Abstract
A brake disc of vehicle comprises a fouling-hold groove which is installed on the surface of the disc, a vent hole which is installed in the fouling-hold groove, and two braking surfaces which are connected by a connector, and a cooling path which is formed between the two braking surfaces and connects with the vent hole. The connector distributes in radial from the disc centre; a plurality of independent cooling paths are formed between the two braking surfaces, and connect different vent hole respectively; the vent hole is installed at the bottom of the fouling-hold groove and also installed on the disc surface. The effective friction area of the brake disc is much bigger and the braking effect is much better under the condition of installing the same fouling-hold grooves and vent holes; meanwhile, the airflow which flows through the vent hole can be utilized to clean the fouling in the fouling-hold groove directly.
Description
Technical field
The utility model belongs to the Vehicle Engineering field, relates to vehicle brake, especially the brake disc structure of disk type braker.
Background technique
In the existing vehicle brake: the brake disc of disk type braker is provided with the scale-hold groove and the ventilation and heat group hole of space on the card of brake disc, the disclosed content of Chinese patent CN01261467 for example, the shortcoming of its existence is: because scale-hold groove and space, ventilation group hole, the quantity of the vent hole that is provided with on it is subjected to bigger restriction, causes ventilation effect relatively poor; If increase vent hole then can reduce effective friction area of brake disc, influence Security; In addition, the dirt that remove in its scale-hold groove is relatively more difficult.
The model utility content
The purpose of this utility model is to provide a kind of new air conditioners linkage structure, increases to ventilate, improve brake disc cooling effect, raising Braking efficiency, overcomes the above-mentioned shortcoming of prior art.
For achieving the above object, solution of the present utility model is: a kind of automobile brake disc, card is provided with scale-hold groove, comprises vent hole, it is characterized in that: described vent hole is arranged in the scale-hold groove.
Further, comprise two braking surfaces, connect that form cooling duct between two braking surfaces, this vent hole is communicated with cooling duct by connecting body.
This connecting body is radially distributed by the card center, forms some independently cooling ducts between two braking surfaces, is communicated with different vent holes separately.
This vent hole is opened in the bottom of scale-hold groove.
Also comprise the vent hole that is opened on the card.
Owing to adopted such scheme, the utlity model has following advantage: vent hole is opened in scale-hold groove, can either be held dirt, and under the situation that same quantity scale-hold groove, vent hole are set, effective friction area of its brake disc is bigger, and braking effect is better; The leeway that increases vent hole quantity is bigger, and cooling effect is better; Simultaneously, can also utilize the air-flow of the vent hole of flowing through directly to remove dirt in the scale-hold groove.

Embodiment
First embodiment of the present utility model, shown in Fig. 1-5, the card 8 of brake disc 1 is provided with the scale-hold groove 5 of some cambers along circumferential arrangement, has some vent holes 4 in the bottom of scale-hold groove 5.The centre of brake disc 1 is provided with some connecting bodys 3, links together by two braking surfaces of connecting body 3 with brake disc 1.Further, can form independently cooling duct 2 between two adjacent connecting bodys 3, each vent hole 4 communicates with cooling duct 2.The air-flow of cooling duct 2 can flow in the scale-hold groove 5 through vent hole 4, has cooled off brake disc 1 on the one hand, can also remove the dirt that accumulates in the scale-hold groove 5 with airflow flowing on the other hand.
Be illustrated in figure 4 as the worm's eye view of first embodiment's automobile brake disc, scale-hold groove 5 is arranged on the card 8, its radian direction also has vent hole 4 with shown in Figure 2 opposite on it.Fig. 5 be among Fig. 4 B-B to sectional view.
All vent holes 4 of first embodiment are all opened the bottom at scale-hold groove 5, in fact be not limited in this, as long as vent hole 4 is opened in scale-hold groove 5,, or be opened in scale-hold groove 5 bottoms and side simultaneously respectively so vent hole 4 also can be opened in the side of scale-hold groove 5;
Further, in order to increase effective friction area of brake disc, can reduce the quantity of scale-hold groove 5, simultaneously the vent hole 4 in scale-hold groove 5, vent hole directly can also be opened on the card second embodiment as shown in Figure 6: on the card 18 of brake disc 11 scale-hold groove 15 is arranged, have vent hole 14 on it, in addition, also directly have vent hole 16 on the card 18.
Scale-hold groove can also be straight line or other arbitrary shape except being above-mentioned arc, and its length also can extend to the edge of brake disc, and its quantity also can be provided with as required; Equally, the shape of vent hole can be arbitrarily, and quantity also can be decided according to actual conditions.
The above-mentioned description to embodiment is can understand and use the utility model for ease of those skilled in the art.The person skilled in the art obviously can make various modifications to these embodiments soon, and needn't pass through performing creative labour being applied among other embodiments in the General Principle of this explanation.Therefore, the utility model is not limited to the embodiment here, and those skilled in the art should be within protection domain of the present utility model for improvement and modification that the utility model is made according to announcement of the present utility model.
