Axial bearing for use in a hydraulic device, a hydraulic transformer and a vehicle with a hydraulic drive system

摘要

The invention concerns an axial bearing between a first part and a second part that presses with an axial load against the first part and can rotate around a rotation axis relative to the first part comprising a circular or arc-shaped ridge on the first part centered around the rotation axis, a pressure source for providing pressurized hydraulic fluid on a first side of the circular or arc-shaped ridge, an adjustable gap between the circular or arc shaped ridge and a bearing surface on the second part, wherein the pressurized hydraulic fluid flows through the adjustable gap to a second side of the circular or arc-shaped ridge. In accordance with the invention the circular or arc-shaped ridge and/or the bearing surface comprise(s) a ridge chamber for locally creating a larger adjustable gap between the circular or arc-shaped ridge and the bearing surface.
