The transmission mechanism may comprise a separate drive mechanism or a separate gear change mechanism, or a drive mechanism and a gear change mechanism. The drainage assembly provided by the embodiment of the application is suitable for any equipment or system with a plurality of diversion objects, and the drainage assembly is applied to a transmission system.

Taking a speed change mechanism as an example, the existing lubrication and cooling will be exemplified. In general, a transmission mechanism changes the running speed of a vehicle and the torque of a driving wheel by changing a transmission ratio, so that a motor of the vehicle can operate in the most favorable state under any working condition. The traditional speed change mechanism adopts a splash type passive lubrication scheme, and splash lubrication refers to lubrication by using lubricating oil thrown out by the speed change mechanism due to centrifugal force in the transmission process. The thrown lubricating oil lubricates and cools the gear structure and the related rotating shaft and bearing in the speed changing assembly in a random splashing mode.

Since the power for throwing out the lubricating oil is derived from the centrifugal force generated in the transmission process of the gearbox, the magnitude of the centrifugal force depends on the magnitude of the rotating speed, and the magnitude of the rotating speed depends on the actual working condition of the current vehicle, the throwing-out amount and throwing-out efficiency of the lubricating oil are greatly affected by the working condition of the vehicle. The real-time working condition of the vehicle is determined by the current practical environment of the vehicle, so that the speed change assembly is lubricated and cooled by throwing oil in random directions, the throwing amount is difficult to maintain at a stable required amount, and the stability is poor. Furthermore, since the lubricating oil obtained by the oil slinging is reused and the object to be lubricated and cooled cannot be received comprehensively and accurately by the splash method, it is difficult to generate timely and effective cooling of the transmission assembly, and the splash lubricating oil has low lubrication and cooling efficiency for the transmission assembly.

Based on the above considerations, in order to enable active, high-stability, high-efficiency, comprehensive and accurate lubrication and cooling of the transmission 200, a drain assembly 400 applicable not only to the transmission 200, but also to the transmission 200 to which the drain assembly 400 is applied and to the drive assembly 100 to which the transmission 200 is applied is designed. The drainage assembly 400 is configured to drain a liquid medium in a predetermined device located outside the transmission 200 to the interior of the transmission 200, and then to shunt the liquid medium through a diversion channel of a different path to various predetermined objects including, but not limited to, gear structures and associated shafts 302a and bearings 302b in the transmission 200. Of course, the source that the drain assembly 400 may drain is not limited to being configured on the outside of the predetermined device, and may drain from any path or source, embodiments of the present application being illustrated from a predetermined device located outside of the transmission 200.

Based on the design of the drainage assembly 400, the liquid medium in the equipment located outside the transmission mechanism 200 is drained to the inside of the transmission mechanism 200, and the drained liquid medium is comprehensively and accurately shunted to a predetermined object with lubrication and cooling requirements in a shunting manner as required lubrication and cooling liquid. The liquid medium obtained by directional drainage and directional diversion replaces oil throwing obtained by a traditional speed change mechanism in a splashing mode, and is used as a source of lubricating and cooling liquid.

The preset device is disposed outside the transmission mechanism 200, and the direction in which the preset device inputs the liquid medium into the transmission mechanism 200 can be set according to actual requirements. Specifically, the setting orientation of the preset device relative to the transmission mechanism 200, the preset direction in which the preset device inputs the liquid medium to the transmission mechanism 200, the main power source in which the preset device inputs the liquid medium along the preset direction, the specific type of the preset device, and the specific position of the preset device in the oil path of the assembly of the drive assembly 100 can be selected according to actual requirements.

Referring to fig. 31, in some embodiments provided by the present application, the preset device is selected to be a motor 101, the axial direction of the motor 101 coincides with the axial direction of the transmission mechanism 200, and a liquid medium input path between the motor 101 and the transmission mechanism 200 extends along the axial direction, and the liquid medium in the motor 101 is allowed to be drained into the transmission mechanism 200 along the axial direction.
