Abstract
A locking actuator arrangement may comprise an actuator housing defining a retaining cavity, an actuator piston comprising a piston head and a piston rod extending from the piston head, a receptacle body defining a receiving cavity, wherein the receiving cavity is configured to receive at least a portion of the piston rod, and the piston rod is configured to be received by the receiving cavity in response to alignment of at least two coupled links.
Claims18
A locking actuator arrangement for a landing gear comprising:
- a housing link extending from a pivot in a first direction and extending along a first longitudinal axis;
- an actuator housing extending from the pivot in a second direction, the second direction is opposite the first direction, the actuator housing defining a retaining cavity;
- a receiving link pivotally coupled to the housing link and defining a receiving cavity, the receiving link comprises a second longitudinal axis;
- and
- an actuator piston comprising a piston head and a piston rod extending from the piston head;
- wherein the receiving cavity is configured to receive at least a portion of the piston rod, and
- the piston rod is configured to be received by the receiving cavity in response to a pre-determined alignment of the housing link and the receiving link.
A landing gear arrangement, comprising:
- a housing link comprising a first longitudinal axis;
- a receiving link pivotally coupled to the housing link, the receiving link comprises a second longitudinal axis;
- an actuator housing coupled to the housing link and defining a retaining cavity;
- and
- an actuator piston comprising a piston head and a piston rod extending from the piston head, the actuator piston moves along a third longitudinal axis, wherein the third longitudinal axis is offset from the first longitudinal axis,
- wherein the receiving link defines a receiving cavity, and
- the piston rod is configured to be received by the receiving cavity in response to the landing gear arrangement being deployed.
A method for a locking actuator arrangement for a landing gear comprising:
- biasing an actuator piston to extend from an actuator housing coupled to a housing link;
- receiving, by a receiving cavity, the actuator piston;
- engaging, by the actuator piston, the receiving cavity;
- and
- preventing, by the actuator piston, the housing link from rotating relative to a receiving link, in response to the engaging,
- wherein the housing link extends from a pivot in a first direction and extends along a first longitudinal axis;
- the actuator housing extends from the pivot in a second direction, the second direction is opposite the first direction, the actuator housing defines a retaining cavity;
- the receiving link is pivotally coupled to the housing link, the receiving link defines the receiving cavity, the receiving link comprises a second longitudinal axis;
- the actuator piston comprises a piston head and a piston rod extending from the piston head;
- the receiving cavity is configured to receive at least a portion of the piston rod, and
- the piston rod is configured to be received by the receiving cavity.
