Problems solved by technology
[0005] The problem solved by the present invention is that in the spring damper in the existing suspension system, the damping performance of the damper is limited by its own size and the flowable space of the internal fluid, if better damping performance is to be obtained , it is necessary to increase the size of the shock absorber itself to increase the flowable space of the fluid, which will undoubtedly increase the cost and the difficulty of layout space

A car and its ECU, suspension system, spring damping device, and control system, wherein the spring damping device includes: a helical spring and a shock absorber; the spring wire of the helical spring is formed with a spring extending along the helical direction to both ends of the spring wire. Spring cavity; shock absorber, including a working cylinder with a piston cavity, a piston slidably located in the piston cavity, and a guide rod connected to the piston and having a guide rod cavity, the piston cavity is divided into a first cavity and a second cavity by the piston , the first chamber is surrounded by the piston and the guide rod, the guide rod chamber or the second chamber communicates with the first chamber; the spring inner chamber includes at least one working section along the spiral direction, and outside the working section is provided with a reducing valve connected to the spring wire The vibrator, the length direction of the guide rod is parallel to the axial direction of the coil spring, the guide rod cavity and the second cavity are respectively connected to the working section; fluid is provided in the working section so as to flow. The spring vibration damping device of the technical solution occupies a small space, reduces layout difficulty, and has good buffering and vibration damping performance.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile and its ECU, suspension system, spring damping device and control system. Background technique [0002] Suspension system is a general term for all force-transmitting connection devices between the frame of a car and the axle or wheels. Or the impact force of the car body, and attenuate the vibration caused by it, so as to ensure the smooth running of the car. The proper function of the suspension system is to support the body and improve the ride. [0003] The suspension system includes a spring shock absorber, and the spring shock absorber includes a coil spring and a shock absorber installed in the coil spring, wherein the two ends of the coil spring and the shock absorber are respectively connected to the wheel and the vehicle frame, wherein, When passing through uneven roads, the coil spring can absorb the vibration from the road, but the coil spring itse...
