Abstract: A strut for a vehicle suspension includes a hydraulic cylinder housing defining a hydraulic fluid chamber. The hydraulic cylinder includes an air passage adjacent to the chamber and separated therefrom by a first common wall. An air spring is supported on an upper portion of the cylinder housing in fluid communication with the air passage. An air reservoir extends from a portion of the cylinder housing and is in fluid communication with and fluidly connected to the air spring by the air passage. The air reservoir and the chamber are separated by a second common wall. The air reservoir preferably forms at least a portion of the knuckle, which supports the wheel end. In this manner, the knuckle and hydraulic cylinder are preferably integrated into one structure, preferably by a single cast unit. The integrated air reservoir and air passage reduces the size of the air spring and eliminates the need for a remote air chamber and associated hoses and fittings.

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.

Abstract: A suspension assembly for a motor vehicle includes upper and lower control arms pivotally attached to a frame member of the vehicle. A knuckle arm pivotally attaches to the upper and lower control arms moves along a substantially vertical axis in response to wheel movement caused by an uneven road surface. An actuation link is attached to one of the control arms at one end and to a damper assembly at another end. The damper assembly is disposed substantially within the frame member along a second axis transverse to vertical movement of the wheel and is actuated along the transverse axis in response movement of the control arm along the substantially vertical axis.

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.

Abstract: A piston assembly for a monotube shock absorber includes a piston body with a non-symmetrical outer band that provides a bearing surface against a shock tube wall. The outer band defines a first diameter that is a maximum outer diameter of the piston assembly. The piston body also includes an outer surface portion that is defined by a second diameter less than the first diameter, and which comprises a non-contact surface. The outer band extends in a serpentine manner about an outer circumference of the piston body such that recesses are formed between the shock tube wall and the non-contact surface. Side ports are located within these recesses to allow a blow-off area to be increased by incorporating annular lands into the piston assembly.

Abstract: A variable rate bushing passively controls the stiffness of a stabilizer bar. During normal vehicle operation, the stabilizer bar is compliant. As twist increase, the resistance increases. In one embodiment, the variable rate bushing includes at least one void which compresses as the vehicle turns. As the stabilizer bar axially twists, the void compresses and the rate of the bushing increases, reducing axial twist and increasing stiffness of the stabilizer bar. In one embodiment, the voids are teardrop shaped, arc shaped, or bone shaped. Alternatively, the bushing includes an inner layer of softer material and an outer layer of harder material to control stabilizer bar stiffness. Also, the bushing may include a molded insert made of a hard material inserted into a softer material to control the stiffness of the stabilizer bar.

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.

Abstract: A steering assembly is provided for a vehicle including an upper connection, typically provided by an upper control arm. A knuckle includes an upper and lower portions with the upper portion supported by the upper connection. A lower assembly of the present invention includes a control arm with legs extending from a spring portion at spaced apart ends. The legs extend from its ends and converge to a lower connection for supporting the lower portion of the knuckle with the upper and lower connections defining a wheel camber and a wheel caster. Preferably, each of the legs of the control arm has a different spring rate to provide a change in wheel camber under the deflection of the control arm during wheel travel. The different spring rates of the legs permits the lower connection to twist thereby enabling the wheel caster to change slightly during the upward and downward motion of the wheel.

Abstract: A vehicle suspension is provided that includes a frame supporting a pair of laterally spaced apart suspension members pivotally supported on the frame and movable in a vertical direction. A pair of wheel ends is each supported respectively on one of the suspension members. A stabilizer bar is supported on the frame laterally between the suspension members. The stabilizer bar includes opposing ends each respectively proximate to one of the suspension members. A pair of resilient stabilizer bar links each respectively interconnect one of the ends and one of the suspension members and transmit torsional force to the stabilizer bar in response to movement of the suspension members in the vertical direction during roll conditions. The links have first and second deflection rates during the roll condition with the first rate being less than the second deflection rate. The links transition from the first deflection rate to the second deflection rate and from the second deflection rate to an effective zero deflection rate.

Abstract: An intervehicle network provides for communicating information regarding driving conditions experienced by one vehicle to another remotely located vehicle. By receiving information regarding oncoming driving conditions, the vehicle driver may take action to anticipate the driving condition and avoid potential hazards or inconveniences. Additionally, for vehicles having onboard dynamically adjustable systems, an electronic controller may adjust the performance of the adjustable system responsive to the driving condition information received before the vehicle reaches the location of the driving condition. Another feature of a system designed according to this invention is to have onboard diagnostics where the controller monitors one or more variables to detect when one or more vehicle components are showing signs of aging or wear. Communications between vehicles in a system designed according to this invention may be directly between the vehicles or through a central information communication module.
