Embodiment Construction

[0041] Hereinafter, a final reduction gear according to an embodiment of the present invention will be described with reference to the drawings. Such as figure 1 As shown, the final reduction gear 1 of this embodiment is a device applied to the powertrain of the vehicle V. As shown in FIG. This vehicle V is of a hybrid vehicle type and includes an internal combustion engine (hereinafter referred to as “engine”) 3 and an electric motor (hereinafter referred to as “motor”) 4 as power sources.

[0042] In this vehicle V, the power of the engine 3 and / or the electric motor 4 is shifted by the transmission 5 and transmitted to the final reduction gear 1 via the output gear 5b on the output shaft 5a of the transmission 5 . Then, the motive power is decelerated by the final reduction gear 1 , and finally transmitted to the drive wheels 7 , 7 via the left and right drive shafts 6 , 6 .

[0043] Next, the final reduction gear 1 of this embodiment will be described. figure 2 The str...

Abstract

The invention discloses a final decelerator, which can efficiently provide lubricating oil to two parts need to be lubricated, thereby improving power transmission efficiency. The final decelerator possesses a device housing, a gear ring, a bearing and a bearing part, and a valley tray. The gear ring kicks up the lubricating oil within the device housing. The bearing and the bearing part which support two drive shafts which can rotate freely. The valley tray possess a longitudinal wall which extends vertically, a first guiding wall which extrudes from the front surface of the longitudinal wall and guide the lubricating oil flowing down from the front surface to the bearing and the bearing part, and a second guiding wall 2 which positioned under the first guiding wall and extrudes from the front surface of the longitudinal wall and guides the lubricating oil flowing down from the front surface to the bearing and the bearing part.

Description

technical field [0001] The present invention relates to a final reduction gear including a guide member that guides lubricating oil to two lubricating places. Background technique [0002] Conventionally, a device described in Patent Document 1 is known as a final reduction gear device. This final reduction gear is a device for a vehicle, and is configured to input power from an engine through a transmission and distribute the input power to left and right differential output shafts. [0003] This final reduction gear includes: a device case, an input gear that is a transmission gear coupled to the output shaft, a ring gear that meshes with the input gear, a differential device that distributes power from the ring gear to left and right drive shafts for output, and a support Left and right bearings of the differential device, guide members for guiding lubricating oil to these bearings, and the like. [0004] The guide member has a groove shape with a U-shaped cross section...
