[0002] At present, the suction filter in the hybrid transmission sucks oil from the oil pan through an electronic pump, and then pressure executes it to the clutch through a connecting oil pipe, thereby realizing power transmission between the engine and the transmission. However, if the gear or bearing stirs the oil too much, the oil will be thrown on the shell wall, and bubbles will be generated on the shell wall. The bubbles will flow along the shell wall to the bottom of the shell.

[0024] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0025] Reference below Figure 1 and Figure 2 A transmission 100 according to an embodiment of the present invention is described. The transmission 100 is applied in a vehicle.

[0026] like Figure 1 and Figure 2 As shown, the transmission 100 according to the utility model includes: a housing 10, a running part 20 and an oil baffle 30, the running part 20 is arranged in the housing 10, the oil baffle 30 is arranged in the housing 10, and the oil baffle 30 is arranged at the bottom of the running part 20 and at least one side of the axial direction of the running part 20 to limit the movement trajectory of the oil driven by the running part 20.

[0027] It can be understood that the housing 10, the operating part 20 and the oil baffle 30 constitute the main body of the transmission 100, and the operating part 20 is located in the housing 10, so that the housing 10 can protect the operating part 20, thereby extending the service life of the operating part 20, and the operating part 20 is at least two gears or bearings, and the two gears or bearings are meshed together, so that the operating part 20 can transmit power, thereby facilitating the normal operation of the transmission 100.

[0028] In addition, the oil baffle 30 is located in the housing 10, so that the housing 10 can protect the oil baffle 30, thereby extending the service life of the oil baffle 30. The oil baffle 30 is located at the bottom and at least one side of the axial direction of the operating part 20, and the oil baffle 30 completely wraps the bottom of the operating part 20, so that the oil driven by the movement of the operating part 20 can be caught by the oil baffle 30 at the bottom. This arrangement can prevent the oil at the bottom from flying onto the housing 10, and can also prevent the oil from being converted into bubbles on the housing 10, thereby ensuring the performance of the transmission 100. The oil baffle 30 also wraps at least half of one side of the axial direction of the operating part 20. This arrangement can enable the oil baffle 30 to block the side of the oil driven by the operating part 20, so that the oil baffle 30 can catch the oil on the axial side of the operating part 20, thereby preventing the oil on the side from flying onto the housing 10.

[0029] In addition, the height of the oil baffle 30 located on the axial side of the operating part 20 is not lower than the radius of the smallest diameter of the two gears or bearings. This arrangement can prevent the oil from being thrown out due to the action of gravity and operating force, so that the oil baffle 30 can limit the movement trajectory of the oil driven by the operating part 20, thereby preventing the oil from being thrown onto the housing 10 and avoiding the housing 10 from generating a large number of bubbles.

[0030] Therefore, by arranging the operating part 20 and the oil baffle part 30 in the shell 10, the oil baffle part 30 is located at the bottom and one axial side of the operating part 20. Such an arrangement can make the oil baffle part 30 block the oil thrown out during the operation of the operating part 20, so that the oil baffle part 30 can limit the movement trajectory of the oil, thereby avoiding the generation of a large number of bubbles in the shell 10, thereby ensuring the performance of the transmission 100, avoiding the loss of additional power, and saving the cost of the transmission 100.
