Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
110 words
A rear assembly for an automotive vehicle, having independent wheels and trailing suspension arms each wheel being mounted on a journal fixed to a suspension arm, wherein each suspension arm is integral with or fixed to a shaft member extending essentially transversely with respect to the longitudinal axis of the vehicle, said shaft members being substantially coaxial, and being respectively connected at their outer ends located out of said suspension arms to the suspended part of the vehicle and being supported one by the other at their respective inner ends, means being provided between said shift members for allowing a relative angular movement of said shafts about their common axis.
Claim 2
Dependent Claim
110 words
A rear assembly for an automotive vehicle, having independent wheels and trailing suspension arms each wheel being mounted on a journal fixed to a suspension arm, wherein each suspension arm is integral with or fixed to a shaft member extending essentially transversely with respect to the longitudinal axis of the vehicle, said shaft members being substantially coaxial, and being respectively connected at their outer ends located out of said suspension arms to the suspended part of the vehicle and being supported one by the other at their respective inner ends, means being provided between said shift members for allowing a relative angular movement of said shafts about their common axis.
Claim 3
Dependent Claim
47 words
A rear assembly as claimed in claim 1, comprising spring return means provided between the two shaft members, said spring return means being adapted to exert a reaction torque between the two shaft members when said shaft members undergo a relative rotation movement about their common axis.
Claim 4
Dependent Claim
42 words
A rear assembly as claimed in claim 2, wherein said spring return means comprises two bushings of elastomer, each bonded to two rigid sleeves fitted respectively to the two shaft members, a tubular spacer element being provided between the two outer sleeves.
Claim 5
Dependent Claim
43 words
A rear assembly as claimed in claim 1, wherein one of said shaft members is tubular and surrounds the other of said shafts over an overlapping area, bearing means being provided between the shaft members, respectively adjacent the ends of said overlapping area.
Claim 6
Dependent Claim
18 words
A rear assembly as claimed in claim 4, wherein said bearing means comprises bushings made of antifriction material.
Claim 7
Dependent Claim
17 words
A rear assembly as claimed in claim 4, wherein said bearing means comprises ball or needle bearings.
Claim 8
Dependent Claim
48 words
A rear assembly as claimed in claim 1, wherein the outer end of each shaft member is connected to the suspended part of the vehicle by an elastic joint having a greater stiffness in the transverse direction of the vehicle than in the longitudinal direction of the vehicle.
Claim 9
Dependent Claim
51 words
A rear assembly as claimed in claim 1, wherein one of said shaft members is tubular and surrounds the other of said shaft members over an overlapping area, a radial clearance being defined between said shaft members and bearing means being provided therebetween respectively adjacent the ends of said overlapping area.
Claim 10
Dependent Claim
110 words
A rear assembly for an automotive vehicle, having independent wheels and trailing suspension arms, each wheel being mounted on a journal fixed to a suspension arm, wherein each suspension arm is integral with or fixed to a shaft member extending essentially transversely with respect to the longitudinal axis of the vehicle, said shaft members being substantially coaxial, and being respectively connected at their outer ends located out of said suspension arms to the suspended part of the vehicle and being supported one by the other at their respective inner ends, means being provided between said shift members for allowing a relative angular movement of paid shafts about their common axis.
Claim 11
Dependent Claim
110 words
A rear assembly for an automotive vehicle, having independent wheels and trailing suspension arms, each wheel being mounted on a journal fixed to a suspension arm, wherein each suspension arm is integral with or fixed to a shaft member extending essentially transversely with respect to the longitudinal axis of the vehicle, said shaft members being substantially coaxial, and being respectively connected at their outer ends located out of said suspension arms to the suspended part of the vehicle and being supported one by the other at their respective inner ends, means being provided between said shift members for allowing a relative angular movement of paid shafts about their common axis.
Claim 12
Dependent Claim
46 words
A vehicle as claimed in claim 9, comprising spring return means provided between the two shaft members, said spring return means being adapted to exert a reaction torque between the two shaft members when said shaft members undergo a relative rotation movement about their common axis.
Claim 13
Dependent Claim
41 words
A vehicle as claimed in claim 10, wherein said spring return means comprises two bushings of elastomer, each bonded to two rigid sleeves fitted respectively to the two shaft members, a tubular spacer element being provided between tHe two outer sleeves.
Claim 14
Dependent Claim
42 words
A vehicle as claimed in claim 11, wherein one of said shaft members is tubular and surrounds the other of said shafts over an overlapping area, bearing means being provided between the shaft members, respectively adjacent the ends of said overlapping area.
Claim 15
Dependent Claim
17 words
A vehicle as claimed in claim 12, wherein said bearing means comprises bushings made of antifriction material.
Claim 16
Dependent Claim
16 words
A vehicle as claimed in claim 13, wherein said bearing means comprises ball or needle bearings.
Claim 17
Dependent Claim
47 words
