Description
Technical Field
The invention relates to a hydraulic suspension, in particular to a two-wire four-shaft hydraulic suspension.
Background
For many years, the combined hydraulic suspension trailer (the axis number can be spliced) is widely applied to the transportation of large-sized objects in the industries of electric power, chemical industry and the like, and has become a main tool for the transportation of large-sized roads. Different combinations can meet the transportation needs of tens to thousands of tons of different cargoes. However, the combined hydraulic suspension trailer has high manufacturing cost, and professional hydraulic operation workers are required during use, so that the combined hydraulic suspension trailer has high cost for transporting goods. Only when the common heavy semitrailer cannot meet the transportation requirement, the combined hydraulic suspension trailer can be used.
Compared with a combined hydraulic suspension trailer, under the condition that the axial line number and the bearing capacity are the same, the manufacturing cost and the using cost of the common two-wire four-shaft, three-wire six-shaft, four-wire eight-shaft and other heavy semi-trailers are much lower. However, the axial number of the common heavy semitrailers such as two-axis, four-axis, three-axis, six-axis, four-axis and eight-axis is fixed, so that the maximum load is also fixed, and the use of the heavy semitrailer is limited.
The existing heavy semitrailers with two-wire four-shaft, three-wire six-shaft, four-wire eight-shaft and the like are rigid suspensions, and besides the heavy semitrailers with two-wire four-shaft rigid suspensions can ensure that all shafts are uniformly loaded in the use process, the heavy semitrailers with three-wire six-shaft, four-wire eight-shaft and the like are small in height range of automatic adjustment of all shafts, when the heavy semitrailers run on uneven road sections, the situation that the loads of all shafts are seriously uneven can be generated, and the axle loads can seriously exceed the rated loads of the heavy semitrailers, so that the road is seriously damaged. After the number of axes of the heavy semitrailer with the two-line four-axle rigid suspension is increased, the serious uneven load of each axle can be generated when the heavy semitrailer runs on uneven road sections. These all limit the use of common heavy semitrailers with two-wire four-axis, three-wire six-axis, four-wire eight-axis and the like.
Therefore, it is necessary to develop a two-wire four-axis hydraulic suspension which is more or less costly than a conventional two-wire four-axis hydraulic suspension and which can maintain uniform loads on each axis even when traveling on uneven roads.

in order to enable the balance beam assembly 1 to be connected with the bearing oil cylinder assembly 3 and not to raise the height of the whole vehicle, the bearing oil cylinder connecting seat 11 is of a box-shaped structure which is not sealed;
the lower end of the bearing cylinder assembly 3 is connected with the bearing cylinder connecting seat 11 through the connecting pin shaft 111, and the upper end is connected with the frame longitudinal beam 5, so that the balance beam assembly 1 and the frame longitudinal beam 5 are changed from rigid connection into hydraulic connection, namely, the hydraulic suspension with functions similar to those of a combined type hydraulic suspension trailer is changed, therefore, the multi-axis semitrailer manufactured or spliced by the invention can be like the combined type hydraulic suspension trailer, when the vehicle runs on uneven road, the bearing cylinder assembly 3 has the advantages of stretching and shortening, and the wheels of each shaft can be contacted with the ground, and because the oil paths of the bearing cylinder assemblies 3 are connected in series, the oil pressure of the bearing cylinder assemblies 3 is the same, namely, the load of the bearing cylinder assemblies 3 is the same, and the load born by each shaft in use is ensured to be uniform;
the balance beam assembly 1 can rotate around the connecting pin shaft 111, so that the front axle assembly 4 and the rear axle assembly 4 connected with the balance beam assembly 1 are balanced;
