AMG Project One suspension

Most of the technologies and innovations in the automotive world come from Motorsports including suspension and powertrain. All the supercars and hypercars make use of technology used in the motorsports for almost all the systems. The Mercedes AMG project one suspension is one such example.

The Mercedes Benz AMG Project one

The AMG Project one is Mercedes Benz’s attempt to bring the supreme performance of the Formula-1 to the streets. Yes! you heard it right “The Formula-1 to the streets”. It has the Formula-1 powertrain with an electric motor for efficiency that is expected to launch in 2021 with a unique suspension setup that suits both for streets and the track. 

The suspension system

It is actually a Multi-link suspension, every arm is independent of the other with ball joints at the end. The suspension actuation is performed by the pushrods that will push the bell cranks , the bell cranks allow the dampers to be actuated. One of the big advantages of this system is the engineers don’t have to worry about the damper mounts. Only the bell crank has to be mounted and all other systems are mounted on to the bell cranks. Let’s have a look at the suspension setup.

Bump Load

When you consider a bump load, both the pushrods move upwards rotating the left bell crank clockwise and the other bell crank in anti-clock direction. The top damper ends up suffering compression and the bottom damper takes load in the same direction leaving it unloaded.

The lower damper setup

The lower damper setup has two dampers, the primary damper is designed to take compression loads when roll is experienced. The secondary damper is enclosed in an aluminum casing which is mounted to the bell crank and both the dampers are connected to each other. The other end is not connected and is free to move inside the aluminum casing. This damper compresses when the setup experiences a tensile load.

Roll: Compression on the lower damper setup

When you consider Roll, one wheel is forced downwards and the other is forced upwards. The right pushrod will move upwards whereas the other moves downwards. Now you can see from the image that the upper damper receives force in the same direction and the lower damper setup experiences a compression load this will compress the primary damper.

Roll: Tensile on the lower damper setup

When the roll is in another direction the top damper is unloaded and experiences a force in one direction. The lower damper setup will experience a tensile load and secondary damper acts and gets compressed.
