[0002] A rail flat car, also known as an electric flatbed car, an electric flat car and a trolley, is an in-factory electric transport vehicle, which is divided into two types: trackless and tracked. It is driven by a motor reducer, is simple and flexible to operate, can realize rapid handling of goods, and can also cooperate with a dispatching system to realize automated handling. It is widely used in all walks of life. Usually, rail cars can only move vertically and horizontally, and cannot turn, and have high requirements on the space of the site. If the rail car needs to turn on a curved track, two track wheels are required to achieve differential motion. Generally, motors are used to drive the track wheels separately to achieve differential motion. However, this not only increases the cost of the equipment, but also has high energy consumption, and cannot meet the needs of energy conservation and environmental protection. The rail cars for in-factory transportation on the market cannot turn on a curved track, so a differential structure for a curved rail car is proposed to address this problem. Utility Model Content
