The invention belongs to the technical field of rail wagons, and particularly relates to an axle box positioning device and a bogie. The axle box positioning device comprises a rotating arm and a torsion rod spring, wherein one end of the rotating arm is fixedly connected to the axle box, the other end of the rotating arm is connected with a framework through the torsion rod spring; the torsion rod spring is provided with a first end and a second end which are opposite to each other, the first end of the torsion rod spring is rotatably connected to the framework, the other end of the rotatingarm is fixedly connected with the middle of the torsion rod spring, and the second end of the torsion rod spring and the framework are oppositely and fixedly arranged. The torsion bar spring can generate large angular deformation and torque so as to enable a vehicle to have large vehicle static deflection. Meanwhile, the spring deflection difference between the empty state and the full load stateof a rail wagon is enabled to be small, and the included angle between the upper supporting surface and the lower supporting surface is small, so that the service life of the torsion rod spring is prolonged, and good practical value is achieved.
本发明属于铁路货车技术领域,尤其涉及一种轴箱定位装置以及转向架。其中的轴箱定位装置包括转臂以及扭杆弹簧,转臂的一端固定连接在所述轴箱上,所述转臂的另一端通过扭杆弹簧和构架连接,所述扭杆弹簧具有相对的第一端和第二端,所述扭杆弹簧的第一端可转动地连接在所述构架上,所述转臂的另一端和所述扭杆弹簧的中部固定连接,所述扭杆弹簧的第二端和所述构架相对固定设置。本发明可以使扭杆弹簧产生较大的角变形以及扭矩,以使车辆具有较大的车辆静挠度,同时,使铁路货车的“空车状态”和“满载状态”下的弹簧挠度差异较小,上下支撑面的夹角也较小,以增加扭杆弹簧的使用寿命,具有很好的实用价值。
