Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on embodiment of the present utility model, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection domain of the present utility model.
Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail, be illustrated in figure 1 the utility model be provided for the brake shoe steel backing plan view of urban track traffic, Fig. 2 is plan view, in conjunction with Fig. 1 and 2, described brake shoe steel backing comprises material grasping hole 1, watt nose 2, positioning element 3, wrong-mounting prevention protruding 4 and welding steel 5, wherein:
The shape in described material grasping hole 1 is circular or rectangle, and the part is combined with friction piece makes straight outer or barb-shaped, after steel backing is compressing with friction piece, and material grasping hole embeds friction piece interior increase adhesive strength, can be applicable to the steel backing of various sizes;
In the orientation type and profile design of described positioning element 3, according to use in frictional force difference and watt holder design with the use of one or more locate shape, described location shape 3 can be perpendicular rack-shaped, contrate bar shaped, boss shape, be applicable to brake shoe locate with a watt installation of holding in the palm, can ensure that brake shoe assembling coordinates, the ability to bear of boss location is larger.
Further, described watt of nose 2 profile design is " M " shape, effectively can ensure the location fit between brake shoe drill and steel backing, effectively alleviates the stressed of corner place, brake shoe rock hole;
Described welding steel 5, for being welded on the liner plate of described watt nose 2 both sides, can effectively increasing brake shoe friction area, reduce the heat load of brake shoe in braking process;
Described wrong-mounting prevention protruding 4 is round platform, can effectively prevent the brake shoe of different model in using process from filling useless by mistake.
In addition, in specific implementation, for increasing the adhesive strength between brake shoe steel backing and friction piece, also can weld stiffening rib 6 in the both sides of described brake shoe steel backing.
