STAND FOR TESTING SINGLE-AXLE PROPULSION DEVICE AT VARIABLE VERTICAL LOAD AND CURVILINEAR MOVEMENT

摘要

FIELD: transport engineering; testing facilities. ^ SUBSTANCE: proposed stand contains carrier connecting slewing gear with frame on which drive of wheeled propulsion device is mounted, and driving axle with wheel to be tested. Stand is provided with additional frame with second wheel and loading device to create and control variable load in value and frequency. Stand is furnished with two hydraulic cylinders to remove vertical load from wheels under testing and is made with possibility of changing angle of setting of wheeled propulsion device in plan by means of screw tie-rods and with possibility of changing radius of turning of wheel propulsion device by means of bushings installed in carrier. ^ EFFECT: improved efficiency and accuracy of testing of wheeled propulsion device. ^ 2 dwg
