Abstract
A suspension method for stabilizing a bicycle frame is provided with an elastically deformable damping suspension in order to absorb shocks, wherein said method consists of elastically deforming a suspension device by a torsional effect perpendicularly to the bicycle frame. The suspension device extends over a frame plane and is fitted out to implement the method by providing a damping torsional means arranged about at least one axis contained in a torsional plane perpendicular to the frame plane.

A suspension method for stabilizing a bicycle frame and provided with an elastically deformable damping suspension in order to absorb shocks, wherein said method consists of elastically deforming said suspension device by a torsional effect generally perpendicular to the bicycle frame.
A suspension device for stabilizing a bicycle frame comprising:
- a bicycle frame extending over a frame plane;
- and
- means for damping torsion about at least one axis contained in a torsional plane perpendicular to the frame plane, the means mounted to the bicycle frame.
A bicycle frame comprising:
- a tubular rigid structure which extends substantially over a frame plane,
- at least one wheel fork being made up two tubular arms symmetrically arranged in view of the frame plane and defining a medium longitudinal direction in the frame plane, and
- at least one suspension device linking the wheel fork to the tubular rigid structure to absorb shocks,
- wherein said suspension device comprises a means for damping which is torsionally deformable about an axis, said axis being at an angle substantially ranging between 30 and 90 degrees with respect to the medium longitudinal direction.
A bicycle provided with a frame comprising:
- a tubular rigid structure which extends substantially over a frame plane, the rigid structure of which having a crank gear,
- two wheel forks, a front and a rear one to fit respectively a front and a rear wheel, at least one wheel fork being made up two tubular arms symmetrically arranged in view of the frame plane and defining a medium longitudinal direction in the frame plane, and
- at least one suspension device linking the wheel fork to the tubular rigid structure to absorb shocks,
- wherein said suspension device comprises a means for damping which is torsionally deformable about an axis, said axis being at an angle substantially ranging between 30 and 90 degrees with respect to the medium longitudinal direction.
