Description
Technical field
The present invention relates to auto parts and components field, more particularly, relate to a kind of high temperature-proof with automobile brake drum structure of speeding.
Background technique
automobile since being born at the end of last century, more than 100 year of trials and hardships of having passed by.When automobile is convoy on single track with speeding, rear car follows the travelling state of front truck, and namely front truck and rear car reach information communication, and rear car is according to the information of front truck, car parameter differences before and after contrast, is scaled rear car and drives scheme and realize automatic Pilot.With speeding, automobile is also applied in logistics aspect, utilizes the unmanned transhipment realizing goods.Brake drum is arranged on speeding in automobile tire, for the braking of automobile.And along with the high speed rotating of tire, brake drum may the reason such as Yin Gaowen burst, and therefore causes traffic accident.In order to improve this problem, the existing outer surface at drum body arranges stiffening rib, and stiffening rib becomes spiral line type, but its effect is unsatisfactory.
Summary of the invention
Technical problem to be solved by this invention be to provide high temperature-proof with automobile brake drum structure of speeding, the structural stability of stiffening rib, and drum body good heat dissipation effect, brake drum can be avoided to burst.
The present invention's adopted technological scheme that solves the problem is:
High temperature-proof with automobile brake drum structure of speeding, comprise bulging body and the stiffening rib being arranged on bulging external surface, the cross section of described stiffening rib be trapezoidal and with the surface of contact of drum body on be provided with " V " type groove, water is provided with in described " V " type groove, described stiffening rib comprises multiple vertical strengthening ribs vertical with drum body sense of rotation and multiple oblique stiffening rib intersected with vertical strengthening ribs, described oblique stiffening rib and vertical strengthening ribs connect and compose triangle, described stiffening rib domatic on be provided with groove.The present invention improves on the basis of existing technology, one, optimizes, improve band wind effect, strengthen the stability of reinforcing rib structure the structure of stiffening rib and arrangement mode; Its two, stiffening rib arranges groove, increases the area of contact of stiffening rib and air, enhancing radiating effect; Its three, stiffening rib arranges " V " type groove, and water is set in " V " type groove, strengthen the heat absorbing property to drum body.The face at the domatic i.e. trapezoidal waist place of vertical stiffening rib and oblique stiffening rib.Stiffening rib effectively can improve the intensity of bulging body, also can be with wind in rotation process.Cross section be trapezoidal stiffening rib in the process of rotating with drum body, band wind is effective.The band wind principle of vertical stiffening rib of the present invention is similar to the band wind principle of fan blade, but some is different; Fan leaf band wind is the wind in a generation direction, and the present invention realizes wind, does not need wind is specifically flowed to the both sides of stiffening rib, only need produce wind and produce wind flow velocity soon.In the experiment to stiffening rib and drum body sense of rotation angled relationships, all the other conditions of this experiment control are all consistent, and only stiffening rib changes with drum body sense of rotation angle reading; Experiment proves, when stiffening rib is vertical with drum body sense of rotation, its band wind effect is best, and namely radiating effect is best.Oblique stiffening rib not only connects vertical strengthening ribs, plays fixation, also further enhancing radiating effect to its structure.Triangle is most stable structure, oblique stiffening rib and vertical strengthening ribs is connected into triangle, makes the structural stability of stiffening rib, and under the situation that band wind is effective, its structural stability, namely strengthens the wind loading rating of stiffening rib, makes the occasion that its applicable monsoon intensity is large.Stiffening rib arranges " V " type groove, makes stiffening rib be triangle with the gap of drum body time, further strengthen the stability of single reinforcing rib structure.Stiffening rib generally adopts metal material, and it has good thermal conductivity.In " V " type groove, water is set, " V " type groove is connected with drum body, namely water directly contacts with drum body, according to heat formula, Q=c*m*T, wherein Q is the heat absorbed, C is specific heat capacity, m is quality, and T is temperature difference, under same volume, for iron, the mass ratio 3 of metal and water, and specific heat of water holds and the specific heat ratio of metal is 9, the water of namely identical volume is compared with metallic iron, temperature rises one regularly, its absorbable heat is three times of iron, and the temperature of absorption drum body that can be more, can ensure the heat dissipating capacity of drum body.
As preferably, described stiffening rib comprise many first oblique stiffening ribs be parallel to each other and many be parallel to each other and intersect to form the second oblique stiffening rib of rhombus with the first oblique stiffening rib, described vertical strengthening ribs is positioned on the diagonal of rhombus.First oblique stiffening rib, between the second oblique stiffening rib and vertical strengthening ribs, form isosceles triangle, it is convenient to the setting of stiffening rib, namely in working process, first oblique stiffening rib and the second oblique stiffening rib are first set, be arranged on the diagonal of rhombus by vertical strengthening ribs, working process is simply orderly.
As preferably, the degree of depth of described " V " type groove is less than 2/3rds of the height of stiffening rib and the width of " V " type groove notch is less than stiffening rib and 2/3rds of drum body contact width.The degree of depth of " V " type groove is too dark or notch is too wide, makes stiffening rib wall too thin, makes stiffening rib mutability, therefore should ensure the intensity of stiffening rib.
Further, the degree of depth of described " V " type groove is 1/2nd of the height of stiffening rib and the width of " V " type groove notch is stiffening rib and 1/2nd of drum body contact width.
To sum up, the invention has the beneficial effects as follows:
1, vertical stiffening rib is set to consistent with the sense of rotation of drum body by the present invention, and its band wind is effective, and heat dissipation potential is strong, avoids the explosion of drum body drum.
2, stiffening rib of the present invention domatic on be provided with groove, groove increases the area of contact with air, namely strengthens radiating effect.
3, stiffening rib of the present invention oblique stiffening rib and vertically form triangle between stiffening rib, make the structural stability of stiffening rib, namely wind loading rating is strong.
4, stiffening rib of the present invention is provided with " V " type groove, and is provided with water in " V " type groove, enhance the heat absorbing property to drum body, improve the radiating effect of drum body.
