The invention discloses an angle measuring device and a semi-trailer transport vehicle. The angle measuring device is arranged on the semi-trailer transport vehicle. The semi-trailer type transport vehicle comprises a tractor and a semi-trailer, and the semi-trailer is rotationally connected with the tractor through a traction pin. The traction pin and the semitrailer are static relatively, and the traction pin and the tractor rotate relatively. The angle measuring device comprises a guide wheel and an angle sensor, the guide wheel is arranged on the tractor, the outer wall of the guide wheel is in contact with the outer wall of the traction pin, and the traction pin drives the guide wheel to rotate under the condition that the semi-trailer transport vehicle turns. The angle sensor is used for detecting the rotation angle of the guide wheel so as to obtain the rotation angle of the traction pin and further obtain the relative angle of the semitrailer and the tractor. The angle measuring device is high in measuring accuracy, and meanwhile, the influence on the strength of the traction pin is reduced, so that the safety of the semi-trailer transport vehicle is improved.
本申请公开了一种角度测量装置和半挂式运输车。上述角度测量装置设置于半挂式运输车。该半挂式运输车包括牵引车和半挂车,半挂车通过牵引销与牵引车转动连接。牵引销与半挂车相对静止,牵引销与牵引车相对转动。上述角度测量装置包括导轮和角度传感器,其中,导轮设置于牵引车,导轮的外壁与牵引销的外壁接触,在半挂式运输车转弯的情况下,牵引销驱动导轮转动。角度传感器用于检测导轮的转动角度,从而得出牵引销的转动角度,进而得出半挂车与牵引车的相对角度。上述角度测量装置测量准确度高,同时还减小了对牵引销的强度的影响,从而提高了半挂式运输车的安全性。
