Description
技术领域technical field
本发明属于半挂车技术领域，尤其涉及一种过渡轮式防半挂车侧翻装置。The invention belongs to the technical field of semi-trailers, in particular to a transition wheel type anti-rollover device for semi-trailers.
背景技术Background technique
一般地，半挂车是车轴置于车辆重心（当车辆均匀受载时）的后面，并且装有可将水平或垂直力传递到牵引车的联结装置的挂车。半挂车主要运输体积大且不易拆分的大件货物，如挖掘机等，栅栏式半挂车则比较适合拉鲜活类的货物，如蔬菜、水果等；厢式半挂车比较适合拉散货及防湿较贵重货物。与“单体式”汽车相比，半挂车更能够提高公路运输的综合经济效益，运输效率可提高30-50%，成本降低30-40%，油耗下降20-30%。更重要的是，使用半挂车，还能对我国物流的组织形式起到一定程度的促进作用。但是，半挂车在高速时转弯很容易发生侧翻，这是一直以来半挂车的设计都无法避免的工作缺陷，严重时会造成生命危险和经济损失。Generally, a semi-trailer is a trailer whose axles are placed behind the vehicle's center of gravity (when the vehicle is evenly loaded) and equipped with hitches that transmit horizontal or vertical forces to the tractor. Semi-trailers mainly transport bulky goods that are not easy to disassemble, such as excavators, etc. Fence-type semi-trailers are more suitable for pulling fresh goods, such as vegetables, fruits, etc.; van-type semi-trailers are more suitable for pulling bulk goods and Moisture-proof more expensive goods. Compared with "single-body" cars, semi-trailers can improve the comprehensive economic benefits of road transportation, the transportation efficiency can be increased by 30-50%, the cost can be reduced by 30-40%, and the fuel consumption can be reduced by 20-30%. More importantly, the use of semi-trailers can also promote the organization of logistics in my country to a certain extent. However, the semi-trailer is prone to rollover when turning at high speed. This is an unavoidable working defect in the design of the semi-trailer, and it will cause life-threatening and economic losses in severe cases.
