Understanding motorcycle transmission and smooth driving
What is a motorcycle transmission? Some say "it's a transmission", but this description is not comprehensive. If it is a simple transmission device, it can be completely replaced by chains and belts, and there is no need to design a lot of gears and parts, cumbersome transmission.

    The ultimate purpose of a motorcycle transmission is to amplify the performance of the engine so that it can pass through different motorcycle gear.

    And the current power is strengthened again to achieve a more ideal effect to achieve a balanced performance between power and fuel consumption, so that its performance is more suitable for the needs of different scenarios.

    Structural analysis of a motorcycle transmission

    Motorcycle transmissions usually consist of multiple gears and clutches. Among them, the gears are used to change the gear ratio, and the clutch is used to connect or disconnect the engine from the gearbox.

    • Main gears

    The main gear is one of the core components, which is connected to the engine crankshaft and is responsible for transmitting the power of the engine. The number of teeth of the main gear determines the gearbox ratio.

    • Gears in all gears

    Motorcycle transmissions usually contain multiple gears, each corresponding to different driving gears. These gears are connected to the main gears by the connection of the clutch, and different ratios are achieved through different combinations.

    Generally speaking, the lower gear has a larger gear and can provide a higher torque output, while the high gear has a smaller gear and can provide a higher speed.

    • Clutch

    The clutch is used to connect or disconnect the engine from the gearbox. When the motorcycle clutch is connected, the power of the engine can be transmitted to the gearbox. When the clutch is disconnected, the connection between the engine and the gearbox is cut and the power of the engine is no longer transmitted.

    How motorcycle transmissions work

    The working principle of the motorcycle transmission is that when the transmission pedal assembly is pressed with the foot, the transmission shaft rotates accordingly, and the shift arm body S that is welded together with the transmission shaft swings accordingly (motorcycle speed wobble).

    The shift arm is connected with the main body of the shift arm with a pin, and the shift arm is always pulled upwards with a tension spring. This is because there is a slot on the other end of the shift arm in which the two dowel pins are located.

    Therefore, the gear shift arm always presses the dowel pin under the action of the tension spring, and pulls or pushes the dowel pin to move along the direction of movement of the shift arm under the action of the groove hook.

    How motorcycle transmissions work

    The general requirements for motorcycle transmissions are:

    • It has high transmission efficiency.
    • Gear changes should be light and free of impact.
    • The gear works smoothly without impact and abnormal sound.

    What are the functions of motorcycle transmissions

    Motorcycle transmissions are able to adjust the speed and traction capacity of the vehicle according to different road conditions and driving conditions to adapt to different driving needs.

    When driving on a flat road, the vehicle can travel at a higher speed, whereas when driving on an undulating road or ramp, the vehicle needs to reduce its speed to increase the traction of the vehicle.

    Of course, it is also possible to change the engine speed and torque by controlling the throttle opening. However, the range of traction variations is very small, and it is far from meeting the needs of motorcycle driving.

    What are the functions of motorcycle transmissions

    At this time, motorcycle transmission is required to expand the range of torque and speed changes, so that the lightweight electric motorcycle has the right traction and speed. In order to adapt to the often changing driving conditions, while keeping the engine running at the best power and fuel consumption at the most economical conditions.

    Three common types of motorcycle transmissions

    Motorcycle transmission is an important unit that is easily overlooked by manufacturers and users, and the main reason why it is ignored is that it is relatively simple. Here, Benlg is going to introduce it.

    In particular, compared to cars, there is no detailed category at present, and it is mainly based on foot and automatic. Of course, high-end models will also use electronically controlled manual refitting or electronic fast transmission, the former is similar to a car DCT, and the latter is more of an auxiliary device.

    However, for common motorcycles, its current transmission is mainly automatic separation of continuously variable transmission, automatic separation of continuous transmission, manual separation of continuous speed transmission of three types.

    Among them, manual separation and stepless transmission are more common, and there will be more application scenarios, accounting for 2/3 of all types of models on the market.

    Three common types of motorcycle transmissions

    The other two types of transmissions are more specific, and automatic separation and continuously variable transmission are often used by scooters. The automatic separation of the continuously variable speed is mainly used in the curved beam model. Which of these three common motorcycle transmissions is best?

    It depends mainly on its own structure and actual effect. In terms of market ownership, manual separation of the continuously variable gearbox is the most reliable, automatic separation of the continuously variable gearbox has disadvantages, and automatic separation of the continuously variable gearbox is better.

    Advantages of motorcycle transmissions

    Compared to a single-speed transmission system with a fixed gear ratio, motorcycle transmissions have the following advantages:

    • Multiple levels are available

    Motorcycle transmissions are available in a number of different gear ratio options, allowing the driver to choose the right driving gear according to driving conditions and personal needs. This can not only meet the needs of climbing and starting at low speeds but also meet the speed and fuel economy requirements at high speeds.

    • Improves driving comfort

    With a reasonable combination of gears, the motorcycle transmission can operate at different speeds, providing a smoother power output. This reduces engine load and noise and improves driving comfort and stability.

    Advantages of motorcycle transmissions

    • Improved fuel economy

    Motorcycle transmissions allow the engine to operate at the optimum operating speed range, providing a higher fuel economy. With a reasonable combination of gears, engine speed can be reduced, energy loss can be reduced, and fuel efficiency can be improved.

    Conclusion

    Motorcycle transmission is an important part of the motorcycle through a reasonable gear combination and clutch control to achieve different speeds and torque outputs.

    It not only provides multi-gear selection and driving comfort but also improves fuel economy. For motorcycle drivers, it is very important to understand the principles of motorcycle transmission so they can better master their driving skills and improve their driving safety and experience.
