Tire pressure control system
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.
1. A tire pressure control system, comprising
a tire valve and
a wheel electronic system which contains a pressure measuring device and a transmission device in a housing,
wherein the housing has on a bottom side two foot elements for placing onto a rim well of a wheel and has, on a rear side, a contact surface for seating on a tire valve base, said contact surface having an elongated hole for enabling the tire valve to project therethrough,
wherein
the contact surface being linearly displaceable on the valve base in the direction of the elongated hole during installation thereby enabling the system to be adjusted to a geometric condition of a given wheel without the use of separate attached components.
2. The tire pressure control system according to claim 1 , wherein an imaginary line of the contact surface is straight, said imaginary line intersecting an imaginary sectional plane extending in parallel to the elongated hole.
3. The tire pressure control system according to claim 1 , wherein the contact surface is flat.
4. The tire pressure control system according to claim 1 , wherein the tire valve comprises a hollow screw which is inserted into the valve base and projects through the elongated hole.
5. The tire pressure control system according to claim 1 , wherein the contact surface of the wheel electronic system is seated on a bearing surface of the valve base, said bearing surface being inclined in relation to the bottom side of the housing of the wheel electronic system in assembled condition.
6. The tire pressure control system according to claim 5 , wherein in assembled condition an imaginary intersecting line of the bearing surface and an imaginary sectional plane extending in parallel to the elongated hole is straight.
7. The tire pressure control system according to claim 5 , wherein the bearing surface is planar.
8. The tire pressure control system according to claim 1 , wherein the foot elements are formed as ribs.
9. The tire pressure control system according to claim 1 , wherein the foot elements extend along opposite longitudinal sides of the housing.
10. The tire pressure control system according to claim 1 , wherein the elongated hole is arranged in a plate-shaped section of the rear side of the housing.
11. The tire pressure control system according to claim 1 , wherein the contact surface is inclined in relation to the bottom side of the housing.
12. The tire pressure control system according to claim 1 further comprising a wheel having a rim well and wherein the foot elements of the wheel electronic system rest on the rim well with a section extending along the longitudinal sides of the housing.
13. A wheel electronic system comprising:
a housing; and
a pressure measuring device and a transmission device arranged in said housing, wherein the housing has on a bottom side two foot elements displaceable onto a rim well of a wheel and on a rear side a flat contact surface with an elongated hole displaceable onto a valve base thereby enabling the system to be adjusted to a geometric condition of a given wheel without the use of separate attachment components.
14. The tire pressure control system according to claim 1 wherein the tire valve includes a valve base with a flat bearing surface for the wheel electronic system.
