The invention relates to a special fluid director for a semi-trailer tractor, the semi-trailer tractor and the technical field of fluid directors for vehicles, and the special fluid director comprisesa link pad, two first telescopic rods, two second telescopic rods, two third telescopic rods, two support rods and two pieces of tarpaulin. Due to the fact that the first, second and third telescopicrods are all provided with Compressible sections and stretchable sections, and the compressible sections are connected with the link pad, the first stretchable section and the second stretchable section can be magnetically attracted to the semitrailer, and the fluid director can be disengaged from the semitrailer when the semitrailer turns and can be automatically connected with the semitrailer again after the semitrailer turns. In addition, tarpaulin is arranged on the left side face and the right side face of the gap between the semitrailer and the tractor, and the tarpaulin can play a rolein guiding flow in the running process of the semitrailer tractor. Therefore, the limit steering requirement of the semitrailer tractor can be met, and the wind resistance of the front end of the semitrailer can be reduced.
本申请涉及一种半挂牵引车专用导流器及半挂牵引车,车辆用导流器技术领域,包括链接垫、两第一伸缩杆、两第二伸缩杆、两第三伸缩杆、两支撑杆和两篷布,由于第一伸缩杆、第二伸缩杆和第三伸缩杆均设为可压缩段和可拉伸段,且可压缩段均与链接垫连接,同时第一可拉伸段和第二可拉伸段均可磁吸于半挂车上,导流器在半挂牵引车转弯时可与半挂车脱开,并在半挂牵引车转弯结束后又能自动与半挂车重新接合;此外,在半挂车与牵引车之间空隙的左右两侧面均设有篷布,该篷布可在半挂牵引车行驶过程中起到导流作用。因此,本申请不仅能满足半挂牵引车极限转向的需求,还可减小半挂车前端的风阻。
