A pressure sensing assembly configured to be attached to a bicycle wheel having a tire and a rim mounted to the tire. The pressure sensing assembly includes a housing, a pressure transmitting member, a sensing chamber defined by the housing and the pressure transmitting member, and a sensing element. The pressure transmitting member is coupled the housing and has a central portion offset from the plane in a first direction. The sensing element is offset from the plane in a second direction opposite the first direction. The pressure transmitting member is configured to transmit a pressure in the tire to the sensing element via the sensing chamber.

A multi-functional TPMS sensor fastener torque tool includes a torque driver and a user interface which allows a user to identify the TPMS sensor to be serviced, obtain a recommended fastener torque from a reference torque value database, measure the torque applied to the sensor fastener and alert the user when the reference torque has been reached or exceeded. In one example, the reference TPMS fastener torque values are stored in a memory device in the torque tool which are accessible through a plurality of graphic user interface menus on a display device.

An air induction system for filtering a compressible fluid to an electromechanical component mounted on a wheel of a vehicle. The system may make use of a first plurality of float valves arranged in series in a non-linear first flowpath path, with at least one of the float valves forming an inlet for intaking the compressible fluid into the first flowpath, and one being in communication with an inlet of the electromechanical component. Each of the float valves may have a buoyant float valve element therein which is responsive to change position when submerged in water, to close off its respective float valve depending on an angular orientation of the wheel, and thus an angular orientation of the float valve.

In one aspect the present disclosure relates to an in-wheel tire pressure system for use with a rim of a wheel of a vehicle. The system may comprise a fluid storage area formed in the rim for holding a quantity of compressible fluid suitable for inflating a tire mounted on the rim, and a micro-compressor mounted on the rim for pressurizing the fluid storage area with the compressible fluid. A wireless electrical charging subsystem may also be included for powering the micro-compressor. The wireless electrical charging system may incorporate a first component associated with the rim and rotatable with the rim, and a second component fixedly mounted to a portion of the vehicle closely adjacent the first component. The system may also include a control for enabling user control over the micro-compressor.

A tool is configured to install a tire pressure monitoring (TPM) sensor in a tire rim of a vehicle tire. The tool includes a lever having a rotational movement about a rotational axis; a cam selectively coupled to the lever; and a push pin selectively coupled to the cam. The cam translates the rotational movement of the lever into a liner or translational movement of the push pin. The linear or translational movement is effective to impact or move a roll pin of a tire pressure monitoring (TPM) sensor disposed at the tool, such that portions of the TPM sensor or pushed through an opening in a tire rim.

The approach presented here relates to a monitoring device (100) for a vehicle. The monitoring device (100) has at least one measuring device (105) with a sensor unit (110) and a transmitter unit (115). The sensor unit (110) is designed to sense a physical parameter in the area of the wheel in a coupled position on a first section of a wheel hub (120) of a wheel of the vehicle while the vehicle is moving. The transmitter unit (115) has a fastening device which is shaped in order to fasten the transmitter unit (115) in a fastening position on a second section of the wheel hub (120) of the wheel or on a wheel rim (122), the transmitter unit (115) is designed to wirelessly send a sensor signal (125) representing the physical parameter to a warning device in order to enable monitoring of the physical parameter.

An apparatus for a single-track motor vehicle includes a first wheel disc and a second wheel disc. The first wheel disc and the second wheel disc are configured on the wheel rim so as to be mutually spaced apart in a transverse direction parallel to the rotation axis (A) of the disc wheel, and extend from the wheel rim in the direction of the wheel hub. The wheel discs converge in the direction of the wheel hub and are connected to one another in such a manner that at least one cavity between the wheel discs and the wheel rim is formed. At least one cutout toward the at least one cavity is formed in a rim well of the wheel rim.

A system for detecting liquid inside a wheel that includes a tire pressure valve, a power source, a circuit, and an indicator. The valve includes a stem, a valve mechanism, and one electrode with a first end segment with a first end and a second end segment with a second end of the electrode. The tire valve is fixed to the rim where the ends are positioned outside the rim and the central part is positioned between the rim and the inner side of the tire. The ends are connected to the power source and to the circuit that outputs a signal that reflects resistance between the ends that its magnitude is changed where no liquid covers the central part and where liquid covers a part of the central part. This magnitude indicates presence of liquid and the level of liquid inside the tire.
