Abstract
The utility model discloses a spiral groove type vehicle brake drum with cooling fins and reinforced graphite rings. The spiral groove type vehicle brake drum with the cooling fins and the reinforced graphite rings comprises a drum body, wherein a rectangular spiral groove with a plurality of spiral lines is arranged on the inner wall of the drum body, a groove is arranged in the middle of the outer wall of the drum body, cooling fins which encircle the middle portion of the surface of the whole drum body are uniformly distributed in the groove, the cooling fins are of a triangle and are integrally connected with the drum body, a reinforced boss which is integrally connected with the outer wall of the drum body is arranged on the end portion of the outer wall of the drum body, a plurality of groups of caulking grooves which are alternately distributed are arranged on the reinforced boss, and graphite rings are arranged in the caulking grooves. The spiral groove type vehicle brake drum with the cooling fins and the reinforced graphite rings increases cooling area of the outer surface of the drum body by improving a traditional brake drum to add the triangle cooling fins in the middle of the outer wall of the drum body, improves cooling efficiency, and further improves surface strength of the drum body to a certain degree.
Description
Technical field
The utility model relates to auto parts machinery field, is specially a kind of spiral groove type automobile brake drum with radiating fin and enhancing graphite annulus.
Background technique
Brake drum is one of automobile brake parts, belongs to a part for brake system, and when brake, piston is exerted pressure to two pairs of half-moon-shaped brake shoes, makes it be adjacent to tympanum inwall, stops the rotation of wheel thereby produce to rub.The material of brake drum is generally HT200-300 (gray cast iron), and this kind of material can play the effect of heat radiation, increase frictional behaviour, reduction brake noise.At present, the production technology of brake drum blank is casting, due under the effect of the brake shoes friction of being everlasting and outwards spreading of brake drum, thereby brake drum can be from drum body port cracking, affect using effect and the working life of brake drum, in addition, because brake drum temperature is too high, can cause tube to be heated for a long time, thereby produce aging working life of reducing tire.
Model utility content
The technical problem that the utility model solves is to provide a kind of spiral groove type automobile brake drum with radiating fin and enhancing graphite annulus, solve traditional braking drum drum end of body strength deficiency, crackly problem, extended the working life of brake drum, the utility model has also improved the poor problem of traditional braking drum radiating condition simultaneously.
The technical problem that the utility model solves realizes by the following technical solutions:
With a spiral groove type automobile brake drum for radiating fin and enhancing graphite annulus, comprise bulging body, drum body inwall is provided with the rectangular coil groove of many helixes; The external wall of described drum middle part is provided with groove, is evenly equipped with the radiating fin around middle part, whole bulging surface in groove, and described radiating fin is triangular in shape and be connected with drum body one; The end of described bulging outer wall is provided with a reinforcement boss being connected with the external wall one of drum, is provided with some groups of caulking grooves spaced apart on described reinforcement boss, is provided with graphite annulus in caulking groove.
Further, the height of described radiating fin is lower than the degree of depth of groove.
The utility model, by traditional brake drum is improved, has been set up triangle radiating fin at the external wall of drum middle part, has increased the heat diffusion area of bulging external surface, has improved radiating efficiency, and has also increased to a certain extent the surface strength of bulging body; Also be provided with the reinforcement boss with graphite annulus group in the end of drum body simultaneously, on drum body, form an elastic buffer band, make brake drum be difficult for breaking, further extended the working life of brake drum.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model radiating fin.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of spiral groove type automobile brake drum with radiating fin and enhancing graphite annulus as shown in Figure 1 and Figure 2, comprise bulging body 1, drum body 1 inwall is provided with the rectangular coil groove 6 of many helixes, rectangular coil groove 6 can be used as cools down, the passage of heat absorption and heat extraction, in the time that trickle is lowered the temperature, trickle also can be taken away heat at the interior rapid flow of rectangular coil groove 6, and prevents that friction pair from skidding; Described bulging body 1 outer wall middle part is provided with groove 3, in groove 3, be evenly equipped with the radiating fin 2 around whole bulging body 1 middle part, surface, described radiating fin 2 is triangular in shape and be connected with drum body 1 one, uniform triangle radiating fin 2 enhances the heat diffusion area that has added bulging body 1 outer surface, improve radiating efficiency, and also increased to a certain extent the surface strength of bulging body 1; The end of described bulging body 1 outer wall is provided with a reinforcement boss 5 being connected with drum body 1 outer wall one, on described reinforcement boss 5, be provided with some groups of caulking grooves 4 spaced apart, in caulking groove 4, be provided with graphite annulus, graphite annulus has good toughness, can on drum body 1, form an elastic buffer band in the graphite annulus group of strengthening inlaying on boss 5, make brake drum be difficult for breaking, further extended the working life of brake drum.
In the utility model, the height of described radiating fin 2 is lower than the degree of depth of groove 3, to ensure working life and the radiating effect of radiating fin 2.
The utility model, by traditional brake drum is improved, has been set up triangle radiating fin at the external wall of drum middle part, has increased the heat diffusion area of bulging external surface, has improved radiating efficiency, and has also increased to a certain extent the surface strength of bulging body; Also be provided with the reinforcement boss with graphite annulus group in the end of drum body simultaneously, on drum body, form an elastic buffer band, make brake drum be difficult for breaking, further extended the working life of brake drum.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
