Five-link suspension system and vehicle

Abstract

A five-link suspension system comprises a steering knuckle, a toe-in arm, a transverse swing arm, a guide arm, a longitudinal swing arm and a control arm. The coordinates of a first connecting shaft of the toe-in arm are 3155-3165 mm, -279--289 mm and 15-25 mm, and the coordinates of a second connecting shaft of the toe-in arm are 3050-3060 mm, -732--742 mm and 14-24 mm; the coordinates of a thirdconnecting shaft of the transverse swing arm are 2981-2991 mm, -382--392 mm and 154-164 mm, and the coordinates of a fourth connecting shaft of the transverse swing arm are 2916-2926 mm, -729--739 mmand 169-179 mm; the coordinates of a fifth connecting shaft of the guide arm are 2810-2820 mm, -650--660 mm and 96-106 mm, and the coordinates of a sixth connecting shaft of the guide arm are 2672-2682 mm, -422--432 mm and 114-124 mm; the coordinates of a seventh connecting shaft of the longitudinal swing arm are 2677-2687 mm, -408--418 mm and -37--47 mm, and the coordinates of an eighth connecting shaft of the longitudinal swing arm are 2849-2859 mm, -693--703 mm and -120--130 mm; and the coordinates of a ninth connecting shaft of the control arm are 2958-2968 mm, -713--723 mm and -69--79 mm, and the coordinates of a tenth connecting shaft of the control arm are 3099-3109 mm, -265--275 mm and -70--80 mm. The toe-in curve of the five-link suspension system has very high linearity. The invention also relates to a vehicle.

Description

technical field [0001] The invention relates to the technical field of automobile suspension, in particular to a five-link suspension system and a vehicle. Background technique [0002] At present, more and more models adopt multi-link structure on the rear suspension, from mid-level cars Focus, Mazda 3, Sagitar, Octavia to slightly higher-level Magotan, Accord, Mazda 6, Toyota Reiz, Mondeo, and even Mercedes-Benz, BMW For the whole series, etc., the rear wheel suspension structure is all multi-link type. Volkswagen's PQ35 and PQ46 platforms have abandoned the four-link suspension structure with rear wheel trailing arm and torsion beam on the previous PQ34 and PQ45 platforms, and instead adopted a five-link suspension structure with better performance. [0003] In the existing five-link technical scheme, the toe-in curve of the suspension is relatively poor, which is not conducive to the stability of the vehicle. Contents of the invention [0004] In view of this, the pr...
