Abstract:
A vehicle suspension with power adjustable torsion bar trim height adjustment, said suspension comprising:a torsion bar connected at one end to a wheel attachable support to form a torsional load carrying spring element for supporting a vehicle; a body portion spaced from said support and supporting a second end of the torsion bar; a torsion member connected to said second end of the torsion bar and oscillatable therewith to vary the torque setting of the torsion bar wherein the torsion member is a lever pivotally movable with said second end of the torsion bar; an actuator acting between said body portion and said torsion member and operable to oscillate the torsion member between at least two operating positions having differing torque settings to vary the trim height of the vehicle suspension; a power source connected to operate the actuator upon command to oscillate the torsion member between said operating positions and thereby raise or lower the running height of the vehicle; and a lock pivotally mounted on said body portion and having notches and wherein said lever further includes a lock protrusion operatively engageable with said notches of said lock to lock the lever in at least one of said operating positions upon deactivation of the power source.
