Abstract
The utility model provides a commutator for bicycles for the technical field of bicycle fitting. The utility model is mainly characterized in that by the installation of two cylinder-shaped flywheels through the turning function of an angular wheel and the installation of a unidirectional driving device, a wheel disc enables the bicycle to move forward when the wheel disc turns forward or backward. People can make the bicycle move forward by forward pedaling or backward pedaling; the utility model avoids the only way of pedaling forward for easy causing of mechanical damage of the human body; by altering the strength using direction, more muscles can exercise thoroughly without being damaged; the utility model is beneficial to exercise body and alleviate fatigue.
Description
The utility model belongs to the bicycle accessories technical field, is a kind of Commutator for bicycle.
The present bicycle that uses, foot-operated toe clip runner disc rotates, and drives the flywheel with one-way driving mechanism through chain, drive wheel again bicycle is advanced, but wheel disc and pedal is when rotating in the opposite direction, and bicycle can not advance.The purpose of this utility model is a kind of Commutator for bicycle of design, makes wheel disc and pedal when different directions rotates, and bicycle is advanced.
The technical scheme that the utility model is taked is design one "+" font axletree, a pair of is axletree, another is to being reversing shaft, the commutation finishing bevel gear cuter is set on reversing shaft, on axletree, be provided with respectively drive finishing bevel gear cuter and with the engagement of commutation finishing bevel gear cuter, outside two driving finishing bevel gear cuters, the tubular flywheel is set respectively, wherein a tubular flywheel adopts one-way driving mechanism to be connected with the driving finishing bevel gear cuter, another drives finishing bevel gear cuter and the tubular flywheel is fastenedly connected, drive setting and wheel bonded assembly one-way driving mechanism on the finishing bevel gear cuter at it, thereby constitute the utility model Commutator for bicycle.
The utility model is when the moving band of chain wherein during a tubular flywheel, as with drive the tubular flywheel that the awl tooth is fastenedly connected, then tubular flywheel linkage driving finishing bevel gear cuter drives finishing bevel gear cuter by one-way driving mechanism, drives wheel and advances; When the chain reverse drive, because the effect of one-way driving mechanism, wheel can not advance, and is identical with existing bicycle operation, when chain oppositely drives another tubular flywheel, another tubular flywheel drives by one-way driving mechanism and drives the awl tooth and drive last driving finishing bevel gear cuter by the commutation finishing bevel gear cuter, the drive wheel advances, when chain on this tubular flywheel during the forward transmission, because the effect of one-way driving mechanism, wheel can not advance equally, and is just in time opposite with the wheel disc operation with existing bicycle pedal; Therefore by this Commutator for bicycle, the cyclist can select bicycle is advanced, and has avoided existing bicycle to exert oneself forward, easily causes the human body mechanical injuries, by changing power thrusts, change the human body position of exerting oneself, make relevant muscle can access sufficient movement and non-easy damaged is of value to and takes exercises, slow down fatigue, to firmly, change the fixed pattern that forward direction is exerted oneself by the back, helped to take exercise people's reverse thinking; This Commutator for bicycle has kept the function of existing bicycle, therefore, compares with prior art and to have significant advantage.
Reach example in conjunction with the accompanying drawings and further introduce the utility model architectural feature;
Accompanying drawing is represented structural representation of the present utility model;
Referring to accompanying drawing, the utility model comprises "+" font axletree, wherein a pair of is reversing shaft, dress adopts pin 2 lockings with commutation finishing bevel gear cuter 7 on it, another is to being axletree, on the single wheel axle, be provided with forward finishing bevel gear cuter 5, forward finishing bevel gear cuter 5 coaxial height are provided with the energy one-way driving mechanism, not shown in the figures, forward finishing bevel gear cuter 5 is outer to be provided with forward direction tubular flywheel 3 and to be fastenedly connected with it by screw 4, on the opposite side axletree, be provided with the back to driving finishing bevel gear cuter 8, its outer back that is provided with is to tubular flywheel 9, and connect by one-way driving mechanism, the back is connected with axletree by antifriction-bearing box 1 to driving finishing bevel gear cuter 8, one-way driving mechanism on the forward finishing bevel gear cuter 5 is connected with wheel, and mesh with commutation finishing bevel gear cuter 7 respectively to driving finishing bevel gear cuter 8 forward finishing bevel gear cuter 5 and back, makes chain preceding by dialling the chain device, the back is to tubular flywheel 3,9 conversions.
Claims (1)
1, a kind of Commutator for bicycle, it is characterized in that having one "+" word axle, on an axis of symmetry, be provided with the commutation finishing bevel gear cuter, on another axis of symmetry, be respectively equipped with the driving finishing bevel gear cuter, the commutation finishing bevel gear cuter is meshing with each other with the driving finishing bevel gear cuter, the driving finishing bevel gear cuter of one side is provided with the tubular flywheel, and is fastenedly connected with driving finishing bevel gear cuter, drives finishing bevel gear cuter and is provided with the one-way driving mechanism that connects wheel; Also be provided with the tubular flywheel on the driving finishing bevel gear cuter of opposite side, the tubular flywheel adopts unidirectional being in transmission connection with driving finishing bevel gear cuter, and it drives finishing bevel gear cuter and is connected with "+" word axle by bearing.
