Abstract
The invention relates to a brake disc with low noise which comprises a brake disc working surface and a flange disc, wherein the brake disc working surface and the flange disc are arranged splitedly, and are connected through a bolt and a nut; a radial gap is reserved between the brake disc working surface and the flange disc; and a spring gasket is arranged between the bolt and the brake working surface as well as between the nut and the brake disc working surface. According to the invention, the conical deformation of the existing brake disc can be avoided, and the non-uniform axial force when the brake disc DTV (digital television) is out of tolerance can be balanced, thereby reducing the brake noise effectively.
Description
Technical field
The present invention relates to a kind of automobile low noise brake disc.
Background technique
In the prior art, in the disclosed technological scheme of brake disc assembly (patent No. CN200580031242.6) as denomination of invention brake disc assembly (patent No. CN200480005022.1) and denomination of invention automotive wheel, brake disc comprises wheel hub, rotor and rubbing device, brake disc working surface and flange plate are one, the deficiency that exists is: as shown in Figure 4, taper deformation appears when brake disc is heated easily, make between brake disc working surface and the brake slipper to contact and become the line contact by face, cause brake disc, brake pads wear aggravation, brake noise is big; Because there is DTV (thickness difference) in the brake disc working surface, concrete branch radial thickness difference and axial thickness are poor, wherein the axial thickness difference is to brake disc noise, influence of vibration maximum, and when brake disc DTV was overproof, uneven axial force can cause the vibration and the big brake noise of brake disc when braking.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of low noise brake disc, can effectively reduce brake noise, prevents brake disc taper deformation.
Realize the object of the invention technological scheme:
A kind of low noise brake disc comprises brake disc working surface and flange plate, it is characterized in that: brake disc working surface and flange plate split are provided with, and the two connects by screw bolt and nut.
Leave radial clearance between brake disc working surface and the flange plate.
Be equipped with compression spring between bolt and the brake disc working surface and between nut and the brake disc working surface.
The inboard of brake disc working surface radially evenly is provided with semicircle orifice, the radially corresponding semicircle orifice that is provided with in the flange plate outside, and the semicircle orifice of aforementioned brake disc working surface and the semicircle orifice of flange plate form bolt connecting hole.
The inboard of brake disc working surface radially evenly is provided with 12 semicircle orifices, and the flange plate outside is radially corresponding to be provided with 12 semicircle orifices.
The brake disc working surface is connected by 12 bolts, 12 nuts with flange plate.
Compression spring is the butterfly spring pad.
The beneficial effect that the present invention has:
Because brake disc working surface of the present invention and flange plate split are provided with, leave radial clearance between brake disc working surface and the flange plate, the braking of brake disc work card is heated and can be radially outwards expanded, effectively avoided the taper deformation of existing brake disc, thereby the reduction brake noise reduces the wearing and tearing of brake disc, brake slipper.
Because brake disc working surface of the present invention and flange plate split are provided with, the brake disc working surface is connected by nut, bolt with flange plate, and be equipped with compression spring between bolt and the brake disc working surface and between nut and the brake disc working surface, when brake disc DTV is overproof, inhomogeneous axial pressure during braking will force the brake disc working surface to do small slip vertically, thereby effectively reduce brake noise.

Embodiment
As shown in Figure 2, brake disc working surface 1 and flange plate 2 split settings, the inboard of brake disc working surface radially evenly is provided with 12 semicircle orifices, radially corresponding 12 semicircle orifices, the semicircle orifice of aforementioned brake disc working surface and 12 bolt connecting holes of the semicircle orifice of flange plate formation of being provided with in the flange plate outside.As Fig. 1, shown in Figure 3, brake disc working surface 1 is connected with 12 fastening self-locking nuts 3 by 12 shearing clamping bolts 5 with flange plate 2, shear between clamping bolt 5 and the brake disc working surface 1 and be equipped with compression spring 4 between fastening self-locking nut 3 and the brake disc working surface 1, compression spring is the butterfly spring pad, leaves radial clearance between brake disc working surface and the flange plate.
As shown in Figure 5, outwards expand when the brake disc working surface is heated,, leave radial clearance between brake disc working surface and the flange plate because brake disc working surface and flange plate split are provided with, have only little heat to be delivered on the flange plate, so the thermal distortion of flange plate is less.Simultaneously, because the effect of butterfly spring pad, make axial pressing force little, therefore, the thermal expansion of brake disc working surface only can cause the increase in gap and can not pull flange plate, thereby the thermal expansion that makes the brake disc working surface belongs to the expansion pattern in the plane, can't cause the taper deformation of brake disc, thereby effectively reduce brake noise.
As shown in Figure 6, when brake disc DTV is overproof, because brake disc working surface and flange plate split are provided with, shear between clamping bolt and the brake disc working surface and be equipped with compression spring between fastening self-locking nut and the brake disc working surface, inhomogeneous axial pressure during braking will force the brake disc working surface axially to do small slip (this moment, compression spring was compressed) along flange plate, thereby the uneven axial force of balance effectively reduces brake noise.
