The invention discloses an all-metal dry friction three-way anti-strong shock vibration isolation buffer. The outer casing and inner support cylinder of the vibration isolation buffer are used as fixed parts, and the upper sleeve is used as a movable part. There is a disc-shaped wire mesh damping member between the cylinders, which provides vertical and horizontal vibration isolation when the vibration isolation buffer is excited by external vibrations; there are wire mesh buffers on the outside of the inner support cylinder and the outside of the convex ring of the bottom plate When the components are strongly impacted by the outside world, the upper sleeve is in contact with the wire mesh buffer member to play a vertical and horizontal buffering role; the coil spring between the adjusting bolt and the bottom plate provides support for the vibration isolation equipment and buffering and reset. effect. The vibration isolation buffer can realize three-way vibration isolation and withstand strong impact vibration, and is suitable for the field of vibration isolation and buffering of off-road vehicles or extreme working conditions.
Description
technical field [0001] The invention relates to the field of mechanical vibration isolation and buffering, in particular to a three-way anti-strong impact vibration isolation buffer for on-board instruments and equipment of armored vehicles. Background technique [0002] With the continuous advancement of science and technology, the maneuverability of armored vehicles has been greatly improved. During the driving of armored vehicles, the vibration of various parts of the vehicle body caused by the engine and transmission system is relatively large, and its vibration frequency is mainly concentrated in the middle and high frequency bands; at the same time, the unevenness of the road transmits vibration excitation to the vehicle body through the action system, and The vibration frequency is mainly concentrated in the middle and low frequency bands. However, in addition to normal off-road driving, armored vehicles will also be used in extreme environmental conditions, such as ...
