Description

A kind of brake disc structure of diametral curve type ventilated rib

Technical field

The utility model relates to a kind of automotive brake components, more particularly, to a kind of system of diametral curve type ventilated rib Moving plate structure.

Background technique

Now with the rapid development of automobile industry, automobile factory is also higher and higher to the braking ability requirement of brake, and The thermal bearing capacity and cooling requirements of brake disc are an important factor for influencing braking ability；The design of conventional brake disk is mostly long The ventilated rib of strip, ventilated rib structure ventilation effect is weaker, and brake disc ventilated rib inboard and the temperature difference at outer ledge are larger, in this way Brake disc generates high temperature after braking, is unevenly distributed brake disc surface temperature, generates high temperature so as to cause brake disc and concentrates, Influence the service life of brake disc.The brake disc structure for using this diametral curve type ventilated rib at present, improves the ventilation of brake disc Ability and thermal bearing capacity.

Utility model content

Technical problem to be solved in the utility model is exactly that temperature distribution is non-uniform for brake disc, high temperature concentration phenomenon, A kind of diametral curve type ventilated rib structure for improving brake disc draught capacity is provided thus, effectively improves the logical of brake disc Wind energy power and thermal bearing capacity.

In order to solve the above-mentioned technical problem, the utility model adopts the following technical solution:

The brake disc of the utility model includes brake disc disk body, braking surface and ventilated rib, and brake disc disk body and braking surface are logical It crosses ventilated rib to be connected, ventilated rib is diametral curve type ventilated rib, specially equally distributed along brake disc circumferential plane helical form Muscle structure increases heating surface area by this special setting, and improve itself holds thermal energy power.

The ventilated rib by multiple arcs muscle structure it is circumferentially spaced be uniformly connected to, the muscle structure edge of all arcs The same hour hands back-flexing of clockwise/counterclockwise.

The inner end of all muscle structures radially is closed and is located on same circumference in the ventilated rib.

The outer end connection of all muscle structures radially is external in the ventilated rib and is located on same circumference.

The air inlet section of the ventilated rib structure of the utility model is greater than air outlet section.

The ventilated rib knot constitutes arc strip and connects both sides braking surface.

The beneficial effects of the utility model are as follows:

The shaped form ventilated rib structure of the utility model, is effectively promoted the draught capacity and bearing capacity of brake disc.

The shaped form ventilated rib structure of the utility model, increases the surface area of brake disc ventilated rib, improves brake disc The thermal bearing capacity of itself.

The shaped form ventilated rib structure of the utility model, air inlet section is greater than air outlet section, to improve braking The heat-sinking capability of disk reduces braking ability problem caused by the heat fading because of brake disc, avoids accident.

Fig. 2 is the half sectional view along ventilated rib of Fig. 1.

Fig. 3 is 4 schematic diagram of air outlet sectional dimension along ventilated rib.

Fig. 4 is 5 schematic diagram of air inlet sectional dimension along ventilated rib.

In figure: brake disc disk body 1 brakes facial 2, ventilated rib 3, air inlet sectional dimension 4, air outlet sectional dimension 5.

Specific embodiment

With reference to the accompanying drawings and detailed description, installation and use process are further described the utility model.

As shown in Figure 1, the brake disc disk body 1 of the utility model include braking face 2, ventilated rib 3 in succession two brakings face 2。

Specific implementation is formed by casting technique, the ventilated rib structure as shown in Figure 2, and ventilated rib 3 is diametral curve Type ventilated rib, specially there is one between the equally distributed muscle structure of 1 circumferential plane helical form of brake disc, any radiating ribs Fixed gap, is conducive to ventilation and heat, increases heating surface area by this special setting, improve itself holds thermal energy power.

As shown in Fig. 2, the radiating ribs of arc shape are presented in specific implementation, it is evenly arranged connection braking surface 2, each ventilation Preset clearance before muscle, ventilated rib 3 by multiple arcs muscle structure it is circumferentially spaced be uniformly connected to, the muscle knot of all arcs Structure the inner end closing radially of all muscle structures and is located in ventilated rib 3 along the same hour hands back-flexing of clockwise/counterclockwise On same circumference, the outer end connection of all muscle structures radially is external in ventilated rib 3 and is located on same circumference.

And as shown in Figure 3 and Figure 4.3 air inlet section 4 of ventilated rib structure is greater than air outlet section 5, increases contact table Area reduces risk of stress concentrations.
