An apparatus for tire pressure monitoring comprises a case, a gas nozzle unit movably connected to the outside of the case, and a structure for tire pressure monitoring which is received in a receiving space in the case. The structure for tire pressure monitoring comprises a main body, a signal processing unit, a sensing unit connected to the signal processing unit, and a power unit to provide power. The main body has a first part and a second part. The first part is disposed on a top side of the second part; the first and the second parts are not on the same plane. The signal processing unit and the sensing unit are disposed on one side of the first part and on the top side of the second part, respectively. The power unit is disposed on a bottom side of the second part.

A heat protection device for a wheel electronics unit on a rim of a wheel of a vehicle, having a main body with a fastening portion for fastening to the wheel electronics unit, and at least one heat protection portion for thermally insulating the wheel electronics unit in the fastened position.

A tyre pressure sensor is mounted at the distal end of a valve stem mounted on a wheel. A protective assembly comprises a body which is releasably attached to the wheel, and a cap which is releasably attached to the body. The valve stem and pressure sensor are enclosed within the body and the cap.

The tire inflation valve comprising a tube defining a passage and having an inside end and an outside end, a valve mechanism positioned in the passage, the valve mechanism comprising a valve shutter and a seat arranged so as to cooperate sealingly with each other, the seat being arranged on the tube in the passage.

An electronic unit that is intended to be mounted on the valve of a vehicle wheel fitted with a tire, incorporating electronics for monitoring at least one operating parameter of the wheel and a rechargeable power supply for supplying power to the electronics, including a device for charging the rechargeable power supply, the device for charging including: a movable element, at least a portion of which is magnetized, that is capable of being set in motion by an air flow for inflating the tire that passes through the valve and cooperating with a coil so as to produce variations in the magnetic field and electromagnetic induction; and a device for managing the charging of the rechargeable power supply.

An electronic unit for measuring operating parameters of a vehicle wheel, including an electronic casing; an inflation valve; and elements for attaching the electronic casing and the inflation valve. The elements for attaching the electronic casing and the inflation valve include an insert provided with an axial bore and mounted with the ability to pivot in the continuation of the body of the inflation valve; a sleeve secured to the electronic casing, designed to be mounted with the ability to slide around the insert, a way of assembling the sleeve of the electronic casing and the insert of the valve body; and a spring-effect elastic.

A tire monitoring system with mounting features on a housing provide for positioning through a wide range of angles. Accordingly, the system can be positioned on an a variety of wheel rim/valve combinations. The tire monitoring apparatus includes two opposed wings provided on the housing to facilitate the range of positioning angles at which the housing can be positioned with respect to a valve base. Each opposed wing has a same exterior surface radius of curvature and the wings are clamped between a base plate and a clamp plate at the desired angle.
