Abstract
The utility model provides a wheel electric boosting device which can be used for the existing general bicycles, tricycles, wheelchairs and various electric vehicles. An accumulator (1) is used as a power supply. A motor (2) is fixed on one side of the wheel shaft. The utility model is characterized in that a motor output shaft is manufactured to be a shaft gear (3) by which a big gear (4) connected tightly to the outer shell (6) of a clutch is driven to rotate; a star wheel (8) is driven to rotate by the outer shell of the clutch through a roller ball (7) or a ratchet wheel pawl; motive power is transmitted to a seat plate (13) connected with a wheel chain (15) by the star wheel, and so the wheels are driven to rotate forward. The boosting device has the advantages of simple structure, easy installation and easy repair.
Description
The utility model is a kind of electric booster that is used on the vehicle.
Known bicycle use electric power servo-unit, motor-driven power is passed to rear axle by driving chain behind gear reduction, and its member is many, complex structure, cost is higher, and efficient is lower, and easy break-down is difficult to for the customer accepts, thereby can't promotion and implementation.
The Electric booster that the utility model provides a kind of wheel to use, its simple in structure, dependable performance, efficient height can be applicable on bicycle, three-wheel vehicle, wheel Wheel-chair and other elec. vehicles.
The purpose of this utility model realizes like this: motor is contained on the vehicle frame, the shaft gear of motor and big gear wheel engagement, big gear wheel (ring gear) links together with a clutch outer member again, the power-transfer clutch star-wheel is connected with attic base, the spoke of wheel is connected by fastener again with the attic base of this power-transfer clutch, as bolt screw etc.
The purpose of this utility model also realizes by following measure: between power-transfer clutch star-wheel and attic base by riveting or weld together, between the outer and star-wheel of power-transfer clutch both but the click transmission, also can be by roller in the skewed slot on the star-wheel or ball slip transmission; It is that one-level is slowed down that the shaft gear of motor drives the big gear wheel rotation, can mesh a duplex gear between axle tooth and big gear wheel, constitutes double reduction, to obtain bigger transmitting ratio.
The servo-unit that the utility model provides can be directly installed on the existing various vehicle.Whole device can be contained in the wheel left side, and clutch sleeve is on left floral disc.Accumulator jar can be contained in the hind axle both sides, or elsewheres such as clothes hanger both sides or spider both sides.
Description of drawings: Fig. 1 is for being contained in scheme drawing on the ordinary bicycle according to the wheel Electric booster that the utility model proposes.
Fig. 2 is for being contained in the structural representation on the trailing wheel left side floral disc (10) according to the Electric booster that the utility model proposes, wherein power-transfer clutch is the slip clutch of embodiment 1 usefulness.
Fig. 3 is the power-transfer clutch forward view of embodiment among Fig. 2.
The structural representation of Fig. 4 for being loaded on the trailing wheel according to the wheel Electric booster embodiment 2 that the utility model proposes.Its used power-transfer clutch is the roller power-transfer clutch.
Fig. 5 is the forward view of power-transfer clutch shown in Figure 4.
Describe in detail below in conjunction with embodiment and accompanying drawing.
Embodiment 1 as shown in Figure 1, accumulator jar (1) is fixed in the clothes hanger side, or on the bicycle tripod, electrical motor (2) is fixed between the chain stay and upright fork of bicycle.The shaft gear of motor (3) meshes than big gear wheel (4) with one, and big gear wheel is associated in bolt (5) with clutch outer member (6) again, and power-transfer clutch star-wheel (8) tightens together by bolt (9) with attic base (13).Cylindrical at star-wheel has five skewed slots equably, in roller or ball (7) are housed.Attic base (13) is installed on the bicycle rear axle left side floral disc (10), with bolt (14) big end of attic base and spoke (15) is linked together, and back-up ring on the attic base small end (12) and axle bumper (11) block the axial motion of shell.The clutch configuration of embodiment 1 is seen Fig. 2 and Fig. 3.
The working process of this power-transfer clutch is: when power connection, shaft gear drives big gear wheel and clutch outer member (6) rotates counterclockwise, shell promotes roller (7) and enters the skewed slot small end of star-wheel and make roller and star-wheel wedge dead, power passes on the star-wheel by roller, drive star-wheel and attic base and rotate together, thereby drive wheels travels forward.When without the motor power-assisted, people's pedal power drives the wheel left-hand revolution by chain, this moment, attic base and star-wheel rotated thereupon, promote roller and enter the big end of skewed slot, because of the end size is greater than the roller diameter greatly, roller can be free to slide in skewed slot, at this moment shell and roller slide relative, can not drive shell and rotate, that is to say not can be to the wheel generation resistance that advances.
Fig. 4,5 be shown in power embodiment 2.Be a kind of rolling power-transfer clutch, its shell (6) still is associated in by bolt (5) with big gear wheel (4), but links to each other for the click transmission between shell (6) and the star-wheel (8): shell has ratchet (22) engagement on a circle internal tooth and the star-wheel.Respectively there is the very smooth alley of a circle two inboards about shell, and antifriction-bearing box (18) is arranged on it, and the antifriction-bearing box left side is a silk retaining (19), silk retaining internal diameter is processed with screw thread, it is screwed on the star-wheel (8), and antifriction-bearing box the right is a flat retaining (17), and it and star-wheel rivet together securely.The pad (20) of regulating bearing space is contained between star-wheel (8) and silk retaining (19).Star-wheel is sleeved in the left sabot of wheel rear axle, is integral with riveting or solid welding between attic base (13) internal diameter and the star-wheel, and making it does not have relative motion.Rubber cushion (16) pad can strengthen contact friction force between attic base (13) and spoke (15).The work relationship of this power-transfer clutch is: flat retaining (17), silk retaining (19) and attic base (13) all are to be contained on the star-wheel (8), when shell (6) rotates counterclockwise under the drive of big gear wheel (4), at this moment shell internal tooth and ratchet (22) engagement, propulsive effort passes on the star-wheel (8) by ratchet, by attic base (13) and spoke (15), drive wheel and move ahead again.When without the electric power power-assist, when stepping pedal, star-wheel (8), flat retaining (17) and silk retaining (19) can rotate with wheel, and the slide relative of shell internal tooth and ratchet (22) generation at this moment that is to say that shell can produce relative rotation with star-wheel.
Between shaft gear (3) and big gear wheel (4), can mesh a duplex gear (21), become double reduction, increased motor-driven power.
With conventional approach processing, the number of teeth can be less to 5 in the general-duty gear-hobbing machine for a kind of thin thickness of the utility model, the printed circuit motor that size is less, its tooth, if adopt special process, the number of teeth can be less to 2, thereby the transmitting ratio that one-level is slowed down is just very big.
Motor is powered by accumulator jar, and voltage carries out stepless or step-governor d by known electric control system controls.
