Description

The bicycle taximeter

The utility model relates to a kind of bicycle taximeter.

At present, no matter be that racing car or mountain bike or ordinary bicycle all are not equipped with taximeter, this is all inconvenient by bike to understanding distance travelled and safety at any time exactly.Especially need to be grasped the distance travelled situation for racing car and mountain bike with multiple speed changing function and long distance travel.

The purpose of this utility model provides a kind of bicycle running speed that is suitable for, and the bicycle taximeter that is complementary with the bicycle transmission.

The utility model is achieved in that the bicycle taximeter comprises meter, variator and flexible axle.Meter and present motorcycle can show distance travelled and gait of march with having the records of distance by the log epiphase together.Variator comprises driving gear and driven gear.Two gears are spiral gear.Driving gear is fixedly mounted on the backshaft skin in rear axle left side, and shell is provided with the circular hole that passes for rear axle.Shell is connected by the nut on the rear axle and rear axle and vehicle frame, and covers on the driving gear outside.The driving gear inboard is provided with dust cap.Driven gear is positioned at the driving gear below, is fixed in the housing and with driving gear by axle sleeve and flexible shaft end seat and meshes, and its output shaft forward.One end of flexible axle and the flexible shaft end on the driven gear output shaft join, and by flexible shaft end seat and nut location.Flexible shaft end on the other end of flexible axle and the meter joins.Meter is fixed on the handlebar by fixed mount.

When bicycle was advanced, driving gear and bicycle rear rotated synchronously, and drove the driven gear rotation by certain speed ratio.Driven gear drives by flexible axle and has the records of distance by the log, and only need overlook the mileage and the speed of a motor vehicle that can clearly read bicycle running in the time of by bike.

The utility model advantage is simple in structure, and cost is low, and is easy for installation, has the records of distance by the log accurately.

The electronic watch of packing in meter also can increase clocking capability.

Fig. 1 is the wiring layout that bicycle taximeter variator is loaded on rear axle axle skin;

Fig. 2 is the cut away left side view of Fig. 1;

Fig. 3 is the synoptic diagram that meter is installed on handlebar.

The utility model is described in further detail below in conjunction with accompanying drawing: the bicycle taximeter mainly is made up of meter, variator and flexible axle.The meter that the available present motorcycle of having the records of distance by the log is used belongs to known technology.Variator comprises that driving gear 2, driven gear 1, two gear are spiral gear.Driving gear 2 usefulness screws 3 are fixed on the backshaft skin 7 in rear axle left side.Shell 4 is enclosed within on the rear axle by the circular hole 16 at middle part, and with the fixed by nut on the rear axle 6.Shell 4 is sealed from the outside with driving gear 2, and the inboard of driving gear 2 is then sealed by dust cap 5.Driven gear 1 is positioned at the below and driving gear 2 engagements of driving gear 2.The output shaft of driven gear 1 is towards the place ahead of car.Be shaped on flexible shaft end 17 on the output shaft.Driven gear 1 is fixed in the shell 4 by axle sleeve 8 and flexible shaft end seat 9.Meter 11 is fixed on the middle part of handgrip 13 by fixed mount 14.One end and the meter of flexible axle 15 join, and the flexible shaft end 17 on the other end and driven gear 1 output shaft joins and located by flexible shaft end seat 9 and nut 10.For making things convenient for timing, can in meter 11, install electronic watch 12 additional.
