Planetary reduction device, drive axle assembly and vehicle

Abstract

The invention discloses a planetary deceleration device, a drive axle assembly and a vehicle. The planetary deceleration device comprises a casing, a ring gear, a planetary wheel assembly, a planetary carrier, a planetary wheel shaft and an oil guide. An oil pool containing lubricating oil is formed in the casing, the ring gear is fixedly connected to the casing, the planetary gear assembly is engaged with the ring gear, the planetary gear shaft is arranged on the planet carrier, the planetary gear assembly is sheathed on the planetary gear shaft, the planetary gear assembly and the Bearings are arranged between the planetary wheel shafts, an oil guide flow path is arranged in the planetary wheel shaft, an oil inlet and an oil outlet communicated with the oil guide flow path are arranged on the planetary wheel shaft, and the oil guide piece is connected with the planet carrier to be driven by the planet carrier When rotating, a part of the oil guide is located in the oil pool, and the oil guide is configured to guide the lubricating oil in the oil pool to the oil inlet during rotation, and the lubricating oil in the oil guiding flow path enters the bearing through the oil outlet. According to the planetary deceleration device of the present invention, by arranging the oil guide member on the planet carrier, the lubricating efficiency and lubricating effect of the planetary deceleration device are greatly improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a planetary speed reduction device, a drive axle assembly and a vehicle. Background technique [0002] In the related art, the planetary reduction gear in the gearbox is provided with an oil guide flow path for circulating lubricating oil. However, the oil guide flow is formed by the combination of oil guide holes on multiple components in the planetary reduction gear, which makes the arrangement of the oil guide flow path more complicated, which not only increases the difficulty of assembling the planetary gear reducer, but also The extended path of the oil guide flow path is long, and the flow resistance of the lubricating oil in the oil guide flow path is relatively large, which is prone to insufficient lubrication, thereby affecting the normal operation of the planetary reduction gear. Contents of the invention [0003] The present invention aims to solve at least one of ...
