FIELD: transport.
SUBSTANCE: invention relates to automotive industry, particularly, to auxiliaries intended for increasing flotation of bad roads. Proposed auxiliary comprises central guide axle to joint support. Top central shaft supports inner bearing axle and two rigidly fitted drive sprockets, two supports with inner ball bearings, four support wheels paired by inner axle with governor flanges, flanged hub ends with ball bearings, driven sprockets integrated into common structural frame. Bearing frame consists of horizontal reaction links and vertical cantilever spring plates fitted on hub assemblies and supports with inner ball bearings on top central shaft.
EFFECT: higher flotation and towing-coupling properties.
