１はストツパーである。 Fig. 1 is a partially cutaway front view of a conventional hydraulic shock absorber for a vehicle.A piston rod 3 of the hydraulic shock absorber has a piston 2 slidably fitted into a cylinder 1 connected to an axle. The upper end of the piston rod 3 is connected to the vehicle body via a telescopic annular elastic body 5, and a lid 6 is provided on the upper surface of the elastic body 5 to seal it. A variable volume oil chamber 7 in which the upper surface of the body 5 is a part of the wall surface.
When this hydraulic shock absorber expands and contracts under the load of the vehicle body, a portion of the oil sealed in the chamber is accommodated. Note that the force applied to the elastic body 5 is reduced by an auxiliary metal spring 8 for suspending the vehicle body stretched between the piston rod 3 and the cylinder 1. 9 is a flexible film provided on the upper surface of the elastic body 5 to prevent the elastic body 5 from dissolving in oil; 10 is a ball bearing;
1 is a stopper.

する欠点があつた。 In this structure in which the elastic body 5 is a part of the peripheral wall and has a variable volume sealed chamber, in order to prevent the elastic body 5 from dissolving in oil, a flexible membrane 9 is provided on the upper surface of the elastic body 5, and a hydraulic shock absorber is also provided. When the elastic body 5 expands and contracts under the load of the vehicle body, the elastic body 5 also deforms accordingly, requiring an elastic force sufficient to support the vehicle body.Furthermore, it has the disadvantage of requiring replacement due to deterioration. It was hot.
本発明は、このような従来の欠点を除去したも
ので、以下本発明の一実施例を図面により詳細に
説明する。 The present invention eliminates these conventional drawbacks, and one embodiment of the present invention will be described in detail below with reference to the drawings.

室１９を形成したものである。 FIG. 2 is a partially cutaway front view showing an embodiment of the hydraulic shock absorber for a vehicle according to the present invention, and the same parts as in FIG. 1 are given the same reference numerals. That is, a sub-piston 12 is fixed to the upper end of the piston rod 3 and slidably fitted into the cylindrical body 13, and an oil seal 14 is provided on the sub-piston 12, and a seal is formed between the bottom surface of the cylindrical body 13 and the bottom surface of the sub-piston 12. A spring 15 that presses the piston 12 upward is stretched between the cylindrical body 1 and the cylindrical body 1.
The inner surface of an elastic body 16 such as a normal rubber formed in an annular shape is baked on the outer peripheral surface of the vehicle body 3, and the outer surface of the elastic body 16 is baked and fixed to a cylindrical outer wall 17 fixed to the opposite side of the vehicle body. In addition, a lid body 1 is attached to the upper end of the cylindrical body 13.
8 to seal the upper part of the cylindrical body 13 to form a variable volume oil chamber 19 with the upper surface of the piston 10 as part of the wall surface.

行う。 Therefore, if the load on the car body increases, the elastic body 1
6 and rod 3, the piston 2 connects to the cylinder 1.
Accordingly, the oil in the lower chamber in the cylinder 1 opens the annular valve 2a in the piston 2 and flows into the upper chamber, and at the same time oil corresponding to the volume of the piston rod 3 inserted into the cylinder 1 flows downward. The oil flows into the oil chamber 19 through the oil hole 4 and moves while pushing down the sub piston 12 against the spring 15. Additionally, when the load on the vehicle body decreases, the pressure in the lower chamber decreases, so the oil in the oil chamber 19 moves up the piston 12 by the springs 8 and 15, flows into the lower chamber through the oil hole 4, and the oil in the oil chamber 19 flows into the lower chamber through the oil hole 4. At the same time as the rod 3 is moved upward with respect to the cylinder 1, oil flows into the lower chamber through a narrow passage (not shown) in the piston and acts as a buffer.

果がある。 As described above, according to the present invention, since the oil chamber serving as the overflow oil storage chamber is constituted by the auxiliary piston, the mechanical configuration is extremely simple and can be made at low cost. Since the body is not used as part of the containment chamber, there is no need to worry about replacing it due to deterioration.
Moreover, the elastic body used in the present invention is for holding the shock absorber, and there is no fear that it will be dissolved by oil, and an ordinary hard body can be used. Note that the present invention has the advantage that it can also be used for vehicle height adjustment by changing the oil pressure in the accommodation chamber using an external reservoir or supply source.
