Abstract

The utility model discloses an auxiliary driving device which improves the existing driving mode of a bicycle. The existing pedals, the disk chuck, the chains and the free wheel of the bicycle are reserved; the improvement is that the disk chuck and a disk chuck free wheel added in the disk chuck are in the coaxial coupling with an inertia free wheel, the inertia free wheel is matched with a toothed rack, and the toothed rack is connected with the seat of the bicycle through a connecting rod provided with compensating springs. An original driving force used for feet treading to drive the disk chuck is reserved; at the same time, a driving force pushing the cycle to advance and transformed from the force of swing the body of a rider up and down is added to the utility model, and the mutual interference can not be generated between the driving forces which only play the reinforcing function; the utility model is an innovation product with the reasonable and scientific structure.

Description

Energy saving device of bicycle with three inertia sprockets

The utility model relates to a kind of driving device of wheeled car of rider driving, is meant especially to be applicable to the device that improves existing bicycle or tricycle kind system of vehicle transmission mode.

Existing bicycle or three-wheel vehicle all are to rely on rider to trample pedal, and powered vehicle is advanced, and also do not see the strength that can utilize rider health up-and-down movement and promote the accessory drive gear that vehicle advances.

The purpose of this utility model is to provide the accessory drive gear of a kind of bicycle or three-wheel vehicle, it relies on rider to trample the structure that the pedal powered vehicle advances except that possessing existing bicycle, also increase by a cover linkage, can utilize the strength of rider up-and-down movement to act on this accessory drive gear, strengthen the power that vehicle advances.

Embodiment of the present utility model is: the pedal, floral disc, chain and the flywheel that keep existing bicycle, its special character is, assembling one floral disc flywheel in floral disc, and with the coaxial inertial flywheel that is connected of floral disc, this inertial flywheel and tooth bar coupling, tooth bar is connected with vehicle seat by connecting rod, and balance spring is housed on the connecting rod.

The utility model has the advantages that: kept original all characteristics of bicycle, only increased once the simple auxiliary device of cover and can utilize the rider health moving strength of heavy curtain up and down, be transformed into the propulsive effort that the promotion bicycle advances.Be this class vehicle of bicycle or three-wheel vehicle, improve the innovative product of driving device.

Accompanying drawing 1 is the structure principle chart (double as Figure of abstract) of this inertia three flywheel labour saver for bicycle.

Accompanying drawing 2 is the floral disc part-structure schematic diagram of this inertia three flywheel labour saver for bicycle.

Accompanying drawing 3 is the front elevation of the floral disc of this inertia three flywheel labour saver for bicycle.

Drawing explanation: 1-vehicle seat, 2-balance spring, 3-connecting rod, 4-pedal, 5-tooth bar, 6-axis, 7-inertial flywheel, 8-floral disc, 9-chain, 10-flywheel, 11-floral disc flywheel.

Embodiment:

Accompanying drawing 1 is the structure principle chart of this inertia three flywheel labour saver for bicycle, 1 time a connecting rod 3 is installed at vehicle seat, one balance spring 2 is installed on connecting rod 3, tooth bar 5 is equipped with in the lower end of connecting rod 3, tooth bar 5 and inertial flywheel 7 couplings, this inertial flywheel 7 and floral disc 8 coaxial being installed on the axis 6, when the rider up-and-down movement, depress tooth bar 5 by vehicle seat 1 and drive inertial flywheel 7 rotations, because inertial flywheel 7 and floral disc 8 same axle mountings, thereby also drive floral disc 8 and rotate, and, bicycle is advanced, when the way up heavy curtain of rider is moving by 10 rotations of chain 9 drive flywheels, balance spring 2 resets vehicle seat 1, thereby the strength that heavy curtain about the rider health is moving has been transformed into driving bicycle power forward.Drive the strength of floral disc 8 and the strength that pedal 4 drives floral disc 8 in order to overcome inertial flywheel 7, the asynchronous inharmonious phenomenon that causes, assembling one floral disc flywheel 11 in floral disc 8, when pedal 4 drive floral disc flywheels 11 move clockwise, also drive simultaneously floral disc 8 and do the cw motion, when floral disc 8 is done the cw motion, because the effect of inertial flywheel 7 can't have influence on the motion of tooth bar 5.In like manner, when tooth bar 5 drives inertial flywheels 7 and clockwise rotates and drive floral disc 8 and clockwise rotate, also can not have influence on the motion of pedal 4 owing to the effect of floral disc flywheel 11.

Claims

1, a kind of inertia three flywheel labour saver for bicycle, comprise pedal, floral disc, chain and flywheel, it is characterized in that: assembling one floral disc flywheel in floral disc, and with the coaxial inertial flywheel that is connected of floral disc, this inertial flywheel and tooth bar coupling, tooth bar is connected with vehicle seat by connecting rod, and balance spring is housed on the connecting rod.
