Abstract
The utility model discloses a forced heat dissipation car brake drum, including the brake drum body, be provided with a plurality of oblique muscle for brake drum body axis slope at the outer peripheral surface of brake drum body. The forced heat dissipation automobile brake drum has good forced heat dissipation capacity, can effectively prevent the brake drum and the friction plate from being too high in temperature, simultaneously reduces the heat influence on a steel ring and a tire, prolongs the service life of the brake drum, the friction plate and the tire, effectively prevents accidents caused by cracking of the brake drum and tire burst, and improves the driving safety.
Description
Technical field
The utility model relates to automobile brake drum, and what relate in particular to is a kind of automobile brake drum that can forced heat radiation.
Background technique
At present, produce both at home and abroad the automobile brake drum drum body major part of using and be smooth outer surface, the outer surface of portioned product is equipped with the rib of the parallel to an axis of some vertical and brake drums.The brake drum of these structures has the following disadvantages:
(1) causes that easily brake drum damages, and causes braking failure.Can be during car brakeing because of a large amount of heats of friction-produced, the heat that produces when braking in heavy-load automobile braking suddenly or in the downhill path segment length time especially will be higher, these heats can not effectively be discharged, even there is the longitudinal rib structure also just to increase heat dissipating capacity, the heat that sheds is enclosed in all that row does not go out in the annular space of brake drum and wheel tyre bead, makes brake drum, friction plate temperature rise too high, causes that material structure changes, thereby cause brake drum, the be full of cracks of friction plate thermal fatigue, cause braking failure.The user who has waters water cooling for reducing the temperature employing, but can quicken the brake drum fatigue damage like this, can produce explosion when serious, brake drum is shortened working life, and cause traffic accident easily.
(2) cause easily and blow out.Because the heat that car brakeing produces all is enclosed in the annular space of brake drum outer ring and steel ring inner ring, so the steel ring temperature also increases and conducts to the tire that is contained on the steel ring.Rubber inner tube is heated for a long time, thereby can produce aging the reduction life-span, and because there is a not too little breach at the tyre valve place on the steel ring cylndrical surface, at this position, the heat direct radiation of brake drum is given tire and valve cock, thereby blows out, and causes serious accident.
The model utility content
At existing automobile brake drum above shortcomings, the purpose of this utility model is to provide a kind of automobile brake drum of forced heat radiation, this brake drum has the forced heat radiation function, can effectively prevent gathering of the heat that produces in the brake drum braking process, can prevent that brake drum, friction plate temperature rise are too high.
The forced heat radiation automobile brake drum that the utility model provides comprises automobile brake drum drum body, is provided with some the diagonal bars that tilt with respect to brake drum drum body axis at the external circumferential surface of brake drum drum.
Forced heat radiation automobile brake drum of the present utility model has following advantage with respect to existing automobile brake drum: owing at the automobile brake drum external peripheral surface diagonal bar is arranged, not only can improve the intensity of brake drum, the effect of increase rigidity significantly, also increase heat diffusion area simultaneously; And then be equivalent to turbofan with respect to the diagonal bar of the axis tilt of brake drum, the same with the air draft principle of fan, diagonal bar on the brake drum that rotates when automobile running can be with the row of the hot air between brake drum and the tyre rim to a side, hole from the tyre rim row is to atmosphere again, thereby can effectively reduce the brake drum temperature, also reduced simultaneously heat effects to steel ring and tire, improved the working life of brake drum, friction plate and tire, and effectively prevent from the accident that causes owing to brake drum be full of cracks, tyre explosion to have improved traveling security.
Description of drawings
Fig. 1 is the stereogram of forced heat radiation automobile brake drum of the present utility model;
Fig. 2 is a forced heat radiation automobile brake drum usage mode schematic representation;
Fig. 3 is the transverse section cut away view of diagonal bar.
Embodiment
Below in conjunction with the drawings and specific embodiments forced heat radiation automobile brake drum of the present utility model is described further.
As shown in Figure 1, on the external peripheral surface 11 of automobile brake drum drum body 1, be evenly equipped with some the diagonal bars 12 that tilt with respect to brake drum drum body axis.Diagonal bar 12 is cast into one with brake drum drum body 1, and its quantity is 4～40, promptly can reach effect preferably, and it is too many that material consumption is increased.The section configuration of diagonal bar as shown in Figure 3, it is 2 °～45 ° with the angle β of the external peripheral surface normal of brake drum that there are 85 °～90 ° angle, back 122 in diagonal bar 12 fronts 121 with the external circumferential surface 11 of drum; As shown in Figure 2, diagonal bar 12 is 10 °～80 ° with respect to the preferable slanted angle α of the bulging body axis of brake drum, and this structure relatively helps air draft, and its forced heat radiation is effective.As shown in Figure 2, the left and right sides brake drum 1,1 of automobile ' on diagonal bar 12,12 ' angle of inclination unanimity, direction opposite.
Automobile advances with direction shown in the arrow among Fig. 2, when left and right sides automobile brake drum drum body 1,1 ' rotations, and the diagonal bar 12,12 of its outer surface ' hot air is arranged to both sides as fan.
Claims (6)
