Abstract
The utility model discloses a light-rail vehicle bogie brake base. In order to simplify the mounting structure of a brake and improve the connecting strength of the brake, and the bogie brake base comprises a brake base body; a hanging anti-falling hole is formed in the upper portion of the brake base body, and a plurality of mounting holes used for mounting the brake are formed in the brake base body; the lower portion of the brake base body is provided with a plurality of connecting plates used for connecting vertical plates of a cross beam. Due to the light-rail vehicle bogie brake base, a frame of the bogie with the cross beam of a box-type structure is not provided with an end beam any more, and the light-rail vehicle bogie brake base is simple in structure, safe and reliable.
Description
Technical field
The utility model relates to design, the manufacture field of light rail car bogie truck brake seat, is specially a kind of light rail car bogie truck brake seat.
Background technology
Urban rail car bogie brake seat is the critical component of truck frame, and its structure directly has influence on traffic safety.Light rail car is less by radius of curve, therefore, light rail car is generally provided with bolster structure, this has just limited the design space of brake seat, make comparatively difficulty of box crossbeam brake seat design, often, by setting up end carriage, brake seat is arranged on end carriage and is realized, this structure is more complicated, and Joint strenght is not high.
Utility model content
In order to overcome existing crossbeam brake seat, need to be connected on end carriage, structure is more complicated, the deficiency that Joint strenght is not high, the utility model aims to provide a kind of light rail car bogie truck brake seat, it is that the truck frame of box-structure no longer arranges end carriage that this brake seat can make crossbeam, and simple in structure, safe and reliable.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of light rail car bogie truck brake seat, comprises brake seat body; Its constructional feature is that described brake seat body top has lifting anticreep hole, has the multiple mounting holes for drg is installed on this brake seat body; Described brake seat body bottom has the connecting panel of polylith for connecting cross beam riser.
Be below the technical scheme of further improvement of the utility model:
In order to increase installation strength, be convenient to the exchange of hold-down bolt simultaneously, in described mounting hole, the surrounding of part mounting hole has upwardly extending boss, and remaining part mounting hole is upwardly extending cylindrical boss hole.
In order to guarantee to be connected reliably with crossbeam riser, described connecting panel is two, and two connecting panels are all connected with the butt welding of crossbeam riser.Described brake seat body and the integrated casting of connecting panel form.
Further, the mounting hole below of described brake seat body has transition arcs, and whole brake seat body is L-shaped.
By said structure, the drg that this brake seat is installed adopts the mode of top hanging to install, end position design when its oad rotates according to drg oad and bolster; Drg side is installed to be set to boss structure by two sections compared with great circle arc transition and top and to make this brake seat intensity better; Adopt four butt welds to make brake seat welding process better with being connected of crossbeam riser, guaranteed the welding quality of crucial weld seam; On brake seat, be provided with drg slip-off preventing hole, during production, also can do lifting.
Compared with prior art, the beneficial effects of the utility model are: brake seat of the present utility model adopts four butt welds to dock with crossbeam riser, has guaranteed brake seat welding quality; This brake seat adopts boss structure at drg by two inner mounting hole tops, has improved brake seat intensity; This brake seat adopts cylindrical boss on two outer mounting hole tops of drg, has guaranteed the interchangeability of drg hold-down bolt; On brake seat, be provided with drg slip-off preventing hole.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
Accompanying drawing explanation
Fig. 1 is the mounting structure schematic diagram of a kind of embodiment of the utility model;
Fig. 2 is the structural representation of a kind of embodiment of the utility model.
In the drawings
1-crossbeam riser; 2-butt weld; 3 brake seat bodies; 4-boss; 5-cylindrical boss hole; 6 mounting holes; 7-transition arcs; 8-lifts anticreep hole; 9-connecting panel.
The specific embodiment
A kind of light rail car bogie truck brake seat, as shown in Figure 1, according to drg installation requirements, is provided with drg mounting hole 6 on the top of mounting seat of brake body 3 as shown in Figure 2; At the top of mounting seat of brake body 3, be provided with boss 5 and cylindrical boss hole 4; In installation drg side, there are two sections of transition arcs 7 that radius is larger; Connecting panel 9 and the crossbeam riser 1 of mounting seat of brake body 3 bottoms adopt butt weld 2; The top of mounting seat of brake body 3 arranges drg slip-off preventing and produces lifting anticreep hole 8.
The content that above-described embodiment is illustrated should be understood to these embodiment only for being illustrated more clearly in the utility model, and be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
