Abstract
Abstract A stabilizing device for a vehicle suspension of an automotive vehicle. The stabilizing device is capable of stabilizing the vehicle and of absorbing shock exerted in any direction. The stabilizing device comprises a first and a second shock absorbing member. The first shock absorbing member is applied to the vehicle as a vehicle suspension which is disposed between the vehicle body or chassis and a suspension member. The second shock absorbing member is provided on the vehicle so that it indirectly absorbs a shock exerted on the vehicle. The second shock absorber provides a restoring force approximate ten times more than that of the first shock absorbing member. Further, the second shock absorbing member has a titled position so that it can absorb a force or shock exerted on the vehicle in forward, backward and lateral directions.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
127 words
A device for stabilizing the suspension system of an automotive vehicle comprising: first shock absorbing means substantially vertically interposed between the vehicle body and the axle housing, said first shock absorbing means being compressed and expanded in response to generally vertical road shocks; a pair of lower control arms disposed adjacent both ends of the axle housing and extending normally with respect thereto for mounting the axle housing below the vehicle body; and second shock absorbing means non-vertically interposed between the axle housing and said pair of lower control arms, said second shock absorbing means being compressed and expanded in response to generally non-vertical as well as vertical shocks, said second shock absorbing means having a greater absorbing and stabilizing power than said first shock absorbing means.
Claim 2
Independent Claim
127 words
A device for stabilizing the suspension system of an automotive vehicle comprising: first shock absorbing means substantially vertically interposed between the vehicle body and the axle housing, said first shock absorbing means being compressed and expanded in response to generally vertical road shocks; a pair of lower control arms disposed adjacent both ends of the axle housing and extending normally with respect thereto for mounting the axle housing below the vehicle body; and second shock absorbing means non-vertically interposed between the axle housing and said pair of lower control arms, said second shock absorbing means being compressed and expanded in response to generally non-vertical as well as vertical shocks, said second shock absorbing means having a greater absorbing and stabilizing power than said first shock absorbing means.
Claim 3
Dependent Claim
40 words
A device, as claimed in claim 1, further having a pair of upper control arms, each said arm being connected at one of its ends to the axle housing and at the other of its ends to the vehicle body.
Claim 4
Dependent Claim
25 words
A device, as claimed in claim 2, wherein said second shock absorbing means is interposed between said lower control arms and said upper control arms.
Claim 5
Dependent Claim
24 words
A device, as claimed in claim 2, wherein said second shock absorbing means is interposed between the axle housing and said upper control arms.
Claim 6
Dependent Claim
43 words
A device as claimed in claim 1 or 2, further having bracket means affixed to the axle housing, said bracket means being connected to the lower end of said first shock absorbing means and the rear end of said second shock absorbing means.
Claim 7
Dependent Claim
35 words
A device as claimed in claim 1 or 2, wherein said second shock absorbing means is disposed in a position which is tilted from the vertical and tilted from the main axis of the vehicle.
Claim 8
Independent Claim
