Description

Combined type carbon fiber brake disc

Technical field

The utility model relates to automobile brake technical fields, are especially a kind of combined type carbon fiber brake disc.

Background technique

Currently, conventional brake disc is usually a circular discoid body, the center of discoid body offers axis hole, axis hole Surrounding offers several mounting holes.When assembling, axis hole is matched with axletree, and mounting hole and vehicle are passed through by fastening bolt Wheel is fixed.

During normal vehicle operation, the side of brake caliper and brake disc has scheduled gap, at this point, braking clamp Pincers are contactless with brake disc, and brake disc is rotated with wheel, does not generate brake force；When needing vehicle deceleration or parking, Start brake apparatus, the brake caliper relative movement of brake disc two sides, and then brake disc is clamped, starts to make by frictional force It is dynamic, so that the revolving speed of brake disc is reduced or is stopped rotating, realizes the deceleration and parking purpose of vehicle.It is clear that brake Disk and brake caliper can generate a large amount of heat in friction process, if dispersed not in time, brake disc long-time workpiece After be also easy to produce deformation, influence the braking quality of vehicle.In addition, can be generated a large amount of in brake caliper and brake disc friction process Powder, and after powder is attached in the two sides disk of brake disc, also will affect the heat dissipation and vehicle braking of brake disc.

Utility model content

It is high, reasonable in design that the technical problems to be solved in the utility model is to provide a kind of intensity, and can be timely Heat dissipation, to guarantee the combined type carbon fiber brake disc of vehicle braking performances.

The technical solution of the utility model is to provide a kind of combined type carbon fiber brake disc having following structure, Including round brake disc ontology, brake disc ontology is made of two pieces of discs, and the center of two pieces of discs offers axis hole, the week of axis hole It encloses and offers several mounting holes, several reinforcing ribs inclined from inside to outside, the inclination of each reinforcing rib are provided between two pieces of discs Direction is consistent, and is equidistantly uniformly distributed along the circumference of disc, surrounds aeration flow jointly between adjacent said rib and two discs Road offers several ventilation holes at position of mounting hole on disc, and the quantity of ventilation hole and the quantity of vent flow path are equal, and The corresponding vent flow path of each ventilation hole, and communicated with corresponding vent flow path, it is provided on the lateral wall of two pieces of discs Several arc grooves, one end of arc groove extend to disc edge, two pieces of discs and reinforcing rib using carbon fibre material one Injection molding.

Combined type carbon fiber brake disc described in the utility model, wherein the ventilation hole is inclined hole, tilt angle 20 Degree.

Combined type carbon fiber brake disc described in the utility model, wherein the spacing between two pieces of discs is 1.5cm.

Combined type carbon fiber brake disc described in the utility model, wherein the depth of the arc groove is 2~3mm, wide Degree is 1.5~2.5mm.

After using the above structure, compared with prior art, the utility model combined type carbon fiber brake disc has following excellent Point：The reinforcing rib of setting and the vent flow path surrounded can force air pair by the centrifugal force of generation when braking disc spins Stream, i.e. air enter from vent flow path outer, are then discharged by ventilation hole, and so on, reach and dissipate in time to brake disc The purpose of heat, avoids the assembly of heat, and then ensure that the braking ability of vehicle；In brake process, the powder meeting of generation It is braked in clamp push-in arc groove, since one end of arc groove extends to disc edge, revolved in brake disc high speed When turning, powder can be attached to disk along arc groove to throwing away outside brake disc under the action of the centrifugal force so as to avoid powder Heat dissipation is influenced on face, while ensure that the coefficient of friction between brake caliper and brake disc, improves the reliability of braking；By Use carbon fibre material integrated injection molding in two pieces of discs and reinforcing rib, therefore intensity is higher, and the reinforcing rib being arranged in addition to Have the function of increasing heat dissipation area, can also enhance the intensity of brake disc, structure design is very reasonable.In addition, this reality Also has the advantages that light-weight, wear-resistant, corrosion-resistant, endurance and anti-aging with novel.

By vents design at inclined hole, and tilt angle is 20 degree, and heat dissipation effect can be made more preferable.

Spacing between two pieces of discs is 1.5cm, can effectively improve heat dissipation performance in the case where guaranteeing self-strength.

Specific embodiment

The utility model combined type carbon fiber brake disc is made with reference to the accompanying drawings and detailed description further detailed Explanation：

As depicted in figs. 1 and 2, in this embodiment, the utility model combined type carbon fiber brake disc includes circle Shape brake disc ontology, the brake disc ontology are made of two pieces of discs 1,5, the spacing between two pieces of discs 1,5 be 1.5cm, two pieces The center of disc 1,5 offers axis hole 7, and several mounting holes 8 are offered around axis hole 7.If being provided between two pieces of discs 1,5 Reinforcing rib 2 inclined from inside to outside is done, the inclined direction of each reinforcing rib 2 is consistent, and equidistantly uniformly divides along the circumference of disc 1,5 Cloth surrounds vent flow path 3 between adjacent said rib 2 and two discs 1,5 jointly.It is opened at 8 position of mounting hole on disc 1,5 Equipped with several ventilation holes 6, the quantity of ventilation hole 6 is equal with the quantity of vent flow path 3, and the corresponding ventilation of each ventilation hole 6 Runner 3, and communicated with corresponding vent flow path 3, ventilation hole 6 is inclined hole, and tilt angle is 20 degree.The outside of two pieces of discs 1,5 Several arc grooves 4 are provided on wall, one end of arc groove 4 extends to disc 1,5 edges, and the depth of arc groove 4 is 2 ~3mm, width are 1.5~2.5mm, and two pieces of discs 1,5 and reinforcing rib 2 use carbon fibre material integrated injection molding.

The reinforcing rib 2 of the utility model setting and the vent flow path 3 surrounded can be when braking disc spins, by generation Centrifugal force forces cross-ventilation, i.e. air enters from 3 outer of vent flow path, then discharged by ventilation hole 6, and so on, Achieve the purpose that radiate to brake disc in time, avoid the assembly of heat, and then ensure that the braking ability of vehicle；It was braking Cheng Zhong, the powder of generation can be braked in clamp push-in arc groove 4, since one end of arc groove 4 extends to disc edge, Therefore, in brake disc high speed rotation, powder under the action of the centrifugal force can along arc groove 4 to throwing away outside brake disc, from And avoid powder and be attached in disk and influence heat dissipation, while ensure that the coefficient of friction between brake caliper and brake disc, Improve the reliability of braking；Since two pieces of discs and reinforcing rib use carbon fibre material integrated injection molding, intensity compared with Height, and the reinforcing rib being arranged can also enhance the intensity of brake disc, structure is set in addition to having the function of increasing heat dissipation area It is very reasonable to count.In addition, the utility model also has the advantages that light-weight, wear-resistant, corrosion-resistant, endurance and anti-aging.

When vehicle is brought to a halt in fast state or is repeatedly braked in a short time, the performance of brake is not easy to fail, can To allow vehicle to obtain preferable braking effect, to promote the safety of vehicle.

Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this The various changes and improvements that the technical solution of utility model is made should all be fallen into the protection scope of the utility model.
