Abstract
Abstract The suspension comprises an arm fast to a hub mounted on the body of the vehicle by means of a transverse rotary bearing, the hub being anchored to the end of a transverse torsion bar arranged in a tubular transverse member. The suspension comprises elastic means with variable flexibility arranged between the body and at least one arm fast in rotation to the tubular transverse member, the elastic means exerting on the arm an effect tending to oppose oscillating movement of the wheel upwardly with respect to the body. The suspension is particularly useful as a rear suspension for a light vehicle with front wheel drive.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
164 words
In a vehicle, a suspension in which the wheels of a same wheel train are each borne by a substantially horizontal wheel arm fastened to a hub which is mounted on the body of the vehicle by means of a transverse rotary bearing, the hubs of two wheel arms of a same wheel train being anchored at the respective ends of a transverse torsion bar positioned inside a tubular cross member to which it is anchored at a median zone, which cross member is itself mounted on the body in the vicinity of its ends, by means of supports, said transverse rotary bearings being positioned between each hub and the tubular cross member, at least one connecting arm rigid with the tubular cross member and elastic means of variable flexibility positioned between the body and connecting arm, said elastic means being adapted to exert on the connecting arm an effect tending to resist oscillating upward motion of the wheels with respect to the body.
Claim 2
Dependent Claim
164 words
In a vehicle, a suspension in which the wheels of a same wheel train are each borne by a substantially horizontal wheel arm fastened to a hub which is mounted on the body of the vehicle by means of a transverse rotary bearing, the hubs of two wheel arms of a same wheel train being anchored at the respective ends of a transverse torsion bar positioned inside a tubular cross member to which it is anchored at a median zone, which cross member is itself mounted on the body in the vicinity of its ends, by means of supports, said transverse rotary bearings being positioned between each hub and the tubular cross member, at least one connecting arm rigid with the tubular cross member and elastic means of variable flexibility positioned between the body and connecting arm, said elastic means being adapted to exert on the connecting arm an effect tending to resist oscillating upward motion of the wheels with respect to the body.
Claim 3
Dependent Claim
15 words
Suspension according to claim 1, wherein said elastic means are adapted to work under compression.
Claim 4
Dependent Claim
27 words
Suspension according to claim 2, wherein said elastic means are fixed on said connecting arm and are adapted to be supported on a portion of the body.
Claim 5
Dependent Claim
24 words
Suspension according to claim 2, wherein said elastic means are fixed to the body and are adapted to be supported on said connecting arm.
Claim 6
Dependent Claim
21 words
Suspension according to claim 1, comprising two said connecting arms, arranged in the vicinity of the ends of said cross member.
Claim 7
Dependent Claim
32 words
Suspension according to claim 2, wherein said elastic means are constituted by at least one element of elastomeric or similar material of such shape that its flexibility diminishes as its compression increases.
Claim 8
Dependent Claim
55 words
Suspension according to claim 6, in which the element, of plastics or similar material, is constituted by a stop including a top and a base, wherein the stop has a shape such that its cross sections along planes parallel to the mean support surface of the stop are non-decreasing from the top towards the base.
Claim 9
Dependent Claim
17 words
Suspension according to claim 6, wherein said element is constituted by a cushion formed of superposed rings.
Claim 10
Dependent Claim
33 words
Suspension according to claim 3, wherein the portion of the body on which said elastic means are supported is constituted by a transverse sectional member fixed to two longitudinal runners of the body.
Claim 11
Dependent Claim
59 words
Suspension according to claim 1, wherein the supports of the tubular cross member are constituted by sleeves of elastomeric material engaged around the cross member, whose inner surface is connected to the cross member or to a member fast to the latter and whose outer surface is connected to the body or to a member fast to the latter.
Claim 12
Dependent Claim
39 words
Suspension according to claim 1, wherein the supports of the tubular cross member are constituted by sleeves of elastomeric material of the fluid-block type, adapted to permit free rotation of the tubular cross member with respect to the body.
Claim 13
Dependent Claim
44 words
Suspension according to claim 1, wherein on each side of the vehicle, said elastic means are constituted by several elastic members, of constant but different flexibilities, arranged so as to enter successively into play in the course of the rotation of said connecting arm.
Claim 14
Dependent Claim
43 words
Suspension according to claim 1, wherein each said connecting arm extends on both sides of the tubular cross member and comprises, at its two ends, elastic means of variable flexibility adapted to cooperate with complementary supports provided on the body of the vehicle.
