Problems solved by technology

The drive axle is a load-bearing part as well as a transmission part. It contains a long transmission chain inside. The traditional axle design only considers the normal transmission between each group of transmission chains under the premise of meeting the strength and service life, but does not consider the transmission belt. The size of the power loss, resulting in low transmission efficiency of the axle assembly, high fuel consumption, large emissions, while increasing user costs, it also pollutes the environment

Abstract

The invention discloses a heavy truck drive axle structure assembly with high transmission efficiency, which is characterized by consisting of an input shaft assembly, a main cone shaft assembly, a differential shaft assembly, an axle housing assembly, a hub assembly, a driving cylindrical gear, a driven cylindrical gear, a driving bevel gear and a driven bevel gear, compared with a traditional structure, the whole drive axle assembly is started from reducing gear meshing power loss, bearing friction loss and rotating piece oil stirring loss, various item parameters such as gears, bearings, a differential mechanism assembly and gear oil of an internal transmission system are refined and improved, the transmission efficiency can be improved as much as possible, and the service life of the drive axle assembly is prolonged. And the driving efficiency of the automobile is better improved, so that the oil consumption is reduced, the emission is reduced, and the system adapts to the general background of energy conservation, emission reduction and ecological protection advocated by the country and is greatly welcomed by automobile manufacturers and users.

Description

technical field [0001] The invention relates to the technical field of heavy truck vehicle axles, in particular to a high transmission efficiency heavy truck drive axle structure assembly. Background technique [0002] The drive axle will produce certain internal losses during the mechanical transmission process, including mechanical loss and hydraulic loss, mainly composed of gear meshing power loss, bearing friction loss and oil churning loss of rotating parts such as gears and differential housings. Efficiency is directly related to how much power is lost in the driveline. Transmission efficiency is one of the important indicators to measure the working performance of the drive axle system. By improving the transmission efficiency, the driving efficiency of the vehicle can be improved, thereby reducing fuel consumption and emissions. [0003] The traditional heavy truck drive axle structure assembly only considers the strength, life and reliability of each assembly compo...
