Definitions
- the present invention relates to a system for controlled tipping of a dump body of a transport vehicle, such as the dump body of a truck.
- Load-carrying bodies of transport vehicles such as truck bodies, rest on the chassis at least at four support locations, substantially at the vertices of the bottom face of the load-carrying floors of the bodies.
- Each support location has two mutually engageable support and elements, namely a convex element which is fixed to the frame by a horizontal shank and extends therefrom in cantilever fashion thereby forming a spherical head supported by the shank, and a substantially inverted cup-shaped concave element, which is fixed to the bottom surface of the floor of the body and is designed to accommodate the spherical head by receiving it therein for complete support.
- a convex element which is fixed to the frame by a horizontal shank and extends therefrom in cantilever fashion thereby forming a spherical head supported by the shank
- a substantially inverted cup-shaped concave element which is fixed to the bottom surface of the floor of the body and is designed to accommodate the spherical head by receiving it therein for complete support.
- the concave element has a slightly flared inlet opening for easy introduction of the spherical head therein and a straight longitudinal notch formed in the outer surface of the inverted cup for passage of the shank during introduction and removal into and from the spherical head.
- Both the spherical head and the inverted cup have respective through holes, which are mutually aligned when the body is in its normal horizontal position, for receiving respective locking bolts that prevent separation thereof.
- the driver may select the lateral side or the back side through which the material has to be dumped, and may operate in either of two different ways.
- the driver must also release the hooks, if any, that are typically provided between the dump floor of the body and the bases of its walls, to hold the latter in the vertical payload-retaining position.
- MO201 0A000033 by the applicant hereof, discloses a tipping system that provides automatic bolt insertion/removal using respective electric actuators connected to a control unit that moves them between the engaged and disengaged positions.
- a signal is generated, which is sent to a receiving device disposed in the driver's cab and enables the driver to start tipping the body toward the selected side, opposite to the side in which the bolts are engaged.
- a first drawback of this arrangement is that the bolts slide out of the chassis frame and, in the operating position, tend to be exposed to shocks or damage.
- a further drawback is that the electrical connections of the actuators with the control unit are at least partially arranged on the vehicle body.
- a further drawback is that, in the locked body position, the bolts extend through the spherical body and beyond to a short length which substantially corresponds to the thickness of the walls of the bell elements in which the holes have been formed.
- the technical problem addressed by the present invention consists in providing a system that affords automatic and safe tipping of the dump body of a vehicle and is very simple.
- the object of the present invention is to obviate the above drawback, by providing a system for controlled tipping of a dump body of a vehicle.
- Another object of the present invention is to provide a system as described above that affords automatic and safe tipping of the dump body of a vehicle.
- a further object of the present invention is to provide a system as described above that can prevent damages to mechanical and electronic parts.
- Another object of the present invention is to provide a system as described above that has lower complexity and a smaller size.
- Yet another object of the present invention is to provide a system as described above that affords simpler disassembly and removal of the dump body.
- Another object of the present invention is to provide a system as described above that provides stable support to the dump body of the vehicle as it moves.

- each actuator 21 is accommodated in a recess 1 1 , 1 2 of a cross member 6, 7 at a respective support means 1 5A, 15B, 1 5C, 1 5D for actuating the respective pin 20 along a transverse direction X and cause the convex element 16 and of the concave element 1 8 to be locked together when the body 2 does not have to be tipped.
- each convex element 16 comprises a securing base 24 for fixation to the bottom face 2' of the body 2 and a connecting segment 25 between the base 24 and the spherical head 1 7.
- the concave element 1 8 may comprise a mating cup-shaped body 26, which defines the seat 1 8 for the spherical head 17 and has a side portion 27 for fixation to the counter frame 5, particularly to the support flanges 9, 1 0 of the cross members 6, 7.
- Each pin 20 and each stem 22 have such overall lengths as to allow the pin 20 to extend along the entire seat 1 9, as shown in FIGS. 4 and 5, by fitting into a first through hole 28 formed both in the flanges 9, 1 0 and in the side portion 27 of the cup-shaped body 26 and extending to engagement of an opposed second hole 29 coaxial with the first hole 28 and formed in the wall 30 opposite to the flange 9, 1 0 of the cup-shaped body 26.
- a first antifriction and sealing bush is fitted into the first hole 28, to facilitate a guided sliding motion of the pin 20 while preventing any infiltration of debris and dust into the receptacle 1 9.
- a second axially hollow cylindrical bush 32 is fixed on the wall in the coaxial extension of the second hole 29, and if needed, can reach the end of the pin 20 when the latter engages the hole 29 to push or pull it as needed.
- each spherical head 1 7 of each convex element 1 6 may comprise a pair of diametrically opposite slots 33, 34, which are connected together by a hole 35 for the passage of the respective pin 20.
- One of the eyelets 33 is formed on the outer surface portion
- the two eyelets33, 34 are substantially identical, but extend in opposite directions from the center of the spherical head 1 7, and namely the one that faces away from the flanges 9, 1 0 extends toward the securing base 24 and the other, that faces toward the flanges 9, 1 0, extends in a vertically opposite direction.
- the eyelets33, 34 of the spherical heads 1 7 of one side of the body 2 are disengaged from the pin 20 when the body 2 has to be tipped to the opposite side, to allow the spherical heads 1 7 to freely come out of the respective bodies 26 on the same side of the body 2.
- the four support means 1 5A, 1 5B, 15C, 15D are formed as described above and their respective eyelets33, 34 are oriented in pairs outwards at opposite sides of the body 2.
- the convex element 1 6 is able to rotate within the concave element 1 8, once they have been locked by the pin 20 in one direction of rotation, or alternatively in two directions of rotation.
- the system 1 comprises anuser-operable electronic control unit 36 connected to the actuators 21 and to the lift cylinder 8, and a pluOrality of position sensors 37.
- the sensors 37 may be associated with the actuators 21 for detecting the relative position of the stems 22 and pins 20 and also the underrun protection bar 14 may be connected to the control unit 36 for selective actuation and may be associated with a respective position sensor 37.
- control unit 36 affords independent actuation of the actuators 21 of the support means 1 5A, 1 5B, 15C, 1 5D and the underrun protection bar 14.
- connection of the control unit 36 with the actuators 21 and the underrun protection bar 14 is obtained by means of respective electrical connections 38, which are integrally arranged on the counter frame 5 of the vehicle 3.
- This configuration has the advantage of allowing the body 2 to be removed while preventing disconnection of the electrical connections 36, with the possibility of kinematically reversing the position of the convex element 1 6 and the concave element 1 8 with respect to the body 2.
- the control unit 36 may comprise a user-operable control terminal 39 which is connected to an electronic control board 40.
- the terminal 39 is located within the driver's cab 1 3.
- the terminal 39 may be configured to allow, by selective actuation of one or more controls, the lift cylinder 8 to only move when two of the four pins 2 are in the locked position, according to the tipping side.
- control terminal 39 is configured to only allow actuation of the lift cylinder 8 when the rear support means 1 5C, 1 5D are in the locked position and when the underrun protection bar 14 is in the rest position.
- control terminal 39 may also have additional features and be configured to prevent actuation of the lift cylinder 8 when the emergency brake of the vehicle 3 is not activated or when the power take-off is not engaged.
- the control terminal 39 can also control the opening movement of the hydraulic walls of the body 2 according to the selected tipping side and warns the driver, by means of appropriate light signals, about any system faults. The nature of these faults may be investigated by the driver by actuation of a predetermined sequence of controls.
- control unit 36 does not allow the lift cylinder 8 to be actuated if the pins 1 5A and 1 5D selected for the locked position are not fully inserted in their respective spherical heads 1 7 and cup-shaped bodies 26.
- the spherical heads 1 7 of the two rear support means 1 5c, 15D will both rotate around their respective pins 20, which are substantially coaxial and engage them with their respective cup- shaped bodies 26 transverse to the axis Y.
- the present invention may find application in industry, because it can be produced on an industrial scale in factories operating in the field of vehicle safety, particularly for trucks.
