Disks and wheels are similar and have nearly identical meaning as spiritual symbols. Both are primarily solar symbols.
A disk can symbolize the sun, physical or spiritual, renewal or rebirth, perfection or divinity. A winged disk represents a power from heaven or the spiritual sun. The Egyptian sun god Ra is often depicted as a winged disk or a disk with rays coming down to Earth that end in hands. The winged disk represented the power of light of the god Ahura Mazda in ancient Iran. In Hebrew, it represents the Sun of Righteousness. Variations of a winged disk has been used by many groups and organizations as a symbol inluding Freemasons, Theosophy, Rosicrucians, and even rock groups and motor cycle gangs. A Rosicrucian reference says in part:
“The Winged Globe is the symbol of the perfected soul making its flight back to the source of its creation …”.
The wheel represents the sun spinning across the sky. Nearly all solar religions considered the wheel a sacred symbol. That is why the Mayans never used wheels on carts. To them, it would be like a Christian using a cross as a screw driver. Thw wheel also symbolizes fate or karma. It also represents the chakras or energy centers that link the material and spiritual body. It also represents the cyclic nature of the world.
In Buddhism, a wheel can symbolize the cosmos, the “Wheel of the Law” which symbolizes completeness, symmetry, and reincarnation. It can represent Buddha himself. The Buddha turned the wheel of dharma. A gold wheel represents spiritual power.
In ancient Hindu writtings, a wheel was often a weapon used by Vishnu, an ultimate weapon that conquers desires and passions. That sounds like a symbol of spiritual enlightenment and the Sun Of Righteousness.
The wheel can also represent the spiritually advanced sage who can enter the unmoving center of the wheel and move the wheel without being moved by it.
