Description
Technical field
The present invention relates to a kind of switch dome cap of especially vehicle-speed variator of speed changer, this switch dome cap has at least one exhaust port, this exhaust port is closed by a hood-shaped cap seal, and wherein said lid is rabbeted a undercut portions by an engaging piece section from the back side in the exhaust port zone of switch dome cap.
Background technique
For example disclose a kind of speed changer, particularly vehicle-speed variator in DE 100 64 918 A1 He among DE 296 15 599 U1, this speed changer has a switch dome cap (switch gear).This switch dome cap exhaust towards periphery is so that avoid in switch dome cap inside and the pressure difference on every side.Be known that the switch dome cap that is provided with an exhaust port, this exhaust port like this by housing sealing, though promptly liquid (oil) can not flow out from the switch dome cap, has guaranteed with the exhaust to be the ventilation of purpose then for this reason.
A kind of known solutions of such type is shown in Figure 1.The partial view of switch dome cap 1 as can be seen here; Its further configuration example as in known document as seen.This switch dome cap 1 has an exhaust port 2, and this exhaust port is arranged on the end of hollow cylinder portion section 9.The axial end of this hollow cylinder portion section 9 forms 2 by the flanging 1 that radially inwardly points to.Direction along axis 11 sees that this flanging has a undercut portions 5.
The cylindrical form interior surface of hollow cylinder portion section 9 is by turning that is cutting.Lid 3 is inserted in the exhaust port 2 of hollow cylinder portion section 9 of the manufacturing like this that has the end side flanging, and described lid is designed to hood-shaped, and covers exhaust port under the installment state that illustrates.Described thus lid 3 and switch dome cap 1 keeps being connected, and it has a hollow cylinder portion section 13, around the engaging piece section 4 of hook-type formation be arranged on its axial end.The most outer diameter of this engaging piece section 4 is at this internal diameter greater than flanging 12.If this lid that is made of plastics 3 is pressed in the exhaust port 2 by engaging piece section 4, engaging piece section 4 ejects after moving again, is fixed on the switch dome cap 1 thereby cover 3.
Shortcoming is in this known solutions, and manufacture cost is higher relatively and this switch dome cap is therefore more expensive.This hollow cylinder portion section 9 must be through cutting fine finishing on inner diameter zone.Must process flanging in addition, necessary undercut portions so that realize for fixed cover.
Summary of the invention
Therefore the objective of the invention is to, further develop the switch dome cap that type is mentioned in a kind of beginning, making can simpler and more advantageously manufacturing.The lid that is used to cover exhaust port is therefore also fixing in the same way on function, and need not pay up to now high manufacture cost usually.
Purpose by the present invention realizes is characterized in that described undercut portions is made by an independent member.This independent member at exhaust port zone internal fixation on the switch dome cap.
This independent member is preferably designed so that ring part.This ring part can have rectangular shape on radial cross section, can form the undercut portions of a regulation thus.
The member that this is independent that is be preferably ring part exhaust port the zone in can be installed in the circular groove of switch dome cap.This circular groove preferably includes a cylindrical form interior surface with first diameter at this, and this circular groove transition is a hollow cylinder portion section, and this hollow cylinder portion section has the internal diameter less with respect to first diameter.Described transition portion from circular groove to hollow cylinder portion section can form by a supporting surface at this, and the surface normal of supporting surface points to along the direction of the axis of hollow cylinder portion section.The member that this is independent that is be preferably ring part and can advantageously be arranged in the circular groove by interference fit.Force closure and sealed being connected of shape between switch dome cap and the ring part have been realized thus.
At this preferably, known as prior art itself, the engaging piece section of hood-shaped lid is designed to hook-type on radial cross section.
This switch dome cap is preferably made by light metal, is made by aluminium or magnesium especially.Described lid mainly is made of plastics.
By can realize the manufacturing of this switch dome cap by structure of the present invention, to guarantee also that wherein mounted lid is fixed equally reliably as in known solutions with and the lower mode of explicit costs simpler with respect to prior art.The inside processing of the cutting of this hollow cylinder portion section can fully phase out.
Description of drawings
In these accompanying drawings, embodiments of the invention have been shown.Wherein:
Fig. 1:, a hood-shaped lid is installed in this switch dome cap by the part of the switch dome cap that has exhaust port of prior art;
Fig. 2: press the view according to Fig. 1 of embodiments of the invention, and
Fig. 3: by the partial view of the amplification of Fig. 2, wherein a ring part also illustrates with uninstalled state.
Embodiment
Embodiments of the invention are shown in Fig. 2 and 3.With identical in the known solutions of pressing Fig. 1, in the scheme according to Fig. 2 and 3, a switch dome cap 1 that only partly illustrates has an exhaust port 2, and this exhaust port is arranged on the end of hollow cylinder portion section 9.As in Fig. 2 as seen, exhaust port 2 is by 3 sealings of a hood-shaped lid, described lid has an engaging piece section 4 that is designed to hook-type on radial cross section.
Remain on the exhaust port 2 after it is installed in order to cover 3, a undercut portions 5 is made in the following manner.
As preferably as seen from Figure 3, on the axial end of hollow cylinder portion section 9, in the zone of exhaust port 2, make a circular groove, this circular groove comprises that one has diameter D
1Cylindrical form interior surface 8 and a supporting surface 10, the surface normal of this supporting surface illustrates along the direction of axis 11.Hollow cylinder portion section 9 under circular groove with a diameter D
2Extend this diameter D
2Less than diameter D
1
The independent member 6 of one ring part form is encased in circular groove 7, and it is mounted state in Fig. 2, but (with solid line) is also shown in before installation in Fig. 3.Ring part 6 has slightly greater than diameter D
2Diameter D
3, the direction of arrow among ring part 6 axial upper edge Fig. 3 is pressed in the circular groove 7 like this, and this ring part is installed in the circular groove with interference fit.It is located on the position shown in broken lines among Fig. 3 then.
On this mounting point, ring part 6 is formed for covering the undercut portions 5 of 3 the engaging piece section 4 that is designed to hook-type.This undercut portions 5 can not get loose from switch dome cap 1 and remain on the desirable position thus, because the outermost surface diameter D of engaging piece section 4 (referring to Fig. 2)
4Inside diameter D greater than ring part 6 (referring to Fig. 3)
5
In the installation of switch dome cap 1, carry out as follows:
At first ring part 6 is installed by axially being pressed in the circular groove 7.
If the engaging piece section 4 of hook-type is D by diameter
5Internal surface coupling, engaging piece section 4 is resilience again at least slightly, like this, is selecting diameter D
4For at least slightly greater than diameter D
5After, lid 3 is fixed on the switch dome cap
