Abstract

The invention relates to a railway vehicle linear motor bogie and a manufacturing method thereof, wherein a split suspension structure is adopted on a framework and a linear motor and the characteristics of the traditional linear motor bogie such as space design, force distribution and the like are changed so as to further optimize the running stability of the bogie, reduce the vibration, realize the distribution balance of the framework load and linear motor load on a wheel axle, improve the stress state of a wheel set, restrain the bending deflection of the wheel set and solve the problem of large vibration of axle ends. The bogie comprises two wheel sets, a framework and a linear motor, wherein two axle box bodies which are symmetrically arranged are loaded on wheel axles of each wheel set; two support box bodies which are symmetrically arranged are installed on the wheel axles of each wheel set through a bearing; two end of a cross suspension beam are elastically arranged on the two support box bodies of each wheel set; the linear motor is connected to each cross suspension beam by utilizing a plurality of vertical suspenders; and an axle box body and a support box body are respectively arranged at two sides of each wheel set on a same wheel axle.

Description

technical field [0001] The invention relates to a linear motor radial bogie for rail vehicles and a manufacturing method thereof, belonging to the field of mechanical manufacturing. Background technique [0002] With the rapid increase of the speed of domestic trunk railways and the rapid development of urban rail transit, linear motor radial bogies are gradually gaining overall technological Leading edge and market recognition. [0003] For example, the Chinese patent application for the following content is disclosed, the application number is 200610171237.1, and the name is a track bogie with a linear induction motor. In the left and right axle boxes: a bogie frame, which is supported on the axle box by the first suspension device and is provided with a second suspension device for supporting the car body; one or two transverse members, which are respectively connected by left and right elastic Mounting means mounted on one of the pair of left and right axle boxes, said...
