摘要： An apparatus for use in turning steerable vehicle wheels includes first and second pumps driven by a vehicle engine to supply fluid under pressure to a power steering motor assembly connected with the vehicle wheels. The first pump is sized to provide a fluid flow required by the power steering motor assembly to effect a first vehicle maneuver when the engine speed is at or above a first predetermined speed corresponding to the vehicle cruising at highway speed. A valve directs fluid flow from the second pump to the power steering motor assembly, which when combined with the fluid flow of the first pump is sufficient for the power steering assembly to effect a second vehicle maneuver when the engine speed is at or above the first predetermined speed. A greater fluid flow is required to effect the second vehicle maneuver than to effect the first vehicle maneuver.

摘要： An improved ball joint for use in a motor vehicle steering or suspension system includes a housing, a bearing disposed in the housing, and a ball stud supported within the housing by the bearing. The bearing includes at least a first bearing member formed from a first material and a second bearing member formed from a second dampening material attached to at least a portion of an outer surface of the first bearing member. The first bearing member has a bidirectional slot formed therein which is configured to allow the ball stud to articulate in a first direction and restrict and dampen articulation in a second direction which is generally transverse to the first direction.

摘要： A gearbox assembly for an electric power steering apparatus comprises an input shaft which carries a worm gear and is supported relative to the housing at one end by a first bearing assembly and at the other by a second bearing assembly, an output shaft which carries a wheel gear which is fixed relative to a housing and which meshes with a worm gear on the input shaft, and a spring assembly which acts between the housing and the first bearing assembly, and the spring assembly applying a biasing force onto the second bearing in a first direction away from the neutral position so as to ensure that the worm and wheel are fully engaged. The spring assembly has a spring rate which has a step change about the neutral position such that the rate of change in the force exerted by the spring assembly on the second bearing assembly as the spring moves in the first direction from its neutral position is lower than the rate of change in the force as the spring moves in the second direction away from the neutral position.

摘要： A method of controlling a roll control system includes monitoring the position of a steering mechanism of a vehicle. A rate of change of the position of the steering mechanism is determined. The rate of change is compared to a change threshold value. The lateral acceleration of a vehicle is monitored. The lateral acceleration is compared to an acceleration threshold value. A roll control system having at least one of a front and a rear actuator is controlled based at least in part upon the comparisons of the rate of change of the steering mechanism to the change threshold value and the lateral acceleration to the acceleration threshold value. The front and rear actuators are controlled independently of each other depending upon the state of a vehicle stability index.
