Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a brake chamber and a vehicle. Background Art

[0002] The brake chamber is a critical component in a vehicle's braking system. It features an inlet and a breathing hole. When braking, compressed air enters the chamber through the inlet, pushing the push rod inside to apply the brakes. The breathing hole balances the pressure difference between the inside and outside of the chamber.

[0003] Vehicles sometimes pass through flooded roads, such as during floods when heavy trucks carrying supplies must navigate these sections. Consequently, accumulated water and impurities can enter the brake chamber through the breathing hole, affecting braking effectiveness. A dedicated brake chamber is designed for flooding conditions. This chamber features a breathing hole at the top, connected to an air pipe that extends above the water surface to ensure proper breathing.

[0004] However, in the brake air chamber suitable for wading conditions, cold air is easily condensed into condensed water, and it is difficult to discharge the condensed water from the brake air chamber. Utility Model Content

[0005] The present application provides a brake air chamber and a vehicle, which are suitable for normal working conditions and wading conditions, and are used to solve the technical problem that it is difficult to discharge condensed water in the brake air chamber.

[0006] In one aspect, the present application provides a brake air chamber comprising a cavity and an air pipe having a connecting end and a breathing end;

[0007] A first breathing hole is opened at the upper portion of the cavity, and a second breathing hole is opened at the lower portion of the cavity;

[0008] The brake chamber has a first working mode and a second working mode;

[0009] When the brake air chamber is in the first working mode, the first breathing hole is closed and the second breathing hole is open;

[0010] When the brake air chamber is in the second working mode, the connecting end is connected to the first breathing hole, the breathing end extends to the top of the cavity, and the second breathing hole is closed.

[0011] In a possible implementation, the first breathing hole is provided at the top of the cavity.

[0012] In a possible implementation, the second breathing hole is provided at the bottom of the cavity.

[0013] In a possible implementation, the brake air chamber further includes a blocking member;

[0014] When the brake air chamber is in the first working mode, the blocking member blocks the first breathing hole to close the first breathing hole;

[0015] When the brake air chamber is in the second working mode, the blocking member blocks the second breathing hole to close the second breathing hole.

[0016] In a possible implementation, the blocking member has a threaded connection portion, and the first breathing hole and the second breathing hole are both threaded holes;

[0017] When the brake air chamber is in the first working mode, the blocking member is threadedly connected to the first breathing hole;

[0018] When the brake air chamber is in the second working mode, the blocking member is threadedly connected to the second breathing hole.

[0019] In a possible implementation, the brake air chamber further includes a first sealing ring;

[0020] When the brake air chamber is in the first working mode, the first sealing ring is sandwiched between the blocking member and the first breathing hole;

[0021] When the brake air chamber is in the second working mode, the first sealing ring is sandwiched between the blocking member and the second breathing hole.

[0025] On the other hand, the present application provides a vehicle comprising an axle and the brake chamber according to any one of the above items.

[0026] The brake chamber is mounted on the axle;

[0027] When the brake chamber is in the second working mode, the air pipe of the brake chamber is tied to the axle.

[0028] The brake chamber and vehicle provided by this application have the following beneficial effects:

[0029] The brake chamber provided herein includes a cavity and an air pipe having a connecting end and a breathing end. A first breathing hole and a second breathing hole are respectively provided in the upper and lower portions of the cavity. Under normal operating conditions, the brake chamber is set to a first operating mode. Since the first breathing hole in the upper portion is closed and the second breathing hole in the lower portion is open, the brake chamber can inhale and exhaust air through the second breathing hole. The second breathing hole's location in the lower portion of the cavity facilitates the removal of condensed water from the brake chamber.

These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0045] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0046] The related art has a technical problem with making it difficult to drain condensed water from the brake chamber. This problem arises because, despite the brake chamber's excellent airtightness, the air inside the chamber easily condenses into condensed water when the temperature drops. For example, when the brake chamber moves from land to water, the lower temperature in the water causes the temperature inside the brake chamber to drop, leading to the formation of a small amount of condensed water. Because the breather port in the related art is located at the top of the brake chamber, this condensed water is difficult to drain through the breather port.

[0047] To address the above technical issues, the present application provides a brake chamber and a vehicle. By providing a first breathing hole in the upper portion of the chamber and a second breathing hole in the lower portion of the chamber, the brake chamber can breathe through a trachea connected to the first breathing hole during wading conditions, thereby ensuring the airtightness of the brake chamber. When leaving the wading area and operating normally, the second breathing hole in the lower portion of the chamber can be used for breathing and drainage to remove any condensed water in the brake chamber.

[0048] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0049] refer to Figure 1 and Figure 2 The brake chamber provided in the embodiment of the present application includes a cavity 10 and an air pipe 20. The cavity 10 is the main structure of the brake chamber, and a first breathing hole 11 and a second breathing hole 12 are opened on the cavity 10. The first breathing hole 11 is located above the second breathing hole 12, for example, Figure 1 and Figure 2 The first breathing hole 11 is located at the upper portion of the cavity 10, and the second breathing hole 12 is located at the lower portion of the cavity 10. The first breathing hole 11 and the second breathing hole 12 are generally circular holes, but are not limited to circular holes. For example, they can also be approximately circular holes, elliptical holes, approximately elliptical holes, square holes, or approximately square holes.

[0050] like Figure 3 As shown, the air pipe 20 is a flexible structure. It has a connecting end 21 and a breathing end 22. For example, the first section and the last section of the air pipe 20 are the connecting end 21 and the breathing end 22, respectively. When the vehicle is in wading conditions, the air pipe 20 is used to breathe the brake chamber. In this case, the connecting end 22 is connected to the first breathing hole 11 of the cavity 10, and the breathing end 22 extends above the cavity 10. When the vehicle is in normal operation, the air pipe 20 can be tied to the cavity 10 or stored inside the vehicle.

[0051] The brake chamber has a first operating mode and a second operating mode. The first operating mode is when the vehicle is in normal operating conditions, which refers to the vehicle operating in non-water-wading conditions. The second operating mode is when the vehicle is in water-wading conditions, which refers to the vehicle operating in a water-wading situation, for example, when part of the brake chamber is submerged in water.

[0052] When the brake chamber is in the first working mode, refer to Figure 1 The first breathing hole 11 is closed, for example, blocked. The second breathing hole 12 is open, connecting the inside and outside of the brake air chamber, allowing the brake air chamber to breathe in and out through the second breathing hole 12. Since the second breathing hole 12 is located at the bottom of the cavity 10, it can easily discharge condensed water and impurities that may be present in the brake air chamber.

[0053] When the brake chamber is in the second working mode, refer to Figure 2 The second breathing hole 12 is closed, for example, by being blocked. The connection end 21 of the air pipe 20 is connected to the first breathing hole 11, and the breathing end 22 extends above the cavity 10. For example, the breathing end 22 is tied to the axle of the vehicle so that the breathing end 22 is above the water surface. At this time, the brake air chamber exhales and inhales through the air pipe 20, preventing water from entering the air pipe.

[0054] Furthermore, since the first breathing hole 11 is located at the upper part of the cavity 10 , the connection end 21 of the air pipe 20 is kept away from the bottom of the water, thereby preventing the air pipe 20 from being damaged by stones, debris, etc. on the bottom of the water.

[0055] When the vehicle leaves the wading area and is in normal operating conditions, the second breathing hole located at the lower part of the cavity 10 can be opened to discharge condensed water that may exist in the brake air chamber.

[0056] When the brake chamber provided in the embodiment of the present application is in a water-wading condition, breathing can be performed through the air pipe 20 connected to the first breathing hole 11 to ensure the airtightness of the brake chamber. When the vehicle leaves the water-wading area and enters normal operation, breathing and drainage can be performed through the second breathing hole 12 located at the lower portion of the cavity 10 to remove any condensed water in the brake chamber.

[0057] In some embodiments, as shown in the figure, the first breathing hole 11 is provided at the top of the cavity 10, and the first breathing hole 11 is located at the topmost end of the cavity 10. Such a configuration facilitates the connection between the trachea 20 and the cavity 10.

[0058] In some embodiments, the second breathing hole 12 is provided at the bottom of the cavity 10, and the second breathing hole 12 is located at the bottom end of the cavity 10. This arrangement facilitates complete discharge of condensed water in the cavity 10.

[0059] In some embodiments, as Figure 1 The brake chamber also includes a sealing member 30. This member is used to seal the first or second breathing hole 11, 12. The sealing member 30 is slightly larger than the inner diameter of the first or second breathing hole 11, 12, creating an interference fit between the sealing member 30 and the first breathing hole 12, ensuring that the first or second breathing hole 11, 12 is sealed.

[0060] When the brake chamber is in the first operating mode, the blocking member 30 blocks the first breathing hole 11, thereby sealing the first breathing hole 11 and allowing the brake chamber to inhale and exhaust air through the second breathing hole 12. When the brake chamber is in the second operating mode, the blocking member 30 blocks the second breathing hole 12, thereby sealing the second breathing hole 12 and preventing water from entering the second breathing hole 12.

[0061] In some embodiments, as Figure 4 As shown, the blocking member 30 has a threaded connection portion 31. For example, the blocking member 30 is a screw, and the bolt includes a screw head and a screw, and the threaded connection portion 31 is located on the screw. The first breathing hole 11 and the second breathing hole 12 are both threaded holes.

[0062] When the brake chamber is in the first operating mode, the threaded connection portion 31 of the blocking member 30 is threadedly connected to the threaded hole of the first breathing hole 11. Threading the blocking member 30 to the first breathing hole 11 facilitates installation. Compared to directly blocking the first breathing hole 11 with the blocking member 30, the threaded connection provides greater connection strength and reliability.

[0063] When the brake chamber is in the second operating mode, the threaded connection portion 31 of the blocking member 30 is threadedly connected to the second breathing hole 12. This threaded connection facilitates installation. Compared to directly blocking the second breathing hole 12 with the blocking member 30, the threaded connection provides greater connection strength and reliability.

[0064] In some embodiments, the brake chamber further includes a first sealing ring. The first sealing ring is used to seal the connection between the sealing member 30 and the first breathing hole 11 or the connection between the sealing member 30 and the second breathing hole 12. The first sealing ring may be a rubber ring.

[0065] When the brake air chamber is in the first working mode, the first sealing ring is clamped between the sealing member 30 and the first breathing hole 11. For example, after the first sealing ring is sleeved on the threaded connection portion 31 of the sealing member 30, the sealing member 30 is threadedly connected to the first breathing hole 11, thereby improving the airtightness of the connection between the sealing member 30 and the first breathing hole 11.

[0066] When the brake chamber is in the second operating mode, the first sealing ring is sandwiched between the blocking member 30 and the second breathing hole 12. For example, the first sealing ring is placed on the threaded connection portion 31 of the blocking member 30, and then the blocking member 30 is threadedly connected to the second breathing hole 12, thereby improving the airtightness of the connection between the blocking member 30 and the second breathing hole 12.

[0067] In some embodiments, the connection end 21 of the air tube 20 includes a hollow screw portion 211. The screw portion 211 can be bonded or riveted to the main body of the air tube 20. When the brake chamber is in the second operating mode, the screw portion 211 is threadedly connected to the first breathing hole 11. Compared to directly inserting the air tube 20 into the first breathing hole 11, the threaded connection provides greater stability, reliability, and strength.

[0068] Based on the above embodiment, the brake chamber further includes a second sealing ring. When the brake chamber is in the second operating mode, the second sealing ring is sandwiched between the screw portion 211 and the first breathing hole 11. For example, the second sealing ring is sleeved onto the screw portion 211, and the screw portion 211 is then threadedly connected to the first breathing hole 11, thereby improving the airtightness of the connection between the screw portion 211 and the first breathing hole 11.

[0069] In some embodiments, the brake air chamber further includes a filter screen installed at the breathing end 22. The filter screen is used to filter out external impurities to prevent external impurities from entering the cavity 10 through the trachea 20, thereby preventing the external impurities from affecting the normal operation of the brake air chamber.

[0070] This application also provides a vehicle comprising an axle and a brake chamber. The brake chamber is mounted on the axle. When the brake chamber is in the second operating mode, the brake chamber's air pipe 20 is tied to the axle. The specific structure and connection method of the brake chamber can be found in any of the aforementioned embodiments.
