Embodiment Construction

[0009] The oil pump lubricating device of the main reducer of the automobile is composed of a plunger 4, a filter screen assembly 2, a rolling bearing 6, a housing 3 and other components. The oil pump device is connected with the transfer case between the shafts of the main reducer through the housing 3. The top of the plunger pump is in contact with the eccentric spline shaft 1 of the driving bevel gear assembly through the ball rolling bearing 6. The pump body of the plunger pump The output oil port is directly connected with the inner oil passage 7 of the main reducer, and the specific structure is as follows figure 1 shown.

[0010] When working, the rotation of the eccentric spline shaft 1 drives the plunger 4 to move up and down to realize oil pumping. The lubricating oil pumped out by the oil pump is provided to the upper gears and bearings of the final reducer through the output oil port and the inner oil passage 7 of the final reducer to play a lubricating role.

Abstract

The invention relates to an oil pump lubricating device for an automobile main reducer, which is characterized by mainly comprising a plunger, a filter screen assembly, a rolling bearing and a shell, wherein the oil pump device is connected with the interaxial transfer case body of the main reducer into a whole through the shell; the top part of a plunger pump contacts with the eccentric spline shaft on a driving bevel gear assembly through a ball bearing; and the oil output port of the plunger pump body is directly communicated with the inner oil duct of the main reducer. Through the integration design, the invention solves the problem that the main reducer has to adopt the gear splash lubrication mode due to the restriction in chassis arrangement space so as to fail to satisfy the normal work requirements. The device has the advantages of simple structure, convenient installation and maintenance, and small increase in physical dimension and mass of the main reducer.

Description

technical field [0001] The invention relates to the technical field of automobile transmission, and can be used for lubrication systems of automobile through-type final reducers, transfer gears and other mobile mechanical transmission devices. Background technique [0002] In China, there are through-type main reducers that match the transmission system of heavy-duty special off-road vehicles. Due to the influence of factors such as the complex driving conditions of the vehicle and the limited space on the chassis, the lubrication and heat dissipation usually adopt the main reducer of the automobile The gear splash lubrication method has certain limitations and cannot meet the requirements of the normal operation of the main reducer. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a lubricating device for automobile through-type main reducer, which can provide sufficient and positioned mandatory lubrication compa...
