Description
Technical field
The invention belongs to amortisseur technical field, and more particularly, to one kind is applied to bicycle use rear shock absorber.
Background technology
In order that bicycle can keep comfortable experience of riding in the irregular location such as mountain region, avoid bicycle simultaneously
The infringement that body structure causes to structure when moving in out-of-flatness location, needs the appropriate location mounting shock absorber on bicycle,
The impulsive force that major part is ridden can be slowed down.
Being arranged on front fork existing bicycle damper more, under seat or on tripod, rear shock absorber is mounted to triangle
A kind of conventional damping device on frame.In existing rear shock absorber, outside telescopic arm with sleeve, it is provided with spring, thus realizing subtracting
The effect of shake shock-absorbing, but the ability that the rear shock absorber of this structure bears violent or unexpected vibrations is poor, is easily caused flexible
Between arm and sleeve, heavy wear even damages, and damping effect also has much room for improvement it is difficult to the need that are suitable on more precipitous section
Will.
Content of the invention
The invention is to solve the problems of the prior art, there is provided a kind of bicycle rear shock absorber, has good
Damping effect.
A kind of bicycle rear shock absorber that the invention provides, including the upper connecting portion being respectively arranged at two ends and lower company
Socket part, is fixedly connected with sleeve inside described upper connecting portion, is fixedly connected with telescopic arm inside described lower connecting portion, described flexible
Arm and described sleeve are coaxially and deeply to sleeve inner, and can carry out axial stretching motion with respect to described sleeve；Described
Upper connecting portion and lower connecting portion are respectively fixed with block plate and lower block plate, be fixed with and be surrounded between described upper block plate and lower block plate
Outside described sleeve and telescopic arm and the outer spring coaxial with the two；Described telescopic arm periphery is also evenly equipped with some flexible deformation
Arcuation shell fragment, described arcuation shell fragment one end is fixed on the end face of described sleeve, and the other end is fixed on described lower block plate.
Wherein, described arcuation shell fragment two ends are fixed with stator, and stator is provided with the through hole passing through for fastening bolt, institute
State and the fixing hole being mated with described fastening bolt is respectively equipped with sleeve and lower block plate outer surface, described arcuation shell fragment passes through described
Stator, fastening bolt and fixing hole are individually fixed in described sleeve and the outer surface of lower block plate.
Wherein, described arcuation shell fragment is preferably 3.

Specific embodiment
Below by combining accompanying drawing, the invention is further described.
A kind of embodiment of the invention structure as shown in Figure 1-2, including upper connecting portion 1 He being respectively arranged at two ends
Lower connecting portion 2, is fixedly connected with sleeve 3, is fixedly connected with telescopic arm inside described lower connecting portion 2 inside described upper connecting portion 1
4, described telescopic arm 4 is coaxial with described sleeve 3 and gos deep into sleeve 3, and can carry out axial with respect to described sleeve 3
Stretching motion；Described upper connecting portion 1 and lower connecting portion 2 are respectively fixed with block plate 5 and lower block plate 6, described upper block plate 5 and lower block
It is fixed with outside being surrounded on described sleeve 3 and telescopic arm 4 between disk 6 and the outer spring 7 coaxial with the two；Outside described telescopic arm 4
Also it is evenly equipped with some bending deformed arcuation shell fragments 8 week, described arcuation shell fragment 8 one end is fixed on the end face of described sleeve 3,
The other end is fixed on described lower block plate 6.Described arcuation shell fragment 8 in shock absorbing process, on the one hand can be bent and deformed and
Return action stores or releases energy, and cooperatively alleviates jerk power with outer spring 7；On the other hand, arcuation shell fragment 8 is fixing
Additionally it is possible to become buffer when sleeve 3 and telescopic arm 4 interaction between sleeve 3 and lower block plate 6, reduce abrasion, with
When additionally it is possible to correcting or offsetting issuable non axial active force between sleeve 3 and telescopic arm 4, reduce the two it further
Between non axial rigidity be lost.
Wherein, described arcuation shell fragment 8 (as shown in Figure 3-4) two ends are fixed with stator 81, and stator 81 is provided with for tight
It is respectively equipped with and consolidating that described fastening bolt 82 is mated on the through hole that fixing bolt 82 passes through, described sleeve 3 and lower block plate 6 outer surface
Determine hole (not shown), described arcuation shell fragment 8 is individually fixed in institute by described stator 81, fastening bolt 82 and fixing hole
State sleeve 3 and the outer surface of lower block plate 6.Described arcuation shell fragment 8 is preferably 3.
Wherein, it is provided with thread segment 11, the thread segment 11 of described upper block plate 5 and described connecting portion 1 in described upper connecting portion 1
