Automobile brake camshaft for many people are very unfamiliar, many people have not even heard of the bottom, so what is the automobile brake camshaft? Secondly, automobile brake camshaft is an important part of the automobile, is one of the parts in the piston engine, the main body of the camshaft is a cylindrical rod with the same length as the cylinder. There are several cams on it to drive the valve. One end of the camshaft is the bearing support point, and the other end is connected with the driving wheel.
In terms of structure, the side of the CAM is egg shape. The first is to complete the valve opening and closing operation in as short a time as possible to ensure that the cylinder is full of air intake and exhaust. Camshaft from variety including integral and combined, although there are many parts, but the core is the CAM. When the car brake camshaft rotates, the CAM will follow the movement of the piston in time to open/close the intake and exhaust valves.
Generally speaking, the speed of automobile brake camshaft is very high, and the need to accept relatively large torque, so the design of camshaft in strength and support requirements are particularly high, its material is usually special cast iron, sometimes also choose forgings. Because the valve movement is related to the power and working characteristics of an engine, camshaft plays a very important role in the design of automobile engine.
