[0002] The vehicle's drive assembly is provided with a vent plug to connect the inside and outside of the drive assembly so that the air pressure inside and outside is balanced. The drive assembly is pre-filled with an appropriate amount of gear oil, and the gear oil is splashed by the gear meshing and high-speed rotation, so that the gear oil covers the surface of each transmission part to achieve a lubrication effect. However, the gear oil splashed everywhere enters the vent plug and gathers therein, which will clog the vent plug or overflow from the vent plug to the outside of the drive assembly, causing a malfunction. Usually, an oil retaining member is provided at the position corresponding to the vent plug inside the drive assembly to prevent the gear oil from entering the vent plug.

[0044] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0045] like Figure 1As shown, the first aspect of the utility model discloses a drive assembly. The drive assembly includes a housing 110, a vent plug 120 and an oil stopper tube 130. The housing 110 has an opening 111. The vent plug 120 is arranged on the housing 110, and the vent plug 120 has a gas passage, at least part of which is located on the outside of the housing 110. The vent hole 121 of the vent plug 120 corresponds to the opening 111, so that the inside and outside of the drive assembly are connected through the opening 111 and the vent plug 120. The oil stopper tube 130 is arranged on the inner surface of the housing 110, and the first end of the oil stopper tube is connected to and connected with the opening 111. An oil stopper portion 131 is arranged in the oil stopper tube 130. One side of the oil stopper portion 131 is spaced apart from the inner surface of the oil stopper tube 130, so that gas can flow through the oil stopper tube 130. The oil stopper portion 131 extends through the axis AX of the oil stopper tube 130.

[0046] According to the utility model, both ends of the oil retaining tube 130 are open, so that the gas inside and outside the drive assembly can circulate, ensuring that the pressure inside and outside is consistent, and preventing the internal pressure from being too high to damage the seal and cause oil leakage. The side wall can block the gear oil splashing from all around. The oil retaining part 131 is arranged inside the oil retaining tube 130, so that the gas can circulate, and the gear oil entering from the port of the oil retaining tube 130 will be blocked by the oil retaining part 131 and cannot enter the vent plug 120, thereby preventing the vent plug 120 from being blocked or leaking oil.

[0047] Further, the oil blocking portion 131 is configured such that the area of ​​the fluid flow passage in the oil blocking tube 130 between the oil blocking portion 131 and the inner surface of the oil blocking tube 130 is less than or equal to one third of the cross-sectional area of ​​the oil blocking tube 130 along the axial direction of the oil blocking tube. In other words, the size of the oil blocking portion 131 along the radial direction of the oil blocking tube 130 is greater than or equal to two thirds of the cross-sectional area of ​​the oil blocking tube 130 along the axial direction. Thus, the blocking area of ​​the oil blocking portion 131 is larger, and more gear oil can be blocked from entering the vent plug 120.

[0048] In this embodiment, the oil retaining portion 131 has an oil retaining plane facing the second end of the oil retaining tube 130, and the oil retaining plane is perpendicular to the axis AX of the oil retaining tube 130, so that production is more convenient and cost-saving. The second end of the oil retaining tube 130 is opposite to the first end. It can be understood that the oil retaining plane of the oil retaining portion 131 can also be inclined to the radial direction of the oil retaining tube 130, inclined obliquely upward or obliquely downward, so that the gear oil accumulated on the oil retaining plane of the oil retaining portion 131 can more easily flow back to the inside of the drive assembly.

[0049] Preferably, the oil stop tube 130 includes at least two oil stop portions 131 spaced apart along the axial direction of the oil stop tube 130 , and at least two oil stop portions 131 are staggered along the radial direction of the oil stop tube 130 , so that at least a portion of the gas flow channel within the oil stop tube 130 reciprocates through the axis AX of the oil stop tube 130 . Figure 1The direction of the middle arrow is the flow path for the gas inside the drive assembly to flow outward, and at least two oil baffles 131 are arranged in a staggered manner so that at least part of the gas flow channel forms a reciprocating curved shape, that is, at least part of the gas flow channel is constructed as a serpentine curve, so that the projection of the oil baffle 131 along the axial direction completely covers the vent hole 121 of the vent plug 120, further blocking the gear oil from entering the vent plug 120.

[0050] like Figure 2 As shown, the oil blocking tube 130 includes a tube body, and the side wall of the tube body is provided with a notch 132 matching the oil blocking portion 131, and the oil blocking portion 131 is plugged and matched with the tube body through the notch 132, that is, the oil blocking portion 131 is inserted into the notch 132 and fixed on the notch 132, and the oil blocking portion 131 extends from the notch 132 to the inside of the oil blocking tube 130 to pass through the axis AX. For example, when producing the oil blocking tube 130, a notch 132 is opened in the side wall of the oil blocking tube 130, and the oil blocking portion 131 is inserted into the notch 132 from the outside, and then the oil blocking portion 131 is connected to the oil blocking tube 130 by welding and the oil blocking portion 131 and the oil blocking tube 130 are sealed. Thereby, time is saved in the production process and production efficiency is improved. It can be understood that the blocking portion can also be arranged in the oil blocking tube 130 in other ways. When the oil retaining tube 130 has at least two oil retaining portions 131 , the at least two notches 132 are correspondingly spaced apart in the axial direction and arranged alternately to match the oil retaining portions 131 .

[0051] For example, the oil blocking tube 130 can be configured as a cuboid, and the oil blocking portion 131 can be configured as a rectangular sheet. The oil blocking tube 130 and the oil blocking portion 131 can also be configured in other shapes, for example, the oil blocking tube 130 is configured as a cylinder, and the oil blocking portion 131 is configured as a fan-shaped sheet. The oil blocking tube 130 has a surrounding side wall that can block the gear oil splashing around, and the oil blocking portion 131 can block the gear oil entering from the port.

[0052] like Figure 1 As shown, in one embodiment, the port of the oil retaining tube 130 faces the non-rotating member 300. The non-rotating member 300 is an inner gear ring, and planetary gears are arranged inside to rotate and mesh, and the gear oil is inside the non-rotating member 300. When the planetary gears rotate and mesh, gear oil will splash out axially from the inner gear ring, but because the inner gear ring is fixed and does not rotate, its outer surface will not directly produce radially splashed gear oil due to gear meshing. Therefore, during operation, no lubricating oil will splash toward the vent plug 120, so that only a small amount of gear oil enters the oil retaining tube 130 through reflection, and the oil retaining portion 131 can block the gear oil.

[0053] like Figure 3As shown, in another embodiment, the port of the oil stop tube 130 is not facing the non-rotating part 300, so that a relatively large amount of gear oil will enter the oil stop tube 130 from the port, and it cannot be completely blocked by the oil stop portion 131 alone. Therefore, the drive assembly also includes an oil stop cover 140. The oil stop cover 140 is arranged on the inner surface of the housing 110, and the projection of the oil stop cover 140 along the axial direction of the oil stop tube 130 covers the oil stop tube 130. The oil stop cover 140 is provided with a vent to allow gas to circulate. As a result, the oil stop cover 140 can block most of the gear oil entering from the port, and can effectively prevent a large amount of gear oil from directly impacting the inside of the oil stop tube 130. A small amount of gear oil entering by reflection is blocked by the oil stop portion 131, forming a double protection for the vent plug 120, and further preventing the vent plug 120 from being blocked or leaking oil.

[0054] like Figure 4 As shown, in the present embodiment, the oil shield 140 is configured in a U-shape. Both ends of the oil shield 140 are connected to the inner surface of the housing 110, and the bottom of the oil shield 140 is spaced apart from the oil shield pipe 130 and covers the oil shield pipe 130. For example, both ends of the oil shield 140 are configured to have flanges, and the flanges are attached to the inner surface of the housing 110 to fix the oil shield 140. The openings on both sides of the oil shield 140 are formed as vents to allow gas to circulate, and the gear oil splashed from both sides can be blocked by the side walls of the oil shield pipe 130.

[0055] Exemplarily, the outer peripheral surface of the vent plug 120 near the end of the housing 110 is provided with an external thread. The inner peripheral surface of the opening 111 of the housing 110 is provided with an internal thread that matches the external thread of the vent plug 120, that is, the vent plug 120 is threadedly connected to the housing 110. It can be understood that the vent plug 120 can also be connected to the housing 110 in other ways, for example, the vent plug 120 is provided on the outer surface of the housing 110 and surrounds the opening 111.

[0056] like Figure 5 As shown, in one embodiment, at least part of the housing 110 is constructed as a trapezoidal boss, and the trapezoidal boss includes two symmetrical inclined surfaces and a connecting plane connecting the two inclined surfaces, and the opening 111 is arranged on the connecting plane of the trapezoidal boss. In the case where at least part of the housing 110 is constructed as a trapezoidal boss, when the drive assembly is installed on the vehicle, the inclined surface of the trapezoidal boss is used to correspond to the beam 200 of the vehicle, so it is closer to the beam 200 of the vehicle. If the vent plug 120 is arranged on the inclined surface of the trapezoidal boss, under extreme working conditions, the vent plug 120 may collide with the beam 200, so it is arranged on the connecting plane of the trapezoidal boss. There is more gear oil splashing here, and the oil retaining pipe 130 plays a better oil retaining role. It can be understood that the oil retaining pipe 130 can also be used for the housing 110 constructed as an arc.

[0057] The second aspect of the utility model discloses a vehicle, which comprises a drive assembly according to the above technical solution.

[0058] According to the utility model, the vehicle includes the above-mentioned drive assembly, so the vehicle has a technical effect similar to that of the drive assembly.

The features described herein in one embodiment may be applied to another embodiment alone or in combination with other features, unless the feature is not applicable or otherwise specified in the other embodiment.
