Description

Heart piece composed of Vignole rails While it is the case with grooved rail heart pieces is known, these frogs through the inlay of double cheek grooved wedges or other Vignol rail frogs are used to make inserts made of special steel wear-resistant hitherto generally only made from splints of normal quality.

In order to now put them together from Vignole rails of normal quality Heart pieces at their places that are particularly subject to wear and tear to make wear-resistant and thereby increase the service life of the frogs, it has already been proposed that the actual frogs or frog tips to produce forming parts from cast bodies, which by screwing with the subsequent Rails are connected. The production of such frogs is due to high manufacturing and machining costs of the cast body extremely time consuming and expensive, so that such core pieces in railway operations have so far been none or only found few uses.

Another suggestion comes out, in addition to the castings mentioned also to arrange steel inserts in the wing rails, the steel inserts Support directly on the rail foot and screw it to the rails or riveting. Should such steel inserts be made of wear-resistant, high quality stainless steel, so the manufacturing cost is one Such a focal point is very high, as a result of the inserts that extend to the foot of the rail a large amount of the expensive wear-resistant material is required. In the end it has still been proposed that the wear-resistant one forming the frog tip be Insert hat-shaped onto the two butting parts that form the frog point itself Put on rails. In these designs, however, the insert consists of a relatively large and difficult to machine and therefore expensive cast body, the front part of which reaches directly up to the webs of the wing rails, is supported on the latter and connected to them by screwing or the like is.

The subject of the present invention relates to one made of Vignole rails composite centerpiece, in which the areas subject to wear through particularly simple, easy to manufacture and apply means under the greatest possible Material savings are made wear-resistant. The invention consists in that the inside of the heads of the kinked rails with an insert made of wear-resistant Material, such as manganese steel, are provided, and that from the colliding Rails formed frog point with a these two rails overlapping Hat is made of wear-resistant material. Compared to the known facilities the subject matter of the invention has the advantage that the tread the Inserts made of wear-resistant material only form wing rails are inserted into the rail heads of these rails, so that only small amounts of the expensive 'wear-resistant material are required. There is also an essential one Characteristic of the invention is that the wear-resistant inserts the rail heads to be undercut on the outside and on the inside with the inner edges their approximately horizontal floor surfaces with the rails by welding or rolling o. The like. Are firmly connected. This becomes a solid, avoiding any Connection of even required items, such as screws, rivets or the like., One immovably solid embedding of the inserts in the heads of the bent rails achieved and urmaalicht, with me vain single weld seam to attach the Einlagest; icke attszttlconttttett, m-obei clie.se weld as a result of their depth 1. is not touched by the wheel flanges. Finally, that shows them the frog point formed over the colliding rails compared to the known devices has the advantage that it is without immediate Support on the kinked rails with the lower edges of its, the colliding ones Rails hat-shaped overlapping legs with the rails by welding or Roll-in is firmly connected, so that the required amount of the expensive, wear-resistant material compared to the known facilities significantly reduced is and thereby the manufacturing costs are reduced, especially since the hat-shaped Wedges can be made from rolled bars.

The drawing illustrates an embodiment of the invention.

Fig. A is a section along line 2-a of Fig. I.

Fig. 3 is a section along line 3-3 of Fig. I. The centerpiece tip is formed on one side by the colliding rails d and b, over the hat made of wear-resistant material over the corresponding length c after appropriate elaboration - the rail heads are turned over. The other side of the frog is formed by the kinked rails d and e, which are in the The area of the actual core is provided with the wear-resistant inserts f and g that undercut the rail heads on the outside.

Both the hat c and the deposits f and a have horizontal or approximately horizontal floor support surfaces to ensure a secure support and ensure even pressure transfer. la denotes the welds for attaching the inlet or the I1tttstückcs tttit Bett Sliiett # t @.
