Description

Technical Field

[0001] This application relates to the field of separator technology, and more specifically, to automotive separators, vehicle braking systems, and vehicles. Background Technology

[0002] The vehicle braking system is a component of a vehicle, primarily used to provide braking force to force a vehicle to decelerate or stop while in motion, to smoothly park a stopped vehicle under various road conditions, or to maintain a stable speed while driving downhill. Generally, vehicle braking systems use fluids such as hydraulic oil or gas as their working medium. By appropriately adjusting the working state of these fluids (such as pressure and flow rate), the vehicle braking system can be controlled to provide the desired braking force. Utility Model Content

[0004] First, according to a first aspect of this application, a vehicle separator is provided, the vehicle separator being configured for use in a vehicle braking system, comprising:

[0005] A housing having a cavity and an opening, an inlet, and an outlet communicating with the cavity;

[0006] An impeller assembly, arranged within the cavity, is used to separate target material contained in the airflow entering the cavity from the inlet; and

[0007] A cover, which is mounted on the housing and closes the opening, has a receiving portion on the side of the cover facing the impeller assembly, the receiving portion being configured to collect the separated target material.

[0008] In the vehicle separator according to this application, optionally, the receiving portion has a first portion and a second portion, the first portion facing the impeller assembly and configured in a funnel shape, the funnel shape having a gradually narrowing cross-section in the direction from the first portion toward the second portion, the second portion facing the opening and having a channel configured to communicate between the first portion and the outside of the housing; and / or

[0009] A first sealing element, including an O-ring, is provided between the cover and the housing.

[0010] Optionally, in the vehicle separator according to this application, the vehicle separator further includes a sealing member configured to be detachably mounted on the cover and to close the passage.

[0011] In the vehicle separator according to this application, optionally, a second sealing element is provided between the sealing element and the cover element to form an end face sealing fit, the second sealing element including an O-ring.

[0012] Optionally, in the vehicle separator according to this application, the vehicle separator further includes a filter disposed in the cover and arranged in the cavity after the cover is installed in place for filtering separated target objects, including water and particulate matter, wherein the filter is configured to store particulate matter filtered by the filter, and the containment is configured to collect water filtered by the filter.

[0013] Optionally, in the vehicle separator according to this application, the impeller assembly includes:

[0014] A bracket, disposed between the inlet and the outlet, is fixed relative to the housing, with one end of the bracket's outer edge abutting the inner wall of the housing circumferentially, and the other end's outer edge spaced a predetermined distance from the inner wall of the housing; and

[0015] An impeller is fixed to the support, and the blades of the impeller are arranged at a preset angle to guide the airflow passing through the impeller and separate the target object from it. The middle part of the impeller is connected to the middle part of the support and defines a flow channel for the airflow to the outlet.

[0016] In the vehicle separator according to this application, optionally, the bracket includes a first bracket and a second bracket, the first bracket is arranged on a first side of the impeller and the outer edge of the first bracket abuts against the inner wall of the housing in the circumferential direction, the second bracket is arranged on a second side of the impeller and adjacent to the cover, the outer edge of the second bracket is spaced apart from the inner wall of the housing by the preset distance, and the impeller is interference-fitted with both the first bracket and the second bracket.

[0017] Secondly, according to a second aspect of this application, a vehicle braking system is also provided, comprising:

[0018] Working components, configured to regulate the airflow used for pneumatic braking in the vehicle braking system; and

[0019] As described in any of the above, the vehicle separator's outlet is connected to the working component to deliver the airflow thereto.

[0026] Figure 4 This is a cross-sectional structural schematic diagram of another embodiment of a vehicle separator according to this application. Detailed Implementation

[0027] It should be noted that the following descriptions, by way of example, illustrate the structural configuration, features, and advantages of the vehicle separator, vehicle braking system, and vehicle according to this application; however, all descriptions should not be construed as limiting the scope of this application. In this document, the technical terms "first" and "second" are used only for distinguishing purposes and are not intended to indicate their order or relative importance. For the sake of simplicity in the drawings, identical or similar parts and features may be indicated in only one or more places in the same drawing.

[0028] refer to Figure 1 , Figure 2 and Figure 3The above figures roughly illustrate the structure of an embodiment of the vehicle separator of this application. This vehicle separator embodiment can be configured and applied to a vehicle braking system, such as an electronic braking system (EBS), to separate and remove or reduce target objects (such as water, particulate matter, etc.) contained in the airflow used for pneumatic braking before supplying it to the working components (such as brake valve modules) in the vehicle braking system. It can also be installed between the valve and the brake drum to filter out particles generated by friction of the friction pads during the exhaust process. This can avoid or reduce the failure of the working components that would lead to a decrease or failure in braking ability, ensuring that the vehicle has good braking performance, and also help to extend the service life of the working components.

[0029] Specifically, such as Figures 1 to 3 As shown, the vehicle separator 100 may include a housing 11, an impeller assembly 12, and a cover 13. The housing 11 may be made of a suitable material (such as aluminum, aluminum alloy, etc.) and constructed with a suitable shape and size, and may be configured to have a cavity 111, an opening 112, an inlet 113, and an outlet 114.

[0030] The opening 112 communicates with the cavity 111, and can be positioned at any suitable location on the housing 11, such as at one end of the housing 11. A cover 13 can be configured to close the opening 112. The cover 13 and the housing 11 can optionally be detachably assembled together, for example, via one or more connectors 18 (such as bolts, screws, etc.). Figure 2 and Figure 3 The example demonstrates the simultaneous use of four connectors 18 to detachably mount the cover 13 onto the housing 11. When assembling the vehicle separator 100, components such as the impeller assembly 12 can be easily and detachably mounted into the cavity 111 of the housing 11 via the opening 112; similarly, in cases requiring maintenance or replacement of components, the cover 13 can be removed from the housing 11 first, and then the corresponding components arranged in the cavity 111 can be retrieved via the opening 112.

[0031] Both inlet 113 and outlet 114 are connected to cavity 111, and can be used as follows: Figure 2They are arranged on the left and right sides of the impeller assembly 12, as shown. Airflow from outside the vehicle separator 100, such as airflow from a front-end component located before the vehicle separator 100 on the vehicle, can enter the cavity 111 through the inlet 113. Then, the impeller assembly 12 can separate the target objects contained in the airflow. The target objects may include, for example, water and / or particulate matter. The presence of such target objects is generally detrimental to the operation of the working components in the vehicle braking system. The specific target objects can be determined according to the actual application requirements.

[0032] Taking valves, commonly found in vehicle braking systems, as an example, the vehicle separator described in this application is not used in the prior art. These valves are prone to malfunction after prolonged operation due to water and / or particulate matter entrained in the airflow. For instance, valves may freeze due to moisture at low temperatures, become clogged due to particulate matter accumulation, or experience delayed braking response, leading to abnormal operation or failure of the vehicle braking system. In contrast, when the vehicle separator described in this application is used, such substances can be separated from the airflow beforehand and removed or effectively reduced. This prevents or reduces their entry into valves and other working components of the vehicle braking system, ensuring the reliability of braking operation and extending the service life of the working components, thus reducing system operating costs.

[0033] To illustrate further, current EBS systems typically employ dryer tanks, which work in conjunction with corresponding valve modules to filter water and particles. However, these dryer tanks require periodic replacement; otherwise, their functionality will degrade or even fail. Due to various reasons, in practical applications, installed dryer tanks are often used for extended periods without timely replacement, making it difficult to avoid problems such as those caused by water and particles affecting the brake valve module, as mentioned earlier. The solution presented in this application effectively addresses these practical problems, bringing positive and beneficial technical effects.

[0034] As an optional configuration scenario, refer to Figures 1 to 3For example, the impeller assembly 12 can be configured to have an impeller 120, a first bracket 121 and a second bracket 122. The first bracket 121 and the second bracket 122 can be arranged on the upper and lower sides of the impeller 120 respectively, such that the outer edge of the first bracket 121 abuts against the inner wall 110 of the housing 11 in the circumferential direction, and the outer edge of the second bracket 122 is spaced apart from the inner wall 110 of the housing 11 by a preset distance (the specific value can be set as needed). The impeller 120 and the above two brackets can be assembled and connected together by a suitable connection method such as interference fit, and the middle part of the impeller 120 and the middle parts of the first bracket 121 and the second bracket 122 are connected to form a flow channel 123 for airflow. That is, the airflow can flow through the flow channel 123 toward the outlet 114, and then flow out of the vehicle separator 100 and enter the vehicle braking system, such as flowing into the working parts of the vehicle braking system, such as the brake valve module. In addition, an external frame can be optionally configured for the impeller 120, and the external frame can be optionally installed and connected to the inner wall 110 of the housing 11 in an interference fit manner.

[0035] Impeller 120 can be configured with multiple blades, which can be arranged at a preset angle, such as an acute angle with the airflow direction, for example, 30°-60°. This allows the airflow trajectory to be altered using aerodynamic principles while impeller 120 remains stationary. Specifically, these blades on impeller 120 can directionally guide the airflow entering cavity 111 from inlet 113 as it flows through impeller 120, for example, causing deflection, turbulence, or swirl. This can facilitate the separation of target materials (such as water and / or particulate matter) in the airflow due to their different specific gravities, for example, into the cavity. Figure 2 The cover 13 shown prevents the target material from being re-mixed into the airflow. The separated airflow can flow into the outlet 114 through the flow channel 123, and then flow outward from the outlet 114, so that the airflow with the target material content removed or effectively reduced can be put into use.

[0036] The cover 13 can be configured to have a receiving portion for collecting target material, such as water, separated from the airflow. As an optional configuration, for example... Figure 2As shown, the receiving portion can be configured with two parts, namely a first part 131 and a second part 132, which are respectively arranged toward the impeller assembly 12 and the opening 112. The first part 131 toward the impeller assembly 12 can optionally be configured in a funnel shape, i.e., the funnel shape has a gradually narrowing cross-section in the direction from the first part 131 toward the second part 132, thereby facilitating better collection of target objects separated from the airflow; the second part 132 is provided with a channel 133, which connects the first part 131 to the outside of the housing 11, so that the collected target objects can be discharged outwards when needed, allowing the receiving portion to continuously maintain its capacity to contain the separated target objects.

[0037] As an optional configuration, the vehicle separator 100 can also be equipped with a sealing element 16, which can be made of the same or different material as the cover 13. In practical applications, the sealing element 16 can be detachably installed on the cover 13 to seal the aforementioned channel 133, for example, by means of a threaded connection. This makes it very convenient to quickly and easily remove the sealing element 16 from the cover 13 when needed, allowing the collected target material to flow out and be discharged from the channel 133. Then, the sealing element 16 can be reinstalled on the cover 13. The whole operation is quite time-saving, labor-saving, and efficient.

[0038] Furthermore, to better ensure the sealing performance and separation effect of the vehicle separator 100, one or more first seals 15 can be optionally installed between the cover 13 and the housing 11. For example, the first seals 15 can be installed between the cover 13 and the inner wall 110 of the housing 11. Additionally, one or more second seals 17 can be optionally installed between the sealing member 16 and the cover 13 to form an end-face sealing fit between them. For the first seals 15 and the second seals 17, any suitable seals can be used, such as O-rings made of elastic materials like rubber. For example, in… Figure 1 and Figure 2 The example demonstrates that matching structures 134, such as grooves, can be correspondingly constructed on the outer surface of the cover 13 for housing the first seal 15.

[0039] Continue to refer to Figure 4 The embodiment of the vehicle separator of this application is shown, and unless otherwise specified, the components therein may adopt the same or similar structural configuration as those in the foregoing embodiments.

[0040] exist Figure 4In the illustrated embodiment, the vehicle separator 100 is further provided with a filter 14 for filtering the target material separated by the impeller assembly 12 during operation. Part or all of the filter 14 can be arranged within the receiving portion of the cover 13, for example, within the second portion 132 of the receiving portion, and then the cover 13 with the filter 14 installed is mounted onto the housing 11. When the airflow flowing in from the inlet 113 is separated by the impeller assembly 12, the separated target material can enter the receiving portion and be filtered by the filter 14. The filter 14 can be configured to store the filtered particulate matter within itself, thereby preventing re-mixing into the airflow within the cavity 111; water filtered by the filter 14 can be collected in the receiving portion. The receiving portion can be configured to collect the filtered water, for example in… Figure 4 The example shows how water can be more easily collected at the bottom of the container. In actual use, the cover 13 can be removed periodically or irregularly as needed to clean up the collected material (e.g., water) or to replace or clean the filter 14.

[0041] Regarding the specific configuration type of filter 14, it can be designed or adjusted according to the actual application needs of, for example, vehicle braking system, such as the specific requirements for particulate matter to be treated, and this application does not impose any restrictions on this.

[0042] The vehicle brake separator according to this application can be designed, manufactured, and sold independently, and can be installed and applied to a vehicle braking system. This application provides such a vehicle braking system. Specifically, the working components of the vehicle braking system can be connected to the outlet of the vehicle brake separator to supply airflow processed by the vehicle brake separator to the working components. Such working components may include, but are not limited to, brake valve modules, such as foot valve modules, front axle valve modules, rear axle valve modules, trailer valve modules, etc. The working components can be used to regulate the airflow used in the vehicle braking system, such as changing the airflow pressure and flow rate, thereby controlling the vehicle braking system to provide the desired braking force. It should be understood that the vehicle braking system configured on a vehicle can be of many types, such as electronic braking systems (EBS) and / or mechanical braking systems.

[0043] This application further provides a vehicle on which the vehicle braking system according to this application can be configured. It should be noted that the vehicle according to this application can be of many types, including but not limited to gasoline vehicles, pure electric vehicles, hydrogen vehicles, and hybrid vehicles.

[0044] The above examples illustrate the vehicle separator, vehicle braking system, and vehicle according to this application. These examples are for explaining the principles and implementation methods of this application only and are not intended to limit the application. Various modifications and improvements can be made by those skilled in the art without departing from the scope of this application. For example, the impeller assembly in the foregoing embodiments is configured with a first bracket and a second bracket; however, in one or more embodiments, the impeller assembly can be configured with other forms of brackets, such as three or more brackets, or only one bracket with the impeller mounted to the end of the bracket. Therefore, all equivalent technical solutions should fall within the scope of this application and are defined by the claims of this application.
