Description
Изобретение относитс к области исследовани т гово-сцепных качеств транспортных средств.The invention relates to the field of research of the go-coupling qualities of vehicles.
Известно устройство дл измерени динамических нагрузок на колесо, устанавливаемое на протекторе шины, в которое может быть встроен испытуемый .шип 1. Однако сложность передачи сигналов усилий на регистрирующую аппаратуру «е Обеспечивает качества испытаний.A device for measuring dynamic loads on a wheel mounted on a tire tread into which test subject 1 can be embedded is known. However, the complexity of transmitting force signals to recording equipment provides the quality test.
Наиболее .близким к предлагаемому вл етс устройство дл испытани шипоз противоскольжени , содержащее корпус с размещенными В нем механизмом нагружени и креплени щипа и тензоизмерительными элементами 2.Closest to the present invention, there is a device for testing anti-skid spikes, comprising a housing with a loading and anchoring mechanism and strain gauge elements 2 accommodated therein.
Недостатком этого устройства вл етс выполнение контактирующей поверхности в виде имитатора обледенелого грунта, а кинематика взаимодействи шипа с опорной поверхностью не соответствует его действительной работе. Испытание шипов противоскольжени известным устройством требует больших затрат труда на подготовку опорной поверхности и не обеспечивает качества эксперимента .A disadvantage of this device is that the contacting surface is in the form of a simulator of icy soil, and the kinematics of the interaction of the spike with the bearing surface does not correspond to its actual work. Testing of anti-slip studs with a known device requires a lot of labor for preparing the bearing surface and does not provide the quality of the experiment.
С целью сокращени трудоемкости и повышени качества испытани корпус предлагаемого устройства снабжен фланцем дл установки на ступице колеса транспортного средства и механизмом замера касательных усилий , .выполненным в виде вилки с роликом и тензоэлементом; механизм нагружени выполнен в виде подпружиненного через тензоиЗМерительный элемент штока, подвижного вдоль своей оси и в плоскости па.раллельной колесу, передающего касательные усили на тензоизмерительный элемент через вилку с роликом.In order to reduce the labor intensity and improve the quality of the test, the body of the proposed device is equipped with a flange for mounting on the wheel hub of the vehicle and a measuring mechanism for tangential forces, made in the form of a fork with a roller and a strain element; the loading mechanism is made in the form of a rod, spring-loaded through a strainer and a measuring element, moving along its axis and in the plane of a parallel wheel, transmitting tangential forces to the strain-gauge element through a fork with a roller.

Кроме того, с целью предотвращени поломки тензоизмерительного элемента подвижный щток снабжен ограничителем хода, выполненлым в виде опорной пластины.In addition, in order to prevent breakage of the strain gauge element, the movable brush is provided with a travel stop made in the form of a support plate.
На фиг. 1 изображено предлагаемое уст5 ройство, вид спереди; на фиг. 2 - то же, вид сбоку.FIG. 1 shows the proposed device, front view; in fig. 2 - the same, side view.
