Publication number: 20230175482Abstract: An apparatus for a self-centering plunger for a hydraulic yaw brake having improved load distribution and ability to accommodate system forces, torques, stresses, etc. is disclosed. A lower section of the self-centering hydraulic plunger has a reduced diameter and does not include a bottom collar, which minimizes torque transfer from a brake piston. A brake piston seat washer is thicker, more robust and has increased surface area to better distribute the load onto the brake piston. The geometry of the piston seat washer also minimizes the torque transferred from the brake piston to the self-centering hydraulic plunger. A friction sleeve assembly improves load distribution at a plunger-housing interface by improving sliding contact surface area.Type: ApplicationFiled: November 30, 2022Publication date: June 8, 2023Applicant: Wind Solutions, LLCInventors: Bradley Keith Baldwin, Christopher James Winslow, Matthew Kenneth King
