INTERNALLY-SPRUNG WHEEL Russian patent published in 1999 - IPC

FIELD: transport engineering; elastic wheels. SUBSTANCE: wheel has separate rim and inner disk connected by flexible members in form of semi-elliptical plates. Novelty, as compared with prototype, is that flexible members are made with section variable in width and thickness to prevent resonance and provide nonlinear characteristics of wheel. One end of flexible member is hinge secured on inner disk and its middle is rigidly secured on wheel rim. Other end can slide in slot made over perimeter of outer cylindrical surface of inner disk to kill vibrations by friction forces. Inner disk plays also the part of brake drum. EFFECT: enhanced smoothness of riding, simplified design of elastic wheel. 4 dwg
