Description
Technical field
The present invention relates to bicycle speed-regulating methods and apparatus, and in particular to a kind of speed regulating method of moped and speed governing
Device.
Background technology
Mountain bike has the characteristics that adjustable speed, bicyclist can be adjusted according to the needs of itself and road conditions, with
Faster speed or more effortless impression of riding are obtained, it is wide popular.Originally, people in order to kickster sense of riding
By mountain bike is mainly used for riding in mountainous region and waste Yezhong, and frequently appears in mountain bike activity, has attracted large quantities of
The fan that rides；Over time, mountain bike is even more the market and space for gradually capturing common bicycle, usual
Life and trip in, more and more people switch to mountain bike of riding by common bicycle of riding.Wherein, in order in ride
In it is laborsaving, gear is often adjusted to low grade by bicyclist, still, speed can higher gears speed it is many slowly.It is not added in bicyclist
In the case of large driving force, if it is desired to faster speed, it is necessary to by external force, need a kind of novel mountain bike thus.
Power-assisted multi-speed bicycle using battery as auxiliary power source, and has power assist system, manpower may be implemented
It rides with electric power integrated.The operation principle of power-assisted multi-speed bicycle is：The foot of bicyclist by driving pedal and crank, to
Chain wheel is driven to drive chain rotation；When speed governing, the push rod of drive speed adjustor is swung so that conductor rope pulls derailleur, thus by chain
Item transfers next flywheel to from current flywheel, completes gear switch；When the distance that conductor rope pulls is bigger, derailleur stirs chain
The amplitude of item is also bigger.Wherein, after completing switching, acting on the driving force of crank can change, in power assist system
Pressure sensitive system senses the variation of the driving force of crank, internal control system is then passed to, when the driving force of crank reaches
When to certain value, control system sends out instruction to assist motor, and then assist motor starts, by power output system by power
It passes on flywheel；It is the driving force of people and the driving force of motor respectively at this point, gathering together there are two types of driving force on flywheel.
If the driving force of bicyclist is constant, the speed of bicycle will increase；If bicyclist wants to keep bicycle speed not
If change, bicyclist can reduce pedal force accordingly, and bicycle realizes assist function.
Usually, the small flywheel of diameter represents top grade, the big flywheel of diameter represents low grade, for example, diameter is from small to large
The gear that flywheel represents is 5,4,3,2,1.When bicyclist encounters the road conditions of upward slope or wants to reduce the pedal force of itself and increase
When stepping on frequency of foot needs to switch on the big flywheel of diameter from the small flywheel of diameter come drive chain by governor.For general
Logical multi-speed bicycle from top grade in shelves speed-change process, can once cross flywheel to adapt to more complicated road conditions
Series is The more the better, thus can across shelves adjustings, such as can directly be transferred to gear 1 from gear 5.But voluntarily for power-assisted
Vehicle, across shelves adjustings can bring problems with：Significantly reduce before comparing gear shift due to the transmission after shelves are adjusted, so switching
Moment afterwards, speed remains unchanged under effect of inertia, and ride, the rotating speed of crank and chain wheel is then actively accelerated, bicyclist is very
It is susceptible to and steps on sky phenomenon so that the foot of bicyclist disappears to the power that crank applies, only the inertia force of remaining crank so that crank
Independently rotating, and power assist system is to control whether output power by foot pressure suffered on crank, steps on sky
The phenomenon that can make the power instantaneous trip of power assist system, and power assist system can normal work when then normally riding
Make, this results in the motor in gear shift that can ceaselessly switch between startup and closing, is caused in this way to assist motor and battery
Very big damage, influences service life.In addition, across shelves speed changes can also make the appearance of chain stress significantly be mutated, so
Chain also will produce a degree of damage.
Invention content
It is above-mentioned it is an object of the invention to overcome the problems, such as, a kind of speed regulating method of moped, the tune are provided
Fast method can to avoid in gear shift assist motor continually start and close, to extend assist motor and for the use of battery
Service life.
The present invention also provides a kind of governors of moped.
The purpose of the present invention is achieved through the following technical solutions：
A kind of speed regulating method of moped, includes the following steps：
By stirring governor so that conductor rope drives derailleur, and chain is allocated on next flywheel by derailleur, completes
Gear is adjusted；The gear adjusting includes being transferred to high tap position from low-grade location and being transferred to low-grade location from high tap position；It is transferred in high tap position
In low-grade location, it is primary often to stir governor, and chain only moves a gear, is moved on the flywheel high from current gear next
On the flywheel of an adjacent low gear.
The preferred embodiment of the present invention, wherein the direction of each governor toward speed governing is stirred, and after gear switch, is adjusted
Fast device is resetted toward opposite direction, could be stirred next time.When due to each speed governing, governor has to negative direction reset
After could be stirred next time, so as to avoid short time continuous several times from stirring governor, and then avoid chain short
The phenomenon that constantly switching along flywheel in time allows assist motor and for battery frequent start-stop to avoid stepping on sky.
A kind of governor of moped for realizing above-mentioned speed regulating method, including be fixed on the shell of governor
Holder, be located on holder shaft, flywheel, for driving push rod that flywheel rotated, for limiting push rod rotation
Angle limiting plate and detent mechanism for being positioned to flywheel；
