JPH0882334A - Shock absorber spring fitting/removing tool - Google Patents

Abstract

PURPOSE: To provide a tool that can fit/remove the spring of a shock absorber safely and easily. CONSTITUTION: A shock absorber spring fitting/removing tool is provided with a shaft holder 1 inserted through the upper part bolt hole 51 of a shock absorber body 50 and provided with shaft holes 11 on both sides, two shafts 2 provided at the lower ends with hooks 22 for locking a spring 6, and washers 3 and butterfly nuts 4 screwed with the thread parts 21 of the shafts 2. The shafts 2 passed through the holder 1 are screw-fed upward by screw-fastening the butterfly nuts 4 so as to compression-hold the spring 6 locked by the hooks 22. A spring receiving member 7 is thereby placed in the free state so as to be pulled out or insert-fitted. The butterfly nuts 4 are loosened to screw-feed the shafts 2 downward. The compression of the spring 6 is thereby released to fit/remove the spring 6.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool used for attaching and detaching a shock absorber spring.

[0002]

2. Description of the Related Art Replacement of a shock absorber spring used in a suspension of a two-wheeled four-wheeled vehicle in the related art is difficult and dangerous, and the mechanic is currently skilled in the art.

[0003]

Therefore, according to the present invention, the spring of the shock absorber can be attached and detached safely and easily,
It is intended to provide a tool that can be attached and detached by a general person.

[0004]

For this reason, the present invention is used for attaching and detaching a shock absorber spring, and is a shaft having a shaft hole formed on both sides thereof, which is inserted into a bolt hole in an upper portion of a shock absorber body. It consists of a holder, two shafts with a threaded part formed at the top and hooks for locking the shock absorber spring at the lower end, and a nut such as a wing nut screwed into the threaded part of the shaft. By screwing the shaft passed through the holder by screwing in the upward direction and compressing and holding the spring locked by the hook, the spring receiving member that receives the spring is pulled out or inserted in a free state, and the nut is loosened to loosen the shaft. The sprinkle can be attached and detached in a free state by feeding the screw downward and releasing the compression of the spring. There.

[0005]

[Operation] When removing the spring of the shock absorber, insert the shaft holder into the bolt hole of the shock absorber body, pass the shaft through the shaft hole, hook the lower part of the spring with a hook, and screw the nut with the threaded part of the shaft. The shaft is screw-fed upwards and the spring is compressed and held.In this state, after removing the spring receiving member that is in a free state, the shaft is screw-fed downwards by loosening the nut, Pull out the spring that has become a weak impact.

When mounting the spring, the spring is inserted and locked by the hook of the shaft, the nut is screwed and the spring receiving member is arranged while the spring is compressed and held, and then the nut is loosened. The spring is attached by removing the hook from the shaft and the holder can be removed from the shock absorber body.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The illustrated embodiments of the present invention will be described below. In the present example shown in FIG. 1, 1 is a shaft holder, which is a bolt hole 5 in the upper part of the shock absorber body 50.
It has a shaft hole 11 formed on both sides thereof. Reference numeral 2 denotes a shaft, which has a male screw portion 21 formed on an upper portion thereof and a hook 22 for locking the shock absorber spring 6 provided on a lower end thereof. 3 is a washer and 4 is a wing nut.

When removing the spring 6 of the shock absorber, first remove the shock absorber 5 from the vehicle body, insert the shaft holder 1 into the bolt hole 51 and pass the shaft 2 into each shaft hole 11 as shown in FIG. The lower part of the spring 6 is locked by the hook 22, and the wing nut 4 is screwed through the washer 3 by the male screw portion 21 of each shaft 2.

Then, by strongly tightening the respective wing nuts 4, the respective shafts 2 are screw-fed upward and the springs 6 are compressed and held by the hooks 22, as shown in FIG. In this state, the lower end spring receiving member 7 is removed from the shock absorber body 50, and then the wing nuts 4 are loosened as shown by phantom lines in FIG. 3 so that the shaft 2 is screwed downward. As shown in FIG. 3, the spring 6 which has been fed and is in a free state
Remove from 2 and pull out. The shaft 2 may be removed from the holder 1 and the spring 6 may be removed.

When mounting the springs 6, the springs 6 are attached in the reverse order of their removal. As shown in FIG. 3, the springs 6 are inserted into the shock absorber main body 50 and the lower portions are engaged with the hooks 22 of the respective shafts 2. Stop, then wing nut 4
After the spring receiving member 7 is inserted into the lower end of the shock absorber body 50 while the spring 6 is being compressed and held, the wing nut 4 is loosened and the hook 22 is removed from the spring 6, whereby the spring 6 is released. It is installed. Then, the shaft 2 may be removed from the holder 1, and the holder 1 may be removed from the bolt hole 51 of the shock absorber body 50.

As described above, according to this embodiment, since the spring 6 can be compressed and held by screwing the wing nut 4, the spring receiving member 7 can be easily attached and detached, and thus the spring 6 can be removed from the shock absorber main body 50. It can be done easily. Also, this spring 6
Since it is held by the shaft 2 of the book, it can be operated safely.

Although this example is constructed as described above, the present invention is not limited to this. For example, regardless of the shape of the shaft holder having the shaft holes provided on both sides, it suffices that the shaft holder can be inserted into the bolt holes in the upper portion of the shock absorber body. Further, the structure of the shaft attached to the shaft hole of the holder is not limited, and a screw portion may be formed on the upper portion and a hook may be formed on the lower end. The kind of nut screwed onto the threaded portion of the shaft is also appropriate.

[0013]

According to the present invention, since the spring can be compressed and held by the two shafts by screwing the nut, the spring receiving member can be easily attached and detached, and the spring can be removed from the shock absorber body.
Since the effect of being easy and safe to insert is great and no skill is required, the shock absorber spring can be easily replaced even by a general worker.
