In FIG:
1, brake drum body, 2, installation shaft, 3, chamfering, 4, radiating fin, 5, boss, 6, radiation hole.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Please refer to Fig. 1, in a kind of embodiment, brake drum provided by the utility model, comprise brake drum body 1, one end of brake drum body 1 is connected with installation shaft 2, and the sidewall of brake drum body 1 is provided with radiating fin 4, and radiating fin 4 is provided with several along the circumference of brake drum body 1, and protruding to the direction at the center away from brake drum body, the radiating fin axis of radiating fin 4 is crossing with the body axis of brake drum body 1 in the radiating fin projection of the shaft section of brake drum body 1.
Above-described embodiment is by outwards arranging the radiating fin of (outwards referring to the direction away from the center of brake drum body) projection at the outer wall of brake drum body 1, and it is crossing with body axis to make the radiating fin of the radiating fin axis of radiating fin project, this kind is arranged, both heat diffusion area was increased, and radiating fin 4 adapts to the mobile phase of air, the heat that braking is produced sheds as early as possible, ensures the validity of braking, improves the Security of driving; This kind of structure can play again the effect of stiffening rib simultaneously, improves the intensity of brake drum body 1.
Radiating fin projection is 15 degree with body axis angulation.The radiating fin 4 of this angle can adapt to the air mobile phase of brake drum surface in vehicle movement process, improves radiating effect further.Radiating fin projection can be also other angle with body axis, as 5 degree, and 10 degree etc.
Radiating fin 4 is S-type, and radiating fin axis is the line of two end points of S type.In the process that this structure rotates at brake drum, radiating fin 4, just as the flabellum of fan, can increase the flowing velocity of air-flow between brake drum and wheel rim, improve radiating effect further.Certain radiating fin 4 also can be other shape, as straight line type or other curve shape.
The intersection rounding of the sidewall of radiating fin 4 and brake drum body 1.Improved the intensity of radiating fin 4 by fillet design, extend its working life.
The pattern draft of radiating fin 4 is 45 degree.This structure both can facilitate the shaping of radiating fin 4, can increase again the flowing velocity of air further.
Radiating fin 4 is at least provided with 16, and is uniformly distributed along the circumference of brake drum body 1.This kind of setting better can play radiating effect, and radiating effect is even.Radiating fin 4 also can be provided with three, four or 17,18; Also can along the circumferential non-uniform Distribution of brake drum body 1.
Radiating fin 4 is wedge-shaped structure along the direction of body axis, and wedge-shaped structure 4 reduces along the radial dimension of brake drum body near the direction of installation shaft 2.Designed by wedge-shaped structure, air-flow can be made to be close to the surface flowing of brake drum body 1, increase the heat dissipation potential of braking.
The key groove of wedge-shaped structure is 15 degree.This angle can make heat dissipation potential better.
Brake drum body 1 is conical structure, and the small end of conical structure is near installation shaft 2; Radiating fin 4 runs through the whole sidewall of conical structure.By cone structure, only need arrange along the consistent radiating fin 4 of the radial dimension of brake drum body 1 at its sidewall, the vibrational power flow of radiating fin 4 can be facilitated, be convenient to manufacture.
The cone angle of conical structure is 30 degree.Namely in order to meet the setting of key groove 15 degree, the manufacturing process of radiating fin 4 is simplified further.
Brake drum body 1 and installation shaft 2 are by chamfering 3 transition.This structure can improve the intensity of brake drum.
Chamfering 3 is provided with radiation hole 6.This structure can either make friction plate and the fricative chip of brake drum discharge as early as possible, can accelerate heat dissipation rate again.
Chamfering 3 is provided with boss 5, and radiation hole 6 is located at boss 5.Boss structure can play reinforing function, improves the intensity of brake drum further.
Radiation hole 6 is circumferentially with several along brake drum body 1.Multiple radiation hole 6 can improve heat dissipation potential further.
Radiation hole 6 is at least provided with eight, and is uniformly distributed along the circumference of brake drum body 1.This structure makes the heat radiation of brake drum even, and reaches good radiating effect.
The number of boss 5 is identical with radiation hole 6 number, and namely each radiation hole 6 is all arranged at a boss 5, to improve the intensity of brake drum further, plays the effect of heat radiation simultaneously.
Although the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and only by the restriction of claim, those of ordinary skill in the art can easily modify to it and change, but do not leave essential idea of the present utility model and scope.
