Abstract:
1. A strut connectable between a wheel suspension component and the body of a motor vehicle, comprising: a shock absorber including a cylindrical member closed at one end connectable to said vehicle body, and a piston with a rod extending through an opening in the other end thereof, connectable to said suspension component; a first cylindrical sleeve member coaxially mounted on said cylindrical member, selectively rotatable by a motor mountable on said vehicle body; a second cylindrical sleeve member coaxially mounted on said first cylindrical sleeve member provided with a ball and screw connection therebetween, and an annular flange rigidly mounted coaxially therein; a first helical spring disposed coaxially relative to said shock absorber, having one end engaging said annular flange of said second cylindrical sleeve and an opposite end connectable to said suspension component; a second helical spring disposed coaxially relative to said shock absorber, having one end engaging said annular flange of said second cylindrical sleeve and an opposite end connectable to said vehicle body; and a third torsion spring disposed coaxially relative to said shock absorber, having an end connected to said second cylindrical sleeve member and an opposite end engageable by an abutment surface of said first cylindrical sleeve member upon axial displacement of said second cylindrical sleeve member toward an end of said first cylindrical sleeve member, effecting compression of said third torsion spring.
