Problems solved by technology

Once the assembly space is fixed, the rubber stiffness can only be adjusted by adjusting the rubber hardness or the amount of compression deformation, which can only adapt to the vibration and shock amplitude absorption of a certain band, and has certain restrictions on the adjustment of the ride comfort of the vehicle, and the stiffness cannot be better. The improvement and random adjustment will affect the smoothness and ride comfort of the whole vehicle

Abstract

The invention discloses a bushing assembly, a control device and control strategy of the bushing assembly and a vehicle. The bushing assembly comprises an inner cylinder, an outer cylinder and a main spring. The outer cylinder is arranged on the outer side of the inner cylinder in a sleeving manner and is spaced from the inner cylinder. The main spring is arranged between the inner cylinder and the outer cylinder, multiple hydraulic cavities which are arranged at intervals in the circumferential direction are formed in the main spring, and the pressure in the multiple hydraulic cavities is adjustable so that the inner cylinder or the outer cylinder can get away from or close to the center of the bushing assembly. According to the bushing assembly, the rigidity of the bushing assembly can be changed according to needs, and then the inner cylinder or the outer cylinder can move away from or towards the center of the bushing assembly.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a bush assembly, a control device, a control strategy and a vehicle. Background technique [0002] During the operation of the car, the driver keeps operating the vehicle, turning, overtaking, and changing lanes. The vehicle undergoes complex transformation and swing under different working conditions, and the instantaneous stability of the flexible components in the suspension is adjusted to meet the driving requirements of the vehicle. To improve the ride comfort and handling stability of the car. [0003] In the traditional structural form, by using the change of propulsion force to compress the deformation of the rubber, the effective stiffness change is produced to attenuate the instantaneous impact generated during propulsion and retreat. Once the assembly space is fixed, the rubber stiffness can only be adjusted by adjusting the rubber hardness or the amount of compression deforma...
