Изобретение относитс к силоизмерительной технивге и предназначено дл использовани в оборудовании, примен емом при исследовании и испытании сельскохоз йственных машин и тракторов.This invention relates to load measuring technology and is intended for use in equipment used in research and testing of agricultural machines and tractors.

По основному авт. св. N 838454 известно устройство дл динамомётрировани навес ных машин, содержащее подвесную раму со стойками и т гами, соединенную с рамой трактора тензозвеном и навесное устройство , при этом стойки и т ги подвижной рамы св заны между собой дополнительной т гой и с рамой трактора, введенным в устройство компенсирующим тензозвеном, а с подвесной р;амой - через роликовые опоры, установленные в направл ющих пазах, которые выполнены в этой раме 1..According to the main author. St. No. 838454, a device for dynamometer hinged machines is known, comprising a hanging frame with struts and rods connected to the tractor frame by a tensile link and a hinged device, while the legs and the bars of the movable frame are interconnected by an additional link and to the tractor frame inserted into the device is compensated with a strain gauge, and with a suspension p; amoy - through roller bearings installed in guide grooves that are made in this frame 1 ..

Недостатком извеснюго устройства вл етс невозможность измерени боковой нагрузки .The disadvantage of the known device is the impossibility of measuring the lateral load.

Цель изобретени - обеспечение измерени отклон ющего момента и боковой силы.The purpose of the invention is to provide a measurement of deflection moment and lateral force.

Поставленна цель достигаетс тем, что устройство снабжено дополнительными тензоМАШИНThe goal is achieved by the fact that the device is equipped with additional tensomachines

Claims

10 top 3 tons of tractor hitch mechanism. The dynamometer frame 1 is suspended from the tractor frame on the 4 and 5 rods, which are hinged to the tractor frame, and are connected to the dynamometric frame with special supports, 6 and 7, consisting of rolling stock and guide grooves. Tires 4 and 5 are interconnected by a pull of 8, and the latter through a compensating tensile link 9 is connected to the tractor frame. Tig 8 consists of two half-widths connected by means of an adjusting device 10. Dynamometer frame 1 in the horizontal plane is connected by two main tension parts 3, 9, and 12 with the frame of the tractor at the points of attachment of the lower bars of the hitch mechanism, which makes it possible to improve the accuracy of the measurement of the deflection moment and obtain the dynamics of its change. Perpendicular to the longitudinal axis of symmetry of the tractor and the tensile link m 11 and 12, additional teizrem 13 and 14 are hinged to the tractor frame, and the tensile link is attached to the dynamometric frame through the rods 15 and 16 and the supports 17 and 18. Ti 15 and 16 are hinged connected to the bars 19 and 20 by adjusting devices 21 and 22 and compensating the reference links 23 and 24. The device operates as follows. When the machine is moving in the working position, the resistance of the machine is transmitted through the lower 2 and upper 3 tons to the suspension dynamometer frame and then to the main tensioner 11 and 12. The tensioner 9 measures the resistance forces to the rolling frame of the suspension dynamometer in supports 6 and 7. Tg 4 and 5, when moving the suspension dynamometer frame, is held in the vertical position by the strain gauge 9. The lateral force arising during operation is transmitted to the suspension dynamometer frame, then through the supports 17 and 18 to the rods 15 and 16 and additional tensors 13 and 14. Wen the traction resistance is defined as the sum of the core 13 and 14 and 23 and compensating 24 tenzozvenev. Deviation -. The torque is defined as the product of the difference between the readings of the main and compensating tensors of the right and left sides by half the distance between the principal tensors 13 and 14. Introducing additional links into the device allows you to measure the lateral loads of the mounted machines. The invention of the device for dynamometer mounted machines on the author. St. G 838454, characterized in that, in order to provide measurement of deflection moment and lateral force, it is equipped with additional strain gauges, located in a plane perpendicular to the longitudinal axis of the tractor frame along the line passing through the attachment points of the main strain gauges to the frame of the outboard machine.
