  • Wheel and brake-drum configuration for vehicles
    Patent number: 4456308
    Abstract: A brake-drum flange is bolted to a wheel disk by an interface surface structure which limits the engagement area and avoids contact around the fastening bolts. In the case of a twin-wheel configuration, the two wheels are placed back-to-back, whereby the contact area has larger diameters than the contact areas between the brake drum and the one-wheel disk.
