Abstract

The utility model relates to a railway locomotive component, particularly a railway freight car coupler yoke supporting plate component for a railway freight car steering bogie and a wear plate thereof. The railway freight car coupler yoke supporting plate component comprises a base plate and a wear plate. The two sides of the wear plate are bent downwardly to form a U-shaped groove with the width slightly wider than that of the base plate, the wear plate is arranged on the upper surface of the base plate in a spanning way, and two pairs of positioning blocks are welded and fixed at the edges on the two sides of the base plate to block the front end surface and the rear end surface of the wear plate. In the supporting plate component, the wear plate and the base plate are in direct lap joint without welding, so as to reduce variation of the internal stress of the base plate generated during a welding process, thereby improving the breakage resistant capacity of the base plate during operation, reducing the cracking possibility of the base plate, and ensuring travelling safety.

Description

Railway freight car coupler tail frame blade assemblies and wearing plate thereof

Technical field

The utility model belongs to the railway locomotive parts, relates to a kind of railway freight car coupler tail frame blade assemblies and wearing plate thereof that is used on the railway goods train bogie.

Background technology

Traditional railway freight car coupler tail frame blade assemblies is made up of a substrate 11 and a wearing plate 12 that is weldingly fixed on the upper surface of base plate, wearing plate and substrate carry out the large tracts of land welding and have not only increased manufacture difficulty, also can cause baseplate material to produce bigger internal stress, in use rupture easily, influence the safety of vehicle '.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of simple in structure, easily manufactured, railway freight car coupler tail frame blade assemblies that safe reliability is good is provided and is used for the wearing plate of this blade assemblies.

Railway freight car coupler tail frame blade assemblies of the present utility model includes substrate and wearing plate, the dual-side of described wearing plate bends downwards, form the U-lag that a width is slightly larger than substrate width, wearing plate passes through this U-lag across settling on the upper surface of base plate, be welded with two pairs of locating pieces in the both sides of the edge of substrate, locating piece is blocked in the front/rear end place of wearing plate.

In the blade assemblies of the present utility model, wearing plate and substrate directly overlap and need not welding, thereby have reduced the variation of the substrate internal stress of welding process generation, thereby have improved the ability of the anti-destruction when substrate is worked, reduce the possibility of substrate fracture, guaranteed traffic safety.

The specific embodiment

As Fig. 2, shown in Figure 3, railway freight car coupler tail frame blade assemblies of the present utility model comprises substrate 21 and the wearing plate 22 that is placed on the substrate, the cross sectional shape of wearing plate as shown in Figure 4, it has a downward U-lag 23, this U-lag is stuck in the dual-side place of substrate, realize the located lateral of wearing plate, the longitudinal register of wearing plate is realized by two pairs of locating pieces 24 that are welded on the substrate both sides of the edge and be positioned at before and after the wearing plate.

Claims

1, a kind of railway freight car coupler tail frame blade assemblies, include substrate (21) and wearing plate (22), it is characterized in that: the dual-side of described wearing plate bends downwards, form the U-lag (23) that a width is slightly larger than substrate width, wearing plate passes through this U-lag across settling on the upper surface of base plate, be welded with two pairs of locating pieces (24) in the both sides of the edge of substrate, locating piece is blocked in the front/rear end place of wearing plate.

2, a kind of wearing plate of railway freight car coupler tail frame blade assemblies is characterized in that: its plate body both sides of the edge bend downwards, form the U-lag (23) that a width is slightly larger than substrate width
