The invention relates to road transport, in particular for tipper vehicles, and relates to a device for tipping the body.Known vehicle that contains a frame, a tilting body and the hydraulic lift cylinder, the rod of which is pivoted beam, one end of which is pivotally connected with the of the body.Known tipper vehicle containing a frame pivotally mounted on the tilting her body, lifting cylinder, one end of which is pivotally mounted on the frame, and the other hinge on the two shoulders lever fixed the hinge on the bottom of the body 
The disadvantages of this device are:
limited angle of tilting of the body;
large maximum length of the cylinder.The technical result of the invention is to increase the angle of tilting of the body and the reduction of the maximum length of the lifting cylinder.The technical result is achieved in that in a dump vehicle, containing a frame pivotally mounted on the tilting her body, lifting cylinder, one end of which is pivotally mounted on the frame, and the other hinge on the two shoulders lever fixed the hinge on the underside of the vehicle, two shoulders lever is made with different shoulders arranged at an obtuse angle to each other, and a lower shoulder is facing down and with emphasis in the bottom of the body, and on a larger shoulder placed swivel cylinder and an elastic element, one end of which is secured to the specified shoulder, and research institutes; in Fig. 2 is the same, at the time of tilting of the body on an angle, ensuring the establishment of overturning moment of the elastic element of Fig. 3 - the same, when the tilted body.Tipper vehicle includes a frame 1, on which 1 pivotally mounted tilting the body 2. On the frame 1 hinged at one end has a lifting cylinder 3, and the other end articulated on the two shoulders of the lever 4. Two shoulders lever 4 pivotally mounted on the underside of the vehicle 2 and is made with different shoulders arranged at an obtuse angle to each other. A smaller lever arm 4 is directed downward and serves as a stop for the bottom of the body 2 in the tilted position. A greater lever arm 4 is placed along the bottom of the body 2 in the middle part. On a larger shoulder placed swivel cylinder 3 and the lever 4, and also has an elastic element 5. The elastic element 5 is placed in a recess made on a larger lever arm 4. One end of the elastic element 5 is fixed on the lever, and the other on the bottom of the body 2. The elastic element may be in the form of a spring.The vehicle operates as follows.At the initial moment of the force on the cylinder 3 forms a tilting moment about the axis of hinge krepline /Fig. 2/ elastic element creates an additional overturning moment, which leads to further tilting of the body 2 /of Fig. 3/ without increasing the length of the hydraulic cylinder 3. The maximum angle of tilting is provided by the position of the small lever arm 4 and the bottom of the body 2. The resistance body 2 in the tilted position is ensured by the mutual location of the small lever arm 4 and the bottom of the body 2 on the one hand and the maximum length of the lift cylinder 3 on the other, where the connection of the hydraulic cylinder 3 to the wheel 2 through a greater lever arm 4. Bringing the body 2 to its original position in the reverse order. The initial position of the elastic element 5 is provided with a weight body 2. Tipper vehicle containing frame, hinge, mounted on the tilting her body, lifting cylinder, one end of which is pivotally mounted on the frame, and the other hinge on the two shoulders lever fixed the hinge on the underside of the vehicle, characterized in that the two shoulders of the lever is made with different shoulders arranged at an obtuse angle to each other, and a lower shoulder is facing down and with emphasis in the bottom of the body, and on a larger shoulder Reece, and the other on the underside of the vehicle.
