摘要:
A system for a vehicle includes a hollow axle, a wheel hub which surrounds the axle, bearings provided therebetween, at least one nut having a predetermined inner diameter mounted on an end of the axle, and a hub cap mounted to the wheel hub. An exciting element is mounted within the hub cap by a mounting wheel. A sensor member is mounted in the end of the axle and radially spaced from the exciting element. The sensor member has an outer diameter which is less than the inner diameter of the nut such that the wheel hub, the bearings, the nut, the hub cap, the exciting element and the mounting wheel can be removed without having to remove the sensor member from the axle.

A novel diagnostic system for a trailer is provided by the present invention. The trailer includes a micro controller which is part of an anti-lock brake system of the trailer. A warning light is provided on the trailer and is in electrical connection with the micro controller. A switch is provided proximate to the warning lamp. The switch can be activated by a technician to provide a short across the warning lamp. A stored program within the micro controller recognizes the short and performs a diagnostic function in response thereto by flashing the warning lamp in a predetermined manner.

The present invention relates to a vehicle brake system, which has a brake reservoir, and utilizes a tire management system that is in communication with the brake reservoir and a vehicle operator. As a result of this configuration, the tire management system communicates brake reservoir pressure signals to the vehicle operator, so that the operator is made aware of any low pressure conditions, in the trailer, before trying to move the trailer.

A control system for a machine having a transmission system is provided. The control system includes a wheel speed sensor and a controller. The wheel speed sensor is configured to generate a signal indicative of a wheel speed. The controller is in communication with the wheel speed sensor. The controller is configured to modulate a parameter of a power source based, at least in part, on a comparison of the wheel speed and a localized speed of the machine near the wheel.
摘要:
A control system includes a microcontroller which receives input signals from input sensors and transmits output signals to electrically actuated solenoid valves in response to the input signals. A drive circuit controller is responsive to the output signals and to a solenoid enable signal generated by a watchdog circuit to control the solenoid valves. The watchdog circuit is responsive to watchdog pulses generated by the microcontroller and transmitted through the watchdog port of the microcontroller to generate the solenoid enable signal. The watchdog circuit generates the solenoid enable signal only when the frequency of the pulses generated at the watchdog port is within a relatively narrow frequency range. Accordingly, the watchdog circuit disables the drive circuits during failure of the microcontroller to assure that the solenoids will not be operated.

The present invention relates to a vehicle wheel sensor apparatus and a method that determine if a vehicle wheel sensor is active or passive, while efficiently providing the necessary connectivity, power, and communication between the sensor and a controller, without requiring a change in controller hardware. For an active sensor, the apparatus provides power and receives speed signals, high frequency vibration or acceleration signals, or other analog signals. For a passive sensor, the apparatus receives speed signals.
摘要:
A tire inflation system and wheel speed sensor system having a hollow shaft rotatable with a drive mechanism. The shaft extends into the hollow end of an axle. A angular velocity system rotates with the shaft within the hollow end of the axle. A sensor, mounted within the axle, senses the rotation of the angular velocity system. The hollow shaft is a conduit for air from an air source to at least one tire.
