Patent number: 10330160Abstract: A brake drum usable in a vehicle includes a substantially cylindrical wall having an end surface at one axial end thereof, with the substantially cylindrical wall defining a radially inwardly facing wear surface to be engaged by a friction lining upon brake actuation during operation of the vehicle. A radially extending drum section is joined by way of a corner section to another axial end of the substantially cylindrical wall and, together with the substantially cylindrical wall and the corner section, forms a drum interior volume. To provide for discharge of particles from the drum interior volume, the substantially cylindrical wall has a circumferentially extending cut away section in the wear surface located adjacent to the one axial wall end.Type: GrantFiled: November 2, 2017Date of Patent: June 25, 2019Assignee: Bendix Commercial Vehicle Systems, LLCInventor: David J.

Patent number: 7334847Abstract: An air supply system for a vehicle air braking system includes an air dryer and a reservoir assembly including a downstream section and a purge reservoir. The downstream section may be a supply or service reservoir or a multi circuit pressure protection valve. A passage extends through the purge reservoir between the air dryer and the downstream section. A delivery valve is in the passage. A purge passageway is on the reservoir assembly between the air dryer and the delivery valve and in fluid communication with the passage. In one embodiment, the reservoir assembly is remote from the air dryer, and only one air line connects the air dryer and the reservoir assembly.Type: GrantFiled: October 9, 2003Date of Patent: February 26, 2008Assignee: Bendix Commercial Vehicle Systems LLCInventor: David J.

Patent number: 6858066Abstract: An air dryer and reservoir assembly for providing compressed air from an air compressor (20) on a heavy motor vehicle which includes an air dryer (14) connected to receive compressed air from the air compressor (20) and a secondary reservoir (12), including an integral purge volume (34), for storing compressed air which passes through the air dryer (14), with the air dryer (14) and the secondary reservoir (12) being securely attached to a housing (16) to form an air dryer reservoir module (10). A primary, reservoir (18) for storing compressed air from the air dryer (14) is located remote from the air dryer reservoir module (10). A pressure equalizing mechanism (57) is disposed between the primary reservoir (18) and the secondary reservoir (12) for keeping pressure in the two reservoirs (12,18) equal.Type: GrantFiled: June 26, 2003Date of Patent: February 22, 2005Inventors: Leonard A.

Patent number: 6743277Abstract: A cargo or bulk product off-load system includes a compressor (10) that pressurizes air. The air is dried by a dryer (12, 14) and routed to a supply tank (16). From the supply tank, the air is either used to pressurize service reservoirs (24, 26) or to assist the off-load system. Air stored in the service reservoirs (24, 26) is used to pressurize purge volumes associated with the dryers (12, 14). The compressor (10) operates at a lower pressure when supplying air to assist the off-load system than when pressurizing the service reservoirs (24, 26). Controllers (30, 40) coordinate switching of airflow, and alternating purging and drying of the dryers.Type: GrantFiled: May 16, 2002Date of Patent: June 1, 2004Assignee: Bendix Commercial Vehicle Systems LLCInventors: David J.

Patent number: 6659244Abstract: A pneumatic actuator is integrated into a foot control valve. It includes a pneumatically activated piston that applies a force to the foot control valve primary piston which, in turn, applies the vehicle brake system. The piston is configured to allow the pedal or treadle actuated plunger to push through the pneumatic actuator and apply the brake system. This finds particular use as an add-on feature for pre-trip inspection systems, as a working brake system, etc.Type: GrantFiled: December 4, 2000Date of Patent: December 9, 2003Assignee: Bendix Commerical Vehicle Systems LLCInventor: David J.

Publication number: 20020147072Abstract: Operation of a vehicle, such as a tractor-trailer, is prevented or modified if operation of the vehicle would be dangerous or destructive due to a brake system abnormality. A motor controller limits the speed of a moving vehicle if a brake system reservoir pressure is below a predetermined threshold or if parking brakes are applied. Additionally, if there is a brake system abnormality, the motor controller limits the motor torque produced in a stationary or slowly moving vehicle. Electronically controlled brake system control modules are recruited to monitor brake system status information and report abnormalities to the motor controller. Preferably, the electronically controlled brake control modules communicate with the motor controller over a serial link.Type: ApplicationFiled: April 10, 2001Publication date: October 10, 2002Applicant: Bendix Commercial Vehicle Systems LLCInventors: David J. Goodell, David J. Knight

Patent number: 6318813Abstract: An emergency brake backup system is achieved by selectively interconnecting the air suspension as an additional reservoir to the air brake system. That is, if the charging system or primary reservoir fails, compressed air in the air spring reservoirs is used as an energy source to supply the pressurized air required for brake function. This can be achieved with minor modification to existing tractor and trailer brake systems that employ air suspension assemblies.Type: GrantFiled: January 20, 2000Date of Patent: November 20, 2001Assignee: Honeywell Commercial Vehicle Systems Co.Inventor: David J.

Patent number: 6220276Abstract: A control valve assembly for a heavy vehicle provides a symmetrical design that minimizes costs and provides a universal adaptation to a number of OEM configurations. The valve assembly can be used with different design platforms since symmetrical surfaces allow the valve body to be oriented as desired. Symmetrical mounting openings, alternate actuating lever mounting arrangements, and preselected angled orientation of the valve ports provide for the use of low-cost fittings that are useful in a wide variety of OEM configurations.Type: GrantFiled: January 20, 2000Date of Patent: April 24, 2001Assignee: Honeywell Commercial Vehicle Systems Co.Inventor: David J.

Patent number: 5286282Abstract: An air dryer for compressed air braking systems includes a desiccant canister which is provided with a double helix insert which cooperates with the walls of the canister to define a pair of intertwined, serpentine, pneumatically isolated flow paths. The flow paths extend through the canister between the end walls and are filled with a desiccant material. A single center line valve mechanism is provided to switch between the flow paths so that one of the flow paths is purged at the same time that the other flow path is pressurized.Type: GrantFiled: May 4, 1993Date of Patent: February 15, 1994Assignee: Allied-Signal Inc.Inventors: David J.
