Forces generated in the parking brake of the pallet locking system

Abstract

Automatic parking systems are parking structures with a computer-controlled automated vehicle loading and unloading process using sophisticated technological equipment. The paper describes a construction design for a pallet locking system, which is used to lock parking pallets with or without a vehicle, at a particular location and floor, that is, in a rack cell. This is one of the basic design concept variants of "Multi-Tower" automatic parking systems. This concept makes it possible to store cars stacked in rack cells. Cars on pallets are guided to the vertical cells of the parking system, stacked above each other on pallets, by an electric freight traction elevator. Pallets are stacked into the horizontal cells, on either or both sides, on a given floor of the parking system by means of a chain transfer device. After the pallet has been guided to a particular position, the pallet must be fixed in this position by the pallet locking system so that when the vehicle needs to be retrieved, the chain transfer device can again latch onto it and move it to the traction lift cage without any problems. The locking system also functions as a brake for the pallet carrying the parked vehicle. The paper also presents the theoretical calculations of the pallet brake, which is a crucial element of the pallet locking system of the conceptual variant of the "MULTI TOWER" automatic parking system.
