The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
Variable gear of the present invention comprises at least four gear pieces, described gear piece is superimposed, each gear piece comprises gear ring and is distributed in the tooth in gear ring periphery, tooth on described gear piece according to chain from adjacent gear piece excessively to this gear piece the order of tooth of process be set as the first gear teeth and other gear teeth, wherein, the height of the first gear teeth on adjacent several gear pieces is lower than the height of other gear teeth on this gear piece.The present invention reduces the height of the first gear teeth on several adjacent gear pieces, thereby be convenient to chain, between gear piece, switches, and has avoided producing and rubbing between chain and gear piece.This structure decrease and chain friction, the noise having produced while having reduced speed change, upper and lower chain is more smooth and easy, rides more comfortable.
As illustrated in fig. 1 and 2, structural representation for a kind of embodiment of the present invention, this variable gear comprises eight gear pieces, the first gear piece 2, the second gear piece 3, the 3rd gear piece 4, the 4th gear piece 5, the 5th gear piece 6, the 6th gear piece 7, the 7th gear piece 8 and octadentate sheet 9 are arranged side by side, the quantity of its tooth increases successively, on eight gear pieces, have hole, be provided with draw-in groove in hole, eight gear pieces are connected on the flower-drum on bicycle by draw-in groove respectively.Eight gear pieces of the present invention are used for realizing the speed change of bicycle, and the diameter of eight gear pieces also increases successively, the various profiles of tooth on gear piece, and upper and lower chain better faster while being mainly speed change, the switching by chain on eight gear pieces, to realize bicycle shift.Between described the 3rd gear piece 4, the 4th gear piece 5, the 5th gear piece 6, the 6th gear piece 7, the 7th gear piece 8 and octadentate sheet 9, by rivet 10, connect, thereby six more gear pieces of the number of teeth are fixed together.
Of the present invention and emit 1 for gear piece is fixedly connected with the flower-drum on bicycle, described and emit 1 two ends to be provided with screw thread, the flower-drum on one end and bicycle is connected, and the other end and the first gear piece 2 are connected, for the ease of dismounting, and emit and in 1 endoporus, also have 12 well-distributed grooves.Described the 3rd gear piece 4, the 4th gear piece 5, the 5th gear piece 6, the 6th gear piece 7, the 7th gear piece 8 and octadentate sheet 9 are provided with 11, six gear pieces that are fixed together of cushion rubber and separate by cushion rubber 11, avoid friction.
The gear piece of 13 teeth on variable gear of the present invention, the gear piece of 15 teeth, the gear piece of 18 teeth, the height of the first gear teeth on the gear piece of the gear piece of 21 teeth and 24 teeth are lower than the height of other gear teeth on this gear piece, form the first gear teeth region 12, there is shown three gear teeth regions, to on gear, set three the first gear teeth, thereby formed three the first gear teeth regions.The height of the first gear teeth of the present invention slightly exceeds the periphery of gear ring, the first gear teeth and gear ring between diff-H be less than a threshold value, the scope of this threshold value is set as required, can be for example on this gear piece other gear teeth height 1/10～1/3.More preferably, this first gear teeth is removed completely, equal with the periphery of gear ring, forms hypodontia structure.This first gear teeth also can be designed to stream line pattern, be convenient to chain from adjacent gear piece excessively to this gear piece.This hypodontia structure can not be used on 11 teeth, 28 teeth, 32 teeth.Because the power that 11 teeth are subject to when riding is maximum, hypodontia can cause 11 tooth insufficient strength.Very large as for 28 teeth, the 32 teeth angle that chain is oblique in the maximum sheet of front chain wheel, use hypodontia structure chain when reversing not lead and just can cause chain sling, so 28 teeth, 32 teeth can not be used hypodontia structure.
Tooth on gear piece of the present invention is divided into several regions, and each region is provided with the first gear teeth and other gear teeth.More preferably, this gear piece is provided with three the first gear teeth.Gear piece is uniformly distributed to three tooth regions, and each region is provided with first gear teeth.
As shown in Figures 3 and 4, the structural representation of the 5th gear piece of a kind of embodiment of the present invention, tooth on the 5th gear piece is divided into three regions, there is the first gear teeth 51 in each region, it is the gear piece that chain is encountered at first when the 4th gear piece carries out speed change to the five gear piece, also be referred to as speed change and order gear piece, after the first speed change gear piece, be provided with successively the second gear teeth 52, the 3rd gear teeth 53, the 4th gear teeth 54, the 5th gear teeth 55, the 6th gear teeth 56.When chain accelerates to the 5th gear piece from the 4th gear piece, this chain during through lower the first gear teeth in position, can not produce larger friction, thereby realize without friction variable speed, has reduced noise.
The present invention also provides a kind of bicycle, comprise variable gear and chain, described variable gear comprises at least four gear pieces, described gear piece is superimposed, each gear piece comprises gear ring and is distributed in the tooth in gear ring periphery, described chain slides between different gear pieces, tooth on described gear piece according to described chain from adjacent gear piece excessively to this gear piece the order of tooth of process be set as the first gear teeth and other gear teeth, wherein, the height of the first gear teeth on adjacent several gear pieces is lower than the height of other gear teeth on this gear piece.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and replacement, these improvement and replacement also should be considered as protection scope of the present invention.
