摘要： A bearing isolator assembly comprises an inner support member, an outer support member, a resilient member, an elastomeric ring, and a support cap disposed over a bearing surface defined by the inner support member or the outer support member. A path of travel is defined between the inner support member and the outer support member. The resilient member is disposed between the inner support member and the outer support member and is configured to resist compression between the inner support member and the outer support member within a first portion of the path of travel. The outer support member defines a ring envelope, in which the elastomeric ring is disposed. The inner support member defines a ring compression surface, and the elastomeric ring is configured to resist compression between the ring compression surface of the inner support member and the ring compression surface of the outer support member within a second portion of the path of travel.

摘要： An adjustable steering column assembly having a repositionable steering column and a break-away lever arm. The lever arm has a first mounting interface and an adjustment assembly member operably coupled with the steering column has a second mounting interface. Engagement of the first and second mounting interfaces mounts the lever arm on the adjustment assembly member. Movement of the lever arm rotates the adjustment assembly member to facilitate the repositioning of the steering column. Applying a breakaway force exceeding a threshold value to the lever arm disengages the mounted lever arm from the adjustment assembly member by relative translational movement between the first and second mounting interfaces. Some embodiments employ a threaded fastener installed to a predetermined torque to bias the first and second mounting interfaces into engagement. The threaded fastener can be installed such that it may be non-frangibly disengaged by displacement through the open end of a slot.

摘要： A bearing assembly includes an inner race having a first inner race half and a second inner race half, and an outer race having a first outer race half and a second outer race. The first inner race half and the second inner race half cooperate to define an inner annular groove, and the first outer race half and the second outer race half cooperate to define an outer annular groove. A plurality of rollers is disposed within the inner annular groove and the outer annular groove in rolling engagement with the inner race and the outer race. An inner coupling mechanism couples the first inner race and the second inner race together, and an outer coupling mechanism couples the first outer race and the second outer race together.

摘要： A steering column assembly comprises an upper jacket, a lower jacket extending along a longitudinal axis, and a bushing apparatus disposed therebetween. The upper jacket and the lower jacket include a circular cross section. The bushing apparatus includes a first contact surface, a second contact surface and a third contact surface disposed radially about the longitudinal axis and equally spaced from each other. A compression device is coupled to one of the lower jacket and the upper jacket for applying a compressive force to the first contact surface. The second contact surface and the third contact surface resist the compressive force. The compression device is adjustable to vary a slip resistance between the bushing apparatus and one of the upper jacket and lower jacket.

摘要： An adjustable steering column assembly with a steering shaft extending through a jacket member. An elongate locking member extends through two opposed sidewalls and a compression member positioned between the sidewalls. One of either the sidewalls or the compression member is fixed relative to the jacket member while the other is fixed relative to the vehicle structure. Spacers are located on opposite sides of the compression member between the compression member and the two sidewalls. First and second abutment surfaces are engaged with outward facing surfaces of the sidewalls and are coupled to the elongate locking member. An actuator assembly moves the locking assembly between unlocked and locked positions. In the locked position, the abutment surfaces bias the sidewalls inwardly to firmly engage the compression member between the spacers.
