Description

Universal drive device and AGV trolley using same

Technical Field

The utility model belongs to the field of maintenance of wheel sets or bogies, and particularly relates to a universal driving device and an AGV (automatic guided vehicle) using the same.

Background

The wheel pair is the part of the rolling stock contacted with the steel rail and is formed by firmly pressing the left wheel and the right wheel on the same axle. The wheel set has the functions of ensuring the running and steering of the rolling stock on the steel rail, bearing all static and dynamic loads from the rolling stock, transmitting the static and dynamic loads to the steel rail and transmitting the loads generated by unsmooth lines to all parts of the rolling stock.

The bogie is one of the most important parts in the structure of a railway vehicle and mainly comprises two wheel pairs arranged in a front-to-back manner and a fixing frame for connecting the two wheel pairs.

In the maintenance process of the wheel set or the bogie, the wheel set or the bogie needs to be moved at different processing stations, so that different processing of the wheel set or the bogie is realized. When the wheel set or truck is moving, the wheel set or truck needs to be pulled by the AGV trolley because the wheel set or truck itself is not powered.

The drive mechanism is the part of the AGV that provides power for the AGV, and drive mechanism starts, and the AGV just can remove. However, the existing driving mechanism can only drive the AGV to move linearly along a predetermined track, and in some repair workshops performing various processes, the wheel sets need to move in different directions due to the complex construction of the repair workshops. The existing drive mechanism can then no longer meet the requirements of use.
