[0001] The present invention relates to the technical field of vehicle manufacturing, and particularly to a brake disc, a braking device, a temperature regulation method and a vehicle. Background Art

[0002] The braking device is one of the important components of a vehicle and is directly related to life and property safety. Among them, disc brakes are widely used in various vehicles due to their stable braking performance and good heat dissipation.

[0003] During the braking process of a vehicle, a large amount of heat is generated due to friction between the brake disc and the brake pads. Over time, the braking-related components will prematurely degrade and even fail, seriously affecting the driving safety of the whole vehicle. In addition, when parking for a period of time in a low-temperature rain and snow environment, the brake disc and the brake pads will freeze due to the accumulated water on the brake disc, resulting in the failure to release the handbrake and the vehicle being unable to quickly return to the normal driving state.

[0004] Therefore, there is an urgent need to solve the problem that the disc brake in the prior art is easily affected by high or low temperature working environments, thereby affecting the normal driving state of the vehicle. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a brake disc, a braking device, a temperature regulation method and a vehicle to solve the problems mentioned in the prior art.

[0016] Further, the connecting part includes: a first annular part fixedly connected with the driving shaft, and a second annular part sleeved on the first annular part, and the second annular part is rotatably connected with the first annular part.

[0017] In addition, the present application also provides a temperature regulation method for a braking device, including the following steps:

[0046] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to specific embodiments and the accompanying drawings.

[0047] It should be noted that unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present invention should have the ordinary meanings understood by those of ordinary skill in the art to which the present disclosure belongs.

The terms such as "upper", "lower", "left", "right" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0048] In one or more embodiments of the present application, a brake disc 1 is provided. Here, the brake disc 1 is generally applied to a disc brake. The brake disc 1 rotates synchronously with the wheel, and a friction element (such as a brake pad) clamps the brake disc 1 from both sides to generate a braking effect. At present, there are various structural forms of friction elements, such as caliper disc type or full disc type, etc. Here, the brake disc 1 can be applied to various structural forms of different disc brakes.

[0049] As Figure 1 and Figure 2 shown, in this embodiment, a brake disc 1 is provided. The brake disc 1 has a cavity 12 inside. The brake disc 1 has a perforation for connecting to a drive shaft 2. An inlet 13 and an outlet 14 communicating with the cavity 12 are provided on the inner wall surface of the perforation corresponding to the drive shaft 2.

[0050] From the above description, it can be seen that for the brake disc 1 provided in this embodiment, by providing a cavity 12 inside the brake disc 1, liquid can circulate in the cavity 12 through the inlet 13 and the outlet 14, so as to perform circulating liquid cooling or heating operations on the inside of the brake disc 1. Thus, the brake disc 1 can avoid problems such as reduced service life due to high-temperature friction or freezing with the friction block 5 due to low temperature and inability to start, which is beneficial to maintaining a good working state in high-temperature or low-temperature environments; in addition, since the circulating liquid is poured into the inside of the brake disc 1 for heating or cooling, compared with the scheme of directly spraying liquid on the surface of the brake disc 1, waste can be reduced, and the influence of liquid residue on the subsequent working state of the brake disc 1 can be avoided.

[0051] In some embodiments, a plurality of axially penetrating air holes 11 are provided on the brake disc 1. The provision of the air holes 11 can ventilate and dissipate heat or heat the brake disc 1, and the provision of the air holes can further enhance the cooling or heating rate of the brake disc 1.

[0052] In some embodiments, the air holes 11 are arranged in a pairwise centrosymmetric manner on the brake disc 1. The connection line of the air holes 11 of the same size is a square or a circle coaxial with the brake disc 1. This setting can ensure that the brake disc 1 is subjected to a uniform centrifugal force when rotating at high speed.

[0053] In some embodiments, the inlet 13 and the outlet 14 on the brake disc 1 are arranged oppositely. The oppositely arranged inlet 13 and outlet 14 can make the liquid stay in the cavity 12 for as long as possible, so that the brake disc 1 can receive the heating or cooling effect of the liquid faster.

[0054] The present application also provides a braking device, as Figure 1 and Figure 3As shown, it includes the brake disc 1 described in any of the above embodiments, and also includes a ventilation mechanism, a drive shaft 2, and a liquid circulation mechanism. Here, there should also be other installation components in the braking device to enable the normal operation of the brake disc 1. The liquid in the liquid circulation mechanism can be various liquid media such as water or coolant, which will not be elaborated in this embodiment.

[0055] Still as Figure 1 shown, in the braking device of this embodiment, the ventilation mechanism is configured to supply air to at least one air hole 11 on the brake disc 1; the drive shaft 2 penetrates through the perforation and is connected to the brake disc 1; the liquid circulation mechanism is sleeved on the drive shaft 2, and the drive shaft 2 is provided with a first channel 21 and a second channel 22 whose one ends are respectively communicated with the liquid circulation mechanism. The other end of the first channel 21 is communicated with the liquid inlet 13, and the other end of the second channel 22 is communicated with the liquid outlet 14.

[0056] In some embodiments, the ventilation mechanism includes an air-conditioning system for supplying air and a housing 3 communicating with the air-conditioning system. The housing 3 is arranged to cover a part of the surface of the brake disc 1. Here, the air-conditioning system can share the same equipment with the air-conditioning system inside the vehicle. The air-conditioning system is connected to the housing 3 through an external pipeline for conveying, so as to realize the air supply to the brake disc 1.

[0057] Furthermore, as Figure 3 shown, the aforementioned housing 3 is a sector-shaped housing 3. The housing 3 is provided with a connection port 31 for connecting the external pipeline of the air-conditioning system. The diameter of the connection port 31 is set smaller than the covering area of the sector-shaped housing 3. When the air-conditioning system supplies air through the connection port 31, since the brake disc 1 rotates synchronously with the wheel, the air holes 11 of the brake disc 1 will sequentially pass through the covering area of the housing 3 corresponding to the brake disc 1. Under the external pressure, the air volume can blow the entire covering area inside the sector-shaped housing 3, so that the air of the air-conditioning system can pass through the air holes 11 located in this covering area.

[0058] As an alternative implementation manner, the housing 3 can also be set in other forms, such as rectangular or circular, but the covering area of the housing 3 should be at least larger than the diameter of any air hole 11 on the brake disc 1 to ensure the air supply effect of the ventilation mechanism on the brake disc 1.

[0059] In some embodiments, the air volume of the air-conditioning system is pressurized by a gas booster pump 33 and then conveyed into the housing 3. The air-conditioning system and the gas booster pump 33 are connected through a first regulating valve 32. The first regulating valve 32 is an air valve with adjustable opening. By setting the air valve, the air supply size of the ventilation mechanism to the brake disc 1 can be flexibly adjusted, which is beneficial for the brake disc 1 to adapt to different working environments.

[0060] For example, when it is necessary to quickly cool the brake disc 1 by air or thaw it by hot air, the first regulating valve 32 is fully opened at 100% power for operation; when considering energy conservation or normal heat dissipation during cruising, the opening of the first regulating valve 32 can be set to 50% for normal operation. Here, the opening control of the first regulating valve 32 can be reflected on the function selection module at the driver's seat. This function selection module can be set in the glove box, instrument panel, steering wheel, etc., so as to facilitate the driver to control the ventilation mechanism; as an alternative implementation, the first regulating valve 32 can also directly replace manual control through the vehicle machine control system, for example, using the vehicle ECU (Electronic Control Unit) to control.

[0061] In some embodiments, the drive shaft 2 is used to drive the wheel to rotate. The wheel is coaxially connected to the brake disc 1. The brake disc 1 is fixed on the wheel and rotates synchronously with the wheel. The drive shaft 2 and the brake disc 1 can be fixedly connected by key fit or bolt fit. Here, in addition to the above connection method, the drive shaft 2 and the brake disc 1 can also be connected by other existing connection methods.

[0062] On this basis, two non-communicating first channels 21 and second channels 22 are provided inside the drive shaft 2. The first channels 21 and the second channels 22 are arranged along the axis of the drive shaft 2. When the drive shaft 2 is fixedly connected to the brake disc 1, one end of the first channel 21 close to the brake disc 1 is communicated with the liquid inlet 13 of the brake disc 1, and one end of the second channel 22 close to the brake disc 1 is communicated with the liquid outlet 14 of the brake disc 1.

[0063] It should be noted that in order to reduce the influence of the set channels on the strength of the drive shaft 2, the first channels 21 and the second channels 22 can be selected as strip channels; since the liquid inlet 13 and the liquid outlet 14 are oppositely arranged on the perforation of the brake disc 1, the first channels 21 and the second channels 22 only need to be oppositely arranged on the drive shaft 2. As an alternative implementation, the first channels 21 and the second channels 22 can also be set in other forms, for example, the cross-section of the channels is a sector arranged along the arc surface of the drive shaft 2.

[0064] In some embodiments, the aforementioned liquid circulation mechanism includes a liquid inlet pipe 41, a liquid outlet pipe 42 and a connecting part. Among them, the liquid inlet pipe 41 and the liquid outlet pipe 42 are respectively communicated with the water circuit of the vehicle body structure. The water circuit of the vehicle body structure can adopt existing mature water connection methods, and this embodiment does not make an absolute limitation on this.

[0065] Here, it should be noted that the liquid circulation mechanism can be used to heat or cool the brake disc 1. Therefore, the following scenarios may exist: the liquid inlet pipe 41 inlet coolant, and the liquid outlet pipe 42 outlet hot liquid carrying the heat of the brake disc 1; the liquid inlet pipe 41 inlet hot liquid, and the liquid outlet pipe 42 outlet cold liquid after heat dissipation.

[0066] Further, the liquid in the water circuit of the vehicle body structure enters the liquid inlet pipe 41 after being pressurized by a pressure pump 49. The water circuit and the pressure pump 49 are connected by a second regulating valve 48. The second regulating valve 48 is a liquid valve with adjustable opening. By setting the liquid valve, the liquid supply speed of the water circuit to the brake disc 1 can be flexibly adjusted, which is beneficial for the brake disc 1 to adapt to different working environments.

[0067] For example, when it is necessary to quickly perform liquid cooling and heat dissipation or heating and thawing on the brake disc 1, the second regulating valve 48 operates at 100% full power with an opening degree; when considering energy conservation or normal heat dissipation during cruising, the opening degree of the second regulating valve 48 can be set to 50% for normal operation. Here, the opening degree control of the second regulating valve 48 can be reflected on the function selection module at the driver's seat. The function selection module can be set in the glove box, instrument panel, steering wheel, etc., so as to facilitate the driver to control the ventilation mechanism; in addition, the second regulating valve 48 can also directly replace manual control through the vehicle-mounted control system, such as using the vehicle ECU (Electronic Control Unit) for control.

[0068] In some embodiments, as Figure 4 shown, the connecting part is rotatably and sealingly sleeved with the drive shaft 2. A first annular cavity 43 and a second annular cavity 44 are formed and separated between the connecting part and the drive shaft 2. Among them, the liquid inlet pipe 41 communicates with the first channel 21 through the first annular cavity 43, and the liquid outlet pipe 42 communicates with the second channel 22 through the second annular cavity 44.

[0069] In the above embodiment, the connecting part includes a first annular part 45 fixedly connected to the drive shaft 2, and a second annular part 46 sleeved on the first annular part 45. The second annular part 46 is rotatably connected to the first annular part 45.

[0070] As Figures 4 to 6 shown, the first annular part 45 is provided with openings for the first channel 21 and the second channel 22 to pass through. The first annular part 45 and the drive shaft 2 are fixedly connected by screwing or other means. Along the axial direction of the drive shaft 2, a first sealing member 50, a second sealing member 51, and a third sealing member 52 are sequentially and spacedly provided between the first annular part 45 and the second annular part 46. Among them, the first annular cavity 43 is formed between the first sealing member 50 and the second sealing member 51, and the second annular cavity 44 is formed between the second sealing member 51 and the third sealing member 52. Thus, the first annular cavity 43 and the second annular cavity 44 are jointly formed by the partial surfaces of the first annular part 45, the second annular part 46, and the drive shaft 2, avoiding affecting the normal liquid circulation channel.

[0071] Here, setting the seal can further improve the sealing performance of each annular cavity, thus avoiding liquid leakage and affecting the use effect; the first seal 50, the second seal 51 and the third seal 52 can be arranged between the first annular part 45 and the second annular part 46 in the form of oil pressure sealing. As an alternative implementation, more seals can also be arranged between the first annular part 45 and the second annular part 46, as long as the first annular cavity 43 and the second annular cavity 44 are separated from each other.

[0072] In some embodiments, the first annular part 45 and the second annular part 46 can be sleeved and connected by snap connection. Among them, an installation cavity is also formed between the first annular part 45 and the second annular part 46. A limiting step is arranged on the first annular part 45 or the second annular part 46. The installation cavity is the space formed by the limiting step giving way after the first annular part 45 and the second annular part 46 are butted. A plurality of balls 47 are filled in the installation cavity. This setting can reduce the rotational friction force of the second annular part 46 relative to the first annular part 45, making the relative movement between the two smoother. As an alternative implementation, an installation cavity can be arranged at both ends of the first annular part 45 and the second annular part 46 respectively, and balls 47 are filled in each installation cavity to further improve the smoothness effect.

[0073] As Figure 7 shown, the working states of the ventilation mechanism and the liquid circulation mechanism include the following scenarios:

[0074] (1), The first regulating valve 32 is opened, the second regulating valve 48 is closed, and the ventilation mechanism sends cold air to the brake disc 1 (A - B - C);

[0075] (2), The first regulating valve 32 is opened, the second regulating valve 48 is closed, and the ventilation mechanism sends hot air to the brake disc 1 (D - B - C);

[0076] (3), The first regulating valve 32 is closed, the second regulating valve 48 is opened, and the liquid circulation mechanism sends coolant to the brake disc 1 (E - F - G);

[0077] (4), The first regulating valve 32 is closed, the second regulating valve 48 is opened, and the liquid circulation mechanism sends heated liquid to the brake disc 1 (H - F - G).

[0078] In some embodiments, the ventilation mechanism and the liquid circulation mechanism can be used separately or in combination. The driver can flexibly select according to the actual driving scenario. For example, in hot summer or cold winter, the ventilation mechanism and the liquid circulation mechanism can be combined to perform heat dissipation or heating work on the brake disc 1 under the corresponding working environment; in spring and autumn, only the ventilation mechanism or only the liquid circulation mechanism can be used to dissipate heat from the brake disc 1.

[0079] The present application also provides a temperature regulation method for a braking device, as Figure 8 shown, which includes the following steps:

[0080] S1. Obtain ambient temperature information;

[0081] S2. Determine a temperature regulation mode according to the ambient temperature information, and send a temperature regulation signal to the ventilation mechanism so that the ventilation mechanism sends hot air or cold air to the brake disc; and / or,

[0082] Determine a temperature regulation mode according to the ambient temperature information, and send a temperature regulation signal to the liquid circulation mechanism so that the liquid circulation mechanism sends heated liquid or coolant to the brake disc.

[0083] In the above steps, in step S1, the obtained ambient temperature information can be the temperature on the surface of the brake disc, which is obtained by a temperature sensor arranged on the surface of the brake disc; as an alternative implementation manner, the temperature information can also be the temperature of the environment where the vehicle is located, which is obtained by a temperature sensor arranged on the vehicle. The manner of obtaining the ambient temperature information can be real-time acquisition or fixed-frequency periodic acquisition.

[0084] In some embodiments, the above temperature regulation method can be controlled and executed by a vehicle ECU (Electronic Control Unit); the braking device can adopt the braking device described in the above embodiments.

[0085] In some embodiments, in step S2, the determining a temperature regulation mode according to the ambient temperature information and sending a temperature regulation signal to the ventilation mechanism so that the ventilation mechanism sends hot air or cold air to the brake disc includes:

[0086] S2a. In response to the ambient temperature information being higher than a first preset threshold, determine that the temperature regulation mode is a refrigeration mode, and send a refrigeration temperature regulation signal to the ventilation mechanism so that the ventilation mechanism sends cold air to the brake disc; or,

[0087] S2b. In response to the ambient temperature information being lower than a second preset threshold, determine that the temperature regulation mode is a heating mode, and send a heating temperature regulation signal to the ventilation mechanism so that the ventilation mechanism sends hot air to the brake disc.

[0088] In the above description, an exemplary case where only the ventilation mechanism is turned on and the liquid circulation mechanism is not turned on is described. When the obtained ambient temperature information is higher than 40°C, it is determined that the temperature regulation mode is a cooling mode, and a refrigeration temperature regulation signal is sent to the ventilation mechanism so that the ventilation mechanism sends cold air to the brake disc. Here, 40°C is the first preset threshold in step S22;

[0089] Similarly, when the obtained ambient temperature information is lower than 0°C, the temperature adjustment mode is determined to be the heating mode, and a temperature adjustment signal for heating is sent to the ventilation mechanism, so that the ventilation mechanism sends hot air to the brake disc. Here, 0°C is the second preset threshold in step S22.

[0090] In some embodiments, in step S2, the determining the temperature adjustment mode according to the ambient temperature information and sending a temperature adjustment signal to the liquid circulation mechanism, so that the liquid circulation mechanism sends heated liquid or coolant to the brake disc includes:

[0091] S2c. In response to the ambient temperature information being higher than the third preset threshold, the temperature adjustment mode is determined to be the cooling mode, and a temperature adjustment signal for cooling is sent to the liquid circulation mechanism, so that the liquid circulation mechanism sends coolant to the brake disc; or,

[0092] S2d. In response to the ambient temperature information being lower than the fourth preset threshold, the temperature adjustment mode is determined to be the heating mode, and a temperature adjustment signal for heating is sent to the liquid circulation mechanism, so that the liquid circulation mechanism sends heated liquid to the brake disc.

[0093] In the above description, an exemplary situation where only the liquid circulation mechanism is turned on and the ventilation mechanism is not turned on is described. When the obtained ambient temperature information is higher than 50°C, the temperature adjustment mode is determined to be the cooling mode, and a temperature adjustment signal for cooling is sent to the liquid circulation mechanism, so that the liquid circulation mechanism sends coolant to the brake disc. Here, 40°C is the third preset threshold in step S2c;

[0094] Similarly, when the obtained ambient temperature information is lower than -10°C, the temperature adjustment mode is determined to be the heating mode, and a temperature adjustment signal for heating is sent to the liquid circulation mechanism, so that the liquid circulation mechanism sends heated liquid to the brake disc. Here, 0°C is the fourth preset threshold in step S2d.

[0095] It should be noted that the specific set values of the foregoing first preset threshold, second preset threshold, third preset threshold, and fourth preset threshold should be set according to various factors such as the vehicle condition environment and the season to which it belongs. Only examples are given in this embodiment; when the ventilation mechanism and the liquid circulation mechanism work simultaneously, as long as the ambient temperature information exceeds the corresponding preset threshold, the temperature adjustment mode can be adjusted.

[0096] In order to distinguish the working states of the ventilation mechanism and the liquid circulation mechanism, in some embodiments, the first preset threshold is lower than the third preset threshold, and the second preset threshold is higher than the fourth preset threshold. That is to say, the ventilation mechanism will first change with the ambient temperature information. When the brake disc is still in a high temperature or low temperature state after the ventilation mechanism works, the liquid circulation mechanism will work. This setting can reduce the output power as much as possible on the premise of maintaining the good working state of the brake disc, which is beneficial to saving vehicle energy. Of course, only an example is given in this embodiment. The ventilation mechanism and the liquid circulation mechanism can also work simultaneously, or the liquid circulation mechanism works first and the ventilation mechanism works later.

[0097] In addition, the present application also provides an adjustment device applicable to execute the temperature adjustment method in any of the above embodiments, as Figure 9 shown, including:

[0098] A temperature sensing module 6, configured to obtain ambient temperature information;

[0099] A first control module 7, configured to determine a temperature adjustment mode according to the ambient temperature information, and send a temperature adjustment signal to the ventilation mechanism, so that the ventilation mechanism sends hot air or cold air to the brake disc; and / or,

[0100] A second control module 8, configured to determine a temperature adjustment mode according to the ambient temperature information, and send a temperature adjustment signal to the liquid circulation mechanism, so that the liquid circulation mechanism sends heated liquid or cooling liquid to the brake disc.

[0101] For the convenience of description, the above device is described by dividing it into various modules according to functions. Of course, when implementing the present application, the functions of each module can be implemented in the same or multiple software and / or hardware.

[0102] In some embodiments, the temperature sensing module 6 is configured to detect the temperature of the surface of the brake disc or the ambient temperature of the vehicle.

[0103] In some embodiments, the first control module 7, the second control module 8 are electrically communicatively connected to the temperature sensing module 6. After receiving the ambient temperature information, the control module compares the ambient temperature information with the foregoing preset thresholds, and determines the temperature adjustment mode according to the comparison result. As an alternative implementation, the first control module and the second control module can be integrated into the same control module as long as the relevant functions can be realized.

[0104] Here, the aforementioned preset thresholds are generally: the first preset threshold and the second preset threshold for determining the air supply temperature of the ventilation mechanism. When the ambient temperature information is higher than the first preset threshold, the ventilation mechanism supplies cold air; when the ambient temperature information is lower than the second preset threshold, the ventilation mechanism supplies hot air; and the third preset threshold and the fourth preset threshold for determining the liquid supply temperature of the liquid circulation mechanism. When the ambient temperature information is higher than the third preset threshold, the liquid circulation mechanism supplies coolant; when the ambient temperature information is lower than the fourth preset threshold, the liquid circulation mechanism supplies heated liquid.

[0105] It should be noted that the specific set values of the aforementioned first preset threshold, second preset threshold, third preset threshold, and fourth preset threshold should be set according to various factors such as the vehicle condition environment and the season to which it belongs. Only examples are given in this embodiment; when the ventilation mechanism and the liquid circulation mechanism work simultaneously, as long as the ambient temperature information exceeds the corresponding preset threshold, the adjustment of the temperature control mode can be carried out.

[0106] In order to distinguish the working states of the ventilation mechanism and the liquid circulation mechanism, in some embodiments, the first preset threshold is lower than the third preset threshold, and the second preset threshold is higher than the fourth preset threshold. That is to say, the ventilation mechanism will change first with the ambient temperature information. When the brake disc is still in a high temperature or low temperature state after the ventilation mechanism works, the liquid circulation mechanism will work. This setting can reduce the output power as much as possible on the premise of maintaining the good working state of the brake disc, which is beneficial to saving vehicle energy; of course, only examples are given for the numerical settings of each preset threshold in this embodiment. The ventilation mechanism and the liquid circulation mechanism can also work simultaneously, or the liquid circulation mechanism works first and the ventilation mechanism works later.
