Abstract
Disclose a kind of system, the system is used for by the way that the oil scraped around differential casing is led through shell (1,7) the tapered segment towards bearing (6) come lubricate rotated in the shell differential mechanism output the bearing (6), it is characterized in that, oil is guided towards the bearing by the thick casting passage (4) provided in the inner wall of the shell, the channel is open in the middle part of the height of bearing.
Description
The present invention relates to the Drive differentials in particular for road vehicle, and more particularly to differential mechanism rolling bearing
And sealing differential mechanism or mechanism shell rotating ring lubrication the problem of, which is resisted against on transmission shaft, by the movement of differential mechanism
It is transferred to the wheel of vehicle.
More precisely, the theme of invention is a kind of lubricating system, which is used for by by differential mechanism ambient envelope
The oil scraped is led through the tapered segment towards rolling bearing of shell to lubricate the differential mechanism rotated in shell output and roll
Bearing.
Another theme of the invention is gear box clutch and differential casing and mechanism shell and including these
The gear-box of shell.
When being kept in motion vehicle, the rolling bearing needs rotated from gear-box guidance differential lines are lubricated.On
It states situation and is also applied for dynamics lip sealing ring, which is resisted against on transmission shaft.
Open file US 6 186 277 discloses the differential casing with the oily guider being integrated on its inner wall.
The rolling bearing orientation of transmission shaft of the oil that these guiders allow to throw enclosure interior from shell towards two output place.?
In Contemporary Design, available space is very limited between differential mechanism shell and shell, degree achieved be these articles almost
It is adjacent.When it is particularly the case, either by the way that guider is integrated in the practical inner wall of shell, or by adding
Be added in the internal attachment component for being fixed to housing wall, add inside housings guider be all in practice it is impossible or
Be at least implement it is extremely difficult.
The present invention seeks the oil that will be scraped from the conical inboard wall of shell efficiently towards there is region to be lubricated to orient.
Thus, it is proposed that by the pipeline being casted into outer casing inner wall and the opening among the height of rolling bearing come direction
Bearing guidance oil.
Preferably, oil is imported into the rear ends of shell by the bottom wall through pipeline.
The lubricating system proposed has found in mechanism shell or non-in the clutch and differential casing of gear-box
Limited application.
By reading to the following explanations of a nonlimiting examples of the invention and referring to attached drawing, of the invention other
Feature and advantage will become clear, in the accompanying drawings：
- Figure 1A and 1B illustrates the first layout of the shell for lubricating transmission rolling bearing,
- Fig. 2A and 2B illustrates currently preferred shell layout, and
- Fig. 3 A and 3B show its alternative form.
It is the view from clutch and differential casing (1a, 1b) in terms of cabinet end in Figure 1A, it can be seen that be used for vehicle
The passage opening 2 of the right side transmission shaft of preceding bridge.Arrow f indicates the rotation side of the differential case (not depicting) in forward gear
To.It can see the interior rib 3 and slot or pipeline 4 of being cast in upper position on the inner wall of differential casing 1b, and
Rib in being cast in, which is intended to strike off, is transported the oil struck off by rib 3 towards opening 2 by differential mechanism shell entrained oil, slot or pipeline
It send.It is next to boss 5 in rib 3, the protrusion (not depicting) of the clutch mechanism at the boss and the rear portion shell 1b is opposite
It answers.
Right-side differential rolling bearing 6 to be lubricated is depicted in the sectional elevation of Fig. 1 b.Rolling along rib 3 on right side
The desired theoretical path that oil is transported behind dynamic bearing 6 is indicated with dotted line.The path observed during the test is by solid line
Arrow is indicated：It is in fact possible to observe, in use, oil is before the back wall for reaching shell in the effect of gravity
Under fall on boss 5.When this situation occurs, rolling bearing is not lubricated.
In this example, as many other designs, shell or mechanism shell comprising gear draw box mechanism, which have, to be arrived
The differential mechanism of the near front wheel exports, and differential mechanism output has left differential mechanism rolling bearing.Then, clutch and differential casing branch
Hold right side rolling bearing.This method includes striking off by differential mechanism rotating entrained oil, and oil is guided behind rolling bearing.Pipe
Road 4 bearing upper opening, to make to maximize under gravity in the tail oil mass of rolling bearing.This cloth
The benefit set is economy, because it is only limitted to directly obtain arrangement in shell cast.It, which limits to, is related to shell in receiving differential
Specific shape in the shell area of device shell, substantially conical.Specifically, the axis of rolling in the back for reaching shell
Before holding, under gravity, the oil of significant ratio, which is fallen, to be returned on differential mechanism shell.
Enlarged drawing in Fig. 2A and Fig. 2 B shows mechanism shell 7, passage opening 2 and the axis of rolling for left side drive shafts
Hold 6.As shown in Figure 1, arrow f indicates the direction of rotation of transmission shaft in forward gear.It is formed in the inner wall of shell in being cast in
Pipeline 4, to guide oil towards rolling bearing.Compared with example above-mentioned, determining for the pipeline 4 being casted into inner walls is had modified
To.It is open in the middle position of rolling bearing 6, rather than at top.Oil can be with mode as before from differential mechanism
It is wiped off on shell, such as uses rib (it is reappeared not in the drawings).As specified by Fig. 2 B, some oil thus collected are through pipeline
4 bottom wall is guided towards left side rolling bearing.
Because oil needs to overcome positive horizontal variation, about the limitation of shell demoulding to reach the back of shell.In order to mention
The validity of high solution needs to realize the relief angle (d é pouille r é duite) of reduction in this region in the region
In (0.5 ° to 1 ° rather than 2 ° common).In view of maximum duct length is 80mm (known envelope value), level variation is less than
1mm.The flowing dynamics of oil are assigned during scraping, and the oil level generated within the duct 4 allows the back to shell to supply
Oil.Therefore, the oil of significant ratio can reach the back of rolling bearing from shell towards outlet.
This solution meets with the functional requirement of the rolling bearing of inexpensive lubrication, this is because it does not draw
Enter any additional components related to this or any attachment device.The group of cabinet is not also simplified using additional component
Part.How to be installed according to differential mechanism shell, can be applied to differential clutch shell, be applied to mechanism shell or
Applied to the two.
In order to increase the effect of lubricating system, for example pipeline can be optimized by increasing additional oily induction element 8
Shape, such as in the non-limiting example in Fig. 3 A and Fig. 3 B, which is the former expansion.Induction element 8 from
The back of pipeline is prominent towards the inside of shell 7, preferably to use pipeline oil.
This lubricating system can notably be integrated to mechanism shell or be integrated to the clutch and differential of gear-box
In device shell.Therefore, lubricating system according to the present invention can be integrated in each of which shell by gear-box.
