Изобретение оТЕЮситс к испытательному оборудованию, в частности к стендам дл испытани пружинных упругих элементов.The invention deals with test equipment, in particular with test benches for testing spring elastic elements.

Известно устройство дл испытани спиральных пружин, содержащее пару маховиков , ПР1ЮОДИМЫХ в движение отэлектродвигател и эксцентрично закрепленных осью с крестовиной, котора соедин етс с концами испытуемых ггружии 1A device for testing coil springs is known, which contains a pair of flywheels made in motion from an electric motor and eccentrically fixed by an axle with a crosspiece, which is connected to the ends of test subjects 1

Однако это устройство не позвол ет получить высокую частоту нагружени пружи tuHowever, this device does not allow to obtain a high frequency of loading of the spring tu

Известен таюке стенд дл испытани пружинных упругих элементов, содержащий раму, на которой установлены меха1шэмы статического нагружени упругих элементов , центральный узел с возбудителем и приводной двигатель-) pj .A stand for testing spring elastic elements, comprising a frame on which the mechanisms of static loading of elastic elements are installed, a central assembly with a pathogen and a drive motor, pj, is well known.

Недостатком этого стенда вл етс то, что услови нагружени упругих элементов на этом стенде далеки от реальных .The disadvantage of this stand is that the loading conditions of elastic elements on this stand are far from real.

Цель изобретени - приближ-оние условий пагружени упругих элементов к реальным путем передачи на них поперечных усилий.The purpose of the invention is the approximation of the loading conditions of elastic elements to real by transferring transverse forces to them.

Дл достижени поставлеЕПЮй цели опорный узел выполнен в виде корпуса, один конец которого снабжен удлинителем св занным щаровым шарниром с верхней частью рамы, а в полости корпуса смонтирозан несущий возбудитель, вал, св занный гибкой передачей с приводным двигаа лем, причем в нижней части рамы выполнено окно дл установки фиксатора вала возбудител , а последней размещен в этом окне с возможностью перемещени .To achieve the goal, the support unit is made in the form of a body, one end of which is provided with an extension of a connected ball joint with the upper part of the frame, and a carrier pathogen, a flexible transmission with a drive motor, is mounted in the body cavity, and the lower part of the frame is made the window for installing the exciter shaft lock, and the latter is placed in this window with the possibility of movement.

На фиг. 1 изображен стенд дл испытани пружинных упругих элементов в рабочем состо нии без фиксатора, вид спереди; на фиг. 2 - то , в момент установки испытуемых упругих элементов; на фиг. 3 - то же, вид сверху.FIG. Figure 1 shows a test bench for spring elastic elements in an operating state without a lock, front view; in fig. 2 - at the time of installation of the test elastic elements; in fig. 3 - the same, top view.
