Filed:

May 8, 2001

Appl. No.:

09/852232

Inventors:

John J. Kemer - Avon Lake OH
Andrew Marsh - Elyria OH

Assignee:

Bendix Commercial Vehicle Systems, LLC

International Classification:

B60T 1300

US Classification:

303 7, 91426, 137596

Abstract:

A braking system control requires that a first or service braking system be actuated before a second or parking braking system can be released to prevent unexpected movements. A sensor senses that the service brakes are engaged and controls a device to release the parking brakes. A latch ensures that the parking brakes remain released. For example, a piston and check valve form the sensor and latch. Service brake pressure works against the piston. Above a threshold level, service brake pressure drives the piston to open a valve that provides pressurized air to a parking brake release system. Once released, the check valve directs parking brake release pressure to the piston to keep the valve open.

International Classification:

B60T 1300

US Classification:

303 40, 303 63, 137102

Abstract:

A combined spring brake modulating relay valve integrates the functions of a relay valve and a modulating valve. The housing includes a valve assembly movable in response to air pressure provided to selected ports in the housing. A relay piston selectively communicates with a control port and a primary brake circuit port. A modulating piston includes surfaces selectively pressurized by the primary brake circuit port and a secondary brake circuit port. This modulates the pressure from the delivery port to thereby selectively apply the associated spring brakes if a failure is detected at the primary brake circuit port. The exhaust member selectively controls communication between the supply and delivery ports as necessary.

Assignee:

Bendix Commercial Vehicle Systems, LLC - Elyria OH

International Classification:

G05G 1/10

US Classification:

74553

Abstract:

A cover for a vehicle parking brake control valve button including an elastomeric body and a plurality of elastic ridges. The body of the cover includes a rim and a recess designed to fit the contour of the control valve button. The ridges are designed to provide enough rigidity to support pressure applied thereto, and enough elasticity to absorb energy created by the actuation of the button. The absorption of the energy dampens the stinging sensation typically felt by the operator when actuating the parking brakes.

US Classification:

137 1521, 13731509, 251298, 3031181, 303 56

Abstract:

A configurable control valve for use with air brake systems is provided. This control valve includes: a first or top body portion, a second or bottom body portion, and a connector for attaching the first body portion to the second body portion. The first body portion may include an actuator or handle having either a linear translation a rotational translation, and the second body portion may include either horizontal or vertical port configurations. The connector cooperates with the first body portion and the second body portion to provide complete 360 lateral rotation of the body portions relative to one another.

US Classification:

137102, 137851, 303 64, 303 33, 303 40

Abstract:

A valve for use in a pneumatic system of a truck-trailer having a source of air under pressure, a reservoir, at least one spring brake unit and a brake service line is provided. The valve includes a housing, a pressure protection valve portion, a spring brake actuation valve portion and an anti-compounding valve portion. The housing has a supply passage in communication with the source of air under pressure. The pressure protection valve portion is disposed within a first chamber of the housing. The first chamber has an inlet in communication with the supply passage and an outlet in communication with the reservoir. The pressure protection valve portion is configured to selectively block the flow of pressurized air from the supply passage to the reservoir through the first chamber. The spring brake actuation valve portion is disposed within a second chamber of the housing.
