  • Disconnecting stabilizer bar assembly having disconnect mechanism with reduced backlash
    Patent number: 11383576
    Abstract: A stabilizer bar assembly having a pair of bar members and a clutch assembly with a first and second couplers, which are fixedly coupled to the bar members, a coupling sleeve and a rotary lock. The coupling sleeve matingly engages the first coupler. The coupling sleeve is movable along an axis between a first position, in which the coupling sleeve is disengaged from the second coupler to permit relative rotation between the stabilizer bar members about the axis, and a second position in which the coupling sleeve is engaged to the first and second couplers. The rotary lock has lock members that are fixedly coupled to the coupling sleeve and the second coupler. The lock members engage one another when the coupling sleeve is in the second position to inhibit relative movement about the rotational axis between the coupling sleeve and the second coupler.
    Type: Grant
