Abstract
The utility model discloses a gear change automatic vehicle, which changes the chain wheel speed changing of the normal speed changing bicycle into the gear wheel speed changing, and the shaft driving is realized. The utility model has the advantages of flexible speed changing, long speed changing mechanism service life, and that the production, installation and application are simple, the generalization and the standardization of the components are easy to be realized, and the utility model is suitable for ride instead of walk, exercise and amusement.
Description
The utility model relates to a kind of variable speed bicycle that has speed-change gear.
The speed change majority of existing variable speed bicycle is by being realized by the mode of dialling the transmission on the chain wheel of different sizes and different big or small flywheel of chain device control chain, this gear shift mode transforming gear clumsiness, the life-span of speed-changing mechanism is short, and the requirement of making, installing and using is all higher, also is difficult to realize simultaneously shaft drive.
The purpose of this utility model be to overcome above-mentioned weak point of the prior art and provide a kind of and be suitable for riding instead of walk, the bicycle with toothed wheel of changeable transmission ratio of body-building, amusement.
The purpose of this utility model can reach by following structure, change speed gear box by the tertiary gear transmission of plugging in retaining fork may command cliding gear gear promptly is installed on vehicle frame, the input shaft of change speed gear box is the pedal crank shaft, and the chain wheel of a chain drive-belt or the bevel gear of driving transmission shaft are installed on the output shaft.
The drawing of accompanying drawing is described as follows:
Fig. 1 is change speed gear box drive mechanism figure of the present utility model,
Fig. 2 is a shaft drive constructional drawing of the present utility model,
Fig. 3 is a plug in retaining system construction drawing of the present utility model,
Fig. 4 is a gear change system constructional drawing of the present utility model,
Fig. 5 is an overall diagram of the present utility model,
Fig. 5 is a Figure of abstract.
The utility model is described in further detail below in conjunction with the accompanying drawing illustrated embodiment.
The utility model is by front and back wheel (1), (9), antero posterior axis (17), (11), front fork (2), handlebar (3), vehicle frame (5), saddle (8) is formed, one speed-changing gear box (7) is housed on vehicle frame (5), rotation engage a gear handgrip (4) on the handlebar (3) is inserted the action that retaining is pitched (18) by steel wire (6) control, makes cliding gear (19) go up gear (21) (22) (23) engagement and driven gear (24) rotation that layout is installed with tween drive shaft (20) respectively.Input shaft (15) is pedal crank shaft (15), a chain wheel (26) or bevel gear (27) can be installed on the output shaft (25) drive trailing wheel (9) rotation by chain (13) or transmission shaft (28).Engagement respectively by the gear (21) (22) (23) on cliding gear (19) and the tween drive shaft (20) can realize speed ratio 1:1 to 1:7.
The utility model compared with prior art, changing speed variable chain wheel into gear graduation, to have a speed change engage a gear flexible, the gear life-span is long, making, installation, easy to use, member is easily realized standardization and generalization, is suitable for riding instead of walk, the advantage such as body-building, amusement.
Claims (2)
1, a kind of variable speed bicycle of forming by front and back wheel, antero posterior axis, front fork, handlebar, vehicle frame, saddle, it is characterized in that its speed-changing mechanism be one by inserting the speed-changing gear box that the retaining fork can its gear of conversion, the input shaft of change speed gear box is the pedal crank shaft, adorn on the output shaft one can be by the chain drive trailing wheel chain wheel or drive the bevel gear of trailing wheel by transmission shaft.
2, variable speed bicycle according to claim 1 is characterized in that described speed-changing gear box is a tertiary gear transmission device, and installing one on input shaft can be by the cliding gear with the gear in footpath in three kinds of differences of inserting its gear of retaining fork control; On the tween drive shaft successively layout install three can be respectively and the cliding gear gears in mesh; Install on the output shaft one with tween drive shaft on the gear of a gear mesh, and outside casing chain wheel of installation.
