Изобретение относитс к дорожнотранспортным машинам и может быть использовано дп креплени грузов на .дпиннобазных и сочлененных шасси.The invention relates to road transport machines and can be used dp mount cargo on .bag and articulated chassis.

Известно устройство дп креппени груза на шасси, содержащее переднюю и заднюю шарнирные опоры с возможностью продольного перемещени передней опоры It is known a device dp crepe the load on the chassis, containing front and rear pivot bearings with the possibility of longitudinal movement of the front support

Такое устройство снижает напр жение в грузовой платформе при передаче т гового усили от одного звена к другому . Одаакс на косогоре опрокидывающий момент от грузовой платформы передаэтс только на заднее звено шасси, переднее же не;участвует в создании востанавлмваюшего момента, а это снижает боковую устойчивость агрегата в целом.Such a device reduces the stress in the load platform when transmitting traction force from one link to another. Odaaks on the slope overturning moment from the cargo platform transfers only to the rear link of the chassis, the front one does not; it participates in the creation of the recovery moment, and this reduces the lateral stability of the unit as a whole.

При движении агрегата переднее и заднее звень шасси совершают поперечные колебани в разных фазах Однако известное устройство передает полностью поперечные колебани заднего звенаWhen the unit moves, the front and rear linkages of the chassis perform lateral oscillations in different phases. However, the known device transmits fully transverse oscillations of the rear link.

шасси на грузовую платформу что не позвол ет получать осредненного воздействи в поперечной плоскости на платформу от переднего и заднего звеньев, и, следовательно, не снижает динамические нагрузки, действующие на груз в поперечной плоскости.the chassis on the loading platform does not allow to obtain an averaged effect in the transverse plane on the platform from the front and rear links, and, therefore, does not reduce the dynamic loads acting on the load in the transverse plane.

Известно устройство дл креплени , кузова на шасси транспортного средст ва, содержащее переднюю и заднюю шарнирные опоры, одна из которых установлена с возможностью продольного перемапени 2.A device for mounting, a body on the chassis of a vehicle, comprising front and rear pivot bearings, one of which is mounted with a possibility of longitudinal re-alignment 2, is known.

Данное устройство вл етс наиболее близким к изобретению по технической сущности и достигаемому результату.This device is closest to the invention in its technical essence and the achieved result.

Claims

However, the known device transmits fully oscillations of the rear part of the frame through the hinge-transverse supports on the body, does not allow to obtain an averaged effect in the transverse plane on the cusp from the front and rear supports, and, therefore, does not reduce the dynamic loads acting on the body in the transverse plane. The circuit of the invention is to increase the stability of the vehicle and reduce the dynamic loads in the elements of the device. For this, the device is equipped with hydraulic cylinders mounted on the body and mounted on the chassis | At these sites, with each of the above-mentioned articulated bearings, there are three spherical transversely coaxially hinges, the middle of which is placed between the chassis and bodywork along the longitudinal axis of the latter, and the two extreme ones are fixed on the rods of the said hydraulic cylinders and have a Bash-Maki to interact bearing pads, with the hydraulic cylinders of each longitudinal row interconnected. FIG. 1 schematically shows a device, a general view of FIG. 2 is a line AA in FIG. one; in fig. 3 - device in axonometry. The device for fastening the body 1 on the two-link articulated chassis 2 comprises the front 3 and rear 4 pivot bearings with the possibility of longitudinal movement of the rear support. Each support consists of 3 spherical hinges 5-7 in the transverse direction. The middle hinge 5 (see Fig. 2) is installed between the chassis frame and the body along the axis of the vehicle. The extreme hinges 6 and 7 are installed between the shoes 8 and 9, which are freely supported on the chassis frame through the 1OI 11 bearing pads and the hydraulic piston rods 12 and 13. The hydraulic cylinders 12 and 13 are mounted symmetrically on the sides of the middle hinge 5 and connected hydraulically in pairs with each boards with the help of connecting pipes 14 and 15 {see fig. 3). The device works as follows. When a tilting element appears on a slope, the body will turn with middle hinges 5 and is supported by hydraulic cylinders through hinges 6 and 7. And the shoes 8 and 9 on the support platforms 1O and 11 of the chassis frame. Due to the fact that the cavities of hydraulic cylinders, located on one side, will be the same, and the effect of hydraulic cylinders on both links of the chassis will be the same. Thus, on a slope, both links of the chassis equally create a recovery moment on the body, which increases the lateral stability of the unit as a whole. The hydraulic connection between the cylinders of each boat allows the chassis links with respect to the body only to the same angles, but in different directions due to the closure of the hydraulic volume in the cylinder cavities on each side. Thus, hydraulic communication allows the body to transmit averaged lateral vibrations from the front and rear links, which reduces the dynamic loads on the body. Indeed, if the unit moves along unevenness, the chassis link is inclined to the same angle in opposite directions, then this will not cause a body roll. If one of the links in the chassis moves equally, and the others, hitting the right way & t, tilted at an angle about, then the body, which is always at equal angles to both links, tilts only 1/2 at the same direction. Consequently, the amplitude of the transverse oscillations of the body in all cases is less than the amplitude of the transverse oscillations of the links, which means less angular velocity and angular accelerations of the body. TB1 reduces the dynamic loads acting on the body in the transverse plane. The use of the invention will improve the lateral stability of the unit and reduce the loads acting on the body, and thus reduce the weight of the power elements of the chassis, body and fasteners of equipment inside the body.
