Cyclists, who rarely go to ride, probably did not even hear about what a bicycle carriage is. Even if they heard, they do not know where it is and what it is. But for those who often use the bike 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 knot? This mechanism is almost the main thing in the whole bike. Without it, he will not go anywhere. Where is he located? It is located in a glass (this is such a special place), namely, where there are rods. The main task is to fasten the same connecting rods to each other and connect them to the frame. Without it, the cyclist will simply not be able to pedal, and therefore move forward.
Bicycle carriage device
What does this node consist of and what is it like? Bicycle models are different, so the carriages also differ from each other. The standard is sixty-eight millimeters, but there are also one hundred and ten, one hundred and thirteen, and so on.
Also bicycle carriages are divided into two types: collapsible and cartridge (non-collapsible). Each type has its pros and cons. Let's start with the kartzhdnyh. This type can not be repaired - this is its main feature. If the mechanism rusts or breaks, then it can already be just thrown out. But they have a big plus. They are very durable. Such a bicycle carriage will serve until its bearings are erased. The mechanism is sealed, so foreign objects in the form of dust, sand, water and the like do not get there, thus it is protected from rapid wear. Such carriages behave very well even after long-term operation in harsh conditions, so manufacturers often like to install them on mountain bikes.
Collapsible carriages - this is a slightly different device. In essence, this is just the axis on which the bearings are mounted. In this case, the owner must at least occasionally check this assembly and, if necessary, lubricate and replace damaged bearings. Such care will allow much longer life of the mechanism.
How to determine the fault carriage?
No mechanism will last forever, especially if you do not follow it. That is why sooner or later the carriage mechanism will come to malfunction. How to determine the fault? Generally, it is not difficult. You just need to be careful. The first sign is a hard ride. If suddenly it became difficult to pedal, then perhaps this is a carriage malfunction. The dirt does not allow the mechanism to function in normal mode, so it becomes hard to go. Squeaks and knocks are also characteristic. Due to jumps and strong physical exertion, the axle may skew, or the bearings will break. In this case, there will be a backlash.
If, when riding, the pedals start to jam or squeak strongly, then this is a sure sign of a disruption to work. There is already a need to repair the carriage of the bike. Or just replace the node with a new one.
How to remove the carriage from the bike?
So, to repair the mechanism, you first need to remove it, remove it from the glass. Before starting work, you need to clean the place around the carriage. It is necessary to remove all adhered dirt and dust. All this is done in order to then not bring all the garbage inside.
How to remove the carriage from the bike? First you need to remove the plugs that close access to the nut of the connecting rod. To quickly get to the mechanism of interest, you need special keys: a crank squeeze and a carriage tenant.
First you need to insert one end of the crank pinch and unscrew the nut. Then insert it with the other end and screw it in by force. Thus, the rod comes off the axis and it can be removed. The same needs to be done from the other side. It is best to start work from the side where there are no stars.
The next step is carriage removal. This is where a special renter comes in handy. We insert it, and on the other hand we put on the wrench. With a little effort, you can get to the device. We carry out similar actions on the other hand. The carriage is now ready for removal. If the device is in more or less good condition, then it will cost only lubrication of bearings. For this it is best to use a thick lubricant. Going carriage bike in reverse order.
