[0047] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the embodiments of the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the embodiments of the present utility model, some well-known technical features in the art are not described.

[0048] The preferred embodiments of the present utility model are described below with reference to the accompanying drawings. It should be noted that the terms "upper", "lower" and similar expressions used herein are for illustrative purposes only and not for limitation.

[0049] In this article, the ordinal numbers such as "first" and "second" cited in the present utility model are merely identifiers and do not have any other meanings, such as a specific order, etc.

[0050] To thoroughly understand the embodiments of the present utility model, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present utility model is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the present utility model are described in detail below. However, in addition to these detailed descriptions, the present utility model may also have other embodiments.

[0051] The present utility model provides a housing device. The housing device can be used for a transmission. The transmission includes a transmission housing 110 and an oil cooler 130. The transmission housing 110 integrates a control valve. In this way, the size of the outer contour of the transmission is small, which is beneficial to the layout of the transmission in the vehicle body.

[0052] The transmission housing 110 is provided with a first medium flow channel 122 and a valve cavity 121. The valve cavity 121 communicates with the first medium flow channel 122.

[0053] Specifically, as Figures 1 to 8 shown, the transmission housing 110 includes a first housing 111 and a second housing. The first housing 111 and the second housing are connected by bolts to form a transmission cavity 113. The transmission further includes a gear set (not shown) for transmitting torque. The gear set is disposed in the transmission cavity 113. Lubricating oil is also disposed in the transmission cavity 113 for lubricating the gear set.

[0054] As Figures 2 to 6 shown, the first housing 111 has a valve cavity 121, a first medium flow channel 122, a medium bypass flow channel 123, and a second medium flow channel 124. The first medium flow channel 122, the medium bypass flow channel 123, and the second medium flow channel 124 all communicate with the valve cavity 121. The valve cavity 121 is separated from the transmission cavity 113.

[0055] The housing device further includes a valve core 125. The valve core 125 can be the valve core of an existing control valve. The valve core 125 is movably disposed in the valve cavity 121. The movement of the valve core 125 enables the valve cavity 121 to selectively communicate with the medium bypass flow channel 123 and the second medium flow channel 124, and further enables the first medium flow channel 122 to selectively communicate with the medium bypass flow channel 123 and the second medium flow channel 124. In this way, the movement of the valve core 125 can connect or disconnect the first medium flow channel 122 and the second medium flow channel 124.

[0056] When the first medium flow channel 122 communicates with the second medium flow channel 124, a heat exchange medium (such as cold water) can flow from the first medium flow channel 122 to the second medium flow channel 124.

[0057] When the connection between the first medium flow channel 122 and the second medium flow channel 124 is disconnected, the heat exchange medium cannot flow from the first medium flow channel 122 to the second medium flow channel 124.

[0058] Specifically, the valve core 125 has a first position and a second position.

[0059] When the valve core 125 is in the first position, the valve cavity 121 communicates with the medium bypass flow channel 123, thereby enabling the first medium flow channel 122 to communicate with the medium bypass flow channel 123. The valve core 125 closes the communication between the second medium flow channel 124 and the valve cavity 121, and thereby closes the communication between the second medium flow channel 124 and the first medium flow channel 122. In this way, the heat exchange medium can flow from the first medium flow channel 122 to the medium bypass flow channel 123.

[0060] As Figure 4 and Figure 6 shown, when the valve core 125 is in the second position, the valve cavity 121 communicates with the second medium flow channel 124, thereby enabling the first medium flow channel 122 to communicate with the second medium flow channel 124. The valve core 125 closes the communication between the medium bypass flow channel 123 and the valve cavity 121, and thereby closes the communication between the medium bypass flow channel 123 and the first medium flow channel 122. In this way, the heat exchange medium can flow from the first medium flow channel 122 to the second medium flow channel 124.

[0061] Please refer to Figure 1 、 Figure 2 ,and Figures 6 to 8 ,the oil cooler 130 includes an oil cooler housing 131. The oil cooler housing 131 has a separated oil flow channel and a heat exchange medium flow channel 135. The oil cooler housing 131 also has a heat exchange medium inlet 133, a heat exchange medium outlet 134, an oil inlet (not shown), and an oil outlet 132. Both the heat exchange medium inlet 133 and the heat exchange medium outlet 134 communicate with the heat exchange medium flow channel 135. Both the oil inlet and the oil outlet 132 communicate with the oil flow channel. The heat exchange medium flow channel 135 and the oil flow channel are in heat exchange cooperation.

[0062] The transmission housing 110 may be provided with a transmission oil outlet (not shown) and a transmission oil inlet (not shown). Both the transmission oil outlet and the transmission oil inlet communicate with the transmission cavity 113. The oil inlet communicates with the transmission oil outlet. The transmission oil inlet communicates with the oil outlet 132. In this way, the lubricating oil in the transmission cavity 113 can flow through the transmission oil outlet, the oil inlet, the oil flow channel, the oil outlet 132 and the transmission oil inlet in sequence and then return to the transmission cavity 113. In this way, during the process of circulating the lubricating oil, the temperature of the lubricating oil can be adjusted by the oil cooler 130. For example, cooling the lubricating oil.

[0063] As Figures 6 to 8 shown, the second medium flow channel 124 communicates with the heat exchange medium inlet 133. In this way, the second medium flow channel 124 communicates with the heat exchange medium flow channel 135. That is to say, the valve cavity 121 is connected to the heat exchange medium flow channel 135 through the second medium flow channel 124. The movement of the valve core 125 can connect or disconnect the first medium flow channel 122 and the heat exchange medium flow channel 135.

[0064] In this way, the heat exchange medium can be conveyed to the first medium flow passage 122. At this time, as Figure 6 and Figure 7 shown, by moving the valve core 125 to the second position, the first medium flow passage 122 and the second medium flow passage 124 can be communicated. As Figure 6 and 7 indicated by the arrows, the heat exchange medium flows through the first medium flow passage 122, the valve cavity 121, the second medium flow passage 124, and the heat exchange medium inlet 133 in sequence and then enters the heat exchange medium flow passage 135, and then is discharged from the heat exchange medium outlet 134 out of the oil cooler 130 and enters one end of the medium bypass flow passage 123 far from the valve cavity 121. During this process, the heat exchange medium can adjust the temperature of the lubricating oil in the oil flow passage within the heat exchange medium flow passage 135.

[0065] As Figure 8 shown, by moving the valve core 125 to the first position, the communication between the first medium flow passage 122 and the second medium flow passage 124 is disconnected. At this time, the heat exchange medium does not flow through the heat exchange medium flow passage 135 and does not adjust the temperature of the lubricating oil in the oil flow passage.

[0066] As Figures 6 to 8 shown, the medium bypass flow passage 123 is communicated with the heat exchange medium outlet 134. In this way, the medium bypass flow passage 123 is also communicated with the heat exchange medium flow passage 135. As Figure 8 shown, by moving the valve core 125 to the first position, the first medium flow passage 122 and the medium bypass flow passage 123 can be communicated. As Figure 8 indicated by the arrows, the heat exchange medium flows through the first medium flow passage 122, the valve cavity 121, and the medium bypass flow passage 123 (flowing through the connection between the medium bypass flow passage 123 and the heat exchange medium outlet 134) in sequence. During this process, the heat exchange medium does not flow through the heat exchange medium flow passage 135 and does not adjust the temperature of the lubricating oil in the oil flow passage. Thus, the setting of the medium bypass flow passage 123 enables the valve core 125 and the transmission housing 110 to form a two-position three-way valve, and the heat exchange medium can be circulated in different circulation circuits by controlling the movement of the valve core 125, and the application range of the transmission housing 110 is large.

[0067] In this embodiment, the transmission housing 110 is provided with a first medium flow passage 122 and a valve cavity 121, and the valve core is arranged in the valve cavity; in this way, the transmission housing 110 integrates a control valve, and the transmission housing 110 integrates a flow passage (the flow passage of the control valve) for the heat exchange medium flowing through the oil cooler, without additionally arranging a control valve and pipelines for the heat exchange medium to flow, the space for arranging the transmission in the vehicle is small, the structure of the vehicle is small, and at the same time, the sealing interface positions are reduced, and the risk of medium leakage is lowered.

[0068] Optionally, as Figures 1 to 6As shown, the oil cooler 130 is connected to the transmission housing 110. At this time, the oil cooler 130 and the transmission housing 110 are arranged in sequence along the arrangement direction D1. Thus, the transmission housing 110 integrates the oil cooler 130, which can facilitate the arrangement of the transmission in the vehicle body.

[0069] Specifically, as Figure 6 shown, the edge of the opening of the second medium flow channel 124 formed by the first housing 111 is connected to the edge of the heat exchange medium inlet 133 formed by the oil cooler housing 131, so that the second medium flow channel 124 communicates with the heat exchange medium inlet 133. Part of the edge of the medium bypass flow channel 123 formed by the first housing 111 is connected to the edge of the heat exchange medium outlet 134 formed by the oil cooler housing 131, so that the medium bypass flow channel 123 communicates with the heat exchange medium outlet 134. The edge of the oil inlet formed by the oil cooler housing 131 is connected to the edge of the transmission oil outlet formed by the first housing 111. The edge of the transmission oil inlet formed by the first housing 111 is connected to the edge of the oil outlet 132 formed by the oil cooler housing 131. Thus, there is no need to connect the medium bypass flow channel 123 and the heat exchange medium outlet 134, and connect the second medium flow channel 124 and the heat exchange medium inlet 133 through additional pipes. There is no need to connect the oil inlet and the transmission oil outlet, and connect the transmission oil inlet and the oil outlet 132 through additional pipes. The structure of the transmission using the transmission housing 110 is simple.

[0070] Optionally, as Figure 7 and Figure 8 shown, the first medium flow channel 122 can also be connected to the heat exchange medium outlet 134 or the medium bypass flow channel 123 through the pipe 150 and the pump. In this way, when using the housing device, a circulation loop can be formed as needed, so that the heat exchange medium flowing through the heat exchange medium outlet 134 can return to the first medium flow channel 122, and then the heat exchange medium can be recycled.

[0071] Optionally, as Figures 1 to 6 shown, the oil cooler housing 131 is located on the side of the transmission housing 110. Thus, the structure of the housing device is simple.

[0072] Optionally, as Figures 1 to 6 shown, the oil cooler housing 131 covers the part of the transmission housing 110 that forms the valve chamber 121. In this way, along the arrangement direction D1 of the oil cooler 130 and the transmission housing 110, the valve core 125 and the oil cooler 130 are arranged in sequence. Thus, the structure of the transmission housing 110 is compact and simple.

[0073] Optionally, please refer to Figures 2 to 6 , the valve core 125 is movably arranged along the moving direction D2. The moving direction D2 is perpendicular to the arrangement direction D1 of the oil cooler 130 and the transmission housing 110. Thus, the structure of the housing device is compact and simple.

[0074] Optionally, as shown in Figure 3 Figure 3 , the axial direction of the first medium flow channel 122 is perpendicular to the moving direction D2. Thus, it is convenient to machine the first medium flow channel 122, and the structure of the transmission housing 110 is simple.

[0075] Furthermore, as shown in Figure 3 Figure 3 , the valve cavity 121 penetrates the transmission housing 110 along the moving direction D2. In this way, a medium bypass flow channel 123 is formed at one end of the valve cavity 121 in the moving direction D2. Thus, it is convenient to machine the valve cavity 121.

[0076] Please refer to Figure 2 and Figure 7 and Figure 8 , the housing device further includes a temperature sensor 140. The temperature sensor 140 is used to sense a temperature signal. The temperature signal is a signal representing the lubricating oil temperature inside the transmission housing 110. Thus, the temperature signal can be determined in real time.

[0077] As shown in Figure 4 and Figure 7 and Figure 8 Figure 8 , the housing device further includes a controller 160. The valve core 125 has a control end 126. The control end 126 includes a driving member. The working principle of the control end 126 of the valve core 125 is the same as that of the control end of an existing control valve, which will not be elaborated here. The controller 160 can be a vehicle-mounted controller. The controller 160 is electrically connected to the driving member of the valve core 125 and the temperature sensor 140. The controller 160 is configured to control the driving member according to the temperature signal sensed by the temperature sensor 140 to drive the movement of the valve core 125.

[0078] When the temperature signal indicates that the lubricating oil temperature is greater than a preset temperature value, it means that the temperature of the lubricating oil is high. In this case, the lubricating and cooling effect of the lubricating oil on the gear set is weak. At this time, the valve core 125 can be moved to the second position, and the heat exchange medium flows through the heat exchange medium flow channel 135 to exchange heat with the lubricating oil in the oil flow channel to cool the lubricating oil, thereby improving the working environment of the transmission.

[0079] When the temperature signal indicates that the lubricating oil temperature is less than a preset temperature value, it means that the lubricating oil temperature is relatively low. At this time, the viscosity of the lubricating oil is relatively large, the working resistance of the gear set increases, the energy consumption increases, and the transmission efficiency of the transmission decreases. The valve core 125 can be moved to the first position, so that the heat exchange medium directly flows out through the medium bypass flow channel 123 without entering the heat exchange medium flow channel 135. The oil does not exchange heat with the heat exchange medium in the oil cooler but enters the transmission, and the heat generated by the components such as the gear set in the transmission is transferred to the oil to increase the oil temperature.

[0080] Optionally, the temperature sensor 140 is arranged at the oil inlet. Thus, the temperature of the lubricating oil can be accurately sensed.

[0081] In an embodiment not shown, the temperature sensor may also be disposed at a position filled with lubricating oil in the transmission chamber, such as being connected to the transmission housing. At this time, the temperature sensor is disposed within the transmission chamber. Thereby, the installation of the temperature sensor is facilitated.
