摘要： A hydraulically operated pivotal joint for dampening a swing motion of a swing damping device, the hydraulically operated pivotal joint comprising a non-pivoting pin, a first inner channel arrangement comprising a first pressure inlet for providing an inlet for a pressure medium, a first braking arrangement arranged to create a braking force for dampening the swing motion, wherein the braking force is provided by the first braking arrangement by means of pressure provided by the pressure medium conducted to the first braking arrangement via the first inner channel arrangement. The first inner channel arrangement comprises a first pressure outlet, where to the pressure medium is conducted from the first pressure inlet through the non-pivoting pin and through the first braking arrangement to enable conducting of the pressure medium for a second hydraulically operated moving apparatus of the swing damping device.

摘要： A radial piston hydraulic motor (4) comprises a cam ring provided with a wave-shaped inner surface and radial cylinders provided in the inner part inside the cam ring and pistons that move therein as well as rollers coupled to the pistons so as to follow the inner surface of the cam ring. By the effect of the working pressure of hydraulic oil conveyed to the cylinders, the rollers that are pressed against the inner surface of the cam ring provide a rotating movement of the cam ring and the inner part relative to each other. The hydraulic motor (4) is provided with means disengaging the rollers coupled to the pistons from contact to the inner surface of the cam ring when the working pressure stops acting in the cylinders for bringing the hydraulic motor (4) into freewheeling. The hydraulic motor (4) is provided with a control coupling which, when the prevailing pressure of hydraulic oil in the working pressure line (5) that leads to the cylinders drops below a specific level, automatically disengages the cylinders from the working pressure line (5) and couples the hydraulic motor (4) into freewheeling.

摘要翻译：径向活塞液压马达（4）包括凸轮环，凸轮环设置有波形内表面和设置在凸轮环内部的内部的径向气缸以及在其中移动的活塞以及联接到活塞的滚子，以便跟随凸轮环的内表面。通过输送到气缸的液压油的工作压力，压靠在凸轮环的内表面上的辊提供凸轮环和内部相对于彼此的旋转运动。当液压马达（4）在工作压力停止作用在气缸中以使液压马达（4）进行自由运转时，设有使与活塞相连接的滚子与接触件脱离接触到凸轮环的内表面的装置。液压马达（4）设有控制联轴器，当工作压力线（5）中通向气缸的液压油的主要压力下降到特定水平以下时，液压马达（4）自动脱离工作压力线（ 5）并将液压马达（4）耦合到续流中。
