The torsion beam semi independent suspension is a type of rear suspension device for automobiles, which adds a balance bar to the torsion beam non independent suspension to tilt the wheels and maintain the stability of the vehicle. This suspension system consists of four parts: a torsion crossbeam that bears the main vertical and lateral moments, longitudinal swing arms welded to the left and right sides of the torsion crossbeam, elastic elements and connecting brackets arranged at the front end of the longitudinal swing arms για τη σύνδεση του σώματος του οχήματος και ένα σύστημα αποσβεστήρα ελατηρίου. The advantages of the torsion beam semi independent rear suspension system include simple structure, light weight, no need for rear wheel alignment during vehicle assembly, reduced assembly time, and small space occupation, making it easy to obtain a larger rear space. In addition, the spring damper system is easy to match and arrange, which is beneficial for controlling the motion ratio of the wheels relative to the spring damper. Τα χαρακτηριστικά στρεπτικής διασταύρωσης μπορούν να αντικαταστήσουν τη λειτουργία της γραμμής σταθεροποιητή. However, this suspension system also has some unfavorable factors, such as the generation of torsional and shear stresses on the torsion beam, high stress at the welded connection, and the limitation of the load that the rear axle can bear by the strength of the torsion δέσμη. In addition, to ensure driving stability, the connection points of the longitudinal swing arm elastic bushings on both sides are subjected to complex forces, and the wheels on both sides affect each other, resulting in poor comfort. ‌

Another characteristic of the torsion beam semi independent suspension is the use of a thick torsion beam to weld the longitudinal rocker arms on the left and right sides together. The advantage of this suspension is that it has a simple structure, occupies very little space at the left and right wheels, and the body's camber angle remains unchanged. Οι απορροφητές σοκ δεν βιώνουν άγχος κάμψης, με αποτέλεσμα χαμηλή τριβή και καλή άνεση. If properly tuned, the best results can be achieved with minimal cost and space, so small and compact cars often use this form of rear suspension. ‌

Overall, torsion beam semi independent suspension is an economical and practical rear suspension solution widely used in small and medium-sized family sedans with front wheel drive. Παρά τα μειονεκτήματα, όπως η κακή άνεση και τα πιθανά προβλήματα άγχους, τα πλεονεκτήματά της, όπως η απλή δομή, το χαμηλό κόστος και η υψηλή απόδοση του χώρου, καθιστούν την επιλογή πίσω ανάρτησης για πολλά μοντέλα αυτοκινήτων
