Изобретение относитс к средствам дл испытани транспортных средств и может быть использовано при исследовании взаимодействи движителей транспортных средств с грунтом.The invention relates to means for testing vehicles and can be used in the study of the interaction of vehicle propulders with the ground.

Известно устройство дл измерени глубины погружени опорной поверхности транспортного средства в грунт, содержащее корпус , подвижный элемент, штангу и датчики перемещени 1.A device is known for measuring the depth of immersion of a vehicle support surface in the ground, comprising a housing, a movable element, a rod and displacement sensors 1.

Это устройство позвол ет производить измерение общей глубины колеи за движущимс транспортным средством, образовавщейс при перекатывании по опорной поверхности гусеничного движител всех катков одного из бортов машины. Однако его функциональные возможности ограничены ввиду необходимости изготовлени такого устройства дл каждого типа гусениц и невозможности его использовани дл исследовани самого процесса образовани колеи как гусеничным, так и колесным движител ми .This device makes it possible to measure the total depth of the track following a moving vehicle, which is formed when the track rollers of all the rollers of one of the sides of the machine roll over the bearing surface. However, its functionality is limited due to the need to manufacture such a device for each type of track and the impossibility of using it to study the process of formation of a track by both track and wheel drives.

Цель изобретени - расширение функциональных возможностей устройства.The purpose of the invention is to expand the functionality of the device.

Поставленна цель достигаетс тем, что подвижный элемент выполнен в виде плитыThe goal is achieved by the fact that the movable element is designed as a slab

с датчиками давлени , корпус закреплен на грунте и оснащен подвижной кареткой, на которой закреплена одним концом штанга, другой конец которой св зан с плитой. На фиг. 1 - устройство, общий вид;with pressure sensors, the housing is fixed to the ground and equipped with a movable carriage on which one end of the rod is fixed, the other end of which is connected to the plate. FIG. 1 - device, general view;

5 на фиг. 2 - схема установки устройства. Устройство состоит из корпус 1, в котором перемещаетс подвижна каретка 2, представл юща собой два соединенных между собой параллельных стержн 3. Ка ,Q ретка перемещаетс в направл ющих 4 и 5, соединенных с корпусом 1. Кроме того, подвижна каретка 2 снабжена датчиком 6 перемещени , закрепленным на корпусе 1, с ней соединена щтанга 7 с наклонным стержнем 8. Корпус 1 устройства с помощью5 in FIG. 2 - device installation diagram. The device consists of a housing 1, in which a movable carriage 2, which is two interconnected parallel rods 3, is moving. Ka, Q, the rotor moves in guides 4 and 5 connected to the housing 1. In addition, the movable carriage 2 is equipped with a sensor 6 mounted on the housing 1, it is connected to the pole 7 with an inclined rod 8. The housing 1 of the device using

15 анкеров 9 устанавливаетс на грунт р дом с предполагаемой колеей транспортного средства. Стержни 3 каретки 2 соединены между собой при помощи соединительных штанг 10. Возвращение каретки 2 в исход2Q ное положение и обеспечение ее поджати осуществл етс пружинами 11, установленными между кареткой 2 и корпусом 1.15 anchors 9 are installed on the ground adjacent to the estimated vehicle track. The rods 3 of the carriage 2 are interconnected by means of connecting rods 10. The carriage 2 returns to its initial position and is pressed against the springs 11 installed between the carriage 2 and the body 1.

Claims

Each of the axes of the movable carriage is equipped with forks 12 and 13 with bearings 14. Bearings 14 are installed at an angle of 90 ° to each other in order to avoid skewing of the carriage 2 when moving in housing 1. At the end of the rod 8 of the rod 7 there is a support plate 15 mounted on it pressure sensors 16. The device works as follows. Before conducting experimental studies on the measurement of the immersion of the vehicle ground surface into the ground, the device is mounted on the ground with the help of anchors 9 so that the plate 15 is located in the strip of the intended passage of the vehicle. When interacting, the drive with the plate 15 is last moved downward and pressed into the ground alternately by each support roller. In this case, the rod 7 moves the carriage 2, thereby compressing the springs I. The displacement of the carriage 2 relative to the body 1 is proportional to the immersion of the plate 14 into the ground, i.e., the track depth, and is detected by the displacement sensor 6 located on the device body i. The pressure sensor 16 is used to determine the plot of the normal pressure from the support rollers and their position at the time of gauging the depth of the track of the moving vehicle. The registration of measured values is performed automatically in the vehicle running process. The application of the present invention allows a more accurate study of the process of the formation of the track of a moving vehicle under each support roller, and also expands the boundaries of the speed of movement of the machine to select the optimal design of the propulsion elements, which makes it possible to significantly extend its area of application. Apparatus of the Invention A device for measuring the depth of immersion of a vehicle support surface in a ground comprising a housing. movable element, shtanga and displacement sensors, distinguished by the fact that, in order to expand the functionality of the device, the movable element is made in the form of a plate with pressure sensors, the body is fixed on the ground and equipped with a movable carriage on which is fixed one end of the shtanga zan with stove.
