Abstract
The utility model relates to a kind of automobile brake disc preventing shriek, comprises outer disc, and with disc in flange one, also comprise the ventilated rib of spiral of Archimedes shape, ventilated rib is distributed between interior disc and outer disc.The utility model structure achieves the object reaching the generation of prevention brake squeal on the basis not affecting traditional performances such as braking force, ventilation and heat, structural strength.
Description
Technical field
The utility model discloses a kind of automobile brake disc, be specifically related to a kind of automobile brake disc preventing shriek.
Background technique
At present, disk braking system obtains applying more and more widely in the car, the main radial ventilated rib structure of automobile brake disc, be easy to when automobile brake send sharp-pointed one frequency system moving noise shriek, can reach more than 100dB (A), and frequency is higher, the non-constant of sound quality, make us being difficult to stand, cause that client's is fastidious and discontented.Disk braking system shriek has encouraged the unstable vibration mode of braking system to cause by the contact friction force between brake strip and brake disc, the unstable mode of elastomer mode to braking system of brake disc creates significant contribution, this unstable vibration mode has the ability of very strong absorption outside energy, make braking system produce strong high-frequency self-excitation vibration, thus emit a shrill cry.
Therefore, the major measure that prevention brake squeal occurs is the characteristics of mode of reasonable design brake disc self, to avoid the generation of above-mentioned unstable mode.The structure of the elastomer mode of brake disc self and brake disc itself is closely related, and traditional automobile brake disc structural design mainly considers the performances such as braking force, ventilation and heat, structural strength, does not usually consider the impact of brake disc mode on brake squeal.
Summary of the invention
The utility model object there is provided a kind of automobile brake disc preventing shriek, can realize preventing brake squeal on the basis not affecting traditional performances such as braking force, ventilation and heat, structural strength.
The technical solution of the utility model is as follows:
Prevent an automobile brake disc for shriek, comprise outer disc, with disc in flange one, also comprise the ventilated rib of spiral of Archimedes shape, ventilated rib is distributed between interior disc and outer disc.
The footpath, helix initial pole of described ventilated rib 2 is 40mm, and helix coefficient is 5mm/deg, and ventilated rib thickness is 6mm, and ventilated rib height is 9mm.
Described ventilated rib is 44.
Working principle of the present utility model is:
The brake disc that the utility model provides adopts the ventilated rib structure of spiral of Archimedes shape, the geometric parameter of ventilated rib is mainly: the coefficient of footpath, helix initial pole, helix, the number of ventilated rib, the height of ventilated rib and thickness etc., geometric parameter limits without determined amounts, and the elastomer modal distribution situation primarily of brake calipers and brake disc is determined.Improve according to braking system demand or reduce brake disc stiffness by itself, general rule is: ventilated rib thickness is larger, the elastomer mode of the more brake discs of number is higher, and brake disc stiffness by itself is higher; The height of spiral ventilated rib is higher (disc thickness is determined), and the elastomer mode of brake disc is lower, and brake disc stiffness by itself is lower.
Technique scheme tool of the present utility model has the following advantages:
By the adjustment to ventilated rib shape, change the elastomer mode of brake disc, the generation of automobile brake shriek can be reduced, and it is simple to have structure, each parameter is simple and easy to control, and manufacture cost and traditional braking dish are more or less the same, and have the advantage of very strong engineering practicability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is explained in detail.
As shown in Figure 1, a kind of automobile brake disc preventing shriek described in the utility model, comprises outer disc 1, and with disc 3 in flange 4 one, also comprise the ventilated rib 2 of spiral of Archimedes shape, ventilated rib 2 is distributed between interior disc 3 and outer disc 1.By adjusting stiffness by itself and the modal distribution of the parameter adjustment brake discs such as the geometrical shape of ventilated rib, number, height and width, thus avoid the shriek of the unstable mode generation of this braking system.
The footpath, initial pole of ventilated rib 2 is 40mm, and helix coefficient is 5mm/deg, and spiral ventilated rib number is 44, and ventilated rib thickness is 6mm, is highly 9mm, and brake disc elastomer modal distribution reaches the requirement of braking system modal distribution.
The structure of the utility model brake disc is simple, and each parameter is simple and easy to control, can reduce the generation of automobile brake shriek, 100dB (A) brake squeal incidence rate can be reduced to less than 5%, be adapted at various automobile is applied.
In sum, the utility model is by changing the geometric parameters such as the footpath, helix initial pole of brake disc ventilated rib, the coefficient of helix, the number of ventilated rib, the height of ventilated rib and thickness, the characteristics of mode of reasonable design brake disc self, to avoid the generation of unstable mode, serve and prevent from, when automobile brake, shriek occurs.
Claims (3)
