    Abstract: A damping arrangement (1) for damping radial vibrations in a rotating shaft (2), the damping arrangement (1) comprising at least one first damping element (3), at least one second damping element (4), and a bearing arrangement (5) operably engaging the first damping element (3) and the second damping element (4). The bearing arrangement (5) comprises a first bearing member (6), a second bearing member (7), and a reference (8). The first bearing member (6) is rotatably mounted on the shaft (2) so that radial movement of the shaft (2) is transferred to the first bearing member (6), and is operably connected to the second bearing member (7) by the first damping element (3) and by a first steering structure (9). The first steering structure (9) allows only reciprocating movement of the first bearing member (6), and the shaft (2), in a first radial direction (D1), and the first damping element (3) dampens the reciprocating movement in the first radial direction (D1) with respect to the second bearing member (7). The second bearing member (7) is operably connected to the reference (8) by the second damping element (4) and by a second steering structure (10) allowing only reciprocating movement of the second bearing member (7), the first bearing member (6), and the shaft (2), in a second radial direction D2. The second damping element (4) dampens the reciprocating movement in the second radial direction (D2) with respect to the reference (8).

    Abstract: A shock absorber includes: a shock absorber main body that has an outer tube and a rod movably inserted into the outer tube and can extend and contract; a main passage and a sub passage that communicate in parallel two working chambers provided in the shock absorber main body; a main damping force generation element provided in the main passage; and a sub damping force generation element provided in the sub passage. The main damping force generation element has only a main valve that opens and closes the main passage. The sub damping force generation element has an orifice provided in series with the sub passage, and a sub valve that opens and closes the sub passage and has a valve opening pressure lower than that of the main valve.

    Abstract: The present disclosure relates to a shock absorber, in more detail, a damping force controlling shock absorber of which a damping force characteristic can be appropriately adjusted. A damping force controlling shock absorber according to the present disclosure includes: a cylinder formed in a double structure of an inside and an outside, having an internal space divided into a compression chamber and a rebound chamber by a piston valve, and having a reservoir chamber in an external space; a compression solenoid valve mounted on the cylinder; a rebound solenoid valve mounted on the cylinder; and a check valve disposed in the rebound solenoid valve, and opening and closing a channel connecting the reservoir chamber and the rebound chamber.

    Abstract: A dynamic damper for suppressing vibration generated by a gear attached to a rotation shaft, the dynamic damper, includes: a mass body that is disposed inside a rotation shaft having a hollow shape and extends along a shaft center of the rotation shaft; and an elastic body that couples the mass body to the rotation shaft. Further, a flow path for lubricating liquid to flow is provided between an inner peripheral surface of the rotation shaft and the mass body, and the flow path is formed by the inner peripheral surface of the rotation shaft at an axial position where the elastic body is disposed.
