Abstract:
The aim of the invention is to create a friction disc in a brake or clutch, wherein a friction lining (2) would have to be reliably attached to a base part (1) and wherein each effective surface of said friction lining (2) could be maintained in better condition just in order to ensure each required friction coefficient and consequently each desired torque transmission. Such friction disc comprises a base part (1), which is arranged axially symmetrically with respect to a central axis (100) and rotatably around it, and moreover comprises a circular front surface (11) and a centrally arranged driving collar (12). Said disc is furthermore furnished with an annular friction lining (2), which is attached in a radially outward area of said front surface (11) of the base part (1) and is secured against rotation relatively to said base part (1) by means of at least two mechanical securing members (3), at least one of which is adapted to be rest on the one hand on the material of said base part (1) and on the other hand on the material of said friction lining (12). In addition to that, said friction disc is also furnished with a plurality of cleaning grooves (4), which are in the circumferential direction of the disc equidistantly spaced apart from each other and extend each per se in a direction from the central axis of said driving collar (12) towards the circumference of the disc. Each of said securing members (3) is essentially cylindrical, but the cross-section thereof in the plane of said front surface (11) of the base part (1) is shaped in the form of letter D and furnished with a planar cutoff (31). The shape of the friction lining (2) and the base part (1) is adjusted to such shape of each securing member (3).

The invention refers to a link member (1) on an arm (90) of a crane (9), which pivotally connected around the horizontal axis (x) to said arm (90) by means of a pivot joint (95), and pivotally connected to a grabber (8) around a further horizontal axis (y), which is perpendicular to the previously mentioned horizontal axis (x), wherein said grabber (8) is furnished with a rotator (81) for rotation of the grabber (8) around the vertical axis (z). To determine the weight of a load held by said grabber (8) the link member (1) comprises an elastically deformable area (13) between said pivot joints (95, 85) and deformable in dependency on stresses to which said link member (1) is subjected caused by the weight of the load. The elastically deformable area (13) together with said eyes (11, 12) forms a generally tubular stirrup comprising a passage (130) between two elastically deformable lateral walls (131, 132) and extending along a horizontal axis (x1). In the interior of said passage (130) a measuring beam (14) is installed, which is rigidly connected to both opposite walls (131, 132) and comprises at least one flat surface (140') extending in a direction of said axis, and onto which sensors (51, 52, 53,54) are attached for measuring of extensions or contractions of said beam (14) due to change in distance between the walls (131, 132) when the link member (1) is exposed to stresses in a direction along the vertical axis (z).

Abstract:
The purpose of the invention is to create a hydraulic driving and guiding assembly, namely a pulley, belt pulley or a chain wheel, and in particularly a pulley, which is driven by a hydraulic motor and is intended for unwinding a rope from the drum of a forestry winch, by means of which such unwinding of the rope (5) or a similar longitudinal towing member from the drum could be more efficient, and at the same time also to eliminate loosening of the rope (5) upon being unwound from the drum. For such purposes, a hydraulic driving and guiding assembly of a longitudinal towing member is created, which comprises a main driving member (1), which may rotate around the geometric axis (10) by means of a hydraulic motor (3) and is by means of bearings (41, 42) or similar bearing members embedded within an appropriate casing (2), wherein said main driving member (1) is connected positively in the sense of torque-transmission to a rotor (31) of a hydraulic motor (3), which rotor (31) is embedded within of said casing (2), while the stator (32) of said hydraulic motor (3) is firmly interconnected with said casing (2).
