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 high-efficient bicycle amortisseur, has good
Damping effect.
A kind of high-efficient bicycle amortisseur that the invention provides, include being respectively arranged at the upper connecting portion at two ends with
Connecting portion, is fixedly connected with sleeve inside described upper connecting portion, is fixedly connected with telescopic arm inside described lower connecting portion, described stretches
Contracting arm and described sleeve are coaxially and deeply to sleeve inner, and can carry out axial stretching motion with respect to described sleeve；Institute
State connecting portion and lower connecting portion is respectively fixed with block plate and lower block plate, between described upper block plate and lower block plate, be fixed with cincture
Outside described sleeve and telescopic arm and the outer spring coaxial with the two；Described telescopic arm periphery is also evenly equipped with some linkage bullets
Spring, the two ends of described linkage spring are individually fixed on pin, positioned at described linkage both ends of the spring described pin respectively with institute
State sleeve and the outer surface integrally connected of lower block plate.
Wherein, described linkage spring is preferably 3.
Wherein, it is provided with thread segment in described upper connecting portion, described upper block plate is connected with the thread segment screw thread of described connecting portion
Connect.
Wherein, described upper block plate periphery is also uniformly fluted.
The invention structure is simple, be easy to processing, and damping effect is excellent, is particularly well-suited to the violent of extremely precipitous road surface
The demand of damping.The design of spring and pin that links is passed through in the invention, on the one hand can jointly alleviate vibrations with outer spring
Impulsive force, on the other hand can also slow down the abrasion between sleeve and telescopic arm, and corrects or offset non-between sleeve and telescopic arm
The rigidity loss that axial force causes.
Brief description
Fig. 1 is a kind of overall structure diagram of embodiment of the invention；
Fig. 2 is the partial structural diagram after removing outer spring in Fig. 1.
Wherein, the upper connecting portion of 1-；11- thread segment；Connecting portion under 2-；3- sleeve；4- telescopic arm；The upper block plate of 5-；51- is recessed
Groove；Block plate under 6-；7- outer spring；8- linkage spring；81- pin.
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 linkage springs 8 week, the two ends of described linkage spring 8 are individually fixed on pin 81, positioned at described linkage bullet
The described pin 81 at the spring 8 two ends outer surface integrally connected with described sleeve 3 and lower block plate 6 respectively.Described linkage spring 8 is subtracting
During shake, on the one hand by deformation and return action storage or can release energy, cooperatively alleviate vibrations with outer spring 7
Impulsive force；On the other hand, linkage spring 8 is fixed between sleeve 3 and lower block plate 6 additionally it is possible to become sleeve 3 and telescopic arm 4 phase
Buffer during interaction, reduces abrasion, simultaneously additionally it is possible to correcting or offsetting issuable between sleeve 3 and telescopic arm 4
Non axial active force, the non axial rigidity reducing further therebetween is lost.Described linkage spring 8 is preferably arranged to 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
Threaded, can suitably adjust the spacing between block plate 5 and lower block plate 6, so that outer spring 7 obtains suitable pretension and makees
With.
Wherein, described upper block plate 5 periphery also uniformly fluted 51, are easy to the clamping of instrument and to upper block plate 5 and connecting portion 1
Between relative position make adjustment.
The foregoing is only the preferred embodiment of the invention, not in order to limit the invention, all this
Within the spirit of innovation and creation and principle, any modification, equivalent substitution and improvement made etc., should be included in the invention
Protection domain within.
