Abstract
The utility model relates to a braking member for an automotive brake, specifically to a heat dissipation brake drum, comprising a body (1) and a plurality of reinforcing ribs (3) disposed on the external cylindrical surface (2) of the body (1), wherein the reinforcing ribs (3) are in the shape of arcs. The reinforcing ribs (3) are in the shape of the arcs, so that the mobility of air among the reinforcing ribs is improved, resistance of the reinforcing ribs on air flow is reduced, exhaust of the air flow is facilitated, the heat dissipation effect of the brake drum is good, and the braking performance is improved indirectly.
Description
Technical field
The utility model relates to the brake component that a kind of automotive brake is used, and relates in particular to a kind of heat radiation brake drum.
Background technique
Brake drum is the ironcasting of the similar tambourine of a kind of shape, and it and tire are fixed and rotated with speed, are fricting working surface with its inner cylindrical surface, with brake shoe assembly composition friction pair.During braking, brake shoe contact brake drum inner cylindrical surface produces frictional force and makes car deceleration or keep state of rest.Brake drum should have enough intensity, rigidity and thermal capacity, and in braking process repeatedly, receive frictional force, thrust and heat effects and deform to prevent brake drum, even fatigue failure.Traditional brake drum external cylindrical surface is smooth surface or has reinforcing rib structure; Reinforcing rib structure adopts lineal shape usually, and the root of stiffening rib extends to wheel rim attachment face place, based on this structure; In order to obtain higher intensity, rigidity thermal capacity and radiating effect; Can only strengthen the quantity of the thickness or the increase stiffening rib of brake drum, cause brake drum overweight, manufacture cost increases.
In order to improve the radiating effect of brake drum; Also there is stiffening rib to be set to the oblique line structure; A kind of heat radiation brake drum is disclosed like Chinese utility model patent CN2828433Y; On the external cylindrical surface of brake drum, evenly distribute by the oblique rib of many convexities, this oblique rib and brake drum external cylindrical surface fuse.Through this structure, increased the heat diffusion area of brake drum, cause air flow, produce certain air cooling effect.But because the employing of oblique stiffening rib when brake drum rotates, will certainly produce certain windage, be unfavorable for the entering and the discharge of air, its radiating effect is relatively poor.
The model utility content
For solving the deficiency that exists in the existing technology, the utility model provides a kind of heat radiation brake drum that is beneficial to the entering and the discharge of air, and it has better heat dispersion.
Be to realize above-mentioned purpose, the heat radiation brake drum of the utility model comprises body, is arranged on a plurality of stiffening ribs on the external cylindrical surface of body, and described stiffening rib is a camber line shape.
As qualification to aforesaid way, described each stiffening rib spaced set.
As the further qualification to the utility model, described stiffening rib is a corner shape.
As the qualification to aforesaid way, the root of described stiffening rib is vertical with the wheel rim attachment face of body, and the bight of stiffening rib and the external cylindrical surface of body are tangent.
Adopt technique scheme, be set to camber line shape, strengthened the flowability of gas between stiffening rib, reduced the resistance of stiffening rib, help the discharge of air-flow air-flow through stiffening rib; When stiffening rib was made as corner shape, air-flow can enter between two adjacent stiffening ribs in unobstructed bight from stiffening rib, and under the slight drag of camber line shape stiffening rib is flow backwards, discharged, and its radiating effect is better, has improved braking ability indirectly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify:
Fig. 1 is a perspective view shown in the utility model embodiment;
Fig. 2 is the plan view of Fig. 1.
Among the figure:
1, body; 2, external cylindrical surface; 3, stiffening rib; 31, root; 32, bight; 4, wheel rim attachment face; 5, interior rubbing surface; 6, passage.
Embodiment
The heat radiation brake drum of the utility model, it is to be camber line shape with existing stiffening rib shaped design, being beneficial to the entering and the discharge of air through this shape, and then reaches better radiating effect and braking ability.Based on this thought; The heat radiation brake drum of present embodiment, by Fig. 1, shown in Figure 2, it comprises body 1; Body 1 whole one-tenth tambourine shape; Its inside has circular interior rubbing surface 5, and its outside external cylindrical surface 2 is provided with the stiffening rib 3 of a plurality of evaginations, is wheel rim attachment face 4 in body 1 its right end face as shown in Figure 2.Spaced set between each stiffening rib 3, and each stiffening rib 3 is a corner shape.
Stiffening rib 3 is on concrete structure; The wheel rim attachment face 4 vertical settings of its root 31 and body 1; The bight 32 of stiffening rib 3 and the external cylindrical surface 2 tangent settings of body 1; By the gradually wide transition of bight 32 to root 31 circular arcs, like this, between two adjacent stiffening ribs 3, form the passage 6 that air-flow is led.When brake drum carried out the circumference rotation, air-flow contacted with body 1 along the tangent direction of external cylindrical surface 2, at this moment; Because the external cylindrical surface 2 of stiffening rib 3 evagination bodies 1 is provided with, and bight 32 is identical with the tangential of external cylindrical surface 2, like this; Air-flow will be a guiding with bight 32 to greatest extent, enters in the passage 6 between two adjacent stiffening ribs 3, under the arcuate guide of passage 6; The passage place that is made up of the root of two adjacent stiffening ribs 3 discharges, and it effectively raises radiating effect.
Claims (4)
1. a heat radiation brake drum comprises body (1), is arranged on a plurality of stiffening ribs (3) on the external cylindrical surface (2) of body (1), and it is characterized in that: described stiffening rib (3) is camber line shape.
