Abstract

The present invention is the application of "Dorae chain gear using the principle of Dorae" Application No .: 10-2009-0050299 by applying the above invention to the bicycle to the hunger shift immediately and instantaneously in the hills flat, etc. It's about the transmission.

According to the present invention, the two-speed type that uses two chains is attached to the left and right side of the bicycle, which can be steeply climbed. Equipped with an adhesive transmission to achieve.

Description

Pair Feeding Instantaneous Adhesion Gearbox Bicycle {omitted}

The present invention relates to a shifting device that separates low-speed and high-speed beams separately using a paired chain so as to immediately shift in any situation. Installed on the right side.

The reason is that when I apply for the application number: 10-2009-0050299, I don't need about 52 gears of all the gears.

Therefore, low speed and high speed two stages are less powerful and enjoyable riding than now.

The low-speed and high-speed applications are designed to be pulled and attached in the form of a clutch, so that the high-speed gear falls automatically when going to low speed, and the low-speed gear falls automatically when going to high speed.

There is no clutch-type instantaneous adhesive in the prior art and there is a "two-chain-drive bike," 10-2002-0044779, but this was only a way to regularly exercise both feet.

In order to shift gears currently used, the gear shift is only possible when the bicycle is moving.

The bi-directional manipulator can be used to shift gears by slightly turning either of the handlebars on either side of the bike.Turn the knobs on either side to turn the stopbo-turn [5] to the high-speed position, and the springs connected to the cable. In this case, the integrated pilot is shifted to the high-speed gear from the moment when it is integrated by inserting the protruding protrusion inserted when the pilot-side is bonded to the hole that is inserted when the high-speed gear is bonded along the both gears. Bi-directional instantaneous self-adhesive transmission of the bicycle, characterized by shifting the high gear and the low gear while going back and forth.

Since the hunger shift is instantaneous, it is possible to run freely on any alleys and use the low and high speed gears that can steep up the slope so that it can run freely anywhere. It is designed to enable long distance operation.

Referring to the present invention with reference to the accompanying drawings as follows.

[Fig. 1] shows the pedal shaft [30] on the front road with a double chain chain installed on the bicycle. A separate drive with two chains wound on the right side is installed, and an instantaneous self-adhesive transmission is installed in the middle of the low gear [2] and the high gear [1] in both pedal shafts [30]. Either side of [4] is used so that low speed gear [2] and high speed gear [1] can be shifted.

[Fig. 2] of the basic principle of the double-bulk chain is a simple description of the application of "Dorae chain gear using the dorae principle." It is the principle that the weight of the bicycle can be divided and rotated lightly with the roadway type chain gear [23] installed.

As shown in [Fig. 3], when stronger force is required, an additional transmission gear [31] [32] and a roadway chain gear [25] for subdividing the weight are additionally installed. It is installed equally on the left and right sides of the bicycle by installing them in pairs to rotate.

Here, the role of the integral transmission gears [31] and [32] can be freely changed at high speed or low speed depending on the ratio of gears, and when one or more integral chain gears are desired, more power is required. This can be used by connecting [32] and road crane chain gears [25].

In this way, the weight of the road chain chains [23] and [25] can be divided and returned on the flat and slope roads.

[Fig. 4] is a instantaneous adhesive transmission in the middle of the perspective view of a perspective view of the invention in which the same invention is installed on the left and right sides of the pedal shaft [30] which is the triangular support [40] of the bicycle body in the middle of both pedal shafts [30]. Assembling from the bottom of the support [40], insert the pilot key [10] into the groove [13] into which the pilot key is inserted, and attach the pilot [11] to the engagement gear [41] of the pedal shaft triangular support [40]. ], Then the low-speed chain gear [2] is inserted, and the protruding protrusions [16] inserted when bonding are inserted into the holes [17] inserted when bonding, and the low-speed gear [2] can be detached and attached freely. It is. Insert pedal shaft [30] here and tighten the nut [48] to finish.

Assembling the upper side on the opposite side inserts the pilot key [10] into the groove [13] into which the pilot key is inserted and the pilot [12] into the engagement gear [41] and into the lower pilot connection [10-1]. It is a method of shifting between high speed gear [1] side and low speed gear [2] side by shifting it by fixing it with screws [10-2].

Continue to connect the high-speed gears [1] to the protruding protrusions [14] of the control tube [12] and the holes [15] to be inserted when they are glued to each other to achieve gear shifting. -Tit [49] to finish.

Looking at [figure 5], which shows the finished section again, the use of the adhesive transmission is explained. Pull and release the cable [18] so as to shift even if only one of the left and right handles is moved. It becomes shift.

To the right handle [3], the stop button turn [5] is widely used in the market. It is used to fix the low speed and the high speed. In Figure 5, the stop bounce-turn [5] is in the low-speed position, so that the adhesive transmission [12] and the high-speed chain gear [1] are separated by a manipulator [10] connected by a cable [18]. Appearance.

Therefore, at this time, turning the pedal shaft [30] will only rotate the low speed gear [2].

[Figure 6] shows that when the stop button turn [5] is moved to the high speed by turning the knob [3], the cable [18] is loosened, the spring [19] is extended and the integrated pilot [11] [12] is pushed. While the low speed gear [2] is naturally pushed out with the adhesive transmission, the high speed driving is performed from the moment when it is combined with the projection [14] inserted when the high speed gear [1] is inserted.

Therefore, only high speed gear [1] will return at this time.

In order to deliver the above combination to the rear wheel, as shown in [Fig. 3], a set connecting the chain [50] in pairs to the back [20] is installed on the left and right sides of the high speed gear [1] and the same. Each low gear [2] consists of a set.

Claims

Double-Earth Momentary Adhesive Gearbox Bike. To ...

Enabling the two-way manipulator to shift gears on either side of the handlebars on the bike and turning the handle to turn the stop bounce from low speed to high speed increases the springs connected to the cable, allowing the integrated manipulator to engage both gears. According to this, the high speed gear is shifted to the high speed gear from the moment when it is integrated, and the protruding protrusion inserted when the pilot side is attached is inserted into the hole inserted when the high speed gear is bonded. A pair of full-time momentary adhesive transmission bike, characterized in that.

The method of claim 1.

By making large and small high speed gears and low speed gears, the speed and force can be adjusted to connect a set-set of integrated gears [31] [32] and chain gears [25] which can rotate stronger and faster than the current bicycle. How to.
