様に変速機の全長が長くなるという難点がある。(Problem to be solved by the invention) Among the conventional technologies mentioned above, the one that splashes oil with the large gear of the differential does not rotate when the vehicle is stopped and the engine is idling. Therefore, there is a problem that the oil cannot be splashed up. On the other hand, the type of transmission that rotates a disc within the transmission requires space for the disc drive member and space for an oil reservoir, which has the disadvantage of increasing the overall length and height of the transmission. In addition, even if this mechanism is used inside the differential housing, the means for driving the disk must be provided on the transmission side, so there is the same problem that the overall length of the transmission becomes longer. be.

戻る。 Next, the operation of this device will be explained. The rotation of the input shaft 7 causes the transmission gear G 1 and the splash gear 23 to rotate, and the oil in the differential chamber flowing into the oil sump 35 is scooped up by the teeth 25, grooves 28, etc. of the gear 23 and carried upward, and the oil is transferred upward to the rib 30. In the open position, oil is scattered upward as oil droplets 42 and deposited on the gear group of the transmission, and the flowing oil returns to the oil reservoir again.

ことができる。 As the vehicle travels, the amount of oil splashed up by the ring gear 10 also increases, causing the bottom 11 of the transmission housing 2 to
When the amount of oil that returns to the oil reservoir 35 via the oil tank increases, the amount of oil splashed up also increases. In this state, a portion of the oil flows over the inner circumferential edge 37 of the weir plate 36 and flows down into the differential housing 4 from the valleys of the teeth 26. If the helical angle of the teeth 26 is an angle in the direction in which the oil is scooped up, the amount of oil flowing down to the differential 3 side can be reduced and a large amount of oil can be scattered. Moreover, since the splash gear 23 is provided close to the inside of the transmission 1, a large amount of oil can be sent into the transmission.

る。(Effect of the invention) As described above, since the splash gear is arranged using the space around the bearing of the differential, it is possible to provide a mechanism for splashing oil without increasing the length of the transmission and the differential at all. I can do it. Furthermore, since the mechanism operates even during idling and is provided in contact with the transmission, it has the effect of constantly scattering a large amount of oil toward the transmission.
