Abstract
The invention relates to a transmission shaft bicycle speed-changing power device, which belongs to the technical field. The invention aims at providing a transmission shaft speed-changing power device for a bicycle. The technical scheme is as follows: a middle shaft is driven by a pedal to rotate, the middle shaft drives a front conical toothed disc 1 which is fixedly connected with the middle shaft to rotate, so that a conical gear 9 can shift a front gear 3 so as to drive a transmission shaft 5 and a rear gear 11 to rotate, a rear gear 11 can shift a conical gear 14 to rotate, so that a conical toothed disc 6 drives a flywheel to rotate and a rear wheel of the bicycle to rotate, and the bicycle can run forwards. The front gear 3 and the rear gear 11 are shifted to slide on a transmission shaft key 8 and a transmission shaft key 15 in the axial direction to be engaged with conical gears 9 and 14 on different gears of the conical toothed discs 1 and 6, so that six different speeds can be formed. By increasing the turns of the conical gears 9 and 14, the transformation of multiple speeds can be realized. The device is firm and durable, low in cost, easy to popularize and capable of becoming a main power device for the bicycle in the future.
Description
Technical field
The invention belongs to technical field of bicycles, is a kind of shaft driven bicycle speed changing power mechanism.
Background technology
Existing bicycle transmission structure is mainly chain gear, and the major defect of this structure is that chain in use easily elongates, disconnected button, and easily fall chain, spooling clothing make troubles to bicyclist, are difficult to meet people's demand.
Summary of the invention
The object of the invention is to overcome the above-mentioned defect of existing bicycle transmission structure, a kind of shaft driven bicycle speed changing power mechanism is provided.
This invention technical scheme is as follows:
This speed changing power mechanism, comprises front taper teeth dish, front gear, front gear dop, front gear cutting ferrule, rear conical insert chain wheel, backgear, backgear dop, backgear cutting ferrule and transmission shaft and forward and backward bearing.These transmission shaft two ends are uniformly distributed respectively four keys (as shown in Figure 4,5), and forward and backward gear can slide axially on the key at transmission shaft two ends, and can drive transmission shaft to rotate.Forward and backward conical insert chain wheel is the disk of middle part dimpling, is uniformly distributed conical tooth (as shown in Figure 6,7) above.In this speed changing power mechanism, bicycle middle shaft passes front taper teeth disk center and fixes with this chain wheel, flywheel on rear conical insert chain wheel and bicycle rear axle is fixed, before, backgear is enclosed within transmission shaft two ends, transmission shaft two ends put into be fixed on cycle frame before, in rear bearing, pedal drives axis to rotate, before axis drives, taper teeth dish rotates, conical tooth on front taper teeth dish is stirred front gear and is rotated, front gear drives transmission shaft to rotate, transmission shaft rotates and drives backgear to rotate, backgear is stirred rear conical insert chain wheel and is rotated, rear conical insert chain wheel flywheel driven rotates, flywheel rotates and drives bicycle rear to rotate, thereby make bicycle to overtake.
On front taper teeth dish, have the conical teeth of three circles, represent 3 speed thresholds, by great circle to ringlet Speed Reduction; On rear conical insert chain wheel, there is the conical tooth of two circles, represent 2 speed thresholds, raise to ringlet speed by great circle.Stir forward and backward gear on the key of transmission shaft, slide axially respectively with each speed threshold on conical tooth interlock can realize the speed transformation of 3*2=6 kind, in the time that the conical gear ring on the forward and backward conical insert chain wheel of increase is counted, can realize more multiple speed shelves conversion, both can strengthen grade climbing performance, save muscle power by low speed driving, can run at high speed and save time again, raise the efficiency, can meet people's different requirements.
