Description

Single-piece type dish

Technical Field

The invention relates to a single-piece disc, in particular to an integrally formed single-piece disc which is provided with an anti-locking brake system reading hole and has a concave-convex shape formed on the surface of the disc so as to increase the natural convection heat dissipation efficiency.

Background

The present "anti-lock brake system reading disc structure of locomotive" is as the patent of taiwan application No. 098139822, and the main structure thereof at least comprises a rim, a disc brake disc and a reading disc, wherein the rim has a hub, the hub is provided with a disc brake seat, a plurality of reading disc fixing seats are arranged around the disc brake seat, the disc brake disc is locked on the disc brake seat, and the reading disc is locked on the reading disc fixing seats, wherein, the length of the reading disc fixing seat on the hub is more than that of the disc brake seat, so that when the reading disc is locked on the reading disc fixing seat from the outer side of the disc brake disc, a gap can be maintained between the reading disc and the disc brake disc, the gap can block the high temperature of the disc brake disc, and the high temperature is prevented from being transmitted to the reading disc, so as to achieve the effect of preventing the reading disc from deforming; the main disadvantages of the structure are as follows: the disk brake disk and the reading disk are separately manufactured and assembled, and the manufacturing cost is overlarge.

The conventional "wheel speed detecting device and ring to be sensed" as in taiwan patent No. 105108089 is characterized in that: in the brake device, if the brake is operated for a long time, high heat will be generated between the friction material of the brake caliper and the brake disc, and the high heat will cause the brake disc and the rim to thermally expand. Even if the wheel speed detecting device generates stress to act on the pulse signal ring mounted part of the sensed ring due to thermal expansion and contraction of the brake disc and the rim caused by brake actuation, the bending part is arranged on the base wall of the sensed ring, so that the deformation of the base wall caused by the stress can be prevented by the bending part; the main disadvantages in its constitution are: the brake disc and the sensed ring are separately manufactured and assembled, which results in excessive manufacturing cost.

For the background of the hidden brake device, please refer to the taiwan patent application No. 107201583. The hidden brake device includes an engine assembly, a rim assembly, a brake assembly, a speed sensing plate and a speed sensor. The engine assembly is pivoted on the frame and comprises at least one first mounting part and one second mounting part, the wheel rim assembly is pivoted on the engine assembly, the brake assembly comprises a disc and a caliper, the disc is fixedly arranged on the wheel rim assembly, the caliper is fixedly arranged on the at least one first mounting part and clamps the disc, the speed sensing disc is fixedly arranged on the wheel rim assembly, and the speed sensor is fixedly arranged on the second mounting part and corresponds to the speed sensing disc; because the disk and the speed sensing disk are respectively fixed on the rim assembly, the manufacturing cost and the future maintenance cost are higher.

The prior ABS disk is faced after being assembled, for example: the problems of wind flow management and heat management are derived from a number of patents such as taiwan applications 091101719, 092220754, 093216851, 097210434, 098204455, 103200399, 104219471, 101116212, 105209205, 104122744,

106216191 and 105112977, the present invention can solve these problems together, and is very practical.

For a more detailed description of the processing method of the present invention, please refer to the following: firstly, providing a thin disc-shaped disc brake disc, and sequentially performing the steps of grinding and rounding the outer diameter surface region 1, processing heat dissipation holes, chamfering the outer diameter reference surface 11, double-side grinding an upper surface and a lower surface of the disc brake disc, double-side grinding the contact upper surface 12 and the contact lower surface 13 of the outer diameter surface region 1, and the like to manufacture a single-chip disc. Then, mechanical damage on the surface of the single-piece disk is removed by polishing, and double-side polishing and edge polishing of the outer diameter reference surface 11 are performed on the contact upper surface 12 and the contact lower surface 13 of the outer diameter surface region 1.

Subsequently, the inner diameter surface region 2 is sequentially processed by a plurality of second geometric pattern holes 24 to perform punching, grinding or single-side grinding of the inner diameter surface 23, and the recessed surface 22 of the inner diameter surface region 2 is processed lower than the surrounding surface by dry processing or dry etching while performing planarization and thinning processes, so as to form the inner diameter surface region 2. Then, the concave surface 22 and/or the inner diameter surface 23 of the inner diameter surface region 2 are roughened to form the small unit concave-convex heat dissipation structure 26 and the edge of the inner diameter reference surface 21 is polished.

The invention is particularly applicable to the upgrading of an existing disc brake disc replaced by a one-piece disc brake disc, although the invention may also be advantageously used to construct new one-piece discs. As mentioned above, structurally strong disc brake discs that are lightweight, have good heat dissipation properties, and are highly wear resistant, often require some type of external heat dissipation structure to maintain the discs at an appropriate temperature during operation. The heat dissipation structure of the monolithic disk provided by the present invention generally comprises an integrally formed metal structure having the small-unit concavo-convex heat dissipation structure 26 and the large-unit concavo-convex heat dissipation structure 34, which increases the surface area of the concave surface 22, the inner diameter surface 23, the support upper surface 32 and the support lower surface 33 for transferring heat to the air. In order to reduce the cost of the small-unit concave-convex heat dissipating structure 26 and the large-unit concave-convex heat dissipating structure 34, a molded iron or steel structure is generally used. By virtue of the structure of integrally forming the disc brake disc and the read disc (or the speed sensing disc) using dry machining or dry etching, the heat dissipation structure 26 of the small unit of concave-convex of the concave surface 22 and the inner diameter surface 23, and the heat dissipation structure on the large unit of concave-convex of the support upper surface 32 and the support lower surface 33 are simplified because no additional heat dissipation means need to be included to attach the disc brake disc.

The arrangement shapes of the small-unit concave-convex heat dissipation structure 26 and the large-unit concave-convex heat dissipation structure are spiral arrangement (helical arrangement), wheel arrangement (rounded arrangement), opportunity packing (change packing), zigzag arrangement (zigzag order), circular arrangement (circular circulation), mixed arrangement (circular circulation), and random arrangement (random circulation), so as to transfer and guide the heat of the small-unit concave-convex heat dissipation structure 26 and the large-unit concave-convex heat dissipation structure 34 to the air. Wherein, one side of the inner diameter surface region 2 is to form the inner diameter surface 23, the other side of the inner diameter surface region 2 is to have the concave surface 22 structure and a plurality of second geometric figure holes 24, and the surface is to present a small unit concave-convex heat dissipation structure 26 on one or both of the concave surface 22 and/or the inner diameter surface 23 of the inner diameter surface region 2; as shown in fig. 7 and 8, the supporting structure 31 is connected between the outer diameter surface region 1 and the inner diameter surface region 2, and is made of a good heat conducting material, and is integrally formed or combined with the outer diameter surface region 1 and the inner diameter surface region 2, the supporting structure 31 is disposed between the outer diameter surface region 1 and the inner diameter surface region 2 in a strip or sheet shape, and is used for being connected to a heat source region of the outer diameter surface region 1, so that the supporting upper surface 32 and the supporting lower surface 33 of the large-unit concave-convex heat dissipation structure 34 are used for transferring heat to the surface area of air; the outer and/or inner surface of the supporting structure 31 is further provided with a guiding hole 36 for passing the air flow, and the positioning position of the guiding hole 36 includes three or more than three guiding holes 36 annularly arranged from the supporting upper surface 32 to the supporting lower surface 33.

The present invention is directed to the heat dissipation requirements of the contact upper surface 12 and the contact lower surface 13, and the local heat dissipation when the outer diameter surface region 1 is used as a single-piece disk is initiated, the inner diameter surface region 2 and the middle support region 3 with heat conduction and flow guidance are used as surface areas for increasing the heat transfer from the concave surface 22, the inner diameter surface 23, the support upper surface 32 and the support lower surface 33 to the air, and further the support structure 31 is connected between the outer diameter surface region 1 and the inner diameter surface region 2, so as to assist the heat energy transferred to the middle support region 3 to dissipate heat to the surrounding air through the surface of the middle support region 3 and the surface of the support structure 31; and further, the supporting structure 31 is provided with the diversion holes 36 for air flow to pass through, so that the large-unit concave-convex heat dissipation structure 34 conducts convection heat dissipation through heat dissipation fluid.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
