Abstract
The utility model relates to a rear-wheel hub structure of a racing vehicle. The rear-wheel hub is in a disc structure with a wheel hub bump. A transmission shaft connecting hole for connecting a transmission shaft and an anti-skidding central hole for preventing the transmission shaft from sliding are arranged in an axial geometric center of the wheel hub bump on the rear-wheel hub. A master pin installation bump which is coaxial with the transmission shaft connecting hole and the anti-skidding central hole for connecting a master pin is arranged in the axial geometric center of the wheel hub. Brake disc installation holes for installing a brake disc are distributed circumferentially in the rear-wheel hub. Rim installation holes which pass through the wheel hub bump and fix a rim are further arranged circumferentially in the rear-wheel hub. The anti-skidding central hole arranged uniquely provided by the utility model is used to connect a fastening bolt to fix the transmission shaft to prevent the transmission shaft from sliding, so that the transmission efficiency is improved. The master pin installation bump is used to externally arrange a master pin bearing. The size of the wheel hub can be reduced greatly to save the space for arrangement of a suspension while the master pin is fastened.
