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

The invention relates to a tie plate for a rail fastening point (B), which tie plate has a lateral supporting section (9, 19), which has a lateral contact face (14, 24), which bounds a standing face (15) formed on the top side (O) of the tie plate (1) for the foot (SF) of a rail (S) to be placed onto the tie plate (1), wherein a passage opening (28-31) leading from the top side (O) to the bottom side (U) of the supporting section (9, 19) is formed in a border region (10, 20) of the supporting section (9, 19) adjacent to the lateral contact face (14, 24), which passage opening has a basic shape that is angular in cross-section, and wherein the surface (11, 21) of the border region (10, 20) meets the contact face (14, 24) at an upper border edge (13, 23). The lateral face (32) of the passage opening (28-31) associated with the contact face (14, 24) changes into an inclined face (36) at least over a partial range of the height (H) of the lateral face, which inclined face rises in the direction of the upper border edge (13, 23) of the contact face (14, 24) and ends at the surface (11, 21) of the border region (10, 20).

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...
