Description

Technical Field

[0001] The utility model relates to the technical field of tricycles, in particular to a brake mechanism for a tricycle. Background Art

[0002] The vehicle hub wire brake braking method has been used in bicycles, two-wheeled motorcycles and small three-wheeled electric vehicles with hub motors for a long time, but this braking method has not been used in cargo tricycles. Later three-wheeled electric vehicles have a small number of pedal-type wire brakes. Later tricycles use a pull-rod brake method, but this pull-rod method can only brake one wheel, so the braking effect is poor. It is more difficult to brake the tricycle after loading, so it cannot meet people's needs. Utility Model Content
