Abstract
An airbrake reservoir lock system for an airbrake system of a vehicle is provided. The vehicle has an electronic control module. The airbrake reservoir lock system comprises a primary air reservoir, and a first airbrake reservoir lock. The primary air reservoir has an input port and an output port. The primary air reservoir stores an amount of pressurized air. The first airbrake reservoir lock is disposed in fluid communication with the output port of the primary air reservoir. The first airbrake reservoir lock has a valve portion and an electrical actuator. The valve portion has an open position and a closed position. The electrical actuator positions the valve portion of the first airbrake reservoir lock between the open position and the closed position based upon an output of the electronic control module.
Claims19
An airbrake reservoir lock system for an airbrake system of a vehicle, the vehicle having an electronic control module, the airbrake reservoir lock system comprising:
- a primary air reservoir having an input port and an output port, the primary air reservoir provided for storing pressurized air;
- a first airbrake reservoir lock disposed in fluid communication with the output port of the primary air reservoir, the first airbrake reservoir lock having a valve portion and an electrical actuator, the electrical actuator being disposed in electrical communication with the electronic control module, the valve portion having an open position and a closed position,
- wherein the electrical actuator moves the valve portion of the first airbrake reservoir lock between the open position and a closed position in response to an output signal from the electronic control module;
- and
- a second airbrake reservoir lock disposed in fluid communication with the input port of the primary air reservoir, the second airbrake reservoir lock having a second valve portion and a second electrical actuator, the second electrical actuator being disposed in electrical communication with the electronic control module, the second valve portion having an open position and a closed position,
- wherein the second electrical actuator moves the second valve portion of the second airbrake reservoir lock between the open position and a closed position in response to an output signal from the electronic control module.
A method of limiting air flow from an airbrake reservoir of a vehicle having an airbrake system, and an electronic control module, the airbrake system having at least an airbrake reservoir and at least one airbrake reservoir lock in fluid communication, the method comprising:
- providing an airbrake reservoir lock in fluid communication with an airbrake reservoir;
- receiving a first output signal from the electronic control module actuating the airbrake reservoir lock to a locked position in response to the first output signal;
- and
- receiving a second output signal from the electronic control module actuating the airbrake reservoir lock to an unlocked position in response to the second output signal, wherein the airbrake reservoir lock restricts air flow through the airbrake reservoir lock when the airbrake reservoir lock is in the locked position, and wherein the airbrake reservoir lock allows air flow through the airbrake reservoir lock when the airbrake reservoir lock is in the unlocked position.
An airbrake reservoir lock system for an airbrake system of a vehicle, the vehicle having an electronic control module, the airbrake reservoir lock system comprising:
- an air reservoir having a primary portion, a secondary portion, and an input port, the primary portion having a primary portion output port, and the secondary portion having a secondary portion output port, the air reservoir provided for storing pressurized air;
- a first airbrake reservoir lock disposed in fluid communication with the output port of the primary portion of the air reservoir, the first airbrake reservoir lock having a valve portion and an electrical actuator, the electrical actuator being disposed in electrical communication with the electronic control module, the valve portion having an open position and a closed position;
- and
- a second airbrake reservoir lock disposed in fluid communication with the output port of the secondary portion of the air reservoir, the second airbrake reservoir lock having a second valve portion and a second electrical actuator, the second electrical actuator being disposed in electrical communication with the electronic control module, the second valve portion having an open position and a closed position,
- wherein the electrical actuator moves the valve portion of the first airbrake reservoir lock between the open position and a closed position in response to an output signal from the electronic control module, and
- wherein the second electrical actuator moves the second valve portion of the second airbrake reservoir lock between the open position and a closed position in response to an output signal from the electronic control module.
