Abstract
A brake actuator includes a flange case having a radially outwardly extending annular flange, a head having a radially outwardly extending annular flange, and a diaphragm having a widened outer periphery sandwiched between the annular flange of the flange case and the annular flange of the head. The diaphragm includes a reinforcing member embedded in or attached to an outer surface of the widened outer periphery thereof. The reinforcing member is formed of a material which is more resistant to deformation than a material of which the diaphragm is formed so as to inhibit the widened outer periphery of the diaphragm from pulling out from between the annular flange of the flange case and the annular flange of the head.
Claims25
A brake actuator comprising:
- a flange case having a radially outwardly extending annular flange;
- a head having a radially outwardly extending annular flange;
- and
- a diaphragm having a widened outer periphery, the widened outer periphery of said diaphragm being sandwiched between the annular flange of said flange case and the annular flange of said head, said diaphragm comprising a reinforcing member embedded in or attached to an outer surface of the widened outer periphery thereof, the reinforcing member being formed of a material which is more resistant to deformation than a material of which said diaphragm is formed so as to inhibit the widened outer periphery of said diaphragm from pulling out from between the annular flange of said flange case and the annular flange of said head.
A diaphragm adapted to be sandwiched between annular flanges on two housing components of a brake actuator, said diaphragm comprising:
- a widened outer periphery;
- a reinforcing member embedded in or attached to an outer surface of said widened outer periphery, the reinforcing member being formed of a material which is more resistant to deformation than a material of which said widened outer periphery is formed so as to inhibit said widened outer periphery from pulling out from between the annular flanges of the housing components.
