[0003] However, since the gas volume in the air spring is constant, the stiffness of the air spring cannot be adjusted to a large extent. When tuning the whole vehicle, you can only choose the comfortable or sporty mode, that is, the stiffness is soft or hard, giving the ride Poor driving experience for car occupants and drivers

Embodiment Construction
[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0020] This embodiment provides a pillar-type double-chamber diaphragm air spring, which is used in passenger vehicles to meet the dual needs of users for vehicle control and comfort; at the same time, the dual-chamber The air spring can be integrated on an ordinary shock absorber, or on a damping variable shock absorber to form a strut-type double-chamber air spring assembly.
[0021] see Figure 1-Figure 3 , in this solution, the air spring provided includes an upper support 10, a capsule body 20 and a damping cylinder, wherein the upper support 10, the capsule body 20 and the damping cylinder jointly form a first air chamber A; The cylinder block 31 of the cylinder is also sleeved with a piston 40, and a second ...

The invention discloses a supporting column type double-cavity membrane type air spring, and relates to the technical field of passenger car air spring design, the supporting column type double-cavity membrane type air spring comprises an upper support, a bag skin body and a damping cylinder, and the upper support, the bag skin body and the damping cylinder jointly form a first air cavity; the cylinder body of the damping cylinder is further sleeved with a piston, a second air cavity is formed in the piston, an electromagnetic switch valve is arranged on the piston, and the first air cavity and the second air cavity are communicated or disconnected through opening and closing of the electromagnetic switch valve; the first air cavity and the second air cavity are communicated or disconnected through on-off of the electromagnetic switch valve, change of the working volume of the air spring is achieved, the rigidity adjusting function of the two air cavities on the air spring is brought into full play on the premise that the use space and bearing requirements are met, and when the road condition changes sharply, the service life of the air spring is prolonged. The air pressure in the bag skin body changes accordingly, finally the rigidity of the two air springs is embodied, and the double requirements of a user for vehicle control and comfort are met.
Description
technical field [0001] The invention relates to the technical field of passenger car air spring design, in particular to a pillar-type double-chamber membrane-type air spring. Background technique [0002] The air spring is filled with compressed air in a sealed container. Because the gas has certain compressibility, the air spring has ideal nonlinear elastic characteristics, and on the premise of adding a height sensor, the air spring can Inflate and deflate to adjust the height of the vehicle. [0003] However, since the gas volume in the air spring is constant, the stiffness of the air spring cannot be adjusted to a large extent. When tuning the whole vehicle, you can only choose the comfort mode or the sports mode, that is, the stiffness is soft or hard. Bad driving experience for car occupants and drivers. [0004] Therefore, designing an air spring with adjustable stiffness to meet the requirements of vehicle comfort and stability is currently a topic that designers ...
