Problems solved by technology

[0003] At present, most of the cars installed on domestic and foreign cars are traditional independent suspension or non-independent suspension systems. Driving conditions, it is difficult to achieve the desired effect
At the same time, a small number of models are equipped with a cross-linked suspension system, but there is only one cross-linked form. Although it can improve certain performances of the car to a certain extent, it cannot intelligently change the cross-linked method according to different road conditions. Therefore, it still cannot adapt to various driving conditions.
Therefore, the current automobile suspension system cannot take into account various complex driving conditions, and cannot improve the driving safety and comfort of the automobile at the same time.

Embodiment 1

[0020] Such as Figure 5 , 6 As shown, the first cross-linking mode of the intelligent hydraulic cross-linking suspension system: A1 is connected to C1, B2, and D2, and A2 is connected to C2, B1, and D1. This is the default connection mode of the intelligent hydraulic cross-linking suspension system. In this cross-linking mode, when the vehicle moves vertically, the oil flow through the throttle valve 8 on the pipeline of the accumulator 7 is discharged from the area of ​​the piston rod, and the flow is small, so the vertical damping force generated is very small ; When the vehicle is rolling, due to the left and right cross connections, the oil flow through the throttle valve 8 on the pipeline of the accumulator 7 is discharged by the sum of the area of ​​the rodless chamber and the area of ​​the rod chamber, and the flow is very large, so it will Produces very large roll angle damping, suppressing excessive body roll motion. When the vehicle passes through a rough off-road...

Embodiment 2

[0022] Such as Figure 7 , 8 Shown: The second cross-linking method of the intelligent hydraulic cross-linking suspension system: A1 is connected to D2, A2 is connected to D1, B1 is connected to C2, and B2 is connected to C1. This cross-linking method is equivalent to the vehicle having two pairs of left and right Cross and two pairs of front and rear cross shock absorber groups, the roll and pitch motion of the body will produce a large dip angle damping, so the vehicle has high roll and pitch stability, which can prevent the vehicle from accelerating, braking or Excessive body inclination is generated when steering, which improves the posture stability and ride comfort of the body. The use of this cross-linking method when the vehicle starts and brakes can reduce the phenomenon of starting and braking nodding.

Abstract

The invention relates to an intelligent hydraulic crosslinking suspension system. The intelligent hydraulic crosslinking suspension system is characterized in that a connection opening and a lower connection opening are formed in the lower section of a shock absorber set oil cylinder, the lower connection opening is lower than the connection opening, a throttling valve a is connected with the connection opening, a connector of the left end of an external damper valve block is connected with the lower connection opening, a connector of the right end of the external damper valve block is connected with a connector of the external damper valve block at one end of a tee pipe, an energy accumulator connector below the tee pipe is connected with an energy accumulator (7) through a pipeline, a throttling valve b is arranged on the pipeline between the tee pipe and the energy accumulator, and a central control valve connector at the other end of the tee pipe is connected with a central control valve E through a pipeline. A bottom valve assembly in a shock absorber is redesigned and moved to the outside of the shock absorber, the compressing and stretching effects of an original shock absorber are kept, due to the external damper valve block, the structure is simpler, characteristics of the shock absorber are more convenient to adjust, the crosslinking function is achieved through the central control valve, then the heeling rigidity of an automobile is improved, the turning stability of the automobile is improved, the pitching rigidity is improved, and cross-country performance of the automobile is improved.

Description

technical field [0001] The invention relates to an intelligent hydraulic cross-linking suspension system, which belongs to the suspension system in the field of automobiles, and in particular to an intelligent hydraulic cross-linking suspension system which can intelligently change the cross-linking mode according to the driving conditions of the vehicle. Background technique [0002] The vehicle's demand for suspension performance will change with the change of driving conditions. For example, when the car is turning, it is hoped that the suspension will be harder to prevent the body from generating large roll motions and improve driving safety; when the car passes through uneven roads When driving, it is hoped that the suspension will be softer, so as to filter out as much as possible the uneven excitation of the ground, reduce the vibration transmitted to the body, and improve driving comfort. [0003] At present, most of the cars installed on domestic and foreign cars ar...
