Abstract
The invention discloses a motorcycle rear shock absorber provided with upper and lower springs. The rear shock absorber comprises a casing, wherein a piston rod is arranged in the casing; an upper installation sleeve is arranged at one end of the piston rod, and a lower installation sleeve is arranged at the other end of the piston rod; a damper component and a shock pad are arranged on the piston rod inside the casing; and a regulator is arranged at one end of the casing. The motorcycle rear shock absorber is characterized in that a spring positioning seat is arranged on the outer surface of the casing, the upper spring and the lower spring are arranged on the spring positioning seat, and a spring insert is arranged between the upper spring and the lower spring. The springs of the motorcycle rear shock absorber are good in stability and small in bending deformation, conditions of rusting, damage and abnormal sounds due to the fact that the springs are bent and a protecting cover, a damper and the springs are mutually rubbed are avoided; and simultaneously, the upper spring, the lower spring and the spring insert adopt different colors, the single color of a single spring is replaced after the upper spring, the lower spring and the spring insert are combined, and the color is richer, so that the appearance of the shock absorber looks more attractive.
Description
Technical field
The invention belongs to the vehicular shock absorber field, specifically, relate to a kind of two-man act rear shock absorber of motorcycle up and down.
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 rear shock absorber of motorcycle of two-man act up and down 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 two-man act rear shock absorber of motorcycle up and down comprises shell, is 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 the spring positioning seat, is provided with upper spring and lower spring in the spring positioning seat, is provided with spring insert between upper spring and the lower spring; Described spring insert is circular, be socketed on the shell, and spring insert is to be the dividing plate that the steel plate of 2-3cm is made by thickness.
Be provided with buffer ring and aluminium suspension ring between described piston rod and the last installation sleeve.
Be provided with down buffer ring between described piston rod and the following installation sleeve.
Be provided with spring seat cushion between described spring positioning seat and the outer surface of outer cover.
Described outer surface of outer cover is provided with protecting jacket.
Described aluminium suspension ring inner side surface is provided with fastening screw nut, and outer side surface is provided with decorative cover.
The diameter of described upper spring and lower spring is 5-8cm.
The diameter of described upper spring and 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 last lower spring and a spring insert, the Mean length of last lower spring is 1/2 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.Up and down spring rate 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 last lower spring and spring insert, the three makes up the solid color that the back replaces 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 last lower spring 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 two-man act rear shock absorber of motorcycle up and down, comprise shell, be provided with piston rod in the shell, one end of piston rod is provided with installation sleeve 14, the other end is provided with down installation sleeve 2, and described shell inner piston rod is provided with damper assembly 8 and beam 9, and an end of 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 upper spring 7 and lower spring 5, is provided with spring insert 6 between upper spring 7 and the lower spring 5.Described spring insert 6 is circular, be socketed on the shell, and spring insert 6 is to be the dividing plate that the steel plate of 2-3cm is made by thickness.
In the present embodiment, be provided with buffer ring 13 and aluminium suspension ring 12 between described piston rod and the last installation sleeve 14.Be provided with down buffer ring 1 between described piston rod and the following installation sleeve 2.
Outer surface of outer cover is provided with protecting jacket.Aluminium suspension ring 12 inner side surfaces are provided with fastening screw nut 10, and outer side surface is provided with decorative cover 11.
