The present invention relates to a variable wheel with a cross-beam mechanism, which may adjust the rigidity of wheels without a change in wheel components or material quality of contact surfaces. The variable wheel with a cross-beam mechanism comprises: a double wheel plate which is composed of two plates sharing a central shaft, spaced apart from each other, and arranged to face each other; arc-shaped outer wheel modules which are disposed on the outer circumference of the double wheel plate and have a predetermined radius curvature; and a cross-beam which includes two bars having middle ends that are hinge-coupled to each other, having one ends coupled to the inside of the double wheel plate, and having the other ends movably coupled to the inside of the outer wheel module, so that the radius of the outer wheel module changes according to a crossing angle of the two bars.

    본 발명은 교차 보 메커니즘을 지닌 가변형 바퀴에 관한 것으로, 중심축을 공유하며, 서로 이격되고, 서로 마주보며 배치되는 두 개의 판인 이중 바퀴 판, 상기 이중 바퀴 판의 외주에 배치되고, 소정의 곡률 반경을 갖는 호 형태의 외륜 모듈, 두 개의 바를 포함하며, 상기 두 개의 바는 중단이 서로 힌지 결합되되, 일단이 상기 이중 바퀴 판의 내측에 결합되고, 타단은 상기 외륜 모듈의 내측에서 이동 가능하게 결합되어, 상기 두 개의 바의 교차각에 따라 상기 외륜 모듈의 반경이 변화하게 하는 교차 보를 포함하는 것을 특징으로 한다.
