    In a hinge unit which connects the members of articulated power vehicles such as tractors and which permits mutual pivotal movements of such members about a vertical and a horizontal axis, a front member is attached to a forward portion of the vehicle and a rear member is attached to a trailing portion of the vehicle while the front member and the rear member are interconnected by an intermediate member which is supported by a pair of bearings defining a vertical axis on the front member and by another pair of bearings defining a horizontal axis on the rear member, all three members forming together a universal or cardan joint.

    (54) HINGE CONNECTION FOR MAGNETIC TRANSPORT FACILITIES
    hinges in one direction only.
    Figure 1 shows an articulated vehicle equipped with a swivel, front view; Fig.2 swivel, front view; in FIG. 3, a top view of phi1% 2. in FIG. 4, section A-A of FIG. 3 in FIG. 5 - hinge with vertical rotation; in fig.chb - hinge with a horizontal axis of rotation; figure 7 - section bb fig.Z.,
    The articulation 1 is mounted on an articulated vehicle 2, which consists of a front 3 and rear 4 sections.
    To rotate the section, there is a pair of control cylinders 5, each of which has a piston rod 7 or 8. The cylinders 5 and b are connected by means of hinged fingers 9 and 10 with a pair of brackets 11 and 12. The outer ends of the rods 7 and 8 are hingedly connected by pivot pins 13 and 14 with brackets 15 and 16.
    Swivel 1 consists of front 17, rear 18 and intermediate 19 links, which are interconnected by hinges with a vertical axis of rotation. Y - Y and hinges with a horizontal axis of rotation Х-х.
    For the suspension of intermediate link 19 in the front link 17 and in the back link 18 there are ball joints that are arranged in pairs along the axes X-X and U-Y. Two noBOHPOTHfja supports 20 and 21 (Fig. 4) are located along the axis U-U and are attached to the brackets 22 and 23 on link 17. Along the horizontal axis X-X, rotary supports 24 and 25 are provided, with the support 24 being supported by the bracket 26 rear link 18, and the support 25 is installed in the housing of the rear link 18.
    The pivot pin 27 carries the sleeve 28, which with the bracket 29 of the intermediate link 19 encloses the ball joint 30. The ball joint 30 is fixed in its position by means of the plug 31. The axial forces are transmitted through the arm 32 of the bracket 29 to the ball joint 30, as it is on the sleeve 28. The sleeve 28 rests on the cold 33, which has an inwardly protruding edge 34. The edge 34 interacts with the edge 35 of the hexagon section 3 of the rotary
    gi
    fingers 27. Distance
    between the bracket 22 and the sleeve 28 and between the edge 35 and the edge 34, provide corresponding gaps preventing the simultaneous loading of both pivot bearings 20 and 21 with axial forces.
    Swivel bearing 24 is made almost the same with swivel bearing 20. Gasket 37 together

     The load of the swivel bearing 24 only in one direction. The opposing rotary support device 25 acts in the opposite direction.
    О The front link 17 is integral with section 3, and the rear link 1B is detachable — and secured to section 4 with screws 38. To the lower end of intermediate link 19
    5 along the vertical axis V-V is hingedly attached with a swivel pin 39 tons ha 40. The other end of the string 40 is fixed on the lower part of the rear section 4. Such a coupling has a double advantage. On the one hand, the hinge joint 1 is discharged from acting horizontal tensile forces. On the other hand
    c tensile forces act on the hinge joint 1 along the vertical axis of the Y-Y so that they cannot cause turns that would adversely affect the control of the articulated transport
     means.
    On the front section 3 and on the rear section 4 at an angle of 30 to each other, stop surfaces 41 and 42, 43 and 44 are made to restrict reciprocal rotary movements around the vertical axis U-Y. Similar thrust surfaces may be provided.
    0 to limit the relative rotation of the sections around the horizontal axis X-X.
    Swivel works as follows.
    c. Suppose that an articulated vehicle 2 is moving forward on a flat surface, with the hinged connection 1 with sections 3 and 4 in the position shown in Fig. 3 with solid lines. When the articulated vehicle 2 moves over uneven terrain and its right front wheel hits the corner. lambing then front section 3
     rotates around a horizontal axis X-X relative to the rear section 4. This position is shown in FIG. 7. While the front section makes this pivotal
    0 moving, the intermediate link 19 of the hinge 1 makes only a simple turn around the horizontal axis X-X in the counter-clockwise direction, without any influence
    5 way to control cylinders
    5 and b either to the rear section 4 of the vehicle.
    On the other hand, sections 3. and 4 can rotate horizontally relative to each other around the vertical axis U-U, and the vertical axis U-U also passes through an imaginary point of intersection with the axis X. When driving, cylinders 5 and b are pushed due to the steering wheel in the driver’s cab. or retract. If the steering wheel is turned to the right, then the control cylinders provide for turning sections 3 and 4 against each other, in which the articulated vehicle 2 makes a right turn.
    The vertical axis V-V of all rotations passes through an imaginary intersection point, so that it does not have any effect on the mutual deviations of sections 3 and 4 around the horizontal axis XX.
    The described joint is compact, lightweight, low cost and allows all sections to be rotated relative to each other, driven by uneven terrain — or control with a minimum length of power levers, which ensures reliable operation and efficient use of forward 1Pl.
