An elastic-rigid arm stores a spare wheel upright in the frunk, freeing trunk space while keeping the wheel secure and easy to retrieve.
A release mechanism and planetary gears let wheel studs self-release on impact while preserving centering accuracy across bolt patterns.
Partly meshed gear arms and a two-way cylinder enable synchronous wheel centering with high positioning accuracy for automated production lines.
Segmented fins and U-shaped ribs reduce ground pressure, allowing heavy equipment to float over wet soil while preventing debris entrapment between wheels.
