Problems solved by technology

[0004] For this kind of linear motor suspension connection structure, how to solve the problem that the fastening bolts of the rubber nodes are easy to loosen and rotate while elastically connecting has always been a relatively complicated technical issue.
[0005] When the fastening bolts are loosened or rotated, the radial shear force generated between the fastening bolts and the mounting seat due to the vertical weight of the linear motor may easily lead to the breakage of the fastening bolts, thereby affecting the suspension of the linear motor. safety and reliability

Abstract

The invention provides a device and method for suspending a linear motor of a railway vehicle. A positioning mode that fastening bolts pass through laterally positioned bolts is adopted and a double fastening means for resisting vertical loosening and lateral rotation of the fastening bolts is realized, so that the phenomenon that abnormal connection of the fastening bolts influences the reliability of mounting the linear motor can be avoided. The device comprises a support box which is arranged at an axle end part of each wheel set by a bearing and used for suspending a lateral suspension beam of the linear motor, and the end part of the lateral suspension beam is supported on the support box elastically by rubber nodes. The top of the support box is provided with a pair of convex mounting seats; a group of fastening bolts is used for vertically mounting the rubber nodes at two ends of the lateral suspension beam on the mounting seats respectively; positioning nuts are laterally inserted into the mounting seats and provided with internal threaded holes through which the fastening bolts vertically pass; and the fastening bolts are used for vertically mounting the rubber nodes on the mounting seats of the support box, thus vertically positioning the end parts of the lateral suspension beam from top to bottom.

Description

technical field [0001] The invention relates to a suspension device for a rail vehicle linear motor and a 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] In the existing technical solution, the linear motor is installed under the support box at both ends of the axle through a pair of transverse suspension beams. In order to ensure that the transverse suspension beam can perform limited axis rotation around its installation point, and to deal with the small swing of the linear motor relative to the bogie during vehicle driving, rubber nodes are usually used to elastically carry the transverse suspension beam on the support box. [0004] For this type of linear motor suspension connection structure, ...
