Abstract
The utility model relates to an automatic speed changing bicycle which can be driven by inverse pedaling and is a novel bicycle. The utility model is characterized in that a drive mechanism is composed of a driving sprocket, two fly wheels, a transition wheel and a chain. The bicycle can be driven to go forward regardless of positive or inverse pedaling. In addition, the bicycle has the functions of automatic speed changing and uphill retreat stopping. The ride is comfortable, safe and effective. The utility model is an upgrading and replacing product for the existing bicycles and is particularly suitable for cross-country bicycles and racing bicycles.
Description
The utility model is the bicycle that has improved.
Existing bicycle can only be pedaled forward and could drive, and variable speed bicycle carries out speed change by dialling the chain device.
The purpose of this utility model: increase the back-pedal driver train, realize automatic speed changing.
The utility model is the flywheel of two different numbers of teeth of coaxial installation on the bicycle rear axle skin, and drive sprocket drives one of them flywheel on the backshaft skin respectively by chain, makes transmission form circulation by transition wheel.In order to move backward, one of them flywheel is connected with power-transfer clutch with backshaft skin.
Existing bicycle type of drive dullness, the speed-changing mechanism complexity is ridden for a long time, and is tired easily.The utility model has been set up the back-pedal actuating device, and the user can select the direction of pedal arbitrarily according to physical condition and road conditions, or indefatigability is carried out in two way alternate.Simultaneously can also realize automatic speed changing,, can obtain different speed ratios, bring convenience safety to use as long as change the direction of pedal.
Accompanying drawing is a scheme drawing of the present utility model.
With reference to the accompanying drawings utility model is described in further detail.
[1] is that drive sprocket, [2] [3] are backshaft skin for transition wheel, [5] for chain, [6] for flywheel, [4] among the figure.When drive sprocket [1] was done the cw transmission, flywheel [2] drove backshaft skin [6] and clockwise rotates.When drive sprocket [1] was done the conter clockwise transmission, flywheel [3] drove backshaft skin [6] and clockwise rotates.Drive sprocket [1], flywheel [2], transition wheel [4] are engaged on the closed-loop inboard that chain [5] is formed, and flywheel [3] is engaged on the closed-loop outside that chain [5] is formed.Best and the same axle mounting of drive sprocket [1] of transition wheel [4].
Claims (3)
1, but a kind of back-pedal drives automatic speed-changing bicycle, it is characterized in that its transmission device is made up of drive sprocket [1], two flywheels [2] [3], transition wheel [4] and chain [5].
2, bicycle according to claim 1 is characterized in that drive sprocket [ 1 ], flywheel [ 2 ], transition wheel [ 4 ] are engaged on the closed-loop inboard that chain [ 5 ] is formed, and flywheel [ 3 ] is engaged on the closed-loop outside that chain [ 5 ] is formed.
3, bicycle according to claim 1 and 2 is characterized in that the number of teeth of two flywheels is unequal.
