Referring to fig. 1 to 4, a first embodiment of the present utility model provides a torsion bar spring space diagonal type variable stiffness decoupling suspension, which comprises a column 1, a control arm structure 2, a push rod 3, a torsion bar spring 4, an electromagnetic clutch 5 and a coil spring 6.

Referring to fig. 1 to 3, in the present embodiment, a control arm structure 2 is disposed on a column 1. Wherein the control arm structure 2 comprises an upper control arm 21 and a lower control arm 22. One end of the upright 1 is connected to an upper control arm 21 and the other end is connected to a lower control arm 22. One end of the push rod 3 is connected with the lower control arm 21 through a hinge sleeve and a ball pin, and one end of the push rod, which is far away from the lower control arm 21, is connected with the torsion bar spring 4 through the upper end support swing arm 7, and is used for driving the push rod 3 to move when the lower control arm 22 swings, so that the upper end support swing arm 7 is driven to rotate to enable the torsion bar spring 4 to be twisted. Specifically, one end of the upper end bracket swing arm 7 is connected with the push rod 3 through a hinge sleeve and a ball pin, and one end of the upper end bracket swing arm, which is far away from the push rod 3, is connected with one end of the torsion bar spring 4. One end of the torsion bar spring 4, which is far away from the upper end bracket swing arm 7, is also connected with the electromagnetic clutch 5. The utility model can realize the change of the rigidity of the suspension by changing the working state of the torsion bar spring 4.

Referring to fig. 1 to 4, in the present embodiment, the electromagnetic clutch 5 includes a driving portion and a driven portion. Wherein, driven part and the chassis fixed connection of vehicle. The active part is connected with the spiral spring 6 through a rotating bracket. Preferably, the rotating support is a rocker 8. The torsion bar spring space oblique type multi-decoupling suspension is configured such that when the electromagnetic clutch 5 is powered on, the rocker 8 can be locked to stop the spiral spring 6, meanwhile, the push rod 3 can move under the driving of the control arm structure 2 to further drive the torsion bar spring 4 to twist so that the torsion bar spring space oblique type multi-decoupling suspension works in a high-rigidity mode, and when the electromagnetic clutch 5 is powered off, the push rod 3 can move under the driving of the control arm structure 2 to further drive the torsion bar spring 4 to twist so as to drive the spiral spring 6 to move so that the torsion bar spring space oblique type multi-decoupling suspension works in a low-rigidity mode.

Referring to fig. 1, a torsion bar spring 4 and a coil spring 6 of the present utility model are connected in series by a rotary electromagnetic clutch fixed to a vehicle body. When the electromagnetic clutch 5 is powered off and closed, the control arm structure 2 drives the push rod 3 to move, so that the torsion bar spring 4 is pushed to drive the spiral spring 6 connected in series at the lower end part of the torsion bar spring to compress. Since the torsion bar spring 4 has a stiffness much greater than that of the coil spring, the torsion bar spring 4 at this time corresponds to a rigid body, so that the suspension can be operated in the coil spring 6 mode (low stiffness mode). When the electromagnetic clutch 5 is electrified to work, the rotating bracket on the lower end part of the torsion bar spring 4 is locked, and at the moment, the push rod 3 can only push the torsion bar spring 4 to rotate to do work, and the spiral spring 6 does not work (high-rigidity mode).

Referring to fig. 1, in this embodiment, the torsion bar spring spatially skewed multi-decoupling suspension further comprises a tie rod 10. The tie rod 10 is disposed on the column 1 for controlling the steering of the vehicle.

Referring to fig. 1, a second embodiment of the present utility model provides a vehicle including a plurality of torsion bar spring spatially canted variable stiffness decoupling suspensions as described above. When the automobile runs on a bumpy road surface at a low speed or on a road condition, the controller controls the electromagnetic clutch 5 to be powered off and closed, at the moment, the driving part and the driven part are separated, the push rod 3 drives the torsion bar spring 4 and the spiral spring 6 connected with the driving part of the clutch to work, the suspension stiffness is provided by the spiral spring 6 with small stiffness and large travel, and the suspension stiffness is softer, so that the vibration absorption on the bumpy road surface is better, and the automobile has higher driving smoothness. When the automobile runs at a high speed or is in an overbending working condition, the controller controls the electromagnetic clutch 5 to work in a power-on mode, the driving part and the driven part are fixed in a suction mode, the rocking block 8 is locked, the spiral spring 6 stops working, only the torsion bar spring 4 works, and at the moment, the suspension stiffness is provided by the torsion bar spring 4 with high stiffness. Since the torsion bar spring 4 has a stiffness greater than that of the coil spring 6, the vehicle is allowed to have better running stability. The torsion bar spring space oblique variable stiffness decoupling suspension utilizes the working condition characteristics of high stiffness of the torsion bar spring 4, small stiffness of the spiral spring 6 and large travel, so that intelligent switching between a high stiffness mode and a low stiffness mode can be performed according to the running working condition of the whole vehicle, the stiffness of a vehicle chassis can be adjusted, and the vehicle steering stability is good, so that the torsion bar spring space oblique variable stiffness decoupling suspension has better riding comfort.
