Abstract
The invention comprises a tire pressure monitoring system. One system comprises a tire pressure monitor that signals to a user with audio alarm and visual alarm. Another component is the use of a tire air pressure balancing device with a safety trigger to ensure that dual tire systems share air but that stop sharing air in the case of rapid air pressure drop as in cases of tire blow out.
Claims9
A tire pressure monitoring system comprising a tire pressure sensor and a transmitter for sending an RF signal to a receiver when a tire pressure drops below a predefined pressure differential;
- the tire pressure sensor is mounted on an axle or an axle hub more than ten centimeters from a valve stem on a tire;
- and wherein the tire pressure sensor is insensitive to changes in ambient air temperature surrounding the tire, and when ambient temperature drops, both the predefined pressure differential in a pressure chamber of the tire and the tire pressure drop equally.
A tire pressure monitoring system comprising the tire pressure sensor, a tire pressure sharing channel and a transmitter for sending an RF signal to a receiver when a tire pressure drops below a predefined pressure differential and a safety trigger wherein the tire pressure drops below a lower predefined pressure the safety trigger stops air from flowing in the channel.
