Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
69 words
A motor vehicle drive line comprising, a differential gear unit having a differential pinion drive shaft, a companion flange surrounding the forward end of said pinion shaft, and a torsional vibration damper having an annular resilient member mounted on an axial end surface of said companion flange and an annular inertia member secured about said resilient member, said resilient member and said inertia member coaxially surrounding said companion flange.
Claim 2
Dependent Claim
69 words
A motor vehicle drive line comprising, a differential gear unit having a differential pinion drive shaft, a companion flange surrounding the forward end of said pinion shaft, and a torsional vibration damper having an annular resilient member mounted on an axial end surface of said companion flange and an annular inertia member secured about said resilient member, said resilient member and said inertia member coaxially surrounding said companion flange.
Claim 3
Dependent Claim
116 words
A motor vehicle drive line comprising, a differential gear unit having a differential pinion drive shaft, a companion flange surrounding the forward end of said drive shaft and having an annular shoulder formed by a radially extending portion and an axially extending portion, a resilient member having a radially extending flange portion and an axially extending sleeve portion, said flange portion and said sleeve portion respectively mounted on said radially extending portion and said axially extending portion of said annular shoulder, and an annular inertial member coaxially attached about said resilient member, the outer diameter of said annular inertia member being substantially equal to the outer diameter of said radially extending portion of the companion flange.
Claim 4
Dependent Claim
116 words
A motor vehicle drive line comprising, a differential gear unit having a differential pinion drive shaft, a companion flange surrounding the forward end of said drive shaft and having an annular shoulder formed by a radially extending portion and an axially extending portion, a resilient member having a radially extending flange portion and an axially extending sleeve portion, said flange portion and said sleeve portion respectively mounted on said radially extending portion and said axially extending portion of said annular shoulder, and an annular inertial member coaxially attached about said resilient member, the outer diameter of said annular inertia member being substantially equal to the outer diameter of said radially extending portion of the companion flange.
Claim 5
Dependent Claim
75 words
A motor vehicle drive line comprising, a differential gear unit having a differential pinion drive shaft, a companion flange surrounding the forward end of said drive shaft and having an annular shoulder, a resilient member of L-shaped cross-section co-axially attached to said annular shoulder of said companion flange, and an inertial ring member coaxially mounted about said resilient member, said inertia ring member compressing said resilient member against said annular shoulder of said companion flange.
Claim 6
Dependent Claim
75 words
A motor vehicle drive line comprising, a differential gear unit having a differential pinion drive shaft, a companion flange surrounding the forward end of said drive shaft and having an annular shoulder, a resilient member of L-shaped cross-section co-axially attached to said annular shoulder of said companion flange, and an inertial ring member coaxially mounted about said resilient member, said inertia ring member compressing said resilient member against said annular shoulder of said companion flange.
Claim 7
Dependent Claim
100 words
A motor vehicle drive line comprising, a differential gear unit having a differential pinion drive shaft, a companion flange surrounding the forward end of said pinion shaft and having an annular shoulder formed by a radially extending portion and an axially extending portion, a resilient member configured to extend along said radially extending portion and axially extending portion of the annular shoulder and attached thereto, and an inertia ring member coaxially mounted about said resilient member, the outer diameter of said annular inertia member being substantially equal to the outer diameter of said radially extending portion of the companion flange.
Claim 8
Dependent Claim
100 words
A motor vehicle drive line comprising, a differential gear unit having a differential pinion drive shaft, a companion flange surrounding the forward end of said pinion shaft and having an annular shoulder formed by a radially extending portion and an axially extending portion, a resilient member configured to extend along said radially extending portion and axially extending portion of the annular shoulder and attached thereto, and an inertia ring member coaxially mounted about said resilient member, the outer diameter of said annular inertia member being substantially equal to the outer diameter of said radially extending portion of the companion flange.
