Abstract

The wheel (1) has a symmetrical double encompassing tab (6), a tread concave surface (7) and a lane (2) connected to a round-shaped concave rail head (3) of a convex contact surface (8), a skate surface (4) and a main surface (5). A deflection mechanism is provided with blocks.

Description

Wheel for the bipestana mobile material with concave rolling surface, on rounded head rail, reduced and with convex contact surface, on railways where track devices without needles and crossings are mounted ^ (*)} .

Object of the invention

The object of the invention consists of a two-wheel wheel-rail joint solution important of the railways such as the mobile material and the track superstructure; the solution allows the interaction of both in any existing track width in the state of the art or others that may be designed and created in the future in whose railways devices are installed via needles and Crossings

Background of the invention

In the state of the art of the railways the technical solution of any track gauge is known wheel-rail; the most significant feature of the wheel of the mobile material is the tab that is located on the inner side of the axis of the moving material and whose function it is to prevent the sliding of the track; the lane, although of various types, all of them are characterized by their three parts members: head, soul and skate.

Although down the lane on a stretch of track straight from the current railroad in addition to the existing wheel, could transit a moving material with a different profile wheel than the current, however, current track equipment or road detours they would prevent the passage of such material.

Two fundamental elements of the current diversion of via, as are the needles and the crossing make traffic impossible of a mobile material with a wheel profile different from the current one.

The current diversion of needles and particularly the needles and cross with special profile condition and require that the wheel profile of the moving material is unique, which It exists in the state of the art, and vice versa.

Thus the current wheel profile of the mobile material and needle profiles and cross over current track diversion represent a unique technical solution of set, of two inseparable elements, that interact mutually, there is full interdependence between them.

Cannot transit through needle diversion There is a wheel of mobile material, whose profile is different from what exists in the state of the art, of the same so that a wheel does not exist in the state of the art a deviation of needles, whose profiles of these and of the crossing are different from the existing ones.

However, in a railway network with detours track lacking needles and crossings, as might be the case particular of a railway network where detours are installed with blocks, the possibility fits and a wide perspective opens up for research and search for other new solutions wheel-rail

Advantages of the technical solution, bipestana wheel, concave, envelope rounded, reduced and convex head rail

First -

To the arrange the two tabs wheel, the stability of the material mobile during the march increases, and very particularly in the modern high-speed railways where the tolerance of track width is +2 mm / -1 mm., and the plan layout practically represents a line since the minimum radius is order of 5,000 m.

Second -

To the reduce the rolling surface of the rail, the pressure by cm2 exerted by the wheel on it increases remarkably, which affects the speed increase.

Third -

Be considerably reduces the surface of the assembly section wheel-rail and each element separately, with which reduces the weight of the wheel and rail.

Fourth -

How consequence of the third section the weight of the meter is reduced linear lane and as a result, the investments related to the superstructure of the via.

Fifth -

How result of the third section, reducing the weight of the wheel reduce the weight of the bogies and consequently reduce the weight tare of moving material and compositions and as a result of this reduces the expenses related to the manufacture of the mobile material

Sixth -

How result of the fifth section reduces the gross weight of the trains of travelers and merchandise.

Seventh -

How result of the sixth section reduces energy consumption required for the dragging of passenger trains and goods.

Eighth -

How result of the third, fourth, fifth, sixth and seventh sections the costs of the ton / km are reduced. and traveler / Km.

Description of the invention

The technical solution bipestaña wheel, concave, on rounded, reduced and convex head rail intended for railways of any existing track width in the state of the technique or others designed and built in the future where install track deviations without needles and crossings, understands:

The wheel (1) for the movable material with profile bipestana type and concave and rail (2) with profile convex and rounded and reduced head.

The skate (4) is similar to the lanes of various types existing in the state of the art and of one size approximately the same

The height of the lane (2) is less than that of the current lane and can oscillate from the height of a lane existing in the state of the art up to a minimum value (Fig. 2), passing through an intermediate value (Fig. 1).

The wheel (1) is symmetrical and is composed of two tabs (6), whose shape between them is concave; the radio in the Top wheel and rail tread are concentric; as the tab (8) moves away from the axis of the wheel (1), the radius of curvature of the flange increases.

The rolling surface (8, 7) between the two elements is less than the surface wheel-rail existing in the state of the technique.

The bipestana, concave, rounded, convex, and convex wheel technical solution is compatible with the BLOCK DIVERY TO DEVIDE THE MOBILE MATERIAL FROM ONE ROAD TO ANOTHER (<)} , since it is completely feasible to adopt it in the aforementioned diversion, thereby facilitating the passage of the mobile material with a bipestana, concave wheel.

In Block 1 four coupons of the mentioned lane, two pairs each consisting of a straight coupon and another curved.

In the section of greatest approximation between the coupon straight and curved the profile of them would be partially modified, because the skates of both of the common side would be trimmed, although united monolithically.

In Block 2 a single lane would be mounted rounded head, reduced and convex, maintaining that profile only in 1 upper part of the soul, approximately in a forty percent of its total height, while the remaining part of the soul would have a rectangular shape, required by needs for fixing the ROTATING MOBILE PLATE.
