hearse, carriage
輬 centers on a wheeled vehicle used for transport, specifically a hearse or a carriage. The two meanings are connected by the idea of a covered, dignified conveyance.
輬 combines 車 (vehicle) with 京, which likely contributes the sound. The character originally referred to a type of light carriage or hearse.
A vehicle (車) with a high, roof-like structure (京) suggests a covered carriage, fitting for a hearse or formal transport.
For リョウ, imagine a hearse carrying a famous person named Ryo: Ryo -> リョウ, and the carriage moves solemnly.
