Problems solved by technology

This buildup can adversely affect the sensor assembly if this fluid is allowed to enter the pressure inlet hole of the sensor assembly when the wheel is in the 12 o'clock or 6 o'clock positions
If this fluid is allowed to come into contact with the electronics, the sensor element itself may be permanently damaged

Embodiment Construction

[0014] Description of the preferred embodiment

[0015] Referring now to Figure 1 and figure 2 , which is a diagram of a tire pressure monitoring system 10 according to the present invention. The tire pressure monitoring system 10 is envisioned for use with motor vehicles, although various tire-based applications may be apparent in light of this disclosure. The tire pressure monitoring system 10 is intended to be mounted within a rim 12 having a rim inner surface 14 and a rim axis of rotation 16 (see FIG. 6 ). Although a variety of processes may be used to mount the tire pressure monitoring system 10 to the rim 12, it is preferably contemplated that the system 10 may be mounted using a band attachment process.

[0016] The tire pressure monitoring system 10 includes a sensor housing 18 having an arcuate configuration adapted to engage the inner surface 14 of the rim. The sensor housing 18 is preferably molded to produce a housing upper surface 20 , a first housing end surfa...

Abstract

A tire pressure monitor system is provided including a sensor housing forming an internal housing mount chamber. An air inlet port is formed on a housing side surface and is orientated parallel to the wheel rim rotational axis. A sensor assembly including an air pressure sensor element is mounted within the internal housing mount chamber. A filter element and a gasket element are positioned between the air pressure sensor element and the air inlet port. A potting material fills the internal housing mount chamber. The filter element and the gasket element creating an air pressure flow path from the air inlet port to the air pressure sensor element.

Description

technical field [0001] The present invention relates generally to a tire pressure monitoring system, and more particularly to a tire pressure monitoring system with a side entry pressure port for moisture ingress protection. Background of the invention [0002] Motor vehicles have been designed and manufactured to incorporate an increasing number of consumer and performance characteristics. These characteristics provide a range of information about vehicle performance and functionality. Whereas many of these systems were traditionally either implemented by hand or required a physical wire connection to the vehicle computer, many more systems within the vehicle now operate via wireless transmission. [0003] One feature that presents considerable challenges involves the monitoring of vehicle tire pressure. Correct tire pressure is essential as it affects vehicle handling, fuel economy, tire wear and more. To properly monitor tire pressure, the system is usually installed i...
