Abstract

A transmission control device has two mutually oppositely arranged counter-components, for example control boxes, and a planar transmission control plate, which is arranged between the two counter-components. The transmission control plate seals the clearance between the two counter-components or their channel portions and bores in the form of a flat seal. The plate also provides through-openings between channels or bores, respectively, in the opposing counter-components, where the fluid in the channels controls the function of a transmission. The sealing function is realized by stamped beads and/or partial coatings. Transmission control plates therefore have fluid through-flow openings so the fluid can flow through from one side of the plate to the other side of the plate. Additional functional elements can be present in the through-flow openings, for example valve elements which stop the through-flow in one direction or combined valve-orifice elements, which restrict the through-flow in one or both directions.

First claim

The invention claimed is:

1. A transmission control device having two mutually oppositely arranged counter-components and a planar transmission control plate, which is arranged between mutually opposing surfaces of the two counter-components,
wherein, formed between adjacently arranged surfaces of a respective counter-component and the transmission control plate, are fluid channels extending parallel to the plane of the respective surfaces and/or bores extending perpendicularly or substantially perpendicularly to the plane of the respective surface,
wherein the transmission control plate has at least one through-flow opening for a fluid, which penetrates the transmission control plate and mutually connects fluid channels extending on different sides of the transmission control plate, or bores extending on different sides of the transmission control plate, or a fluid channel extending on one side of the transmission control plate and a bore extending on the opposite side of the transmission control plate,
wherein the transmission control plate has at least one planar carrier layer,
wherein the transmission control plate has at least one spring element having a spring plate and a holding region for the spring plate which is connected to the spring plate and surrounds it at least in some regions, and
in that the carrier layer has, at least on a first side along a circumferential edge of the through-flow opening, a step-shaped first recess which is set back from the through-flow opening of the carrier layer in the surface of the carrier layer and in which the holding region is arranged at least in some regions;
wherein a layer of the transmission control device and/or a functional element of the transmission control device has at least one travel delimiting element for delimiting the travel of the spring plate, wherein the delimiting element is connected at at least two connecting points to the circumferential edge around the through-flow opening in the respective layer and/or in the respective functional element and the travel delimiting element, between the connecting points, in the orthogonal projection of the transmission control plate, is arranged within the through-flow opening, and at a spacing from the circumferential edge of the through-flow opening, in the respective layer and/or in the respective functional element, at least in some regions and is arranged from the spring plate in a flow-through direction.

2. The transmission control device of claim 1 , wherein, in an orthogonal projection of the transmission control plate, the spring plate is arranged in the carrier layer within the through-flow opening of the carrier layer.

3. The transmission control device of claim 2 , wherein the transmission control plate has at least one first functional element, which is arranged with its outer edge in the first recess, at least in some regions, and whereof the inner width of the through-flow opening of the first functional element is smaller than the inner width of the through-flow opening in the carrier layer, such that the holding region of the spring element is arranged between the first functional element and the carrier layer, at least in some regions, wherein, in the closed state of the through-flow opening, the spring plate is seated on a region of the first functional element which borders the circumferential edge of the through-flow opening of the first functional element.

4. The transmission control device of claim 3 , wherein the transmission control plate has a first functional layer arranged adjacent to a first side of the carrier layer, wherein the holding region of the spring element is arranged in the first recess between the carrier layer and the first functional layer, at least in some regions.

5. The transmission control device of claim 4 , wherein the carrier layer has, on a second side opposite the first side, along a circumferential edge of the through-flow opening, a step-shaped second recess which is set back from the through-flow opening.

6. The transmission control device of claim 5 , wherein a region bordering the circumferential edge of the through-flow opening in the respective layer and/or in the respective functional element has a flange, a metal ring, a rubber element, a half bead, a full bead or a corrugated profile as a seat for the spring plate or, in its outer edge region, extending circumferentially at least in some regions, the spring plate has a flange, a metal ring, a rubber element, a half bead, a full bead or a corrugated profile as a seat in the closed state of the through-flow opening.

7. The transmission control device of claim 5 , wherein the transmission control plate has at least one second functional element which is arranged with its outer edge in the second recess, at least in some regions.

8. The transmission control device of claim 7 , wherein a second functional layer is arranged adjacent to the second side of the carrier layer.

9. The transmission control device of claim 8 , wherein the second functional element and/or the second functional layer have a through-flow opening with an inner width smaller than the inner width of the through-flow opening in the carrier layer, such that, in the closed state of the through-flow opening, the spring plate is seated on a region bordering the circumferential edge of the through-flow opening.

10. The transmission control device of claim 8 , wherein, between the holding region and the spring plate and circumferentially around the spring plate, the spring element is pre-tensioned and/or angled in the direction of the second functional element and/or in the direction of the second functional layer.

11. The transmission control device of claim 8 , wherein the second functional element and/or the second functional layer have flow guiding elements, which, in the orthogonal projection of the transmission control plate, are arranged in the through-flow opening in the second functional element or the second functional layer and which are constructed such that they set a fluid flowing along the flow axis of the through-flow opening into rotational motion about this longitudinal axis.

12. The transmission control device of claim 8 , wherein at least one pair, a plurality of pairs or all pairs of adjacent connecting points are arranged offset from one another along the circumferential edge through at least 85° relative to the center of the connecting points.

13. The transmission control device of claim 8 , wherein at least one of the layers of the transmission control device and/or at least one of the functional elements of the transmission control device has at least one travel delimiting element for delimiting the travel of the spring plate, which has at least two webs which, in a projection of the transmission control plate perpendicularly to its planar extent, jut into the through-flow opening in the respective layer and/or in the respective functional element, wherein at least two of the webs are connected to one another at their ends which are opposite the circumferential edge of the through-flow opening and/or advantageously form a common web spanning the through-flow opening or a star having three or more web elements, wherein one or more webs or a star have a through-flow opening.

14. The transmission control device of claim 8 , wherein at least one travel delimiting element has at least one web which juts into the through-flow opening, wherein the at least one web is connected in one piece to the circumferential edge of the through-flow opening in the respective layer and/or in the respective functional element over at least 25° of the circular circumference of the
