Embodiment Construction

[0029] The techniques described in this application provide examples, and are not intended to limit the scope, applicability, or configuration of the invention. Rather, the following description will provide those skilled in the art with an enabling description for implementing the embodiment. Many changes may be made in function and arrangement of elements.

[0030] refer to figure 1 , one application of the exemplary embodiment relatively depicts a truck 20 having a tractor 24 and a trailer 28 . Such as figure 1The trailer 28 shown has two axles 32 with dual wheels 36 on each side of each axle, as is common on larger, heavy trailers. Each set of dual wheels 36 may also be referred to as a wheel end. The trailer 28 may be a single axle trailer and the axle may have a single pair of dual wheels, as will be apparent to those skilled in the art. Additionally, the techniques described herein are incorporated into other vehicles, eg, conventional two-axle vehicles. The trail...

Abstract

A flow indication system for a central tire inflation system is provided. The flow indication system provides a venturi in fluid communication with the conduit providing air to a tire. A pressure reading is taken at the inlet and throat of the venturi and the air flowing through the venturi is calculated based on the pressure differential. According to some embodiments, the pressure readings are provided to a microcontroller that uses a table and interpolation algorithms to calculate the flow of the air flowing through the venturi, such as the mass of air in a given unit of time (grams / second for example). In one embodiment, two separate pressure sensors are coupled to different ends of a narrowed orifice that causes a pressure change in the flow as flow rate increases in the throat of the sensor. This pressure change is then used to calculate a proportional flow that can then be broadcast to various parties instead of an on / off reading.

Description

[0001] Cross References to Related Applications [0002] The technology from which this application claims priority is U.S. Provisional Patent Application Serial No. 61 / 595,918, filed February 7, 2012, and entitled "Wireless Proportional Flow Indication for Tire Inflation Systems," the disclosure of which is hereby incorporated by reference in its entirety at this. technical field [0003] The present application relates to a central tire inflation system for maintaining tire pressure of a vehicle in operation. More specifically, the technology of the present application provides a wireless proportional flow indication of a central tire inflation system, allowing the operator to obtain real-time flow information. Background technique [0004] All vehicle operators are concerned with vehicle safety and efficiency. Safety is important to vehicle operators, passengers, and others in vehicles on the road. Safe vehicle operation also reduces vehicle maintenance costs and downt...
