Abstract

<P>PROBLEM TO BE SOLVED: To solve the problems with conventional self-force driving bicycles wherein a self-force is not effectively used alternately and repeatedly since a self-load occurs around a crank pivot radially inward on the pedal side of a sprocket at a correlation ratio of the length of a crank to a counter electrode and a magnification occurs radially outward, the depression of a pedal is started when the sprocket is in the self-load area for pulling a chain, when the pulling of the chain reaches a magnification occurring area, the pedal reaches a depressing end point, and the start of one alternate rotation of the pedal crank is within the self-load area and the magnification occurring area is positioned after the completion of rotation. <P>SOLUTION: All functions from the occurrence of magnification to the pulling of the chain are formed in a crank arm and rod pulling type, a magnification route is shortened and the magnification is not lost. The flexibility of the rotation of the sprocket is maintained by using a pulling rod and a double bearing. The synchronization of rotation and a self-load occurring radially inward on the pedal side of the crank are cut off. A second magnification device is disposed in a sprocket body as a structure body. The sprocket itself performs the magnificatioin production and the magnified pulling simultaneously. Consequently, the magnification of self load and the magnified pulling of the chain can be performed without reducing the self-load. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention is intended to boost the self-rotation driving force of a bicycle or the like, and the first booster and the second booster are arranged on the base material of the sprocket, so that boosting production and boosting can be achieved. The present invention relates to an integrally configured rotary drive mechanism that performs conversion at the same time at sprocket poles and performs chain traction in a boost generation region.

  A conventional bicycle or the like has a transmission mechanism for increasing and decreasing speed (for example, see Patent Document 1). Although there is a document of the existing application of the boosting amplification generation mechanism, there is no implementation regarding the mechanism (see, for example, Patent Document 2).

  Hereinafter, the conventional speed change mechanism will be described with reference to FIG. 3. The axis of the electric actuator (27) is arranged along the diagonal of the parallelogram interlocking device, and the relative distance between the two diagonals of the parallelogram is changed. A gear shift device according to claim 1, having the characteristics.

The boost generated by using the distance comparison between the pedal and the boosting pole for crank rotation with the free rotating shaft 5 of the left and right cranks 6-A and 6-B as a supporting point, which will be described with reference to FIG. Different transmission forms on the left and right sides are transmitted to the second booster amplifying unit using one transmission path of the first booster full circumference transmission gear 9.

In the conventional speed increasing / decreasing device mechanism described above, a method of obtaining an increase in speed by applying a load to the power of turning the crank and a method of reducing the self load by reducing the speed are implemented.
There is a document 2 of a boosting amplification mechanism in the present application, but the weight and volume are excessive, and the gear transmission system makes the boost transmission path too long. There was a loss of boost between the continuous transmission of the gear and the gear meshing clearance, and there was a gear meshing noise with the weight volume exceeding the working range.

  In a conventional pedal crank / sprocket fixed combination drive, the pedal side inner radius and the counter outer radius at the center of the sprocket fulcrum shaft generate a boost in the outer radius of the sprocket by comparing the crank length with the length of the counter outer radius. However, self-loading occurs on the pedal side inner radius. The pedal crank depressing start position is the same when the sprocket starts in the self-loading range of chain traction and when the pedal reaches the end point of crossing and when the sprocket reaches the boost generation range, the same boost range is on the opposite side It is also the range of occurrence of self-load by hitting the pedal depression start position. Self-power is not effectively implemented during one rotation of the crank left and right alternately.

  To make the crank fulcrum shaft and the sprocket coaxial, individual balls and rollers cannot be rotated with the conventional bearing type. When the outer circumference and the inner circumference move in the opposite directions, ball rotation occurs and moves in the same direction, the ball does not rotate.

  The present invention changes the problem solving and the conventional function of such a conventional function, and does not reduce and reduce the load of the own power of the conventional self-driving function, but boosts and doubles the self-power. Achieved power amplification, and boosted amplification production by converting the existing booster length path transmission and boost loss, and the weight loss and boost transmission function of weight volume exceeding the scope of implementation. The purpose is to realize a mechanism that can perform the pole and chain pulling pole simultaneously as the same point of boost production and boost conversion.

  In order to achieve the above object, the present invention provides a first booster crankshaft disposed in a hanger rack as a device for isolating and separating a self-load region generated at the pedal-side inner radius of a sprocket of a conventional drive machine and a booster amplifying device. The double-sided needle bearing is used for the inner and outer circumferences, and the second magnifying device and the booster conversion device are movably arranged in the left and right sides of the sprocket as the base, and the first traction lot is connected. The installed sprocket body is installed and arranged.

  This is an integrated configuration in which left and right first booster cranks are fitted and arranged at both ends of the above-described device arranged on the existing first booster crankshaft.

  The operation of the first problem solving means is as follows. The first boost generated by alternately rotating the left and right first cranks is the first traction lot, and the second amplified boost produced by pulling the left and right second amplified crank arms formed on the sprocket is used as the sprocket. It is possible to perform boost production and boost conversion at the same connecting point.

  In addition, in the mechanism, the operation of the second problem solving means is such that the generation of the boost, the traction, and the boost conversion are instantaneously performed by the traction system, and in the traction system, the self-powered momentum and the boost that are consumed in the boost transmission path. There is no loss, no towing connection sound is generated, and it is about the meshing sound at the time of towing the chain, and the boosting effect is exerted reasonably by the two-stage integrated configuration by the first and second boosting amplification.

  As described above, the boost conversion type rotary drive machine of the present invention cuts and separates the self-load area generated at the pedal-side inner radius of the sprocket using a double-structure bearing as an interlocking insulator, and the entire space around the sprocket is empty. As a region, the boost conversion can be easily performed.

  By the two-stage traction system of the first booster and the second amplifier section, the boost amplification production and the conversion of the booster of the sprocket can be performed instantaneously, so that there is no functional resistance against self-power and no traction sound is generated.

  As the first and second amplification devices, the second booster crank arms arranged on both the left and right sides of the main sprocket are the simultaneous start-up of the booster and the booster conversion in the region where the chain is pulled. With the integrated mechanism that can be used, it is possible to provide a boost-amplification conversion type drive machine that is labor-saving and has a light weight.

  In addition, since each device is centrally arranged with the sprocket as the center of construction, the boost amplification production and the boost conversion can be completed at the same time, so the action sequence is short path, less device configuration prevents the loss of boost, weight volume The effect of reducing the reduction of gear noise is exhibited.
