Abstract
An element forming a suspension joint and torsion spring, characterized in that it comprises an outer tubular sub-frame, an inner tubular sub-frame and an intermediate connecting sleeve made from an elastomer material which is joined without any possible slippage of the outer and inner sub-frames; said elastomer sleeve comprises at least two cell structures extending along the circumference thereof, whereby the radial rigidity of the joint is reduced in a significant manner in at least a number of directions without significantly reducing the torsional rigidity thereof.
Claims14
A suspension joint and torsion spring assembly, characterized in that it comprises an outer tubular subshell, an inner tubular subshell and an intermediate coupling sleeve made of elastomer, secured with no possibility to slide to the outer and inner subshells;
- said elastomeric sleeve comprising at least two cells extending along its circumference;
- so that the radial spring rate of the joint is significantly reduced in at least some directions without its torsional spring rate being significantly reduced.
