Abstract
The utility model discloses a front wheel driving device for a bicycle, comprising a manual bracket, a centre shaft, a centre bearing, a main chain wheel, a crank, a chain and the tension component of the chain. The driving device can be fixed directly on the handle bar of the bicycle by using an anchor ear and screws, and can dispense with any big changes for the original bicycle and has simple assembly; the lengthening connecting rod of pedal cranks can be added, the output power rate of the whole bicycle can be increased when the user rides, and the speed of the bicycle can be improved 50 %. The utility model is suitable for traveling, body building, grade climbing and crossing country and is suitable to the application of loading with the front wheel drive of a manpower tricycle, and the bicycle rider with a bit training can expertly control.
Description
The utility model relates to a kind of bicycle auxiliary device--front-wheel drive.
The people is by bike the time, and armrest rotates the crank of this device, and large toothed disk is rotated, and is attached thereto the front-wheel that connects with chain and rotates to reach, and during rotating crank, can also play the turning of bicycle effect.
When by bike, general not work done of hand only plays the grasp handlebar, firmly scrunches sometimes, also is subjected to very big pressure usually on handlebar, and this power is the energy that slatterns in riding.At ordinary times by bike, the power of arm also can't be brought into play.In order to utilize the energy of arm, in prior art, use crankshaft system, or, make chain drive the flywheel that is fixed on the front-wheel by connecting rod swing, front-wheel is rotated.For example: U.S. Pat P4147370 is to utilize handlebar to make front-rear reciprocation movement, by connecting rod crank motion is become to rotatablely move, and drives flywheel front-wheel is rotated.The shortcoming that this patent exists be the pivot system in order to cross the dead point, increased displacement component, this is necessary, but the shortcoming of also having brought friction to strengthen, and connecting rod is too many, complex structure.See that from its accompanying drawing the little trailing wheel of front-wheel is big, this has just brought the nonsynchronous problem of front and back wheel.Pin is made circular movement, and hand is reciprocating, and trick is difficult for coordinating when riding.Because the gravity relation, strength was less when hand pushed away forward, and pulling force is bigger during toward post-tensioning, and gave the various shortcoming such as having brought inconvenience of getting on the bus because of handlebar is movable.
Task of the present utility model is the bicycle front-wheel drive device that does not have above-mentioned shortcoming about making.
Figure one is that the bicycle that front-wheel drive is housed is always schemed.
Figure two is bicycle front-wheel drive device figure.
Design feature of the present utility model is that manual support (2) is screwed on handlebar (1) with four anchor ears (3), axis, middle (center) bearing, large toothed disk, crank, small bell is housed in manual support (2) rear end (near body part), reaches chain guard. Manually support (2) front end is equipped with automatic chain tensioning mechanism, and it is made up of two little guide wheels (4) tensioning springs (5) and mistake wheel support (6). Set screw can prevent chain jumping tooth with regard to the capable of regulating spring. Change the front fork (7) of widening, more common front-wheel is changed the trailing wheel that can fill flywheel, load onto then chain (8), shake the whole device of crank, can run well.
This apparatus structure is simple, and most of part in addition such as large toothed disk, axis, centre bearer, crank etc. all adopt bicycle standard part in addition.Bicycle itself need not done any change yet, add up, thereby repacking is simply with low cost.Brothers unite when driving, and because of the front and back wheel size is the same, manually the large toothed disk on the support (2) is identical with the foot-operated crank large toothed disk number of teeth, can reach synchronously and brothers' coordination.Because the function of hand is different from foot, so when hand front-wheel drive, do not have the problem of lower dead point.Singlehanded moving when riding, both hands moving or brothers unite and drive two-wheel and all can.Trailing wheel also is equipped with backpedalling brake except that stopping brake lock, so braking is reliable, and driving safety.
The utility model device is being ridden on the crank in addition through test of many times, has increased to add long connecting rod, and whole bicycle horsepower output increases when riding, and can improve the speed of a motor vehicle 50%.Thereby bicycle of the present utility model is housed, possess Regular Bicycle multifunctional usage can't be obtained.Be applicable to that traffic is ridden instead of walk, the usefulness of tourism, body-building, cross-country, climbing and recreation, also can be used as the usefulness of bogie.All need trick associating device driven also can be widely used in manpower cargo transport three-wheel vehicle, body-building vehicle and other.Thereby this device improved the bicycle performance, satisfies the many-sided requirement of broad masses, thereby bicycle is further developed.
