Abstract
The utility model relates to a novel ventilation brake disc, including inside brake face and outer brake lining, the inside brake face passes through the rib with outer brake lining and is connected, form the ventilation groove between rib and the rib, correspond on outer brake lining and/or the inside brake face and be equipped with a plurality of outer brake lining archs and/or inside brake face arch, inside and outside brake lining arch sets up respectively the ventilation inslot, inside and outside brake lining is protruding to be interrupted rectangular shape for continuous rectangular shape or by what single bump constituted. A plurality of outer brake linings are protruding to be set up or crisscross the setting with protruding correspondence of inside brake face. The rib is straight muscle, slash muscle or curve muscle. The utility model discloses the brake lining the is bellied ventilation cooling area in ventilation groove that has set up effective increase, the circumference and the radial temperature distribution that have improved the brake lining are inhomogeneous, have especially improved the regional brake lining area temperature nonuniform distribution's with the correspondence of non - rib of brake lining that the rib corresponds phenomenon.
Description
Technical field
This utility model relates to a kind of novel ventilated braking dish, belongs to automobile brake technical field.
Background technology
Braking dish is the rotation element of a kind of vehicle, and braking is to utilize the retaining elements such as brake(-holder) block with the surface rotating element by rubbing thus producing brake force, hinders vehicle movement or slows down the movement tendency of vehicle; It is to say, by braking the frictional force produced, make vehicle deceleration, stop or remain stationary state. It is based on this principle, when vehicle runs, makes the kinetic energy of vehicle be converted into heat energy by braking, it is achieved braking function, but in braking procedure, fricative heat energy causes braking dish temperature to raise. Braking dish is generally metal material or complex class material, such as casting pig, ceramic carbon fibre etc. These materials mechanical property when high temperature reduces, and coefficient of friction worsens, and causes brake efficiency to reduce, even produces brake fade.
Raise for improving braking dish temperature in use, improve the radiating effect of braking dish, the braking surface of existing braking dish includes inside brake face and outer braking surface, many ribs are used to connect between inside and outside braking surface, multiple heat dissipation ventilation groove is formed between rib and rib, although this improvement improves the ventilation effect of braking dish to a certain extent, and the venting plate of same size is compared entity dish and is also had the effect of loss of weight. But adopt the inside and outside braking surface that rib connects to there is the phenomenon that circumference is uneven with radial temperature profile, especially the braking surface region that rib is corresponding braking surface region is corresponding with non-rib, with radial temperature profile is uneven, braking surface circumference causes that braking surface circumference wall thickness variation is excessive, thermal deformation is big, this easily makes braking dish crack too early when frequently braking, and make braking take inventory in the hidden danger producing braking shake, affect safety and comfortableness that vehicle uses.
The problem uneven with radial temperature profile for improving above-mentioned braking surface circumference, the existing shape having by changing rib or the form such as braking surface boring and line realize.The shape of rib has straight muscle, length muscle, oblique line muscle, curve muscle, diamond muscle etc. But only changing the shape of rib, the temperature distributing disproportionation of braking surface improves really limited.
Utility model content
The deficiency that this utility model exists for prior art, it is provided that a kind of simple in construction, the novel ventilated braking dish of braking surface uniformity of temperature profile.
The technical scheme that this utility model solves above-mentioned technical problem is as follows: a kind of novel ventilated braking dish, including inside brake face and outer braking surface, described inside brake face is connected by rib with outer braking surface, ventilation slot is formed between described rib and rib, described outer braking surface and/or inside brake face are provided with multiple outer braking surface projection and/or inside brake face is protruding, and described inside and outside braking surface projection is separately positioned in described ventilation slot.
Further, multiple described outer braking surfaces are protruding and multiple described inside brake faces projection is correspondingly arranged or is crisscross arranged.
Further, described inside and outside braking surface projection is continuous strip or the interruption strip being made up of single salient point.
Further, described rib is straight muscle, oblique line muscle or curve muscle.
The beneficial effects of the utility model are: projection can be arranged on outer braking surface or on inside brake face, can also be simultaneously located on inside and outside braking surface, projection in ventilation slot can be intervally arranged in ventilation slot, it is as protruding in outer braking surface arranges an outer braking surface every a ventilation slot, and/or each ventilation slot arranges an inside brake face projection on inside brake face, then inside and outside braking surface projection can be correspondingly arranged, it is also possible to setting of staggering; In order to increase the area of dissipation in ventilation slot, projection can be covered with all of ventilation slot, it is achieved outer braking surface is protruding to be correspondingly arranged with inside brake face projection; In a word, the setting of this utility model braking surface projection is effectively increased the ventilation and heat area of ventilation slot, the circumference and the radial temperature profile that improve braking surface are uneven, especially improve the braking surface regional temperature phenomenon pockety that braking surface region corresponding to rib is corresponding with non-rib.

Detailed description of the invention
Below in conjunction with example, principle of the present utility model and feature being described, example is served only for explaining this utility model, is not intended to limit scope of the present utility model.
Embodiment 1, as depicted in figs. 1 and 2, a kind of novel ventilated braking dish, including inside brake face 2 and outer braking surface 1, described inside brake face 2 is connected by rib 3 with outer braking surface 1, forming ventilation slot 6 between described rib and rib, described outer braking surface 1 and/or inside brake face 2 are provided with multiple outer braking surface protruding 4 and/or inside brake face projection 5, and described inside and outside braking surface projection is separately positioned in described ventilation slot.
Multiple described outer braking surfaces are protruding and multiple described inside brake faces projection is correspondingly arranged.
Described inside and outside braking surface projection is continuous strip or the interruption strip being made up of single salient point.
The height of the inside and outside braking surface projection on inside and outside braking surface can be identical, it is also possible to different.
Described rib 3 is straight muscle, oblique line muscle or curve muscle.
Embodiment 2, as shown in Figure 3 and Figure 4, multiple described outer braking surfaces are protruding and multiple described inside brake faces projection is crisscross arranged. All the other are identical with embodiment 1 structure, are not going to repeat.
