Bearing and damping device for crawler-type locomotive platform

Abstract

The invention relates to a bearing and damping device for a crawler-type mobile platform, which is a mechanical type suspension system which is suitable for a small and medium size crawler-type locomotive platform and has the advantages of strong bearing capacity, good damping effect and high cost performance. The bearing and damping device comprises four X swing arm components, a V swing arm component, springs and other parts. A bearing function of the bearing and damping device is realized through spring systems arranged on the X swing arms and the V swing arm, the elastic force of the springs horizontally placed on the swing arms is amplified in multiples through a force boosting lever principle so as to improve the main body bearing capacity and the part damping capacity; multiple damping can be realized through the deformation of the springs and the swinging of the X swing arms and the V swing arm; small-amplitude high-frequency turbulence vibration in the vertical direction is converted to the horizontal direction by utilizing the X swing arms and absorbed by the horizontally and oppositely arranged springs; large-amplitude low-frequency vibration is buffered and absorbed by utilizing the structural characteristic of the V swing arm, so that a quite obvious damping effect is applied on the platform; and mechanical limit is taken into account in the part design, so that the stability and the reliability of the bearing and damping device can be guaranteed.

Description

technical field [0001] The invention relates to a load-bearing and shock-absorbing device suitable for various light-duty crawler-type mobile platforms, especially small and medium-sized crawler-type mobile robots. The load-bearing and shock-absorbing performance of the crawler-type motorized platform and the stability and reliability of the movement. Background technique [0002] The suspension of the crawler mobile platform is very important. It connects the body and the track to ensure that the platform can run smoothly and reliably on uneven roads at a certain speed. Suspensions can generally be divided into three types: rigid suspensions, semi-rigid suspensions and elastic suspensions. Although the first two types of suspensions are simple in structure and low in cost, the impact of the ground is directly or slightly attenuated and transmitted to the body, and the shock absorption effect is poor. A platform that does not require high stability; while the elastic suspe...
