Technical Field
[0001] The utility model belongs to the technical field of RGV trolleys, and particularly relates to a driving brake mechanism of an RGV trolley. Background Art
[0002] New energy vehicles (NEVs) use unconventional fuels as their power source (or use conventional fuels but employ new onboard power units), integrating advanced technologies in vehicle power control and drive to create vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include hybrid vehicles, pure electric vehicles, fuel cell vehicles, hydrogen engine vehicles, gas vehicles, and alcohol-ether vehicles.
[0003] In order to solve the problem of rapid and precise control of the travel coordinates in existing chassis-type passenger car battery swap stations or single RGV traveling vehicles during travel, the requirements for sudden movement and stopping of the vehicle are very high. Therefore, the power motor braking function is used in the past to make the vehicle move and stop suddenly. Therefore, the installation accuracy and power requirements of the reducer and motor are very high, resulting in high costs and frequent failures. Utility Model Content
