摘要： A suspension assembly for a vehicle may include a first stabilizer bar operably coupled to a first wheel on a first side of the vehicle, a second stabilizer bar operably coupled to a second wheel on a second side of the vehicle, and an chassis coupler comprising an inverter housing and an actuator assembly. The actuator assembly may be operable to arrange the first stabilizer bar and the second stabilizer bar in a selected one of a connected state, a disconnected state, and an inverted state. The inverter housing may be alternately constrained to one of the first stabilizer bar or the chassis coupler based on a position of the actuator assembly to define each of the connected state, the disconnected state and the inverted state.

摘要： A cantilever bushing assembly anchors the central torsional section of a vehicular stabilizer bar in a cantilevered manner relative to a vehicle understructure. The bushing assembly comprises a bracket having a pocket centered on a pocket axis that coincides with a longitudinal axis of the stabilizer bar. Two plastic outer cans are cooperatively slidable into the pocket. Each outer can has an anti-rotation lobe received in respective keyways formed in the pocket. A rubber buffer is bonded to each outer can. Each rubber buffer has a frusto-cylindrical inner bearing surface that forms an arcuate portion of an interior bushing diameter. The inner bearing surface is post-vulcanization bonded to the central torsional section of the stabilizer bar. An arched rate plate is embedded within each rubber buffer. The rubber buffers compress in the area of the inner bearing surfaces and constrict about the central torsional section of the stabilizer bar.

摘要： The ECU of the stabilizer control apparatus determines, based on a high frequency component of a wheel acceleration and a low frequency component of a wheel speed difference, whether a road surface state is a rough road state or a smooth road state. When the road surface state is determined to be the rough road state, the ECU sets a turning determination threshold to a rough road threshold. When the road surface state is determined to be the smooth road state, the ECU sets the threshold to a smooth road threshold. When a turning determination parameter is greater than the threshold, the ECU sets each of first, second, and third cylinders to a lock state to increase rigidity of stabilizers. When the turning determination parameter is smaller than the turning determination threshold, the ECU sets each of the cylinders to a free state to decrease the rigidity of the stabilizers.

摘要： A bogie positioning system and method for a work machine. The bogie positioning system adapted to selectively engage a wheel of a work machine to a ground surface through a bogie assembly wherein the bogie assembly may have a front wheel coupled to a rear wheel through a bogie coupling mechanism. The bogie coupling mechanism comprising a beam with a rotary joint. The rotary joint allowing the front wheel to rotate about a rotary axis relative to the rear wheel. The beam is coupled to a chassis of the work machine with at least one actuator coupled to the beam. A control unit is in communication with the bogie assembly, a user input interface, and a plurality of sensors, generating command signals to actuate the actuator based on the input signals, thereby selectively engaging the front wheel or the rear wheel with the ground surface.

摘要： An active suspension control unit may include an actuator having an active roll stabilization (ARS) structure to variably adjust response characteristics of a suspension, and a controller for determining a driving situation of a vehicle through information input from a sensor, and determining a final desired control value of the actuator based on a desired relative suspension vertical force value set in advance according to the driving situation and a difference value generated by a difference between left and right wheel's relative suspension vertical velocities.

摘要： An air management system for a vehicle having a first pneumatic circuit and a second pneumatic circuit, in which the first and second pneumatic circuits are pneumatically connected in a neutral position via a cross-flow mechanism. The first pneumatic circuit includes a first leveling valve configured to adjust independently the height of a first side of the vehicle. The second pneumatic circuit includes a second leveling valve configured to adjust independently the height of a second side of the vehicle. The first and second leveling valves are configured to establish pneumatic communication between the first and second pneumatic circuits when the first leveling valve is not independently adjusting the height of the first side of the vehicle and the second leveling valve is not independently adjusting the height of the second side of the vehicle.
