Изобретение относитс к технике измерени параметров взаимодействи опорных элементов транспортных средств с поверхностью, например , дорожных покрытий и может быть использовано дл проведени исследований автомобильных и авиационных колес, гзсениц, лыж и т. п., тормозных систем, а также при проектировании и строительстве дорог и покрытий аэродромов.The invention relates to a technique for measuring the parameters of the interaction of vehicle support elements with a surface, such as road surfaces, and can be used to conduct studies of automobile and aviation wheels, curtains, skis, etc., brake systems, as well as in the design and construction of roads and airfield coatings.
Известно устройство дл исследовани взаимодействи колеса с поверхностью дорожиого покрыти , выиолненное в виде прицепа, шарнирно соедин емого с транспортным средством и снабженного испытуемым колесом с тормозом, балластным грузом и датчиками.A device is known for studying the interaction of a wheel with a road surface, made in the form of a trailer pivotally connected to a vehicle and equipped with a test wheel with a brake, ballast weight and sensors.
У такого устройства в режиме торможени испытуемого колеса возникает пропорциональный силе торможени реактивный разгружающий момент, в результате которого вертикальна сила на колесе умеиьшаетс , что ускор ет технику эксперимента и точность и достоверность результатов.In such a device, in braking the test wheel, a reactive unloading moment proportional to the braking force occurs, resulting in a vertical force on the wheel that decreases, which accelerates the experimental technique and the accuracy and reliability of the results.
Известно также устройство, содержащее прицеп с балластным грузом, параллелограммный механизм, соедин ющий прицеп с т гачом , стойку, св занную с испытуемым колесом, и тормоз. В этом устройстве дл св зи прицепа с транспортным средством применен параллелограммный механизм.It is also known a device comprising a trailer with a ballast weight, a parallelogram mechanism connecting the trailer with a wrench, a strut associated with the test wheel, and a brake. This device uses a parallelogram mechanism to link the trailer to the vehicle.
Однако измерительна часть устройства позвол ет определить коэффициент сцеплени колеса с дорожным покрытием путем вычислени его на ociiOBaHHH измерений сил, действующих на колесо, например силы трени , и вертикальной нагрузки.However, the measuring part of the device allows determining the coefficient of adhesion of the wheel to the road surface by calculating it on the ociiOBaHHH of measurements of forces acting on the wheel, such as friction forces, and vertical loads.
Цель изобретени - упрощение измерени коэффициента сцеплени колеса с дорожным покрытием и действующих на колесо сил.The purpose of the invention is to simplify the measurement of the adhesion coefficient of a wheel with a road surface and forces acting on a wheel.
Эта цель достигаетс тем, что стойка соединена с осью колеса и тормозом посредством второго параллелограммного механизма, на рычагах которого установлены сплоизмерительные датчики, например тензодатчики, и датчик угла поворота одного из рычагов относительно стойки.This goal is achieved by the fact that the stand is connected to the wheel axis and the brake by means of a second parallelogram mechanism, on the levers of which there are mounted measuring sensors, for example strain gages, and a rotation angle sensor of one of the levers relative to the stand.
На фиг. 1 изображена схема устройства; на фиг. 2 - схема действующих на колесо сил.FIG. 1 shows a diagram of the device; in fig. 2 - diagram of the forces acting on the wheel.
Устройство представл ет нрицеп, буксируемый транспортным средством. Основным силовым элементом прицепа вл етс балка 1, служаща рычагом параллелограммного механизма . Передним концом балка 1 щариирно соединена с транспортным средством, на другом , например, консольном конце зкреплен балластный груз 2. Па заданном минимально возможном рассто нии от переднего конца балки шаринрно к ней ирнсоедннена вертнкальна стойка 3, другим концом щарнирноThe device is a trailer towed by a vehicle. The main power element of the trailer is beam 1, which serves as a lever for a parallelogram mechanism. The front end of the beam 1 is bolted to the vehicle, on the other, for example, the cantilever end, the ballast weight 2 is attached. Pa of the specified minimum possible distance from the front end of the beam is attached to the vertical strut 3, the other end of the hinge
