Abstract

The invention relates to railway transport, in particular to articulated mine locomotives. The purpose of the invention is to reduce dynamic loads and increase stability. The mine locomotive contains a head section 1, a tail section 2 and a middle section 3. The frame 4 of the middle section 3 rests on the frame of section 1 through a double hinge with mutually perpendicular axes, and on section 2 through a hinge with a vertical axis. The sections are supported on two biaxial carriages 12, each of which has a longitudinal balance bar 13, pivotally connected to the bracket 15 of section 1 or 2, with the ends supported through springs 17 on the axle boxes. The bushings are connected to the bracket by 15 drivers, which have the possibility of angular movement relative to their axis and some longitudinal movement. On the frame 4 of the middle section 3, a transverse beam is pivotally fixed on which section 3 is supported at one end. When moving in curvilinear sections of the path, transverse forces cause section 1 or 2 to rotate relative to frame 4 around the vertical axes of the hinges and around the horizontal axis, thereby maintaining its horizontal position middle section 3. When moving along a track with excess of one of the rails, the load is equalized due to the operation of the springs 17 and rotation of the driver body together with the axle box relative to the bracket 1 or 2.

The invention relates to railway transport, in particular, to the design of articulated mine locomotives.

The purpose of the invention is to reduce dynamic loads and increase stability.

FIG. a mine locomotive is shown, general view; figure 2 - node I in Fig .; in FIG. 3, node P in FIG. figure 4 - section aa in figure 1; figure 5 - connection of the longitudinal balancer with the axle box; figure 6 - view B in figure 1.

The mine locomotive contains the head section 1, the tail section 2 and the middle section 3 of the Frame 4 of the medium section 3 is supported on the frame of the head section 1 by means of a double hinge 5 consisting of a horizontal pin 6 mounted rotatably in the lugs 7 of the vertical support 8, the vertical finger of which is movably positioned in the insert 9 of the frame of the head section 1. The frame 4 rests on the frame of the tail section 2 by means of a vertical guy 10 hinged in the cylindrical insert 11. The middle section 3 is a set 4 power unit mounted on the frame. Sections 1 and 2 of the locomotive rest on two biaxial trolleys 12, each of which has a longitudinal balance bar 13, the middle part of the hinge 14 connected to the frame bracket 15 of section 1 or 2, and the ends of the wheel pairs 16 supported by springs 17, the upper spots 18 and lower heels 19 and an intermediate element 20 by a balance bar The mating surfaces of the upper heel 18 and intermediate element 20 are spherical.

The axleboxes 16 wheel pairs are connected to the brackets 15 by the drivers 21, which are made as follows. The hollow cylindrical body 22 is rigidly connected to the body of the axle box 16, on the other hand it is fitted with a cap nut 23, abutting with an annular elastic element 24 into the shoulder 25 of the axis 26 placed inside the body 22. From the side of the box into the body 22 coaxially axis 26 is inserted with the possibility of rotation of the finger 27. Between the ends of the finger 27 and the axis 26 is placed the elastic element 28. Opposite

the end of the axis 26 is connected by the hinge 29 to the frame bracket of the head section 1 or 2.

On the frame 4 of the middle section 3, the hinge 30 is fixed to the transverse beam 31, on which the power unit is supported.

The mine locomotive operates as follows.

When moving in a curved section of the path, the transverse forces between the wheels and the rails cause the head section 1 and the tail section to turn

5 2 relative to the frame 4 of the middle section 3 around the vertical, axes of the hinges 5 and 10 and rotate around the horizontal finger 6, thereby maintaining the horizontal position of the middle section and aligning the vertical reactions in the hinges.

When moving along a track with the excess of one of the rails, the loads are equalized due to the operation of the springs 17 and the rotation of the housing 22 relative to the pin 27 and the axis 26.

Placing the middle section 3 with one end on the yoke 31 provides three-point support of its frame 4, and therefore, sections I and 2 when moving along the track with imperfections.
