The brake shoe has transverse through cracks and large-area block falling, and the use requirement of the product cannot be met. Therefore, a reinforced brake shoe back is needed to ensure that the brake shoe can meet the use requirements.
Disclosure of Invention
The utility model aims at providing a synthetic brake shoe strenghthened type tile back of body for railway locomotive has solved that traditional arc synthetic brake shoe tile back of body constructional strength is low, warp easily, causes the problem that the friction body drops with the separation of tile back of body. The friction plate is not easy to bend and deform, is convenient to press and process, and can be firmly combined with a friction body.
The utility model adopts the technical proposal that: the utility model provides a composite brake shoe strenghthened type tile back of body for railway locomotive, is provided with the nose of tile in the middle of the tile back of body including the tile back of body that has arc bending surface, tile back of body length direction tip symmetry is provided with the locating piece, and its technical essential is: rectangular block-shaped reinforcing ribs protruding outwards are symmetrically arranged in the length direction of the tile back body; a strip-shaped material grabbing hole is formed between the edge of the tile back body in the width direction and the reinforcing rib, and a reverse splayed material grabbing plate is arranged along the opening in the length direction of the material grabbing hole; the positioning blocks are vertical wing plates which are transversely symmetrically turned outwards on the tile back body.
The tile back body part at the bottom of the tile nose is provided with a sunken groove.
The longitudinal section of the reinforcing rib is in a trapezoid shape, the width of the top of the trapezoid shape is smaller than that of the opening at the bottom of the trapezoid shape.
The hole of grabbing of tile nose both sides is eight groups, and the equipartition sets up the both sides at two strengthening ribs of tile nose.
The utility model has the advantages and positive effects that: because this composite brake shoe strenghthened type tile back for railway locomotive is provided with outside bellied rectangular block form strengthening rib at the length direction of tile back body, consequently it outwards forms the bellying at the tile back body, inwards forms the depressed part, has all formed vertical lateral wall at width direction and length direction, plays the enhancement supporting role to tile back body width direction and length direction, can suppress into the friction piece at the depressed part simultaneously, has increased the intensity that combines with the friction piece. The material grabbing holes and the reverse splayed material grabbing plates are arranged on the outer sides of the reinforcing ribs, so that the bonding strength of the friction body is improved; the reinforcing ribs, the material grabbing holes and the symmetrically-outward-turned vertical wing plate type positioning blocks are adopted, so that the tile back is easily manufactured by directly pressing the whole steel plate, the rapid manufacturing of the tile back is facilitated, and the influence of welding on the structural strength of the back plate is reduced. Therefore, the brake pad is not easy to bend and deform, is convenient to press and process, can be stably and firmly combined with a friction body, has the characteristics of high strength and low cost, does not fracture or fall blocks when put into trial use and operated for six months, and meets the higher use requirement of a brake system.

Detailed Description
According to the specific structure of the present invention as shown in fig. 1-7, the embodiment of the present invention is shown in fig. 1 and 2, a reinforced composite brake shoe back for railway locomotive, wherein the back body 1 can be made of a steel plate of Q235B with a thickness of 5mm by pressing, and the middle of the back body is provided with a shoe nose 3. Tile back of body 1 uses tile nose 3 as the center of symmetry, it has outside bellied rectangular block shape strengthening rib 2 to suppress at length side symmetry, the apex angle and the side edge portion of strengthening rib adopt circular arc transition face, as shown in fig. 4, the strengthening rib outwards forms the bellying at tile back of body, inwards form depressed part 22, longitudinal side wall 21 has all been formed at width direction and length direction, play the strengthening support effect simultaneously to tile back of body width direction and length direction, the frictional body can be filled to the depressed part, increase the stability of combining. A strip-shaped material grabbing hole 6 is formed between the edge of the tile back body 1 in the width direction and the reinforcing ribs, as shown in fig. 6, a reverse splayed material grabbing plate 5 is arranged along the edge of the material grabbing hole 6 in the length direction, and the material grabbing plate is formed by pressing the tile back body and used for being inserted into a friction body to increase the combination tightness. The positioning blocks 4 are symmetrically arranged at the end parts of the tile back body in the length direction, and as shown in fig. 5, the positioning blocks 4 are vertical wing plates which are pressed on the tile back body and are transversely symmetrically turned outwards and used for installing and positioning the tile back body.
As a further improvement, as shown in fig. 3, a sunken groove 7 is provided at a portion of the tile back body corresponding to the bottom of the tile nose 3, and a side wall of the sunken groove 7 can function as a reinforcing rib, so that the supporting strength of the tile back body is increased.
As a further improvement, as shown in figure 4, the longitudinal cross-sectional shape of the bar 2 is trapezoidal with the top width being less than the width of the bottom opening, so that the side walls 21 of the bar are formed into a ramp shape which is easy to press work and which increases the support strength.
As further improvement, as shown in figure 2, the material grabbing holes 6 on the two sides of the tile nose 3 are eight groups, and are uniformly distributed on the two sides of the two reinforcing ribs 2 of the tile nose, so that the tightness of the combination of the tile nose and a friction body can be increased, and the influence on the strength of the tile back body is reduced.
The theory of operation, as shown in fig. 7, this composite brake shoe strenghthened type tile back for railway locomotive is when combining with the friction piece hot pressing, the strengthening rib 2 of tile back body 1, grab the material hole and grab flitch 5 and form a plurality of concave-convex surfaces and increased the bonding strength with friction piece 8, the strengthening rib has improved support strength in length and width direction, it is not easy bending deformation, convenient press working, can stably combine with the friction piece, reduce the influence of welding to backplate structural strength, replace original locating piece welded structure at backplate both sides press forming location structure, the cost is saved, and the manufacturing work efficiency is improved.
In conclusion, the purpose of the utility model is realized.
