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
The present invention relates to the vehicle transmission technical field, can be used for the lubrication system of the through main reducing gear of automobile, transfer case and other movable type mechanical transmission device.
Background technique
Domestic existing through main reducing gear for heavy extraordinary go-anywhere vehicle transmission system coupling, because the influence of factor such as be subjected to car load driving cycle complexity, arrangement space is limited on the chassis, the gear splash lubrication mode that it is lubricated and heat radiation adopts automobile main reducer to take usually, this lubricating system has certain narrow limitation, can't satisfy the requirement of main reducing gear proper functioning.
Summary of the invention
Technical problem to be solved by this invention provides the through main reducing gear lubricating fitting of a kind of automobile, it is compared with existing automobile main reducer lubricating system, mandatory the lubricating of can provide sufficient, locating, and this apparatus structure is simple, volume is little, increase to main reducing gear boundary dimension and quality is very little, has characteristics such as integration with main reducing gear is good, convenient for installation and maintenance, not fragile, long service life.
For solving the problems of the technologies described above, the present invention has proposed a kind of oil pump lubricating device for automobile main reducer by with plunger-type fuel pump and the integrated design of main reducing gear driving mechanism, mainly is made up of plunger 4, filter screen assembly 2, rolling bearing 6, housing 3.Oil pump device connects as one by housing and main reducing gear between centers transfer case casing, the plunger pump top by ball bearing and drive bevel gear assembly with eccentric splined shaft contact, the Plunger pump body output oil port directly is communicated with the main reducing gear internal oil channel.Above-mentioned integrated design has solved main reducing gear and has haveed no alternative but take gear splash lubrication mode can't satisfy the problem that proper functioning requires because of the chassis arrangement space is limited.This apparatus structure is simple, and is convenient for installation and maintenance, very little to the increase of main reducing gear boundary dimension and quality.
This oil pump lubricating device forms the through main reducing gear lubricating fitting of a kind of automobile by with plunger-type fuel pump and the integrated design of main reducing gear driving mechanism.This device is compared with existing automobile main reducer lubricating system, mandatory the lubricating of can provide sufficient, locating, and this apparatus structure is simple, volume is little, increase to main reducing gear boundary dimension and quality is very little, has characteristics such as integration with main reducing gear is good, convenient for installation and maintenance, not fragile, long service life.
Description of drawings
Below in conjunction with the drawings and specific embodiments technological scheme of the present invention is further described in detail.
Fig. 1 is the cross-sectional view of the specific embodiment of the invention.
The eccentric splined shaft 2-of 1-filter screen assembly 3-housing 4-plunger 5-return spring 6-rolling bearing 7-main reducing gear internal oil channel.
Embodiment
This oil pump lubricating device for automobile main reducer is made up of component such as plunger 4, filter screen assembly 2, rolling bearing 6, housings 3.Oil pump device connects as one by housing 3 and main reducing gear between centers transfer case casing, the plunger pump top by ball rolling bearing 6 and drive bevel gear assembly with eccentric splined shaft 1 contact, the Plunger pump body output oil port directly is communicated with main reducing gear internal oil channel 7, and concrete structure as shown in Figure 1.
During work, eccentric splined shaft 1 revolution drives plunger 4 and moves up and down, and realizes pump oil.The lubricant oil that oil pump pumps offers high-order gear of main reducing gear and bearing by output oil port and main reducing gear internal oil channel 7, plays lubrication.
It should be noted last that, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technological scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
