METHOD OF TRACTION TESTS OF TRANSPORT MACHINES WHEN STARTING AWAY FROM REST UNDER LOAD Russian patent published in 2013 - IPC G01L5/13 G01M17/07 

FIELD: testing equipment.

SUBSTANCE: machine is connected to a traction device with the possibility to measure a traction force applied to a body and directed at the angle to the base. This is provided when a standard hook or a hinge mechanism are used. As a result, a vertical component of this force appears, which provides for sufficient coupling of the machine travel unit with the base. The minimum angle of traction force inclination towards the base is determined on the basis of sufficiency of machine travel unit coupling with the base, which is determined by absence of skidding. The maximum angle of traction force inclination to the base is determined on the condition of starting away from rest for front wheels of the machine off the base. It makes it possible to properly select the necessary angle of traction force inclination to the base both with account of coupling sufficiency and safety of tests.

EFFECT: provision of possibility to perform traction tests of transport vehicles when starting away from rest under load in conditions, when coupling of a machine travel unit with a base is not sufficient.
