Description

Technical Field

[0001] The utility model relates to the technical field of environmental sanitation, in particular to a wheel assembly for a sweeper. Background Art

[0002] The sweeper is an integrated garbage sweeper that combines sweeping and vacuuming. It has the advantages of high work efficiency, low cleaning cost, good cleaning effect, high safety performance, and high economic return rate. It has been widely used in cleaning roads in large, medium and small cities. The sweeper is driven by a battery power source and uses a combination of efficient airflow and high-speed rotating brushes to achieve efficient sweeping. The internal structure includes components such as fans, motors, filters, etc., which can filter dust and garbage in the air to achieve the effect of purifying the air.

[0003] Sweepers are usually used outdoors. Due to the complex outdoor environment and uneven ground, they will pass through speed bumps and potholes, as well as roads near construction areas. In addition to dust and fallen leaves, there is also construction site garbage dropped by construction vehicles, which causes the sweeper to bump and puncture tires during driving, which not only affects the driver's concentration on driving, but also damages the vehicle over time. Therefore, for large sweepers, a higher-strength wheel and tire assembly is needed to ensure the strength of the vehicle under various complex road conditions. Utility Model Content
