摘要： A variable effort automotive power steering gear including an input or stub shaft, an output shaft or pinion head, a torsion bar between the stub shaft and pinion head defining an open-center position of one relative to the other, and detent reaction apparatus between the stub shaft and pinion head. The detent reaction apparatus includes a radial socket in a cylindrical wall of the pinion head, a detent groove in a stem of the stub shaft in the cylindrical wall, an insert rotatably supported in the radial socket with an eccentric bore offset from the centerline of the radial socket, and a detent element slidably supported in the eccentric bore in the insert and having a spherical end adapted to seat in the detent groove. The spherical end of the detent element is centered in the detent groove by rotating the insert until the detent element is at an innermost radial position. The adjusted position of the insert is captured by an in-situ injection molded plastic retainer on the pinion head in a wide annular groove in an outside diameter of the cylindrical wall which engages an exposed cavity on the insert. The retainer has a pair of annular end walls facing in spaced relationship a pair of annular shoulders on the pinion head which form the sides of the wide annular groove. The annular shoulders and annular end walls cooperate in defining a pair of seal ring grooves on the pinion head.

摘要： A steering column assembly includes a column jacket adjustable along a longitudinal axis and collapsible along the longitudinal axis in response to a collision event. A compression bracket is mounted to the column jacket and defines a telescope slot having an adjustment portion and a continuation portion. A shaft extends through the telescope slot with the column jacket and the compression bracket moveable relative to the shaft during adjustment and collapse of the steering column assembly. A stop is detachably coupled to the compression bracket and partially covers the telescope slot to prevent movement of the shaft into the continuation portion during adjustment. The stop detaches during collapse to permit the shaft into the continuation portion. A lever rotates with the shaft and includes a tab for engaging the stop when the lever is in an unlocked position to prevent detachment of the stop during adjustment.

摘要： A steering column assembly includes a column jacket having a jacket portion and a compression bracket attached thereto. The compression bracket includes a planar wall spaced from the column portion and a sidewall extending between the planar wall and the jacket portion. The sidewall defines a telescope slot extending along a longitudinal axis. A shaft extends through the telescope slot of the sidewall. A roller is supported on and rotatable about the shaft, and in rolling engagement with the planar wall. The roller positions the shaft within the telescope slot to prevent sliding frictional engagement between the shaft and the sidewall. The rolling coefficient of friction between the roller and the planar wall is less than the sliding coefficient of friction between the shaft and the sidewall to reduce a frictional load produced during longitudinal collapse of the steering column assembly.

摘要： A rotating cable device preferably for use in a steering column assembly couples a drive member to a driven member of the assembly for rotation and without any lost motion or release of unwanted absorbed energy, which could potentially create inefficiencies in operation and undesirable noise. A rigid sheath of the device extends along a non-linear centerline and a resilient tube preferably extends through the sheath. A flexible cable of the device extends through the tube and couples between the members for rotation. The cable device enables versatility in the arrangement and orientation of the drive and driven members in a variety of different steering column and transmission shift mount applications for vehicles.
