Abstract

The invention discloses a crane swing suspension system, which comprises a vehicle chassis and front and rear suspensions, and is characterized in that the front suspension comprises a front suspension support fixed on the chassis, and the front suspension support It is rigidly connected with the front drive axle, and the rear suspension is hinged on the chassis through a pin shaft. The direction of the pin shaft is perpendicular to the direction of the wheel shaft. Two locking cylinders are symmetrically arranged on both sides of the pin shaft, and are installed on the rear suspension and the chassis Between the rod chamber and the rodless chamber of the locking cylinder, a control valve group controlled by an electronic control system is arranged on the connecting pipeline, and the rear suspension is rigidly connected with the rear drive axle. The crane swing suspension system of the present invention has the characteristics of being able to flexibly adapt to the load-bearing changes of the crane on different roads and industrial and mining environments, and has the characteristics of simple structure, strong bearing capacity, convenient layout, and low manufacturing cost.

Description

technical field

[0001] The invention relates to a heavy-duty vehicle, especially a suspension system of a crane. Background technique

[0002] When the crane is in a working condition such as driving with load, the axle load of the whole machine is transferred, and the single axle load can reach 80,000-90,000kg. The use of traditional leaf springs, coil springs or oil-pneumatic springs will make the components of the suspension system huge in size, high in manufacturing costs, and occupy a large space, which cannot be realized in structural design. However, if the front and rear suspensions are fully rigidly connected, it will result in:

[0003] (1) The suspension system loses the shock absorption and buffering functions, and the ride and operation comfort of the whole machine is poor;

[0004] (2) When the whole machine is driving and working on uneven roads, a single wheel will appear in the air, resulting in deterioration of wheel load distribution, damage to related c...
