Reducer assembly and vehicle

Abstract

The invention discloses a reducer assembly. An input shaft is arranged at one end of a reducer shell of the reducer assembly, an outer bearing and an inner bearing sequentially sleeve the input shaft,and a driving gear and a driven gear are meshed with the downstream of the input shaft in sequence; a differential is arranged in the reducer shell, two half-shaft gears are arranged coaxially in a differential shell, a planetary gear shaft is arranged between the two half-shaft gears, planetary gears meshed with the half-shaft gears are coaxially arranged on the planetary gear shaft, half shaftscoaxially inserted into the corresponding half-shaft gears are arranged on the two sides of the reducer shell respectively, bearing covers sleeve the outer walls of the two sides of the differentialshell, and differential bearings are coaxially embedded between the bearing covers and the differential shell. The reducer assembly can provide reliable structural support and protection for the internal differential assembly, so that structural deformation of the assembly is avoided, and the overall structural rigidity and reliability of the equipment are ensured. The invention further disclosesa vehicle adopting the reducer assembly.

Description

technical field [0001] The invention relates to the technical field of supporting components of a vehicle transmission system, in particular to a reducer assembly. The invention also relates to a vehicle using the speed reducer assembly. Background technique [0002] In the current common transmission system structure of rear-wheel drive vehicles, since the differential is usually directly installed on the main load-carrying components such as the rear axle through the cantilever support structure, the axial force of the differential during the working process after the assembly is completed It is completely borne by its bearing cover. After the vehicle has been running for a long time, the bearing cover is very easy to expand outward due to long-term force, which is easy to cause deformation of the basic structure, and leads to the deterioration of the overall axial structural stiffness of the differential, which restricts the overall performance of related components.

[0002] In the current common transmission system structure of rear-wheel drive vehicles, since the differential is usually directly installed on the main load-carrying components such as the rear axle through the cantilever support structure, the axial force of the differential during the working process after the assembly is completed It is completely borne by its bearing cover. After the vehicle has been running for a long time, the bearing cover is easy to expand outward due to long-term force, which is easy to cause deformation of the basic structure, and leads to the deterioration of the overall axial structural stiffness of the differential, which restricts the overall performance of related components. Structural strength and reliability, and the abnormal sound of gear meshing transmission and related adapter components caused by component deformation after long-term operation is also harmful to the vehicle NVH (the acronym for Noise, Vibration, Harshness, that is, noise, vibration and harshness degrees) performance is adversely affected
