Description

металлическое кольцо 22, и сменные твердые упругие пластины 23.a metal ring 22, and removable hard elastic plates 23.

Кажда пластина выполнена с противоположных сторон, параллельных продольной оси барабана с полукруглыми выемками, образующими совместно с выемками смежных пластин отверстий дл прохода соединительных пальцев 24. Пальцы имеют головки 25, опирающиес нз наружную поверхности пластин 23, средние части, пропущенные через отверсти пластин 23, металлическое кольцо 22, через упругое кольцо 21 и через обод 20 барабана во втулке 26.Each plate is made on opposite sides parallel to the longitudinal axis of the drum with semicircular recesses, which, together with the recesses of adjacent plates, form holes for the passage of the connecting fingers 24. The fingers have heads 25 resting on the outer surface of the plates 23, the middle parts passed through the holes of the plates 23, metal ring 22, through the elastic ring 21 and through the rim 20 of the drum in the sleeve 26.

Каждый палец имеет резьбовой хвостовик дл гайки 27, прит гивающей упругие пластины к ободу барабана и расположенной с его внутренней стороны, а с головкой 25 взаимодействует гусеница 28 транспортного средства.. ,Each finger has a threaded shank for a nut 27, which attracts the elastic plates to the drum rim and is located on its inner side, and the vehicle track 28 interacts with the head 25 ..,

Из балках 2с внутренних сторон выполнены направл ющие поверхности 29 дл точного заезда транспортного средства на стенд,From the beams 2c of the inner sides, guide surfaces 29 are made for accurately driving the vehicle onto a stand,

Стенд работает следующим образом.The stand works as follows.

Дл осуществлени испытани гусеничное транспортное средство заезжает на наклонные балки 2, ориентиру сь по направл ющим поверхност м 29. При дальнейшем движении транспортное средство устанавливаетс на беговые барабаны.4,5 и б и после упора в ограничительную стойку останавливаетс . Перед проведением испытаний осуществл ют частичную разгрузку беговых барабанов 4,5 и 6 от всего транспортного средства 19. Это необходимо дл повышени надежности устройства дл имитации дорожного полотна стенда. Дл этого от системы управлени силовым цилиндром 12 воздействуют на нижнюю раму 11, котора продольно перемещаетс в направл ющих 9 на катках 10. При этом ее клинь 13 через тело качени 17 воздействуют на клинь 16 верхней рамы 14, перемеща ее вверх по колонкам 18. При своем перемещении рама 14 воздействует на остов транспортного средства 19, поднима его и частично разгружа беговые барабаны 4,5,6 от веса транспортного средства. При этом грунтозацепы гусеницы транспортного средства должны полностью контактировать с головками 25 беговых барабанов 4,5,6. После установки транспортного сред- ства на стенде запускают его двигатель, и, включа трансмиссию, производ т испытани транспортного средства, регулиру нагрузку на гусеницы и трансмиссию с помощью электромагнитных порошковых тормозов. При этом гусеницы транспортного средства взаимодействуют через головки 25 с беговыми барабанами 4,5,6. В процессе испытани износу подвергаютс только сменные твердые упругие пластины 23, которые в процессе эксплуатации легко замен ютс новыми.To carry out the test, the tracked vehicle drives into the inclined beams 2, being guided by the guiding surfaces 29. With further movement, the vehicle is mounted on the running drums 4,5 and b and stops after stopping in the limit post. Before testing, the running drums 4,5 and 6 are partially unloaded from the entire vehicle 19. This is necessary to increase the reliability of the device for simulating the roadbed of the stand. For this, from the control system of the power cylinder 12, they act on the lower frame 11, which moves longitudinally in the guides 9 on the rollers 10. Moreover, its wedge 13 through the rolling body 17 acts on the wedge 16 of the upper frame 14, moving it up the columns 18. When its movement, the frame 14 acts on the skeleton of the vehicle 19, lifting it and partially unloading the running drums 4,5,6 of the weight of the vehicle. At the same time, the lugs of the vehicle caterpillar must be fully in contact with the heads of 25 running drums 4,5,6. After the vehicle is installed on the stand, its engine is started, and, including the transmission, tests are carried out on the vehicle, adjusting the load on the tracks and the transmission using electromagnetic powder brakes. In this case, the vehicle caterpillars interact through the heads 25 with the running drums 4,5,6. In the test process, only replaceable hard elastic plates 23 are subjected to wear, which are easily replaced by new ones during operation.

5Описанна конструкци обеспечивает повышение ее надёжности и уменьшение шумности при работе.5 The described design provides an increase in its reliability and reduction of noise during operation.
