Main reducer assembly with high transmission efficiency

Abstract

The invention provides a main reducer assembly with high transmission efficiency, and belongs to the technical field of automobile driving axles. According to the main reducer assembly, the problem that as for lubricating of a main cone bearing in an existing main reducer, during high-speed operating, the amount of oil splashing into a lubricating oil way because of a driven bevel gear is too large, thus too many rolling bodies stir the lubricating oil, and then the unnecessary power loss is generated is mainly solved. The main reducer assembly is mainly characterized in that a reducer shell,a driving bevel gear, a driven bevel gear, a main cone bearing and a differential mechanism assembly are included, wherein the driving bevel gear, the driven bevel gear, the main cone bearing and thedifferential mechanism assembly are mounted in the reducer shell; and an oil way is formed in the reducer shell and internally provided with an oil throttling plug used for adjusting the amount of thelubricating oil. According to the main reducer assembly mainly used for the driving axles, the amount of the lubricating oil splashing into the oil way because of the driven bevel gear is decreased through the throttling plug of the reducer shell, the oil stirring power loss of the main cone bearing of a lubricated object is lowered, and thus the effect of improving the transmission efficiency isachieved.

Description

technical field [0001] The invention belongs to the technical field of automobile drive axles, in particular to a drive axle main reducer assembly. Background technique [0002] The drive axle is the key powertrain of the car, and the final drive is the core component of the drive axle, which is mainly responsible for transmitting the torque output by the engine to the driving wheels. When the vehicle is running, the main reducer will cause power loss while transmitting the torque, which is generally manifested as the mechanical power loss of the transmission parts and the power loss caused by the stirring of the lubricating oil during the operation of each component, especially the power loss in the main reducer. For bearing lubrication, during high-speed operation, the amount of oil splashed into the lubricating oil channel due to the passive bevel gear is too large, so that too many rolling elements stir the lubricating oil, resulting in unnecessary power loss.
