Problems solved by technology

However, even for models on the same platform, due to changes in the mass of the vehicle and the position of the center of mass of the vehicle, the requirements for the roll stiffness of the rear suspension are also different. In order to meet the roll stiffness of the suspension, the suspension has to be redesigned, resulting in poor versatility

Abstract

The invention discloses a back torsion beam suspension frame structure, which comprises a left longitudinal beam (4), a right longitudinal beam (4), a transverse beam (12), a lining casing (3), a vibration damper installation bracket (6) and a spring installation bracket (7), and is characterized in that: a transverse stabilizer rod (11) is arranged on a hollow part of the transverse beam (12), and is fixed on the left and right longitudinal beams (4) through left and right side brackets. A replaceable stabilizer rod is arranged on a back torsion beam suspension frame, so that the structures of components such as the transverse beam and the like are optimized, the total weight of the suspension frame is reduced, and the economic efficiency of an entire vehicle is realized. The back suspension frame is general, so that spare part cost of the same platform car type on the market is lowered, and better economic benefit is achieved. The entire stabilizer rod is hidden inside the transverse beam, so that the arrangement space of the back suspension frame is not influenced on the whole, the structure is simple and practical, and convenience is brought to implementation.

Description

technical field [0001] The invention belongs to the automobile suspension system, and more specifically, the invention relates to a rear torsion beam suspension structure. Background technique [0002] Suspension is an important part of the vehicle, it is the connecting force transmission device between the body and the wheels, and it is also an important component of the driving safety and comfort of the vehicle. There are many types of suspensions. The commonly used suspension structures include torsion beam suspension, trailing arm suspension, McPherson suspension, double wishbone suspension and multi-link suspension. The torsion beam suspension is adopted by many models because of its simple structure, relatively low manufacturing cost, and good cost performance. Suspension must meet the requirements of dynamics on the basis of strength. The roll stiffness of the rear suspension has a great influence on the handling stability. Many models with rear torsion beam suspens...
