Embodiment Construction

[0017] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0018] will be described below figure 1 and figure 2 A first preferred embodiment of the invention is shown in .

[0019] Such as figure 1 As shown, the single-cylinder hydraulic shock absorber in the first preferred embodiment of the present invention is provided with a cylinder body 11 and an air chamber 2, wherein the cylinder body 11 is made of aluminum, and the air chamber 2 is used as an air spring , and is provided in the upper end side of the cylinder 11 . However, only a part of the air chamber 2 is shown in the figure.

[0020] Such as figure 2 As shown, the entire periphery of the upper end, which is the opening end of the cylinder body 11, is bent inward by the caulking process. An oil seal is fixed to the upper end face of the cylinder 11 by means of a caulked end 11a bent inward, the upper end opening of the cylinder 11 being closed...

Abstract

A single-cylinder hydraulic shock absorber ( 1 ) is provided with an air chamber ( 2 ) which is formed by a flexible tubular member ( 2 a) connected air-tightly to each of an upper part of a cylinder ( 11 ) and a piston rod ( 12 ) to enclose air therein. The air chamber ( 2 a) includes at the lower end a tubular protector ( 23 ) engaged to an upper part of the cylinder ( 11 ). A flexion part ( 23 a) in an upper end of the protector ( 23 ) is retained on an upper end surface of the cylinder ( 11 ). A seal member ( 3 ) located between the flexion part ( 23 a) and the upper end surface includes a cored bar (33) fixed on the upper end surface of the cylinder ( 11 ) and having a dust lip ( 31 ) and an oil lip ( 32 ), and a circular air seal ( 5 ) interposed between the cored bar and the flexion part.

Description

technical field [0001] The present invention relates to improvements in single cylinder hydraulic shock absorbers with air springs for use in vehicle suspensions. Background technique [0002] In Japanese Unexamined Patent Publication JP2004-332747A there is disclosed a single-cylinder hydraulic shock absorber used in a vehicle suspension, which has an air chamber at its upper portion. [0003] In this example, the air chamber is provided with a rolling diaphragm which is airtightly connected on one end side to a piston rod and on the other end side to a cylinder side, thereby Keep the air chamber airtight. Contents of the invention [0004] With the cylinder block made of aluminum, the weight of the hydraulic shock absorber is considerably reduced. However, when the rolled diaphragm is hermetically connected to the aluminum cylinder by welding, the strength of the aluminum material is lowered, which is disadvantageous. [0005] In view of the foregoing, there is a need...
