Embodiment Construction

[0017] figure 1 The housing 1 containing the wheel electronics and located in the region of the rim well 8 in the pneumatic tire is shown. The snap-in valve 2 is located in the rim 3 such that a valve base 4 , which is located in the region of the rim 3 and extends into a tire not explicitly shown, is detachably connected to the housing 1 via a fastening element 6 . The snap-in valve 2 or its valve axis 5 forms an angle α with the fastening element 6 . The angle α depends on the geometry of the rim and can form variations depending on the type of rim. The rotation lock ensures that the valve base can be inserted exactly into the housing 1, so that the fastening element 6, which in this embodiment is designed as a pin 6, can be screwed into a thread 10 formed in the valve base 4 to form a detachable connect. The ventilation takes place in this embodiment via the air intake 9 positioned substantially perpendicular to the valve axis 5 .

Abstract

The invention relates to a device for measuring tire pressure in a pneumatic tire of a vehicle, by means of a sensor on the rim well (8) of a rim (3) receiving a tire valve (2) for the pneumatic tire, tire pressure being applied to the sensor, and a receiver outside the pneumatic tire being assigned to the sensor. An electronics housing or signal housing (1) is attached to the rim well (8) and connected to the tire valve (2), said housing containing a transmitter as sensor for the tire pressure and being connected to the tire valve (2) by a fastening element (6) substantially in the area of the valve foot part (4).

Description

technical field [0001] The present invention relates to a device for measuring tire pressure in a pneumatic tire of a motor vehicle using a sensor on the rim well of the rim housing the tire valve of the pneumatic tire and a receiver provided to the sensor outside the pneumatic tire, the tire pressure being applied On this sensor, the electronics housing or the signal housing, which is arranged in the rim well, is connected to the tire valve, containing the transmission electronics as a tire pressure sensor, and via a tight The fixing element is connected to the tire valve. Background technique [0002] DE 37 34 053 A1 discloses a device for measuring the tire pressure in a pneumatic tire of a motor vehicle; a bellows is situated in the pneumatic tire in a direction approximately axially parallel to the direction of motion and is connected externally to the On a permanent magnet displaceable in an axially parallel manner depending on tire pressure, the measurable position o...
