2. The support according to claim 1 , wherein the trajectory (T) of the guide element ( 6 ) is defined by an arcuate groove ( 7 ) concentric to the main rotation axis (X).
3. The support according to claim 1 , wherein the guide element ( 6 ) is solidly constrained to the second attachment body ( 31 , 32 ) with respect to the translation perpendicular to the main rotation axis (X).
4. The support according to claim 2 , wherein the arcuate groove ( 7 ) is made on the first attachment body ( 2 ).
5. The support according to claim 4 , wherein the guide element ( 6 ) is in the form of a pin arranged inside the arcuate groove ( 7 ) and is solidly constrained to the groove itself with respect to the translation parallel to the main rotation axis (X) by striker plates ( 6 a , 6 b ) arranged on opposite parts of the first attachment body ( 2 ).
6. The support according to claim 1 , wherein the guide element ( 6 ) is provided with shock-absorbing means ( 61 ) predisposed to absorb at least partially the stresses directed parallel to the main rotation axis (X).
7. The support according to claim 5 , wherein the guide element ( 6 ) is provided with shock-absorbing means ( 61 ) predisposed to absorb at least partially the stresses directed parallel to the main rotation axis (X), and wherein the shock-absorbing means ( 61 ) is interposed between the striker plates ( 6 a , 6 b ) of the guide element ( 6 ) and the first attachment body ( 2 ).
8. The support according to claim 1 , wherein the first attachment body ( 2 ) is in the form of a shaped plate equipped with fastening means ( 21 ) for the fastening thereof to the support ( 91 ) of a wheel.
9.
