Abstract
The utility model relates to a bidirectional pedal of a bicycle, which is composed of a gear disk, an outer shell, a planetary gear, a special bearing, etc. When the bicycle is forwards pedaled, dynamic force is transported to an outer ratchet pawl through a chain wheel and the gear disk, causing that the inner ratchet pawl shifts the outer shell; the outer shell can drive a back shaft sleeve and a back wheel to forwards rotate. When the bicycle is backwards pedaled, the dynamic force is transported to an inner ratchet pawl through the chain wheel, the gear disk, the planetary gear and the special bearing, causing that the inner ratchet pawl shifts the outer shell; the outer shell can likewise drive the back shaft sleeve and the back wheel to forwards rotate. When the utility model is arranged on a back shaft of the bicycle, the bicycle has the functions that the bicycle can advance when forwards and backwards pedaled; the pedaling direction is changed when in ride, so that the fatigue is reduced, and the utility model is good for body-building; the utility model can be widely used for the structure improvement of an existing bicycle.
Description
The utility model relates to a kind of bicycle drive that can forward and reverse treadmill.
The applicant once on October 13rd, 94 application and Granted publication " the two-way foot pedal apparatus of bicycle ", application number: 94243136.7, there is complex structure in the technical scheme of this patent, difficulty of processing is big, the more high shortcoming of cost, for improving above-mentioned shortcoming, the special the technical solution of the utility model that proposes.
The purpose of this utility model provides a kind of simple in structure, handling ease, the two-way foot pedal apparatus of lower-cost improved bicycle.
The purpose of this utility model is achieved in that it comprises shelves dish, shelves dish steel ball, shell, and it is characterized in that: the outer ratchet that is equipped with on the shelves dish outer ring matches with the ratchet of shell, and the tooth of inner ring is meshed with planetary small tooth plate tooth; The oiling stopple is arranged on the shell, and shell is captiveed joint with backshaft skin; Special bearing is made up of flanged outer ring, steel ball, inner ring, and the outside, outer ring is equipped with interior ratchet and is matched with the ratchet of shell, and there is tooth the outer ring flange inboard and is meshed with planetary wheel large fluted disc tooth, and inner ring is fixed on the rear axle by key; Planetary wheel is installed on the special bearing inner ring by gear wheel shaft.
The purpose of this utility model can also following manner realizes: shell and backshaft skin are captiveed joint by screw thread or key or radial screw mode.
The utlity model has simple in structure, handling ease, cost is lower, the advantage that is easy to promote provides a kind of desirable device to utilizing bicycle to carry out body building.
Elaborate below in conjunction with accompanying drawing:
Accompanying drawing is the utility model structural representation.
The utility model can be installed on the rear axle of bicycle, and between backshaft skin 17 and sprocket wheel 3, rear axle 1 is an extended type among the figure, and axle shelves 2, sprocket wheel 3, axle shelves steel ball 4 and backshaft skin 17 are the existing part of bicycle.The utility model is mainly by shelves dish 5, and shell 14, special bearing and planetary wheel 8 are formed.Shelves dish 5 is connected with sprocket wheel 3, and shelves coil and on 5 outer rings outer ratchet 7 are housed and match with the ratchet of shell 14.Tooth on shelves dish 5 inner rings is meshed with the small tooth plate tooth of planetary wheel 8.Shelves dish 5 outer rims that are positioned at shelves dish steel ball 6 assembling that matches with shell 14.Have oil hole on the shell 14 and stop up by stopple 10.Shell 14 is captiveed joint with backshaft skin 17, and connection mode can be modes such as screw thread, key or radial screw, is illustrated as to be threaded.Special bearing is made up of flanged outer ring 9, steel ball 12, inner ring 15,9 outsides, outer ring are equipped with interior ratchet 11 and are matched with the ratchet of shell 14, outer ring 9 flange inner have tooth and are meshed with the large fluted disc tooth of planetary wheel 8, and inner ring 15 is fixed on the rear axle 1 by key 16.Planetary wheel 8 is installed on the special bearing inner ring 15 by gear wheel shaft 13.
Working process: shown position is to see the utility model installation site backward from bicycle handle bar.Forward is ridden when advancing, and sprocket wheel 3, shelves dish 5 rotate forward, drives the rotation forward together of shells 14, backshaft skin 17 by outer ratchet 7, and wheel advances.This kind situation, planetary wheel 8 makes the planetary wheel backwards rotation by the engagement that shelves coil 5 internal ring gears and its small tooth plate tooth, thereby drives also backwards rotation of special bearing outer ring 9, and at this moment interior ratchet 11 produces slide relative with shell 14.
When oppositely foot-operated, shelves dish 5 rotates backward and produces slide relative with shell 14, outer ratchet 7.Shelves dish 5 rotates forward by the moving planetary wheel of the cingulum on its inner ring, and by special bearing outer ring 9, interior ratchet 11 drives shell 14 and backshaft skin 17 rotates forward, and bicycle is advanced forward.
