A railroad car coupler draft gear is a critical device that connects railcars and cushions impact forces between the cars. A railway car coupler draft gear usually consists of a spring, a shock absorber and an energy absorbing element. They are designed to dampen shock and vibration during vehicle operation while transferring traction between vehicles.
⚡ Springs & Absorption
The springs in the shock absorbers absorb and disperse impact forces. They can be selected according to specific application needs to ensure sufficient elasticity and stability during transportation.

The mounting location for a railway vehicle coupler buffer is usually on a connecting part of the vehicle, such as the coupler or the connecting frame. Its function is to provide a cushioned connection point between vehicles in order to reduce shock and vibration.
✅
Summary: A railway car coupler draft gear provides a stable connection and shock mitigation through a combination of springs, shock absorbers and energy absorbing elements. They play an important role in railway transportation, protecting the safety of vehicles and passengers, and improving the comfort and reliability of railway transportation.
Frequently Asked Questions (FAQ)
Q1: What is the main function of a coupler draft gear?
It connects railcars and cushions impact forces, dampening shock and vibration while transferring traction between vehicles.
Q2: What is the difference between MT-2 and MT-3 models?
The MT-2 (AAR E) is suitable for formations over 5000 tons and vehicle weights over 80 tons, while the MT-3 (AAR F) is for formations under 5000 tons and vehicle weights under 80 tons.
Q3: What components make up a draft gear?
It typically consists of a spring, a shock absorber (often hydraulic), and an energy-absorbing element made of rubber or similar materials.
Q4: What industry standard do these draft gears follow?
These products are designed to measure up to the TB/T 2915 standard.
Q5: Where is the draft gear installed on a railcar?
It is usually mounted on the connecting parts of the vehicle, such as the coupler or the connecting frame.
Q6: How does the shock absorber work?
It often utilizes hydraulic principles to regulate fluid flow, providing stable absorption of vibrations and impacts during operation.
