What are the common braking methods for mining electric locomotives?

2021-10-20
There are two types of braking methods for mining electric locomotives: the first type is mechanical braking, which is divided into three types: pure mechanical braking, hydraulic braking and air braking, and the second type is electric braking.
Mechanical braking is the use of brake shoes or brakes for braking. Its mechanism makes the brake shoes and the wheel fit tightly, and brakes with the help of the friction between the two. Pure mechanical brakes, as the name implies, have only mechanical parts. The braking force comes from people. People use levers, screws and other mechanical structures to achieve the purpose of pressing the brake shoes on the wheels. This method has slow braking response time, long braking idle travel time, inconvenient operation, and is easy to cause bearing wear. However, the structure is simple and reliable, so mining electric locomotives will be installed. Hydraulic braking and pneumatic braking are relatively labor-saving, and the braking force comes from hydraulic pressure and air pressure.
Electric braking is a braking method directly aimed at the motor. Commonly used electric braking methods include reverse braking, energy consumption braking, capacitive braking, and feedback braking.
The above is the common braking method of mining electric locomotive.
