Description
Technical field
It the utility model is related to automobile component manufacturing technology field；Concretely relate to a kind of wire casing of braking automobile
The brake disc of cross distribution.
Background technology
Brake disc is the fricting couple piece of disk brake, in addition to it should have as the strength and stiffness required for component, also
Should there are as high as possible and stable coefficient of friction, and appropriate wearability, heat resistance, thermal diffusivity and thermal capacity etc..At this stage
Brake disc is to be connected and composed by the skidding end face at both ends by the reinforcement between it.In brake of motor-driven vehicle braking procedure
In, by the braking end face forceful contact friction at brake shoes and brake disc both ends, brake control power is formed, realizes motor vehicles
Timely stopping under steam.Shortcomings：First, the motor vehicles brake system of (or over long distances) for a long time in the process of moving
Dynamic, brake shoes and heat caused by brake disc skidding severe friction, ventilation and heat cooling-down effect is poor, causes brakes
Overheat and produce skidding " locking " phenomenon, influence normal vehicle operation.Second, brake shoes is severe by the external world with brake disc
The influence of working environment, easy adhesion machine oil, dust or sand grains；Due to the lubrication of machine oil, reduce brake shoes and brake
The frictional force of disk skidding, brake failure is quick reliable, have impact on safety traffic；Therefore people often set wire casing in rubbing surface
To increase frictional force, but set wire casing to substantially reduce the intensity of disk body afterwards, how to reduce influence of the wire casing to disk body intensity
It is technical problem urgently to be resolved hurrily.
The content of the invention
The purpose of this utility model is exactly to solve technical problem present in prior art, provides a kind of wire casing cross distribution
Brake disc, including wheel hub 4, be connected as a single entity with the wheel hub 4 and to the first disk body 1 extended around, the wheel hub 4 it is outer,
It is be arranged in parallel the second disk body 2 with first disk body 1, air inlet 21, institute is present between second disk body 2 and the wheel hub 4
State and be connected as a single entity between the second disk body 2 and first disk body 1 by equally distributed reinforcement 3, shape between the reinforcement 3
Into ventilating duct；The outer face of first disk body 1 and the outer face of second disk body 2 are rubbing surface, are set on the rubbing surface
Put increase frictional force and the wire casing of dirt can be held, totally four groups and along the circumferential crossing distribution of the rubbing surface, every group of the wire casing
The wire casing unit 5 includes the first arc groove 51, the second arc groove 52, the 3rd arc groove 53 and the 4th arc groove 54, and described
One arc groove 51 and the second arc groove 52, the 3rd arc groove 53 and the 4th arc groove 54 are on passing through the one of the center of circle of wheel hub 4
Bar straight line specular, the arc groove 52 of first arc groove 51 and second with one heart and the center of circle of the two be located on this straight line and
Outside the disk body 2 of the first disk body 1 or second；3rd arc groove 53 and the 4th arc groove 54 are on passing through the wheel
The straight line specular in the center of circle of hub 4, the center of circle of the two are deviateed on this straight line and are located at the disk of the first disk body 1 or second
Within body 2.
Further, the two of first arc groove 51, the second arc groove 52, the 3rd arc groove 53 or the 4th arc groove 54
End is respectively positioned within the rubbing surface without intersecting with the edge of the rubbing surface.
Further, section of first arc groove 51, the second arc groove 52, the 3rd arc groove 53 or the 4th arc groove 54
Face is shaped as the isosceles triangle of drift angle arc transition.
The utility model takes above-mentioned technical proposal, on the one hand radiates more preferable, another aspect wire casing increasing friction force, improves
Braking ability, but the shape and arrangement mode of wire casing uniqueness, it is little to brake disc intensity effect, to the even wearing of shoe plate；It is real
It is sensitive reliable to have showed brake, ensure that vehicle safe driving；Brakes component wear is alleviated, improves service life.

Fig. 2 is Fig. 1 profile；
Fig. 3 is the partial enlarged drawing at K-K in Fig. 1.
Embodiment
A kind of brake disc of wire casing cross distribution, casting the disk body of processing includes wheel hub 4, is connected as a single entity with the wheel hub 4
And to the first disk body 1 extended around, the wheel hub 4 is outer, be arranged in parallel the second disk body 2 with first disk body 1, described the
Air inlet 21 between two disk bodies 2 and the wheel hub 4 be present, by uniformly dividing between second disk body 2 and first disk body 1
The reinforcement 3 of cloth is connected as a single entity, and ventilating duct is formed between the reinforcement 3；Radiating is more preferable；The outer face of first disk body 1
Outer face with second disk body 2 is rubbing surface, sets increase frictional force on the rubbing surface and can hold the wire casing of dirt, improves
Braking ability, totally four groups and along the circumferential crossing distribution of the rubbing surface of the wire casing, wire casing unit 5 described in every group include the
One arc groove 51, the second arc groove 52, the 3rd arc groove 53 and the 4th arc groove 54, the camber line of the first arc groove 51 and second
Groove 52, the 3rd arc groove 53 and the 4th arc groove 54 are on the straight line specular by the center of circle of wheel hub 4, and described
One arc groove 51 and the second arc groove 52 are with one heart and the center of circle of the two is located on this article of straight line and is located at first disk body 1 or the
Outside two disk bodies 2；3rd arc groove 53 and the 4th arc groove 54 are on the straight line mirror image by the center of circle of wheel hub 4
Symmetrically, the center of circle of the two is deviateed on this straight line and within the disk body 2 of the first disk body 1 or second.First arc groove 51
It is located at the second arc groove 52 on same circle, convenient processing, increasing friction force, improves four groups of wire casing cross-shaped arrangements of braking ability
Mode, the wire casing in every group is symmetrical, and on the one hand little to brake disc intensity effect, the abrasion on the other hand to shoe plate is equal
It is even；Also help the machine oil being accumulated in wire casing or dust, sand grains are moved to one end and discharged.First arc groove 51, second
The both ends of arc groove 52, the 3rd arc groove 53 or the 4th arc groove 54 be respectively positioned within the rubbing surface without with the rubbing surface
Edge intersect.The influence degree to disk body intensity can so be reduced.First arc groove 51, the second arc groove the 52, the 3rd
The cross sectional shape of the arc groove 54 of arc groove 53 or the 4th is the isosceles triangle of drift angle arc transition.Such shape is advantageous to greatly
Reduce the concentration of online trench bottom stress greatly, reduce the influence opened up after wire casing to disk body intensity, extend brake disc uses the longevity
Life.
