Изобретение относитс к транспорту, а именно к прицепному подвижному составу.FIELD OF THE INVENTION The invention relates to a vehicle, namely a trailed rolling stock.

Известен прицеп, снабженный поворотными ос ми, соединенными между собой посредством т г 1.A trailer is known, which is equipped with pivot axles interconnected by means of t g 1.

Недостаток этого прицепа состоит в сложности его поворотного устройства.The disadvantage of this trailer is the complexity of its turning device.

Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс другой прицеп, содержащий поворотные переднюю и заднюю оси и шарнирно соединенные с ними перекрещивающиес т ги (2J.The closest to the invention to the technical essence and the achieved result is another trailer, containing pivoting front and rear axles and intersecting pivotally connected to them (2J.

Однако этот прицеп имеет низкую плавность хода.However, this trailer has a low smoothness.

Цель изобретени - повышение плавности хода прицепа путем устранени его вли ни .The purpose of the invention is to increase the smoothness of the trailer by eliminating its influence.

Цель достигаетс тем, что прицеп снабжен охватывающими т ги пружинами и жестко соединенным с рамой прицепа цилиндром, дл размещени в нем упом нутых т г, причем последние имеют упоры, а пружины расположены между цилиндром и указанными упорами.The objective is achieved in that the trailer is provided with springs covering the springs and a cylinder rigidly connected to the frame of the trailer to accommodate said cords in it, the latter having stops, and the springs are located between the cylinder and said stops.

На фиг. 1 показан прицеп, вид снизу; на фиг. 2 - то же при повороте влево; на фиг. 3FIG. 1 shows a trailer, bottom view; in fig. 2 - the same when turning left; in fig. 3

тоже, вид сзади; на фиг. 4 - узел креплени поворотного устройства к рулевой оси прицепа .also, rear view; in fig. 4 shows a pivot attachment unit to the steering axle of the trailer.

Прицеп содержит поворотные переднюю 1 и заднюю оси 2 колес, на которых установлены рессорные элементы 3. Рессорные эле менты 3 контактируют с сегментами 4, жестко закрепленными на кузове 5. К кузову 5 жестко присоединен цилиндр 6, внутри которого размещены т ги 7, средн часть которых выполнена в виде полуцилиндров 8. МежIQ ду т гами 7 установлена плоска пружина 9. На т гах имеютс упоры 10. Между упорами 10 и цилиндром 6 установлены цилиндрические винтовые пружины 11, внутри которых расположены т ги 7. Концы т г 7 выполнены в виде вилок 12, щарнирно соединен S ных с передней 1 и задней 2 ос ми колес с помощью пальцев 13. Концы т г 7, соединенные с передней 1 осью колес, выполнены скрещивающимис .The trailer contains swiveling front 1 and rear axles 2 wheels on which spring elements 3 are mounted. The spring elements 3 are in contact with segments 4 rigidly fixed on the body 5. Cylinder 6 is rigidly attached to body 5, inside which are located the 7 gi, middle part which are made in the form of semi-cylinders 8. Between IQ and arms of 7, a flat spring 9 is installed. There are stops 10 on the throats. Between the stops 10 and the cylinder 6 there are cylindrical helical springs 11, inside which are located the thrusts 7. The ends of the hg 7 are made in the form forks 12, sharnarnn GOVERNMENTAL coupled S 1 from the front and rear axles of the wheels 2 via the fingers 13. The ends of the connecting rods 7 connected with the front wheel axle 1 are made skreschivayuschimis.

К передней 1 оси колес с помощью шарниров 14 присоединено дыщло 15.To the front axle of the wheels using hinges 14 is attached to the pulley 15.

Устройство работает следующим образом.The device works as follows.

Claims

When turning the trailer, for example, to the left. (Fig. 2), the right of the ha 7 moves in the direction of arrow L, and the left in the direction of arrow B, compressing the cylindrical helical springs 11 by the stops 10 and the cylinder 6. Such movement of the rotary 7 facilitates the simultaneous rotation of the front 1 and rear axle 2 wheels on a certain angle. The movement of the middle parts of 8 tons, 7, made in the form of semi-cylinders, in cylinder 6 takes place with some resistance, since the latter are constantly unclenched by a flat spring 9. This makes it possible to obtain a stable movement of the front I and rear axles 2 when the transport means turnaround; At the same time, when the vehicle is moving in the straight-line direction, due to the presence of resistance between the thrusts 7 and the cylinder 6, the influence, twitching and pitching of the trailer are extinguished. When the vehicle influences, the movement of the tons 7 occurs along the arrows L and B (Fig. 2); the oscillations are extinguished by the helical springs 11 and the friction that occurs between the rods 7 and the cylinder 6. With longitudinal jerks, the front steering I and rear 2 axles of the wheels move at the same time along arrow C (fig. 1), the cylindrical helical spring 11 is compressed and unclenched, and since the grunt 7 moves in the cylinder with friction, the oscillations of twitching are suppressed and, consequently, the dynamic loads are not transmitted to the body 5. oscillations of the front I and rear axle 2 the wheels oscillate in the direction of arrow D (fig. 3), and since the thrust bars 7 are connected to the axles of the wheels 1 and 2, they also turn in the cylinder 6 with friction, which contributes to the damping of this type of vibration. The economic efficiency of the present invention is that a vehicle equipped with rods enclosed in a cylindrical case and moving in it with resistance, has a steady movement with simultaneous damping of three types of oscillations. At the same time, the maneuverability of such a vehicle is very high. Claim of the Invention A trailer comprising pivoting front and rear axles and intersecting intersecting pivotally connected to them: characterized in that, in order to improve the smoothness of the trailer by eliminating its influence, it is equipped with spring-loaded springs and a cylinder rigidly connected to the trailer frame, To accommodate the said tg in it, the latter having stops, and the springs are located between the cylinder and said stops.
