Technical Field
The utility model relates to a hydraulic suspension, it is a two-wire four-axis hydraulic suspension that says so more specifically.
Background
For many years, the combined hydraulic suspension trailer (the number of the axes can be spliced) is widely applied to the transportation of large objects in the industries of electric power, chemical engineering and the like, and becomes a main tool for large road transportation. Different combinations can meet the transportation requirements of dozens of tons to thousands of tons of different goods. However, the combined hydraulic suspension trailer has high manufacturing cost and needs professional hydraulic operators when in use, so the cost for transporting goods by using the combined hydraulic suspension trailer is higher. Only when the common heavy semitrailer can not meet the transportation requirements, the combined type hydraulic suspension trailer can be used.
Compared with the combined hydraulic suspension trailer, under the condition of the same number of axes and bearing capacity, the cost and the use cost of the common heavy semitrailer with two lines, four shafts, three lines, six shafts, four lines, eight shafts and the like are much lower. However, the number of the axle lines of the common heavy semi-trailer such as two-line four-axis, three-line six-axis, four-line eight-axis and the like is fixed, so that the maximum load capacity is also fixed, and the use of the heavy semi-trailer is limited.
besides, the suspension of the existing common heavy semitrailer with the two-wire four-shaft, three-wire six-shaft, four-wire eight-shaft and the like is a rigid suspension, except that the heavy semitrailer with the two-wire four-shaft rigid suspension can ensure that each shaft can be uniformly loaded in the using process, the heavy semitrailer with the three-wire six-shaft, four-wire eight-shaft and the like rigid suspension has a very small height range of automatic adjustment of each shaft, and can generate the condition that each shaft load is seriously uneven when the heavy semitrailer runs on an uneven road section, so that some shaft loads can seriously exceed the rated load, and further serious damage is caused to a road. After the number of the axles of the heavy semi-trailer with the two-line four-axis rigid suspension is increased, the load of each axle is also seriously uneven when the heavy semi-trailer runs on an uneven road section. These all restrict the use of the common heavy semitrailer with two-line four-axis, three-line six-axis, four-line eight-axis, etc.
Therefore, it is necessary to develop a two-wire four-shaft hydraulic suspension that is as expensive as a conventional two-wire four-shaft hydraulic suspension and can maintain uniform loads on the shafts even when the hydraulic suspension is driven on uneven roads.
