Problems solved by technology

[0006] However, it has been found in practice that cracks occur in the area where the angular track nails bear against the backing plate, and despite the high strength and wear resistance of the steel material used to manufacture the known backing plate, these cracks will cause the backing plate to quickly collapse. can not be used

Embodiment Construction

[0030] In a plan view, the backing plate 1 formed entirely by plastic, such as DIN abbreviated as PA6GF30 (30% glass fiber content) glass fiber reinforced polyamide plastic, has a rectangular, elongated basic shape: Long sides 2 , 3 running parallel to one another in longitudinal direction LU and two narrow sides 4 , 5 , also parallel to one another and transverse to long sides 2 , 3 , extend over width BU of backing plate 1 .

[0031] The backing plate 1 has a flat support surface 6 on the underside U, which rests in the mounting position with the support surface (attached Figure 4 ) stands on the flat support surface 8 arranged on the upper side of the crossties 7 .

[0032] Adjacent to the narrow side 4 , a first support section 9 is formed on the backing plate 1 , which has the full width BU of the backing plate 1 and a first partial length TL1 . On the upper side O opposite the lower side U of the base plate 1 , the support section 9 rises continuously like a roof surfa...

Abstract

A base plate includes a lateral support section and a lateral contact surface which delimits a supporting area formed on a top side of the base plate for a foot of a rail. A through-hole leading from the top side to the underside of the support section is formed into an edge area of the support section abutting the lateral contact surface. The through-hole has a basic shape which is angular in cross-section. The surface of the edge area meets with the contact surface in an upper marginal edge. A lateral surface of the through-hole assigned to the contact surface at least over a partial area of its height changes into an inclined surface which rises in the direction of the upper marginal edge of the contact surface and ends at the surface of the edge area.

Description

technical field [0001] The invention relates to a backing plate for a rail fastening point, the backing plate having at least one transverse support section with a transverse contact surface delimited by a rail base of a rail of a rail vehicle to be placed on the backing plate A footprint formed on the upper side of the base plate and extending over the width of the base plate. In order to insert spikes in the edge region of the support section adjoining the transverse bearing surface, a through-opening is formed extending from the upper side to the underside of the support section, which, viewed in a cross section transverse to its longitudinal axis, has The basic shape of an angle. The surface of the edge region thus intersects the upper boundary edge of the contact surface, which extends over the width of the backing plate. Background technique [0002] Such backing plates are used in particular in rail fastening points arranged on sleepers. On the one hand, the backin...
