The difference between the three types of motorcycle transmission

Do you see a lot of motorcycles parked on the square with terrazzo rustic tiles ? Are you the owner of one of them? Do you know that the types include motorcycle transmission shaft drive, chain drive and belt drive? Why do different motorcycles use different transmission methods? What is the difference between them? You can get answers to these questions in this article.

 

 

The difference between the three types of motorcycle transmission

 

The drive shaft is an important part of the transmission of power in the automobile driveline. Its function is to transmit the power of the engine to the wheels together with the gearbox and drive axle, so that the automobile generates driving force. Under the night light of OPGW 36, the drive shaft ensures that you can ride safely at night to reach the coffee temper distributor shop.

 

Shaft drive

Since the direction of rotation of the shaft is perpendicular to the forward direction of the car, lateral torsion will appear when rotating, causing the car to tilt in the opposite direction of the shaft rotation. The higher the speed, the greater the force. Therefore, shaft transmission is not suitable for high-speed engines, and high-speed racing cars basically do not use shaft transmission.

The direction of rotation of the chain and the forward direction of the car are the same, and the torque generated only raises the front of the car, which has little effect on high-speed driving.

 

The shaft transmission is characterized by durability, high manufacturing cost, high material requirements, and difficult processing.

 

The chain drive is characterized by low cost, simple maintenance and not durable.

Many people would think that the shaft drive of motorcycles was developed by BMW in 1923. In fact, in 1901, Belgium's FN launched the 133cc single-cylinder motorcycle for the first time, and the following year FN launched the first FN300 motorcycle with shaft drive.

 

Since 1901, shaft drive has become one of the most popular transmission methods in China due to its smooth power transmission and long maintenance cycle and life.

The biggest advantage of the shaft drive is that it will not be stretched and the wheel track needs to be adjusted, no oil pollution can basically be maintenance-free, and the power loss is small and the drive efficiency is high. However, the shock absorption effect of the chain is not good, and the vibration of the body will be directly transmitted to the rider.

 

When the throttle is increased, a torque phenomenon will be generated in the rear part (torque reaction phenomenon-the body will fall in the opposite direction of the shaft drive rotation during rapid acceleration or rapid deceleration), which is why no one on the MOTO GP uses a shaft drive motorcycle The total mass of the entire transmission system is much heavier than the chain drive.

 

Equipped with a high-quality china Motorcycle Transmission Shaft, turn the key with basketball ornament or slate ornaments, and bring a plastic beverage spout bag. They are convenient to carry. They only need to be placed in the bag and do not take up your space. They are very suitable for riding.

 

 

Chain drive

The biggest advantage of the chain drive is that it is cheap and has wide applicability, and when the engine is braking, there are many gaps between the chain links, so it can absorb part of the vibration. The disadvantage is that the friction between the chain and the gear will easily cause the chain to slack, and the gear will wear out, resulting in higher noise.

 

Belt drive

Structural characteristics of the belt

 

Its working surface is its two oblique sides, and many of the inner layers of the belt are made into tooth shapes, because it is designed to take into account the force of the belt when it is at the position of the pulley wrap angle.

 

When the belt is moving, the outer layer is stretched, and the inner layer is mainly affected by the squeezing force. Therefore, the inner layer of the belt is made into a tooth shape, which is more suitable for the force of the belt in these working positions, thereby extending the belt Service life.

 

Advantage

 

① Alleviate impact, absorb vibration, reduce noise, low cost, and convenient maintenance;

 

② Change the transmission ratio.

Disadvantage

 

① The belt drive is easy to slip and the transmission ratio is inaccurate

② Poor heat resistance, poor anti-overload ability, and easy aging

③ The transmission damping is large, especially when the car is cold. ④ The bearing is subjected to too much lateral force.

 

To put it simply, belt drive has the advantages of wide range of center distance, simple structure, stable transmission, buffer load and safety protection. The disadvantages are large outer diameter, low efficiency, inaccurate transmission ratio, and short service life.

 

In addition, belt drive, the transmission ratio is not accurate but can be overload protection. Gear transmission, accurate transmission ratio but no overload protection. Gears can be reversed, belts cannot. The belt drive mechanism is easy to maintain.

These three transmission modes have their own advantages and disadvantages, so according to different models and uses, different vehicles will be designed with different transmission modes.
