DEVICE FOR PROXIMATE ANALYSIS OF TRACTION-COUPLING PROPERTIES OF TRACTOR PROPULSIVE DRIVE

摘要

FIELD: test equipment, in particular, equipment for analysis of traction-coupling properties of tractor wheel propulsive drives furnished with a power take-off shaft. SUBSTANCE: the device uses fixed support 23, longitudinal force transducer 5 linked to it and tractor 22 through a movable coupling, pulley 17 furnished with revolution counter 16 with cable 19 fixed and wound on it, the free end of the cable is attached to fixed support 23, gear train reduction gear 7, whose drive shaft is rigidly kinematically linked with drive wheels 24 through power take-off shaft 15, pulley 17 is fixed to output shaft 9, and trailer 1 that carries reduction gear 7. During tractor motion cable 19 reeling out from pulley 17 produces variable draught resistance causing a slip of wheels 24. Draught resistance and slip of the wheels are detected by means of longitudinal force transducer 5 and revolution counter 16. According to the measurement results, the relation between the slip factor and draught force is determined. EFFECT: reduced test time and enhanced accuracy. 6 cl, 4 dwg
