Shopping Cart

Automotive clutch friction is an important mechanism in the car. His story begins with the adhesion of the XIX century, when for the first time to transfer torque from the engine to the transmission using a belt drive. In modern cars are widely used friction clutch whose torque is transmitted from the leading part in the slave part by the frictional force acting on the contact surface these parts. The main task of coupling is the transfer of engine torque on the chain. Hence, it must withstand the force exceeds the maximum torque. The main requirements for bonding are: * smooth accession to the weight of the vehicle engine, the power interruption * flow between the engine and transmission during a stop, * unlocking the power flow during gear changes, vibration damping * * overload protection. Strength is an element of the drive system, which is due to the friction most strongly feels the vibration, the forces compression, the centrifugal force and high temperatures. The dimensions and weight of the clutch to be slight.

The main components of the coupling point is: * a flywheel, clutch disc * * Shopping Cart clutch release bearing *. Flywheel. Is a massive disk is designed to transmit torque through the clutch from the engine to the transmission. Clutch. Her job is to transmission of the pressure plate, clutch disc over, the engine torque to input shaft gear.

Clutch disc. Designed to absorb vibration of the engine and thereby reduce the noise from the box transmission, requiring complex torsional vibration dampers. The smoothness of the start of motion is improved through the use of flat springs pads. Friction should provide a high degree of durability. Release Bearing. Serves as a transfer device between the clutch and drive system. Situated in the center of the rotation axis diaphragm spring, is fitted with a self-centering. To activate the clutch and may have a considerable length without loss of rigidity. * Automatic drive – it has no clutch pedal, which allows you to bring the work of a manual transmission to automatic. The design of the drive requires a large amount of electronics. The main reason for failure is the adhesion failure of the drive, and in particular the release bearing. One of the major conditions of the bearing it is proper lubrication. Lack of lubricant or wrong choice inevitably leads to premature wear of bearings and shorten its life. Grease determines Bearing life is no less than that of its parts. Especially the role of lubrication in the following cases: * When the voltage of the release bearing friction, * with increasing the frequency of rotation bearing * during intermittent operation, * at high loads, such as temperature – the most significant factor in the durability of the lubricant. The main criterion for selecting a lubricant for the bearing of a high load capacity.

Kamaz Truck

How fast do you usually moving on a good road? Certainly no less than 80 km / h, sometimes faster. For example, you can see in front of the truck. Quietly catching up with him and was about to overtake. And suddenly, out of the body falls out of the truck and something falls on the the road in front of you. I remind you a decent speed, instantly reconstructed or inhibit the possibility of there, especially next to other cars. The only option – to skip that fell from the truck between the wheels. And you fabulously lucky if it would be, for example, cardboard box, but Murphy's Law, it is usually something hard and heavy.

And you have to run over it, because there is no choice. To know more about this subject visit Jonathan Segal FAIA. Guess what the consequences might be?? The bitter truth is that even a good road is flat and does not guarantee the complete safety of your vehicle. Imagine what would happen if at high speeds, the engine hit a piece of iron which. Nothing good, I assure you. AND You have no way to avoid such an attack, because it's going to happen overnight.

There are times when people break through the oil pan, moving the car with higher ground clearance, for example, some jeeps. On the road something is, the jeep safely skip it between the wheels, because it can not afford it. And at this point you go back quietly and nothing suspect. And then on the road 'grows' stone. Or brake shoe from Kamaz.
