Abstract

A tire pressure control system for a vehicle for determining tire-specific parameters, includes a valve body with a mounting portion, at least one mounting element and a tire pressure sensor with a housing, which has a mounting area. The mounting portion is detachably engaged via a mounting element with the mounting area of the housing. The tire pressure control system can be mounted in an easy, compact, cost-effective and simple way in that the mounting element is integrally formed with the housing of the tire pressure sensor.

First claim

The invention claimed is:

1. A tire pressure control system for a vehicle for determining tire-specific parameters, which comprises a valve body, at least one mounting element and a tire pressure sensor with a housing, which houses a sensor for determining at least one tire-specific parameter and for wireless transmission of the at least one tire-specific parameter to an on-board control device,
wherein the housing has a mounting area and the valve body comprises a mounting portion, and
wherein a mounting element detachably engages the mounting portion of the valve body with the mounting area of the housing,
wherein the mounting element is formed integrally with the housing of the tire pressure sensor.

2. A tire pressure control system according to claim 1 , wherein the mounting portion of the valve body includes an oblique surface, which is integrally molded on the circumferential surface of the valve body and over which the flexibly mounted mounting element can be moved when mounting the valve body to the tire pressure sensor in order to engage the mounting portion of the valve body with the mounting element of the housing.

3. A tire pressure control system according to claim 1 , wherein the mounting element has at least one snap-in hook which, when the valve body is mounted, extends in its longitudinal direction.

4. A tire pressure control system according to claim 3 , wherein the at least one snap-in hook of the mounting element engages in a recess designed at the mounting portion of the valve body when the valve body has been attached to the tire pressure sensor.

5. A tire pressure control system according to claim 3 , wherein the at least one snap-in hook of the mounting element engages in a flange integrally molded at the mounting portion of the valve body when the valve body has been attached to the tire pressure sensor.

6. A tire pressure control system according to claim 3 , wherein the at least one snap-in hook is retained at the mounting area and is adapted to be moved in relation to the housing via at least one resiliently malleable support arm.

7. A tire pressure control system according to claim 6 , wherein the at least one support arm extends transverse to the longitudinal direction of the mounted valve body, wherein the at least one support arm is designed in the form of a torsion bar, via which the at least one snap-in hook is adapted to be disengaged from the mounting portion of the valve body by being swiveled about the rotational axis of the at least one support arm.

8. A tire pressure control system according to claim 6 , wherein the at least one support arm extends parallel to the longitudinal direction of the mounted valve body, wherein the at least one support arm is supported at its longitudinal end facing away from the snap-in hook at the housing and is designed in the manner of a spring arm which, in a swivel movement pointing away from the longitudinal direction of the valve body, disengages the at least one snap-in hook from the valve body.

9. A tire pressure control system according to claim 8 , wherein the at least one snap-in hook is designed in the form of a U-shaped clamp that is adapted to be swiveled in a flexible manner which, when the valve body has been mounted to the tire pressure sensor, is overlapping a mounting lug, which is integrally molded to the mounting portion of the valve body.

10. A tire pressure control system according to claim 2 , wherein the mounting element has a cover-shaped clamp cap, which is connected with the housing via a film hinge, wherein the mounting area of the housing is designed in the form of a box and, after the valve body has been mounted to the tire pressure sensor, the clamp cap is releasably attached at the box-shaped mounting area and engaged with the mounting portion of the valve body.

11. A tire pressure control system according to claim 10 , wherein the box-shaped mounting area of the housing has at least one clamping bar, which extends in longitudinal direction transverse to the mounted valve body, and at least one clamping recess is designed in the clamp cap in complementary fashion to the at least one clamping bar, wherein via a clamp connection which, after mounting the clamp cap to the mounting area, is formed at the mounting area by the clamping bar clamped in the at least one clamping recess, the clamp cap is attached to the housing in such a way that the mounting portion of the valve body is locked.

12. A tire pressure control system according to claim 10 , wherein a clamping lug which, when the valve body has been mounted, extends from the clamp cap transverse to the longitudinal direction of the valve body, engages behind a projection, which is integrally molded to the mounting portion of the valve body, in such a way that it blocks a movement of the valve body in its longitudinal direction away from the housing.

13. A tire pressure control system according to claim 1 , wherein the mounting portion of the valve body has a bevel at least in sections, and the mounting area of the housing has a receptacle designed in complementary fashion to the bevel so that, when mounting the valve body to the tire pressure sensor, the mounting portion of the valve body is inserted in a torsion-proof manner in the receptacle.

14. A tire pressure control system according to claim 2 , wherein the mounting element has at least one snap-in hook which, when the valve body is mounted, extends in its longitudinal direction.

15. A tire pressure control system according to claim 4 , wherein the at least one snap-in hook is retained at the mounting area and is adapted to be moved in relation to the housing via at least one resiliently malleable support arm.

16. A tire pressure control system according to claim 5 , wherein the at least one snap-in hook is retained at the mounting area and is adapted to be moved in relation to the housing via at least one resiliently malleable support arm.

17. A tire pressure control system according to claim 11 , wherein a clamping lug which, when the valve body has been mounted, extends from the clamp cap transverse to the longitudinal direction of the valve body, engages behind a projection, which is integrally molded to the mounting portion of the valve body, in such a way that it blocks a movement of the valve body in its longitudinal direction away from the housing.
