Car Clutch: How it Works and When to Check it
Today we will talk about a fundamental component of our cars, the clutch, which we often neglect, but which can often meet a whole series of more or less serious problems: we will try to understand how it works and which are the alarm bells that should do us run in the workshop.
How does the car clutch work?
The clutch is the mechanism that allows transferring the motion from the engine to the change of the car; consists of three components:
- Clutch plate: consisting of friction material in the outer ring, a pack of springs that dampen the vibrations and a grooved profile in the central hole, which follows the one in the shift shaft.
- Clutch plate: consisting of a set of blades connected to a steel disk
- Thrust bearing: it can be mechanically or hydraulically operated and is located in the center of the pressure plate.
When we press the clutch pedal the movement is transmitted to the thrust bearing that carries the pressure plate back: in this way, the movement of the engine is no longer transmitted to the gearbox and it is possible to change gear.
Raising the pedal, the bearing and pressure plate move towards the engine flywheel and the pressure plate presses on the clutch disc, making it progressively adhere to the engine flywheel until it rotates at the same speed due to friction. At this point the clutch disc will again engage with the gearbox shaft spline, transferring it to the gearbox.
In practice, the clutch works in conjunction with the engine’s flywheel, and is one of the most important components of the car, and also of the most delicate, whose average duration varies greatly depending on the driving style and the types of routes performed by the cars :
- In cars that run mainly on city streets, the clutch could wear out already after 70/80 thousand
- In those driven mainly on the motorway, it could easily reach 150,000 kilometer, without presenting any problems.
Car clutch: how to notice that something is wrong?
The clutch problems are among the most common among those that can be found in a car, and all car models are subject to them, from city cars to extra-luxury sedans. Here are the alarm bells that should lead us to have it checked:
- While maintaining a steady pace, the tachometer of your car goes up a lot without rewarding the accelerator.
- The point where the clutch detaches has undergone changes.
- The clutch pedal does not work properly: it is hard or remains at the end of the race and it is difficult to get back up.
- The gear lever vibrates.
- The clutch at the start tears or slides.
- Gear changes are rough or less fluid
All these symptoms are not to be underestimated, as they are indicative of the fact that some of the components of the clutch have undergone more or less serious alterations: in the best of cases a replacement of the oil in the gearbox will suffice, in the worst case the whole will have to be replaced clutch .
The duration of the latter also depends very much on the type of driving: it is a good habit to drive by completely removing the foot from the clutch pedal and, when changing gear, to “use” as little as possible.
One of the most common problems that occur when the clutch is mistreated is that of the so-called “slipping clutch”: in practice the disc runs on the flywheel of the engine and remains glued to it, making gear changing very difficult or even impossible.
Before arriving at this point we advise you to pay close attention to the signals that your car sends, without forgetting to have the clutch checked periodically, to avoid serious damage.
If you have an old car that is problematic with the clutch, you might consider selling it since it would be very expensive to get it fixed and may not be worth it considering your car’s condition.
