chassis car diagram

シャーシ車図

The exterior of the body as well as a strong frame that protects the cabin from impact. The chassis of this model is relatively more protective of passengers from impact impact during collision. The impact energy is absorbed by the body and not transmitted to the cabin. Usually this monokok chassis is accompanied by a crumple zone (front and back) that will be folded like paper during a collision.

Actually this one piece chassis is formed from several parts that unite. Cabin deck is the largest part that is united with other parts via a stamping machine (big press machine). New then added point welding or hinge with other body panels such as doors, hood, until the trunk door.

Construction Monokok was first used in the aircraft industry. But in its development this technique is also applied to the assembly of cars. Lancia Lambda first used a monoclear chassis in 1923. Then Citroën Traction Avant in 1934 was the first monocle mass product with monokok.

Currently, 99% of mass product vehicles are already using monocoach steel chassis, due to low production costs and can be combined with assembly using a robotic system.

Advantages:

- Space efficiency

- Protection of the cabin in the event of an accident

- The cost is relatively cheap for production

Weakness:

- Weight is quite heavy

- Not suitable for production in small quantities
