Abstract
The utility model relates to a driving device of a rat-cage type friction tyre for an electric bicycle, the driving device of which is composed of a motor, a shaft coupling, a rat cage, bearing supporting seats, a hanging bracket, etc. The utility model is characterized in that a driving shaft of the motor is connected with a middle shaft of the rat cage by the shaft coupling; a shaft of the rat cage is arranged on the two bearing supporting seats by a bearing rack; the bearing supporting seats are hung with a bracket by a hanging shaft; the shaft of the rat cage and the hanging shaft form an inclined angle with a vertical line of the ground; the bracket is connected with a bracket of the bicycle. The utility model has the advantages of novel design, simple structure, and convenient installation and operation.
Description
The utility model relates to a kind of actuating device, especially a kind of Electrical Bicycle squirrel-cage tire actuating device that rubs.
At present, Electrical Bicycle is national acceptance as a kind of vehicle of pollution-free, low noise day by day, has vast potential for future development.The type of drive of Electrical Bicycle is the simplest with the tire formula of rubbing.The wheel that rubs is easily stopped up teeth by earth or finger stone and produces and skid influence driving efficient but the tire that rubs drives.
The deficiency that the purpose of this utility model exists at prior art and a kind of Electrical Bicycle squirrel-cage tire actuating device that rubs is provided, it has avoided the blocked phenomenon of skidding of teeth, has improved drive efficiency and adaptivity.
The purpose of this utility model is achieved in that a kind of Electrical Bicycle squirrel-cage tire actuating device that rubs, it is by actuating device, controller, formations such as battery, its actuating device is by electrical motor, coupler, mouse cage, bearing brackett, compositions such as suspension holdfast, the transmission shaft of its electrical motor is connected with the tween drive shaft of mouse cage by coupler, mouse cage is captiveed joint with tween drive shaft by the many cylindricality cage muscle of arranging symmetrically and evenly and is cage modle, the mouse cage axle by bearing frame on two bearing bracketts, bearing brackett is hung by its suspended axle that is equipped with above and suspension holdfast, line perpendicular to the ground is 0-15 ° of angle of inclination between mouse cage axle and the suspended axle, suspension holdfast is connected with cycle rack, and mouse cage and cycle casing are pressing.Its principle of work: power to electrical motor by the storage battery via controller that bicycle is provided for oneself, rotate the mouse cage axle by motor shaft by coupler, mouse cage rotates subsequently, because of mouse cage and cycle casing closed contact, and mouse cage rotating drive cover tire rotates and bicycle is advanced; When local friction drag in the face of cycle wheel increases, because line perpendicular to the ground is to tilt the action of gravity that installation is produced between the mouse cage axle of driver train and the suspended axle, automatically the thrust that cycle casing is produced increases, this moment, motor speed reduced, the driving torque of motor increases, thereby the propulsive effort of wheel increased, to overcome ground-surface resistance; When reduce in the face of the wheel friction drag locality, the rotating speed of motor and wheel increases, wheel makes mouse cage and driver train reduce the thrust of wheel to the antagonistic force of mouse cage, reduce the propulsive effort of wheel is also corresponding, the mouse cage that is driver train adapts with the resistance size of ground in the face of wheel all the time to the thrust of wheel and propulsive effort, and just driver train has the comformability of self.Cage-shaped structure in the driver train is open, can rapidly earth and the finger stone jettisoning of filling in not produced obstruction, thereby has guaranteed the adhesive ability between mouse cage and the cover tire.
The utility model is simple in structure, and cost is low, can be installed in easily on the front-wheel of bicycle or the trailing wheel to have general practical reference value.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is cage-shaped structure figure of the present utility model.
Fig. 3 is a scheme of installation of the present utility model.
As Figure 1-3, a kind of Electrical Bicycle squirrel-cage tire actuating device that rubs, it is by actuating device (18), controller (17), battery formations such as (16), its actuating device (18) is by electrical motor (1), coupler (2), mouse cage (7), bearing brackett (4,11), suspension holdfast compositions such as (10), it is characterized in that: electrical motor (1) is fastened on the bearing brackett (4) by gasket ring (3), the transmission shaft (14) of electrical motor (1) is connected with the tween drive shaft (6) of mouse cage (7) by coupler (2), mouse cage (7) is captiveed joint with tween drive shaft (6) by the many cylindricality cage muscle of arranging symmetrically and evenly (15) and is cage type, mouse cage axle (6) is by bearing (5,12) frame is at two bearing bracketts (4,11) on, bearing brackett (4) is affixed with bearing brackett (11), bearing brackett (4,11) hang by its suspended axle that is equipped with above (8) and suspension holdfast (10), line perpendicular to the ground is 0-15 ° of angle of inclination between mouse cage axle (6) and the suspended axle (8), suspension holdfast (10) is connected with cycle rack (9), and mouse cage (7) is pressing with cycle casing (13).
