[0063] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0064] Embodiment 1

[0065] See also Figure 1 , Figure 1 is a flow chart of a method for calculating the refueling amount of an air-cooled automatic transmission disclosed in an embodiment of the present application, such as Figure 1 As shown, the method of the embodiment of the present application includes the following steps:

[0066] 101. Calculate the total oil volume of the transmission hydraulic control system when the transmission is operating normally;

[0067] 102. Calculate the total oil volume of the cooling lubrication system and the torque converter hydraulic system when the transmission is operating normally;

[0068] 103. Calculate the amount of oil in the cavity below the target oil level;

[0069] 104. Determine the oil filling amount of the air-cooled mode automatic transmission based on the cavity oil volume below the target oil level, the total oil volume of the transmission hydraulic control system when the transmission is working normally, and the total oil volume of the cooling lubrication system and the torque converter hydraulic system when the transmission is working normally;

[0070] 105. Obtain the oil outflow data of the transmission oil level port under actual working conditions;

[0071] 106. Adjust the oil filling amount of the air-cooled automatic transmission based on the oil outflow data of the transmission oil level port under actual working conditions.

[0072] The embodiment of the present application calculates the total oil volume of the transmission hydraulic control system when the transmission is working normally, calculates the total oil volume of the cooling lubrication system and the hydraulic system of the torque converter when the transmission is working normally, and calculates the cavity oil volume below the target oil level surface, and can determine the refueling volume of the air-cooled mode automatic transmission based on the cavity oil volume below the target oil level surface, the total oil volume of the transmission hydraulic control system when the transmission is working normally, and the total oil volume of the cooling lubrication system and the hydraulic system of the torque converter when the transmission is working normally. On the other hand, by obtaining the oil outflow data of the transmission oil level port under the actual working conditions, the refueling volume of the air-cooled mode automatic transmission can be adjusted based on the oil outflow data of the transmission oil level port under the actual working conditions, so as to improve the calculation accuracy of the refueling volume of the air-cooled mode automatic transmission.

[0073] In the embodiment of the present application, for the air-cooled mode automatic transmission, the oil not only circulates inside the transmission, but also circulates outside the transmission for cooling. Therefore, in order to meet the demand, the oil volume of the air-cooled mode automatic transmission includes the oil volume required by the transmission hydraulic control system, the cooling lubrication system, and the hydraulic system of the torque converter. In addition, there is usually redundant oil in the oil pan, which is used for circulation. Therefore, the refueling amount of the air-cooled mode automatic transmission needs to be determined by the cavity oil volume below the target oil level, the total oil volume of the transmission hydraulic control system when the transmission is working normally, and the total oil volume of the cooling lubrication system and the hydraulic system of the torque converter when the transmission is working normally.

[0074] In the embodiment of the present application, the total oil volume of the transmission hydraulic control system when the transmission is operating normally refers to the oil volume required by the transmission hydraulic control system when the transmission is operating normally.

[0075] In the embodiment of the present application, the cooling and lubrication system and the hydraulic system of the torque converter usually work together, so the cooling and lubrication system and the hydraulic system of the torque converter can be used as an overall system.

[0076] In an embodiment of the present application, the interior of the oil pan is designed as a cavity, which is used to store transmission oil, wherein the transmission oil can form a target oil level surface in the cavity, and the amount of oil below the target oil level surface is called the cavity oil amount below the target oil level surface.

[0077] In the embodiment of the present application, step 101, step 102, and step 103 are implemented based on simulation analysis. Therefore, the refueling amount of the air-cooled mode automatic transmission calculated by step 104 is a theoretical calculated value, which may be different from the actual value. Therefore, in order to narrow the difference between the two, it is necessary to correct the refueling amount of the air-cooled mode automatic transmission calculated by step 104 based on the oil outflow data of the transmission oil level port under actual working conditions, wherein the oil outflow data of the transmission oil level port under actual working conditions reflects the difference between the two. For example, if the refueling amount of the air-cooled mode automatic transmission calculated by step 104 is the same as the actual value, then theoretically, when the oil is filled according to the refueling amount of the air-cooled mode automatic transmission calculated by step 104, the transmission hydraulic control system, the cooling and lubrication system, and the torque converter hydraulic system are all fully filled with oil, and then the transmission oil can overflow from the transmission oil level port. If the refueling amount of the air-cooled mode automatic transmission calculated by step 104 is less than the actual value, the transmission oil cannot overflow from the transmission oil level port. Furthermore, if the transmission oil overflows from the transmission oil level port, the refueling amount of the air-cooled mode automatic transmission calculated in step 104 can be reduced according to the overflow amount, so that the transmission oil just overflows the transmission oil level port. If the transmission oil is not enough to overflow from the transmission oil level port, refueling is added to the transmission oil level port so that the transmission oil just overflows the transmission oil level port, and then the refueling amount of the air-cooled mode automatic transmission calculated in step 104 is adjusted according to the refueling amount, thereby finally improving the calculation accuracy of the refueling amount of the air-cooled mode automatic transmission.

[0078] In the embodiment of the present application, in order to obtain the oil outflow data of the transmission oil level port under the real working condition, it is necessary to realize the real working condition, and the specific process is: first start the engine, the engine drives the torque converter housing, drives the oil pump to rotate, the cooling lubrication system and the torque converter hydraulic system begin to fill with oil, and the transmission oil temperature also rises. When the oil temperature rises to the opening temperature of the temperature control valve, the temperature control valve opens, so that the air-cooled cooler is filled with oil, and the cooling oil channel is filled with oil. Shift to R gear and D gear for a few seconds to fill the clutch and brake of the hydraulic control system with oil. Shift to N gear to increase the engine speed for a few seconds to fill the torque converter hydraulic system with oil. At this time, all the oil circuit systems inside the transmission are full of oil, shift to P gear, fill the parking mechanism with oil, and idle the engine.

[0079] Further, open the transmission oil level port to confirm whether the refueling amount meets the requirements. If a small amount of oil flows out, the refueling amount is accurate. If no oil flows out, add oil until it flows out, record the refueling amount, and confirm it with the calculated value to obtain the final accurate refueling amount.

[0080] In the embodiment of the present application, as an optional implementation, the step of adjusting the refueling amount of the air-cooled mode automatic transmission based on the oil outflow data of the transmission oil level port under the actual working condition includes the following steps:

[0081] Based on the oil outflow data of the transmission oil level port under the actual working condition, it is determined whether oil is flowing out of the transmission oil level port under the actual working condition;

[0082] When oil flows out of the transmission oil level port under real working conditions, the oil filling amount of the air-cooled automatic transmission remains unchanged;

[0083] When no oil flows out of the transmission oil level port under actual working conditions, increase the oil filling amount of the air-cooled mode automatic transmission.

[0084] This optional implementation can determine whether there is oil outflow from the transmission oil level port under actual operating conditions based on the oil outflow data of the transmission oil level port under actual operating conditions, and can thereby maintain the refueling amount of the air-cooled mode automatic transmission unchanged when there is oil outflow from the transmission oil level port under actual operating conditions, and increase the refueling amount of the air-cooled mode automatic transmission when there is no oil outflow from the transmission oil level port under actual operating conditions.

[0085] In the embodiment of the present application, as an optional implementation, the step of increasing the refueling amount of the air-cooled mode automatic transmission includes:

[0086] Determine a target refueling amount, wherein the target refueling amount is used to fill the transmission oil level until oil flows out;

[0087] The fuel filling amount of the air-cooled mode automatic transmission is increased based on the target fuel filling amount.

[0088] This optional implementation can determine a target refueling amount, wherein the target refueling amount is used to increase the transmission oil level until oil flows out, and then the refueling amount of the air-cooled mode automatic transmission can be increased based on the target refueling amount.

[0089] In the embodiment of the present application, as an optional implementation, the step of calculating the total oil volume of the transmission hydraulic control system when the transmission is working normally includes the following steps:

[0090] Simulating and analyzing the transmission oil filling flow rate and the filling time of the first filling process;

[0091] Based on the transmission oil filling flow rate and the filling time of the first filling process, the total oil volume of the transmission hydraulic control system when the transmission is working normally is calculated, wherein the first filling process is the process of filling the transmission hydraulic control system when the air-cooled mode automatic transmission is working normally.

[0092] This optional implementation manner can simulate and analyze the transmission oil filling flow rate and the filling time of the first oil filling process, and then can calculate the total oil volume of the transmission hydraulic control system when the transmission is operating normally based on the transmission oil filling flow rate and the filling time of the first oil filling process, wherein the first oil filling process is the process of filling the transmission hydraulic control system when the air-cooled mode automatic transmission is operating normally.

[0093] For this optional implementation, the first oil filling process is implemented based on the transmission hydraulic control system, wherein the transmission hydraulic control system includes components such as an oil pan, a suction filter, a double-vane pump, a hydraulic valve body, a hydraulic control oil circuit, a brake, a clutch, and a parking mechanism. Figure 2 , Figure 2 Schematic diagram of the principle of a transmission hydraulic control system disclosed in the embodiment of the present application. Figure 2 As shown in the figure, the first oil filling process is that the transmission oil is filtered from the oil pan by the suction filter through the double vane pump and then enters the hydraulic valve body, and the hydraulic valve body distributes the oil and controls the pressure, so that the transmission oil flows to the clutch and brake piston, the parking lock hydraulic valve, etc. Furthermore, by controlling the clutch and parking lock to engage and disengage, the transmission shifting and parking functions are realized.

[0094] In the embodiment of the present application, as an optional implementation, the step of calculating the total oil volume of the cooling lubrication system and the hydraulic system of the torque converter when the transmission is working normally includes the following sub-steps:

[0095] Simulate and analyze the transmission oil filling flow rate and filling time of the second filling process;

[0096] Based on the transmission oil filling flow rate of the second oil filling process and the filling time of the second oil filling process, the total oil volume of the cooling lubrication system and the torque converter hydraulic system when the transmission is working normally is calculated, wherein the second oil filling process is the process of filling the cooling lubrication system and the torque converter hydraulic system when the air-cooled mode automatic transmission is working normally.

[0097] This optional implementation manner can simulate and analyze the transmission oil filling flow rate of the second oil filling process and the filling time of the second oil filling process, and then can calculate the total oil volume of the cooling lubrication system and the torque converter hydraulic system when the transmission is working normally based on the transmission oil filling flow rate of the second oil filling process and the filling time of the second oil filling process, wherein the second oil filling process is the process of filling the cooling lubrication system and the torque converter hydraulic system when the air-cooled mode automatic transmission is working normally.

[0098] For this optional implementation, the second oil filling process is implemented based on the cooling lubrication system and the hydraulic system of the hydraulic torque converter, wherein the cooling lubrication system and the hydraulic system of the hydraulic torque converter include an oil pan, a suction filter, a double-vane pump, a hydraulic valve body, a temperature control valve, an air-cooled cooler, a cooling oil channel, a main shaft, a clutch, a brake, a planetary gear, a bearing, a hydraulic torque converter and other components. For further information, please refer to Figure 3 , Figure 3 Schematic diagram of the principle of a cooling and lubrication system and a hydraulic system of a hydraulic torque converter disclosed in the embodiment of the present application. Figure 3 As shown, the second oil filling can be the transmission oil from the oil pan through the oil pump and filtered by the suction filter and then enter the hydraulic valve body. The hydraulic valve body performs oil circuit distribution and pressure control, so that the transmission oil flows out from the cooling oil port of the transmission housing and flows to the temperature control valve. The temperature control valve controls whether the cooling oil circuit enters the air-cooled cooler. The rear transmission oil flows in through the cooling oil port of the transmission housing and flows to the main shaft through the cooling oil channel. The transmission oil is distributed by the main shaft and enters the clutch, brake, planetary gear, bearing and other parts for cooling and lubrication, and enters the torque converter to achieve the separation and combination of power transmission and locking clutch and the cooling and lubrication of related parts. Since the transmission runs under high-speed operation and high temperature conditions, it will cause wear on the tooth surface of the shaft and the bearing, so it needs sufficient lubrication and cooling to ensure and extend the service life and prevent the clutch and brake from burning; an oil film is formed inside to isolate the air and prevent rust and corrosion; at the same time, it can also be cooled to reduce the heat generated during use.
