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 is characterized in that: comprise brake drum, described brake drum is provided with the intake grill that is connected with brake drum inwall wind groove, adds wind-collection cover on the intake grill, on the brake drum and be provided with radiation hole.
Above-mentioned intake grill is 4～8 cone shape holes that outer imperial palace is little, about equidistant equidimension be divided into brake drum cylindrical miter angle place, intake grill is provided with about on the axletree.
Above-mentioned radiation hole is 4～8 clear openings, about equidistant equidimension be divided on the brake drum outer annular-stiffer, radiation hole is provided with about on the axletree.
Above-mentioned brake drum inwall wind groove is the wind groove of 4～8 3 millimeters deep, connects intake grill to radiation hole.
Be arranged with 16 stiffening ribs about above-mentioned brake drum drum face, stiffening rib is located at brake drum outer wall miter angle and between the stiffening rib inboard, is provided with about on the axletree to brake drum.
Above-mentioned intake grill aperture is 12～30 millimeters.
Above-mentioned radiation hole aperture is 12～30 millimeters.
Above-mentioned wind-collection cover is the low die parts in preceding high back, is arranged to be higher than car rim peep hole 4～10 centimeters.
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.
