Abstract
Abstract An independent front wheel suspension for motor vehicles has a support strut which includes a telescopic shock absorber and an enclosed coil spring which serves as the wheel spring. The piston rod of the telescopic shock absorber either alone or together with an upper wheel spring plate is resiliently supported at the vehicle body by a mounting arrangement having an annular elastomeric element. Several coupled and decoupled designs of mounting arrangements are disclosed. Each of the arrangements is characterized by an annular elastomeric element having a substantially axially aligned recess means in at least one of its two end faces for improved cardanic movability.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
121 words
In a mounting arrangement for an independent front wheel suspension for motor vehicles, having a support strut including a telescopic shock absorber and a coiled spring enclosing the latter, and serving as a wheel spring, wherein an end of the piston rod of the telescopic shock absorber, either alone or together with an upper wheel spring plate, is resiliently supported at the vehicle body by an annular elastomeric element of the mounting arrangement, the improvement comprising: said annular elastomeric element having substantially axially aligned recess means in at least one of its two end faces for improved cardanic movability, said axially aligned recess means being approximately slot shaped in section and of expanded shape at the interior of the elastomeric element.
Claim 2
Dependent Claim
121 words
In a mounting arrangement for an independent front wheel suspension for motor vehicles, having a support strut including a telescopic shock absorber and a coiled spring enclosing the latter, and serving as a wheel spring, wherein an end of the piston rod of the telescopic shock absorber, either alone or together with an upper wheel spring plate, is resiliently supported at the vehicle body by an annular elastomeric element of the mounting arrangement, the improvement comprising: said annular elastomeric element having substantially axially aligned recess means in at least one of its two end faces for improved cardanic movability, said axially aligned recess means being approximately slot shaped in section and of expanded shape at the interior of the elastomeric element.
Claim 3
Dependent Claim
16 words
The improvement as defined in claim 1 wherein the recess means is a continuous annular slot.
Claim 4
Dependent Claim
18 words
The improvement as defined in claim 1 wherein the recess means is a plurality of circumferentially spaced cavities.
Claim 5
Dependent Claim
115 words
In a mounting arrangement for an independent front wheel suspension for motor vehicles, having a support strut including a telescopic shock absorber and a coiled spring enclosing the latter, and serving as a wheel spring, wherein an end of the piston rod of the telescopic shock absorber, either alone or together with an upper wheel spring plate, is resiliently supported at the vehicle body by an annular elastomeric element, the improvement comprising: said annular elastomeric element having substantially axially aligned recess means in each of its two end faces for improved cardanic movability, said axially aligned recess means being approximately slot shaped in section and of expanded shape at the interior of the elastomeric element.
Claim 6
Dependent Claim
115 words
In a mounting arrangement for an independent front wheel suspension for motor vehicles, having a support strut including a telescopic shock absorber and a coiled spring enclosing the latter, and serving as a wheel spring, wherein an end of the piston rod of the telescopic shock absorber, either alone or together with an upper wheel spring plate, is resiliently supported at the vehicle body by an annular elastomeric element, the improvement comprising: said annular elastomeric element having substantially axially aligned recess means in each of its two end faces for improved cardanic movability, said axially aligned recess means being approximately slot shaped in section and of expanded shape at the interior of the elastomeric element.
Claim 7
Dependent Claim
23 words
The improvement as defined in claim 4 wherein the recess means are enveloped by a textile or wire fabric within the elastomeric element.
Claim 8
Dependent Claim
43 words
The improvement as defined in claim 4 wherein the elastomeric element is disposed in a two part housing and wherein the upper wheel spring plate has an inner upwardly bent portion which forms the outer part of the housing enclosing the elastomeric element.
Claim 9
Dependent Claim
26 words
