1. A suspension assembly for an endless belt drive, the suspension assembly comprising: a first wishbone adapted to pivotally secured, at a first end thereof, to a frame of a vehicle;a second wishbone adapted to be pivotally secured, at a first end thereof, to the frame the first wishbone pivotally connecting the hub at a second end thereof, the second wishbone pivotally connecting the hub at a second end thereof, the hub being adapted to move vertically in respect with the frame in accordance with the angular displacement of the first wishbone and the second wishbone;a tandem member including a first end and a second end thereof, the tandem member being pivotally secured to the hub; andat least two wheels being respectively attached to the first end and the second end of the tandem member, the at least two wheels being adapted to contact the endless belt to support the vehicle. 2. The suspension assembly of claim 1, wherein the at least two wheels are at least two pairs of wheels. 3. The suspension assembly of claim 1, wherein the tandem member is pivotally secured to the hub at a pivot substantially located in the middle of the distance separating the at least two wheels. 4. The suspension assembly of claim 1, wherein the hub is pivotally secured on two sides thereof by the first wishbone and the second wishbone. 5. The suspension assembly of claim 1, wherein the first wishbone and the second wishbone are respectively proximally pivotally connected to a wishbone support intervening between the first wishbone and the second wishbone and the frame. 6. The suspension assembly of claim 1, further comprising a pneumatic airbag suspending the hub in respect with the frame. 7. The suspension assembly of claim 6, further comprising a lower pneumatic airbag support connected to the pneumatic airbag and pivotable about one of the wishbones and a stabilization member, the stabilization member being connected to the lower pneumatic airbag support to define an angle thereof relative to the suspension displacement. 8. The suspension assembly of claim 6, wherein an air compressor is operatively connected to changes a pressure in an auxiliary fluid reservoir operatively connected to the pneumatic airbag in function of at least one factor selected from the group consisting of a mass distribution of the vehicle, a longitudinal inclination of the vehicle and a distance between the frame of the vehicle and the ground. 9. The suspension assembly of claim 1, wherein a lateral displacement of the at least two wheels along the vertical travel of the suspension is about less than 5 millimeters. 10. A vehicle equipped with a suspension assembly for an endless belt drive, the suspension assembly comprising: a first wishbone adapted to be pivotally secured, at a first end thereof, to a frame of a vehicle;a second wishbone adapted to be pivotally secured, at a first end thereof, to the frame the first wishbone pivotally connecting the hub at a second end thereof, the second wishbone pivotally connecting the hub at a second end thereof, the hub being adapted to move vertically in respect with the frame in accordance with the angular displacement of the first wishbone and the second wishbone;a tandem member including a first end and a second end thereof, the tandem member being pivotally secured to the hub; andat least two wheels being respectively attached to the first end and the second end of the tandem member, the at least two wheels being adapted to contact the endless belt to support the vehicle. 11. The vehicle of claim 10, wherein the at least two wheels are at least two pairs of wheels. 12. The vehicle of claim 10, wherein the hub is pivotally secured on two sides thereof by the first wishbone and the second wishbone. 13. The vehicle of claim 10, wherein the first wishbone and the second wishbone are respectively proximally pivotally connected to a wishbone support intervening between the first wishbone and the second wishbone and the frame. 14. The vehicle of claim 10, further comprising a pneumatic airbag suspending the hub in respect with the frame. 15. The vehicle of claim 14, further comprising a lower pneumatic airbag support connected to the pneumatic airbag and adapted to pivot about one of the wishbones and a stabilization member, the stabilization member being connected to the lower pneumatic airbag support to define an angle thereof relative to the suspension displacement. 16. The vehicle of claim 10, wherein a lateral displacement of the at least two wheels along the vertical travel of the suspension is about less than 5 millimeters. 17. A suspension assembly kit for an endless belt drive, the kit comprising: a first wishbone adapted to be pivotally secured, at a first end thereof, to a frame of a vehicle;a second wishbone adapted to be pivotally secured, at a first end thereof, to the frame the first wishbone pivotally connecting the hub at a second end thereof, the second wishbone pivotally connecting the hub at a second end thereof, the hub being adapted to move vertically in respect with the frame in accordance with the angular displacement of the first wishbone and the second wishbone;a tandem member including a first end and a second end thereof, the tandem member being pivotally secured to the hub; andat least two wheels being adapted to be respectively attached to the first end and the second end of the tandem member, the at least two wheels being further adapted to contact the endless belt to support the vehicle. 18. The suspension assembly kit of claim 17, wherein the at least two wheels are at least two pairs of wheels. 19. The suspension assembly kit of claim 17, further comprising a wishbone support and wherein the first wishbone and the second wishbone are adapted to be respectively proximally pivotally connected to the wishbone support intervening between the first wishbone and the second wishbone and the frame. 20. The suspension assembly kit of claim 17, further comprising a pneumatic airbag adapted to suspend the hub in respect with the frame. 21. The suspension assembly kit of claim 20, further comprising a lower pneumatic airbag support adapted to be connected to the pneumatic airbag and adapted to pivot about one of the wishbones and a stabilization member, the stabilization member being adapted to be connected to the lower pneumatic airbag support to define an angle thereof relative to the suspension displacement. 22. The suspension assembly kit of claim 17, wherein an air compressor is adapted to be activated to change a pressure in an auxiliary fluid reservoir adapted to be operatively connected to the pneumatic airbag in function of at least one factor selected from the group consisting of a mass distribution of the vehicle, a longitudinal inclination of the vehicle and a distance between the frame of the vehicle and the ground.
