Description

Transmission system buffer

The invention relates to a transmission system buffer, in particular to a buffer structure assembled on a wire group pulling line of a bicycle to make a shifting speed, so as to dial the action of the control handle, the excessive force is stored first, and the feedback can be quickly reached. It is the application creator that drives the transmission to change gears and protect the entire shifting system from excessive stress.

According to the bicycle, not only does not need to consume fuel, but also can achieve sports fitness, travel travel, augmentation, creation of the soul and the function of travel, riding bicycles will not have air pollution, has many advantages and benefits.

However, bicycle riding, in response to changes in terrain or speed, in addition to the general early traditional bicycle type, there are also more advanced variable speed bicycles, and the shifting system is mainly manual operation, but not everyone can respond to objective conditions. Such as road conditions, terrain, slope physical fitness and experience, etc., and can immediately respond to the best judgment and degenerate control.

The general mechanical cable shifting system is fixed to the vehicle body or the handlebar by a control handle for controlling and positioning the transmission, and the transmission moves the guide pulley and the guide plate between the teeth to execute the chain and the plurality of teeth. The running of the piece changes, causing the chain to be forcibly disengaged between the teeth to continue to run on the teeth in the other track. So the earliest transmission was called the derailer, mainly even if the chain was disengaged. Working on a different tooth with a different number of teeth, the difference in the gear ratio is achieved, that is, the shifting, which is also commonly referred to as shifting.

However, the change between the chain, the toothed piece and the pulley guide is forced to disengage; in the process, friction will be generated and the part of the pedaling power will be degraded. Therefore, if more gears are to be changed at a time, it is necessary to press harder. The control handle, known as the change lever, enables it to achieve multiple shifts. If you want to change the gear position more quickly, you must press the control handle more hard. This will increase the friction and create resistance, while the rider It is also necessary to withstand these frictional resistances.

Although, every knight who uses the transmission wants to be able to change the gear ratio more quickly and agilely, the normal over-forced change chain will run between the teeth, which will reduce the change. The service life of the entire shifting system, line set, transmission, toothed to chain, etc.

Further, a threaded section (215) is disposed on the wall surface of the through hole (212) of the outer tubular body (21), the threaded section (215) correspondingly and screwed with an adjusting member (24), and the adjusting member (24) comprises an outer casing (241), an elastic body (242) and an adjusting bolt (243), wherein the elastic body (242) is placed in the outer casing (241) and the adjusting bolt (243) passes through the elastic body (242) and the outer casing ( 241), and the end surface of the outer casing (241) is provided with a tooth portion (244), and the end surface of the corresponding tubular body (21) is also provided with intermeshing tooth portions (20), and the adjusting bolt (243) is provided at the center. The through hole (240) of the supply group cable (1) is inserted and adjusted The whole bolt (243) corresponds to the threaded section (215) of the outer tubular body (21) (as shown in the sixth figure).

Referring to the first to tenth drawings, first, the wire set cable (1) includes an inner wire (11) and an outer pipe (12). When the present invention is assembled with an adjusting member (24), the embodiment is described as When assembled and used, the actuating member (23), the elastic member (22) and the adjusting bolt (243) of the adjusting member (24) are respectively corresponding to the inner wire (11); and the actuating member (23) is placed. In the outer tube body (21), after the O-ring pad (233) is disposed on the outer ring wall of the actuating member (23), the actuating member (23) is abutted against the annulus (231) against the outer tube. The fixing buckle (214) at the wall of the second end of the body (21), and then the elastic member (22) is correspondingly disposed in the hollow chamber (211) of the outer tubular body (21), and the adjusting member (24) is adjusted The bolt (243) is assembled with the threaded section (215) of the outer tubular body (21) to complete the buffer (2), and then the buffer (2) is correspondingly disposed on the bicycle frame (3) or the wire harness. (1) Or the transmission (4) or the control handle (41) (as shown in Figures 1 to 4).

Then, according to the general transmission (4) (shifting system), as in the prior art, in order to control the transmission (4) with the control handle (41), the running of the chain (5) and the plurality of teeth (51) is performed, so that the guide wheels ( 42) and the guide plate (43) moves between the teeth (51), so that the chain (5) is forcibly disengaged between the teeth (51) to continue to run on the teeth (51) in the other track; When adding the damper (2) of the present invention to the bicycle, please refer to the sixth to eighth diagrams together. When the self-actuating shifting is performed, the shifting control handle (41) at the control handle is controlled by the handle (41). Linking the wire set (1) When the inner wire (11) and the outer pipe (12) of the wire are pulled, the outer pipe (21) is restrained by the frame (3) and the terminal (31). The limit position enables the actuating member (23) to reversely compress the elastic member (22), so that the force of the force is pushed to push the elastic member (22) when the shifting is performed, so that the elastic member (22) has a compressive internal force. After the positioning is pressed, the transmission (4) is shifted by the restoring force compressed by the elastic member (22).

If the rider dials multiple gears at a time (for example, third gear), more force is generated to compress the elastic member (22), and excessive force is temporarily stored in the elastic member through the wire set cable (1). 22), and when the control handle (41) is positioned by the dial, the compressive force of the elastic member (22) is automatically reset to release the elastic force, pushing the transmission (4), the chain (5) and the tooth piece (51) and The guide wheels (42) cooperate with each other to achieve a shifting action.

In addition, the main components of the present invention are an outer tubular body (21), an actuating member (23), an elastic member (22), and a fixed retaining ring (214) which cooperate with each other to actuate the main force due to the compressive force and the stroke; The wire group tensioning mode and the shifting system originally do not have a wire group tension adjusting device, thereby increasing the outer pipe thread segment and the shifting system buffer of the adjusting member.

Next, as shown in the ninth to tenth drawings, the adjusting member (24) includes an outer body (241), an elastic body (242) and an adjusting bolt (243) for placing the elastic body (242). The outer casing (241) is inserted into the outer casing (241), and the adjusting bolt (243) passes through the elastic body (242) and the outer casing (241), and the outer surface of the outer casing (241) is provided with a tooth portion (244) corresponding to the outer tubular body (21). The end face is also provided with intermeshing teeth (20); the cable set (1) of the transmission (4), the adjusting bolt (243) can be screwed into the outer pipe body (21) by the adjusting member (24) The depth of the threaded section (215) adjusts the positioning of the transmission (4), that is, the tension of the wire harness (1).

However, when the wire harness (1) is at the maximum tension, the inner wire (11) of the cable is not extended, and the outer tube (12) cannot be recompressed, but the frame (3) is riding. There will be some stress deformation and multi-directional torsion, tension and compression factors. Therefore, when the frame (3) is under stress, the wire harness (1) is fixed to the terminal (31) of the frame (3); and the above factors may be used to pull the wire (1) And the fixed terminal (31) and all associated shifting parts generate excessive pulling force, which can be absorbed by the elastic member (22); let these related zeros The piece no longer has excessive pull. The above description can also be applied to the front derailleur (6) in the same way, and the same effect can be achieved.

From the above structural arrangement, it can be seen that the buffer of the present invention corresponds to the difference between the number of plates and the number of segments of the shifting system and the required buffering force (stroke) required to set the compression starting action of the elastic member (22). The force until the elastic member (22) stops compressing is between 3kg and 30kg; and when the elastic member (22) is installed in the outer tubular body (21), the outer tubular body (21) and the actuating member are 23) Limiting and micro-compression, so that the force of the compression starting action of the elastic member (22) at this time is between 4 kg and 30 kg for the action of the actuating member (23) to compress the elastic member (22) to stop the compression.

Further, the elastic member (22) in the independent state or the elastic member (22) in the hollow chamber (211) of the outer tubular body (21) has a compression stroke of 1 m/m to 20 m/m.

However, the above-described embodiments or drawings are not intended to limit the scope of the invention, and the scope of the invention is to be construed as being limited by the scope of the invention.

As can be seen from the above structures and embodiments, the present invention has the following advantages:

1. The damper of the transmission system of the present invention, when the shifting force is repeated in the shifting process, the excessive pressing force is the compressive force of the elastic member, and the compressive force is temporarily stored in the buffer, and will naturally recover; Instantly converts to thrust, allowing the returning thrust to push the transmission to quickly shift gears while achieving the ability to protect all parts of the entire shifting system.

2. The damper of the transmission system of the present invention allows the original excessive plucking force to be temporarily stored and then operated by the buffer. When the stroke and the gear position are too large, the shifting system cannot be stopped in time, and the dialing is performed. Can't press it; the excessive friction generated by dialing will not happen again. The force applied to the entire system is completely controlled so as not to be too large, and the automatic automatic synchronous accumulation and temporary operation can make the shifting and shifting process faster.

In summary, the embodiments of the present invention can achieve the expected use efficiency, and the specific structure disclosed therein has not been seen in similar products, nor has it been disclosed before the application, and has completely complied with the provisions of the Patent Law. And the request, the application for the invention of a patent in accordance with the law, please forgive the review, and grant the patent, it is really sensible.
