[0002] The torsion beam type suspension is a type of automobile rear suspension. It balances the up and down movement of the left and right wheels through a torsion beam to reduce the sway of the vehicle and maintain the stability of the vehicle. It belongs to a type of non-independent suspension; it is also called semi-independent suspension. Currently, the main beam structure of the torsion beam of the common non-independent rear suspension system of passenger cars is a hot-formed steel plate, an open beam.

[0003] There are certain problems in the use of the existing torsion beam. When the vehicle wheels are bumpy during driving, they are supported and cooperated through the torsion beam. When the road is rough, the overall pressure of the vehicle on the torsion beam is relatively large, which increases the burden on the torsion beam and reduces the service life of the torsion beam. And the existing torsion beam has limited bearing capacity during use. In view of the above problems, a hydroformed multi-functional rear torsion beam is proposed for improvement and upgrade. Content of the Utility Model

Specific embodiments

[0023] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As Figure 1 - Figure 5 shown, the design of a hydraulic forming multi-functional rear torsion beam provided in this embodiment includes a torsion beam body 1, and the torsion beam body 1 includes an elastic element 2, a shock absorber 3 and a torsion cross beam 5. Longitudinal arms 4 are provided at both ends of the torsion cross beam 5, and elastic elements 2 are fixedly provided inside the longitudinal arms 4. A shock absorber 3 is provided behind the elastic element 2. A disassembly component 7 is provided inside the torsion cross beam 5, and fixing components 6 are provided at both ends of the torsion cross beam 5.

[0025] Preferably, the fixing component 6 includes a threaded knob 62, a rotating rod 65 and a clamping block 66. A clamping groove 61 is opened inside the longitudinal arm 4. Clamping blocks 66 are provided at both ends of the torsion cross beam 5, and the clamping blocks 66 are slidably connected inside the clamping groove 61. Notches 60 are provided at the upper ends of the two longitudinal arms 4. Two threaded knobs 62 are symmetrically provided at the upper end of the torsion cross beam 5, and the threaded knobs 62 are fixedly connected with screw rods 63. The outer walls of the two screw rods 63 are threadedly connected inside the connecting shaft piece 64 and the extending ends are connected to the notch 60. Two rotating rods 65 are provided inside the torsion cross beam 5 on one side of the screw rod 63.

[0026] By inserting the torsion beam 5 into the internal clamping grooves 61 of the two longitudinal arms 4 through the clamping blocks 66 on both sides, and then the operator rotates the threaded knob 62 to drive the screw rod 63 to rotate inside the connecting shaft piece 64, so that the screw rod 63 fixes the torsion beam 5 on the longitudinal arm 4. At the same time, rotating the rotating rod 65 stably fixes the torsion beam 5, which is beneficial to improving the installation tightness of the torsion beam 5.

[0027] Preferably, the disassembly component 7 includes a cover plate 73, a reinforcing rib 78 and a threaded rod 77. A placement groove 71 is formed inside the torsion beam 5, and a sliding groove 72 is formed on the inner wall of the placement groove 71. The reinforcing rib 78 is fixedly installed inside the limiting box, and sliders 79 are arranged on both sides of the limiting box. The sliders 79 are slidably connected inside the sliding groove 72. A plug rod is arranged at the rear side of the cover plate 73 and the plug rod is clamped on the inner wall of the torsion beam 5. Two grips 74 are symmetrically arranged on the front outer wall of the cover plate 73. Hinge blocks 75 are fixedly arranged at both ends of the cover plate 73. The threaded rod 77 is threadedly arranged inside the hinge block 75, and an anti-slip knob 76 is fixedly installed at one end of the threaded rod 77.

[0028] By rotating the anti-slip knobs 76 on both sides of the cover plate 73, the threaded rod 77 is driven to rotate out of the hinge block 75. Then, pulling the grip 74 removes the cover plate 73 from the torsion beam 5. Then, the reinforcing rib 78 inside the limiting box is moved into the placement groove 71 inside the torsion beam 5 by using the slider 79, and finally the cover plate 73 is covered.

[0029] The working principle and process of the present utility model: When the vehicle is on a slope and bumps, the torsion beam 5 and the longitudinal arm 4 cooperate with each other to rotate, and then the shock absorber 3 and the elastic element 2 cooperate to buffer and protect the vehicle during driving. By inserting the torsion beam 5 into the internal clamping grooves 61 of the two longitudinal arms 4 through the clamping blocks 66 on both sides, and then the operator rotates the threaded knob 62 to drive the screw rod 63 to rotate inside the connecting shaft piece 64, so that the screw rod 63 fixes the torsion beam 5 on the longitudinal arm 4. At the same time, rotating the rotating rod 65 stably fixes the torsion beam 5, which is beneficial to improving the installation tightness of the torsion beam 5. The torsion beam 5 often bears a relatively large load during driving bumps. By rotating the anti-slip knobs 76 on both sides of the cover plate 73, the threaded rod 77 is driven to rotate out of the hinge block 75. Then, pulling the grip 74 removes the cover plate 73 from the torsion beam 5. Then, the reinforcing rib 78 inside the limiting box is moved into the placement groove 71 inside the torsion beam 5 by using the slider 79, and finally the cover plate 73 is covered, which is beneficial to improving the hardness of the torsion beam 5 itself and facilitating disassembly and maintenance.
