Abstract
A brake adjustment indicator for an air brake having a brake chamber, comprises a body including a cavity within, the body including a passageway having an inlet and an outlet communicating with the cavity, the inlet and outlet being adapted for connecting to an air line connected to the brake chamber such that pressurized air is routed through the cavity to turn the impeller whenever the air brake is activated; an impeller rotatably supported within the cavity; a sensor disposed adjacent the impeller for sensing the rotation of the impeller; and a display counter for counting and displaying the amount of rotation of the impeller which is indicative of the amount of air required to activate the air brake.
Claims19
A brake adjustment indicator for an air brake having a brake chamber, comprising:
- a) a body including a cavity within;
- b) an impeller rotatably supported within said cavity;
- c) said body including a passageway including an inlet and an outlet communicating with said cavity, said inlet and outlet being adapted for connecting to an air line connected to the brake chamber such that pressurized air is routed through said cavity to turn said impeller whenever the air brake is activated;
- d) a sensor disposed adjacent said impeller for sensing the rotation of said impeller;
- and
- e) a display counter for counting and displaying the amount of rotation of said impeller which is indicative of the amount of air required to activate the air brake.
A brake adjustment indicator for an air brake having a brake chamber, comprising:
- a) a body having a cavity within;
- b) an impeller rotatably supported within said cavity;
- c) said body including a passageway including an inlet and an outlet communicating with said cavity, said inlet and outlet being adapted for connecting to an air line connected to the brake chamber such that pressurized air is routed through said cavity to turn said impeller whenever the air brake is activated;
- d) said passageway including a bypass portion;
- e) a sensor secured to said body and adjacent said impeller for sensing the rotation of said impeller;
- and
- f) a display counter for displaying data indicative of the amount of rotation of said impeller, thereby to indicate the amount of air required to activate the air brake and the extent of adjustment of the brakes.
An air brake, comprising:
- a brake chamber connected to a source of pressurized air;
- b) a housing and an impeller disposed within said housing;
- c) said housing is connected between said brake chamber and the source of pressurized air such that pressurized air is routed through said housing to turn said impeller whenever said air brake is activated;
- d) a sensor for sensing the rotation of said impeller required to engage the air brake;
- and
- e) a display counter for counting and displaying the amount of rotation of said impeller thereby to provide an indication of the amount of air required to activate the air brake.
A process for determining the extent of adjustment of an air brake, comprising:
- a) activating the air brake;
- b) providing an indication of the amount of air required to activate the air brake by measuring the amount of rotation of a wheel caused to turn whenever the air brake is activated;
- and
- c) comparing the amount to a standard level.
