Abstract

The utility model discloses a board neck that backplate that anti deformability is high includes the backplate body, extended by backplate body one end, locating the fixed orifices on the board neck and being located the location portion of the backplate body other end, the middle part is equipped with the strengthening rib that is located under the fixed orifices on the board neck, and the strengthening rib is perpendicular to board neck plane stamping forming's arch, and the bellied height of strengthening rib is the 13 -12 of board neck depth degree, this backplate can be under the prerequisite that does not increase this its amount of metal, has set up the arch that can strengthen backplate carrying capacity in backplate atress great board neck department, protrudingly has a style of one's own with the backplate, through stamping die one shot forming, helps strengthening the rigidity of how much faces on the object and the characteristic of intensity, has overcome the backplate because board neck bending deformation or the phenomenon of rupture that leads to the fact is too concentrated to the atress when the brake.

Description

The backboard that a kind of non-deformability is high

Technical field

The utility model relates to bicycle brake pad technical field, particularly relates to the backboard that a kind of non-deformability is high.

Background technique

Lining is the breaking piece of most critical in bicycle brake system, the quality of braking effect is played a decisive role, the working principle of brake mainly carrys out self-friction, utilize the friction on lining and brake disc (drum) and tire and ground, the kinetic energy of being advanced by vehicle converts the heat energy after friction to, compels to stop bicycle.

Backboard is for vitals that is fixing and support brake pad on lining, backboard is used for fixed friction block, it is connected with vehicle frame by the fixed hole of plate neck, produce shearing force when brake pad and brake disc (drum) contact friction, plate neck is the position that backboard is subject to force intensity maximum, after Long-Time Service, easily deform or crack, increase the parallelism error of brake pad and brake disc (drum), cause friction area to reduce, braking effect is poor.

Model utility content

Technical problem to be solved in the utility model overcomes problems of the prior art, provides the backboard that a kind of anti-plate neck deformability is strong, improve brake pad functional reliability.

The backboard that a kind of non-deformability of the present utility model is high is realized by following technological scheme:

It comprises backboard body, the plate neck extended by backboard body one end, the positioning part being located at the fixed hole on plate neck and being positioned at the backboard body the other end, on plate neck, middle part is provided with the stiffening rib be positioned at immediately below fixed hole, stiffening rib is that the height of stiffening rib projection is the 1/3-1/2 of plate neck depth degree perpendicular to plate neck flat die shaping projection.

Further, the free end of plate neck is provided with radiating structure.

Further, stiffening rib is bar shaped, corrugated, circular, oval, horse shoe shaped or other erose projections.

Further, plate neck is provided with 1 or 1 with the stiffening rib of projection, and stiffening rib is for be arrangeding in parallel or being crisscross arranged.

Compared with prior art, backboard of the present utility model can under the prerequisite not increasing this its amount of metal, at backboard, stressed larger plate neck place is provided with the projection that can strengthen backboard ability to bear, protruding and backboard has a style of one's own, by press tool once-through, contribute to the rigidity of augmented geometric surface and the characteristic of intensity, overcome backboard and too concentrate due to stressed the bending deflection of plate neck or phenomenon of rupture that cause when braking.

Accompanying drawing explanation

In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Embodiment

In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing and most preferred embodiment, the utility model is described in further detail.

The backboard that a kind of non-deformability of the present utility model is high comprises backboard body 4, the plate neck 2 extended by backboard body one end, is located at the fixed hole 3 on plate neck and is positioned at the positioning part 5 of the backboard body the other end, on plate neck, middle part is provided with the stiffening rib 21 be positioned at immediately below fixed hole, stiffening rib is perpendicular to the shaping projection of plate neck flat die, in order to prevent producing incipient crack during punching press, reduce backboard working life, the height of stiffening rib projection is the 1/3-1/2 of plate neck depth degree;

Under the prerequisite of amount of metal not increasing backboard, at backboard, stressed larger plate neck place is provided with the projection that can strengthen backboard ability to bear, protruding and backboard has a style of one's own, by press tool once-through, effectively extend the working life of backboard, structure is simple, is easy to produce applicable commercialization and promotes.

This stiffening rib can be bar shaped, corrugated, circular, oval, horse shoe shaped or other erose projections, plate neck is provided with 1 or 1 with the stiffening rib of projection, multiple stiffening rib can be parallel array and arranges, also can be asymmetric formula to be interspersed, protruding concave surface, convex surface can be arranged on arbitrarily front or the back side of backboard, by changing the surface configuration of backboard plate neck, be that solid matter lineal layout changes into crystal grain solid matter curve distribution by the metallurgical structure of backboard by original crystal grain, contribute to the rigidity of augmented geometric surface and the characteristic of intensity, overcome backboard and too concentrate due to stressed the bending deflection of plate neck or phenomenon of rupture that cause when braking, prevent brake pad and brake disc area of contact from diminishing, ensure the reliability of lining work.

In order to increase the heat diffusion area of lining, to accelerate the transmission of frictional heat, the free end of plate neck is provided with radiating structure 1.

The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
