Abstract
The invention discloses a novel torsion beam assembly, comprising a cross beam, a longitudinal arm, a spring base and a first reinforced plate. The longitudinal arm has a main body; the upper end of the main body is inwards projected with a connecting part; the lower end of the main body is outwards projected to form a mounting part; the longitudinal arm is fixedly mounted at the two ends of the cross beam through the connecting part. The first reinforced plate is respectively connected with the cross beam and the longitudinal arm; and the inner wall of the first reinforced plate is bonded with the cross beam and the longitudinal arm. The spring base is fixedly mounted on the first reinforced plate, and is positioned at the inner side of the mounting part. A connecting block is arranged below a connected place of the cross beam and the longitudinal arm, and is connected to the cross beam and the longitudinal arm. The first reinforced plate is respectively connected with the cross beam and the longitudinal arm, and the connecting block is arranged below the connected place of the cross beam and the longitudinal arm, so that the strength of the connected place of the cross beam and the longitudinal arm is improved. The spring base is fixedly mounted on the first reinforced plate to prevent force from being directly transferred to the cross beam from the spring base, so that the torsion force of the cross beam is reduced, the torsion deformation of the cross beam is reduced, and the service life is prolonged.
