Abstract
The utility model discloses a gear transmission accelerating bicycle, which comprises a chain wheel, a flywheel, a fixing bracket, pedals, and a bracket having support points positioned on the bottomof a cushion. One end of the bracket is connected to the chain wheel, while the other end is connected to the flywheel. An H-shape double-head concentric gear is disposed between the chain wheel and the flywheel, wherein the small gear is the accelerating crankset, and the large gear is the driving crankset. A bearing is disposed on the axis position of the double-head concentric gear. The fixingbracket is equipped with a fixing pore for passing through and fixing the bearing, having one end connected to the chain wheel, and the other end connected to the flywheel. The chain wheel is engagedwith the accelerating crankset, while the driving crandkset is engaged with the flywheel. Therefore, the chain wheel drives the H-shaped double head concentric gear, the accelerating crankset drives the driving crankset in use. The output linear speed is increased by the driving crankset, and the flywheel is driven by the driving crankset, so that gears are used for transmission and driving in order to achieve the object of acceleration.

The utility model content
At the problems referred to above, the utility model proposes a kind of simple in structurely, need not to use the gear transmission speeding-up bike of chain.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of gear transmission speeding-up bike, comprise that chain wheel, flywheel, fixed mount, pedal and intersection point are positioned at the support of cushion bottom, one end of described support connects chain wheel, the other end of described support connects flywheel, between chain wheel and flywheel, be provided with " worker " shape double end concentric gear, wherein the less end of basic circle is the speedup fluted disc, and the end that basic circle is bigger is the driving fluted disc; Place, described double end concentric gear axle center is provided with bearing; Offer on the described fixed mount for bearing and pass and fixing fixed orifice, an end of described fixed mount links to each other with chain wheel, and the other end of described fixed mount links to each other with flywheel; Described chain wheel and multiplying wheel engagement, described driving fluted disc and flywheel engagement.
Described gear transmission speeding-up bike, wherein said fixed orifice is opened in the middle part of fixed mount.
Described gear transmission speeding-up bike, the gear teeth of wherein said chain wheel or the flywheel all facewidth with the double end concentric gear are identical.
Described gear transmission speeding-up bike, the wherein said speedup fluted disc facewidth is identical with the driving fluted disc facewidth.
Described gear transmission speeding-up bike, wherein said transmission device outer setting has screened housing.
Described gear transmission speeding-up bike, wherein adopt the advantage of the present utility model of technique scheme to be:
The utility model drives " worker " shape double end concentric gear by chain wheel, drive the driving fluted disc by the speedup fluted disc, drive the fluted disc basic circle and want big than speedup fluted disc basic circle, thereby the linear velocity that drives fluted disc output is increased, flywheel is moved in the driving gear dribbling, drives the also purpose of speedup thereby reach by gear transmission.
