Abstract

The invention discloses a liquid damping shock absorber for engineering machinery, which comprises connecting bolts, a rubber main spring, two throttling discs, a metal shell, an inertia channel, a decoupling disc, a rubber bottom film, The connecting seat on the upper part of the main spring, the rubber main spring is connected to the upper end of the metal shell, and the rubber main spring and the metal shell form a closed liquid chamber; the connecting bolt is fixedly connected to the connecting seat, the throttle plate is located in the closed liquid chamber, and The flow plate is fixedly connected to one end of the connecting bolt; the inertia channel is fixedly connected to the inner wall of the metal shell, the inertia channel is located under the throttle plate, and the decoupling plate is located in the inertia channel; the rubber bottom film is fixedly connected to the inner wall of the metal shell, And the rubber bottom membrane is located under the inertia channel. The shock absorber is used as a device for isolating vibration and reducing noise of construction machinery, especially capable of isolating mechanical vibration in a wide frequency range and alleviating low-frequency and large-amplitude shaking.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a liquid damping shock absorber for engineering machinery. Background technique [0002] Vibration isolators for construction machinery are used to isolate the vibration transmitted from the powertrain to the frame to improve the driver's ride comfort; to reduce the large vibration of the frame caused by uneven bottom surfaces and emergency braking, etc. Protect the various parts of the powertrain to prolong its service life and reduce costs; isolate or reduce cab shaking caused by uneven ground or emergency braking, and improve the driver's ride comfort. [0003] In the prior art, rubber shock absorbers are usually used for vibration isolation of construction machinery, and the hysteresis characteristic of rubber is used to realize vibration isolation. But very poor for large-scale shaking effect, can affect the working performance and the life-span of each parts and complete machine of engi...
