Abstract
The utility model discloses the actuating device of a chainless bicycle, comprising a drive gear, a transmission shaft, a driven gear, a transition speed transforming gear and two transmission gears. The transition speed transforming gear are engaged with the drive gear and the first transmission gear respectively, the two transmission gears are fixed on the cross-sections of the two ends of the transmission shaft, the driven gear is engaged with the second transmission gear and connected with the rear wheel of the bicycle, the centre shaft of the drive gear is connected with the drive gear as a whole, and the centre shaft is connected with the foot board of the bicycle. The actuating device of a chainless bicycle of the utility model which is more safe avoids the phenomenon that the fittings get loose during the process of using the bicycle, improves the transmission efficiency, improves the running speed obviously, and reduces the power loss of the rider.
Description
[technical field]
The utility model relates to a kind of driving device of bicycle, relates in particular to a kind of driving device of chain-less bicycle.
[background technology]
The driving device of traditional bicycle is to adopt chain transmission mode, and its driving efficiency is low, can bring phenomenons such as taking off chain, chain rupture, greasy dirt, clip divided skirt during the therefore slow and effort of the speed of riding, and chain gear, therefore makes troubles to the rider.Just begin the someone for this reason and study chain-less bicycle, China Patent No. is that 98237939.0 patent documentation discloses a kind of no sprocket gear driving bicycle actuating device, it is by axis, crank, the bevel gear group, transmission shaft, bearing, rear axle, compositions such as backshaft skin, with a gear case with axis, the bevel gear group encapsulates, preceding driving wheel is sleeved on an end of axis, be connected with the front driven wheel engagement, the transmission shaft two ends are connected with rear drive gear with preceding driven gear respectively, drive ratchet by the back driven gear again, the ratchet overcoat, backshaft skin rotates, thereby drives wheel revolutions.But above-mentioned no sprocket gear driving bicycle driving device structure complexity, and its driving efficiency is not high.
[summary of the invention]
For the shortcoming that the driving device that overcomes traditional bicycle adopts chain transmission mode to produce, the utility model provides a kind of driving device that adopts the chain-less bicycle of direct geared.
For realizing the purpose of this utility model, the technical scheme that the utility model adopted is: a kind of chain-less bicycle driving device is provided, it comprises driving gear, transmission shaft and ring gear, it is characterized in that: it also comprises transition variable gear and two transmission gears, this transition variable gear is meshed with the driving gear and first transmission gear respectively, this two transmission gear is separately fixed on the cross-sectional plane at two ends of transmission shaft, this ring gear is meshed with second transmission gear, and be connected with the trailing wheel of bicycle, the axis of this driving gear and this driving gear are connected as a single entity, and this axis is connected with stretcher.
The beneficial effects of the utility model are: because the driving device of chain-less bicycle of the present utility model adopts the through-coupling that cooperatively interacts of gear, thereby make bicycle in the process of using, the phenomenon that accessory gets loose can not occur, and improved driving efficiency, reduce the person's of riding strength loss, also safer; In addition, because driving device of the present utility model has increased the transition variable gear, thereby the moving velocity of bicycle is significantly improved.
[description of drawings]
Fig. 1 is the scheme drawing of the utility model chain-less bicycle driving device.
[specific embodiment]
See also Fig. 1, chain-less bicycle driving device of the present utility model comprises plane driving gear 1, plane transition variable gear 2, chamfered transition variable gear 3, inclined- plane transmission gear 4 and 5 and inclined-plane ring gear 6.Wherein, plane transition variable gear 2 is meshed at same horizontal surface with plane driving gear 1; Chamfered transition variable gear 3 is connected as a single entity with plane transition variable gear 2, and its inclined-plane is towards body side, and promptly the low spot of the tooth of gear 3 is in body side, and its oblique angle is 45 degree, this chamfered transition variable gear 3 and inclined-plane transmission gear 4 mutual Vertical Meshing; Transmission gear 4 usefulness Luo silks in inclined-plane are fixed on the cross-sectional plane of transmission shaft 9 one ends, and its inclined-plane is towards the center of gear, and promptly the low spot of tooth is at the central side of gear, and its oblique angle is 45 degree, and gear by body side and chamfered transition variable gear 3 mutual Vertical Meshing; Transmission gear 5 usefulness Luo silks in inclined-plane are fixed on the cross-sectional plane of transmission shaft 9 other ends, and the inclined-plane is towards the center of gear, and promptly the low spot of tooth is at the central side of gear, and its oblique angle is 45 degree; Inclined-plane ring gear 6 can drive the trailing wheel running of bicycle, and its inclined-plane is towards the vehicle body outside, and the oblique angle is 45 degree, and with inclined-plane transmission gear 5 by the mutual Vertical Meshing of body side; The synchronized operation that is connected as a single entity of the axis 7 of plane driving gear 1 and gear 1, this axis 7 is connected with stretcher; The fixedly steel axle 8 of plane transition variable gear 2 and chamfered transition variable gear 3 is fixed together by bearing and gear 2 and 3, and fixedly an end of steel axle 8 is fixed on the vehicle frame; Transmission shaft 9 is used to connect inclined- plane transmission gear 4 and 5, and it is fixed on the vehicle frame by support by two bearings 10.
The working process of chain-less bicycle driving device of the present utility model is: the strength of pedal passes on the axis 7 by the stretcher that is connected on the axis 7, drive plane transition variable gear 2 rotations that are meshed with it by the plane driving gear 1 that is connected as a single entity with axis 7 then, from and the chamfered transition variable gear 3 that is connected as a single entity of drive and plane transition variable gear 2 rotate, chamfered transition variable gear 3 drives with its ingear inclined-plane transmission gear 4 again and rotates, inclined-plane transmission gear 4 drives inclined-plane transmission gear 5 by transmission shaft 9 and rotates, inclined-plane transmission gear 5 drives with its ingear inclined-plane ring gear 6 and rotates then, drive the trailing wheel running of bicycle at last by inclined-plane ring gear 6, thereby drive the motion of whole bicycle.
