US Patent discloses a kind of railway truck No. 4570544, and it has a pair of side vehicle frame to be supported on the wheel set that longitudinal interval is arranged of some routines.In order to improve the stability of lorry, between side vehicle frame, extending the slash that intersects, to increase the tolerance that vertically moves relatively for side vehicle frame.Between wheel set and side vehicle frame, be equipped with elastic component, to reduce the anti-inclined to one side rigidity of wheel set.Its result just can select the anti-inclined to one side rigidity and the lateral rigidity of lorry, so that best lorry stability to be provided.

The improvement project that US Patent discloses No. 4570544 disclosed the sort of lorries of patent for No. 5243920 specifically, is to have done improvement for the intersection slash is fixed on the anchor clamps zone that is generally midway location between the side vehicle frame together.No. 5584250 patents are the improvement projects that the cleat assembly of No. 5243920 patents is done, and it has strengthened the connection between each root intersection slash, and has cancelled the elastic component in the patent No. 5243920.The present invention is then further improved cleat assembly, promptly by to the reorientating of the weld nugget between every clamping plate and the slash, improves the strength at repeated alternation of each weld nugget, and reduces the stress in each weld nugget.The cleat assembly that provides like this is what strengthened, and has the service life that has increased basically.

In the accompanying drawings, conventional side vehicle frame is denoted as 10, and they are installed in and are denoted as on 12 and 14 the wheel set.Conventional needle bearing is installed on the wheel set, and side vehicle frame is then connected by body bolster 16.This body bolster is bearing on the side vehicle frame by spring 17 as routine.

The slash 18 that intersects is connected between side vehicle frame diagonally with 20, so that provide for the tolerance that meets the requirements that vertically moves relatively between the side vehicle frame.Intersect each ends of

slash

18 and 20, connecting side vehicle frame by means of erection support 22, this bearing is being connected side vehicle frame by base plate 24.A terminal interlock assembly 26 is connecting bearing 22, and this assembly has an outshot that does not show to extend in bearing, and is supporting each root intersection slash 18 and 20.Therefore terminal locking member and erection support comprise an elastic component, so that anti-inclined to one side rigidity and lateral rigidity are provided.

Cleat assembly all is denoted as 30, and all shows in detail in Fig. 3 to 11.Cleat assembly comprises a train wheel bridge 32 and a lower plate 34, and this two clamping plates shape is the same.Every clamping plate include one usually in the depression 36 of central authorities, and slash 18 and one of 20 middle body 38 are positioned at this depression.

The middle body 38 of the every slash that shows with cutaway view more specially as Fig. 9 and Figure 11, comprise a part that can be described as upper surface 40, though this part is slight curving, come relatively flat load compared with lower surface 42, the out-of-shape of lower surface and have an inflexed middle section 44.
