摘要： A method for monitoring a wheel system by comparing a wheel end temperature to a wheel end temperature threshold; generating a brake monitoring signal when at least one brake monitoring condition has occurred; and generating a wheel monitoring signal if a brake monitoring signal is generated when the wheel end temperature is greater than the wheel end temperature threshold. The brake monitoring conditions may include (i) a brake supply pressure is less than a brake supply pressure threshold; (ii) a brake control pressure is greater than a first brake control pressure threshold and a stop lamp power signal is not present; and/or (iii) the stop lamp power signal is present and the brake control pressure is not greater than a second brake control pressure threshold. A brake monitoring system configured to monitor a wheel system.

摘要： A brake adjuster with a housing configured to be coupled to a brake actuator push rod, and a control unit rotatably coupled to the housing. The control unit is configured to be coupled to a reference point of a vehicle and to cause adjustment of the brake as the brake actuator push rod retracts. One of the housing and the control unit has a first indicator and a second indicator, and the other of the housing and the control unit has a third indicator. The third indicator is adjacent the first indicator when the brake actuator push rod is retracted in a brake disengaged position, and the third indicator is adjacent the second indicator when the brake actuator push rod is extended to a brake over-stroke position. The indicators may be any combination of notches, protrusions, marks, or pointers.

摘要： A brake actuator with a pushrod configured to actuate a brake of a vehicle. The pushrod is movable between a retracted position and an extended position to actuate the brake. A brake actuator component is operatively coupled to the pushrod. A sensor is configured to emit a signal directed toward the brake actuator component and to receive the signal after the signal bounces off the brake actuator component and is reflected back to the sensor. A disc brake with a disc brake component and a sensor configured to emit a signal directed toward the disc brake component. The sensor is configured to receive the signal after the signal bounces off the disc brake component and is reflected back to the sensor. The sensor may be an acoustic sensor.

摘要： An air dryer assembly with manifold system provides increased drying capacity for pressurized air systems, such as vehicle braking systems. A manifold connected to the supply ports of two adjacent air dryers allows parallel flow of air through the separate air dryers. An identical manifold connects to the delivery ports of the two air dryers to combine the clean, dry air from the delivery ports. Similar manifolds connect the control and purge ports of the dryers to allow simultaneous regeneration of the desiccant canisters. An assembly combining two air dryers, two pretreatment units, and manifolds connecting the supply, delivery, control, and purge ports of two air dryers is also disclosed.

摘要： A pneumatic brake actuator has a spring brake actuator with spring and spring brake pressure chambers, and a service brake actuator with service brake pressure and pushrod chambers. A control valve has a seal that is moveable between an open position and a closed position for regulating fluid flow between the spring chamber and service brake pressure chamber. A first surface of the seal is in fluid communication with the service brake pressure chamber and a second surface of the seal is in fluid communication with a valve chamber that is not in fluid communication with the service brake pressure chamber or spring chamber. The seal moves between its open and closed positions based on a pressure in the service brake pressure chamber. Movement of the seal is not dependent on the rate of flow of fluid between the spring chamber and the service brake pressure chamber.

摘要： An air dryer cartridge having an outer shell, an inner shell positioned within the outer shell, and a check valve positioned at least partially between the inner and outer shells. The inner and outer shells each have an inlet and an outlet. The outer shell is preferably operable to removably engage an air dryer. The check valve is operable to regulate the rate of flow of fluid through the outlet of the inner shell. Preferably, the check valve also seals between portions of the inner and outer shells and/or is operable to sealingly engage an air dryer.

摘要： A brake actuator assembly including a pressure plate presenting an opening, a push rod that is coupled to the pressure plate, a diaphragm that is coupled to the pressure plate, and a retainer that engages the push rod. The push rod has an outer surface and at least one protrusion extending outward from the outer surface. The retainer engages the protrusion such that at least a portion of the diaphragm is positioned between the pressure plate and the retainer.

摘要： A valve having an inlet, exhaust, control port, and diaphragm. The diaphragm moves between an open position, in which the inlet and exhaust are in fluid communication, and a closed position, in which the diaphragm blocks fluid from flowing between the inlet and the exhaust. The diaphragm moves from the closed position to the open position when an inlet force due to pressure at the inlet is greater than the sum of the biasing force and a control port force due to pressure at the control port. The valve is operable to automatically drain contaminants from a vehicle air reservoir when the vehicle's emergency brakes are set. To reduce noise, the diaphragm of the valve is preferably in tension when in the closed position, and/or the diaphragm opens a limited distance when in the open position so that a back pressure is generated at the inlet.
