Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a spring seat for a hydraulic shock absorber used in motorcycles and the like.

(Prior Art) In a hydraulic shock absorber using an offset type suspension spring, etc., in order to avoid interference between the dust cover, suspension spring, and cylinder caused by fluctuations in the distance between the center of the cylinder and the center of the suspension spring, A spring seat that supports the suspension spring is provided above the cylinder separately from the rubber seat, and the upper end of the rubber seat is fixed to this spring seat.

In this case, in order to fix the dust cover to the spring seat, as shown in FIG. flange portion 53 on the lower surface of the central portion of
A dust cover guide 53 having a cylindrical shape having a diameter a is fixed, and a claw portion 56 of a dust cover 55 is engaged with a groove 54 formed in the cylindrical portion of the dust cover guide 53.

(Problems to be Solved by the Invention) Since the spring seat 50 as described above is formed separately from the dust cover guide 53, the dust cover guide 53 must be fixed to the spring seat 50 by welding or the like. .

Furthermore, in this case, in order to prevent water from accumulating in the recess 50a on the upper surface of the spring seat 50, it is necessary to provide a water drain hole 57 in the spring seat 50 and the dust cover guide 53. When fixing the guide 53 by welding, it takes time and effort to align the phases of each drain hole 57, and manufacturing is difficult.

(Means for Solving the Problems) In order to solve the above problems, the present invention includes cutting out a part of the circumferential surface of the spring seat while holding the inner circumferential side.
By bending this notch, a hanging piece is formed and at the same time a drain hole is formed, and when the upper end of the dust cover is secured to the inner circumferential side of this hanging piece, water can be drained through the drain hole. I made it possible.

(Example) An example of the present invention will be described below based on the accompanying drawings.

FIG. 1 is a sectional view of a main part of a hydraulic shock absorber equipped with a spring seat according to the present invention.

A spring seat 1 is a stop lever 3 of a piston rod 2 attached to a piston (not shown).
It is placed and fixed on the top surface of the spring seat 1.
The upper part of the is attached to the vehicle body via a mount rubber.

A spring receiving part 4 is formed on the outer peripheral surface of the spring seat 1, and the upper end of the suspension spring 5, which is stretched between the spring receiving part 4 and the spring receiving part provided on the lower outer periphery of the cylinder, is covered with a rubber sheet. It is supported through 6.

Further, a recess 7 is formed inside the spring seat 4 of the spring seat 1, and the recess 7 is cut out at a plurality of places while holding the inner circumferential side, and the notch is bent downward to form a hanging piece. At the same time as 8 is formed, a drain hole 9 is formed.

A locking groove 10 is formed in the hanging piece 8, and a claw portion 11a formed at the upper end of the dust cover 11 is locked in this locking portion 10. Cover between the tops.

In addition, in order to fix the dust cover 11 to the spring seat 1, it may be fixed to the inside of the hanging piece 8 as shown in FIG. It may be fixed to the outside of 8.

(Effects of the invention) As explained above, according to the invention, a part of the circumferential surface of the spring seat is cut out while holding the inner circumferential side, and the hanging piece is formed by bending this notch. Since the upper end of the dust cover is locked to this hanging piece, there is no need to provide a dust cover guide, and the water drain hole formed in the spring seat and the water drain hole formed in the dust cover guide can be easily connected to each other. The work of aligning the phases and the subsequent work of fixing the dust cover guide to the spring seat by welding can be omitted, improving productivity.

Furthermore, by cutting out a part of the circumferential surface of the spring seat and bending this notch to form a hanging piece that fixes the dust cover, a drainage hole can also be formed at the same time, which is effective in terms of work efficiency. It is.

[Brief explanation of the drawing]

FIG. 1 is a sectional view of a main part of a hydraulic shock absorber equipped with a spring seat according to the present invention, and FIG. 2 is a sectional view showing a conventional spring seat. In the figure, 1 is a spring seat, 3 is a suspension spring, 7 is a notch, 8 is a hanging piece, 10 is a locking part,
11 is a dust cover, and 11a is a claw portion.

Claims (1)

[Scope of utility model registration request] In a spring seat that supports the upper end of a suspension spring of a hydraulic shock absorber, a part of the circumferential surface of the spring seat is cut out while holding the inner circumferential side, and this cutout is bent to form a hanging piece. A spring seat characterized in that a water drain hole is formed, and water can be drained from the water drain hole when the upper end of the dust cover is locked to the inner peripheral side of the hanging piece.
