Description
Technical Field
The utility model belongs to the technical field of automobile shock absorbers, and particularly relates to a series compensation type semi-air suspension shock absorber.
Background
The term "shock absorber" is a generic term in the automotive chassis industry, which is effectively a vibration damper. Shock absorbers are used in automobiles not only on suspensions, but also in other locations. For example, it is used in cabs, saddles, steering wheels, etc., and it can also be used as a bumper in a vehicle bumper. In the suspension system, the elastic element is impacted to generate vibration, so as to improve the running smoothness of the automobile, the shock absorber is arranged in parallel with the elastic element in the suspension, and the shock absorber is mostly a hydraulic shock absorber in the automobile suspension system, so that the working principle is that when the frame (or the automobile body) and the axle are subjected to vibration to generate relative motion, the piston in the shock absorber moves up and down, and oil in the cavity of the shock absorber repeatedly flows into the other cavity from one cavity through different holes. At this time, the friction between the hole wall and the oil and the internal friction between the oil molecules form damping force on vibration, so that the automobile vibration energy is converted into oil heat energy, and then absorbed and emitted into the atmosphere by the shock absorber. When the oil liquid channel section and other factors are unchanged, the damping force increases and decreases along with the relative movement speed between the vehicle frame and the vehicle axle (or the vehicle wheels), and is related to the viscosity of the oil liquid. The shock absorber and the elastic element bear the tasks of buffering impact and vibration, and the excessive damping force can deteriorate the elasticity of the suspension, and even damage the shock absorber connecting piece.
The steering damper is a damping type damper installed in a steering system of an automobile, and has various structures, and is generally a cylinder type damper filled with viscous liquid inside, and has a structure similar to that of a suspension damper. The function of the brake is to prevent the steering wheel of the automobile from generating self-excitation shimmy or forced shimmy and also to prevent the brake from deviating. The steering damper is a damping damper installed in a steering system of an automobile, and is used for reducing the impact directly from an uneven road surface and the vibration of the steering system, and improving the steering performance. If power steering is used in the steering mechanism, the impact can be reduced and the vibration can be alleviated by using the power steering, so that the steering damper is not particularly used in practice.
Since the birth of the mid-nineteenth century, air suspensions have undergone the development of a century, and have undergone various changes such as "pneumatic spring-air bag composite suspension→semi-active air suspension→central inflation/deflation suspension (i.e., ECAS electric control air suspension system)". It was applied to trucks, buses, cars and railroad cars by the fifties of the twentieth century. At present, the foreign high-grade buses almost all use air suspensions, the proportion of the heavy-duty trucks using the air suspensions is over 80 percent, and the application amount of the air suspensions on light automobiles is rapidly rising. Some cars are also increasingly mounted using air suspensions such as lincoln, benz300SE and Benz600 in germany, and the like. The use of air suspensions is almost the only choice for some special vehicles (such as instrument cars, ambulances, special military vehicles, and required container vehicles with high requirements for shock protection). While China is still in a starting stage, the air suspension system is only applied to some luxury buses and small heavy trucks and trailers.
Generally, the softer the elastic damping element, the less energy is stored, the better the damping effect and the better the jolt damping effect. However, the elastic damping element is too soft in design and cannot provide good supporting force, and if the elastic damping element is too hard in design, energy storage through obstacles becomes large, and vibration is also large. The rigidity of the elastic damping element cannot be regulated in the current commercial automobile shock absorbers generally, and the current commercial automobile shock absorbers cannot meet the requirements of various road conditions or loads on the shock absorption effect.
In addition, when the automobile turns rapidly, the automobile body can incline outwards under the action of centrifugal force, the shock absorber is compressed, the existing automobile mainly depends on the torsion force of the torsion spring of the anti-rolling rod on the auxiliary frame to reversely press downwards to support forwards, the rolling degree of the automobile is corrected, and the phenomenon of braking nodding still can be generated when the automobile brakes at a high speed, so that the comfort experience is affected.
