Rail flat car, as the name suggests, is a type of flatbed car that runs on the track and is driven by a power supply motor, greatly improving speed and efficiency. Therefore, it is also known as electric flat car, electric rail flat car, electric flatbed car, and so on. As for the structure of a track flat car, it generally consists of an electrical control system, a walking wheel system, a power supply system, a drive system, and a frame, etc. These are the basic structural requirements of a track flat car. A brief introduction is as follows:
1. Power supply system for track flat cars: Common power supply methods include low-voltage tracks, batteries, sliding contact wires, cable trays, and cable reels.
2. Track flat car drive system: mainly includes braking and deceleration parts, generally using F-series parallel axis helical gear reducers, K-series spiral bevel gear reducers, LD reduction structures in the crane industry, and in special cases, planetary gear reducers can also be used. The choice of deceleration drive mainly depends on the specific situation.
3. Track flat car walking wheel system: generally adopts a single wheel drive operation with two axles and four wheels, including a driving axle and a driven axle. The driving axle is connected to the reducer and runs like the driven axle, including bearing seats, axle sleeves, flat keys, wheels, etc.
4. The electrical control system of the track flat car is related to the power supply mode, and there are two operating systems: wired handle control operation and wireless remote control operation.
5. Track flat car frame system: The body structure is manufactured by welding, consisting of steel sections such as channel steel, I-beams, angle steel, etc.
