Problems solved by technology

[0003] However, the above-mentioned hydraulic mount shock absorber will cause cavitation effect during the rapid stretching process in the high-frequency band, and the cavitation effect will not only corrode the inner surface of the parts, thereby reducing the service life of the equipment, but also the cavitation effect. A large number of bubbles will cause the high-frequency vibration to compress and stretch only the bubbles due to the characteristics of easy compression and stretching of the gas, so that the liquid will form a broken flow phenomenon, which is also one of the important factors leading to high-frequency hardening

Embodiment Construction

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038]The "directional swirl flow" in the present invention refers to a single direction of circulation along the hydraulic chamber, that is, a directional swirling flow. "Adaptation" in the present invention refers to the accelerated directional swirl of the conversion mechanism that is proportional to the increase of the amplitude and vibration frequency, so the frictional heat energy converted by the swirl is also greater, that is to say, with the increase of the amplitude and vibration frequency The higher the vibration frequency, the higher the heat generated and the more obvious the shock absorption effect, which can prevent the hardening phenomenon, so the system is defined as an "adaptive" damping system.

[0039] As shown in the figure, the present invention provides a directional swirl self-adaptive fluid resistance suspension shock abs...

Abstract

The invention discloses a directional swirl self-adaptive liquid resistance suspension shock absorber, which comprises a base (1), a bottom film (2), a partition plate (3), an elastic body ( 4) and the connection seat (5), the base film (2) and the elastic body (4) form a hydraulic chamber, which is filled with damping fluid, and the partition plate (3) divides the hydraulic chamber into an upper chamber (6.1 ) and the lower chamber (6.2), and the partition plate (3) is provided with an inertia channel (3.1) connecting the upper chamber (6.1) and the lower chamber (6.2), characterized in that: the upper chamber (6.1) There is a conversion mechanism that converts the reciprocating vibration energy of the damping fluid in the vertical direction into kinetic energy that revolves in a single direction. The invention provides a cavitation phenomenon that can be avoided in the high-frequency band, improves the service life of equipment, and can eliminate the high-frequency hardening phenomenon, so that the directional swirl self-adaptive liquid resistance suspension shock absorber with good vibration reduction effect is achieved.

Description

technical field [0001] The invention relates to the technical field of shock absorbers, in particular to a directional swirl adaptive liquid resistance suspension shock absorber. Background technique [0002] Mounted shock absorber is a connecting piece that installs the powertrain on the frame to reduce the vibration and noise generated by the powertrain. It first appeared in the automotive industry and was used for engine installation. The hydraulic mount shock absorber is a mount shock absorber developed on the basis of the rubber mount combined with the hydraulic damping mechanism. Its basic structure is a metal skeleton, a rubber main spring and a base that are connected in sequence. The three are enclosed to form an inner cavity. The inner cavity is provided with an inertial channel body that divides the inner cavity into an upper chamber and a lower chamber. There are inertial channels and decoupling membranes. In the static state, the rubber main spring is used to ...
