Abstract: A steering column (10) includes a support (24) through which a steering column member (12) extends connected with a mounting bracket (68). A locking mechanism (130) locks the support (24) in any one of a plurality of positions relative to the mounting bracket (68). The locking mechanism (130) has a locking shaft (200) extending through first and second cams (148, 132) and the mounting bracket (68). The first cam (148) is rotatable relative to the locking shaft (200) and the second cam (132) and has a first cam surface (150). The second cam (132) has a second cam surface (134) facing the first cam surface (150). A bearing (166) includes a flexible cage (168) and a plurality of bearing members (170) rotatable relative to the cage engaging the first and second cam surfaces (150, 134). The locking mechanism (130) clamps the support (24) to the mounting bracket (68) when the first cam (148) is in a first position relative to the second cam (132). The support (24) is movable relative to the mounting bracket (68) and the locking shaft (200) is prevented from moving relative to the mounting bracket when the first cam (148) is in a second position relative to the second cam (132).

Abstract: A steering column (10) includes a steering column member (12). A mounting bracket (66) connects the steering column (10) to a vehicle frame. The mounting bracket (66) has a surface defining an aperture (77). A support (24), through which the steering column member (12) extends, is connected with the mounting bracket (66). The support (24) supports the steering column member (12) for rotation about a longitudinal axis (26) of the steering column member (12) and is movable relative to the mounting bracket. A locking mechanism (130) prevents movement of the support (24) relative to the mounting bracket (66). A first portion (42) is connected with the support (24) and is movable with the support (24) and the steering column member (12) relative to the mounting bracket (66). A follower pin (63) extends from the first portion (42) and into the aperture (77) in the mounting bracket (66). The follower pin (63) engages the surface defining the aperture (77) to limit movement of the steering column member (12) relative to the mounting bracket (66). The follower pin (63) is spaced apart from the locking mechanism (130).

Abstract: A steering column (10, 210) includes a steering column member (12, 212) and a support (24, 224) which supports the steering column member for rotation about a longitudinal axis (26, 226) of the steering column member. A mounting bracket (50, 266) connects the steering column (10, 210) to a vehicle frame. A pair of arms (66, 68 and 276, 278) interconnects the support (24, 224) and the mounting bracket (50, 266). Each of the arms (66, 68 and 276, 278) has an end (72, 78 and 296, 304) pivotally connected with the mounting bracket (50, 266) and an end (88, 98 and 310, 318) pivotally connected with the support (24, 224). A locking mechanism (108, 330) locks the arms (66, 68 and 276, 278) in any one of a plurality of pivot positions relative to the mounting bracket (50, 266) and locks the support (24, 224) in any one of a plurality of pivot positions relative to the arms. The locking mechanism (108, 330) includes a locking shaft (110, 340) extending through the mounting bracket (50, 266), one of the arms (66, 68 and 276, 278), and into the support (24, 224). The locking shaft (110,340) extends through the one arm (66, 68, and 276, 278) at a location between the ends of the arm.

Abstract: A steering system (10) for a vehicle (16) comprises a housing (20) having first and second end portions (32, 34) and an intermediate portion (50). A steering member (66) is supported for axial movement in the housing (20). A piston (100) fixed for movement with the steering member (66) has opposite end faces (104, 106). First and second springs (130, 132) engage the end faces (104, 106) of the piston (100) and bias the piston and thereby the steering member (66) in first and second axial directions toward a straight ahead position. Steering linkage (124, 126) connected with the piston member (100) transmits movement of the piston member (100) to steerable wheels (12, 14) of the vehicle.

Abstract: An apparatus that mounts a steering shaft connectable with a steering wheel and rotatable to turn steerable vehicle wheels to a vehicle includes a support member connectable with the vehicle. The support member has first and second bearing housings spaced from each other along a longitudinal axis of the steering shaft. Each of the first and second bearing housings has a surface extending parallel to the longitudinal axis with an opening through which bearings are inserted that support the steering shaft for rotation relative to the support member.
