Description

A kind of bicycle use shell fragment buffer
Technical field
The invention belongs to damper technical field, 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 location of the out-of-flatnesses such as mountain region, while avoid bicycle Body structure damages the appropriate location mounting shock absorber, it is necessary on bicycle when out-of-flatness location is moved to caused by structure, The impulsive force largely ridden can be slowed down.
Existing bicycle damper is arranged under front fork, seat or on tripod more, and rear shock absorber is mounted to triangle A kind of conventional damping device on frame.In existing rear shock absorber, spring is provided with outside telescopic arm and sleeve, is subtracted so as to realize Shake shock-absorbing effect, but the rear shock absorber of this structure bear violent or unexpected vibrations ability it is poor, easily cause to stretch Heavy wear even damages between arm and sleeve, and damping effect also has much room for improvement, it is difficult to the need being applicable on more precipitous section Will.
The content of the invention
The invention is solution the problems of the prior art, there is provided a kind of bicycle use shell fragment buffer, tool There is good damping effect.
A kind of bicycle use shell fragment buffer that the invention provides, including it is respectively arranged at the upper connection at both ends Portion and lower connecting portion, the upper connecting portion inner side are fixedly connected with sleeve, telescopic arm are fixedly connected with the inside of the lower connecting portion, The telescopic arm is coaxial with the sleeve and deeply to sleeve inner, and the flexible fortune of axial direction can be carried out relative to the sleeve It is dynamic;The upper connecting portion and lower connecting portion are respectively fixed with block plate and lower block plate, fixed between the upper block plate and lower block plate Have and be surrounded on outside the sleeve and telescopic arm and the outer spring coaxial with the two;The telescopic arm periphery be also evenly equipped with it is some can The arcuation shell fragment of flexural deformation, described arcuation shell fragment one end are fixed on the end face of the sleeve, the other end be fixed on it is described under On block plate.
Wherein, the arcuation shell fragment both ends are fixed with stator, and stator is provided with the through hole passed through for fastening bolt, institute State and the fixing hole matched with the fastening bolt is respectively equipped with sleeve and lower block plate outer surface, the arcuation shell fragment passes through described Stator, fastening bolt and fixing hole are individually fixed in the outer surface of the sleeve and lower block plate.
Wherein, the arcuation shell fragment is preferably 3.
Wherein, thread segment is provided with the upper connecting portion, the thread segment screw thread of the upper block plate and the connecting portion connects Connect.
Wherein, the upper block plate periphery is also uniform fluted.
The invention is simple in construction, is easy to process, and damping effect is excellent, especially suitable for the violent of extremely precipitous road surface The demand of damping.On the one hand the invention can alleviate jerk power jointly by the design of arcuation shell fragment with outer spring, On the other hand the abrasion between sleeve and telescopic arm can also be slowed down, and correct or offset non axial effect between sleeve and telescopic arm Rigidly it is lost caused by power.
Brief description of the drawings
Fig. 1 is a kind of overall structure diagram of embodiment of the invention;
Fig. 2 is that the partial structural diagram after outer spring is removed in Fig. 1;
Fig. 3 is the structural representation of arcuation shell fragment;
Fig. 4 is structural representation of the arcuation shell fragment in another direction of observation.
Wherein, the upper connecting portions of 1-;11- thread segments;Connecting portion under 2-;3- sleeves;4- telescopic arms;The upper block plates of 5-;51- is recessed Groove;Block plate under 6-;7- outer springs;8- arcuation shell fragments;81- stators;82- fastening bolts.
Embodiment
The invention is further described below by with reference to accompanying drawing.
A kind of embodiment of the invention structure as shown in Figure 1-2, including is respectively arranged at the He of upper connecting portion 1 at both ends Lower connecting portion 2, the upper inner side of connecting portion 1 are fixedly connected with sleeve 3, and the lower inner side of connecting portion 2 is fixedly connected with telescopic arm 4, the telescopic arm 4 is coaxial with the sleeve 3 and gos deep into sleeve 3, and can be carried out relative to the sleeve 3 axial Stretching motion;The upper connecting portion 1 and lower connecting portion 2 are respectively fixed with block plate 5 and lower block plate 6, the upper block plate 5 and lower block It is fixed with and is surrounded on outside the sleeve 3 and telescopic arm 4 and the outer spring 7 coaxial with the two between disk 6;Outside the telescopic arm 4 Week is also evenly equipped with some bending deformed arcuation shell fragments 8, and described one end of arcuation shell fragment 8 is fixed on the end face of the sleeve 3, The other end is fixed on the lower block plate 6.The arcuation shell fragment 8 in shock absorbing process, on the one hand can be bent and deformed and Return action stores or released energy, and cooperatively alleviates jerk power with outer spring 7;On the other hand, arcuation shell fragment 8 is fixed Between sleeve 3 and lower block plate 6, additionally it is possible to buffer when being interacted as sleeve 3 and telescopic arm 4, reduce abrasion, together When, additionally it is possible to issuable non axial active force between sleeve 3 and telescopic arm 4 is offset in correction, further reduces the two it Between it is non axial rigidity loss.
Wherein, arcuation shell fragment 8 (as shown in Figure 3-4) both ends are fixed with stator 81, and stator 81 is provided with for tight It is respectively equipped with the through hole that fixing bolt 82 passes through, the sleeve 3 and the lower outer surface of block plate 6 and consolidates with what the fastening bolt 82 matched Determine hole (not shown), the arcuation shell fragment 8 is individually fixed in institute by the stator 81, fastening bolt 82 and fixing hole State the outer surface of sleeve 3 and lower block plate 6.The arcuation shell fragment 8 is preferably 3.
Wherein, thread segment 11, the thread segment 11 of the upper block plate 5 and the connecting portion 1 are provided with the upper connecting portion 1 Threaded connection, can suitably adjust the spacing between block plate 5 and lower block plate 6, so that outer spring 7 obtains appropriate pretension and made With.
Wherein, the periphery of upper block plate 5 also uniform 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 preferred embodiment of the invention is the foregoing is only, is not intended to limit the invention creation, it is all at this Within the spirit and principle of innovation and creation, any modification, equivalent substitution and improvements made etc., the invention should be included in Protection domain within.
