AI Technical Summary
In existing vertical lifting parking systems, the frictional resistance of the top chain drive structure is too high, resulting in low transmission efficiency.
A top slewing bearing toothed chain drive is adopted. By installing a slewing bearing and a shift fork plate on the top of the support frame, the toothed chain drives the shift fork plate on the side of the outer ring of the slewing bearing to rotate, which in turn drives the inner ring of the slewing bearing to rotate, thus reducing friction.
This effectively reduces the frictional resistance of the top transmission, improving the transmission efficiency and stability of the automated parking system.
