Problems solved by technology

[0005] In order to avoid the damping defects caused by the linear characteristics of elastic elements, elastic elements with nonlinear characteristics such as air springs have emerged. Although it slows down part of the reaction force compared with steel springs, its shortcomings are also very obvious, such as reliability and lateral strength. Insufficient, high cost, etc., which affect its application and promotion

Embodiment Construction

[0016] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention. In the following detailed description, certain exemplary embodiments of the invention are described by way of illustration only. Needless to say, those skilled in the art would realize that the described embodiments can be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0017] Such as figure 1 As shown, the active adaptive shock absorber for automobiles includes a hydraulic cylinder 1, a piston 2 is slidably installed in the hydraulic cylinder 1, and the piston 2 separates the oil chamber of the hydraulic cylinder 1 into an upper oil chamber 3 and an upper oil chamber 3. The lower oil chamber 4 is two closed and independent oil chambers, the top of the piston 2 is connected to the pist...

Abstract

The invention discloses an automobile active self-adaption type shock absorber comprising a hydraulic oil cylinder, a piston, a piston rod and a shock absorption spring. The hydraulic oil cylinder is spaced by the piston into an upper oil cavity and a lower oil cavity. The piston is provided with an upstream one-way damping pressure valve and a downstream one-way damping pressure valve. The upper oil cavity is communicated with an upper oil cavity energy accumulator. The lower oil cavity is communicated with a lower oil cavity energy accumulator. A pressure regulating device is connected between the upper oil cavity energy accumulator and the lower oil cavity energy accumulator. When an automobile body vibrates downwards, hydraulic oil in the lower oil cavity flows back to the lower oil cavity energy accumulator through an oil tube, the shock absorption effect of an air spring is played, the upstream one-way damping pressure valve is opened, and vibration energy of the automobile body is absorbed through damping of the upstream one-way damping pressure valve, so that the bearing capacity of the air spring reaches the maximum and will not increase any more, the peak of impact of the shock absorber system on an automobile frame is reduced remarkably, and vibration of the automobile body is absorbed actively; when the automobile body vibrates upwards and tires leave the automobile frame, the process is contrary, active self-adaption shock absorption is achieved, and vibration of the automobile body is reduced effectively.

Description

technical field [0001] The invention relates to the technical field of automobile vibration damping equipment and elastic systems, in particular to an active self-adaptive composite elastic shock absorber system for automobiles. Background technique [0002] In the automobile suspension system, vibration will be generated due to the impact of the elastic element. In order to improve the ride comfort of the car, it is necessary to install a shock absorber in parallel with the elastic element in the suspension. The shock absorber in the automobile suspension system mostly uses hydraulic force shock absorber. [0003] The working principle of the hydraulic shock absorber is: when the frame (body) and the axle are in relative motion due to shock and vibration, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity passes through one cavity repeatedly. Different pores flow into another cavity. At this time, the friction between the hole wall...
