Description

Technical Field

[0001] This utility model relates to the field of automobile assembly line equipment, specifically to an automobile tire mounting assist arm. Background Technology

[0002] Car wheels are one of the most important components of a car. They come into direct contact with the road surface and, together with the car's suspension, mitigate the impact of driving, ensuring good ride comfort and smoothness, good adhesion between the wheels and the road surface, improving the car's traction, braking, and passability, and bearing the weight of the car. The important role of tires in automobiles is increasingly recognized. A car wheel consists of two parts: the rim and the tire. The rim is a cylindrical metal component that supports the tire and is mounted on the axle. It is also called a wheel rim, steel rim, wheel, or tire rim. Rims come in many varieties depending on their diameter, width, molding method, and material. Installing car wheels requires mounting the rim with the tire onto the front and rear axles. Existing car wheel installation production lines use lifting tools or hoists to align the wheel with the axle before tightening bolts for installation. However, the existing tooling structure is simple, and manual alignment of the wheel with the tooling is still required, which is labor-intensive and physically demanding for workers.
