(57) Abstract:Use: for transportation nespokij goods. The inventive body contains a frame placed on her bottom, side, end side, and the drive rotation of the bottom. The hull is made of two parts, pivotally connected with the possibility of rotation in the transverse plane. On a frame hinged to rotate together with the bottom guides. In the past with the ability to move installed carriage. In the upper part of each side Board is made guides, which include a slider. In the middle part of one of the sections of the bottom of one end of the hinged rod, the second end of which is hinged to us the slider of the corresponding side Board. Additionally, the hinge connection of side walls and a partition plate mounted on said carriages. 3 Il. The invention relates to means of transport, in particular transport, which is used for the carriage of bulk cargoes.Known for dumping the body of the vehicle containing the frame, the rollers of which has two longitudinal polyosoma, tilting in the opposite side from the actuator (patent Germanysee dimensions.Also known dump body of the vehicle, containing a frame with stiffeners placed on her plate, made of two articulated parts, the bearing side and the lift drive plate (ed. St. N 598786, CL 61 D 9/06, 1975).The disadvantage of this body is that the center of gravity of the body with a cargo placed high from the earth's surface, which reduces the stability of the vehicle.The closest technical solution to the claimed invention should be considered dumping the body of the vehicle, containing a frame with stiffeners placed on her plate, made of two articulated parts, bearing lateral side, and a lifting drive, with each lateral side middle part pivotally attached to the rack frame, and the lower part pivotally connected with the end of the relevant part of the underbody (ed. St. N 835855, CL 60 R 1/28, 1981).The disadvantages of this body: large length of a cylinder of the lifting mechanism of the body and the low resistance of the body in the tilted position.The claimed invention is aimed at improving the efficiency of the lifting mechanism of the bottom by reducing the maximum length of selectat, which can be obtained by carrying out the invention consists of:
the decrease in the maximum length of a cylinder, due to the exclusion of the racks listed in the prototype, as well as a guide, a hinge mounted on the frame can be rotated together with the bottom;
in maintaining the required angle of tilt Paludis by placing the ends of Paludis carriages can be moved along the guide rails;
improved the stability of the vehicle when it overturned the body due to the displacement of the center of gravity of the body lower to the ground, by the use of rods and their interaction with the sidewalls, the absence of the racks listed in the prototype.Technical problem solving is achieved by the fact that the dump body of the vehicle, containing a frame placed on her plate, made of two pivotally United with the possibility of rotation in the transverse plane of the drive parts, the side of the hinged side, the hinge connected to the corresponding parts of the bottom, side and end, provided with a carriage mounted for movement in the guide, a hinge mounted on the frame can be rotated together with the plate, and rods, is alsoone, mounted in a guide made in the upper part of the corresponding lateral side, and the hinge connection of side walls and a partition plate mounted on said carriage.In Fig.1 shows the vehicle in the initial position; Fig.2 is the same, in the stage tipping body, and Fig.3, when the tilted body. On all the figures depicted vehicle, rear view.Dump body of the vehicle contains on the frame 1 of the vehicle bottom 2. The bottom 2 is made of two pivotally connected parts. The bottom is made with a possibility of rotation in the transverse plane. Rotate them by using the power cylinder 4, placed vertically on the frame 1 in the middle part, and the piston rod of the hydraulic cylinder 4 is connected with the axis of the swivel parts of the bottom 2. Side hinged side 3 pivotally connected to respective parts of the bottom 2, this connection is made in the middle part of Paludis 2. On the frame 1 set end flanges 11, 12. Each of the parts of the bottom provided with a carriage 5, the axis of which is placed at the end of the corresponding portion of the bottom 2. The carriage 5 is installed in the guide 6 can move. Napravlyauschie bottom 2 with the corresponding side-hinged flanges 3 they are equipped with rods 7, each rod one end of which is hinged in the middle part of one of the sections of the bottom 2, and the second end of the slider 8. The slider 8 is installed in the guide 9. Guide 9 is made in the upper part of the respective side Board 3. The hinge connection of the sides 3 and the partition plate 2 mounted on the carriage 5. End flanges 11, 12 may be provided with tabs 13 for engagement with side-hinged flanges 3 and the frame 1 supports 10.Tipper body works as follows. When working stroke of the cylinder 4 of the bottom 2 and turn up, turn side Board 3 (Fig. 2). While the guides 6 are rotated together with the corresponding parts of the bottom 2, and the carriage 5 is moved along the guide rails 6. Thrust 7 provide tilting of the sides 3 relative to the axis of the hinge connection of these flanges 3, parts of the bottom 2 and the carriage 5, and the slider 8 is moved in the guide 9 (Fig.3). After the discharge of the Board 3 and the bottom 2 are returned to the initial position (Fig.1) in reverse order. The efficiency of the device when bringing the body to its original position provided by the position of the sides 3 of the frame 1 (limit 10), and the angle formed is the connection ends and lateral sides with clamps 13, using extra effort. DUMP BODY of the VEHICLE, containing a frame placed on her plate, made of two pivotally United with the possibility of rotation in the transverse plane of the wire parts, side hinged side, a hinge connected with the corresponding parts of the bottom, side and end flanges, characterized in that it is equipped carriages mounted for movement in the guide, a hinge mounted on the frame can be rotated together with the plate and rods, each of which one end hinged in the middle part of one of the sections of the bottom, and the second end of the slider, which is mounted in the guide, performed in the upper part of the corresponding lateral side, and the hinge connection of side walls and a partition plate mounted on said carriages.
