The invention discloses a disconnectable type automobile stabilizer bar. The disconnectable type automobile stabilizer bar includes a clutch assembly, a first stabilizer bar and a second stabilizer bar, wherein the clutch assembly is used for locking or disconnecting the first stabilizer bar and the second stabilizer bar; the first stabilizer bar includes a first bar body, the first bar body is movably connected with the clutch assembly, the second stabilizer bar includes a second bar body, the second bar body is movably connected with the clutch assembly, and the first stabilizer bar and the second stabilizer bar are symmetrically arranged at the two sides of the clutch assembly with the clutch assembly as the center. When a vehicle runs normally on a highway, the first stabilizer bar and the second stabilizer bar are locked into an integral structure through the clutch assembly, and when the vehicle slants toward one side, the stabilizer bars can produce a counter torque, reduce the slanting angle and increase the cornering stability. When the vehicle is under off-road conditions, the stabilizer bars are disconnected, the first stabilizer bar and the second stabilizer bar can rotate independently without mutual influence, therefore, the tire ground adhesion property of vehicle tires on a large bulge or in a pit can be improved, and the off-road performance is improved.

The invention discloses an independent suspension system, in which two suspension oil cylinders are arranged respectively between the wheel edges of the wheels on both sides and the vehicle frame; the steering mechanism drives the wheels on both sides to turn; The rod connection ends of the V"-shaped swing rod are respectively hinged with the upper part of the wheel edge of the corresponding side wheel through ball hinges, and the separated ends of the rod are hinged with the fixed member fixed under the frame along the front and rear direction through ball hinges; The rod connection ends of the lower "V"-shaped swing rods are respectively hinged with the lower part of the wheel edge of the corresponding side wheel through the ball hinge, and the two ends of the rod are separated from the fixed member fixed under the frame through the ball hinge along the front and rear direction. hinged. The invention can avoid the possible destructive influence of the suspension oil cylinder, can reliably realize the independent movement of the left and right wheels, fully utilizes the adhesion conditions of the road surface, and improves the control stability of the whole machine. On this basis, the present invention also provides a crane with the independent suspension system.

The invention relates to a control system and a control method for a vehicular active stabilizing bar. The control system comprises a lateral acceleration sensor, a piston displacement sensor, an inclinometer, a control unit and a signal output executing mechanism, wherein the signal output executing mechanism comprises a hydraulic unit and a piston. The control method comprises the following steps: confirming a series of control rules according to the following three control parameters: lateral acceleration, piston displacement and heeling angle, and then implanting the control rules into the control unit; acquiring a specific vehicle driving state by the control unit according to the combination of the three control parameters; selecting corresponding confirmed control rules according to different driving states; and confirming if changing the piston displacement and confirming the volume of the changed piston displacement. An active stabilizing bar control system adopting the control method provided by the invention has simpler structure, is suitable for all vehicles and is used for ensuring the safer and more comfortable driving of the vehicle.

The invention discloses an independent suspension system, comprising: two suspension oil cylinders, respectively arranged between the wheel edges of the wheels on both sides and the vehicle frame; a steering mechanism, used to drive the wheels on both sides to turn under the drive of the steering power cylinder; It also includes two swing rods corresponding to the wheels on both sides, one end of each swing rod is hinged with the wheel edge of the corresponding side wheel through a ball hinge, and the other end of the swing rod is hinged with the wheel edge of the corresponding side wheel through two ball hinges. The front and rear directions are respectively hinged with the fixing member fixed under the final reducer. The invention realizes the positioning of the tire mounted on the wheel edge through structural improvement, ensures that the movement of the tire meets the design requirements during the running of the crane, and can completely avoid the possible destructive influence of the suspension cylinder, thereby reliably realizing the alignment of the left and right wheels. They move independently of each other, make full use of the adhesion conditions of the road surface, and greatly improve the control stability of the whole machine. On this basis, the present invention also provides a crane with the independent suspension system.

A torsion-eliminating suspension of car is composed of a front and a back transverse stabilizing rods. With one ends directly pivoted to car body and another ends pivoted to car body via a coupling mechanism which is a rigid balance arm or a rigid balance rod with two ends respectively pivoted to a three-end commutating arm.

A number of embodiments of a piston 100 may have a shape that provides enhanced piston guidance. In such embodiments, the piston shape may include an axial profile that is configured to provide certain thrust load characteristics.

The invention relates to a vehicle hanger bracket, in particular to a hydraulic interconnection ISD (Inerter-Spring-Damper) hanger bracket. Hydraulic cylinders of a rear overhang hydraulic ISD hanger bracket are reversely connected in series, namely, the upper cavity of the left side hydraulic cylinder and the lower cavity of the right side hydraulic cylinder are connected, and the lower cavity of the left side hydraulic cylinder and the upper cavity of the right side hydraulic cylinder are connected; when the bounce directions of left and right wheels are consistent, liquid interaction is realized by a connecting pipe, and the loads borne by the two side wheels are balanced; when the bounce directions of left and right wheels are inconsistent, liquid is capable of converting the pressure difference between the upper cavity and the lower cavity into an inertia force by a hydraulic motor, the dynamic stroke of the hanger bracket is reduced, and the aim of preventing sidesway of a vehicle is reached. On the basis of an antiresonance technology of the hydraulic ISD hanger bracket, and through the combination of the interconnection sidesway prevention, the hydraulic interconnection ISD hanger bracket has the advantages that for a complicated work condition road, under the premise that the riding comfort is not influenced by negative effects, the vehicle driveability is improved, the coordination control is realized for the smoothness and the handling stability, four modalities relative to the movement of a vehicle body, of wheels are independently decoupled by an interconnection hanger bracket system, and the structure is simple and reliable, the cost is low and the implementation is easy in comparison with a driving hanger bracket.
