Problems solved by technology
The huge transportation network depends on the carrying capacity of heavy-duty semi-trailers. In the future, road transportation will mainly rely on heavy-duty semi-trailers. However, the existing heavy-duty semi-trailers in my country have low technical content, and tire bursts, broken axles, etc. are prone to occur during vehicle operation. Steel plates are broken and tires are severely worn. These problems seriously affect the efficiency of road transportation and also confuse the majority of car owners.
[0003] The reason is that when driving on uneven roads, some tires will be in the air, and the suspension system of the existing heavy-duty semi-trailer cannot be solved well. At this time, the pressure on the tires on the ground exceeds the limit value and a tire burst will occur. , short springs or even broken shafts, causing serious rollover accidents in severe cases, and the losses are immeasurable

The invention relates to the field of road transportation, in particular to a semitrailer suspending device. The semitrailer suspending device comprises a front axle mechanism, a middle axle mechanism, a rear axle mechanism, lifting mechanisms, connecting rods, a first lever, a second lever and installing support seats. The left end of the front axle mechanism is hinged to the installing support seat, and the right end of the front axle mechanism is connected with the left end of the first lever through the connecting rods; the left end of the middle axle mechanism is hinged to the right end of the first lever; the left end of the rear axle mechanism is connected with the right end of the second lever through the connecting rods, and the right end of the rear axle mechanism is hinged to the corresponding installing support seat; and the lifting mechanisms are located above the front axle mechanism and the rear axle mechanism correspondingly, and the lifting mechanisms are fixedly connected with a semitrailer body and are elastically connected with the front axle mechanism and the rear axle mechanism. According to the semitrailer suspending device, one ends of the front axle mechanism, the middle axle mechanism and the rear axle mechanism are fixed and connected by adopting a hinged mode, not only is self-adaptive adjusting of the front axle mechanism, the middle axle mechanism and the rear axle mechanism according to landforms guaranteed, but also noise and abrasion of all joints are reduced.
Description
technical field [0001] The invention relates to the field of road transportation, in particular to a semi-trailer suspension device. Background technique [0002] Road transportation is one of the main modes of material transportation in my country. In order to meet the needs of material transportation, the government plans to invest 2 trillion yuan to build 52,000 kilometers of expressways. By 2030, the total mileage of expressways in my country will reach 85,000 kilometers. The huge transportation network depends on the carrying capacity of heavy-duty semi-trailers. In the future, road transportation will mainly rely on heavy-duty semi-trailers. However, the existing heavy-duty semi-trailers in my country have low technical content, and tire bursts, broken axles, etc. are prone to occur during vehicle operation. Steel plates are broken and tires are severely worn. These problems seriously affect the efficiency of road transportation and also confuse the majority of car own...
