DEVICE FOR MEASURING TRACTIVE FORCE Russian patent published in 2006 - IPC G01L5/13 G01L1/22 

FIELD: engineering of devices for measuring alternating load, for example, devices for measuring force in form of direct and reverse traction, transferred from engines to vehicles.

SUBSTANCE: proposed device contains assembly for receiving and transferring force from load source, including resiliently deformable and joint-containing part, on parallel surfaces of which resistive-strain indicators are positioned, while a through groove is made in that part, while surfaces of groove on both sides of longitudinal axis of this part are mutually parallel. Aforementioned assembly contains bar, receiving force from load source, and appropriate link for its transfer, serially mutually interconnected by means of connection, to which aforementioned joint is introduced in form of spherical bearing, while aforementioned resiliently deformable part contains cylindrical part, inserted into aforementioned spherical bearing, within limits of longitudinal section of which aforementioned through groove is positioned, while aforementioned resistive-strain indicators are held inside this groove on parallel surfaces of its walls.

EFFECT: rational utilization of working surfaces of part being resiliently deformed; reduction of active distributed load to point load and, appropriately, increased precision of its measurement by resistive-strain sensors; creation of optimal range of operation of resistive-strain indicators during measurement of active forces.
