Shape size and similar structure also cause certain impact to the brake strip spare part storage of both models.
【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of universal brake strip, energy
Enough make brake strip that there is the functional structure of EQ158 types brake strip and the widened brake strip of 457 bridges simultaneously, can be with
Fully substitute the installation of the brake strip of both models, highly versatile reduces mistake and takes and misuses phenomenon, improves installation effect
Rate, facilitates the spare part storage of brake strip.
For achieving the above object, the utility model proposes a kind of universal brake strip, including friction plate body, institute
That states friction plate body is shaped as circular arc bent plate, and the edge of the friction plate body is provided with some positioning fixing holes, described to rub
Some first installing holes are provided with the middle part of pad body, some second installing holes are provided with the middle part of the friction plate body.
Preferably, the friction plate body is shaped as square arc bent plate, the shape size of the friction plate body
Identical with the shape size of EQ158 type brake strips, the quantity of the positioning fixing hole has eight, eight positioning fixing holes point
Two rows along friction plate body the symmetrical marginal position for being distributed in friction plate body of vertical middle separated time, the positioning fixing hole
For counter sunk mounting holes.
Preferably, the quantity of first installing hole has four, four positioning fixing holes are divided to two rows along friction plate body
The symmetrical middle part for being distributed in friction plate body of vertical middle separated time, first installing hole be counter sunk mounting holes, it is described fixed
The position of position fixing hole and the first installing hole corresponds with all position of mounting hole on the widened brake strip of 457 bridges.
Preferably, the quantity of second installing hole has four, four positioning fixing holes are divided to two rows along friction plate body
The symmetrical middle part for being distributed in friction plate body of vertical middle separated time, second installing hole be counter sunk mounting holes, it is described fixed
The position of position fixing hole and the second installing hole corresponds with all position of mounting hole on EQ158 type brake strips.
The beneficial effects of the utility model:The utility model is by the way that friction plate body, positioning fixing hole, first are installed
Hole, the second installing hole are combined together, and through optimum experimental, brake strip can be made to have EQ158 type drag frictions simultaneously
The functional structure of piece and the widened brake strip of 457 bridges, can fully substitute the installation of the brake strip of both models,
Highly versatile, reduces mistake and takes and misuse phenomenon, improves installation effectiveness, facilitates the spare part storage of brake strip.
Feature of the present utility model and advantage will combine accompanying drawing and be described in detail by embodiment.

【Specific embodiment】
Refering to Fig. 1, Fig. 2 and Fig. 3, a kind of universal brake strip of the utility model, including friction plate body 1, it is described
Friction plate body 1 is shaped as circular arc bent plate, and the edge of the friction plate body 1 is provided with some positioning fixing holes 2, described to rub
The middle part of pad body 1 is provided with some first installing holes 3, and the middle part of the friction plate body 1 is provided with some second and installs
Hole 4, the friction plate body 1 is shaped as square arc bent plate, shape size and the EQ158 type systems of the friction plate body 1
The shape size of movable friction plate is identical, and the quantity of the positioning fixing hole 2 has eight, and eight positioning fixing holes, 2 point of two rows edge is rubbed
The symmetrical marginal position for being distributed in friction plate body 1 of vertical middle separated time of pad body 1, the positioning fixing hole 2 is heavy
Head installing hole, the quantity of first installing hole 3 has four, and four positioning 2 point of two rows of fixing hole are along the vertical of friction plate body 1
The symmetrical middle part for being distributed in friction plate body 1 of middle separated time, first installing hole 3 is counter sunk mounting holes, and the positioning is consolidated
The position and all position of mounting hole on the widened brake strip of 457 bridges for determining the installing hole 3 of hole 2 and first corresponds, institute
Stating the quantity of the second installing hole 4 has four, vertical middle separated time or so of four positioning 2 point of two rows of fixing hole along friction plate body 1
It is symmetrically distributed in the middle part of friction plate body 1, second installing hole 4 is counter sunk mounting holes, the positioning fixing hole 2 and second
The position of installing hole 4 corresponds with all position of mounting hole on EQ158 type brake strips.
Utility model works process:
The utility model is by the way that friction plate body 1, positioning fixing hole 2, the first installing hole 3, the second installing hole 4 are combined
Together, through optimum experimental, can make brake strip that there is EQ158 types brake strip and the widened braking of 457 bridges simultaneously
The functional structure of friction plate, can fully substitute the installation of the brake strip of both models, and highly versatile reduces mistake and takes
Phenomenon is misused, installation effectiveness is improved, the spare part storage of brake strip is facilitated.
Above-described embodiment be to explanation of the present utility model, be not to restriction of the present utility model, it is any new to this practicality
Scheme after type simple transformation belongs to protection domain of the present utility model.
