Abstract

A tire pressure control system includes a tire valve and wheel electronics including a pressure measuring device and a transmission device in a housing, wherein the housing has two base elements on a bottom for attaching the same to a rim well of a wheel, and a contact surface seated on a valve spud of the tire valve in the mounted state. The surface has an elongated hole through which the tire valve projects in the mounted state. The invention provides that the contact surface can be linearly displaced in the direction of the elongated hole on the valve spud during installation.

Claims

1. A tire pressure control system, comprising

a tire valve (1) and

a wheel electronic system (3) which contains a pressure measuring device (3b) and a transmission device (3c) in a housing (3a),

wherein the housing (3a) has on a bottom side two foot elements (3d) for placing onto a rim well (2a) of a wheel and has on a rear side a contact surface (3e) for seating on a valve base (1a) of the tire valve (1) in assembled condition, said contact surface (3e) having an elongated hole (4) through which the tire valve (1) projects in assembled condition,

characterized in that

the contact surface (3e) can be linearly displaced on the valve base (1a) in the direction of the elongated hole (4) during installation.

2. The tire pressure control system according to claim 1, characterized in that an imaginary line of the contact surface (3e) is straight, said imaginary line intersecting an imaginary sectional plane extending in parallel to the elongated hole (4).

3. The tire pressure control system according to any one of the preceding claims, characterized in that the contact surface (3e) is flat.

4. The tire pressure control system according to any one of the preceding claims, characterized in that the tire valve (1) comprises a hollow screw (1b) which is inserted into the valve base (1a) and projects through the elongated hole (4).

5. The tire pressure control system according to any one of the preceding claims, characterized in that the contact surface (3e) of the wheel electronic system (3) is seated on a bearing surface of the valve base (1a), said bearing surface being inclined in relation to the bottom side of the housing (3a) of the wheel electronic system (3) in assembled condition.

6. The tire pressure control system according to claim 5, characterized in that in assembled condition an imaginary intersecting line of the bearing surface and an imaginary sectional plane extending in parallel to the elongated hole (4) is straight.

7. The tire pressure control system according to claim 5 or 6, characterized in that the bearing surface is planar.

8. The tire pressure control system according to any one of the preceding claims, characterized in that the foot elements (3d) are formed as ribs.

9. The tire pressure control system according to any one of the preceding claims, characterized in that the foot elements (3d) extend along opposite longitudinal sides of the housing (3a).

10. The tire pressure control system according to any one of the preceding claims, characterized in that the elongated hole (4) is arranged in a plate-shaped section of the rear side of the housing.

11. The tire pressure control system according to any one of the preceding claims, characterized in that the contact surface (3e) is inclined in relation to the bottom side of the housing.

12. A wheel comprising a rim well and a tire pressure control system according to any one of the preceding claims, characterized in that the foot elements (3d) of the wheel electronic system rest on the rim well (2a) with a section extending along the longitudinal sides of the housing (3a).

13. A wheel electronic system comprising a housing (3a), with a pressure measuring device (3b) and a transmission device (3c) being arranged in said housing (3a), wherein the housing (3a) has on its bottom side two foot elements (3d) to be placed onto the rim well (2a) of a wheel and has on a rear side a contact surface (3e) with an elongated hole (4) to be placed onto the valve base (1a) of a tire valve (1), characterized in that the contact surface (3e) is flat.

14. A tire valve for a tire pressure control system, characterized by a valve base (1a) with a flat bearing surface for a wheel electronic system (3).
