Patent number: 8869831Abstract: A traction valve is provided for use in combination with a relay valve. The traction valve includes a body configured for connection to a housing of the relay valve and defining inlet, outlet and traction supply ports. A first fluid control valve used for traction control is supported on the body and includes a valve member that alternately permits and prevents fluid communication between the traction supply and outlet ports in the body. The body and the first fluid control valve are configured to receive any of a plurality of interchangeable second fluid control valves between the inlet port in the body and the first fluid control valve. Each of the plurality of interchangeable second fluid control valves is configured to perform a different function such that the traction valve assumes different configurations upon assembly of the various second fluid control valves with the body and the first fluid control valve.Type: GrantFiled: May 25, 2011Date of Patent: October 28, 2014Assignee: Bendix Commercial Vehicle Systems LLCInventors: Craig S.

Patent number: 8818673Abstract: When detecting unacceptably large airgaps between wheel speed sensors and their exciter rings on wheel ends of a vehicle, wheel speed sensor output is filtered and monitored to detect signal amplitudes that correspond to the airgaps. When signal peak amplitude below a predetermined threshold is detected, the airgap is too large. Wheel ends having unacceptably large air gaps are indicated to the driver or technician via blink sequences (e.g., on an electronic stability program (ESP) indicator light or other suitable indicator), wherein each wheel end is associated with a unique blink sequence.Type: GrantFiled: March 28, 2013Date of Patent: August 26, 2014Assignee: Bendix Commercial Vehicle Systems LLCInventors: Timothy J. Frashure, Thomas J. Weed, Craig S. Haehn, Kirit A. Thakkar, Julie A. Miller, Daniel P. Zula

Patent number: 6114952Abstract: A remote fault indicating unit (12) for an electronic system, such as a vehicle adaptive braking system, includes a series of visual indicators, such as light emitting diodes (50-59), on one surface of the housing and a computer serial port connector (13) for use when troubleshooting is done with a PC (18) equipped with the appropriate software. Each of the indicators (50-59) is activated in response to a predetermined malfunction sensed in the system, such as a defective speed sensor, defective modulator, or a defect in the electronic circuitry. The indicators (50-59) are reset with a switch (15) when the system is repaired. When the reset switch (15) is activated, all of the indicators (50-59) flash on and are then turned off. The reset switch (15) can also be activated for a longer period of time changing the ECU (14) configuration.Type: GrantFiled: February 27, 1998Date of Patent: September 5, 2000Assignee: AlliedSignal Truck Brake Systems Co.Inventors: James E.
