Abstract
The invention discloses a motorcycle rear shock absorber with an upper spring, a middle spring and a rear spring. The motorcycle rear shock absorber with the upper spring, the middle spring and the lower spring comprises an outer shell, a piston rod is arranged in the outer shell, an upper mounting sleeve is arranged at one end of the piston rod, a lower mounting sleeve is arranged at the other end of the piston rod, and a damper component and a shock pad are arranged on the piston rod in the outer shell. An adjuster is arranged at one end of the outer shell. The motorcycle rear shock absorber with the upper spring, the middle spring and the lower spring is characterized in that a spring seat pad is arranged on the outer surface of the outer shell, a plurality of springs are arranged on the spring seat pad, and a spring separating plate is arranged between every two adjacent springs. The springs are good in stability and small in bending and deformation amount, and rusting, damage and abnormal sounds caused by the mutual friction of a protection cover, the damper and the springs caused by the bending of the springs are avoided. Meanwhile, the upper spring, the middle spring, the lower spring and the spring separating plates have different colors, the single color of a single spring is replaced after the different colors are combined, the colors are richer and more colorful, and the shock absorber is more artistic in appearance.
Description
Technical field
The invention belongs to the vehicular shock absorber field, specifically, relate to a kind of upper, middle and lower three spring rear shock absorber of motorcycle.
Background technique
The length of motorcycle list spring rear shock absorber spring is the difference with the difference of vibration damper length generally, the external diameter of absorber spring is the difference with the difference of damper external diameter generally, for some slender type vibration dampers, when the ratio of height to diameter of damping spring is big, vibration damper or spring are prone to the bending deflection of spring when compression, cause the friction of spring and inside and outside guard shield or damper external diameter, abnormal sound, piston rod and oil sealing eccentric wear, guard shield (spring, damper) a series of problems such as get rusty occur.In addition, the distance of switching political loyalty is generally all adopted in the design of the spring of motorcycle list spring vibration damper, and its spring performance line is the broken line that break is arranged, and also is prone to the buckling phenomenon of spring at the transition position of spring Mi Quan and thin circle.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned defective, a kind of reasonable in design is provided, when satisfying characteristic line behind the spring assembly and be broken line, avoided reaching Mi Quan greatly and dredging the upper, middle and lower three spring rear shock absorber of motorcycle of circle transition position bending deflection problem because of the ratio of height to diameter of spring.
For addressing the above problem, the technical solution adopted in the present invention is:
A kind of upper, middle and lower three spring rear shock absorber of motorcycle comprise shell, are provided with piston rod in the shell, and an end of piston rod is provided with installation sleeve, and the other end is provided with down installation sleeve, and described shell inner piston rod is provided with damper assembly and beam; One end of described shell is provided with regulator, it is characterized in that: the outer surface of described shell is provided with spring seat cushion, and spring seat cushion is provided with some springs, is provided with spring insert between the adjacent springs; Described spring insert is circular, be socketed on the shell, and spring insert is to be the dividing plate that the stainless steel material of 1-2cm is made by thickness.
Be disposed with upper spring, medi-spring and lower spring on the described spring seat cushion, be provided with the spring insert that thickness is 1.5cm between the adjacent springs.
The described installation sleeve of going up is provided with buffer ring and aluminium suspension ring.
Described installation sleeve down is provided with down buffer ring.
Described aluminium suspension ring inner side surface is provided with fastening screw nut.
The diameter of described upper spring, medi-spring, lower spring is 5-8cm.
The diameter of described upper spring, medi-spring, lower spring is 6cm.
The described installation sleeve of going up all is the installation sleeve of being made by ferrous material with following installation sleeve.
Owing to adopted technique scheme, compared with prior art, the present invention realizes stack by three springs of upper, middle and lower and two spring inserts, the Mean length of upper, middle and lower spring is 1/3 of original single spring, avoided single spring in compression process, because the slenderness ratio of spring reaches the bending deflection that Mi Quan dredges the circle transition position greatly, thereby cause some defectives of occurring.Three spring rates of upper, middle and lower can be designed to identical or different, pitch such as can be designed to or irregular pitch, can be designed to equal length or unequal length, it is isodiametric or anisodiametric to be designed to Spring Steel Wire.By different composite designs, can be designed to different spring performance lines such as linearity, broken line, approximate curve, also can be designed to different color combination, satisfy different user's requests.
The good stability of spring of the present invention, bending deformation quantity is little, that has avoided that phase mutual friction because of guard shield, damper and spring that spring bending causes causes gets rusty and damage and abnormal sound, simultaneously, the different colours of three springs of upper, middle and lower and spring insert, the combination back replaces the solid color of single spring, and color is more rich and varied, and the vibration damper outward appearance is more attractive in appearance.In addition, it is stronger that the fatigue ratio list of three springs of upper, middle and lower props up spring, and the life-span is longer.
The invention will be further described below in conjunction with the drawings and specific embodiments simultaneously.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the present invention.
Embodiment
Embodiment:
As described in Figure 1, a kind of upper, middle and lower three spring rear shock absorber of motorcycle comprise shell, be provided with piston rod in the shell, one end of piston rod is provided with installation sleeve 14, and the other end is provided with down installation sleeve 2, and described shell inner piston rod is provided with damper assembly 6 and beam 9.One end of described shell is provided with regulator 3.The outer surface of described shell is provided with spring seat cushion 4, and spring seat cushion 4 is provided with some springs, is provided with spring insert 8 between the adjacent springs.Described spring insert 8 is circular, be socketed on the shell, and spring insert 8 is to be the dividing plate that the stainless steel material of 1-2cm is made by thickness.
In the present embodiment, be disposed with upper spring 10, medi-spring 7 and lower spring 5 on the described spring seat cushion 4, be provided with the spring insert that thickness is 1.5cm between the adjacent springs.
In the present embodiment, the described installation sleeve 14 of going up is provided with buffer ring 13 and aluminium suspension ring 12.Described installation sleeve 2 down is provided with down buffer ring 1.In addition, aluminium suspension ring 12 inner side surfaces are provided with fastening screw nut 11.
