Abstract
The utility model relates to an all-weather forced passive air cooling brake drum, which can cause the hot air of the brake drum to be quickly dropped away. The safe and efficient continuous use and brake are reached, and the service life of the brake drum is prolonged. Moreover, the operation is convenient and the cost is low. The utility model comprises a brake drum on which air inlets which are communicated with air slots on the inner wall of the brake drum which is provided with heat radiation holes; the air inlets are eight taper holes of which hole diameters are large outside and small inside, and are arranged at the position of the mitre angle of the outer circle of the brake drum in the way that the left and the right are equidistant and equidimensional; the heat radiation holes are ten taper holes of which the hole diameters are large outside and small inside, and are arranged on an outer reinforcing ring of the brake drum in the way that the left and the right are equidistant and equidimensional. The air slots on the inner wall of the brake drum are eight air slots of 3 cm depth, and are arranged in the brake drum right and left; the surface of the brake drum is provided with 16 reinforcing ribs left and right; the reinforcing ribs are arranged from the mitre angle of the outer wall of the brake drum to the inner side of the outer reinforcing rib of the brake drum.
Description
One, technical field:
The utility model relates to a kind of brake drum that is used for automobile, especially relates to the passive air-cooled brake drum of a kind of round-the-clock pressure.
Two, background technique:
Current domestic and international goods vehicle is as the important transportation traffic tool on land, and the rotatable member brake drum (drum brake) of braking system wherein is for being used for the vital instrument of the safe and effective ramp to stop of vehicle driving.The roadblock in urban district, hills, mountain area is many in addition, the ramp is many, bend is anxious because of temperature variation, for driving safety, the driver understands the continuous several times braking deceleration, apply the brakes, therefore drum brake sharply heats up because of the friction of doing manual work continuously, temperature is high to several Baidu, and high temperature is to effective braking hundred none profit of evil.In the very big emergency braking of severity of braking, drum brake has almost been born the task of the whole power of dissipation automobile, this moment is owing to have little time to spill in the atmosphere at the fricative heat of inside brake in short-term, cause the brake drum internal and external temperature to raise, the high more brake of temperature is insensitive more, invalid more, dangerous more.The speed per hour maximum limit of goods vehicle is 110 kilometers/hour for this reason.
Present truck man, in order to fall the effective braking brake of high temperature, the water spray system that is used for reequiping voluntarily more, be the cooling of brake drum trickle, increased light weight and also lack of standardization for this reason, this device can't be used because of freezing in subzero area in the winter time, because of the unexpected parts fault that brake high temperature produces, makes the brake failure inefficacy and the traffic accident of initiation is also of common occurrence.
Three, model utility content:
The utility model provides a kind of round-the-clock pressure passive air-cooled brake drum in order to solve the deficiency in the above-mentioned background technology, and it can make the hot gas of brake drum leave rapidly.Reach continuous safely and effectively apply the brakes, prolong its working life, and easy to use, and cost is low.
For achieving the above object, the technical solution adopted in the utility model is:
The passive air-cooled brake drum of a kind of round-the-clock pressure, its special way is: comprise brake drum, described brake drum is provided with the intake grill that is connected with brake drum inwall wind groove, on the brake drum and be provided with radiation hole.
Above-mentioned intake grill is the little cone shape hole of imperial palace outside eight apertures, about equidistant equidimension be divided into brake drum cylindrical miter angle place.
Above-mentioned radiation hole is the little cone shape hole of imperial palace outside ten apertures, about equidistant equidimension be divided on the brake drum outer annular-stiffer.
Above-mentioned brake drum inwall wind groove is eight 3 centimetres dark wind grooves, about be divided in the brake drum.
Be arranged with 16 stiffening ribs about above-mentioned brake drum drum face, stiffening rib is located at brake drum outer wall miter angle to brake drum between the stiffening rib inboard.
Above-mentioned intake grill aperture is 3-30 centimetre.
Above-mentioned radiation hole aperture is 10 centimetres.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
1, the hot gas of brake drum leaves rapidly by wind groove and radiation hole in the utility model.Reach continuous safely and effectively apply the brakes, prolong its working life.
2, it is little that the utility model low cost of manufacture, technology simply make former skidding drum change, and is applicable to the drum brake of various sizes.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is that the B of Fig. 1 is to view.
Among the figure, 1-radiation hole, 2-wind groove, 3-intake grill, 4-stiffening rib.
Five, embodiment:
Referring to Fig. 1, Fig. 2, Fig. 3, the utility model comprises brake drum, and the brake drum outer drum surface has 16 stiffening ribs 4, and stiffening rib 4 is located at brake drum outer wall miter angle to brake drum between the stiffening rib inboard.Equidistant equidimension is arranged with eight intake grills 3 about brake drum cylindrical miter angle place, intake grill 3 is the little cone shape hole of imperial palace outside eight apertures, directly be communicated with brake drum inwall wind groove 2, when being convenient to brake shoe and combining with the brake drum inwall, fricative temperature is through the wind groove, in the cold wind forced heat radiation that transmits, reach the purpose of cooling.Intake grill 3 apertures are 3-30 centimetre.Brake drum inwall wind groove 2 is eight 3 centimetres dark wind grooves, about be divided in the brake drum.The brake drum outer annular-stiffer is provided with radiation hole 1, and radiation hole 1 is the little cone shape hole of imperial palace outside ten apertures, about equidistant equidimension be divided on the brake drum outer annular-stiffer.The radiation hole aperture is 10 centimetres.The hot gas of brake drum leaves rapidly by this radiation hole.Reach continuous safely and effectively apply the brakes, prolong its working life.
