| 摘要 |
The present invention relates to a hydraulic axial-piston machine comprising a driving shaft (1) and a number of axially directed pistons (16, 64) arranged for to-and-fro movement each in its own cylinder (15, 65), provided with inlets and outlets for liquid, wherein an inclined disc (13, 32) is arranged to transmit movement between the pistons and the driving shaft. In accordance with the invention the disc (13, 32) is provided with a shaft end (9, 50) forming an angle with the driving shaft (1) and being connected to the driving shaft by means of a bearing (7, 8, 10, 11). The bearing permits relative rotation between the driving shaft (1) and the shaft end (9, 50), which achieves a tilting movement in the disc (13, 52). Each piston (16, 64) co-operates with the disc (13, 52) via a ball joint member comprising a first part (17, 61) that has a convex spherical surface and a second part (18, 62) that has a concave spherical surface, which first part is pivotably journalled in the second part. |
