Description
Technical field
The utility model is related to automobile technical field, and more particularly to a kind of brake block for reducing brake noise.
Background technology
In the properties of automobile, NVH (noise, vibration, sound vibration roughness) characteristic is to weigh car mass " soft " property
One key factor of energy index, and brake oil is the very important performance assessment criteria of one of which.Point during automobile brake
Cry both produces noise pollution, and the riding comfort of occupant is had a strong impact on again, damages the health of people.
Brake block is most important part in brake, its brake force performance that not only provide vehicle needs, while
There is excellent muting function.
In the prior art, brake block includes backboard and brake pad, and the back side of brake pad is connected on backboard, in brake pad
Front is provided with the fluting perpendicular to brake pad length direction, and the brake noise of this brake block is than larger, and thermal diffusivity is also not very good.
Utility model content
In view of this, the utility model provides a kind of brake block for reducing brake noise.
It is the brake block of the reduced brake noise that the utility model is provided up to above-mentioned advantage, including backboard and brake pad,
The back side of the brake pad is connected on the backboard, and the front of the brake pad is provided with two inclined flutings.
Further, the fluting is parallel to each other.
Further, described fluting inclines to the direction of advance of wheel.
Further, the fluting and the angle of wheel direction of advance are 20 °~75 °.
Further, the fluting and the angle of wheel direction of advance are 30 °~75 °.
Further, it is additionally provided with chamfering at least one end of the brake pad.
Further, the chamfering is circular arc chamfering.
Further, the radius of the chamfering is 20-30mm.
Further, the brake pad is integrated with backboard sintering.
Fluting set by disc surface of the present utility model can the radiating of auxiliary brake piece, and brake block can be discharged with braking
The dust that disk friction is produced, can reduce the brake noise of brake and the frictionally damage of brake disc and energy heat radiation performance.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram of the brake block of the reduced brake noise of an embodiment of the present utility model.
Fig. 2 is the top view of the brake block that can reduce brake noise.
Fig. 3 is the front view of the brake block that can reduce brake noise.
Specific embodiment
Below in conjunction with drawings and Examples, the utility model is further elaborated.It should be appreciated that this place is retouched
The specific embodiment stated only is used to explain the utility model, is not used to limit the utility model.
As Figure 1-3, it is possible to decrease the brake block of brake noise includes backboard 1 and brake pad 2.In the present embodiment, rub
Cleaning block 2 is made up of organic material, for example, it can be made by without asbestos organic material.Backboard 1 is steel plate.The back of the body of brake pad 2
Face is connected to the front of backboard 1, and the front of brake pad 2 is provided with fluting 21.Bloop (not shown) is provided with the back side of backboard 1.
In the present embodiment, fluting 21 is two inclined grooves being parallel to each other, its advance side for inclining angular divergence wheel
To (i.e. the tangential direction in vehicle wheel rotation direction).Angle between fluting 21 and wheel direction of advance is α, angle α is 20 °~
75 ° preferably, and angle α is 30 °~75 °.
In this embodiment, it is preferred that, also it is arranged with chamfering 22 at the two ends of brake pad 2.It is highly preferred that chamfering 22 is
Circular arc chamfering.The radius of the chamfering 22 is 20-30mm.
The brake block manufacturing process with regard to the reduced brake noise of the present embodiment is described in detail below.
The punching press of backboard 1 is completed according to design requirement first, the friction material mixture of brake pad 2 is sintered to backboard 1
Integrally, it is ensured that the adhesive strength of brake pad 2 and backboard 1.
It is placed on sintering finished in frock clamp, is oblique notched on the surface of brake pad 2 and obtain fluting 21, while to left and right
Both sides removal material forms circular arc chamfering 22 and can obtain brake block of the present utility model.
In vehicle travel process, driver can be braked according to road conditions, brake disc and brake block friction and produce certain
Temperature.Two flutings 21 being parallel to each other designed on brake pad 2, effectively can will produce heat to distribute on brake block,
Solve and failed because continuously braking the brake force for causing.21 parts of fluting can effectively excrete and brake disc rubs and produces simultaneously
Dust, solve because friction high temperature make dust sinter hard particles into and to it is hot when brake disc produce inordinate wear, and
Also brake noise is reduced to a certain extent.Additionally, the circular arc chamfering 22 that left and right is designed on brake pad 2, also solves because rising
Walk the brake noise for producing.
To sum up, brake block of the present utility model, can effectively reduce the brake noise of brake and the frictionally damage of brake disc
And can heat radiation performance.
Additionally, the angle of inclination of fluting 21, width and depth, and the size of chamfering can also be entered according to different vehicles
Row changes, so as to by the noise reduction for changing the intrinsic frequency of brake block to obtain optimal.
Additionally, in the present embodiment, being arranged with chamfering 22 at the two ends of brake pad 2, it is also possible to be only provided with its one end
Chamfering 22.Brake pad 2 with backboard 1 is bonded together by sintering, but it can also be fixed together by glue sticking.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this
Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
