Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, the present invention provides a technical solution: the utility model provides a damping shock absorber for motorcycle, includes first cylinder body 1, the inner chamber sliding connection of first cylinder body 1 has first piston 2 and second piston 5, one side fixedly connected with first piston rod 3 of first piston 2, the left side of first cylinder body 1 is fixed with the ring pipe 12 of cup jointing in the first piston rod 3 outside, the inboard of ring pipe 12 evenly runs through there is gas pocket 17, the right side of first cylinder body 1 is linked together through blast pipe 10 and ring pipe 12, the right side intercommunication of first cylinder body 1 has intake pipe 8, the mouth of pipe department of intake pipe 8 is equipped with first check valve 9, one side of blast pipe 10 is equipped with second check valve 11, second piston 5 is connected on the inner chamber right side through second spring 6 with first cylinder body 1.

Specifically, the inboard of annular pipe 12 is fixed with annular ring 14, the inboard of annular ring 14 is fixed with annular ring 15 through the screw, the inboard of annular ring 15 is fixed with toper rubber circle 16, the inboard close fitting in the outside of sleeve 13 of toper rubber circle 16 for scrape off the earth dust in the first piston rod 3 outside.

Specifically, a sleeve 13 sleeved outside the first cylinder 1 is fixed on one side of the annular pipe 12, and the sleeve 13 is fixed on the outside of the first cylinder 1 through a bolt, so that the annular pipe 12 is fixed on the outside of the first cylinder 1.

Specifically, the right side of the inner cavity of the first cylinder body 1 is fixed with a protruding column 7 for limiting the second piston 5 and preventing the second spring 6 from being damaged.

Specifically, the first piston 2 is connected with the second piston 5 through a first spring 4, so as to increase the damping effect.

Specifically, the number of the conical rubber rings 16 is two, so that soil can be scraped from the outer side of the first piston rod 3 conveniently.

The working principle is as follows: when the motorcycle runs on a bumpy road section and is subjected to vibration, the first piston rod 3 pushes the first piston 2 to move, a sealed space formed between the first piston 2 and the second piston 5 is filled with gas, the second piston 5 is pushed to move by gas compression, the second spring 6 is compressed when the second piston 5 moves, the gas in the first cylinder body 1 is discharged when the second piston 5 moves, at the moment, the first one-way valve 9 is in a closed state, the exhaust pipe 10 is in a conducting state, so that the gas is discharged from the gas discharge pipe 10 into the annular pipe 12, the gas is injected outward through the gas holes 17 at a high pressure, the dust on the outer side of the first piston rod 3 is blown off, the aperture of the air hole 17 is less than 0.5mm, so that the gas can form high-pressure jet, when the second piston 5 moves to touch the convex column 7, the gas between the first piston 2 and the second piston 5 starts to be compressed, thereby playing a role of pneumatic shock absorption. When no pressure is applied, the second spring 6 rebounds the second piston 5, at this time, the first check valve 9 is in a conducting state, and the second check valve 11 is in a closed state, so that the air inlet pipe 8 sucks air into the first cylinder 1.
