Abstract
The utility model discloses wheel center bidirectional differing speed driver, which is characterized in comprising a driving shaft, a connecting shaft, a big gear, a small gear, a big chain gear, a small chain gear, a shell driving ratchet wheel, and a shaft driving ratchet wheel. Wherein the driving mechanism consists of the big gear, the small gear, the big chain wheel and the small chain gear. The inner and outer sleeves of the shaft driving ratchet wheel are fixed with the driving shaft and a wheel boss, while the inner and outer sleeves of the shell driving wheel are fixed with the wheel boss and the small chain wheel. The utility model has advantages that the speed-change operation is very convenient and needs no clutch and can be installed in either the front wheel or the back wheel of a bicycle.
Description
The utility model relates to a kind of bicycle driving mechanism, the two-way friction speed actuator of particularly a kind of core wheel.
At the characteristics that existing bicycle rear drives, front-wheel leads, the applicant has designed a kind of f-w-d of novel concept, the bicycle of trailing wheel guiding, and has applied for utility model patent, and number of patent application is 00241174.1.But the employed transmission device of this bicycle can not be made friction speed and drive, and its wheel hub axis and vehicle frame are fixed, and axis is not done axle drive shaft.
The purpose of this utility model provides a kind of two-way friction speed actuator of core wheel of variable-ratio.
The purpose of this utility model is achieved through the following technical solutions: the two-way friction speed actuator of a kind of core wheel is characterized in that it comprises axle drive shaft, coupking shaft, big gear wheel, miniature gears, hinge wheel, minor sprocket, shell driving pawl and axle driving pawl; The overcoat and the minor sprocket of shell driving pawl are fastening, and cover is fastening with wheel hub in it, and the overcoat of axle driving pawl and the opposite side of wheel hub are fastening; Cover is fastening with axle drive shaft in it, and big gear wheel is fixed on the axle drive shaft, and miniature gears and hinge wheel are fixed on the coupking shaft, and big gear wheel is meshed with miniature gears, and hinge wheel cooperates by chain gear with minor sprocket.The utility model principle of work is: when axle drive shaft is just changeing, the inside and outside cover of axle driving pawl all just changes, thereby driving wheel hub just changes, and big gear wheel is just being changeed the counter-rotating of drive miniature gears, miniature gears drives coupking shaft and then drives the hinge wheel counter-rotating, and hinge wheel drives the minor sprocket counter-rotating, and minor sprocket drives shell driving pawl mantle reversal, at this moment, minor sprocket is inoperative to wheel hub.When axle drive shaft counter-rotating (reversing), the big gear wheel counter-rotating, miniature gears, hinge wheel, minor sprocket just change then, and the inside and outside cover of shell driving pawl just changes, just changes thereby drive wheel hub, and the interior cover counter-rotating of axle driving pawl, overcoat just changes.When the axle drive shaft transfixion, wheel hub can just change, can be static, but can not reverse other part stationary.
The utility model compared with prior art, its remarkable advantage is: 1, variable speed operation is extremely convenient, and not need to install power-transfer clutch, forward rotation be cruising speed, backward rotation can realize that speed change rotates.2, this driver train both can be installed on the front-wheel, can be installed in again on the trailing wheel, also can install simultaneously on front and rear wheel, and the bicycle that is equipped with this actuator both can be made walking-replacing tool, can make body-building apparatus again.
The utility model is described in further detail below in conjunction with drawings and Examples:
Accompanying drawing is the utility model structural representation.
Embodiment: the two-way friction speed actuator of core wheel that the utility model is made, it comprises axle drive shaft 1, coupking shaft 2, big gear wheel 3, miniature gears 4, hinge wheel 5, minor sprocket 6, shell driving pawl 7 and axle driving pawl 8.Be fixed with foot-operated in the both sides of axle drive shaft 1, the interior cover and the axle drive shaft of axle driving pawl 8 are fixed, overcoat and wheel hub 9 are fixing, the interior cover of shell driving pawl 7 and wheel hub 9 are fixing, overcoat and minor sprocket 6 are fixing, big gear wheel 3 is fixing with axle drive shaft 1, and miniature gears 4 and hinge wheel 5 are fixing with coupking shaft 2, and big gear wheel 3, miniature gears 4, hinge wheel 5, minor sprocket 6 form transmission devices.
