Patent number: 11933020Abstract: A storage part of a construction machine stores an operation target which is set as a target of an operation of the construction machine for moving a specific portion of the construction machine to a target position set as a destination to which the specific portion moves. A calculation part calculates an index value which serves as an index indicating a deviation between the operation target and an actual state of the construction machine. A control device is configured to cause a vibration applying device to perform a first vibration applying operation when the index value satisfies a predetermined first condition, and to cause the vibration applying device to perform a second vibration applying operation when the index value satisfies a predetermined second condition different from the first condition.Type: GrantFiled: March 18, 2019Date of Patent: March 19, 2024Assignee: KOBELCO CONSTRUCTION MACHINERY CO., LTD.Inventors: Kiyokazu Tanaka, Reona Takamura

Patent number: 5765673Abstract: An engaging apparatus is provided that includes: outer and inner support members having respective splines that are opposed to each other in a radial direction thereof, and being rotatable relative to each other; a plurality of outer friction plates engaging with the spline of the outer support member; a plurality of inner friction plates alternately superposed on the outer friction plates and engaging with the spline of the inner support member; and a hydraulic piston mechanism for compressing a stack of the outer and inner friction plates. A spring member is inserted between circumferentially opposed faces of a driven set of the friction plates and a spline of the corresponding support member. The spring member is formed by bending an elastic material at an axially intermediate point thereof to have a long side and a short side with a circumferential spacing left therebetween.Type: GrantFiled: August 28, 1996Date of Patent: June 16, 1998Assignee: JATCO CorporationInventors: Hiroyuki Nishiyama, Fumikazu Takaoka, Kiyokazu Tanaka

Patent number: 5653321Abstract: According to the clutching device of the present invention, a flexible member, which uniformly forces a plurality of friction plates almost in the circumferential direction, is inserted between edge faces, of fixed friction plates, to which no load is applied at the time of engagement, and a spline face that is opposite to the edge faces. The insertion position is selected at such a location where the rotational direction of a rotary body is diagonally upward and toward the center. Since a load on and a degree of distortion of the flexible member are small, the flexible member can be compactly made and can have a simple design, and the mounting structure on the spline side is also simpler.The clutching device with this structure effectively prevents the vibration of friction plates, requires only a small number of components. And additional components are easily installed and removed.Type: GrantFiled: July 26, 1995Date of Patent: August 5, 1997Assignee: Jatco CorporationInventors: Fumikazu Takaoka, Hiroyuki Nishiyama, Kiyokazu Tanaka
