Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spring load adjusting device for a hydraulic shock absorber mainly used as a rear suspension for two-wheeled motor vehicles.

The applicant of the present invention has previously proposed a device of this type that includes a coil spring on the outer periphery of a shock absorber body and a rotary adjuster that supports the spring from the lower surface, and a rotary adjuster that supports the spring from the lower surface. a pivot ring having an engaging operating lever;
In this way, by reciprocally rotating the ring via the lever, the adjuster is rotated in one direction to adjust its height, thereby changing the spring load on the spring. However, in this case, the operating lever is likely to protrude outward and become a hindrance to some extent, which is a disadvantage. The purpose of the present invention is to obtain a device free of such inconveniences, and includes a coil spring 2 on the outer periphery of a shock absorber body 1, and a rotary adjuster 3 that supports the spring 2 from the bottom surface. At the same time, the operating lever 5 is engaged with the outer periphery of the adjuster 3 via the ratchet mechanism 4.
In the type equipped with a rotating ring 6 having a rotary ring 6, the lever 5 is composed of an inner member 5a fixed to the ring 6, and an outer member 5b bendably connected to the inner member 5a via a pin 7, The outer member 5b has a slidable ring 8 on the outer periphery of the inner end, an enlarged head 9 on the outer end, and a rubber or other elastic member 1 on the middle outer periphery.
0.

The adjuster 3 is of a type that engages with a stopper 3b on the lower side via a cam 3a on the lower surface, and its height is adjusted by the cam surface of the cam 3a. Ratchet claw 4
a and a pawl hole 4b on the side of the adjuster 3. The elastic member 10 is generally made of cylindrical rubber.

To explain its operation, the outer member 5b is fixed to the pin 7
When the lever 5 is raised around the pin 7 as an axis to align its axis with the inner member 5a, the lever 5 as a whole is increased in length and prepared for operation, and at this time the ring 8 at the inner end is pressed by the elastic member 10 on the outside and seats on the opposing end face of the inner member 5a, thus maintaining it in a stable straight position. Next, when the lever 5 is bent around the pin 7 as an axis, the ring 8 is pressed by the end face and moves backward against the elastic member 10 once to allow the bending, and then, at the bent position, the ring 8 is pressed by the elastic member 10 and seats on the opposing side face of the inner member 5a, thereby becoming stable. Thus, the lever 5
The overall protrusion length decreases.

As described above, according to the present invention, the operating lever 5 is bendable, and is formed to be relatively long so that the operation is easy and can be bent as necessary without getting in the way. Both members 5 constituting
The members a and 5b are stable in the straight position and the bent position, respectively, and can be easily used.The structure includes a ring 8 at the inner end and an elastic member 10 at the outer end of the member 5b. It is simple to just provide the elastic member 10, and furthermore, the elastic member 10 has the advantage that it can be constructed of, for example, a rubber tube and used as a grip lever.
