摘要: A system for steering the wheels of a vehicle. The system includes a steering gear provided with a steering rack reciprocable in a power cylinder. A steering shaft has a pinion meshing with the steering rack. A hydraulic fluid system assists the reciprocation of the steering rack. The hydraulic fluid system includes a power piston reciprocable in the power cylinder. A control valve directs hydraulic fluid from a pump to the power cylinder at one side or the other of the piston, depending on the direction of rotation of the steering shaft. A lock valve is operable when closed to lock the rack against reciprocation to prevent steering of the wheels by preventing fluid flow in the hydraulic fluid system. The lock valve is controlled by a solenoid-operated electronic controller.

摘要: A retainer for preventing dislodgment of a shaft from a bearing including a radially expandable retaining ring, a circumferential groove in the shaft having a frustoconical side, and a frustoconical sidewall on an inner race of the bearing facing the frustoconical side of the groove in the shaft and cooperating therewith in defining an annular V-shaped retaining ring groove. In a seated position of the retaining ring in the retaining ring groove, the retaining ring is wedged between the frustoconical sidewall of the bearing inner race and the frustoconical side of the groove in the shaft to eliminate lash between the shaft and the bearing. To prevent the retaining ring from being squeezed out of the V-shaped retaining ring groove by a force on the shaft in the direction of its longitudinal centerline, the angle of convergence between the sides of the V-shaped retaining ring groove is selected from a range of angles whose tangent is less than the static coefficient of friction between the retaining ring, the frustoconical sidewall of the bearing inner race, and the frustoconical side of the groove in the shaft.

摘要: A vehicle steering column has a rake adjustment mechanism which includes a rake bracket having a rake slot provided with rake slot teeth. A tooth lock is supported in the rake slot with teeth opposing the rake slot teeth. A rake bolt is rotatable to a first rotative position to move the tooth lock to a retracted position with the teeth of the tooth lock out of engagement with the rake slot teeth. The bolt is axially rotatable to a second rotative position permitting the tooth lock to be moved to a locking position by a spring in which the teeth of the tooth lock engage the rake slot teeth. The bolt, when in the second rotative position, is movable, in response to an application of an impact force on the steering column to collapse the steering column, into bearing engagement with the tooth lock to positively retain the tooth lock in the locking position. The steering column is also provided with a release mechanism having shear pins and an energy absorption mechanism.

摘要: An energy absorber for a motor vehicle steering column including a yoke pivotable about a lateral centerline of a body of the motor vehicle and an energy absorbing mechanism responsive to linear translation of a mast jacket of the steering column relative to the yoke. The mast jacket extends through a bore in the yoke and a plastic bushing in the bore prevents the mast jacket from tipping relative to the yoke. The energy absorbing mechanism includes flat metal strap wound into a spiral coil and cradled or otherwise captured in a flat recess in the yoke tangent to the mast jacket. A distal end of the flat metal strap parallel to the mast jacket is rigidly attached to the latter so that during linear translation of the mast jacket under impact, the distal end is pulled out of the flat recess and unrolls the spiral coil. As the spiral coil unrolls, the flat metal strap is plastically deformed to convert into work a fraction of the kinetic energy of the impact on the steering column.

摘要: A tilt-adjustable motor vehicle steering column including a stationary mast jacket, a tilt housing supported on the mast jacket for up and down pivotal movement, an articulated steering shaft having a lower portion rotatably supported on the mast jacket and an upper portion rotatably supported on the tilt housing, a steering hand wheel on the upper portion of the steering shaft, and a balance spring preloaded in compression flexure between an inboard spring seat on the mast jacket and an outboard spring seat on the tilt housing. The tilt housing has a spring bore therein facing the inboard spring seat. The outboard spring seat is a screw thread in the spring bore defined by a raised boss in the spring bore. The balance spring is a helical coil spring having a helix angle matching the screw thread in the spring bore. Rotation of the balance spring in the spring bore advances an inboard end of the balance spring toward the inboard spring seat. After the inboard end of the balance spring engages the inboard spring seat, continued rotation of the balance spring preloads the latter in compression flexure between the inboard and the outboard spring seats.

摘要: A connection between a collapsible mast jacket of an energy absorbing steering column and a body of a motor vehicle including a mounting bracket on the mast jacket having an attachment flange perpendicular to a longitudinal centerline of the steering column, an aperture in the attachment flange, a plastic bushing captured in the aperture, and a fastener operative to rigidly clamp the plastic bushing to the body of the motor vehicle. The plastic bushing fractures in response to an impact on the steering column to release the mounting bracket. In a preferred embodiment, retention between the attachment flange and the plastic bushing is effected by an edge of the aperture in the attachment flange seated in an annular outside groove in the plastic bushing. A plurality of linear slots in the plastic bushing divide the plastic bushing into a plurality of cantilever spring segments which flex inward when the bushing is pushed into the aperture in the attachment flange and which snap out when the annular slot in the bushing registers with the peripheral edge of the aperture in the attachment flange.

摘要: A connection between a collapsible mast jacket of an energy-absorbing steering column and a body of a motor vehicle including an outboard mounting bracket on the mast jacket having a pair of lateral flanges, a pair of open slots in the lateral flanges each having a pair of side edges interrupted by a plurality of evenly-spaced notches, a pair of capsules in the open slots rigidly clamped to the vehicle body, and a plurality of equally-spaced plastic shear pins on the capsules seated in the notches to couple the capsules to the outboard mounting bracket. Each capsule includes a capsule base having the plastic pins thereon and a separate capsule cover. The linear pitch between the plastic shear pins is the same as the linear pitch between the notches. The magnitude of the force reaction between the outboard mounting bracket and the capsules required to separate the mounting bracket from the capsules and release the mast jacket for energy-absorbing linear collapse is adjusted by varying the longitudinal overlap between the capsules and the open slots in increments equal to the linear pitches between the plastic shear pins and between the notches.

摘要: The lower bracket assembly for a vehicle steering column includes a lower column support bracket with a central passage. A lower bearing adapter slides into the central passage from the rear. A pair of energy absorption straps engage the column support bracket and the lower bearing adapter and resist further forward movement of the lower bearing adapter. During a collision, the energy absorption straps absorb energy while permitting the lower bearing adapter to move forward and out of the central passage through the column support bracket.
