All the parts form a double-geared drive. The left and right swinging driving forces of the swinging axis are changed into the unilateral continuous rotating of the wheel shaft. The utility model has the advantages of large transmission ratio, capability of reducing the size of the mobile device, balanced driving torque, high transmission efficiency, good versatility, etc.

Description

A kind of manpower drives the driver of mobile devices

The utility model belongs to a kind of parts of Manpower driver, particularly driver.Be applicable to bicycle, roller skate, skateboard, wheelchair, perambulator, Self-propelling boat etc. voluntarily voluntarily voluntarily.

Existing rickshaw adopts the crank up chain drive mostly, owing to only adopt the one-level transmission, so velocity ratio can not be big, about about 3: 1, for the forward travel distance that makes one week of crank up remains in 6～8 meters scopes, need wheel diameter is remained on 40～70 centimetres, it is huger that this just causes vehicle body can not shorten with car body; In addition, owing to its driving arm of force of rotation process of crank up mechanism is done cyclically-varying and had the dead point, so its driving moment is a pulse state.For addressing the above problem, schemes such as the swinging transmission mechanism that people have proposed, folding bike all can not achieve the goal more satisfactoryly; The roller skate voluntarily that proposed at present also all exist because of intermittent type drives and make the jiggly shortcoming of output torque, or fail to reach problem such as the travelling speed of hope or running efficiency difference and can not reach real practical purpose.

The purpose of this utility model provides the driver that a kind of improved manpower drives mobile devices, and its velocity ratio is big, can make the mobile devices volume size little, and driving moment is steady, and running efficiency is good.

The utility model is achieved in that a kind of manpower drives the driver of mobile devices, it is characterized in that comprising lower base and device swing axis thereon, the left-right orientation clutch, left and right sides cone gear, central shaft, size center cone gear, wheel shaft and wheel shaft cone gear, wherein central shaft passes lower base and by bearing fixing, little center cone gear is being adorned in its end that is positioned at upper pedestal, big center cone gear is being adorned in its end that is positioned at lower base, wheel shaft is placed through lower base and by bearing fixing, adorning wheel shaft cone gear on it with the engagement of big center cone gear, swing axis is placed through upper pedestal and by bearing fixing, adorning the left-right orientation clutch on it and do to be driven with left and right sides cone gear respectively by the left-right orientation clutch and cooperate, left and right sides cone gear is respectively from left and right sides Liang Chu and little center cone gear engagement.

The directional clutch of such scheme can be the friction rolling component type, also can be click formula etc.

Such scheme is owing to adopt the secondary gear transmission, and velocity ratio can be about 16: 1, thus bicycle when keeping original travelling speed, wheel diameter only needs 16 centimetres, this can make vehicle body shorten and volume-diminished.Owing to driving force adopts the swing input by the left-right orientation clutch, so the variation of the driving arm of force is very little and do not have the dead point, its output torque is steady, running efficiency is good.Simultaneously because relatively rotating of last lower base do not influence drive connection, the direction of swing axis can arbitrarily change, so this driver is good to the versatility that the manpower of various different modes drives mobile devices, as be applicable to that two take turns or tricycle, skateboard, roller skate, wheelchair, perambulator, Self-propelling boat etc. voluntarily automatically automatically.

Below in conjunction with accompanying drawing the utility model is done to describe more specifically.

Fig. 1 is the vertical profile schematic representation of a kind of scheme of the utility model.

Fig. 2 be Fig. 1 A to B to view.

With reference to Fig. 1～Fig. 2, this driver, feature comprises upper pedestal 1, lower base 2 and device swing axis 3 thereon, left side ratchet mechanism 4, right ratchet mechanism 5, left side cone gear 6, right cone gear 7, central shaft 8, little center cone gear 9, big center cone gear 10, wheel shaft 11 and wheel shaft cone gear 12, wherein central shaft 8 passes lower base 1,2 and by bearing 13,14 fix, little center cone gear 9 is being adorned in axle 8 ends that are positioned at upper pedestal 1, big center cone gear 10 is being adorned in axle 8 ends that are positioned at lower base 2, wheel shaft 11 is placed through lower base 2 and by bearing 15,16 fix, adorning wheel axle gear 12 on the axle 11 with 10 engagements of big center cone gear, swing axis 3 is placed through upper pedestal 1 and by bearing 17,18 fix, adorning left and right sides ratchet mechanism 4 on the axle 3,5 ratchet part, ratchet portions is located at left and right sides cone gear 6,7 inner ring also partly cooperates left and right sides cone gear 6 respectively with ratchet, 7 respectively from left and right sides Liang Chu and 9 engagements of little center cone gear.

During use, last lower base 1,2 transmissions are adjusted to the relative position of requirement, fix, be connected with concrete mobile devices by the correct position of last lower base 1,2 with fastening piece, load onto wheel in wheel shaft 11 ends, load onto the driver part of riding boogie board and so in the end of swing axis 3.When the clockwise transmission of swing axis 3, left ratchet mechanism 4 drives left cone gear 6 and rotates, and at this moment wheel shaft 11 clockwise rotates; When swing axis 3 rotated counterclockwise, right ratchet mechanism 5 drove right cone gear 7 and rotates, and at this moment wheel shaft 11 still clockwise rotates, and moved so step on rotation by the both sides of axle 3, and the wheel on just can live axle 11 travels continuously towards a direction.
