The physical construction of Moped Scooter monitoring axis moment of torsion
The utility model belongs to the actuating device of rickshaw, especially relates to the physical construction of Moped Scooter monitoring axis moment of torsion.
Axis is driven by foot-operated, its cireular frequency and moment of torsion are the important parameters of control assisted electric machine, at present, the Moped Scooter of domestic production is parameter of monitoring angle speed only, disturb magnetic cell with the rotary gadget setting that foot-operated axis is in transmission connection, monitoring sensor corresponding with it is transformed to electric signal with the mechanical quantity of rotating speed, and by the fuzzy control of electrical controller enforcement to electrical motor, its defective is that electrical motor can not give power-assisted comparatively accurately according to the actual torque of axis.External its torque monitoring physical construction of Moped Scooter of producing is to be the labyrinth of core with the star cycloidal reducer, only also is difficult to be approved by domestic consumption market with regard to its productive costs.
It is comparatively simple that the purpose of this utility model provides a kind of structure, the physical construction of the Moped Scooter monitoring axis moment of torsion that productive costs is low.
Above-mentioned purpose is obtained by following technical scheme: the power-assisted jacket casing engages with the not gear transmission of motor gear speed reduction gearing, foot-operated jacket casing engages with middle shaft drive, two jacket casings constitute joint element by the intermeshing helical surface interlocking of end face interface, and wherein foot-operated jacket casing is provided with resilient mounting; Guide rod by housing slideway resilient mounting is provided with the dead axle perpendicular with it, and this dead axle one end is equipped with and rides the roller of jacket casing annular boss frictional engagement, and other end plane is provided with fixedly magnetic sheet, and the housing relative with magnetic sheet is equipped with the torque monitoring sensor.The resilient mounting of said foot-operated jacket casing, it is the guidepost that is symmetrical arranged pocketed springs with its spring perch that rotates synchronously, each the identical compression spring of hardness that is set in guidepost is engaged with foot-operated jacket casing by its support ring plane, and spring perch is provided with the fixed pedestal of synchronous rotation;
The resilient mounting of said guide rod is that the through hole that two bearings of housing are provided with the guide rod bearing fit is the guide rod slideway, and guide rod bottom through hole is provided with cover for seat and the spring that is threaded, and cover for seat is provided with the adjustable bolt that engages with spring;
Said foot-operated jacket casing, its outside is fixed with the sheave of the uniform vertical teeth groove of periphery, is fixed with cireular frequency monitoring forwarder with its corresponding shell;
The annular boss of said foot-operated jacket casing can be the fixing annulus of sheave bottom face.
Further specify the utility model below in conjunction with embodiment and accompanying drawing thereof.
Accompanying drawing 1 example structure generalized section accompanying drawing 2 joint element helical surfaces interlocking interface scheme drawing accompanying drawing 3 joint elements produce the longitudinal travel scheme drawing
Embodiment illustrated in fig. 1, power-assisted jacket casing 7 is fixed in not gear 8 inboards by the bearing 5 and built-in bearing 10 supportings of housing end plug 6 with its ingear free-wheel clutch 9, and the second gear reduction unit structure of electrical motor 28 also comprises gear 29,30,31.Foot-operated jacket casing 12 feather keys connect free-wheel clutch 11, this power-transfer clutch and axis 1 one way engagement, the lower end of the foot-operated jacket casing of diagram by be set in axis 1 and with spring perch 26, symmetrically arranged 6 guideposts 25 of its bearing fit, be set in the identical compression spring 24 of 6 hardness of guidepost and realize resilient mountings, the spring perch bottom engages with bearing 27 inner rings that support axis, i.e. the fixed pedestal that rotates synchronously.
Power-assisted jacket casing 7 is provided with intermeshing helical surface interlocking interface with foot-operated jacket casing 12 opposing end faces and forms joint element, and interfacial structure is launched signal as Fig. 2.
Foot-operated jacket casing 12 outsides are fixed with the poor wheel 14 of the uniform vertical teeth groove of periphery, and the housing relative with it is equipped with cireular frequency monitoring forwarder 13, and sheave 14 lower surfaces are fixed with annulus 15, and this annulus also can be directly arranged in foot-operated jacket casing becomes its annular boss.
Two bearings of the small end of housing lid 22 be provided with concentric and with the through hole of guide rod 18 slide joint be the guide rod slideway, guide rod bottom through hole is provided with the cover for seat 21 that is threaded and the spring 20 of support guide rod, realize the resilient mounting of guide rod, cover for seat 21 is provided with the adjustable bolt 23 that engages with spring, the guide rod upper end is provided with perpendicular dead axle 16, this right-hand member is equipped with the roller 19 with annulus 15 frictional engagement, the lower plane of left end is adhesively fixed with magnetic sheet, and the small end relative with it is covered with torque monitoring sensor 17.
Physical construction of the present utility model has the function of transmission, takeoff output and transmission axis moment of torsion concurrently, its course of action is as follows, the stressed rotation of axis, the chain drum core dish 3 and the chain drum 4 that are fixed in power-assisted jacket casing 7 ends also rotate thereupon, the free-wheel clutch 9 of this moment is a disengaged condition, and said process is foot-operated driving process.When electrical motor 28 starts, the not gear 8 of its gear reduction will be transmitted in axis 1 by free-wheel clutch 9, and the free-wheel clutch 11 of this moment is a disengaged condition.The moment of torsion combined action that moment of torsion that foot-operated axis produces and electrical motor produce is power-assisted in axis and drives, afterburning as if foot-operated in this process, as shown in Figure 3, to produce opposite tangential force F of direction and F ' and axial force Q and Q ' on the zygosporic helical surface mesh inclined plane, wherein power F and Q act on foot-operated jacket casing 12, power F ' and Q ' act on power-assisted jacket casing 7, power Q will make foot-operated jacket casing resilient mounting compression, promptly this jacket casing keeps ingear to produce longitudinal travel simultaneously, and by annulus 15, roller 19, dead axle 16 drives guide rod 18 corresponding displacements, the fixing magnetic sheet of dead axle and the distance of torque monitoring forwarder are changed, and the size of its variable in distance is directly proportional with the axis torque.The electric signal of the reflection change in torque that sensor produced send electrical controller, and its output changes control motor output.
The sheave 14 that foot-operated jacket casing 12 is fixed rotates with this jacket casing, and the axis change in rotational speed is by cireular frequency monitoring sensor 13 output corresponding electric signal.
The utility model compared with prior art structure is comparatively simple, and the processing and fabricating cost is lower, can accurately carry For the axial mechanical displacement that chain wheel axle torsion changes, can reach foot-operated driving force is 1: 1 with electric boosted ratio Comparatively desirable power-assisted effect.
