Description
Title of the invention: System and method for heating tires Technical field of the invention
[0001] The present invention relates to heating systems intended to place at least one tire at a predetermined setpoint temperature.
[0002] The invention also relates to a method of heating tires to place at least one tire at a predetermined setpoint temperature. State of the art
[0003] In the field of motorsport, and more generally in the field of motorsports, it is well known that controlling tire pressure and temperature is essential to ensure optimal performance on the road and / or efficient tire use. Indeed, a tire's behavior on the road will vary depending on its temperature and pressure. Given the significant stresses placed on tires in motorsports, it is crucial to guarantee precise and optimal temperature and pressure conditions.
[0004] Furthermore, in order to best control a vehicle, it is preferable to ensure uniform temperature and pressure between each of the vehicle's tires. In the case of a competition, it is common practice to have different temperatures and pressures for each tire at the start of an event.
[0005] For this purpose, it is known in the prior art to provide tire warmers in the form of heated blankets or a heated cabin. These systems are configured to bring the tires to an optimal temperature for racing.
[0006] Although these solutions are satisfactory in that they heat the tires, they generally do not guarantee temperature uniformity between all tires. This is because each tire warmer is independent. Furthermore, these warmers do not heat the rims. Consequently, significant heat loss generally occurs.
[0007] In the case of heated tire cabinets, it is very difficult to guarantee a stable heating temperature since the heat source is a burner. It is therefore difficult to guarantee that the tire has not exceeded the manufacturer's heating tolerances (between 90°C and 100°C depending on the model).
[0008] There is therefore a need to find a system capable of heating a set of tires to a predetermined temperature with high precision and high temperature homogeneity between the tires of the set of tires.

[0018] The present invention aims to provide a solution that addresses all or part of the aforementioned problems. This goal can be achieved through the implementation of a heating system designed to bring at least one tire to a predetermined setpoint temperature, the heating system comprising: - at least one closed heating chamber internally delimiting an internal volume to receive said at least one tire; - a temperature control system at least partially disposed in the heating chamber, comprising at least one heating device and at least one temperature sensor, said heating device being configured to heat the air contained in the internal volume of the heating chamber, said at least one temperature sensor being configured to measure an internal temperature prevailing in the internal volume of the heating chamber; the temperature control system being further configured to activate the heating device when the internal temperature measured by the temperature sensor is strictly lower than the setpoint temperature; the heating device being an electrically powered heating device comprising at least one electrical resistance. The previously described provisions allow for the development of a tire heating system that provides efficient and precise heating of tires to a predetermined set temperature while minimizing energy consumption and protecting users of the heating system. In fact, using at least one electric heating element allows for heating a set of four tires with a power consumption of less than 2000 W. The heating system may also have one or more of the following characteristics, taken alone or in combination. In one embodiment, the heating device comprises three electrical resistances. For example, these three electrical resistances are uniformly distributed over a receiving surface of the heating chamber. According to one embodiment, the receiving surface is arranged at the bottom of the heating chamber in the direction of gravity. According to one embodiment, the tires are intended to be placed above the electrical resistors in the direction of gravity. According to one embodiment, at least one electrical resistance is an electrical resistance of 1000 W. According to one embodiment, the internal volume of the heating chamber defines a housing intended to receive the tires.
[0019] According to one embodiment, the temperature sensor includes a temperature probe configured to measure a temperature inside one of the tires.
[0020] Generally, the heating system is configured to heat at least two tires and in particular four tires.
[0021] According to one embodiment, the setpoint temperature is between 70°C and 100°C, in particular between 75°C and 85°C, and in particular substantially equal to 80°C.
[0022] According to one embodiment, the temperature control system includes a first temperature sensor for measuring the temperature inside a first tire, and a second temperature sensor for measuring the temperature inside a second tire.
[0023] In this way, it is possible to have a precise measurement of the temperature prevailing in each of the tires, it is therefore possible to control the homogeneity of the heating.
[0024] According to one embodiment, the temperature control system includes at least one fan configured to agitate the air contained in the internal volume of the heating chamber to homogenize the internal temperature prevailing in the internal volume of the heating chamber.
[0025] Thus, it is possible to act on the homogeneity of temperature inside the enclosure, the placement of the tires at the set temperature is thus more reliable and more precise.
[0026] According to one embodiment, the temperature control system includes at least one upper fan disposed above the housing intended to receive the tires, in the direction of gravity.
[0027] According to one embodiment, at least one upper fan is configured to direct a flow of hot air from the rims of the tires towards the walls of the heating enclosure.
[0028] According to one embodiment, the temperature control system includes at least one lower fan disposed under the housing intended to receive the tires, in the direction of gravity.
[0029] According to one embodiment, said at least one lower fan is disposed on a wall adjacent to the receiving surface. In this way, it is possible to prevent electrical resistance from damaging the at least one lower fan.
[0030] Advantageously, at least one lower fan is in fluidic communication with a guide duct configured to direct air towards the tire rims. Thus, at least one lower fan can be configured to blow air horizontally, and the guide duct allows a flow of hot air to be directed towards the rims, in a direction opposite to gravity.
[0031] Thus, the spatial distribution of the upper and lower fans allows for better homogenization of the internal temperature within the heating chamber. Furthermore, the airflow is directed by at least one lower fan towards the rims, and by at least one upper fan towards the walls of the heating chamber, creating an air circulation circuit within the chamber. This optimizes tire heating.
[0032] According to one embodiment, the heating system further includes a pressure control system comprising at least one valve and at least one pressure sensor, said at least one valve being intended to allow or alternatively prohibit the inflation of one of the tires, to increase or decrease an inflation pressure prevailing inside said tire, the pressure sensor being intended to measure said inflation pressure.
[0033] Thus, it is possible to adjust tire pressure at the same time as tire temperature. This allows tires to be prepared for a motor race.
[0034] According to one embodiment, said at least one valve is a valve operated manually by a user.
[0035] According to one embodiment, the pressure control system includes a pressure valve and a pressure sensor associated with each tire, the heating system including a control unit configured to receive a pressure value from each of the pressure sensors and to selectively actuate each pressure valve according to the pressure difference existing between the pressure values communicated by the pressure sensors, in such a way as to set a pressure difference between the two tires less than 0.05 bar, and in particular less than 0.01 bar.
[0036] Thus, it is possible to guarantee a homogeneous distribution of pressure in the tires before they leave the heating chamber.
[0037] H is well understood that one bar is equal to 105 Pa.
[0038] According to one embodiment, the control unit is configured to selectively actuate each pressure valve automatically, for example according to an algorithm stored in a memory of the control unit.
[0039] According to one embodiment, the heating system further comprises a tire support comprising a plurality of receiving planes and at least one spacer separating two receiving planes, each plane of the plurality of receiving planes being intended to receive a tire.
[0040] In this way, storing the tires in the heating chamber is facilitated and stable for user safety. Furthermore, the presence of a spacer on each receiving platform allows the tires to be separated to ensure proper air circulation, especially when a plurality of tires are housed in the internal volume of the heating chamber.
[0041] According to one embodiment, the heating system comprises a first heating chamber intended to receive four tires, and a second heating chamber intended to receive four other tires.
[0042] In this way, it is possible to maximize the number of tires that can be heated by the heating system.
[0043] It is well understood that the number of heating devices, the number of temperature sensors, the number of valves, the number of fans, and the number of pressure sensors is multiplied by the number of heating chambers, to equip all the heating chambers.
[0044] The object of the invention can also be achieved by implementing a tire heating method to place at least one tire at a predetermined setpoint temperature, the heating method comprising the following successive steps: - a step of making available a heating system as described above; - a preheating stage using electrical energy, in which the heating device is activated to heat the internal volume of the heating chamber to a temperature substantially equal to the setpoint temperature; - an introduction step, in which said at least one tire is introduced into the internal volume of the heating chamber; - a heating stage by electrical energy in which the temperature control system maintains the internal temperature of the internal volume at a temperature substantially equal to the setpoint temperature in the internal volume for a predetermined heating time.
[0045] The provisions described above make it possible to propose a heating method for precisely heating tires, with efficient management of the energy required for such heating. Indeed, the use of electric heating allows for sufficient heating with a lower energy demand than thermal heating, while also limiting CO2 emissions.
[0046] The heating process may also have one or more of the following characteristics, taken alone or in combination.
[0047] According to one embodiment, the preheating step is carried out for at least 15 min, and in particular for a duration of between 18 and 20 min.
[0048] According to one embodiment, the duration of the heating step is greater than 90 minutes.
[0049] According to one embodiment, the heating step is implemented as long as a temperature difference between the temperature measured by the first temperature sensor and the temperature measured by the second temperature sensor is greater than or equal to 2°C.
[0050] Thus, it is possible to guarantee homogeneous heating between the two tires.
[0051] According to one embodiment, the heating process includes a setting step in pressure, in which the pressure control system places the first tire and the second tire at an internal pressure such that a pressure difference between the two tires is less than 0.05 bar, and in particular less than 0.01 bar.
[0052] Thus, it is possible to guarantee good pressure homogeneity between the two tires.
[0053] Brief description of the drawings
[0054] Other aspects, objectives, advantages and features of the invention will become clearer upon reading the following detailed description of preferred embodiments thereof, given by way of non-limiting example, and made with reference to the accompanying drawings in which:
[0055] [Fig-1] Fig. 1 is a schematic view of a heating system according to a mode of a particular implementation of the invention.
[0056] [Fig.2] The [Fig.2] is a schematic view of a heating process according to a particular embodiment of the invention. Detailed description
[0057] In the figures and throughout the description, the same reference numerals represent identical or similar elements. Furthermore, the various elements are not drawn to scale in order to enhance the clarity of the figures. Moreover, the different embodiments and variations are not mutually exclusive and may be combined.
[0058] As can be seen in [Fig. 1], the invention relates to a heating system 1 for heating at least one tire PI, P2, P3, P4 to a predetermined setpoint temperature. Generally, the heating system 1 is used in motorsports, where it can be configured to heat at least two tires PI, P2, P3, P4, and in particular four tires PI, P2, P3, P4. [Fig. 1] illustrates, in particular, an embodiment in which the heating system is designed to heat two sets of four tires PI, P2, P3, P4, i.e., eight tires.
[0059] In order to obtain optimal performance on the road, the target temperature is generally chosen between 70°C and 100°C, in particular between 75°C and 85°C, and in particular substantially equal to 80°C. Such a value is not, however, limiting, and may depend on the materials constituting the tire.
[0060] The heating system 1 comprises at least one closed heating chamber 10, 12 internally delimiting an internal volume 11 for receiving said at least one tire PI, P2, P3, P4. More precisely, the internal volume 11 of the heating chamber 10, 12 can define a housing for receiving the tires PI, P2, P3, P4. Figure 1 illustrates a variant in which the heating system 1 comprises a first heating chamber 10 for receiving four tires PI, P2, P3, P4, and a second heating chamber 12 for receiving four other tires PI, P2, P3, P4. In this way, it is possible to maximize the number of tires PI, P2, P3, P4 that can be heated by the heating system 1.
[0061] The heating system 1 may further include a tire support 40 comprising a plurality of receiving platforms 41 and at least one spacer 43 separating two receiving platforms 41, each platform of the plurality of receiving platforms 41 being intended to receive a tire PI, P2, P3, P4. In this way, the storage of tires PI, P2, P3, P4 in the heating chamber 10, 12 is facilitated. Furthermore, the presence of a spacer 43 in each receiving plane 41 allows the tires PI, P2, P3, P4 to be separated to allow good air circulation, in particular when a plurality of tires PI, P2, P3, P4 are housed in the internal volume 11 of the heating chamber 10, 12. According to one embodiment, the spacers 43 can serve as support for one or more of the constituent elements of the pressure regulation system 30 which will be described later.Thus, the spacers 43 can include said pressure regulation system 30 allowing air to be added or removed during heating, while checking the pressures of tires PI, P2, P3, P4, without manipulating said tires PI, P2, P3, P4.
[0062] The heating system 1 also includes a temperature control system 20 at least partially disposed in the heating enclosure 10, 12. The temperature control system 20 includes at least one heating device 21 and at least one temperature sensor 23.
[0063] The heating device 21 is an electrically powered heating device comprising at least one electrical resistance. Figure 1 illustrates, in particular, a heating device comprising three electrical resistances per heating chamber 10, 12. For example, the electrical resistances may be 1000 W. Advantageously, the electrical resistances may be uniformly distributed over a receiving surface of the heating chamber 10, 12. The tires P1, P2, P3, P4 may then be placed above the electrical resistances in the direction of gravity. The heating device 21 is configured to heat the air contained within the internal volume 11 of the heating chamber 10, 12.
[0064] Said at least one temperature sensor 23 is configured to measure an internal temperature prevailing in the internal volume 11 of the heating chamber 10, 12, such as a thermometer. Furthermore, it is possible that at least one temperature sensor 23 includes a temperature probe configured to measure the temperature inside one of the tires PI, P2, P3, P4, and / or each tire PI, P2, P3, P4. If at least two tires PI, P2 are heated, the temperature control system 20 may include a first temperature sensor 23 for measuring the temperature inside the first tire PI, and a second temperature sensor 24 for measuring the temperature inside the second tire P2. In this way, it is possible to obtain a precise measurement of the temperature inside each of the tires PI, P2, P3, P4, and thus to control the uniformity of the heating.
[0065] Thus, the heating device 21 and the temperature sensor 23 allow the temperature control system 20 to activate the heating device 21 when the internal temperature measured by the temperature sensor 23 is strictly lower than the setpoint temperature.
[0066] According to the non-limiting variant shown in [Fig. 1], the temperature control system 20 may also include at least one fan 25, 27 configured to agitate the air contained in the internal volume 11 of the heating chamber 10, 12 in order to homogenize the internal temperature prevailing in the internal volume 11 of the heating chamber 10, 12. Thus, it is possible to influence the temperature homogeneity inside the chamber. The placement of the tires P1, P2, P3, P4 at the set temperature is therefore more reliable and precise. For example, the temperature control system 20 may include at least one upper fan 25 arranged above the housing intended to receive the tires P1, P2, P3, P4, in the direction of gravity. [Fig. 1] illustrates a variant in which each heating chamber 10, 12 includes three upper fans 25.The upper fans 25 can for example be configured to direct a flow of hot air from the rims of the tires PI, P2, P3, P4, towards the walls of the heating chamber 10, 12. .
[0067] The temperature control system 20 may also include at least one lower fan 27 arranged below the housing for receiving the tires P1, P2, P3, P4, in the direction of gravity. Figure 1 illustrates a variant in which each heating chamber 10, 12 includes two lower fans 27. Thus, the spatial distribution of the upper and lower fans 25, 27 allows for better homogenization of the internal temperature within the internal volume 11 of the heating chamber 10, 12. More specifically, said at least one lower fan 27 may be arranged on a wall adjacent to the receiving surface on which the electrical resistors 21 are located. In this way, it is possible to prevent the electrical resistors 21 from damaging the at least one lower fan 27. Advantageously, the at least one lower fan 27 may be fluidic communication with a guide duct configured to guide air towards the rims of the PI, P2, P3, P4 tires. Thus, at least one lower fan 27 can be configured to blow air horizontally and the guide duct allows a flow of hot air to be directed towards the rims, in a direction contrary to gravity.
[0068] The airflow is guided by at least one lower fan 27 towards the rims, and the airflow is guided by at least one upper fan 25 towards the walls of the heating chamber 10, 12, forming an air circulation circuit within the heating chamber 10, 12. The heating of tires PI, P2, P3, P4 is thus optimized.
[0069] The heating system 1 may advantageously include a pressure control system 30 comprising at least one valve 31 and at least one pressure sensor 33. Each valve 31 may be designed to allow or alternatively prevent the inflation of one of the tires P1, P2, P3, P4, in order to increase or decrease the inflation pressure inside said tire P1, P2, P3, P4. The pressure sensor 33 is designed to measure said inflation pressure. Thus, it is possible to adjust the pressure of the tires P1, P2, P3, P4 simultaneously with their temperature. This allows the tires P1, P2, P3, P4 to be prepared for a car race. Depending on the embodiment chosen, each valve 31 may be provided for manual operation by a user. The arrangements described above also allow the pressure of the tires P1, P2, P3, P4 to be controlled without handling them.
[0070] As can be seen in the variant shown in [Fig. 1], each tire is connected to a specific valve 31, and the entire inflation system is connected to a main valve 32. In the case where several tires PI, P2, P3, P4 are to be heated to the set temperature, it is advantageous for the pressure control system 30 to include a pressure valve 31 and a pressure sensor 33 associated with each tire PI, P2, P3, P4. In this case, a control unit 35 can be configured to receive a pressure value from each of the pressure sensors 33 and to selectively actuate each pressure valve 31 according to the pressure difference between the pressure values communicated by the pressure sensors 33, in such a way as to set a pressure difference between the two tires PI, P2, P3, P4 of less than 0.05 bar, and in particular less than 0.01 bar.It is therefore well understood that one way to homogenize the pressure between the different tires can consist either of inflating a tire with a lower internal pressure than another tire, or of deflating a tire with a higher internal pressure than the other tires, or both. Thus, it is possible to guarantee a homogeneous pressure distribution in tires PI, P2, P3, P4 before they leave the heating chamber 10, 12. The control unit 35 can therefore allow the pressure of tires PI, P2, P3, P4 to be checked automatically, without handling the tires PI, P2, P3, P4.
[0071] It is well understood that the number of heating devices, the number of temperature sensors, the number of valves 31, the number of fans 25, 27, and the number of pressure sensors 33 is not limited by the representation shown in [Fig.1], and that a person skilled in the art can modify these numbers according to the number of heating chambers 10, 12, to equip all the heating chambers 10, 12.
[0072] The set of provisions described above makes it possible to propose a heating system 1 for tires PI, P2, P3, P4 allowing efficient and precise heating of tires PI, P2, P3, P4 to a predetermined setpoint temperature while limiting energy consumption and protecting the users of the heating system 1. Indeed, the use of at least one electric resistance makes it possible to heat a set of four tires PI, P2, P3, P4 with a power of less than 2000 W.
[0073] As illustrated in [Fig.1], the invention also relates to a method of heating tires PI, P2, P3, P4 to place at least one tire PI, P2, P3, P4 at a predetermined setpoint temperature.
[0074] The heating process first includes a step of making available El a heating system 1 as described above.
[0075] The heating process then includes a preheating step E2 using electrical energy, in which the heating device 21 is activated to heat the internal volume 11 of the heating chamber 10, 12 to a temperature substantially equal to the setpoint temperature. For example, the preheating step E2 is carried out for at least 15 minutes, and in particular for a duration of between 18 and 20 minutes.
[0076] The heating process then includes an introduction step E3, in which said at least one tire PI, P2, P3, P4 is introduced into the internal volume 11 of the heating chamber 10, 12.
[0077] An electrically powered heating stage E4 is then implemented, in which the temperature control system 20 maintains the internal temperature of the internal volume 11 at a temperature substantially equal to the setpoint temperature in the internal volume 11 for a predetermined heating time. Generally, the heating time is greater than or equal to 90 minutes. The heating stage E4 can be implemented as long as the temperature difference between the temperature measured by the first temperature sensor 23 and the temperature measured by the second temperature sensor 24 is greater than or equal to 2°C. Thus, it is possible to ensure homogeneous heating between the two tires P1, P2, P3, P4. In other words, the heating device 21 can heat the air contained in the internal volume 11 as long as the pressure measured by the temperature sensor 23, 24 measures a temperature less than 2°C below the setpoint temperature.
[0078] According to one embodiment, the heating process may also include a pressurization step E5, in which the pressure control system 30 places the first tire PI and the second tire P2 at an internal pressure such that the pressure difference between the two tires PI, P2 is less than 0.05 bar, and in particular 0.01 bar. Thus, it is possible to ensure good pressure homogeneity between the two tires PI, P2, P3, P4. However, it is entirely possible to allow the tires PI, P2, P3, P4 to have different setpoint values. This pressurization step E5 can be carried out concurrently with the heating step E4. Advantageously, the heating step E4 can also be carried out as long as the pressure difference between the two tires PI, P2 is greater than 0.05 bar, and in particular greater than 0.01 bar.
[0079] The provisions described above make it possible to propose a heating method for precisely heating PI, P2, P3, and P4 tires, with efficient management of the energy required for such heating. Indeed, the use of electric heating allows for sufficient heating with a lower energy demand than thermal heating, while also limiting CO2 emissions.
