Active lubrication structure of differential mechanism with differential lock

Abstract

The invention discloses an active lubricating structure of a differential mechanism with a differential lock, which comprises a gearbox shell, a differential mechanism bearing support, a first shaft hole arranged on the differential mechanism bearing support, a differential mechanism bearing and a differential mechanism, the differential mechanism comprises a differential mechanism shell with second shaft holes formed in the two ends, a half axle gear, a planetary gear assembly, a differential lock assembly and a sun wheel shaft. A shell oil duct is arranged on the gearbox shell, bearing support oil ducts are arranged on the differential bearing supports, and outlets of the bearing support oil ducts are connected with the first oil cavity. An annular gap between the sun wheel shaft and the second shaft hole forms a differential oil duct which is connected with the interior of the first oil cavity. A half axle gear oil duct is arranged on the half axle gear, a bearing oil duct is arranged on the differential mechanism shell, and a differential lock oil duct is arranged on the differential mechanism shell. By arranging the lubricating oil channels, active lubrication of all assemblies of the differential mechanism is achieved, and the technical problems that in the prior art, passive splash lubrication is adopted, lubrication is insufficient, and early abrasion is likely to be caused are solved.

Description

technical field [0001] The invention relates to the technical field of tractor transmission systems, in particular to an active lubricating structure of a differential gear including a differential lock. Background technique [0002] In recent years, the market demand for high-power wheeled tractors in my country has gradually expanded. Especially in the northwest, north and northeast regions, heavy-duty wheeled tractors occupy a dominant position in the market, which requires the tractor transmission system to have safer and more reliable performance. [0003] However, the differentials and differential locks used in the drive trains of large and medium-sized tractors produced in my country are widely used in splash lubrication. Passive lubrication is achieved by opening holes in the differential housing and stirring oil in the gears. The reliability of splash lubrication is poor, especially when the tractor is working in an inclined state, it is easy to cause early wear or...
