摘要： 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.

摘要： 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.

摘要： 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.

摘要： An adaptive suspension system for a motor vehicle varies suspension parameters in response to steering input. The system includes a sensor to measure changes in the power assist steering mechanism that indicate a change in vehicle direction and a shock variable suspension member changed in response to a change in vehicle direction. The sensor measures pressure changes in the power assist steering system such that the suspension system is optimized to accommodate specific vehicle maneuvering. In another embodiment, the variable suspension member is in hydraulic communication with the hydraulic circuit of the power assist steering mechanism such that pressure changes caused by steering input triggers changes in the suspension system to accommodate vehicle maneuvering.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A tandem axle suspension assembly includes a pair of walking beams disposed substantially parallel to a vehicle longitudinal axis supporting first and second axles. A link plate is pivotally attached to each of the walking beams and is pivotal about an axis transverse to the longitudinal axis. A first and a second link include pivotal connections between the link plate and a vehicle frame member. Vertical movement of the walking beams causes a corresponding rotation of the link plate to compensate for longitudinal displacement of the pivotal links with the first and second links and minimize longitudinal displacement of the walking beams.

摘要： A trailer suspension slider is provided that includes a suspension bogey. A trailer is supported on the suspension bogey and is longitudinally movable between a plurality of position relative to the suspension bogey. The trailer includes a stop bar to prevent the bogey from sliding out from underneath the trailer during braking if the pins are disengaged. A locking pin mechanism is movable between a locked position in which the locking mechanism couples the suspension bogey and the trailer in one of the plurality of positions and an unlocked position in which the trailer can move relative to the suspension bogey. The suspension bogey may collide violently with the stop bar when braking from a relatively low speed when the pins are unlocked. To this end, an energy absorption device is supported on either the trailer or the suspension bogey. The energy absorption device collapses in response to the stop bar engaging either the energy absorption device or the suspension bogey. Alternatively, an expandable cable may be used between the trailer and suspension bogey to slow the trailer as the stop bar approaches the suspension bogey.
