Abstract

The invention discloses a detection device of a tire pressure monitoring system. The device comprises a detection support, and the detection support comprises a wheel connecting disc installed in themiddle of the axial surface of the wheel to be detected, a supporting rod arranged in the radial direction of the wheel to be detected, an electrical integrated slip ring and a guide support parallelto the axial direction of the wheel to be detected. The axis of the electrical integrated slip ring coincides with the axis of the wheel connecting disc. A rotor of the electrical integrated slip ringis connected to the middle of the wheel connecting disc, a ring sleeve sleeving a stator of the electrical integrated slip ring is hinged to the lower end of a supporting rod, the upper end of the supporting rod is inserted into a fisheye universal ball at one end of a guide support, and a strong magnetic sucker connected with a vehicle body is arranged at the other end of the guide support. According to the invention, the performance and reliability of the tire pressure device are detected in a real operation environment. By adopting an ingenious structure and a high-quality light material,the error of equipment is reduced to the maximum extent, so an automobile tire pressure monitoring and detecting test is carried out on an actual road.

Description

technical field [0001] The invention relates to the field of automobile road testing, in particular to a detection device of a tire pressure monitoring system. Background technique [0002] The detection device of the tire pressure monitoring system is based on the Ministry of Transport's "JT T 1178.2-2019 Safety Technical Conditions for Commercial Trucks Part 2: Traction Vehicles and Trailers" and "GB26149-2017 Passenger Car Tire Pressure Monitoring System Performance Requirements and Test Methods 》The test bench produced. When the car is in operation, tire failure will lead to major traffic accidents. The tire pressure monitoring system can assist the driver to control the tire condition, detect tire failure in time, and avoid traffic accidents to a certain extent. Therefore, according to the existing standards, it is necessary to detect the tire temperature detection device carried by the automobile tire. Internal alarm. [0003] The common detection device for tire p...
