Definitions
- the present invention relates to a tire valve for insertion into a rim, more particularly according to the preamble of claim 1.
- Tire valves for pneumatic tires in particular motor vehicles such as
- Tire valve against the rim in which it is used, but that holds the tire valve captive or positive fit in the rim and limits even at high rotational speeds of the rim moving the tire valve in the rim.
- Such tire valves are also referred to as snap-in valves.
- other valves according to another embodiment of the present disclosure
- Invention are to be detected, inserted from one side into the rim until the rim encloses a sleeve-shaped seal on a valve sleeve without forming an undercut, and then a screw (nut), optionally with the interposition of a washer from the other side to an external thread the valve sleeve screwed until the sleeve rests against the seal or this pressed, see for example DE 200 15 467 Ul.
- Snap-in valves come due to a limited in the longitudinal direction on both sides by a radial projection recess to form an undercut, in which the rim dips with its edge or its Lochleibung, without external thread on the valve sleeve for screwing a counter element, such as such Screw sleeve, off.
- US 2008/0083272 A1 describes a tire valve with a reduced diameter at its axial end valve sleeve to allow an air space between the valve sleeve and a deferred seal.
- FR 2 947 214 AI also describes a valve sleeve reduced in diameter at its axial end to provide an air space within the enclosing air
- valve sleeve according to US 2010/0171361 AI is increasingly reduced in diameter at its axial end.
- the present invention has for its object to provide a tire valve for insertion into a rim of the type mentioned, whose
- the truck / utility vehicle has a valve sleeve with an air inlet end and an air outlet end opposite the air inlet end. Furthermore, an applied on the valve sleeve, in particular vulcanized elastic seal is provided, wherein the seal in the direction of the longitudinal axis of the valve sleeve from a first position, which faces the air inlet end or associated, to a second position, which faces the air outlet end or associated , extends.
- valve sleeve now has, in the region of the second position, that is to say in the region of the axial end facing the air outlet end of the elastic seal, a recess which extends partially or completely over the circumference of the valve sleeve in its outer one from the elastic
- the recess may for example have a depth of at least one-third or half or three-quarters of the wall thickness of the valve sleeve in the axial direction in front of the recess, in particular immediately in front of the recess. Furthermore, it can be provided that the recess by a displacement of the inner
- valve sleeve Surface of the valve sleeve relative to the inner surface of the valve sleeve in the portion which adjoins the recess in the direction of the first position, is achieved. This means that in the axial direction next to the recess, an inner shoulder or projection is provided in the inner surface of the valve sleeve. In the latter case, the recess may even have a depth which corresponds almost or completely to the wall thickness of the valve sleeve in front of the recess, or even a depth beyond it.
- an embodiment of the invention provides that the recess extends only partially over the circumference of the valve sleeve. Additionally or alternatively, the recess may have a varying depth over the circumference. Furthermore, it is supplementary or according to an alternative embodiment of the invention possible that the recess is limited at its two axial ends in each case by a radial projection which extends at least partially over the circumference of the valve sleeve or completely over the circumference of the valve sleeve.
- the embodiment according to the invention makes it possible for the valve sleeve, which, for example, is held exclusively elastically by the elastic seal in the rim to be subject to displacement relative to the rim due to centrifugal forces during the rotation of the rim, within the elastic seal
- Valve sleeve carries at its end of the air outlet a tire pressure sensor or other mass device, this air outlet end of the valve sleeve of a significant displacement due to acting centrifugal forces
- any bulked device which is particularly releasably connected to the valve sleeve and which shifts the center of gravity of the combination of the valve sleeve and the bulked device significantly toward or beyond the air outlet end enhances the displacement problem.
- the invention is particularly advantageous in such tire valves with a comparatively large mass at the area of the air outlet end applicable.
- the elastic seal may have on its outer periphery according to an advantageous embodiment of the invention, a recess for receiving a bearing hole of the rim.
- the recess is advantageously positioned in the direction of the longitudinal axis of the valve sleeve partially or completely offset from the recess in the valve sleeve, so that the recess in the elastic seal the recess in the valve sleeve in an axial section through the tire valve seen only partially or not overlapped.
- the recess on the outer periphery of the elastic seal is provided completely adjacent to the recess in the valve sleeve, whereas in the former case there is a partial overlap, but on opposite sides of the elastic seal.
- the recess on the outer circumference of the elastic seal for receiving the hole of the tire valve enclosing portion of the rim at its two axial ends radially outwardly projecting protrusions to form an undercut when the tire valve in the hole used in the rim respectively
- the recess is limited only at one axial end by a radial projection. It is advantageous if the recess in the elastic seal in the direction of the longitudinal axis of the valve sleeve is limited at least at one of its axial ends or at both axial ends by a radially outwardly extending projection which forms an axial bearing surface for the rim.
- Such an axial abutment surface can also be provided by a corresponding projection at a distance from the radially outwardly facing surface on which the rim sits, that is, the axial abutment surface is formed by an axially extending projection on the radially outward
- the recess on the outer circumference of the valve sleeve has a greater axial length than the recess on the outer circumference of the elastic seal.
- the recess in the valve sleeve can be formed either by an air-filled space, that is, the radially inwardly directed surface the elastic seal is spaced from the bottom of the recess in the
- Valve sleeve positioned (at least in the non-displaced or, if the elastic seal during assembly in the rim radially inwardly deformed in the uninstalled state of the valve sleeve within the rim), or the
- Recess may be partially or completely filled with an elastic material.
- This elastic material may, according to one embodiment, be made softer than the elastic material of the seal. Alternatively, however, it is also possible that the material has the same rigidity as the elastic seal or even greater rigidity.
- the elastic material of the gasket and the elastic material in the recess are identical, but usually separate from each other.
- the boundary of the recess at both axial ends in each case by a radial projection which extends partially or completely over the circumference of the valve sleeve has proven to be advantageous.
- the elastic seal In order to produce an additional distance of the elastic seal in the region of the second position to the outer surface of the valve sleeve, the elastic seal on its inner, facing the valve sleeve, in particular on this adjacent surface having an inner recess which the recess in the radially outer surface of the Partially or completely opposite valve sleeve. It is advantageous if in this case the recess in the valve sleeve in the direction of the longitudinal axis of the valve sleeve over the entire
- both recesses inside the elastic seal may begin at the same position and the recess in the valve sleeve then extends toward the air outlet end via the axial end of the valve
- the inner recess can according to a
- Embodiment be designed as unilaterally open inner recess, that is it extends from the interior of the elastic seal to its axial end at the second position.
- the inner recess may advantageously have an undercut, in particular at its end facing away from the second position, in order to reduce notch effects if deformation of the elastic seal still occurs due to the application of the valve sleeve.
- the inner recess in the elastic seal and / or the recess on the outer circumference of the valve sleeve extend over the entire circumference of the elastic seal or the valve sleeve, but it is also a partial extension into consideration. It is also possible that one or both recesses described herein have a depth varying over the circumference.

- the valve sleeve 1 has an air inlet end 4 and an air outlet end 5 arranged opposite thereto.
- the air outlet end 5 is positioned inside a pneumatic tire (not shown), whereas the air inlet end 4 is positioned outside the pneumatic tire and accessible from the outside so that compressed air can be introduced into the pneumatic tire via the air inlet end 4 from the air outlet end 5.
- the air inlet end 4, as shown, usually has an external thread for receiving a screw cap.
- a channel for supplying compressed air into the pneumatic tire extends in the direction of the longitudinal axis of the valve sleeve 1 from the air inlet end 4, which is usually closed by a valve core, to the air outlet end 5 and out therefrom, for example through the illustrated radial bore 6
- Other forms of progression are possible.
- the valve sleeve 1 carries an air pressure sensor 7, which has an air pressure measuring device and a transmitting device, so that air pressures detected by the air pressure sensor 7 can be converted into a wireless signal and sent to a receiving device outside the pneumatic tire. Due to the positioning of the air pressure sensor 7 at the air outlet end 5 acts at high speeds of the rim 3, a significant centrifugal force on the
- valve sleeve 1 in the region of the axial end of the elastic seal 2, which faces the air outlet end 5 of the valve sleeve 1, a recess 9 in the enclosed by the elastic seal 2 outer surface.
- the recess extends 9 in the valve sleeve 1 from within the elastic seal 2 beyond its axial end at the second position 11 also.
- the elastic seal 2 in turn has on its outer periphery a
- Inner recess 13 which faces the recess 9, but only up to the second position 11, that extends to the axial end of the elastic seal 2 extends.
- the inner recess 13 has a relief groove 14, which improves the mountability.
- the elastic seal 2 has in the region of the recess 12 in an
- Axial direction projecting collar 15 which contributes to the system to the rim 3 and thus to seal the rim 3 against the elastic seal 2.
- the recess 9 has the same depth over the entire circumference of the valve sleeve 1. Furthermore, it is limited at both axial ends in each case by a radial projection 16, 17. However, this is not absolutely necessary. In particular, the radial projection 16, the the radial projection 16, the the
- Air outlet end 5 faces, omitted and instead the recess 9 could be only partially carried out over the circumference of the valve sleeve 1 and / or have a varying over the circumference of the valve sleeve 1 depth.
- the depth of the recess 9 varies over the circumference of the valve sleeve 1.
- the recess 9 could also be provided only over a portion of the circumference of the valve sleeve 1 be, namely in that peripheral portion which approximates to the inner circumference of the elastic seal 2 in a displacement of the valve sleeve 1 by the centrifugal force.
- Projection also extend over the entire circumference of the valve sleeve 1 with a constant height or varying height.
- an elastic material is introduced into the recess 9 in the embodiment according to FIG.
- This elastic material numbered 18 here, may extend over the entire recess 9, or, as shown, only over a portion thereof, in the circumferential direction and / or in the axial direction.
- the projection 16 can advantageously also extend over the entire circumference of the valve sleeve 1.
- the elastic seal 2 is shown again.
- the outer recess 12 forms an undercut, so that a secure fit in the mounted state in the rim is achieved.
- FIG. 4b again shows the valve sleeve 1 according to the embodiment of FIG.
- the recess 9 has at its one axial end, which faces the air inlet end 4, a radial projection 17 which extends over the entire circumference (variable height), whereas at the opposite end, which is associated with the air outlet 5, a radial Projection 16 which extends only over a portion of the circumference of the valve sleeve 1, namely that portion in which the recess 9 is made comparatively deeper.
