Problems solved by technology

[0004] However, since the rebound stopper 700 made of urethane has high hardness, the initial compression amount (deformation amount) at the time of impact is small, so there is a problem that the impact sound is loud

Embodiment 1）

[0057] refer to Figure 1 to Figure 6 The rebound stopper in Embodiment 1 of the present invention will be described.

[0058]

[0059] refer to Figure 1 to Figure 4 The structure of the rebound stopper in Embodiment 1 of the present invention will be described.

[0060] The rebound stopper 100 of this embodiment is used for a suspension of an automobile or the like. That is, if Figure 4 As shown, the rebound limiter 100 is installed on the outer periphery of a rod (piston rod) 500 which is arranged in a cylinder 600 of the suspension and can reciprocate therein. In addition, the rebound stopper 100 has one end facing the rebound plate 510 provided on the rod 500 and the other end facing the rod guide 610 provided on the inner periphery of the cylinder 600 as a member to be impacted. In addition, the rod guide 610 functions as a bearing for the rod 500 .

[0061] In a normal state, one end of the rebound limiter 100 is in contact with the rebound plate 510 , and the o...

Embodiment 2）

[0078] refer to Figure 7 ~ Figure 11 A rebound stopper according to Embodiment 2 of the present invention will be described. Figure 7 is a perspective view of the rebound stopper of the present embodiment, Figure 8 ~ Figure 10 is a sectional view of the rebound stopper of this embodiment. Figure 11 It is a schematic sectional view showing the installation state of the rebound stopper of this embodiment. here, Figure 8 It is a cross-sectional view cut along the central axis of the rebound stopper and not passing through the through-hole 220 described later, corresponding to the Figure 9 Figure cut off at the BB position in . Figure 9 It is a sectional view cut along a position perpendicular to the central axis of the rebound stopper and passing through the through hole 220, which is equivalent to Figure 8 Figure cut off at the AA position in the middle. Figure 10 It is a cross-sectional view cut along the central axis of the rebound stopper and passing through th...

Embodiment 3）

[0091] Figure 12Example 3 of the present invention is shown. In the above-mentioned embodiment 2, the case where the through-holes are respectively arranged at the same position in the circumferential direction for each annular groove for any annular groove is shown, but in this embodiment, it is shown that a plurality of holes respectively provided in adjacent annular grooves. The through holes are arranged at positions shifted in the circumferential direction. Except for the arrangement positions of the through-holes, other structures and functions are the same as those of the second embodiment, so they will be briefly described.

[0092] In the rebound stopper 200a of this embodiment, a plurality of (four in this embodiment) annular grooves are formed at intervals in the direction in which the rod extends (that is, the axial direction) on the outer peripheral side thereof, and the overall The shape is a bellows tube shape. Hereinafter, these annular grooves are referred...

Abstract

The present invention provides a rebound stop that reduces impact sound. The rebound limiter is installed on the outer periphery of the rod (500) capable of reciprocating movement in the cylinder (600), one end of which is opposite to the rebound plate (510), and the other end is opposite to the rod guide (610), The rebound stopper (100) is a roughly cylindrical part made of urethane, and when the rod (500) moves toward the direction in which the rebound plate (510) and the rod guide (610) face each other, the other end and the rod guide (610) touches and is compressed by the rebound plate (510) and rod guide (610), thereby absorbing the impact energy, has a plurality of protrusions at both ends, and the protrusions at one end and the protrusions at the other end are configured offset in the circumferential direction.

Description

technical field [0001] The present invention relates to rebound stoppers. Background technique [0002] Conventionally, in suspensions of automobiles, etc., rebound stoppers are provided in order to absorb the energy of impacts received when the vehicle body is suspended. As the rebound stopper, a substantially cylindrical member made of urethane is known (see Patent Documents 1 and 2). refer to Figure 14 The rebound stopper in the above conventional example will be described. Figure 14 It is a schematic sectional view showing the installation state of the rebound stopper in the conventional example. [0003] In the rebound limiter 700, one end 701 of it abuts against the rebound plate 510 provided on the rod 500, and when the rod 500 is extended to a certain length, its other end 702 contacts the rod guide provided on the inner periphery of the cylinder 600. 610 A touch occurs. Furthermore, the rebound stopper 700 is clamped and compressed by the rebound plate 510 and ...
