Description
Technical Field

Background
The suspension assembly is a vehicle safety guarantee. The suspension assembly includes a suspension arm connected to the wheel and the vehicle body, and a suspension decoupling arrangement disposed on an axis extending between the suspension arm and the vehicle body. Suspension stiffness is a measure of the ability of a suspension to resist deformation and is equal to the ratio of the load to which the suspension is subjected to and the deformation of the suspension caused by that load. Suspension stiffness is the most considered factor in suspension design. Specifically, the suspension is classified into linear stiffness (pitch stiffness) and angular stiffness (roll stiffness). The vehicle can generate parallel wheel jump and roll due to specific road conditions in the running process, and the pitch stiffness and the roll stiffness which are respectively required to be provided by the suspension are respectively balanced and offset. Conventional suspensions use two base springs plus an anti-roll bar to provide suspension stiffness, with the base springs' pitch stiffness and roll stiffness being coupled, with one stiffness being changed and the other being changed. In such a case, when one of the stiffnesses is already sufficient for the design and the other is not (typically the roll stiffness is not sufficient), it is necessary to add a stabilizer bar (anti roll bar). The addition of the anti-roll bar can increase the angular stiffness without affecting the linear stiffness, and in another case, if it is desired to increase the linear stiffness without affecting the angular stiffness, a third spring suspension structure needs to be added.
However, the higher the actual requirement for angular stiffness in the prior art, the more complex and difficult the design and calculation of conventional suspension configurations becomes.
