Abstract
A torque link assembly may comprise an upper torque link, a lower torque link, and a torque link pin. The upper torque link may define an upper hydraulic fluid channel. The lower torque link may define a lower hydraulic fluid channel. The torque link pin may fluidly couple the upper hydraulic fluid channel to the lower hydraulic fluid channel.
Claims18
A torque link assembly, comprising:
- an upper torque link defining a first upper hydraulic fluid channel;
- a lower torque link defining a first lower hydraulic fluid channel;
- and
- a torque link pin fluidly coupling the first upper hydraulic fluid channel to the first lower hydraulic fluid channel, wherein the torque link pin includes a pin inlet, a pin outlet, and a first internal pin channel, and wherein the first internal pin channel provides a fluid connection between the pin inlet and the pin outlet, the pin inlet being located at the upper torque link, and the pin outlet being located at the lower torque link;
- and
- wherein an outer circumferential surface of the torque link pin defines an upper link groove, the upper link groove being located at an outlet of the first upper hydraulic fluid channel, and wherein the upper link groove is configured to allow hydraulic fluid to flow from the first upper hydraulic fluid channel into the first internal pin channel when the outlet of the first upper hydraulic fluid channel is circumferentially offset from the pin inlet.
3 more elements
A shock strut assembly, comprising:
- a strut cylinder;
- a strut piston configured to telescope relative to the strut cylinder;
- an upper torque link coupled to the strut cylinder, wherein the upper torque link defines a first upper hydraulic fluid channel;
- a lower torque link configured to pivot relative to the upper torque link, the lower torque link defining a first lower hydraulic fluid channel;
- and
- a torque link pin fluidly coupling the first upper hydraulic fluid channel to the first lower hydraulic fluid channel, wherein the torque link pin includes a pin inlet, a pin outlet, and a first internal pin channel, and wherein the first internal pin channel provides a fluid connection between the pin inlet and the pin outlet, the pin inlet being located at the upper torque link, and the pin outlet being located at the lower torque link;
- and
- wherein an outer circumferential surface of the torque link pin defines an upper link groove, the upper link groove being located at an outlet of the first upper hydraulic fluid channel, and wherein the upper link groove is configured to allow hydraulic fluid to flow from the first upper hydraulic fluid channel into the first internal pin channel when the outlet of the first upper hydraulic fluid channel is circumferentially offset from the pin inlet.

A landing gear assembly, comprising:
- an upper torque link defining a first upper hydraulic fluid channel;
- a lower torque link defining a first lower hydraulic fluid channel;
- a torque link pin fluidly coupling the first lower hydraulic fluid channel and the first upper hydraulic fluid channel;
- and
- a hydraulic piston in fluid communication with the first lower hydraulic fluid channel,
- wherein the torque link pin includes a pin inlet, a pin outlet, and a first internal pin channel, and wherein the first internal pin channel provides a fluid connection between the pin inlet and the pin outlet, the pin inlet being located at the upper torque link, and the pin outlet being located at the lower torque link;
- and
- wherein an outer circumferential surface of the torque link pin defines an upper link groove, the upper link groove being located at an outlet of the first upper hydraulic fluid channel, and wherein the upper link groove is configured to allow hydraulic fluid to flow from the first upper hydraulic fluid channel into the first internal pin channel when the outlet of the first upper hydraulic fluid channel is circumferentially offset from the pin inlet.
