Why is the bicycle flywheel designed on the right side and not on the left???

Or because of the habit problem, the vast majority of people are used to getting on the cart and pushing the cart on the left side, and the design on the right side can avoid hitting the sprocket when getting on the cart and pushing the cart.

The flywheel on the right is designed from the habit of most people, and people generally get on the bus from the left.

The average person is dexterous with his right hand, so he uses his right hand to dial 6 9 speed finger dial, and left hand to dial 3 speed, so the flywheel is on the right side.

How to install 2 flywheels on the right side of the bicycle Hello dear, because the width of the thread buckle on the outside of the rear axle hub is not enough, it is not possible to install two flywheels, if you must install two flywheels on the rear wheel, you can install the flywheel on the left one to fix the flywheel, until it is completely occlusive with the flywheel piece. Then the function of the flywheel fixing tool is to prevent the flywheel or the tower base from rotating when the flywheel cover is loosened. At this time, the flywheel cover is loosened, and then the wheel is placed on the table, and the flywheel is adjusted to the state of facing the lead beam reed, and then it is necessary to use a large movable wrench, counterclockwise twist the flywheel cover tool, and also apply the force to the flywheel fixed wrench in reverse.

Then apply some pressure to the flywheel retention wrench to prevent the chain from falling off the flywheel. So if there is still a slippage after doing this, it means that the cassette flywheel has been worn. After that, try it again with a larger flywheel.

If you use a quick-release lever, after the flywheel cover is unscrewed, you need to remove the quick-release lever before you can do follow-up work.

Summary. Because the rear wheel is on the left side of the car (there is the drivetrain and transmission on the right), the front wheel is habitually placed on the left side, so you can release it as long as you stand on the side of the car. Like Shimano, the front wheel is usually parallel to the fork, that is, upward, and the rear wheel is usually placed between the rear and bottom forks.

Like Quantum, Jiuyu and other straight club heads, the front wheel is generally upward, and the rear wheel is also placed between the rear upper and lower forks or also upward. This question depends on what kind of fork or frame it is, in short, it follows two principles: one is easy to disassemble and easy to use; Second, it is not easy to be hung by foreign objects.

Hello. To the left.

Because the rear wheel is on the left side of the car (there is the drivetrain and transmission on the right), the front wheel is habitually placed on the left side, so you can release it as long as you stand on the side of the car. The bend head of the Shimano wheel is usually parallel to the fork at the front wheel, and the chant is upward, and the rear wheel is usually placed between the upper and lower forks. Like Quantum, Jiuyu and other straight club heads, the front wheel is generally upward, and the rear wheel is also placed between the rear upper and lower forks or also upward.

This question depends on what kind of fork or frame it is, in short, it follows two principles: one is easy to disassemble and easy to use; The second is that it is not easy to be hung up by laughing foreign objects.

The flywheel is fixed at the right end of the rear axle with internal thread screwing, maintains the same plane with the sprocket, and is connected with the sprocket through the chain to form the driving system of the bicycle. In terms of structure, it can be divided into two categories: single-stage flywheel and multi-stage flywheel. The single-stage flywheel, also known as the single-chain wheel flywheel, is mainly composed of parts, such as a jacket, a flat block and a core, a jack, a jack spring, a washer, a wire block, and a few steel balls.

The working principle of the single-stage flywheel of the bicycle: when the pedal is pedaled forward, the chain drives the flywheel to rotate forward, and then the flywheel internal tooth and the jack are contained, and the rotating force of the flywheel is transmitted to the core through the jack, and the core drives the rear axle and the rear wheel to rotate, and the bicycle moves forward. When the pedal is stopped, the chain and the jacket do not rotate, but the rear wheel still drives the core and the jack to rotate forward under the action of inertia, and the flywheel inner tooth produces relative sliding, thereby compressing the core into the notch of the core, and the jack compresses the jack spring.

When the jack tooth top slides to the top of the flywheel's inner teeth, the jack spring is compressed the most, and then slides forward a little, and the jack is bounced to the tooth root by the jack spring, making a "click" sound. The core rotated faster, and the jacks quickly slid on the inner teeth of each flywheel, making a "click" sound. When the pedal is reversed, the jacket rotates in reverse, which will accelerate the sliding of the jack, making the "click" sound more urgent.

The multi-stage cassette is an important part of the bicycle transmission. The multi-stage flywheel is based on the single-stage flywheel, adding several flywheel pieces, combined with the sprocket on the central axle, to form a variety of different transfer ratios, thus changing the speed of the bicycle. ：

The working principle of its single-stage flywheel: when the pedal is stepped forward, the chain drives the flywheel to rotate forward, then the flywheel internal tooth and the jack are contained, and the rotating force of the flywheel is transmitted to the core through the jack, and the core drives the rear axle and the rear wheel to rotate, and the bicycle moves forward. When the pedal is stopped, the chain and the jacket do not rotate, but the rear wheel still drives the core and the jack to rotate forward under the action of inertia, and the flywheel inner tooth produces relative sliding, thereby compressing the core into the notch of the core, and the jack compresses the jack spring.

Some of the skin, our general flywheel is installed on the right, that is, the ordinary flywheel, and there is a kind of flywheel is installed on the left, closed bi is generally used on the left side of the tandem bicycle, or electric vehicle modification, or mechanical equipment for combustion speed.

If both sides of the flywheel are flat, the side of the wheel is usually facing outward, and if there are 2 or more grooves on one side, the side with grooves is outward.

The anti-tooth flywheel needs to be bought on the * treasure, and it is rarely used offline, and it is not easy to buy.

The flywheel is a large cast iron inertia disc, which stores energy to supply the demand for non-work strokes, drives the entire cranklink structure over the upper and lower dead centers, and ensures the engine crankshaft.

The inertia of rotation The uniformity of rotation and the uniformity of output torque are aided by the inertial force of rotation of the flywheel itself.

Helps overcome compressive resistance in the cylinder during start-up and maintains engine operation in the event of short-term overloads.

1. Function: A part of the function input into the crankshaft in the work stroke is stored to overcome the resistance in other strokes and drive the crank connecting rod mechanism to attack the land.

Crossing the top and bottom dead center ensures that the angular velocity of rotation and output torque of the crankshaft are as uniform as possible, and makes it possible for the engine to overcome short-term overloads while transmitting the power of the engine to the clutch.

2. Common injuries of flywheels: Wear of flywheel teeth, broken flywheel teeth, grooves, burning scars, and cracks on the surface of flywheels.

3. Overhaul of flywheel gear ring.

If there is damage to individual teeth and wear on one side of the ring gear, the ring gear can be chamfered at the other end of the gear tooth to flange it. If it exceeds 30% of the tooth length or more than four teeth are damaged consecutively, it should be replaced.

4. Replacement of the flywheel gear ring: the new gear ring and the flywheel outer circle are generally overshot and the surplus is generally millimeters, and the gear ring should be heated to 350 degrees during installation, and the gear ring should be pressed to the stop while it is hot.

There are positive and negative, and the reverse cannot be installed.

I don't know what the landlord's 27-speed means. Is it 3 in the front and 9 in the back?

According to the description of the landlord, the sound is caused by the front dial scraping chain, and in this case, the limit screws of the dial need to be adjusted (there are two envy exposed screws on the dial, usually Phillips screws, and the letters h and L are noted next to it). Here's how to adjust it:

1. The landlord first dials the front to the most ** when riding, and the back dials to the minimum disc to ride, observe, if the chain grinds to the outside of the dial, loosen the H screw, if it is grinding the inside, you need to tighten the H screw slightly. The specific tightness should be tested while adjusting.

2. Adjust the front to the smallest plate, and the back to the most, if you rub the chain, the dial rubs the inside of the "L" to relax, and the outside is tightened. Try as you adjust.

and 2 repeated test adjustments until the equilibrium point. If it is not perfect to achieve both up and down at the same time, either the height of the dial is not installed correctly, or the crankset and the dial are not compatible.

4. There is no sound when you step on it, and there will be a sound of rubbing the chain when you step on it: Congratulations to the landlord, the foot strength has exceeded the intensity of the use of this crankset, and the crankset can be upgraded or the whole vehicle can be replaced!

The easiest way to do this is to take it to the car shop and have the mechanic adjust it. Generally, a relatively large bicycle shop, with its own simple and fixed group of bicycle friends, will help people transfer cars for free. ~

Thank you very much!

Look at the rotation, the chain scrapes the front dial to measure the inside or the outside, and the rear dial hangs to the smallest tooth when the outside of the grinding front dial needs to be tightened (counterclockwise state Qi rotates the front dial adjustment screw, adjusted to half a circle or a quarter of a circle as a unit until it is not grinding), and the rear Qi is adjusted to the maximum tooth If the grinding is inside, then adjust the fine-tuning screw clockwise.

Upstairs is the solution, adjust the limit screws of the front dial, scatter and rear dial also have a certain relationship, but the spring excavation to find a lot of tutorials**, but it is still recommended to go to the car shop to let the technician adjust. Thank you and thank you!
