摘要

The paper presents the research results in the field of transformable invalid vehicles with the possibility of changing the overall size according to the width. The estimation of the general situation on this issue in the printed media and on the Russian market of invalid equipment is described in this document. The variants of using various mechanisms for changing the overall size according to the width are considered to be taken into account in the design of the wheelchair and the location of the drive wheels. According to the test results, the most promising model of a wheelchair and the mechanism used for changing the overall size across the width is described. The presented comparative analysis confirms the market demand and relevance of the presented research subject.
