Abstract
The utility model belongs to a transmission mechanism of a measuring apparatus. The utility model is characterized in that a rotating part can synchronously rotate following a center shaft and can move along the axial direction, the periphery of which is fixed with strip-shaped permanent magnet with equally intervals; the end part of a floating rod which is supported by a spring in a seat sleeve is fixed with a transverse rod, one end of the transverse rod is provided with a rolling wheel which is engaged with the end surface of the rotating part, and the other end of the transverse rod presents a shifting fork shape; two forks are fixed with permanent magnet sheets in parallel. The utility model has the advantages that the torque of the center shaft can be more accurately and stably monitored; the action time fit of two sensor transmission mechanisms which monitor the angular speed and the torque of the center shaft is not needed regulating; because soft coordination intervenes power-assistance when a moped is ridden, an ideal power-assisted effect that the ratio of electric power-assistance to pedal driving force is one to one can be accurately achieved.
Description
The utility model belongs to the gear train of measurement mechanism.
The assist motor of Moped Scooter acts on chain-wheel mechanism moderately and at the right moment, needs two controlled variable the most basic, promptly middle axis angular rate and torque.Its variable of monitoring adopts magnetoelectric sensor mostly in the prior art, obtain the recurrence interval value of relative angle speed variable and the electric current changing value of corresponding torque variable respectively, the gear train of angular velocity monitoring sensor is to disturb the magnetic tongue and groove in the periphery setting of the ferromagnetism rotary part that is synchronized with axis, commentaries on classics is then adopted the chain tension gear train apart from monitoring sensor, although chain tension mechanism is provided with the compensation correcting device, but chain slack, shake almost are inevitably, so the accuracy of torque monitoring and less stable.In addition, the difficult adjustment of two sensors gear train cooperation action time, the power-assisted intervention that is reflected at the actual effect existence of riding coordinates to feel relatively poor with foot-driven.
The purpose of this utility model provides a kind of gear train that can overcome the Moped Scooter monitoring sensor of above-mentioned defective.
The purpose of this utility model is achieved through the following technical solutions: rotate the also rotary part of energy axial displacement synchronously with axis, its periphery is fixed with equally spaced strip-shaped permanent-magnet iron, be fixed with Hall switch sensor at its relative tertiary location, be fixed in the cover for seat of supporting mass and floating lever arranged by spring-loaded, its end is fixed with cross bar, its end is provided with the roller that engages with the rotary part end face, the other end is the fork shape, two fork secured in parallel have the permanent magnetism sheet, and the locus in the middle of the two permanent magnetism sheets is fixed with linear hall sensor.
Said rotary part is a joint element, it is made of the two halves joint element that is sleeved on axis with spiral interlocking interface, clutch coupling and axis one way engagement that the inboard feather key of half joint element a connects, and supported by the support seat and the cluster spring that are set in axis, half joint element b is supported on axis and housing by bearing respectively, and half joint element a end is fixed with the wheel rim of bottom band shoulder;
Fixing of said strip-shaped permanent-magnet iron is that the wheel rim surface of half joint element a is fixed with plastic ferrule, and strip-shaped permanent-magnet iron plug-in mounting is fixed in this lasso axial socket;
Said each Hall element is fixing by its pin supporting that is welded on control circuit board.
Below in conjunction with drawings and Examples explanation the utility model.
Accompanying drawing 1 the utility model diagrammatic cross-section
Fig. 1 is a kind of electric assisted bicycle driver assembly, half joint element a15 can rotate also synchronously with axis 1 and can produce axial displacement among the figure, this half joint element end is fixed with wheel rim 7, plastic ferrule 4 is fixed its surface, strip-shaped permanent-magnet iron 5 plug-in mountings are fixed in the uniform slot of lasso, Hall switch sensor 6 by its pin support fixation that is welded on circuit board in the relative tertiary location of strip-shaped permanent-magnet iron.It is housing that cover for seat 14 is fixed in supporting mass, and floating lever 12 is bearing in the cover for seat by spring 13, is provided with register pin and cotter way between floating lever and the cover for seat, makes floating lever have float cap and can not eject.The floating lever upper end is fixed with cross bar 8, one ends roller 11 is housed, and engages with the lower shoulder of wheel rim 7, and the other end is the shift fork shape, the permanent magnetism sheet 10 that encapsulation is parallel to each other in two forks, and the cross bar of illustrated embodiment is a working of plastics.Linear hall sensor 9 is also by the locus of the pin support fixation that is welded on circuit board in the middle of two permanent magnetism sheets.
The rotation and the axial displacement of half joint element a of present embodiment and wheel rim 7 thereof, lasso 4 are illustrated referring to Fig. 1, half joint element a, the b of axis 1 suit is that label 15,2 constitutes joint element by its spiral interlocking interface 3, clutch coupling 18 and axis one way engagement that the inboard feather key of half joint element a connects, it is also supported by support seat 17 that is sleeved on axis and symmetrically arranged cluster spring 16, and half joint element b then is supported on axis and housing 19 by bearing respectively.The foot-driven driving-chain is an axis--clutch coupling--feather key--half joint element a--half joint element b--sprocket wheel.Clearly, axis is fixed in half joint element a when rotating wheel rim, lasso will rotate thereupon, and equally spaced strip-shaped permanent-magnet iron 5 will act on Hall switch sensor 6, make control circuit obtain representing in the train of impulses of axis angular rate.When foot-operated driving is afterburning, zygosporic spiral interlocking interface presents the engagement of sliding, tangential force that the direction that is produced is opposite and axial force act on the two halves joint element respectively, half joint element b is transmitted to sprocket wheel with power to be continued to drive, half joint element a is stressed then to be compressed its supporting cluster spring and produces axial displacement, big more its displacement of reinforcing is big more, the lower shoulder of wheel rim 7 promotes cross bar 8 by roller 11 and does corresponding displacement as a result, and permanent magnetism sheet 10 formed permanent magnetic field generation respective change, the current value of shaft torque variable quantity in 9 output expressions of linear hall sensor.
The beneficial effects of the utility model show that the Stability and veracity of shaft torque is better in the monitoring, and two pass Cooperating the action time of sensor transmission mechanism does not need to adjust, and power-assisted gets involved soft the coordination when riding, can be accurately The ratio that reaches electric boosted and foot-operated driving force is 1: 1 desirable power-assisted effect.
