Steering frame of hinged frame linear electric motor

Abstract

The invention provides a steering framework of a hinged framework linear electric motor, which comprises two T-shaped frames and a horizontal frame connected with a vehicle body, wherein two T-shaped frames are mutually hinged to enable the framework to have soft connection points to be suitable for a curve with an abrupt corner so as to improve the bearing limitation of the framework on torsion force and reduce the design difficulty of the steering framework. A hanger is arranged below the horizontal frame and used for hanging a linear motor which is connected with two side beams of the framework by two transverse pulling rods. Middle parts of two side beams of the two T-shaped frames which are mutually hinged are connected with a central cross beam by rubber panel nodes. The central cross beam is connected with a traction cross beam of the upper part by longitudinal pulling rods on side parts, and central pins respectively penetrate the traction cross beam and the central cross beamto be connected into a whole structure. The traction cross beam is respectively connected with the side beams of the two T-shaped frames by an oil pressure damper, and the central cross beam is connected with the linear motor by the longitudinal traction pulling rods.

Description

technical field [0001] The invention relates to a bogie for rail vehicles, belonging to the field of mechanical manufacturing. Background technique [0002] At present, the rail vehicle bogies used in railway trains, subways and light rail transportation generally adopt rigid frame structures. Due to the influence and limitation of the wheel-rail line of the vehicle, when the wheel set travels to a curve with a sharper corner, the outer side of the rigid frame and the part close to the wheel set will bear a large torque. Moreover, when the vehicle speed is high, the connection between the frame and the primary suspension device will also be subject to a greater impact. [0003] Therefore, the above-mentioned existing rigid frame, its structure and traction force transmission mode are difficult to adapt to the use requirements of high-speed operation and complex working condition wheel-rail line to a certain extent. Correspondingly, there are high design requirements for th...

Moreover, when the vehicle speed is high, the connection between the frame and the primary suspension device will also be subject to a greater impact force

[0003] Therefore, the above-mentioned existing rigid frame, its structure and traction force transmission mode are difficult to adapt to the use requirements of high-speed operation and complex working conditions of the wheel-rail line to a certain extent.

Correspondingly, there are high design requirements for the manufacturing quality and materials of the frame, which increases the production difficulty and manufacturing cost
