International Classification:

B60T 15/54
B60T 17/08
B60T 13/38
F16D 65/28

Abstract:

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.

Abstract:

A two stage brake actuation system including a push rod, a first actuator coupled to the push rod, and a second actuator. The first actuator may apply a first force to the push rod to move it between a brake clearance position and a brake adjacent position. The second actuator may apply a second force to the push rod to move it between the brake adjacent position and a brake applied position. The first actuator may be a large displacement, low force actuator, and the second actuator may be a small displacement, high force actuator. A method for braking a vehicle by applying a first force to a push rod to move it a first distance from a brake clearance to a brake adjacent position, and applying a second force to the push rod to move it a second distance from the brake adjacent to a brake applied position.

International Classification:

B60T 17/00
B01D 53/04
B01D 53/26

Abstract:

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.

International Classification:

B01D 53/26

US Classification:

95 41, 96118, 95 91

Abstract:

An air dryer with a rotor and desiccant positioned within an interior chamber of the rotor. The desiccant is positioned within the interior chamber of the rotor between the inlet and the outlet. The desiccant is configured to adsorb at least some of the water contained within air flowing from an inlet to an outlet of the rotor. As the rotor is rotated at a regeneration speed at least some of the water adsorbed by the desiccant moves to the outer surface of the desiccant and at least some of the water is separated from the outer surface of the desiccant. The rotor directs water separated from the outer surface of the desiccant to at least one opening in the rotor. A method for drying air by sending the air through desiccant and rotating the desiccant at a regeneration speed to separate water from the desiccant.

International Classification:

B01D 46/00

US Classification:

96400

Abstract:

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.
