Definitions
- the invention relates to a stock rail for the
- Rail head a rail web and a rail foot, wherein the stock rail has a first longitudinal section forming an abutment area for a tongue rail and a second one lying outside the abutment area
- the stock rail has a cross-sectional basic profile in the second longitudinal section, which has a central axis running through the center of the rail head cross-section, the rail head being machined in the first longitudinal section starting from the cross-sectional basic profile, comprising a chamfer that starts from a driving edge in the direction Rail web runs inclined, the driving edge at the point of
- Rail head cross-section is formed with the largest normal distance to the central axis, and comprising a running width reduction of the rail head, so that the
- the central axis of the stock rail lies, the rail head having essentially no width reduction at least at a first location within the first longitudinal section and a maximum width reduction at least at a second location within the first longitudinal section.
- the invention further relates to a rail switch
- tongue rails Susceptibility to wear. It has therefore been proposed several times to manufacture tongue rails from special, wear-resistant materials or to harden them by subsequent treatment.
- head-hardened tongue rails are generally not used for safety reasons because any signs of wear on the tongue rail should be visible, so that a risk of breakage can be recognized prematurely.
- head-hardened tongue splints however, a fracture usually occurs as a brittle fracture, so that one
- tongue rails were therefore proposed several times, which are made thicker in order to be able to safely absorb transverse forces.
- the tongue ends towards the cheek rails are known, the tongue ends towards the cheek rails
- the tongue rail engages in the Cutouts in the stock rail so that there is a continuous running edge in the transition area from
- the stock rails are filled with adjusting wedges.
- the stock rail engages in a recess in the stock rail is also known from US-A-175,699.
- EP 040533 A2 it has also become known in an area in which the tongue rail lies against the stock rail to reduce the width of the back rail in the head and foot area in such a way that the tongue can be designed in this transition area in accordance with the rail head profile.
- the profile of the stock rail is greatly weakened, so that there is an increased risk of breakage.
- the rail head profile is often used
- the stock rail is milled downwards in the area of the tongue system, as is known, for example, from DE PS 487877.
- Original driving edge course is influenced as little as possible in order to increase the comfort when driving on the switch.
- Cheek rail head by chamfering in the upper area of the stock rail head there is a risk of burr formation because the angle between the chamfer and the adjacent surface of the stock rail head increases with material removal, i.e. as the width of the stock rail head decreases, becomes more pointed.
- Impeller in the area of the ridge with the cheek pads in lateral contact because the stock rail has its largest head width here. Because of this burden the risk of breakouts in the area of the ridge, which causes wear of the stock rails compared to one
- the driving edge at the first point and the driving edge at the second point essentially lie in a common driving edge plane which is arranged at right angles to the central axis.

- Width reduction are essentially designed as at the first, designed without width reduction, at which the chamfer from the driving edge of the
- the invention enables a design in which the width reduction of the stock rail head essentially takes place by horizontal displacement of the chamfered stock rail base profile.
- the intersection of the chamfer with the adjacent curved surface area of the rail head with increasing width reduction, other than in the prior art, does not result in an increase in the running edge combined with an increasingly acute intersection angle, but rather the geometrical relationships over the length can be designed to be constant.
- the cross-sectional basic profile preferably corresponds to a Vignol rail.
- Cross-section has a curved surface section extending upward from the driving edge and between the chamfer and that through the driving edge
- an angle is formed, which is at least at the first and at the second point, preferably along the entire first longitudinal section, 0-20 ° greater than the angle between the chamfer and the central axis, said angle preferably at the first and the second position, preferably along the entire first
- the rail head is vertically above the first longitudinal section
- Cross section arranged in the vehicle edge plane has an area whose shape essentially corresponds to the corresponding shape of the basic profile.
- this area adjoins the driving edge. Above this range, for example, a curvature with a smaller one
- Radius can be provided to provide a transition to the cross-sectional basic profile.
- the normal distance between the center axis and the rail head edge continuously decreases above the plane of the running edge. This is possible, for example, with a curved course. There are therefore no areas above the driving edge in which the normal distance between the central axis and the rail head edge.
- the chamfer has an incline of 1: 2.5-1: 3.5, in particular 1: 3. This creates a taper vertically downwards, which enables the tongue rail to rest securely on the stock rail. It is preferably provided that the driving edge at the second point within the first longitudinal section is 5-15 mm, preferably 6-10 mm closer to the central axis than the first point, so that a corresponding one
- Reinforcement of the tongue rail can be done. As a result, a sufficient width reinforcement of the tongue rail is achieved without the traveling edge of the stock rail being displaced excessively when the tongues are lying down.
- the running edge of the rail is at the widest point on the rail head, which is at a predefined or standard distance from the vertical
- Driving edge is measured. It is preferably provided that the driving edge plane in one in the first longitudinal section
- the normal distance of the driving edge from the central axis decreases continuously from the first point to the second point and increases again, preferably continuously, in the area adjoining the second point. This creates the possibility, in particular, of the degree of reinforcement
- Tongue rail to adjust the shear force course along the rail.
- Digit decreases to the second digit in an arc and on the area adjoining the second point again, preferably in an arc shape, increases.
- a rail switch comprising a stock rail according to the invention and a tongue rail, the tongue rail being arranged such that it can be placed on the stock rail.
- the tongue rail is made reinforced in cross-section toward the stock rail in accordance with the reduction in the width of the stock rail head.
- Tongue rail up to a point within the
- the tongue rail is thus strengthened in the sensitive transition area of the load from the stock rail to the tongue rail and this increases the cross-section and thus increases the moment of inertia
- Tongue rail reached so that the tongue rail the
- a jerky track change is avoided by the preferably constant change in cross-section, so that the Driving comfort not negatively affected and one
- a particularly resilient and wear-resistant switch results when the greatest reinforcement of the tongue rail is formed in the area in which the impeller comes into lateral contact with the tongue rail and it is therefore the switch according to the invention according to one
- preferred training further developed such that the point with the greatest reinforcement of the tongue rail or with the smallest width of the stock rail head at a distance of 1/6 to 1/3, preferably 1/4, the length of the contact of the tongue rails to the stock rail from the Tip of the tongue lies.
- the point of greatest reinforcement of the tongue rail is near the tip of the tongue, and in this connection the design is such that the point with the largest
- Width of the stock rail head lies at a distance of 1/20 to 1/10 of the length of the contact between the tongue rail and the stock rail from the tip of the tongue.
- the switch is advantageously developed in such a way that the vertical height of the tongue rail in the area of the system to the stock rail starting from the tip of the tongue in
