Abstract
The utility model provides an anti-breaking brake shoe, which consists of a back, a brake block, a nose block, stoppers and a framework, wherein the brake block is sintered on the framework, and the framework, the nose block and the stoppers are welded on the back. The anti-breaking brake shoe is characterized in that the framework is welded via a novel method including closely welding adjacent frameworks onto the back or all the brake blocks are sintered on the same framework which is further welded with the back.
Description
Technical field
The utility model relates to the rail vehicle braking device, particularly relates to a kind of anti-fracture 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 wheel-tyre is carried out pressing friction 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 anti-fracture 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 a watt back of the body 1, brake block 2, watt nose 3, block 4, skeleton 5, and brake block 2 sintering are on skeleton 5, and skeleton 5, watt nose 3, block 4 are welded on watt back of the body 1.
As shown in Figure 1, for solving the situation of brake shoe watt back of the body fracture when braking, the utility model has the skeleton 5 of brake block 2 closely to be welded to successively on watt back of the body 1 sintering.Brake block 2 of each skeleton 5 sintering leaves certain distance between each skeleton of the brake shoe of prior art, therefore causes watt back of the body strength not as close proximity structure of the present utility model.In the utility model,,, can ensure that therefore fracture can not appear in watt back of the body 1 when brake so skeleton 5 is born brake pressure jointly with a watt back of the body 1 after the welding because distance levels off to zero distance between the adjacent skeleton 5.
As Fig. 2, Fig. 3 and shown in Figure 4, for solving the situation of brake shoe watt back of the body fracture when braking, the utility model provides another solution, be about to all required brake block 2 sintering of brake shoe on same skeleton 5, there is the skeleton 5 of brake block 2 to carry out bending sintering, bending position does not overlap with the position of brake block 2, make radian after skeleton 5 bendings basic with watt to carry on the back 1 consistent, skeleton 5 after sintering had brake block 2 and carried out bending is welded on a watt back, soldering point spread all over skeleton 5 around, so skeleton 5 is born brake pressure jointly with a watt back of the body 1 after the welding, can ensure that therefore fracture can not appear in watt back of the body 1 when brake.
Beneficial effect
Because skeleton 5 is taked new welded structure with a watt back of the body 1, the two bears brake pressure jointly, can ensure that therefore fracture can not appear in watt back of the body 1 when brake.
Description of drawings
Fig. 1 is that the anti-fracture brake shoe skeleton of the utility model separates sintering, welded structure sectional drawing.
Fig. 2 is integral sintered, the welded structure sectional drawing of the anti-fracture brake shoe skeleton of the utility model.
Fig. 3 is the integral sintered section of structure of the anti-fracture brake shoe skeleton of the utility model.
Fig. 4 is the integral sintered structural bending sectional drawing of the anti-fracture brake shoe skeleton of the utility model.
Embodiment
The anti-fracture brake shoe that the utility model provides is made up of a watt back of the body 1, brake block 2, watt nose 3, block 4, skeleton 5, and brake block 2 sintering are on skeleton 5, and skeleton 5, watt nose 3, block 4 are welded on watt back of the body 1.Act as and watt nose 3 of described block 4 prevents that jointly brake shoe departs from hub body when brake.
As shown in Figure 1, for solving the situation of brake shoe watt back of the body fracture when braking, the utility model has the skeleton 5 of brake block 2 closely to be welded to successively on watt back of the body 1 sintering.Brake block 2 of each skeleton 5 sintering leaves certain distance between each skeleton of the brake shoe of prior art, therefore causes watt back of the body strength not as close proximity structure of the present utility model.In the utility model,,, can ensure that therefore fracture can not appear in watt back of the body 1 when brake so skeleton 5 is born brake pressure jointly with a watt back of the body 1 after the welding because distance levels off to zero distance between the adjacent skeleton.
As Fig. 2, Fig. 3 and shown in Figure 4, for solving the situation of brake shoe watt back of the body fracture when braking, the utility model provides another solution, be about to all required brake block 2 sintering of brake shoe on same skeleton 5, there is the skeleton 5 of brake block 2 to carry out bending sintering, the position that bending position is refused brake block 2 overlaps, make radian after skeleton 5 bendings basic with watt to carry on the back 1 consistent, skeleton 5 after sintering had brake block 2 and carried out bending is welded on a watt back, so skeleton 5 is born brake pressure jointly with a watt back of the body 1 after the welding, can ensure that therefore fracture can not appear in watt back of the body 1 when brake.
