Embodiment Construction

[0049] The electronic unit according to the invention shown exemplarily in the drawings is intended to be mounted on a wheel of a vehicle in order to measure operating parameters of said wheel (pressure, temperature, acceleration, etc.) The central unit (not shown) on the vehicle transmits.

[0050] These electronic units consist of an electronic module 1 adapted to be mounted inside the casing of a tire and an inflation valve for securing said electronic module in the wheel on which said tire is equipped. on the rim.

[0051] according to figure 1 and figure 2 First, the inflation valve 2 consists of a "snap-in" inflation valve comprising a valve body 3 made of elastomeric material axially provided with a cylindrical longitudinal hole 4 .

[0052] Traditionally, the valve body 3 is also longitudinally divided into a trunk 5 and a stop head 6, wherein the trunk has longitudinal and radial elastic deformation functions, and the stop head is connected to the trunk 5 through ...

Abstract

The invention relates to an electronic unit that includes an inflation valve (2) adapted to be connected to a rim (J) of a wheel and an electronic housing (1) assembled with said inflation valve. According to the invention, the inflation valve (2) comprises a rigid tube (12) extending away from said valve and having at least one transverse detent (20, 21) at the periphery thereof, while the electronic housing (1) is rigidly connected to a ring (15) slidably mounted around the rigid tube (12). Furthermore, a plate latch (22) having a locking tooth (24) adapted to be inserted into a transverse detent (20, 2) of the rigid tube (12) is mounted on the electronic housing (1) and is capable of moving between a locking position and an unlocking position, said latch plate being associated with elastic means (26) adapted for applying, in the absence of stress, a force for maintaining the latter in the locking position and, when an action is applied to said elastic means (26), for driving a movement of said plate latch (22) into the unlocking position thereof.

Description

technical field [0001] The invention relates to an electronic unit for measuring operating parameters of a wheel, comprising an electronic module and an inflation valve. Background technique [0002] More and more motor vehicles have parameter monitoring and / or measuring systems that include sensors. [0003] As such a system, by way of example, a tire pressure monitoring system may be cited comprising an electronic module mounted on each wheel of the vehicle, wherein said electronic module is dedicated to measuring parameters (for example: the pressure of the tires equipped with these wheels and / or temperature) and is used to notify the driver of any abnormal changes in the measured parameter. [0004] One of the currently most common solutions for fixing electronic modules on the wheel rim consists in manufacturing electronic units each consisting of electronic modules assembled together with inflation valves that allow the The electronic module is fixed on the rim of th...
