た。 The oil chamber in this type of shock absorber is formed between a lid (generally called a mount cap) that seals the upper end of an outer frame fixed to the vehicle body and the upper surface of a cylindrical elastic body. , the lid body is fixed to the outer frame body by welding or the like. However, if the lid body has a non-disassembly structure, if the oil pressure in the oil chamber increases excessively and exceeds the allowable pressure, the abnormal situation cannot be detected promptly, and the shock absorbing performance is forced to deteriorate. , and may cause accidents. Another drawback was that repair costs were high if the buffer broke down.

る。 This invention is an improvement to solve the above-mentioned drawbacks of the conventional one.The lid body is removably attached via a circlip, and when the oil pressure in the oil chamber exceeds the allowable pressure, the circlip comes out and no more pressure is applied. This feature is characterized in that it prevents the pressure from being applied, so that abnormal situations can be discovered quickly, and can be easily repaired by simply replacing the lid.

である。 A piston rod 2 of a hydraulic shock absorber has a piston (not shown) slidably fitted into a cylinder 1 connected to the shaft of a rear wheel of a four-wheeled vehicle. Inner frame bodies 3-1 and 3-2 are attached coaxially to the rods with nuts 4, and a cylindrical outer frame body 5, which is located outside the inner frame bodies and is fixed to the vehicle body, is attached to the inner frame body. arranged coaxially, the inner frame body 3-
1, 3-2 and the outer frame 5 are connected by a cylindrical elastic body 6 inserted between both frames, and the inner frame 3-1
The piston rod 2 is inserted through the bearing 7 inside the
The body suspension spring 1 is placed between a spring receiver 9 which is integrally structured with the cylinder body 8 fixed to the cylinder 1 and a spring receiver 10 which is fixed to the cylinder 1.
In a hydraulic shock absorber for car body suspension having a structure in which a shock absorber 1 is stretched, a circlip groove 12 is provided on the inner wall at the upper end of the outer frame 5, and a circlip 13 is fitted into this groove to removably attach a cover 14. The lid body 14 is attached so that the oil chamber 15 is formed by the oil chamber 15 and can be removed.
In other words, when a circlip with a square cross section is used, it will elastically deform and come off when it is subjected to pressure above a certain level, whereas a circlip with a circular cross section can be easily made to dimensions that provide the above effect. Can be done. A flexible film 16 is provided on the upper surface of the elastic body 6 to prevent the elastic body from dissolving in oil, and the inner end of this flexible film is attached to the inner frame 3-2. The outer end portion thereof is fitted into the lower end of the lid body 14 in a concave and convex manner. In addition, the lid body is provided with an outflow inlet 17 for vehicle height adjustment oil.
It is connected to a high pressure oil source by a conduit (not shown). In the figure, 18 is a damper rubber and 19 is a cover.

安価につく。 In the shock absorber having the above structure, the piston rod 2
When a pressure greater than the allowable pressure is generated in the upper oil chamber 15, the circlip 13 fixing the lid body 14
comes out of the clip groove 12 due to the pressure. When the circlip comes off, naturally no more pressure is applied to the oil chamber 15, so the occurrence of abnormal pressure can be detected. Therefore, damage to the lid 14 and the shock absorber itself can be reduced. In addition, if the shock absorber is damaged due to such a situation and the lid needs to be repaired, the lid 14 has a structure that allows it to be disassembled, so not only can the lid be easily replaced, but most It is only necessary to replace the lid, and there is no need to replace the entire buffer. Therefore,
Repair costs are also much lower than conventional non-disassembly structures.

ものである。 As mentioned above, this device has the advantage of making the so-called mount cap of the shock absorber removable via the circlip, which allows the mount cap to be easily installed and removed, and also to immediately prevent abnormal pressure from occurring. The damage to the shock absorber that can be detected can be significantly reduced, and the repair cost can be reduced by simply replacing the mount cap, making it highly safe and economical.
