Description

Technical Field

[0002] As the number of operating kilometers of electric passenger cars assigned to urban rail transit lines increases, the odometer is an important device for recording the mileage of electric passenger cars, and is important information for the later maintenance of electric passenger cars. Testing and adjusting the train odometer is an urgent issue.

[0003] Checking the odometer and recording the kilometer value are important tasks in daily and special inspections of electric cars. According to the daily and special inspection regulations of subway electric cars, the mileage of the two leading cars of the electric cars must be recorded during daily and special inspections to ensure accurate recording of the vehicle's mileage and the subsequent maintenance plan of the electric cars. However, when recording the mileage, it is found that the mileage value is occasionally wrong.

[0004] The existing solution requires the odometer to be completely disassembled for adjustment. Disassembly and assembly takes a lot of time, greatly delays production efficiency, wastes a lot of manpower, and cannot test the odometer's accuracy. It usually needs to be repaired while the vehicle is stopped. In addition, the odometer is often shaken by the movement of the vehicle during operation. After long-term use, it is easy to affect the working parameters under large vibration forces, which is difficult to judge with the existing odometer testing and adjustment devices.
