Description

[0001] BRAKE DISC CONTAINING PHASE CHANGE MATERIAL

[0002] Technological Field:

[0003] This invention relates to a disc containing phase change material inside a metal disc that can prevent overheating, especially designed for use in the automotive field and also in the brake sections of automation systems.

[0004] State of the Art of the Technique:

[0005] Brake discs and pads used in the brake system are the equipment needed for the vehicle to slow down and stop. The brake disc is a tool that provides friction for the brake pads to stop, among these equipment that work in conjunction with each other. The heat generated during this friction damages the vehicle brake components, materials wear out over time due to heat, the disc and pad cannot perform their duties, and even noise when the vehicle slows down due to vibrations caused by heat. In high temperature conditions or continuous heavy braking, losses in braking power are observed in the brake pad systems due to heating. In addition, the brake system fluid can deteriorate due to heating, and deteriorated brake fluid can reduce braking performance and cause problems in the system. The heat generated at extremely high temperatures causes cracks and deformations in the brake pads and discs and leads to additional problems such as more time and cost for brake system maintenance and repair.

[0006] The patent application TR2023003837 describes brake systems that can be considered temperature control systems. The invention includes an application that converts the equipment used in braking into braking equipment that delays the temperature increase to prevent excessive heating during braking in vehicles and other automation systems from decreasing the braking performance. The invention may also include at least one temperature sensor that measures and transmits the temperature values of the brake discs, a processor that receives the temperature information of the brake discs from the temperature sensor and analyzes it using the smart learning technique, and creates a warning to the user if the temperature is above the determined thresholds as a result of this analysis, a display panel that shows the warning created by the processor to the user, and a database that stores the values analyzed by the processor.

[0007] The patent application mentioned above may include temperature sensors and software that controls the temperature values and collects data from the braking elements of the automation systems. This system can show temperature distributions instantly or as total data on a panel.

[0008] As a result, a new technology that can overcome the above-mentioned disadvantages is needed.

[0009] Description of the Invention:

[0010] As a result of the phase change material contained in the metal structure of the brake disc of the invention, it comes into play when the braking system exceeds a certain temperature (by absorbing a portion of the heat depending on the amount of application) and delays the overheating behavior. This feature provides the system with the advantage of additional braking or eliminating the risk for a period of time.

[0011] The brake disc of the invention has the capacity to absorb sensible and latent heat. In this way, it can effectively delay high temperatures that occur during braking. At the same time, the thermal stability of the brake disc has also been increased, it maintains temperature constant within a time period. Phase change material with high heat absorption capacity and thermal stability leads to improved braking performance. In addition, long-term utility of brake discs and pads will be possible with sufficient performance. Detailed Description of the Invention:

[0012] Air channels can be created on the discs used in the brake systems of vehicles, and the disc also contains phase change materials within the metal structure. During the vehicle's braking (repeating or long-term braking), the phase change material melts and absorbs some of the heat, delaying the overheating of the components used in the brake system and eliminating or reducing the possibility of an accident. The system in question will be obtained by adding the phase change material during or after the production of the disc.

[0013] Brake discs and pads heat transfer is optimized, and cooling performance increases with phase change material. The phase change materials that will work in this system can be any metal such as aluminum, magnesium, zinc, tin, lead, antimony, molybdenum or any metal alloys such as aluminum, copper, zinc, magnesium, and silicon in any composition ratio, 2- and 3-part alloys or any salts such as NaCl, KC1, KN03 that work in the same temperature range. The phase change material will melt and solidify because the brake disc reaches a temperature value over 300 degrees, allowing it to absorb some of the heat. The phase change material may be contained in any encapsulated form.
