Spring Brake Actuator with a Caging Bolt Bearing Joining a Pressure Plate and Actuator Tube

A pneumatic brake actuator, comprising:

• a housing comprising first and second end walls and a side wall joined with and extending between said end walls, wherein said first end wall presents an opening;
• a divider that divides said housing into a spring chamber positioned between said divider and said first end wall and a pressure chamber positioned between said divider and said second end wall, wherein said divider comprises a peripheral edge that engages said side wall of said housing and said divider presents an opening surrounded by an interior surface;
• a spring positioned in said spring chamber;
• an actuator tube comprising a side wall that encloses an interior space, wherein an end of said actuator tube is positioned within said opening in said divider;
• a bearing that is positioned within said opening in said divider, wherein said bearing is joined to said divider and to said actuator tube, and wherein said bearing presents an opening that is aligned with said opening in said first end wall;
• and
• a caging bolt comprising a first end positioned within said interior space of said actuator tube, wherein said caging bolt extends from said first end through each of said openings in said bearing and said first end wall to a second end positioned outside of said housing, and wherein said caging bolt is coupled with said first end wall.
