Cyclists who rarely ride out, probably did not even hear about what a bicycle carriage is. Even if they heard, they do not even know where it is and what it is. But for those who often use a bicycle for their own purposes or engaged in cycling, this site is of great importance. What is a bicycle carriage, what are its functions and how to fix it now and find out.

What is it like?

What is a carriage assembly? This mechanism is almost the main thing in the whole bicycle. Without him, he will not go anywhere. Where is it located? It is located in a glass (this is a special place), namely, where the rods are located. The main task is to fasten those connecting rods together and connect them to the frame. Without it, the cyclist simply can not twist the pedals, which means moving forward.

Bicycle Carriage Assembly

What does this node consist of and how does it happen? Models of bicycles are different, so the carriages also differ from each other. The standard is sixty-eight millimeters, but there are also a hundred and ten, one hundred and thirteen, and so on.

Also, the bicycle carriages are divided into two types: collapsible and cartridge (non-separable). Each type has its pros and cons. Let's start with the picture. This type can not be repaired - this is its main feature. If the mechanism rusts or breaks, it can already be thrown out. But they have a big plus. They are very durable. Such a carriage of a bicycle will serve until its bearings are erased. The mechanism is hermetically sealed, so foreign objects in the form of dust, sand, water and the like do not enter there, thus it is protected from rapid wear. Such carriages are very well behaved even after a long operation in severe conditions, so manufacturers like to often install them on mountain bikes.

Demountable carriages are a little different device. In fact, this is just the axis on which the bearings are mounted. In this case, the owner needs to at least occasionally check this unit and, if necessary, lubricate and change the damaged bearings. Such maintenance will greatly prolong the life of the mechanism.

How to determine the carriage malfunction?

No mechanism is eternal, especially if you do not follow it. That is why sooner or later the carriage will come to a malfunction. How to determine the fault? In general, it is not difficult. You just need to be careful. The first sign is a heavy ride. If suddenly it became difficult to twist the pedals, then, probably, this is a carriage failure. Stuck dirt does not allow the mechanism to function in normal mode, so it's getting hard to ride. Scripts and knocks are also characteristic. Because of jumps and strong physical loads, the axle can warp, or the bearings will break. In this case, there will be a backlash.

If pedals start to jam or strongly squeak when driving, this is a sure sign of a malfunction. There is already need to repair the bicycle carriage. Or just replace the node with a new one.

How do I remove the carriage from a bicycle?

So, to repair the mechanism, it must first be removed and extracted from the glass. Before you start work, you need to clean the place around the carriage. It is necessary to remove all the adhering dirt and dust. All this is done in order to not then bring all the garbage inside.

How do I remove the carriage from a bicycle? First you need to remove the plugs that close the access to the connecting rod nut. To quickly get to the mechanism of interest, you need special keys: crankshaft and the carriage renter.

First you need to insert one end of the crankwatches and unscrew the nut. Then insert it with the other end and force it in. Thus, the connecting rod comes off the axis and can be removed. The same thing needs to be done on the other side. It is best to start work from the side where there are no stars.

The next step is to remove the carriage. Here is already useful special tenant. We paste it, and on the other hand we put on a wrench. With a little effort, you can get to the device. We carry out similar actions from the other side. The carriage is now ready for removal. If the device is in a more or less decent condition, then the deal will cost only the lubrication of the bearings. To do this, it is best to use thick grease. The carriage of the bicycle is assembled in the reverse order.
