Abstract
A rail car truck has a pair of longitudinally spaced wheelsets and a pair of laterally spaced side frames which extend between and are supported by the wheelsets. A bolster extends between the side frames to support the rail car vehicle body. There is a brace which is connected to the side frames to control relative longitudinal movement therebetween. The brace includes a pair of struts which are diagonally connected to the side frames on opposite sides of the centerline thereof. The struts intersect generally centrally of the side frames and there is a clamp assembly for attaching the struts together. The clamp assembly includes a pair of clamp plates, each having a channel formed and adapted to receive a strut.

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.
Every clamping plate 32 and 34 all have the parallelogram configuration that has side 54, the long axis that these sides make clamping plate have and depression is parallel, and the minor axis vertical with depression.Clamping plate are tightened together by means of fastener 56, and these fasteners extend to such an extent that pass the hole 57 of aliging in the clamping plate, so that provide as Figure 10 and cleat assembly shown in Figure 11.
In use, cleat assembly provides fastening, powerful interconnection between each intersection slash or the arm support.Every slash is welded on the clamping plate, and after the clamping plate combination, they just are connected together by the edge joint weld along adjacency.Adopt U-shaped otch and very important along the weld nugget of these otch.By determine weld nugget on the U-shaped otch of each clamping plate depression end, weld nugget has just been moved to the zone of low unrelieved stress by the zone from high residual stress.In this respect, should be noted that those U-shaped weld nuggets between clamping plate and the slash, is that this surface is the low unrelieved stress zone of slash along the generally planar or slight curving surface 40 of slash.In addition, the relatively more close neutral axis that imposes on the side-bend load of cleat assembly in the position of U-shaped weld nugget.Will reduce the stress in each weld nugget like this, prolong the available life of cleat assembly thus again.
Though shown and recommendation form of the present invention be described, should understand, can do many modifications, substitute and conversion repeatedly it.
