Description

Technical Field

[0001] This utility model relates to the technical field of truck spare tire lifters, specifically a truck spare tire lifter. Background Technology

[0002] Based on load capacity, trucks can be classified into light, medium, and heavy-duty trucks. Truck tires, as a crucial component, are often used under complex and harsh conditions, requiring them to support the vehicle body, cushion external impacts, maintain contact with the road surface, and ensure vehicle performance. A spare tire is a replacement tire prepared in case a normally used tire malfunctions during driving, preventing the vehicle from moving. Its purpose is to ensure the vehicle can reach the nearest repair shop. Typically, the rim diameter of a medium-duty truck spare tire is 18-24 inches, and its weight exceeds 50 kg. When a tire failure occurs during truck driving, manually moving the spare tire is extremely time-consuming and labor-intensive, and existing systems have some shortcomings.

[0003] For example, the truck spare tire lifter with announcement number CN219821603U includes a main frame, a reducer, connectors, and transmission components. The reducer is connected to the outside of the main frame, and its input shaft is located on the side away from the main frame. A hexagonal nut compatible with an electric wrench is fixedly installed on the input shaft. The reducer drives the transmission components to rotate through the connectors, thereby raising and lowering the spare tire tray under the chain. Although this device can be used effectively to raise and lower truck spare tires, it is usually only suitable for spare tires of the same size. Furthermore, the existing lifting mechanism uses a chain, which is prone to jamming. Because it is inconvenient to use spare tires of different sizes, we have proposed a truck spare tire lifter to solve the aforementioned problems. Utility Model Content
