the displacement sensor has changed or the mechanical parts have worn out, causing the assembly gap to be too large. It is impossible to judge the performance of the displacement sensor and the accuracy of the mechanical parts during daily work, and the accuracy and authority of daily test results cannot be guaranteed. Therefore, an electromagnetic separation and combination device for displacement measurement of side-slip test benches is invented. Utility Model Content

[0048] The electromagnetic detection assembly includes: an electromagnet 40, an iron plate 41, a proximity switch 42, a timer 43, and a switch 44;

[0050] The fixing assembly includes: a connecting plate 50, a coarse screw 51, a fine screw 52, ​​a coarse nut 53, and a fine nut 54;

[0051] Both ends of the electromagnet 40 are fixedly installed with a connecting plate 50, and both ends of the inner cavity of the stand 10 are fixedly installed with two sets of coarse screws 51, and the coarse screws 51 pass through the connecting plate 50, and the fine screws 52 are fixedly installed on one end of the coarse screws 51, and the thread directions of the coarse screws 51 and the fine screws 52 are set to be opposite, so that the tightening directions of the coarse nut 53 and the fine nut 54 can be opposite, the coarse nut 53 is threadedly connected to the coarse screw 51, one end of the coarse screw 51 is located in the coarse nut 53, and the fine nut 54 is threadedly connected to the fine screw 52.

[0053] The working process is as follows:

[0054] Process 1: When detection is required, the car is slowly driven over the slide plate 11.
