Abstract
Abstract This invention relates to a suspension of a group of wheels of a vehicle, comprising two wheels located respectively on either side of the longitudinal plane of this vehicle and two suspension devices, each being constituted by at least one anti-roll bar and belonging to one of the two wheels, whilst each wheel is connected to one end of its suspension device and an elastic member is fixed to each of the ends of the suspension devices opposite the ends connected to the wheels, by coupling means, which are distinct from said elastic member and which are constituted by a part comprising two support elements between which the elastic member is disposed and by a member for fixing the suspension device in question to said coupling means, wherein the part comprising the two support elements is constituted by an arm which is provided on the one hand with the fixing member, on the other hand with a swell constituting a first of the two elements for supporting said part on a first face of the elastic member, and by a tie-rod integral with the arm and provided with a shoulder which is distant from the face of the arm provided with the swell, disposed opposite the said face and which constitutes the second of the two support elements of the part on a second face of the elastic member, which is opposite the first afore-mentioned face of said elastic member. The suspension described is applicable in particular to the manufacture of automobile vehicles.
