Abstract
An independent suspension for a motor vehicle includes a wheel carrier with a spindle for rotatably mounting a road wheel, a telescoping strut having a lower end rigidly attached to the wheel carrier and an upper end attached to the chassis of the motor vehicle. A control arm is interposed between the wheel carrier and the chassis, and a torsional unloading device is interposed between the control arm and the telescoping strut such that the torsional unloading device will impose a force upon the telescoping strut tending to counteract an opposing bending moment imposed upon the strut by the wheel carrier.
Claims16
An independent suspension for a motor vehicle comprising:
- a wheel carrier including a spindle for rotatably mounting a road wheel;
- a telescoping strut having a lower end rigidly attached to said wheel carrier and an upper end attached to the chassis of said motor vehicle;
- a control arm interposed between said wheel carrier and said chassis;
- and
- a torsional unloading device comprising a torsion spring interposed between said control arm and said telescoping strut such that said torsional unloading device will impose a force upon said telescoping strut tending to counteract an opposing bending moment imposed upon said strut by said wheel carrier.
An independent suspension for a motor vehicle comprising:
- a wheel carrier including a spindle for rotatably mounting a road wheel;
- a telescoping strut having a lower end rigidly attached to said wheel carrier and an upper end attached to the chassis of said motor vehicle;
- a control arm interposed between said wheel carrier and said chassis;
- and
- a torsional unloading device comprising an elastomeric element, interposed between said control arm and said telescoping strut such that said torsional unloading device will impose a force upon said telescoping strut tending to counteract an opposing bending moment imposed upon said strut by said wheel carrier.
An independent suspension for a motor vehicle comprising:
- a wheel carrier including a spindle for rotatably mounting a road wheel;
- a telescoping strut having a lower end rigidly attached to said wheel carrier and an upper end attached to the chassis of said motor vehicle;
- front and rear generally transverse control arms pivotally attached to said wheel carrier and said chassis;
- and
- a torsion spring comprising two coiled segments with each of said segments having a first end mounted between said control arms and a second end operatively connected with said telescoping strut such that said spring will impose a force upon said telescoping strut tending to counteract an opposing bending moment imposed upon said strut by said wheel carrier.
