Изобретение ОТНОСИТСЯ к транспортному машиностроению и может быть использовано при полигонных испытани х дл до-водки новых конструкций тракторов .The invention relates to transport engineering and can be used in field tests for the addition of new designs of tractors.
Известно загрузочное устройство дл полигонных испытаний тракторов, содержащее приемную тележку с установленным на ней тормозным башмаком, взаимодействующим с поверхностью полигона и создающим т говое сопротивление определенного уровн . Дл создани колебаний т гового сопротивлени на тележке установлен рычаг, по которому с помощью гидроцилийдра перемещаетс контейнер с балластными грузами 1),A boot device for field testing of tractors is known, which contains a receiving carriage with a brake shoe installed on it, interacting with the surface of the landfill and creating traction resistance of a certain level. To create oscillations of traction resistance, a lever is mounted on the trolley, along which a container with ballast weights is moved with the help of a hydrocyle driver 1)
Недостатком известного устройства вл етс низка долговечность, обусловленна алстрым износом тормозного башмака при взаимодействии с поверхностью полигона. Кроме того, в известном устройстве не обеспечиваетс воспроизведение высокочастотных составл ющих т гового сопротив лени из-за больших инерционных нагрузок , возникающих -при перемещении с большой скорО тью контейнера с балластными грузами.A disadvantage of the known device is the low durability due to the alter wear of the brake shoe when interacting with the surface of the landfill. In addition, in the known device, the high-frequency components of the drag resistance are not reproduced due to the large inertial loads that occur when the container with the ballast weights are moved with a high speed.
Известно также устройство дл загрузки при полигонных испытани х трактора, содержащее канал, заполненный в зкой жидкостью, ajHT, погруженный в жидкость и соединенный с остовом и навесным механизмом трактора 2.It is also known a device for loading in field tests of a tractor, comprising a channel filled with a viscous liquid, ajHT, immersed in a liquid and connected to the frame and the hinged mechanism of tractor 2.
В этом устройстве колебани т гового сопротивлени создаютс измене0 нием высоты погруженной части щита с помощью гидроцилиндра, управл емого от гидросистемы трактора.In this device, the oscillating drag is created by varying the height of the submerged part of the shield using a hydraulic cylinder controlled from the tractor's hydraulic system.
Недостатком известного устройства вл етс низка точность в спроизве5 дени эксплуатационных нагрузок,обусловленна невозможностью воспроизведени высокочастотных составл ющих колебаний т гового сопротивлени изза большой массы щита.A disadvantage of the known device is the low accuracy in producing the operating loads, due to the impossibility of reproducing high-frequency components of the traction resistance due to the large mass of the shield.

Цель изобретени - повышение точности воспроизведени эксплуатационных нагрузок.The purpose of the invention is to improve the accuracy of the reproduction of operational loads.
Это достигаетс тем, что устройство снабжено лопастными колесами This is achieved by the fact that the device is equipped with paddle wheels.
