A ball ramp brake including a housing, a disc assembly within the housing, and an annular rotatable actuator to actuate the brake by compressing the disc assembly. The rotatable actuator includes a plurality of depressions oriented circumferentially therein which become progressively shallower in a first circumferential direction. A plurality of depressions are circumferentially oriented in a surface of the housing and become progressively shallower in a second circumferential direction. The depressions in the actuator and the depressions in the housing each have a first angle of depression that is steeper than a second angle of depression. A boot seal may be provided between the fluid chamber of an actuating cylinder and the inner area within the housing to prevent fluid leakage. In addition, a cooling chamber may be provided in the housing to improve the brakes efficiency.
A ball ramp brake comprising a housing, an actuator selectively rotatable about an axis to cause actuation of the brake, a plurality of depressions oriented circumferentially in said actuator and becoming progressively shallower in a first circumferential direction, a plurality of circumferentially oriented depressions in said housing adjacent to said actuator, said housing depressions becoming progressively shallower in a second circumferential direction, said depressions in said actuator and in said housing each having a first angle of depression and a second angle of depression, said first angle being greater than said second angle.
A ball ramp brake comprising a housing defining an inner chamber therein, a rotating actuator within said inner chamber of said housing, a cylinder adapted to be in fluid communication with a hydraulic actuating mechanism, said cylinder having a bore therein with an opening at one end of said bore, a piston slidably received within said bore to define a fluid chamber, a pushrod engaged by said piston and extending through said opening to engage said rotating actuator, and a seal positioned around said pushrod and over said opening, said seal isolating said fluid chamber from said inner chamber of said housing.
A ball ramp brake comprising a housing, a disc assembly chamber defined by said housing, a cooling fluid in said disc assembly chamber, a cooling chamber defined by said housing and in fluid communication with said disc assembly chamber;
A ball ramp brake comprising
