In a vehicle wheel including a rim, a sub-air chamber member serving as a Helmholtz resonator, and a tire pressure sensor unit, the sub-air chamber member and the tire pressure sensor unit are integrated with each other to be mounted on the rim via an air valve. The tire pressure sensor unit is preferably integrated with the air valve. The vehicle wheel may be configured such that the sub-air chamber member is connected to the tire pressure sensor unit via a bracket, and the bracket is insert-molded in the sub-air chamber member. Moreover, an edge of the sub-air chamber member may be locked to a well part at an opposite side in a wheel width direction to the tire pressure sensor unit.

The disclosure relates to the field of automobile detection apparatus technologies, and provides a tire pressure sensor including: a sensor body, a valve assembly connected to the sensor body, a locking member, a resilient member, and a button; wherein a fixture block assembly is disposed at a connecting end of the valve assembly; the locking member is disposed within the sensor body, and the locking member limiting the fixture block assembly when the connecting end is inserted into the sensor body; the button is disposed within the sensor body, and when the button receives an external force, the button transmits an external force to the fixture block assembly, so that the locking member relieves limiting of the fixture block assembly. An entire process of installation and disassembly of the tire pressure sensor becomes simpler and faster.

A housing for an electronic module for an electronic unit for measuring operating parameters of the wheel of a vehicle which is able to collaborate with a snap-in type inflation valve, including a valve body made of an elastomer material, provided with a longitudinal axial bore and intended to extend through an orifice made in a rim, and a hollow tubular core made of a rigid material. A front face of the electronic module housing being connected to the inflation valve using a connecting device. The electronic module is configured to prevent the electronic module from pivoting about an axis defined by the housing connecting device.

A tire-pressure-monitoring system includes a flexible member including a stem and a bulb, a metal tube disposed coaxially in the stem, an attachment member, and a sensor housing fixed to the attachment member. The bulb includes an outer circumferential surface including a groove. The attachment member is adjacent the outer circumferential surface and includes a rib positioned in the groove.

A tire monitoring apparatus comprises a sensor housing having a connection part integrated with the sensor housing, the connection part having an elongated opening and a corresponding mounting feature in a wheel rim, wherein a screw extends through the elongated opening and connects with the corresponding mounting feature in the wheel rim, thereby when the screw is not tightened fully, the sensor housing can be rotated with respect to the corresponding mounting feature in the wheel rim, and when the screw is tightened fully, the sensor housing is secured in place and does not rotate with respect to the corresponding mounting feature in the wheel rim.

A valve stem sytem includes a valve stem that is fluidly coupled to a tire thereby facilitating the valve stem to selectively inflate and deflate the tire. A sensing unit is coupled to the valve stem and the sensing unit is visible on the valve stem. The sensing unit is in fluid communication with the valve stem to sense air pressure within the tire thereby facilitating the sensing unit to display the air pressure within the tire. A valve stem assembly includes a pressure sensing body and a valve core configured to threadedly engage the tire stem and regulate air flow from a tire. The pressure sensing body includes plunger that responds to pressure fluctuations in the tire and provides a continuous measurement of air pressure.

A comprehensive tire pressure maintenance system for use with motor vehicles that includes a TPMS with an externally mounted battery, tubular battery configured for deployment on a valve stem configured to accommodate deployment of the tubular battery, a self-inflating pressure-optimizing tire arrangement, and a self-inflating run-flat tire arrangement and a wireless tire pressure gauge.

Adapter, tyre parameter monitoring system and method for mounting a tyre parameter monitoring system onto a wheel rim In an embodiment, a tyre parameter monitoring system (2) is provided that comprises an electronic module (4) with a fitting (6) for a snap-in valve, a ball stud (8) coupled to the fitting (6) and a valve stem (10) for a clamp-in valve. The valve stem (10) has a ball socket (12) that is coupled to the ball stud (8) for form a ball joint such that the valve stem (10) is positionable at different angles to the electronic module (4).

A tire pressure sensor attached to an air valve includes a body and two wings. The body has a face located between the two wings. The wings have ridges extending from the face, in a gradually expanding curved arc, to form an enlarged end. The ridges and the face together form a groove therebetween. An air valve includes a tube, a nut and a connector which is connected to one end of the tube. The nut is threaded onto the tube. The connector has end portions extending from two ends thereof. The connecting portion of the connector is engaged with the groove, and the protrusions abut against the inside of the ridges. The nut is rotated to drive the tube, and the connector presses the protrusions to contact against the ridges. This achieves a one-time lock attachment in a single step, offering improved functionality.

A packaging method for a tire pressure monitoring sensor includes a step of placing, a step of pouring, and a step of hardening. In the step of placing, a sensing transmission module is put into a cavity of a modeling unit, and a positioning portion in the cavity restricts the sensing transmission module from moving transversely and toward an inner bottom of the cavity. In the step of pouring, a rubber compound is poured into the cavity and fills the cavity. The sensing transmission module is coated by the rubber compound to form a case on the outer surface of the sensing transmission module. In the step of hardening, the case is hardened and integrally formed with the sensing transmission module to form a tire pressure monitoring sensor which is removed from the cavity.
