Vertical lifting hydraulic hanging mechanism

Abstract

The invention relates to a vertical lifting hydraulic hanging mechanism, comprising a hanging frame, a hydraulic cylinder, a wheel axle body, a short connecting rod, a pair of first intermediate connecting rods, a pair of second intermediate connecting rods and a pair of long connecting rods. The lengths of the first intermediate connecting rods and the second intermediate connecting rods are equal. The upper top surface of the hanging frame is connected with a lower flat surface of a vehicle, and the lower end face of the hanging frame is respectively articulated with the upper end part of the hydraulic cylinder, the upper end part of the short connecting rod and the upper end parts of the pair of long connecting rods. The lower end part of the short connecting rod is coaxially articulated with the upper end parts of the pair of first intermediate connecting rods. The lower end part of a long connecting rod, the lower end part of a first intermediate connecting rod and the upper end part of a second intermediate connecting rod are coaxially hinged. The lower end part of the other long connecting rod, the lower end part of the other first intermediate connecting rod and the upper end part of the other second intermediate connecting rod are coaxially hinged. The lower end parts of the pair of second connecting rods are coaxially articulated with the middle part of a piston rod of the hydraulic cylinder, the lower end part of the piston rod of the hydraulic cylinder is articulated with the wheel axle body, and the two ends of the wheel axle body are respectively connected with a left wheel and a right wheel. The vertical lifting hydraulic hanging mechanism has a simple structure, is easy to manufacture and is adapted to complex road surfaces, and with the adoption of thevertical lifting hydraulic hanging mechanism, tyre abrasion is reduced.

Description

technical field [0001] The invention relates to a vehicle suspension device, in particular to a hydraulic suspension mechanism for vertical lifting of a large-scale power flatbed transport vehicle, which belongs to the technical field of automobiles. Background technique [0002] The transport capacity of large-scale powered flatbed transport vehicles can reach thousands of tons or even higher, and it is widely used in shipyards, steel plants, electric power, petrochemical and other large enterprises or projects, and can also be used for the transportation of box girders. use. Due to the heavy load and many axes of this large-scale power flatbed transport vehicle, it is prone to the problem of some kind of axle overloading. After retrieval, it was found that in the Chinese patent "Hydraulic Suspension Mechanism" with the authorized announcement number CN 201419626, a hydraulic suspension mechanism is described, which consists of a balance arm, a hydraulic cylinder, and a su...

Problems solved by technology

In the suspension mechanism described in this patent, during the expansion and contraction process of the hydraulic cylinder, the movement trajectory of the wheel center is an arc, that is, the entire wheel moves up and down in an arc. This feature will increase the lateral wear between the tire and the ground, and greatly reduce the wear and tear of the tire. The service life is not conducive to saving costs for users
