What is an actuator? Construction and cleaning of an actuator

The transmission plays an extremely important role for a mountain bike, not only as the engine that drives the whole bike, but also as a determining factor in performance for each different terrain surface. Please refer to this article with Tnhelearning.edu.vn to understand better!

What is an actuator?

The transmission, also known as “Groupset”, is a collection of parts such as forks, shifters, handlebars, chains… linked together to help the car operate smoothly. The transmission plays an extremely important role for a mountain bike, not only as the engine that drives the whole bike, but also as a determining factor in performance for each different terrain surface.

Structure of a transmission

Today, with increasingly advanced technology, the actuator also has a more sophisticated structure to meet all the different needs of users. However, in theory, a basic transmission of a mountain bike usually consists of 5 parts: the handlebar, the chain, the middle shaft, the shifter and the fork.

– Handlebar: This is a part mounted next to the handle with the main function of controlling the starter. The handle consists of 2 details, the left hand and the right hand. Each hand will take on a different task. The left hand lever moves the chain to the discs and the right hand shifter moves the chain to the cassette stages. However, some sports bikes will not be designed with a left hand lever like city bikes or racing bikes. Because only one floor is designed, these cars usually only have a right hand lever.

– Shifting forks: Usually for bicycles, there are usually one, two to three forks. For a sport bike with 2 front forks, it is often called a double disc. As for the sports bike with 3 bands, it is called a trio. With a sprocket on which the gears are, with the gears helping to transmit the force from the pedal to the sprocket arm to the gears that transmit to the chain to the rear cassette.

– Fork spring: An important part to help optimize the height for the rider to be comfortable and limit muscle fatigue. Normally, there are 3 types of spring rolls: one plate, two forks and three forks. Depending on the number of discs, they have the same operating mechanism. The flexible number of forks gives users more options to suit their needs, helping to save costs.

– Middle shaft: It can be said that now there are many types of rotating shafts with different materials, some popular bottom brackets such as: BSA, BB30, BB86-89.5-92 Press Fit, PF30… Depending on the set The transmission will correspond to the rotating shafts of different sizes.

– Chain: Is a chain consisting of rollers connected by masterlink. As each roller moves, power is transferred from the pedal to the center of the wheel, causing the wheel to spin. Most bicycle chains are usually made from carbon steel or copper alloy steel, but some are plated with nickel to prevent rust or simply increase aesthetics.

Check and clean each part

Regular cleaning not only helps the car operate smoothly but also helps to increase the life of spare parts, helping users save a lot of money.

– Handlebar: First you push the chain up – down the disc, here including the starter when moving a lot, you adjust the H – L screws to, stretch and re-adjust the position of the car’s starter if it is deflected during the process. During use or not, see if there is dust or dirt, if so, lightly rinse with water from the top to then wipe it clean.

– Shifting discs: Check the gear heads for wear or not. If yes, replace it with a new fork because if not replaced, it is easy to lose the slug when moving, causing damage to the slug and unsafety.

– Spindle: Do an inspection and make sure it doesn’t have any serious cracks. Pay attention to roundabouts as they can bend or crack from chain impacts. You can use a brush to clean them and then wipe them with a dry cloth.

– Center axle: Use a support tool to remove the front fork to remove the middle axle of the vehicle. Continue to use a small brush to soak the solution thoroughly scrub the shaft from the inside out. The last step is to lubricate and reinstall as original.

– Car slug: You prepare a pad to catch dirt and a brush soaked in cleaning solution for the car’s slug. Gently rub the slug eye from top to bottom and from left to right, then rinse with water and wipe with a dry towel. Finally, apply oil to the car so that the car can drive smoothly and achieve the highest efficiency.
