Technical Field
[0001] The utility model relates to the field of brake shoes, in particular to a synthetic brake shoe for railway diesel locomotives. Background Art
[0002] The brake shoe of a diesel locomotive is an important component used in the braking system. It is usually made of friction material to provide friction to slow down and stop the locomotive. The brake shoe is usually composed of a friction plate and a base plate, where the friction plate is the part that contacts the wheel.
[0003] Brake shoes can have a strong braking effect on locomotives, but there are still some problems: 1) The brake shoe of traditional brake shoes is not easy to disassemble, so the entire brake shoe structure needs to be disassembled for maintenance later, and subsequent maintenance and replacement of brake shoes are more difficult; 2) Traditional brake shoes will generate a lot of heat due to friction during braking, and their heat dissipation efficiency is slow, so the braking effect and service life will be affected; 3) When traditional brake shoes respond to the force in the direction of rotation, the force position is small, so the brake shoes are worn and unevenly stressed, and need frequent maintenance; Therefore, in view of the above situation, it is urgent to develop a synthetic brake shoe for railway diesel locomotives to overcome the shortcomings in current practical applications and meet current needs.
