  • Publication number: 20030111805
    Abstract: A housing attaches a stabilizer bar to the body of a vehicle and includes pin stops which actively control the stiffness of the stabilizer bar. A spring positioned about each of the pins provide a retaining spring force on the head of the pin, preventing the pins from moving into an aperture in the housing. When a sensor detects that lateral acceleration or yaw rate exceeds a threshold value, an actuator drives pins to overcome the spring force, pushing the pins into the aperture. When the pins are actuated, a protrusion on the stabilizer bar is trapped between the pins. When the vehicle turns and the stabilizer bar axially twists, the protrusion eventually contacts one the pins, preventing further rotation and stiffening the stabilizer bar.

  • Publication number: 20030111816
    Abstract: A clutch device for use with a vehicle suspension system to vary the stiffness of a stabilizer bar. A plurality of dampers connected to the clutch body alternate with a plurality of dampers connected to the stabilizer bar. The dampers are coated with a friction material and surrounded by a fluid. When a load is applied on the walls of clutch body, the friction material comes into contact, dampening the rotation action of the stabilizer bar. A sensor senses the parameters of the ride and generates a signal based on these parameters. The signal activates a power source controller which applies the load to the walls.

  • Publication number: 20030111806
    Abstract: An assembly for use as part of a vehicle suspension system includes an adjustable roll rate that is automatically adjusted responsive to maneuvers of the vehicle. A stiffener element is coupled with a stabilizer bar. The stiffener element increases the roll rate responsive to the vehicle wheels being turned. In one example, the stiffener element is a metallic plate that rotates into various positions responsive to the vehicle wheel being turned. The further the wheel turns, the further the plate rotates and the greater the increase in the roll rate.

  • Publication number: 20030111812
    Abstract: A suspension assembly for a vehicle is provided that includes a frame supporting upper and lower control arms in spaced relation to one another that are pivotally connected to the frame. A steering knuckle is supported between the control arms and supports a wheel. The orientation of the knuckle defines the wheel attitude, which includes caster, camber, toe, and track. The knuckle is rotated about its axis in response to mechanical inputs from a steering wheel. First and second actuators may be supported on one of the control arms and connected to a portion of the knuckle. A third actuator may be supported on the other control arm and connected to another portion of the knuckle. At least one sensor detects vehicle ride conditions such as braking, vehicle yaw, and steering position. A controller is connected to the sensors and the actuators to command the actuators to adjust at least one of the caster, camber, toe, and track in response to the vehicle ride conditions.

  • Publication number: 20030085542
    Abstract: A pair of tension cables are positioned around cams attached to the lower control arms of a vehicle suspension. Each tension cable includes a tension damper responsive to tension in the tension cables. Each tension damper includes a cylinder containing a fluid and a piston including at least one orifice attached to a rod. The piston divides the cylinder into a first and second compartment. The rod in connected to the tension cable. When the tension cable pulls on one end of the rod, the piston is pulled towards the tension cable. The fluid creates resistance in the tension damper as the fluid moves through the orifice from one compartment to the other compartment, damping vehicle roll. Control of the tension dampers can be passive, semi-active, or active.

  • Publication number: 20030070863
    Abstract: A steering system comprises a steering wheel and a feedback mechanism in communication with the steering wheel. A control unit communicates with a sensor and controls the feedback mechanism based on the signal from the sensor. The feedback mechanism may cause tactile feedback in the steering wheel. The feedback mechanism is most preferably incorporated by controlling a solenoid valve in a power steering circuit for the vehicle. By repeatedly actuating the solenoid valve, vibration can be caused in the steering wheel.

  • Publication number: 20030001355
    Abstract: A number of improved ways of connecting a slider to a trailer frame are disclosed. In one general type of solution, a wedge-shaped locking surface is formed on both the slider and the trailer. The wedged surfaces provide a very secure connection. In another general way of describing the embodiments, several of the embodiments have a plurality of locking surfaces which again provide a more secure connection.

  • Publication number: 20020130479
    Abstract: A mechanism is disclosed for controlling the vertical position of the transport trailer floor of a heavy trailer bearing vehicle having a pivoting air spring suspension system such that the transport trailer floor maintains a fixed position level to an adjacent dock platform when parked for loading or unloading. The mechanism comprises various embodiments of a locking system that disables the pivotal movement of selected pivoting suspension elements in any one of a plurality of possible fixed positions such that the transport trailer floor, when parked, resists downwardly imposed forces and maintains a fixed elevation equal to the elevation of an adjacent loading dock platform.

  • Publication number: 20020030341
    Abstract: A trailer slider pin control system is provided including a vehicle body and a rail supported along the body. The rails are moveable between a plurality of positions defined by a plurality of holes in the rail. A pin assembly is supported on the vehicle body and includes a pin moveable between unlocked and locked positions. The pin is disposed in the hole locking the rail to the vehicle body in the locked position. Conversely, the rail is free to move along the vehicle body in the unlock position. A sensor senses a location of a portion of the pin assembly, which corresponds to the unlock position. A vehicle speed control device, such as an engine, transmission, or braking system, is actuatable to limit the speed of the vehicle. A controller is connected to the sensor and the vehicle speed control device to actuate the vehicle speed control device to limit the speed of the vehicle in response to the sensors sensing the unlocked position.

  • Patent number: 6233837
    Abstract: An axle alignment system includes a transmitter, reflectors, and an indicator area. The transmitter transmits signals, preferably laser beams, to each reflector. Signals received by the reflectors attached to the end of the axles are reflected at a predetermined angle and direction to be viewed on an indicator area. The indicator area receives the redirected signals from each reflector and provides a visual illustration of the relationship between the suspension axle and another suspension part such as the suspension subframe siderails. Accordingly, the angularity of the axles relative to the siderails may be adjusted such that each of the reflected signals are displayed simultaneously on a reference marker. Once the reflected signals are aligned with respect to the reference marker, the axles are assured to be in accurate alignment.
