AUXILIARY DEVICE FOR INCREASING CROSS-COUNTRY CAPACITY OF WHEELED TRACTOR

摘要

FIELD: transport.SUBSTANCE: invention relates to auxiliary devices mounted at vehicle propulsors to increase flotation on slidable roads, in lack of roads, on underlying frozen crust and at low bearing capacity of soil. Proposed device comprises spring-loaded hollow bars fitted one into another. Caterpillar tracks make working members. Said tracks are equipped with grousers and spreaders hinged together by rubber-metal links and interconnected by round hollow bars fitted one into the other and spring-loaded by helical return springs with locking openings, and retainers with flange-type adapter washer fitted on tractor wheel axle and including split joint with bearing.EFFECT: higher flotation and towing-coupling properties.6 dwg
