Problems solved by technology

[0003] In the traditional AMT transmission with this structure, the planetary gears and needle roller bearings in the auxiliary case are poorly lubricated. Forced lubrication is not used, but the oil mist formed by splash lubrication enters the oil passage, and the lubrication is unreliable; Forced lubrication of gearbox gears and bearings, the life of the gearbox is greatly affected

Abstract

The lubricating system of the twelve-gear AMT gearbox comprises an oil pump, a first main lubricating oil way and a second main lubricating oil way, and the oil pump is connected with a reverse gear idle gear of the gearbox; the oil pump communicates with the first main lubricating oil way and the second main lubricating oil way. The first main lubricating oil way is provided with two branches used for lubricating a rear-end retarder driven gear pair and a retarder bearing. The second main lubricating oil way is provided with seven large branches for lubricating a main box gear meshing area, a two-shaft gear inner hole needle bearing, a planetary gear meshing area, a planetary gear inner hole needle bearing, an output bearing, a one-shaft bearing, a two-shaft rear bearing, a friction element of a brake, an auxiliary box synchronizer and other parts. The lubrication cooling system is high in integration degree, reliable in lubrication, short in lubrication path, reasonable in oil way outlet distribution, small in part number, low in cost and capable of achieving precise and efficient lubrication of the auxiliary box planet row type AMT transmission.

Description

technical field [0001] The invention belongs to the technical field of lubricating devices, and relates to a lubricating system for a twelve-speed AMT gearbox. Background technique [0002] The 12-speed main and auxiliary box type AMT gearbox is 2X3X2 structure, adopts the technical scheme of main box helical single intermediate shaft + auxiliary box helical gear planetary row, adopts a new generation of integrated GSU, new CCA, and has a rear parallel retardation The transmission, forced lubrication and cooling system, reserved through-shaft power take-off interface; the transmission has short installation length, large specific torque value, high integration, and various technical parameters are at the international leading level. [0003] In the traditional AMT transmission with this structure, the auxiliary box planetary gears and needle roller bearings are poorly lubricated. Forced lubrication is not used. Instead, the oil mist formed by splash lubrication enters the oi...
