Description

Technical Field

[0001] The present invention relates to the technical field of transmission control, and in particular to a hydraulic oil circuit control device for a range-extended transmission and a control system thereof. Background Art

[0002] The extended-range transmission usually refers to the extended-range electric vehicle transmission in a hybrid system. The hydraulic oil circuit control device of the extended-range transmission is a key component used to manage and regulate the operation of the hydraulic system. It is mainly responsible for the flow direction, pressure and flow control of the hydraulic oil in the transmission to ensure the normal operation of functions such as shifting, lubrication and cooling.

[0003] In the prior art, the parts that need lubrication inside the range-extending transmission are distributed in different locations, which makes it inconvenient to lubricate the areas at different locations, and easily leads to uneven distribution of the lubrication flow.

[0004] In order to overcome the above-mentioned shortcomings, a Chinese patent of the prior art (publication number CN217653240U) discloses a transmission hydraulic oil circuit on-off control structure. The transmission hydraulic oil circuit on-off control structure has a valve sleeve sub-assembly arranged in a solenoid sub-assembly within a housing, a magnetic core body arranged in the valve sleeve sub-assembly, a back yoke sleeve arranged at one end of the housing, a spring arranged between the back yoke sleeve and one end of the magnetic core body, a valve core mounted at the other end of the magnetic core body, a conical portion arranged at the valve core end of the valve core, and the conical portion aligned with the channel on the isolation portion of the valve sleeve body. The transmission hydraulic oil circuit on-off control structure ensures that the leakage of the transmission is effectively controlled when the transmission is working, makes the flow channel structure of the oil flow simpler, has good sealing performance, reduces leakage, and improves the versatility of the structure.

[0005] To overcome the above-mentioned shortcomings, a Chinese patent of the prior art (publication number CN109654215A) discloses a hydraulic control system for a flexible steering gearbox, including a flexible steering gearbox and a hydraulic control system. The flexible steering gearbox includes a first steering shaft and a second steering shaft. The first steering shaft is provided with a first friction clutch for controlling differential speed and a second friction clutch for controlling forward and reverse rotation; the second steering shaft is provided with a third friction clutch for controlling left turn and a fourth friction clutch for controlling right turn; the first steering shaft is provided with an internal oil circuit C and an internal oil circuit D, the internal oil circuit C is connected to the first friction clutch, and the internal oil circuit D is connected to the second friction clutch; the second steering shaft is provided with an internal oil circuit A and an internal oil circuit B, the internal oil circuit A is connected to the third friction clutch, and the internal oil circuit B is connected to the fourth friction clutch. The beneficial effect is that the hydraulic system directly acts on the friction clutch inside the gearbox through the internal oil channel, eliminating the traditional steering cylinder and related connecting rods.

Continuous use of high-temperature lubrication points in the device can easily cause damage to the internal components of the range-extended transmission, affecting the service life of the range-extended transmission.

[0028] EM1 cooling and lubricating oil circuit: The lubricating and cooling oil supplied by the pump source passes through the EM1 cooling and lubricating oil channel provided on the front housing 34 of the gearbox. Under the action of pressure, the lubricating and cooling oil enters the oil channel provided in the EM1 rotor shaft 7. The oil first flows through the hole H1 provided on the EM1 rotor shaft 7. Under the action of centrifugal force, the oil passes through H1 and then reaches the EM1 right side bearing 46 through the hole provided on the assembly of the EM1 output gear 45 and the shaft 7. After lubricating the EM1 right side bearing 46, the oil flows back to the oil tank. The oil in 7 continues to flow to the left, and flows through the hole H2 provided on the EM1 rotor shaft 7. Under the action of centrifugal force, the oil cools the motor EM1 rotor body 3 after passing through the hole H2. The oil reaches the hole H3. Under the action of centrifugal force, the oil flows through the gap formed by the EM1 rotor bearing 5 and the EM1 positioning sleeve 8. A portion of the oil lubricates the EM1 rotor bearing 5. After passing through the EM1 rotor bearing 5, the oil returns to the oil tank and continues to enter the cooling and lubrication cycle. A portion of the oil cools the motor EM1 stator body 1 under the action of centrifugal force. Input shaft lubrication oil circuit: After the lubricating and cooling oil passes through the input lubricating oil port provided on the transmission case 4, a portion of the oil flows through the gap between the transmission case 4 and the second input shaft body 36 to lubricate the input shaft left bearing 40. The remaining portion of the oil flows through the hole H4 provided on the second input shaft body 36 and, under the action of centrifugal force, lubricates and cools the input shaft adjustment gasket 41. The input shaft seal 38 primarily seals to prevent leakage of the lubricating and cooling oil. The adjustment gasket 41 provides axial positioning for the input shaft right bearing 37 to ensure reliable operation. EM2 output shaft lubrication oil circuit: After the lubricating and cooling oil passes through the EM2 output shaft lubrication oil channel provided on the transmission front housing 34, it is supplied to the EM2 output shaft bearing 1 30 through the hole H5 for lubrication and cooling. The EM2 output shaft bearing 2 31 is lubricated and cooled by oil splashing; EM2 cooling and lubricating oil circuit: After the lubricating and cooling oil supplied by the pump source passes through the EM2 cooling and lubricating oil channel provided on the front housing 34 of the transmission, a portion of the lubricating and cooling oil, under the action of hydraulic pressure, enters the hole H6 provided on the front housing 34 of the transmission to lubricate the EM2 input shaft bearing 23, and the other portion of the oil enters the oil channel provided in the EM2 input shaft body 24, first flowing through the hole H7. Under the action of centrifugal force, the oil passes through the hole H7 and then passes through the hole provided on the EM2 rotor shaft body 16. It continues to flow, passes through the gap between the retaining ring 1 22 and the oil collecting plate 21, and a portion of the oil is used to lubricate the EM2 rotor bearing 2 20, and a portion is used to cool the EM2 resolver rotor 25 and the EM2 resolver stator 27. The oil then flows through the holes H8 and H9 provided on the EM2 rotor shaft body 16 to cool the EM2 rotor body 14. A portion of the oil, under the action of centrifugal force, passes through the hole H10 to lubricate and cool the EM2 rotor bearing 1 15. The oil that has lubricated the parts continues to circulate, continuously providing cooling and lubrication for the transmission. EM1 motor cooling section: The EM1 motor stator is cooled mainly through the oil injection ports provided on the left-end oil injection pipe 2 of EM1 and the right-end oil injection pipe 39 of EM1. The left-end oil injection pipe 2 of EM1 is arranged at the left end of the EM1 motor and is an annular oil injection pipe. A certain number of oil injection ports are provided on the annular oil injection pipe according to the needs of the motor EM1. Because the heat generated by the motor coil is mainly concentrated on the coil, the provided oil injection ports force the cooling oil to be sprayed directly on the left-side coil of the EM1 motor, so that the temperature of the motor EM1 is maintained within a certain temperature range for stable operation and continuous power output, ensuring the continuous and stable operation of the gearbox. Similarly, the main function of the right-end oil injection pipe 39 of EM1 is the same as that of the left-end oil injection pipe 2 of EM1, which is to ensure reliable cooling of the right side of the motor EM1. EM2 motor cooling part: The EM2 motor stator is cooled mainly through the oil injection ports provided on the left end oil injection pipe 13 of EM2 and the right end oil injection pipe 19 of EM2. The left end oil injection pipe 13 of EM2 is arranged at the left end of EM2 motor and is an annular oil injection pipe. A certain number of oil injection ports are provided on the annular oil injection pipe according to the needs of motor EM2. Since the heat generated by the motor coil is mainly concentrated on the coil, the provided oil injection ports force the cooling oil to be sprayed directly on the left coil of EM2 motor, so that the temperature of motor EM2 is maintained within a certain temperature range and stable operation is achieved, continuous power output is achieved, and continuous stable operation of the gearbox is ensured. Similarly, the main function of the right end oil injection pipe 19 of EM2 is the same as that of the left end oil injection pipe 13 of EM2, which is to ensure reliable cooling of the right side of motor EM2. Differential lubrication and related parts lubrication: Since the left differential bearing 9 and the differential body 11 are close to the bottom of the gearbox, the lubrication of the left differential bearing 9 and the differential body 11 mainly relies on splash lubrication. When the gearbox is connected to the half-shaft on the vehicle, the left differential seal 10 mainly plays a sealing role to ensure that the gearbox oil does not leak.
