Suspension's windshields new look

Windshields of suspension are more aerodynamic with lower front profile so air drag will be lower too :)
Shock absorbers have better mounting angle now.

Cockpit view

Some raw cockpit pictures. With steering wheel Coupe4kW looks like real car now :)

coupe4kW aero aerodynamic shape

Coupe4kW with Tube suspension

Hi.
Coupe4kW aero with Tube Suspension looks better than any previous version :)

Tube Suspension is great for this project :) and Coupe4kW aero has more aerodynamic shape now :)








The invention of the new suspension type

Hi.
I invented today new kind of suspension. I called it Tube Suspension.
As I told you I need as simple as possible solutions - that's the reason when I feel badly when I look at McPherson's suspension - it has a lot of working elements so it is heavy, complicated, bad looking :) .

I need simpler aerodynamic suspension and  it need's to be light too!


Idea is simple :)
I need one shock absorber with coil spring
Mounting for the wheel directly on shock absorber

that's all :)

Some pictures of an idea

Leaf springs comeback :)

I've found this competition car with leaf springs suspension! I need to find leaf springs for my coupe 4kW!
This kind of suspension is the best for my car, because is light and aerodynamic :)




Even Ferrari team uses leaf springs suspension for their competition light car.

Pal-V tilting suspension in action movie


Suspension 3rd approach

McPherson's suspension is not good solution when it is outside the car, because of air drag.
I need suspension very light and very aerodynamic!
When every kWatt is important to have good range and low power consumption car's aerodynamic is as important as low weight.

NoVelo velomobile has rear tilting suspension and steering I was looking for.

McPherson suspension - short movie




Suspension McPherson concept

I did some research and it is not so easy to find leaf springs. Producing them, with dimensions and parameters I need can be to complicated and expensive.

I decided to change design to traditional McPhersons. It will be not so hard to find shock absorbers with springs for this solution. It is not so aerodynamicaly efficient as leaf springs, but looks nice and will be very stable :)

Suspension - movie


Suspension for coupe4kW aero

Suspension for coupe 4kW aero is simple because whole car is simple :)

Traverse leaf spring with shock-absorber and thats all. It is enough for medium speed and stabilise light car.

This type of suspension are used widely for small planes and it is very aerodynamicaly effective and very light.

Springs and shock absorbers in the front and the rear are the same - so it will be cheaper to produce.
