Four Types Suspensions’ (Semi Trailer Parts) Brief Introduction
Connecting the running gear of the chassis and the frame of the vehicle, suspension of semi trailer is a vital part. Driving force,
brake force and loading force are all transmitted by the suspension system of the vehicle. Suspension also plays the shock absorption part,
that means, it protects the cargo from the impact force and guarantees the smooth and steady status of the vehicle during driving on the
rough ground. There are four types suspensions: mechanical suspension(trailer leaf spring suspension), air suspension, bogie suspension and
rigid suspension. Now, let us make a brief introduction for you.
1. Mechanical Suspension(Trailer Leaf Springs Suspension)
As the most commonly used suspension at home and abroad, it is made up of leaf spring, hanger, torque arm, etc.
- Reliable Performance
- Easy Maintenance
2. Air Suspension
With an air bag installed, its different structure decides its special applications that transport precision instruments, dangerous
mechanical materials, tobacco and cargo used in top fields.
- Lighter Weight
- Good Stability
3. Rigid Suspension
Rigid Suspension is not as commonly used as others. One single vehicle includes “two lines four axles”or “three lines six axles”
because of its axle of suspension is very short.
- High Loading Capacity with Low Speed
- Deliver Goods at Ports
4. Semi Trailer Bogie Suspension
It is a variation of mechanical.
- High Loading Capacity
- Heavy Duty Vehicle
