发明名称 Method for automatically monitoring the tyre pressure in the pneumatic wheels of a vehicle when travelling and when stationary, and pressure monitor for carrying out the method
摘要 The invention relates to a method and a pressure monitor for automatically monitoring the tyre pressure in pneumatic wheels of a vehicle when travelling and when stationary, in which deviation of the tyre pressure from the desired pressure is detected by means of a pressure switch located in the rim base. The pressure switch is part of a circuit which is arranged in the rim base and consists of a signal generator, a solid-borne sound transmitter connected downstream thereof and a battery which provides the power. If the desired pressure is no longer maintained, the solid-borne sound transmitter is caused by the signal generator to output an ultrasonic signal which is directed via an acoustic coupling as solid-borne sound into the rim and from there via solid-borne sound bridges of the wheel bearing into the chassis and is received by a solid-borne sound receiver arranged thereon and passed on in an evaluation and warning device which outputs a visual and/or acoustic signal.
