Abstract
The utility model discloses a wheel transmission gear for a bicycle or a tricycle, which comprises wheels, a frame, pedals, a crank and a planetary gear drive mechanism. A center gear tooth of the drive mechanism is connected with a wheel axis via a ratchet wheel unidirectional clutch, a planetary gear is movably connected with the crank, and a gear ring is fixed on the frame; the planetary gear is used as a driving gear for driving the center gear tooth to quickly rotate, so the wheels are driven and operated. Because the utility model uses the advanced planetary gear drive mechanism and has a good match with the wheels, the utility model has the advantages of high efficiency, small size, long service life and easy maintenance.
Description
The utility model relates to a kind of wheel driver, is widely used in bicycle or three-wheel vehicle.
Application number is 93201375.9 " gear driving bicycle ", and its running part is to adopt the fixed axis gear transmission, and big, the inefficient shortcoming of volume has been compared in this transmission with epicyclic gear transmission.
The purpose of this utility model provides a kind of wheel driver, solves the problem that existing bicycle efficiency is low, the life-span is short.
Technical solution of the present utility model is as follows in conjunction with the accompanying drawings:
A kind of wheel driver comprises wheel, vehicle frame, pedal, crank, crank shaft, reaches planetary transmission, wherein comprises gear ring, planet tooth, centre tooth again.The axle of wheel is a hollow shaft, be enclosed within on the crank shaft, the crank shaft two ends are connected with crank and pedal, vehicle frame is movably installed in the axletree two ends, gear system is in a side of wheel, it is characterized by: the centre tooth of planetary transmission is connected with axletree by ratchet one-way clutch, and the planet tooth is movably connected on the crank, and gear ring is fixed on the vehicle frame.Planet number of teeth amount be 1,2,3 can, require crank shape can flexibly connect the planet tooth in the relevant position.Motion principle is: planetary wheel drives centre tooth and wheel accelerated service for initiatively, and free-wheel clutch separately makes the flexible safety of riding during the wheel inertia rotation.
Embodiment of the present utility model is identical with technical solution.
Owing to adopted advanced Planetary Gear Transmission, and fine with wheel Cooperation, so the standby volume of this driving implement is little, efficient is high, the life-span is long, The advantage of easy care.
Accompanying drawing is the actuating device sketch, and label is respectively (1) wheel (2) vehicle frame (3) gear ring (4) planet tooth (5) centre tooth (6) ratchet one-way clutch (7) crank shaft (8) axletree (9) crank (10) pedal.
