Air-operated brake actuator mounting

In a set of at least two brake actuators of different sizes in combination with a bracket for mounting each of said brake actuators, each said brake actuator being of the type having a housing with a central opening therein, a push rod extending through the opening and reciprocally operable to actuate a brake in response to the movement of fluid into the housing, and at least two mounting studs extending from the housing for mounting the brake actuator to said bracket, said bracket having corresponding apertures to receive the mounting studs, the improvement in the set comprising:

• the mounting studs of a second of said brake actuators are secured to an exterior surface of the housing;
• and
• the mounting studs on each of said housings being spaced from each other substantially the same distance from each other and having substantially the same spacial arrangement with respect to each other and the bracket apertures corresponding to the spacial arrangement and spacing of the mounting studs on each of said housings, whereby differently sized brake actuators can be interchangeably mounted to the same bracket via the corresponding apertures.

• the mounting studs of one of said brake actuators are secured to an exterior surface of its respective housing;
• and
• the mounting studs on each of said housings being spaced from each other substantially the same distance from each other and having substantially the same spacial arrangement with respect to each other and the bracket apertures corresponding to the spacial arrangement and spacing of the mounting studs on each of said housings, whereby differently sized brake actuators can be interchangeably mounted to the same bracket via the corresponding apertures.

In a set of at least two brake actuators of different sizes and being adapted to mount to a bracket having apertures, each said brake actuator being of the type having a housing with a central opening therein, a diaphragm spanning the housing and dividing the housing into a first chamber adapted to receive and exhaust pressurized air and a second chamber, a push rod extending through the opening and operably connected to the diaphragm to reciprocally actuate a brake in response to the receipt and exhaustion of fluid into the first chamber, and at least two mounting studs extending from the housing for mounting the brake actuator to said bracket, and at least one of the brake actuators having a diaphragm with a nominal effective area less than twenty in.sup.2, the improvement in the set comprising:

• the mounting studs on each of said housings being spaced from each other substantially the same distance from each other and having substantially the same spacial arrangement with respect to each other and with respect to the bracket apertures, whereby differently sized brake actuators can be interchangeably mounted to the same bracket via the corresponding apertures.
