This steering concept, developed during a 2nd stage of research, is based on previous experiences :
- Focusing stress on the CGM point (Contact Ground Mobile).
- Possibility of using the internal wheel space.
- Introduction of a second large diameter bearing.

Current techniques :
At present, steering pins are made up of two axle bearings or ball joints on the swivel pin with a variable ground clearance, which can be quite high in the case of two-wheelers.

OSMOS technique :
Our steering pin created for the orbital wheel is designed around a 2nd large diameter bearing in the hollow section of our circular runner and is slightly inclined with respect to the horizontal plane.

Improvements :
- Increased precision due to the elimination of effects of deformation at the level of    the stub axles and forks of the motorbikes.
- Elimination of structural stress, vibrations…
- Design that allows for the development of more rational steering systems in the    future.


Principle : A road vehicle's stability when proceeding in a straight line depends on the roll angle: the greater the angle, the more stable the vehicle. However, manoeuvrability will be reduced on turns and tight bends.

Current techniques :
Adopt the best possible compromise between stability and manoeuvrability or favour one or the other of these characteristics.

OSMOS technique :
The roll angle variator is a great step forward.
Designed along the lines of the single steering pin, the distinctive characteristic of this device is that the 2nd bearing is mounted on an articulated plate so that the roll angle is variable. The inclination of this plate is controlled by a speed-related double-effect hydraulic cylinder.

Improvements :
- The greater the speed, the higher the roll angle, and so maximum stability is
   maintained at all times.
- The reverse is also true. When the vehicle slows down, the roll angle is reduced
   thereby increasing manoeuvrability.


Current techniques :
The inflexible and complex solutions used preclude the possibility of creating variable drift steering.

OSMOS technique :
The Osmos wheel (free central space, single steering pin) has made this concept possible.
A circular plate (A), containing an eccentric axle bearing (B), is fitted into the second large bearing (C).
This eccentric axle bearing (B) constitutes the steering pin. In its normal position, the swivel pin passes through the midplane of the wheel.
Rotating the eccentric plate (A) to the left or right leads respectively to a negative or a positive wheel drift. This mechanism is controlled by an electronically-operated motor (D).
A central unit continually analyses the parameters picked up by sensors (speed, roll angles, drift, support surface, etc…) and decides on the necessary adjustments.

Improvements :
This system means improved roadholding and will undoubtedly be an added advantage in competition.


In spite of the significant progress made, braking systems remain a major source of concern for manufacturers of road vehicles and railway cars.

Current techniques :
Braking must occur at the centre of the wheel, which requires substantial energy and a complex brake structure.

Technique OSMOS :
The Osmos wheel is a great step forward:
- Possibility of mounting large diameter brake rings or discs.
- The grip can be located close to the ground where the forces act.
- The brake ring design with its peripheral support could lead to multiple ring brakes
   being produced in the near future.

Improvements :
- Increase of breaking power
- Breaking power applied close to the ground
- Excellent ventilation
- Possibility for further development
