According to some embodiments of the present invention, as shown in fig. 1, 3-5, the oil guide plate 210 includes a swash plate portion 211, an arc plate portion 212, and a flat plate portion 213.
The swash plate portion 211 is located on one side in the radial direction of the connecting shaft 141 of the counter gear 140, for example, the swash plate portion 211 is located on one side of the lubricating oil splashed by the connecting shaft 141 of the counter gear 140 toward the differential gear 110, the swash plate portion 211 extends obliquely from bottom to top in the direction of the connecting shaft 141 of the counter gear 140, the arc plate portion 212 is connected to the swash plate portion 211, the arc plate portion 212 is configured as an arc flat plate protruding in the direction of the connecting shaft 141 of the counter gear 140, the arc plate portion 213 is connected to the arc plate portion 212, and the flat plate portion 213 extends from the arc plate portion 212 in the direction away from the connecting shaft 141 of the counter gear 140.
The oil blocking portion 201 is formed on one side of the flat plate portion 213 facing the direction of the splashed lubricant, and the side dams 220 are connected to the swash plate portion 211, the arc plate portion 212, and the flat plate portion 213, respectively.
Thus, the lubricating oil splashed by the differential gear 110 is mainly splashed onto the arc-shaped plate portion 212, and the arc-shaped shape of the arc-shaped plate portion 212 can effectively collect the lubricating oil, so that the lubricating oil which can sufficiently lubricate the secondary shaft bearings can be collected in the oil guide plate 210. Then, the lubricating oil splashed on the arc plate portion 212 flows toward the bevel plate portion 211 by the centrifugal force of the differential gear 110, and then flows toward the arc plate portion 212 and the counter shaft bearing along the bevel plate portion 211 by the gravity, so that the bevel plate portion 211 can effectively guide the lubricating oil so that the lubricating oil can be continuously adhered to the oil guide plate 210 and the lubricating oil can be guided by the oil guide plate 210 to flow toward the counter shaft bearing.
For example, after the flat plate portion 213 is installed on the box 100, the upper surface of the flat plate portion 213 may be kept horizontal, or the upper surface of the flat plate portion 213 may be kept approximately horizontal, so that after the lubricant flows from the arc-shaped plate portion 212 to the flat plate portion 213 under the action of gravity, the flat plate portion 213 and the oil blocking portion 201 can together act as a stop and a reservoir for the lubricant, thereby improving the effect of the oil guiding plate 210 in retaining part of the lubricant.
