Abstract

PURPOSE:To faciltate car adjustment and perform quick car height adjustment by screwing a mount base and a lock nut in a bearing housing that externally engages and holds the upper mounting position of a buffer. CONSTITUTION:A mount base 4 and a lock nut 5 are externally engaged and screwed in a bearing housing 3 so as to freely swing. The mount base 4 is mounted on a car body frame using bolts. On the other hand, the bottom metal 7 at the bottom of a cylinder 1 is supported on a rear fork through a link. As a result, the mount base 4 mounted on the car body frame is elevated along the male screw on the external surface of the bearing housing 3 and the buffer length, that is , the length between an axle and the car body frame is varied by first loosening the lock nut 5 and rotating a tool while making contact to a pawl-shaped section on the upper end of the bearing section 3.

In general, a hydraulic shock absorber that supports the rear wheel of a motorcycle by a shock absorbing method slides inside a cylinder [7] and pulls out the rod of the piston equipped with a damping force generation mechanism to the outside of the cylinder, and attaches the rod to the piston rod side. A spring is interposed between a fixed spring receiver and a spring receiver provided on the outer periphery of the cylinder. Conventionally, this type of shock absorber has been able to change the set load of the spring depending on the road condition using screw type, cam type, hydraulic type, etc., and while this improves the shock absorbing effect, it also reduces the set load of the spring. The changes caused the vehicle height to change, making it difficult to maintain a constant vehicle height.

The set load will be large. After that, turn the hook-shaped stopper (19) to lower it along the outer periphery of the upper metal (16), and attach the stopper (19) to the spring receiver (20).
) will stop if the bottom ends of the cylinders come into contact with each other. As described above, when the set load of the spring (21) increases, the amount of depression of the vehicle decreases due to the spring reaction force of the spring (21), and therefore the vehicle height increases. The amount of change in vehicle height can be determined by first loosening the lock nut (34), then applying a tool to the claw-shaped portion at the upper end of the bearing housing (27) and rotating it. The bearing housing (27) is lowered along the external thread on the outer circumferential surface to shorten the length of the shock absorber and the length between the pick axle and the vehicle body frame.

In the hydraulic shock absorber having the above configuration, the spring (4
The set load in step 1) is changed by turning the spring holder (39) and moving it up and down along the external thread on the outer periphery of the cylinder case (35). For example, if the spring holder (39) is moved downward, the set load of the spring (41) will increase. Once a certain set load is obtained, the lock nut (65) can be tightened to fix the position of the spring receiver (39). As described above, when the set load of the spring (41) increases, the amount of sinking of the vehicle decreases due to the spring reaction force of the spring (41), and therefore the vehicle height increases. The adjustment method for correcting the amount of change in vehicle height is as simple as in the previous embodiment, by rotating the first bearing housing (52) and lowering the mount base (57) to shorten the length of the shock absorber. It is something.

According to the present invention, as described above, even though the conventional hydraulic shock absorber is simply improved, the vehicle height can be adjusted steplessly and easily when it is attached to a motorcycle. . Furthermore, since the means for changing the spring set load can be applied to any screw type, cam type, or hydraulic shock absorber, it is possible to quickly adjust the vehicle height after changing the spring set load depending on the road condition. It is now possible to implement it, and the effects are significant.
