Abstract

Invention concerns the improvement of mine locomotives, in particular, connecting units between wheel carts, articulated with average section. Each connecting unit contains vertically located cylindrical hinge, on finger of which in the middle part is fit an elastic element in the form of a tore. The groove is provided for this purpose on the finger in the housing of hinge repeating the shape of the tore. Elastic element in the form of a tore ensures relative displacement of cart and average section in all planes. In this case, it absorbs jolts and shocks of different directions.

Description

Description of the invention

The proposed invention relates to the field of means of rail transport, in particular 2 connecting elements of mine locomotives.

A vehicle bogie is known, containing two half-frames resting on the wheel pairs through elastic elements. To compensate for the angular movements of the half-frames relative to the cart axis when driving on curves, the cart rail is equipped with additional elastic elements. The connection is made in the form of a U-shaped horizontal beam, which is connected to one half-frame by means of a horizontal longitudinal 70 hinge, and to the other - by vertical pins. The disadvantage of such a constructive solution is the possibility of mutual movement of half-frames only in two planes: horizontal and vertical. patent OA 6142 Vb1E5/121.

A well-known mining locomotive (prototype) containing two wheeled carts articulated with a middle section containing a power unit. The articulation unit of each carriage with the middle section includes a power hydraulic cylinder. It is hinged at one end to the cart, and at the other end also hinged to the upper end 12 of the vertical finger. The latter is connected to the middle section by means of a spherical joint, and the lower end is connected to the carriage by means of a cylindrical joint.

One of the shortcomings of this connection of sections is that the spherical joint dampens system oscillations directed from the center of the sphere down, as it is an open-type element. In addition, the hinge has the same stiffness in all directions, which limits the degree of freedom of the locomotive on difficult sections of the track, patent OA 4398,

The basis of the invention is the task of improving the mine locomotive, in which, by means of a different design of the connecting node, an increase in the degree of freedom of the mine locomotive is ensured, and due to this, system oscillations in all directions are compensated, resistance is reduced on difficult sections of the track while the dimensions of the hinge are reduced. p. 29 Due to all of the above, the operating conditions of the locomotive are improved, the resistance to movement along the rails is removed, the conditions for fitting into curves of small radii are improved, the speed of the locomotive is increased and, therefore, productivity is increased.

The problem is solved by the fact that in a known mining locomotive, which contains two extreme carts with wheel pairs and a middle section articulated with them by means of a connecting node, according to the invention (7 30 the connecting node has an elastic element in the form of a torus, worn on the axis of a cylindrical hinge, in the body of which a recess is made for placing a torus that repeats its shape.

The figure shows a section of the joint, where: o 1. finger joint; c 2. elastic element in the form of a torus of constant or variable cross-section; 3o Z. hinge body; o 4. cart; 5. middle section;

The intended mine locomotive contains two wheeled bogies articulated with a middle section. The node of articulation of each carriage with the middle section includes a cylindrical joint with a vertical Z 50 position of the axis (hereinafter referred to as the finger). An elastic element in the form of a torus is worn in the middle part of the finger. With the upper part, the finger 1 is connected to the middle section 5, and the body of the hinge C is located on the carriage 4. c» The mine locomotive with a new unit of articulation of the carriage with the middle section works as follows.

When the locomotive is moving along a straight section of the rail, the traction force from the carriage is transmitted through the body of the hinge Z to finger 1, and from it to the middle section 5. When moving on curves and on complex 45 sections of the track, the transmission of traction force occurs in the same order, but when this slightly changes the work of the hinged connection. The vertical finger 1 works like a cylindrical hinge, allowing the middle section 5 and the carriage to rotate relative to each other in the horizontal plane, and the elastic element in the form of a torus 2 allows their relative movement in all planes. This leads to a significant improvement in the dynamic properties of the entire locomotive in general: shocks are softened, breakdowns, cracks in parts are reduced, av! 20 increases their resistance to triggering. In addition, to move the locomotive on particularly difficult sections of the track, it is advisable to make the elastic element in the form of a torus 2 with a variable cross-section. At the same time, different stiffness is achieved in different directions (longitudinal and transverse).

Also, the design of a hinge with an elastic element in the form of a torus is always more compact than a spherical one. It works more reliably, as it is an element of a closed type. Thanks to this, the hinged connection with an elastic element in the form of a torus reliably dampens vibrations in all directions, including vertical
