The invention relates to a semi-trailer transport vehicle and a monitoring device thereof. The monitoring device comprises a rotating part which can be rotatably connected to a traction pin of a semi-trailer around a first axis; an angle sensor which comprises a sensor body and a rotating shaft part which is rotatably connected to the sensor body around a second axis, wherein one of the sensor body and the rotating shaft part is fixedly connected to the rotating part, the other one of the sensor body and the rotating shaft part is fixedly connected to the traction pin of the semi-trailer, andthe second axis is collinear with the first axis; and a connecting rod having one end fixedly connected to the rotating part, and the other end fixedly connected to a saddle of the tractor. Therefore,the rotation of the saddle of the tractor relative to the traction pin of the semi-trailer is transmitted to the angle sensor through the rotating part, namely the connecting rod is not directly connected with the angle sensor but indirectly connected with the angle sensor through the rotating part. Therefore, the impact and vibration transmitted to the angle sensor by the saddle of the tractor through the connecting rod are reduced, and the measurement precision of the angle sensor is improved.

    本发明涉及一种半挂式运输车及其监测装置。该监测装置包括:转动件,绕第一轴线可转动地连接于半挂车的牵引销;角度传感器,包括传感器本体及绕第二轴线可转动地连接于传感器本体的转轴部;传感器本体和转轴部其中一个固定连接于转动件,传感器本体和转轴部其中另一个固定连接于半挂车的牵引销,且第二轴线与第一轴线共线;及连杆,连杆的一端固定连接于转动件,另一端固定连接于牵引车的鞍座。如此,牵引车的鞍座相对半挂车的牵引销的转动通过转动件传递至角度传感器,即连杆并不与角度传感器直接连接,而是通过转动件间接连接。因此,有利于减小牵引车的鞍座通过连杆传递至角度传感器的冲击和振动,提高角度传感器的测量精度。
