REBOUND SPRING STRUCTURE

Номер: WO2018078896A1
Автор: MURAGUCHI Nobuyuki, YAMAMOTO Takao, SENOU Naoki
Принадлежит:

A rebound spring structure is provided with a rebound spring 110, a lower end rebound collar 120 for holding one end of the rebound spring 110, and an upper end rebound collar 130 for holding the other end of the rebound spring 110, and is disposed around a rod that moves with respect to a cylinder. The lower end rebound collar 120 is held on a piston rod. In the upper end rebound collar 130, an upper end disc-shaped part 131, which is fitted on the piston rod so as to be movable and regulates movement towards the other end of the rebound spring 110, has recesses 131a for promoting movement towards the circumferential direction of the piston rod.

One embodiment provides a pressure buffer device including: a cylinder that stores fluid; a flow path forming portion that forms a flow path; and an opening-closing portion that opens and closes the flow path of the flow path forming portion. The fluid flows through the flow path forming portion in accordance with relative movement of a rod with respect to the cylinder in an axial direction of the cylinder. The flow path forming portion includes an annular first protruded portion and an annular second protruded portion protruded in the axial direction in opposite sides respectively. The second protruded portion has an axial end located at a radially outer side of the first protruded portion, and a tilt portion formed at least at a part of a radially-inner part of the second protruded portion. 1. A pressure buffer device , comprising:a cylinder that stores fluid;a flow path forming portion that forms a flow path through which the fluid flows in accordance with relative movement of a rod with respect to the cylinder in an axial direction of the cylinder; andan opening-closing portion that opens and closes the flow path of the flow path forming portion, a first protruded portion that is formed annularly to be protruded in the axial direction, to which the opening-closing portion is contacted; and', 'a second protruded portion that is protruded in the axial direction toward a side opposite to the first protruded portion, that has an end in the axial direction located at a radially outer side of the first protruded portion, and that includes a tilt portion tilted with respect to the axial direction and formed at least at a part of a radially-inner part of the second protruded portion., 'wherein the flow path forming portion includes2. The pressure buffer device according to claim 1 ,wherein the tilt portion is arranged at the radially outer side of the first protruded portion.3.

Die Zugstufenfederkonstruktion beinhaltet: eine Zugstufenfeder 110; einen unteren Zugstufenring 120, der so ausgelegt ist, dass dieser ein Ende an einer Seite der Zugstufenfeder 110 hält; und einen oberen Zugstufenring 130, der so ausgelegt ist, dass dieser ein Ende an der anderen Seite der Zugstufenfeder 110 hält, wobei die Zugstufenfederkonstruktion um eine Stange positioniert ist, die so ausgelegt ist, dass sie sich in Bezug auf einen Zylinder bewegt. Der untere Zugstufenring 120 wird von einer Kolbenstange gehalten. Der obere Zugstufenring 130 ist beweglich an der Kolbenstange angebracht. Der obere Zugstufenring 130 weist eine Vertiefung 131a an einem oberen Scheibenabschnitt 131 auf, der so ausgelegt ist, dass die Bewegung der Zugstufenfeder 110 zu der anderen Seite eingeschränkt wird, und die Vertiefung 131a ist so ausgelegt, dass eine Bewegung des oberen Zugstufenrings 130 in einer Umfangsrichtung der Kolbenstange erleichtert wird. The rebound spring design includes: a rebound spring 110; a lower rebound stage ring 120 configured to hold one end to a side of the rebound spring 110; and an upper rebound stage ring 130 configured to hold one end on the other side of the rebound spring 110, the rebound spring structure being positioned about a rod configured to move relative to a cylinder. The lower rebound ring 120 is held by a piston rod. The upper rebound stage ring 130 is movably mounted on the piston rod. The upper rebound stage ring 130 has a recess 131a at an upper disc portion 131 designed to restrict the movement of the rebound spring 110 to the other side, and the recess 131a is configured to allow movement of the upper rebound stage 130 in one Circumferential direction of the piston rod is facilitated.
