Trailer support device with novel structures

Abstract

The invention discloses a trailer support device with novel structures, comprising a support chassis, an outer barrel, an inner barrel, a transmission mechanism and a self-suction lubricating oil cylinder, wherein the support chassis and the inner barrel are in spherical fit connection; a bearing plate is transversely pre-buried in the outer barrel and can transfer force up and down; the inner wall surface of the inner barrel adopts a differential pressure type rheological surface; the transmission mechanism adopts a lead screw and floating lead screw nuts for bearing; and the self-suction lubricating oil cylinder is arranged in the inner barrel, and the lead screw is arranged in the self-suction lubricating oil cylinder, thereby ensuring lifetime lubrication of the lead screw and the nuts. The trailer support device disclosed by the invention adopts the novel inner and outer barrel structures and the transmission mechanism, so that the material is saved, the self weight is reduced, the lifting efficiency is improved, and thus the aim of achieving greater, faster, better and more economical results is achieved.

Description

technical field [0001] The invention relates to a vehicle body support device, in particular to a support device applied to the front lower part of a trailer. Background technique [0002] The trailer supporting device is a component used when the tractor and the trailer are separated or connected, and is used to carry the mass of the front part of the trailer and keep the trailer in a horizontal state after separation. device. The trailer supporting device is divided into two groups, which are respectively installed on the left and right sides of the front bottom of the trailer to ensure the balance of the trailer. The two sets of supports can act independently, or can be linked through a connecting structure in the middle. A single support structure such as figure 1 As shown, it includes an outer cylinder 100 and an inner cylinder 200. The outer cylinder 100 is fixed on the bottom of the car body, and the crank handle 300 is connected to the transmission mechanism insid...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned present situation, the present invention provides a trailer support device with a new structure, which adopts non-metallic materials, is light in weight and has a large bearing capacity, so as to solve the current problems of heavy weight, low lifting efficiency, and low bearing safety factor.
