Abstract
The utility model provides a novel brake shoe with fracture resistance, which comprises a shoe back, braking blocks, a shoe nose, stopping blocks, frames and auxiliary ribs, wherein the braking blocks are welded on the frames, and the frames, the shoe nose, the stopping blocks and the auxiliary ribs are welded on the shoe back. The innovation is that the auxiliary ribs are welded on the lateral side of the shoe back to enhance the strength of the shoe back and the weld strength of the frames, and the adjacent frames are closely connected and welded on the shoe back or all the braking blocks are sintered on the same frame and then welded with the shoe back.
Description
Technical field
The utility model relates to the rail vehicle braking device, particularly relates to a kind of novel brake shoe.
Background technique
Brake shoe is a particularly important braking member in the railroad train braking system of rail vehicle.The railroad train of speed class below 160km/h; thereby using brake shoe that pressing friction is carried out on the wheel-tyre surface usually realizes slowing down and brake operating; face " high-speed overload " demand of visitor, freight train; when train brakes; the impacting force that acts on brake shoe watt back is very big, and brake shoe of the prior art is because watt back of the body insufficient strength fracture occurs through regular meeting.
Summary of the invention
The technical problem that solves
For addressing the above problem, the utility model provides a kind of novel brake shoe, the situation of brake shoe watt back of the body fracture in the time of can effectively solving brake.
Technological scheme
The anti-fracture brake shoe that the utility model provides is made up of watt nose 1, block 2, watt back of the body 3, auxiliary muscle 4, skeleton 5, brake block 6, and brake block 6 sintering are on skeleton 5, and watt nose 1, block 2, auxiliary muscle 4, skeleton 5 are welded on watt back of the body 3.Mode as shown in Figure 1, auxiliary muscle 4 are welded on watt back of the body 3 both sides, can effectively strengthen watt intensity of the back of the body 3.In the train brake process, the train brake system applies brake pressure by watt nose 1 to brake shoe, and the fixation by block 2 prevents that brake shoe from rotating, and makes brake shoe pressing friction wheel-tyre surface.Because two auxiliary muscle 4 is welded on watt both sides of the back of the body 3, stop watt back of the body 3 that elastic strains take place, therefore can effectively prevent watt back of the body 3 since the brake block 6 that elastic strain causes and wheel-tyre surface friction area reduce and watt carry on the back 3 exceed the phenomenon that the elastic strain ability ruptures.
For further strengthening watt anti-deformation intensity of the back of the body 3, the skeleton 5 that the utility model has a brake block 6 with sintering is being welded on watt back of the body 3 of close proximity successively, the support of 4 pairs of watts of back ofs the body 3 of auxiliary in addition muscle, the resistance of novel brake shoe of the present utility model becomes, anti-fracture ability is further strengthened.Be specially: brake block 6 of each skeleton 5 sintering, being welded to watt on the back of the body 3 of close proximity between the adjacent skeleton 5, the skeleton 5 after the welding, auxiliary muscle 4 are born brake pressure jointly with a watt back of the body 3, can ensure that therefore fracture can not appear in watt back of the body 3 when brake.
Also all brake block 6 sintering that can brake shoe is required are on same skeleton 5, there is the skeleton 5 of brake block 6 to carry out bending sintering, bending position does not conflict mutually with the position of brake block 6, make radian after skeleton 5 bendings basic with watt to carry on the back 3 consistent, skeleton 5 after sintering had brake block 6 and carried out bending is welded on watt back of the body 3, soldering point spread all over skeleton 5 around, the support of 4 pairs of watts of back ofs the body 3 of auxiliary in addition muscle, so skeleton 5, auxiliary muscle 4 are born brake pressure jointly with a watt back of the body 3 after the welding, can ensure that therefore fracture can not appear in watt back of the body 3 when brake.
Beneficial effect
Because skeleton 5, auxiliary muscle 4 are taked new welded structure with a watt back of the body 3, the three bears brake pressure jointly, can ensure that therefore fracture can not appear in watt back of the body 3 when brake.

Fig. 3 is a novel brake shoe schematic perspective view of the present utility model.
Embodiment
In conjunction with the accompanying drawings, the anti-fracture brake shoe that the utility model provides is made up of watt nose 1, block 2, watt back of the body 3, auxiliary muscle 4, skeleton 5, brake block 6, and brake block 6 sintering are on skeleton 5, and watt nose 1, block 2, auxiliary muscle 4, skeleton 5 are welded on watt back of the body 3.Mode as shown in Figure 1, auxiliary muscle 4 is welded on watt back of the body 3 one sides or both sides, can effectively strengthen watt intensity of the back of the body 3.In the train brake process, the train brake system applies brake pressure by watt nose 1 to brake shoe, and the fixation by block 2 prevents that brake shoe from rotating, and makes brake shoe pressing friction wheel-tyre surface.Because auxiliary muscle 4 is welded on watt side of the back of the body 3, stop watt back of the body 3 that elastic strains take place, therefore can effectively prevent watt back of the body 3 since the brake block 6 that elastic strain causes and wheel-tyre surface friction area reduce and watt carry on the back 3 exceed the phenomenon that the elastic strain ability ruptures.Described auxiliary muscle 4 can be a side that is welded on watt the back of the body 3, also can be welded on watt both sides of the back of the body 3 for two.
For further strengthening watt anti-deformation intensity of the back of the body 3, the skeleton 5 that the utility model has a brake block 6 with sintering is being welded on watt back of the body 3 of close proximity successively, the support of 4 pairs of watts of back ofs the body 3 of auxiliary in addition muscle, anti-deformation, the anti-fracture ability of novel brake shoe of the present utility model are further strengthened.Be specially: brake block 6 of each skeleton 5 sintering, being welded to watt on the back of the body 3 of close proximity between the adjacent skeleton 5, the skeleton 5 after the welding, auxiliary muscle 4 are born brake pressure jointly with a watt back of the body 3, can ensure that therefore fracture can not appear in watt back of the body 3 when brake.
Also all brake block 6 sintering that can brake shoe is required are on same skeleton 5, there is the skeleton 5 of brake block 6 to carry out bending sintering, bending position does not conflict mutually with the position of brake block 6, make radian after skeleton 5 bendings basic with watt to carry on the back 3 consistent, skeleton 5 after sintering had brake block 6 and carried out bending is welded on watt back of the body 3, soldering point spread all over skeleton 5 around, the support of 4 pairs of watts of back ofs the body 3 of auxiliary in addition muscle, so skeleton 5, auxiliary muscle 4 are born brake pressure jointly with a watt back of the body 3 after the welding, can ensure that therefore fracture can not appear in watt back of the body 3 when brake.
