Abstract
A transmission chain formed of alternating outer chain links (2) and inner chain links (3), connected by pins (4); the outer chain links (2) and the inner chain links (3) being formed of outer plates (21) and inner plates (31); each outer plate (21) and inner plate (31) having two widened ends each provided with a hole (25, 35) to accommodate the pin (4) and connected by a connection part (24, 34) characterized in that the connecting parts (24, 34) of the plates (21, 31) comprise apertures and the pins are hollow.
Description
The present invention is about drive chain, the chain on the bicycle.The outer chain of this chain is in the same place with the pin pin with interior chain, and outer chain and interior chain are made up of outer plate and inner plate respectively, and the two ends of outer plate and inner plate are widened and are provided with hinge last, are the attachment portions in the middle of the two ends.
Such chain is known.
Therefore, according to the known a kind of chain of file G9309645.3, its outer plate comprises a circular groove, and it enters the clutch that two gaps between the recess edge are guiding chain and runner tooth preferably by the tooth of gear.
The difficulty on using, the tooth of this chain and contacting of chain trough rim can produce sizable noise, and be the same with conventional chain relatively heavier.What is more, and the groove that forms link can stockpile dirt when not meshing, and chain rotated become difficult relatively, cleans more complicated.
The objective of the invention is to overcome above-mentioned shortcoming, a kind of in light weight and chain that intensity is high is produced in suggestion, prevents that dirt from stockpiling, and is easy to the removing of dirt and the circulation of oiling agent or cleaning solution.
In line with this purpose, invented the chain of the above-mentioned type.It is characterized in that on carrier bar perforate and and the pin of hollow.
Because perforate and the pin that adopts hollow on outer plate and inner plate, chain of the present invention is more light than the conventional chain with same intensity, and the advantage on this weight has satisfied the hope that people alleviate bicycle weight.Especially, because perforate on the attachment portion, dirt stockpiles to discontinuous, has reduced the dirt amount of stockpiling.As the attachment portion of carrier bar, its surface is all discontinuous on laterally vertical.
Simultaneously, this perforate has improved moving of oiling agent and clear agent again.
According to further embodiment of the present invention, the perforate on the carrier bar is long, and the two ends in hole are circular.Mechanically the inaction parts are corresponding for the structure of these perforates and each carrier bar.
Another kind of better method is that the dowel ends in hollow comprises groove, makes the end open slightly, and pin is stuck on two outer plates.
By means of accompanying drawing, can illustrate in greater detail the present invention.
Fig. 1 is a chain planimetric map of the present invention
Fig. 2 is the profile of Fig. 1 chain
Fig. 3 is an III-III sectional drawing among Fig. 1 of amplifying of ratio
Fig. 4 is an IV-IV sectional drawing among Fig. 1 of amplifying of ratio
Fig. 5 is a V-V sectional drawing among Fig. 1 of amplifying of ratio
Fig. 6 is an outer plate of the present invention, and VI is to view among the figure I.
Fig. 7 be among inner plate Fig. 1 of the present invention VII to view.
As shown in Figure 1 and Figure 2, the present invention is about drive chain, especially the drive chain of bicycle use.The identification number of whole chain is 1, and it is made of outer chain 2 and interior chain 3, and outer chain and interior chain alternately are formed by connecting its end by pin 4.
Two outer plates 21 are formed 2, two inner plates of outer chain 31 and are formed interior chain 3.
Outer plate as shown in Figure 6, inner plate is as shown in Figure 7.
As shown in Figure 7, the structure of inner plate 31 is adopted and is used the same method, and two wide ends 33 of plate 31 are provided with sleeve 32, and the inner ring of sleeve 32 forms pin patchhole 35.This inner plate is provided with same perforate 36.
Perforate 26,36th, slotted hole, its two ends are done circular, and width is wideer than intermediate portion, and the shape of its shape and carrier bar is identical basically.
The assembling of inside and outside chain and latch can be seen clearlyer from Fig. 3, and pin 4 is stuck on the outer plate 21, and this pin is supporting the inner plate 31 with sleeve 32.At last, sleeve 32 support rollers 5.
As Fig. 3 and Fig. 4, shown in Figure 5, the groove 42 that pin two ends 41 are provided with helps pin is stuck among outer plate 21 pin holes 25.
Fig. 4, Fig. 5 illustrate in greater detail outer plate section (Fig. 4) and the inner plate section of looking from perforate 26,36 right sides (Fig. 5) respectively.
These sectional drawings have also been represented distinctive carrier bar shape, and its very thin part more helps the contact and the clutch of runner tooth.
The present invention not only is confined to the foregoing description.Especially outer chain or inner plate can comprise the attachment portion of big width.
The present invention not only is used for the drive chain of bicycle, also can be used on motor vehicle, on the wheel chain of moped and industrial machinery.
Claims (2)
1. the chain of using on a drive chain, the especially bicycle:
Outer chain (2) and interior chain (3) alternately is formed by connecting by pin 4,
Outer chain (2) and interior chain (3) comprise outside plate (21) and inner panel (31),
Each outside plate (21) and inner panel (31) two wide ends (23,33) are respectively equipped with hole (25,35) to insert pin (4), are connected by link (24,34).
It is characterized in that:
Comprise that on the attachment portion (24,34) of plate (21,31) its perforate end of perforate (26,36) is circular, and pin (4) is to adopt hollow.
2. by the chain of claim 1, its feature is that also the pin of hollow (4) end (41) is provided with the groove (42) that is used to tighten usefulness.
