Abstract
The invention provides a valve assembly for cleaning lubricating oil reservoir contaminants of a transmission. The valve assembly comprises a shell, an end cover and an external channel which is axially toward outside; the channel is respectively connected with an external annular groove and an external annular channel; a sliding valve is arranged in a drilling hole by screwing a screw of an external shell; the external side of the end cover is provided with a stop element; an O-shaped seal ring is arranged at the periphery of the sliding valve; and the sliding valve is provided with an internal groove with a spring. The valve assembly disclosed by the invention is a device which can be used for cleaning contaminants from a lubricating reservoir of a limited-slip differential transmission, and can be used for cleaning contaminants in selectively jointed equipment; service life of the transmission can be prolonged and operation efficiency can be improved.
Description
Technical field
The present invention relates to a kind of differential transmission assembly, specifically a kind of speed changer valve assembly of lubricant removal chamber pollutant.
Background technique
The present speed changer with the sliding function of limit generally is lubricated by splash-lubricating system.The Lower Half of assembly is immersed in the lubricant oil, and gear movement upwards pushes lubricant oil and provides lubricated in the gear assembly, the major defect of the lubricating system of this particular type promptly: gear produces supplementary loss through the resistance to motion of oiling agent; Simultaneously, centrifugal force can make oiling agent be pushed away journal surface and cause losing efficacy; In addition, when adopting the sliding function of limit in this speed changer, tended to accumulate in this chamber by clutch and any chip that separation produced, the result has influenced the service life of speed changer.
Summary of the invention
At above defective, the purpose of this invention is to provide the valve assembly of a kind of speed changer with lubricant removal chamber pollutant, make it the working life that helps the rotation of speed changer and be bonded with each other and improve speed changer with realization.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of speed changer valve assembly of lubricant removal chamber pollutant, the external chennel that comprises housing, end cap and radial outward, described external chennel connects outside circular groove and annular pass respectively, described guiding valve is arranged in the boring by the screw that screws in frame, and the described end cap outside is provided with stopping element; Described guiding valve periphery is provided with the O RunddichtringO, and described guiding valve is provided with the inner groovy of spring.
Speed changer of the present invention with the beneficial effect of the valve assembly of lubricant removal chamber pollutant is: can be used for can removing the pollutant in this alternative junction apparatus from the lubricant reservoir of the slide limiting differential speed changer device that clears the pollution off; Prolong the working life of speed changer, improve operational efficiency.
Description of drawings
According to embodiment and accompanying drawing the present invention is described in further detail below.
Fig. 1 is the valve assembly sectional view of the described speed changer of the embodiment of the invention with lubricant removal chamber pollutant.
Among the figure:
1, frame; 2, end cap; 3, external chennel; 4, circular groove; 5, annular pass; 6, guiding valve; 7, boring; 8, screw; 9, O RunddichtringO; 10, inner groovy; 11, spring; 12, stopping element; 13, opening; 14, chamber; 15, passage.
Embodiment
As shown in Figure 1, the speed changer of the present invention valve assembly of lubricant removal chamber pollutant, the external chennel 3 that comprises housing 1, end cap 2 and radial outward, this external chennel 3 connects outside circular groove 4 and annular pass 5 respectively, guiding valve 6 moves in the boring 7 that intersect circular groove 4 and annular pass 5, described guiding valve 6 is arranged in the boring 7 by the screw 8 that screws in frame 1, and seals by O RunddichtringO 9; Described guiding valve 6 is provided with the inner groovy 10 of spring 11, and spring 11 promotes valve assemblys near cap screw 8, and described end cap 2 outsides are provided with stopping element 12, and described opening 13 and circular groove 4 are corresponding and can make lubricant oil 5 pass guiding valve 6 inside outflows from the annular pass; Described passage 80 is communicated with chamber 14 can make the parts slide relative reduce to minimum.
