Floating device of industrial vehicle

Abstract

The invention discloses a floating device of an industrial vehicle. The floating device comprises a vehicle body, driving wheels and supporting wheels, wherein the vehicle body is respectively in floating connection with the driving wheels and the supporting wheels through a first elastic device and a second elastic device. According to the floating device, the driving wheels and the supporting wheels are in floating connection with the vehicle body, so that the load capacity of the whole vehicle meets the requirement, the problem of slipping of loaded vehicles is solved, and the phenomenon of sidewise inclination during loaded steering is avoided.

Description

technical field [0001] The invention relates to the technical field of industrial vehicles, in particular to a floating device for industrial vehicles. Background technique [0002] Existing industrial vehicles, such as stackers, trucks, etc., generally include driving wheels and supporting wheels to form a traditional three-point support or five-point support. The driving wheels are used to provide power so that the entire vehicle can walk, and the supporting wheels Play the role of auxiliary support, and together with the driving wheel, the vehicle can walk smoothly. As we all know, the supporting wheel has no power, and the driving wheel and the supporting wheel are fixedly connected with the vehicle body, such as patent No. ZL200920197355.9 A kind of truck disclosed in the Chinese utility model patent, its drive wheel and universal wheel (support wheel) are all fixedly connected with the car body, people find in the process of using that the comfort of the vehicle is rel...

AI Technical Summary

Problems solved by technology

When the vehicle is empty, the elastic pre-tightening force of the elastic device cannot be adjusted too large. If it is too large, it will not achieve the effect of shock absorption. Moreover, because the elastic pre-tightening force is too large, the positive pressure of the driving wheel on the ground will be too large. The reaction force of the ground to the driving wheels will have the undesirable phenomenon of lifting the rear of the car body

However, if the elastic pre-tightening force is adjusted too small, the positive pressure of the driving wheel on the ground will be too small, and there may be a problem of heavy vehicle skidding, which will limit the load of the vehicle and cannot be made larger.
