First Claim
Patent Images
1. An integrated wireless data system for measuring operational characteristics of a wheel hub assembly in a vehicle, comprising:
- a remote unit having at least one sensor and a remote transceiver and an A/D converter and a microprocessor for measuring operational data of the wheel hub assembly;
said remote unit including a power source connected to and providing power to said remote unit;
a base unit having a base transceiver and a microprocessor connected to and in communication with a data acquisition system;
said remote unit and base unit wirelessly communicating with one another to exchange the operational data in real-time and bi-directionally;
said remote unit including a housing and a hub insert coupled to said housing and extending along an axis and radially to an outer periphery and configured to engage a tapered portion and a pocket of a wheel hub and defining a central through hole disposed centrally about the axis and extending axially through said hub insert and said hub insert defining at least one radial opening extending radially from the central through hole to the outer periphery;
said hub insert includes a threaded draw bar disposed in said central through hole; and
said hub insert includes at least one sliding pin disposed in said at least one radial opening and having a first end adjacent said threaded draw bar and a second end adjacent the tapered portion of the wheel hub and configured to be forced radially outwardly into engagement with the tapered portion in response to engagement by said threaded draw bar as said threaded draw bar pulls said hub insert into the pocket.

11. A method for measuring operational characteristics of a wheel hub assembly under real-world operating conditions, comprising the steps of:
-
installing a remote unit on a wheel hub assembly; pulling a hub insert of the remote unit into a pocket of the wheel hub assembly using a threaded draw bar; forcing at least one sliding pin of the hub insert radially outwardly into engagement with a tapered portion of the wheel hub assembly in response to engagement by the threaded draw bar as the threaded bar pulls the hub insert into the pocket; measuring the operational characteristics of the wheel hub assembly using the remote unit; and wirelessly transmitting the operational characteristics of the wheel hub assembly to a base unit. - View Dependent Claims (12, 13, 14)

15. A method to configure an integrated wireless data system including a base unit in wireless communication with a remote unit and said base unit connected to data acquisition system to collect operational characteristics of the wheel hub assembly, comprising the steps of:
-
installing the remote unit to the wheel hub assembly; pulling a hub insert of the remote unit into a pocket of the wheel hub assembly using a threaded draw bar; forcing at least one sliding pin of the hub insert radially outwardly into engagement with a tapered portion of the wheel hub assembly in response to engagement by the threaded draw bar as the threaded bar pulls the hub insert into the pocket; collecting data associated with the operational characteristics using the remote unit and the base unit of the integrated wireless data system;
connecting the base unit to a data acquisition system; andconfiguring the data acquisition system to store the collected data for processing.
