Mechanical brakes mostly use friction to consume system kinetic energy and produce braking effect
Under the same power consumption, the higher the shaft speed, the smaller the corresponding torque that needs to be transmitted . Because power = torque × angular velocity.
Arranging the mechanical brake on the high-speed shaft can reduce the resistance torque that the brake needs to provide under the same braking power, thereby reducing the size of the brake and reducing the cost of the brake.
Aluminum alloy. According to relevant public information inquiries, aluminum alloys have small mass, high strength, and good thermal conductivity. High-strength aluminum alloys are generally used for pistons, but some low-speed diesel engines use high-grade cast iron or heat-resistant steel. The piston is a reciprocating part in the automobile engine cylinder block. The basic structure of the piston can be divided into top, head and skirt.
