Integrated vibration reduction and isolation system for unmanned vehicles adapting to broadband

Abstract

The disclosure of the present invention relates to an integrated vibration reduction and isolation system for unmanned vehicles adapting to a wide frequency band, and relates to the technical field of mechanical engineering. The vibration reduction and isolation assembly includes: the upper connection plate is connected with the upper chassis; The disc is connected with the mechanical axle; a pair of upper ear plates are fixed parallel to the lower surface of the upper connection plate, and an air-avoiding area is formed between the pair of upper ear plates; the ends of the lower ear plates are fixed on the lower connecting plate The upper surface of the disc, and the lower ear plate is inserted into the air-avoiding area, and the lower ear plate moves vertically up and down relative to the pair of upper ear plates through the connecting piece; a coil spring. The technical solution disclosed in the present disclosure ensures the four-wheel grip while achieving the purpose of energy consumption. At the same time, in order to reduce the impact and damage of the inertia on the vehicle body, the vehicle body can roll and sway along the long axis of the vehicle body, and the vehicle body is not allowed to move forward and backward in the direction of travel. oscillation.

Description

technical field [0001] The disclosure of the present invention relates to the field, in particular to an integrated vibration reduction and isolation system for unmanned vehicles adapting to a wide frequency band. Background technique [0002] Vibration refers to all or part of an object vibrating back and forth along a straight line or a curve, with a certain time law and period. The operating environment of the unmanned vehicle in the beam yard is complex, and vibration will be generated during operations such as overcoming obstacles, which will affect the life of the equipment. The vibration reduction technology can effectively alleviate the external or internal impact of the machine tool, improve the working performance and prolong the service life of the machine tool. [0003] The requirements for vibration reduction and isolation of unmanned vehicles are relatively high. On the one hand, due to the narrow space layout of the chassis of unmanned vehicles, the conventio...

AI Technical Summary

Problems solved by technology

[0003] The requirements for vibration reduction and isolation of unmanned vehicles are relatively high. On the one hand, due to the narrow space layout of the chassis of unmanned vehicles, the conventional vibration reduction and isolation system takes up a large space and the performance configuration is relatively complicated; on the other hand, such as beam field spraying The load of the trolley is pumped in and out with the water in a large range, and the load change amplitude is large, and the inertia of the water in the vehicle is relatively large. It is difficult for the general vibration reduction and isolation system to meet the operation requirements.
