Structure
1. Main Workbench: Tires are primarily removed on this platform, serving as a place to place and rotate them.
2. Separation Arm: Located on one side of the tire changer, this arm is primarily used to separate the tire from the rim, ensuring smooth tire removal.
3. Inflator/Deflation Device: This device deflates the tire to facilitate inflation or removal. It also includes a pressure gauge to measure air pressure. Typical tires maintain a pressure of approximately 2.2 atmospheres (equivalent to 0.2 MPa).
4. Foot Pedal: There are three foot pedals located underneath the tire changer, providing clockwise and counterclockwise rotation, a release/tightening mechanism, and a rim/tire separation mechanism.
5. Lubricant: This facilitates tire removal and installation, reduces damage during tire removal, and ensures a smoother tire removal process.
6. Compressed Air Port. 7. Classification
8. There are two main types of tire changers commonly found on the market: small vertical tire changers for passenger car tires, and large horizontal tire changers for large truck tires.
9. The main structure of a typical large tire changer consists of a power unit, hydraulic cylinders, support arms, claws, a trolley, and an operating table. Three hydraulic cylinders operate via a hydraulic system: one for opening and retracting the claws, used to clamp and release the tire; the other for rotating the support arms, used to lift and lower the tire; and the third for moving the head back and forth, used to install and remove the tire.
10. While the entire operation is largely automated, the trolley still requires manual operation, increasing labor intensity. If the trolley could also be operated via a hydraulic system, labor intensity would be greatly reduced, fully realizing automation.
