Wheel end sensor for heavy-duty vehicles
First Claim
1. A sensor for a wheel end assembly of a heavy-duty vehicle, said wheel end assembly including a wheel hub and a hub cap removably mounted on said wheel hub, said sensor comprising:
- mounting means disposed in said hub cap, said hub cap being mounted on an outboard end of said wheel hub to prevent leakage of lubricant from the wheel hub and to prevent contaminants from entering said wheel hub;
sensing means mounted on said mounting means to sense at least one operational condition of said vehicle;
a processor mounted on said mounting means and electrically connected to said sensing means to process data from said sensing means;
communication means mounted on said mounting means and electrically connected to said processor to communicate said processed data to a user; and
an electrical energy storage device mounted on said mounting means and electrically connected to said sensing means, said processor and said communication means to power said sensor.

Abstract
A wireless sensor for a wheel end assembly of a heavy-duty vehicle is provided. The wheel end assembly includes a wheel hub and a hub cap mounted on the wheel hub. The sensor includes mounting means disposed in the hub cap. Sensing means are mounted on the mounting means to sense at least one condition of the vehicle. A processor is mounted on the mounting means and is electrically connected to the sensing means to process data from the sensing means. Communication means are mounted on the mounting means and are electrically connected to the processor to communicate the processed data to a user. An electrical energy storage device is mounted on the mounting means and is electrically connected to the sensing means, the processor and the communication means, enabling the sensor to be independent from the vehicle power supply. The sensor also accommodates components of a tire inflation system.
