WHEELED VEHICLE SELF-RECOVERY DEVICE Russian patent published in 2000 - IPC

FIELD: transport engineering; antiskidding device for wheeled vehicles. SUBSTANCE: proposed device has base with supports surface, grousers and fixing member. Base has two support members, driving and driven ones, made of flexible material. Side faces of support members form truncated parabola in operating position. Members are interconnected through intermediate plate for turning relative to each other in plane square to longitudinal axis of eyes by means of spring-loaded pins. Grousers are rigidly mounted on free end of external part of driven member support surface and are made in form of gear clamps arranged with displacement relative to each other. Fixing member made in form of three-link clamp is rigidly mounted on driving support member and is installed for possibility of fastening on wheel. Guides with stops are mounted on driven support member, fixing member being connected with guides by pressure rubber braces. EFFECT: enhanced efficiency of device in self- recovering of wheeled vehicles. 4 cl, 2 dwg
