Mounting assembly for unsteerable wheels
First Claim
1. An axle and suspension assembly for mounting two unsteerable wheels of a motor vehicle having a rigid structure, comprisinga crosspiece;
- two resilient mounting bodies, which are spaced apart along said crosspiece and secured to the latter and adapted to be secured to said rigid structure, said mounting bodies providing a resilient connection between said crosspiece and said rigid structure, each of said mounting bodies having different stiffnesses in different directions in a generally horizontal plane;
two wheel carriers, each of which carries one of said wheels;
linking means linking said wheel carriers to said crosspiece at opposite ends thereof and permitting each of said wheel carriers to perform a vertical movement relative to said crosspiece;
constraining means connected to said wheel carriers and adapted to be connected to said rigid structure so as to constrain said wheel carriers to move in a generally vertical direction relative to said crosspiece and said rigid structure;
hinge means provided with elastic liners and hingedly interconnecting parts of said assembly to each other and adapted to hingedly connect said assembly to said rigid structure;
two diagonal struts hingedly connected by said hinge means to said crosspiece and adapted to be hingedly connected by said hinge means to said rigid structure so that the longitudinal axes of said diagonal struts intersect to the rear of said assembly,said linking means associated with each of said wheel carriers comprising two lower transverse control arms, which have longitudinal axes intersecting at a point that is disposed on the outside of and axially spaced from the adjacent one of said wheels, anda longitudinal control arm hingedly connected by said hinge means to each of said wheel carriers and adapted to be connected by said hinge means to said rigid structure.

Abstract
An axle and suspension assembly for mounting two unsteerable wheels of a motor vehicle comprises a crosspiece secured by means of elastic mounting bodies to a rigid structure of the vehicle. The mounting bodies have different stiffnesses in different directions in a generally horizontal plane. Two wheel carriers are linked to the crosspiece by means of two lower transverse control arms arranged at acute angles to each other, and, in addition, each wheel carrier is connected to the rigid structure by a longitudinal control arm. The crosspiece is also connected to the rigid structure of the vehicle by two diagonal struts.

10. A motor vehicle comprising a rigid structure, two unsteerable wheels, and an axle and suspension assembly for mounting said two unsteerable wheels on said rigid structure, comprising
a crosspiece; -
two resilient mounting bodies, which are spaced apart along said crosspiece and secured to the latter and to said rigid structure, said mounting bodies providing a resilient connection between said crosspiece and said rigid structure, each of said mounting bodies having different stiffnesses in different directions in a generally horizontal plane; two wheel carriers, each of which carries one of said wheels; linking means linking said wheel carriers to said crosspiece at opposite ends thereof and permitting each of said wheel carriers to perform a vertical movement relative to said crosspiece; constraining means connected to said wheel carrers and to said rigid structure so as to constrain said wheel carriers to move in a generally vertical direction relative to said crosspiece and said rigid structure; hinge means provided with elastic liners and hingedly interconnecting parts of said assembly to each other and to said rigid structure; two diagonal struts hingedly connected by said hinge means to said crosspiece and to said rigid structure so that the longitudinal axes of said diagonal struts intersect to the rear of said assembly, said linking means associated with each of said wheel carriers comprising two lower transverse control arms, which have longitudinal axes intersecting at a point that is disposed on the outside of and axially spaced from the adjacent one of said wheels, and a longitudinal control arm hingedly connected by said hinge means to each of said wheel carriers and to said rigid structure. - View Dependent Claims (11, 12, 13, 14)
