Definitions
- Shaft-hub connection in particular a shift fork unit, and method for producing such a shaft-hub connection
- the present invention relates to a shaft-hub connection with the features of the preamble of claim 1, in particular for use in shift forks in manual transmissions.
- the invention further relates to a method for producing such a shaft-hub connection with the features of the preamble of claim 12.
- sleeves or hubs For gearboxes, sleeves or hubs must be fixed on shafts in many places. These sleeves should not move or twist relative to the shaft in certain applications. Currently sleeves are generally used, which are pushed onto the shaft and pressed with this. To achieve additional security, both components can then be drilled together. This ensures that the drill holes are exactly on top of each other. Through the hole, a spiral clamping pin is pressed in, which prevents slippage of the components against each other. The described operation is complex and therefore expensive. It is a spiral pin required as an additional component. In addition, there is a risk that can be pulled while pinning a chip. If this is not noticed and remains easily releasably attached to the module, such a chip can easily get into the transmission and lead to significant transmission damage.
- the compound described in the present application is particularly suitable for use as a shaft-hub connection in shift forks of vehicle transmissions.
- shift forks are shown for example in DE 101 59 441 A1 and DE 103 09 407 A1.
- DE 103 09 407 A1 describes a shift fork with a fork-shaped body and with a guide. In this guide, a switching element, such as a shift rod or a sliding or rolling bearings is introduced.
- a primary object of the invention is to produce a simple, stable and inexpensive connection between a shaft, in particular a shaft in the shift fork assembly of a vehicle transmission, and a sleeve or hub, which prevents slippage of the components against each other.
- a first embodiment of a shaft according to the invention has in its outer circumferential surface at least one recess.
- the hub or sleeve used has in its inner circumferential surface on a corresponding portion which engages in the recess on the outer circumferential surface of the shaft.
- the section in the inner surface of the hub is plastically deformed and can be further deformed by a further step, so that it optimally adapts to the depression. This can be done for example by caulking. In this way, an optimally secured against loosening or twisting positive and non-positive connection of the sleeve or hub on the shaft is achieved, so that even large forces and torques can be transmitted easily.
- the shaft has at least one elevation in its outer circumferential surface.
- the hub or sleeve used contains in its inner circumferential surface a corresponding recess into which the Increasing the outer circumferential surface of the shaft engages.
- a hollow shaft is preferably used in order to achieve from the inside a plastic deformation and thus a positive connection of the two parts can.
- the plastic deformation can take place, for example, by pressure forming with the aid of a pressure fluid.
- the shaft-hub connection described here is used in particular on a shift fork unit of a vehicle transmission.
- the compound includes corresponding recesses or projections on the mutually engaged radial inner lateral surfaces of a hub or sleeve and outer circumferential surfaces of a shaft.
- the at least one projection, which engages in the corresponding recess, is plastically deformed.
- the hub includes at least one recess on the inner circumferential surface and the shaft at least one projection on the outer circumferential surface.
- the hub has a plurality of depressions and the outer circumferential surface of the shaft has the same number of projections.
- a plurality of projections on the inner circumferential surface of the hub or sleeve and a plurality of corresponding recesses may be provided on the outer circumferential surface of the shaft.
- the hub or sleeve is pressed over its circumference with the shaft.
- the hub or sleeve can be glued over its circumference with the shaft and / or be connected cohesively.
- any method known to the person skilled in the art for producing a cohesive connection can be used.
- the depressions on the outer lateral surface of the shaft or on the inner lateral surface of the hub or sleeve can be introduced, for example, by means of a metal-cutting process. In this way, almost any contours can be formed. Then it makes sense to deburr the parts. This is especially important to prevent chips from getting into the gearbox and resulting in significant consequential damage.
- the recesses can be mounted in the form of one or more holes on the outer circumferential surface of the shaft.
- the fixed connection with the correspondingly shaped hub or sleeve can be made by pressure forming.
- the protrusions or webs arranged on the inner lateral surface are thereby pressed in a form-fitting manner into the corresponding recesses on the outer lateral surface of the shaft by plastic deformation.
- connection between at least one cleared and / or abutted depression is produced on the inner lateral surface of the sleeve or hub and a pressure-formed hollow shaft.
- the pressure-shaped hollow shaft contains projections or webs arranged on the outer lateral surface. These projections are pressed by plastic deformation in a form-fitting manner into the corresponding recesses on the inner surface of the hub or sleeve.
- a particularly simple and inexpensive to manufacture variant of the invention may also provide that in the hub or sleeve, a through hole or more through holes are introduced, which are usefully oriented at an angle of about 90 degrees to the sleeve axis.
- the through holes can also be arranged obliquely to this axis, which may be useful for space reasons.
- the hollow shaft material is pressed into the inner sections of these holes, wherein the hollow shaft is plastically deformed in these areas.
- the webs or projections of the shaft produced thereby form a positive connection with the hub or sleeve, so that a torsion-proof and highly loadable shaft-hub connection is achieved. create is.
- the forming process takes place, for example, by means of hydraulic pressure in a high-pressure forming process.
- the shaft-hub connection is used in particular in a shift fork unit of a vehicle transmission and has corresponding recesses or projections on the mutually engaged radial inner lateral surfaces of a hub or sleeve and outer circumferential surfaces of a shaft.
- the at least one projection is pressed by plastic deformation into the corresponding recess.
- the hub or sleeve can be pressed over its circumference with the shaft, glued and / or otherwise connected cohesively.
- the depressions on the outer lateral surface of the shaft or on the inner lateral surface of the hub or sleeve can be introduced optionally by means of a metal-removing process or by chipless production processes.
- a pressure-formed hub or sleeve which contains arranged on its inner lateral surface projections or webs. These are pressed by plastic deformation positively into the corresponding recesses on the outer circumferential surface of the shaft.
- a pressure-shaped hollow shaft is used, whose protrusions or webs arranged on the outer lateral surface are pressed into the corresponding depressions on the inner lateral surface of the hub or sleeve by plastic deformation in a form-fitting manner.
- the connection of a single recess and a single corresponding projection can be used.
- the hub preferably has at least two recesses or protrusions and the shaft also has at least two corresponding protrusions or recesses on.
- These at least two connecting elements can be arranged so that they are respectively arranged opposite one another on the shaft or hub.
- the depression does not have to be in the form of a (through) bore. It is also a blind hole or a corresponding, non-continuous material recess possible, in which engages the corresponding increase. In this case, recesses and corresponding projections are also possible, which extend over the entire circumference of the shaft and hub, so that the connection is produced at the connection point over the entire circumference of the shaft - in an annular manner.
- the invention relates firstly to the compound per se and secondly to the process for the preparation of this compound.
- Fig. 1 shows a shift fork unit with a guide for a shaft in which the shaft and the guide are connected to each other according to the invention
- Fig. 2 shows a cross-sectional view in which was cut through the guide
- Fig. 3 shows a detail of the enlarged cross-sectional view.
- FIG. 1 shows the structure of a shift fork unit. This consists of a fork-shaped main body 20 and a guide 14.
- the basic body 20 is made for example of sheet metal or other dimensionally stable material. It can also be a cast component.
- the guide 14 is a sleeve or hub and has a guide hole in which a shaft 12 is guided. Furthermore, the guide 14 has a recess 16 on its outer surface and a projection 15 (see Fig. 2) at a corresponding position of the inner surface.
- the shift fork 20 also has sliding shoes 22 at both fork ends. These are for example made of plastic and are plugged or fitted.
- FIG. 2 and 3 illustrate the connection between see sleeve 14 and shaft 12.
- the shaft 12 has in the illustrated embodiment, two oppositely arranged holes 13, which are each formed as blind holes.
- the elevations 15 already described above within the inner circumferential surface of the sleeve 14 each engage in the bores 13. These holes 13 are deburred and / or chamfered, so that any remaining drilling chips can not hinder the intervention.
- connection is made by first pushing the undeformed sleeve 14 over the shaft 12 and bringing it into the correct position. After the sleeve 14 is properly positioned, the opposite recesses 16 are pressed on the outside of the sleeve, whereby the material begins to flow and by plastic deformation referred to as elevations 15 pin on the inner circumferential surface of the sleeve 14 in the corresponding recesses or holes 13 are pressed against the outer circumferential surface of the shaft 12.
- a kinematic reversal of the described connection type can also take place (not shown) by using a hollow shaft which is connected by pressure forming to a hub or sleeve which has recesses which have been cleared or pushed on its inner lateral surface. In these depressions webs or elevations are pressed on the outer circumferential surface of the shaft by means of plastic deformation.
- the invention is not limited to the above embodiments. Rather, a variety of variants and modifications are conceivable that make use of the inventive concept and therefore also fall within the scope.
