Description

Technical Field

[0001] This utility model relates to the field of trolleys, and more particularly to a trolley that facilitates easy disassembly and assembly of the trailer brake pan. Background Technology

[0002] Trailer brake discs are a key component of the trailer braking system. Located at the wheels, they are circular and work in close contact with the brake pads. Through the friction between them, the kinetic energy of the trailer is converted into heat energy, thereby slowing down or stopping the trailer. Trailer brake discs are usually made of strong materials such as cast iron, steel, or metal alloys. Some also have ventilation designs or radial cracks to enhance heat dissipation.

[0003] The brake pans used on existing trailers are basin-shaped, with multiple bolts typically installed on the side with the smaller area. When placed on existing trolleys, the curved shape makes them prone to wobbling when placed horizontally on top of the trolley. When placed vertically, the larger side needs to be placed on top of the trolley because of the bolts on the smaller side. The bottom-wide and top-narrow shape also makes the brake pans difficult to move.

[0004] Therefore, those skilled in the art have provided a trolley that facilitates easy disassembly and assembly of the trailer brake pan to solve the problems mentioned in the background art. Utility Model Content
