AI Technical Summary

Technical Problem

The existing torsion beam suspension cannot adjust the position and opening direction of the beam during the adjustment process, resulting in high cost and cycle of smooth performance evaluation and adjustment.

Method used

An adjustable torsion beam structure is designed. By setting a longitudinal arm positioning frame and a beam positioning frame on the longitudinal arm and the beam, and adding a transition bracket between the two, the transition bracket allows the transition bracket to be translated and adjusted on the longitudinal arm positioning frame and rotated on the transverse beam positioning frame, thereby changing the stiffness characteristics and inclination center of the torsion beam.

Benefits of technology

The forward and backward movement and rotation of the torsion beams are achieved, the adjustment margin is increased, the cost and cycle of component development and sample production is reduced, and the vehicle is improved.

Abstract

The utility model discloses an adjustable torsion beam structure and an automobile suspension, and relates to the field of automobile torsion beams, and the adjustable torsion beam structure comprises a trailing arm positioning frame arranged on a torsion beam trailing arm; the cross beam positioning frame is arranged on the torsion beam cross beam; one end of the transition support is detachably connected with the longitudinal arm positioning frame, the connecting position of one end of the transition support is distributed in the length direction of the torsion beam longitudinal arm, the other end of the transition support is detachably connected with the cross beam positioning frame, and the connecting position of the other end of the transition support is distributed in the circumferential direction of the torsion beam cross beam; the torsion beam structure is designed on the basis of a traditional structure, the transition support is additionally arranged, the connecting position of the transition support on the longitudinal arm positioning frame can be adjusted in a translation mode, the connecting angle of the transition support on the cross beam positioning frame can be adjusted in the circumferential direction, and torsion beams of different structure schemes can be evaluated and adjusted only by adjusting some bolts. And the part development cost and the sample piece manufacturing cost are greatly reduced, and the period is shortened.
