Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
211 words
A vehicle suspension device, for interposition between a vehicle body and an unsuspended part of a vehicle, comprising a coil spring, a damper within said spring, first elastically yieldable connecting means for connecting an upper end of said spring to the body of the vehicle, second elastically yieldable connecting means for connecting an upper end of said damper to the body of the vehicle, and third means for connecting lower ends of said spring and said damper to said unsuspended part of the vehicle, said first and second means being different and such that said damper is connected to the body of the vehicle less rigidly than said spring, said first and second connecting means comprising a metal annular member, an outer annular element of elastomer and an inner annular element of elastomer, said annular elements being concentric and vulcanized to said metal annular member, a plate connected to said metal annular member, said spring having an upper end bearing against said plate, a metal bushing, said damper having a rod rigidly fixed to said bushing, said outer element of elastomer being externally vulcanized to a collar adapted to be rigidly secured to the body of the vehicle and said inner element of elastomer being internally vulcanized to said metal bushing.

A vehicle suspension device, for interposition between a vehicle body and an unsuspended part of a vehicle, comprising a coil spring, a damper within said spring, first elastically yieldable connecting means for connecting an upper end of said spring to the body of the vehicle, second elastically yieldable connecting means for connecting an upper end of said damper to the body of the vehicle, and third means for connecting lower ends of said spring and said damper to said unsuspended part of the vehicle, said first and second means being different and such that said damper is connected to the body of the vehicle less rigidly than said spring, said first and second connecting means comprising a metal annular member, an outer annular element of elastomer and an inner annular element of elastomer, said annular elements being concentric and vulcanized to said metal annular member, a plate connected to said metal annular member, said spring having an upper end bearing against said plate, a metal bushing, said damper having a rod rigidly fixed to said bushing, said outer element of elastomer being externally vulcanized to a collar adapted to be rigidly secured to the body of the vehicle and said inner element of elastomer being internally vulcanized to said metal bushing.
Claim 3
Dependent Claim
17 words
A device as claimed in claim 1 wherein said plate bears directly against said metal annular member.
Claim 4
Dependent Claim
45 words
A device as claimed in claim 1, wherein said spring is rotatable relative to said collar, said plate being fixed to a metal ring rotatably mounted on said metal annular member, a thrust bearing being interposed between said metal ring and said metal annular member.
Claim 5
Dependent Claim
15 words
A device as claimed in claim 3, wherein said thrust bearing is a rolling bearing.
Claim 6
Dependent Claim
218 words
A vehicle comprising a body and unsprung parts, a suspension device interposed between the body and each unsprung part of the vehicle, said device comprising a coil spring, a damper within said spring, first elastically yieldable connecting means for connecting an upper end of said spring to the body of the vehicle, second elastically yieldable connecting means for connecting an upper end of said damper to the body of the vehicle, and third means for connecting lower ends of said spring and said damper to said unsuspended part of the vehicle, said first and second means being different and such that said damper is connected to the body of the vehicle less rigidly than said spring, said first and second connecting means comprising a metal annular member, an outer annular element of elastomer and an inner annular element of elastomer, said annular elements being concentric and vulcanized to said metal annular member, a plate connected to said metal annular member, said spring having an upper end bearing against said plate, a metal bushing, said damper having a rod rigidly fixed to said bushing, said outer element of elastomer being externally vulcanized to a collar adapted to be rigidly secured to the body of the vehicle and said inner element of elastomer being internally vulcanized to said metal bushing.
Claim 7
Dependent Claim
218 words
A vehicle comprising a body and unsprung parts, a suspension device interposed between the body and each unsprung part of the vehicle, said device comprising a coil spring, a damper within said spring, first elastically yieldable connecting means for connecting an upper end of said spring to the body of the vehicle, second elastically yieldable connecting means for connecting an upper end of said damper to the body of the vehicle, and third means for connecting lower ends of said spring and said damper to said unsuspended part of the vehicle, said first and second means being different and such that said damper is connected to the body of the vehicle less rigidly than said spring, said first and second connecting means comprising a metal annular member, an outer annular element of elastomer and an inner annular element of elastomer, said annular elements being concentric and vulcanized to said metal annular member, a plate connected to said metal annular member, said spring having an upper end bearing against said plate, a metal bushing, said damper having a rod rigidly fixed to said bushing, said outer element of elastomer being externally vulcanized to a collar adapted to be rigidly secured to the body of the vehicle and said inner element of elastomer being internally vulcanized to said metal bushing.
